A processing system may have a plurality of nodes that may be linked together within a network. The processing system can be a control system wherein some nodes may include software and/or hardware that may be configured to operate various systems in one or more facilities (i.e., enclosures). Facilities can include at least one building or any portion(s) of the building. The operating systems to be controlled can include smart windows (e.g., having insulated glass units such as electrochromic devices), building management systems, environmental sensors, and/or actuators (e.g., HVAC systems). When deploying processing hardware (e.g., and software) system including multiple processing nodes in order to create and maintain an on-premises, hierarchical controller network; it is at times commissioned by labor intensive and lengthy assignment of the nodes (e.g., control nodes among many control and functional elements) that is entirely, or at least partially, manual. When new nodes are added to a preformed system, these newly added nodes typically also require manual, or at least partially manual, assignment to the system; oftentimes including reprogramming the existing system to accommodate the new node(s). Such manual installation methodology can result in substantial costs and/or can be prone to human error. The human errors can lead to detrimental malfunction of such a complex system and/or compromise of data security.
Various aspects disclosed herein alleviate as least part of the shortcomings related to commissioning multiple processing nodes in an on-premises network.
In an aspect, software setup and installation (i.e., commissioning) of the nodes can occur automatically, e.g., by pre-installing a self-orchestrating control scheme in each of the nodes (e.g., processors). The cost, labor, maintenance, and/or support associated with deployment of a processing system can be reduced while avoiding many potential sources of human error. A self-orchestrating system can provide increased robustness by avoiding a single point of failure (e.g., due to a malfunction of a single node).
In another aspect, a method for deployment of at least one work order, the method comprises: (a) activating a plurality of nodes as observer agents, which plurality of nodes forms a cluster; (b) using an observer agent of the observer agents to broadcast a query to the cluster and wait for a response, which query inquires whether any of the plurality of nodes is assigned a role of a Master Node; (c) if the observer agent does not receive a positive response to the query, assigning (i) the role of the Master Node to the observer agent and (ii) a role of a Worker Node to any node of the plurality of nodes different from the Master Node to form at least one Worker Node; and (d) using the Master Node to (I) retrieve at least one work order and (II) orchestrate the at least one work order among any of the at least one Worker Node.
In some embodiments, the deployment of at least one work order is deployment of at least one work order in a local network of a facility (e.g., the first network implemented in the facility upon its construction, and/or a network disposed at least in part in an external envelope of the facility). In some embodiments, the plurality of nodes is disposed in a facility and is operatively couped to the local network of the facility. In some embodiments, the Master Node deploys the at least one work order to the at least one Worker Node. In some embodiments, the at least one Worker Node is communicatively coupled to at least one device disposed in the facility (e.g., in an enclosure of the facility). In some embodiments, the at least one device is included in a device ensemble comprising sensors or a sensor and an emitter. In some embodiments, the network is configured to transmit communication and power on one cable (e.g., a coaxial cable). In some embodiments, the communication comprises cellular communication conforming to at least a third generation (3G), fourth generation (4G), or fifth generation (5G) cellular communication protocol. In some embodiments, the communication comprises media or control communication. In some embodiments, the network is operatively coupled to a control system configured to control an environment, or a messaging system (e.g., an alarm system, a safety system, a health system, an entertainment system, or an educational system) of the facility. In some embodiments, the at least one work orders include one or more commands for operating the device.

In some embodiments, a building management system (BMS) is a computer-based control system installed in a building that monitors and otherwise controls (e.g., regulates, manipulates, restricts, directs, monitors, adjusts, modulates, varies, alters, restrains, checks, guides, and/or manages) the building. For example, the BMS may control the mechanical and/or electrical equipment such as ventilation, lighting, power systems, elevators, fire systems, and/or security systems. Controllers (e.g., nodes and/or processors), e.g., as described herein, may be suited for integration with a BMS. A BMS may consist of hardware, including interconnections by communication channels to one or more computers (e.g., and associated software) for maintaining one or more conditions in the building. The one or more conditions in the building may be according to preference(s) set by a user (e.g., an occupant and/or a building manager). For example, a BMS may be implemented using a local area network, such as Ethernet. The software can be based on, e.g., internet protocols and/or open standards. One example is software from Tridium, Inc. (of Richmond, Va.). One communication protocol that can be used with a BMS is BACnet (building automation and control networks). A node can be any addressable circuitry. For example, a node can be a circuitry that has an Internet Protocol (IP) address.
In some embodiments, a BMS may be implemented in a building, e.g., a multi-story building. The BMS may function (also) to control one or more characteristics of an environment in the building. The one or more characteristics may comprise: temperature, carbon dioxide levels, gas flow, and/or humidity in a building. There may be many mechanical devices that are controlled by a BMS such as heaters, air conditioners, blowers, and/or vents. To control the building environment, a BMS may turn on and off these various devices under defined conditions. A core function of a BMS may be to maintain a comfortable environment for occupants of the environment, e.g., while minimizing heating and cooling costs/demand. A BMS can be used to control the various systems. A BMS may be used to optimize the synergy between various systems. For example, the BMS may be used to conserve energy and lower building operation costs. The multi-story building may have at least 2, 8, 10, 25, 50, 80, 100, 120, 140, or 160 floors that are controlled by the control system. The number of controlled by the control system may be any number between the aforementioned numbers (e.g., from 2 to 50, from 25 to 100, or from 80 to 160). The floor may be of an area of at least about 150 m2, 250 m2, 500 m2, 1000 m2, 1500 m2, or 2000 square meters (m2). The floor may have an area between any of the aforementioned floor area values (e.g., from about 150 m2to about 2000 m2, from about 150 m2to about 500 m2, from about 250 m2 to about 1000 m2, or from about 1000 m2 to about 2000 m2).
In some embodiments, a window controller can be integrated with a BMS. For example, the window controller can be configured to control one or more tintable windows (e.g., electrochromic windows). In one embodiment, the one or more electrochromic windows include at least one all solid state and inorganic electrochromic device, but may include more than one electrochromic device, e.g. where each lite or pane of an IGU is tintable. In one embodiment, the one or more electrochromic windows include only all solid state and inorganic electrochromic devices. In one embodiment, the electrochromic windows are multistate electrochromic windows. Examples of tintable windows can be found in, in U.S. patent application Ser. No. 12/851,514, filed on Aug. 5, 2010, and titled “Multipane Electrochromic Windows,” which is incorporated herein by reference in its entirety.
In some embodiments, a local controller is communicatively coupled to at least one device. A local controller can be disposed in a separate location from the device (e.g., electrochromic window, a sensor, or an emitter) that it controls or be integrated into that device. For simplicity, in the example shown in
In some embodiments, a BMS includes a multipurpose controller, e.g., as described herein. By incorporating feedback (e.g., of the controller), a BMS can provide, for example, enhanced: 1) environmental control, 2) energy savings, 3) security, 4) flexibility in control options, 5) improved reliability and usable life of other systems (e.g., due to decreased reliance thereon and/or reduced maintenance thereof), 6) information availability and/or diagnostics, 7) higher productivity from personnel in the building (e.g., staff), and various combinations thereof. These enhancements may derive automatically controlling any of the devices. In some embodiments, a BMS may not be present. In some embodiments, a BMS may be present and may not communicate with a master network controller. In some embodiments, a BMS may communicate with a portion of the levels in the hierarchy of controllers. For example, the BMS may communicate (e.g., at a high level) with a master network controller. In some embodiments, a BMS may not communicate with a portion of the levels in the hierarchy of controllers of the control system. For example, the BMS may not communicate with the local controller and/or intermediate controller. In certain embodiments, maintenance on the BMS would not interrupt control of the devices communicatively coupled to the control system.
In some embodiments, a processing system may maintain a hierarchical control structure. The processing system (e.g., programmable processor-based networks and/or controller networks) may coordinate operation of electronic components (e.g., electronic devices and/or systems) installed at an enclosure. The enclosure may be a facility of an entity/enterprise such as a building. However, the physical processing devices or units (e.g., nodes) materializing these hierarchical roles may have a layout or interconnection that varies from (e.g., may not reflect) the layers shown. The nodes can be adapted to operate in a labile fashion. The labile fashion may enable the nodes to emulate changeable hierarchical control structures.
In some embodiments, the processing nodes are organized into a hierarchical structure. Although the processing system may implement the hierarchical control scheme, the structure of individual processors and/or nodes and their interconnections giving rise to the hierarchical scheme, may be organized in a manner that does not have to physically conform to such a hierarchy (and which may change dynamically during operation). A hierarchical control scheme can have levels and/or organization of functions. For example, a hierarchy can comprise two, three, four, or five levels.
In some embodiments, the control system has a hierarchal structure. A hierarchical structure (control scheme and/or hardware organization) may be useful for larger systems wherein (I) higher-level node(s) perform higher level functions (e.g., computations, command generation, data collection, data distribution, data communication, and/or data authentication) and (II) lower-level nodes perform lower-level functions (e.g., direct control of operational devices such as IGU, by using sensor measurements and/or Al). The functions of the lower level nodes may be performed according to programming and/or in response to commands via higher level and/or user input. Higher level input may refer to input from higher level in the hierarchy of controllers. Some examples of hierarchical systems include (a) a smart building (e.g., with interacting systems), (b) insulated glass units or IGUs (including electrochromic devices), (c) a BMS, (d) a network of sensors, (e) a collection of control devices (e.g., HVAC components), (f) data centers (either local or distributed), (g) server farms, (h) data storage facilities, (i) data security services, (j) cellular service provider facilities such as a cellular base station (e.g., for handset tracking and call provisioning). The smart building can be a facility. The facility may comprise a room, a building, several buildings, or a collection of portions from one or more buildings.
In some embodiments, deployment of the hierarchy of controllers in the facility may be elaborate. The control systems may provide advantages in scaling and reliability of installations. Some known hierarchical systems have required extensive manual layout, selection, and/or configuration of nodes, e.g., according to the intended construction and/or capabilities of the individual installations. As the number of nodes and/or functionalities increase, the set-up and modification to a network can become increasingly complex and labor intensive. Such manual installation methodology can result in substantial costs and/or can be prone to human error. The human errors can lead to (e.g., detrimental) malfunction of such a complex system and/or compromise of data security.
In some embodiments, a processing system has a hierarchical structure including a master controller at a highest level, floor controllers (e.g., that may comprise network controllers) at an intermediate level, and local controllers (e.g., window controllers) at a lowest level.
In some embodiments, the sensor(s) are operatively (e.g., communicatively) coupled to at least one controller and/or processor. Sensor readings may be obtained by one or more processors and/or controllers. A controller may comprise a processing unit (e.g., CPU or GPU). A controller may receive an input (e.g., from at least one sensor). The controller may comprise circuitry, electrical wiring, optical wiring, socket, and/or outlet. A controller may deliver an output. A controller may comprise multiple (e.g., sub-) controllers. The controller may be a part of a control system. A control system may comprise a master controller, a floor (e.g., comprising network controller) controller, or a local controller. The local controller may be a window controller (e.g., controlling an optically switchable window), enclosure controller, or component controller. For example, a controller may be a part of a hierarchal control system (e.g., comprising a main controller that directs one or more controllers, e.g., floor controllers, local controllers (e.g., window controllers), enclosure controllers, and/or component controllers). A physical location of the controller type in the hierarchal control system may be changing. For example: (I) at a first time: a first processor may assume a role of a main controller, a second processor may assume a role of a floor controller, and a third processor may assume the role of a local controller; (II) at a second time: the second processor may assume a role of a main controller, the first processor may assume a role of a floor controller, and the third processor may remain with the role of a local controller; and (III) at a third time: the third processor may assume a role of a main controller, the second processor may assume a role of a floor controller, and the first processor may assume the role of a local controller. A controller may control one or more devices (e.g., be directly coupled to the devices). Direct coupling between a first controller and a first device may refer to an absence of any other (second) controller or (second) device between the first controller and the first device. The coupling may facilitate direct communication. The coupling may be wireless and/or wired. A controller may be disposed proximal to the one or more devices it is controlling. For example, a controller may control an optically switchable device (e.g., IGU), an antenna, a sensor, and/or an output device (e.g., a light source, sounds source, smell source, gas source, HVAC outlet, or heater). The output device may be referred to herein as an “emitter.”
In one embodiment, a floor controller directs at least one local controller. A floor controller may direct one or more window controllers, one or more enclosure controllers, one or more component controllers, or any combination thereof. The floor controller may comprise a network controller. The floor (e.g., comprising network) controller may control a plurality of local (e.g., comprising window) controllers. A plurality of local controllers may be disposed in a portion of a facility (e.g., in a portion of a building). The portion of the facility may be a floor of a facility. For example, a floor controller may be assigned to a floor. In some embodiments, a floor may comprise a plurality of floor controllers, e.g., depending on the floor size and/or the number of local controllers coupled to the floor controller. For example, a floor controller may be assigned to a portion of a floor. There may be one or more floor controllers in a floor of a facility (e.g., depending on the floor size and/or number of devices in the floor that are coupled to the control system). For example, a floor controller may be assigned to a portion of the local controllers disposed in the facility. For example, a floor controller may be assigned to a portion of the floors of a facility. A master controller may be coupled to one or more floor controllers. The floor controller may be disposed in the facility. The master controller may be disposed in the facility, or external to the facility. The master controller may be disposed in the cloud. A controller may be a part of, or be operatively coupled to, a building management system.
In some embodiments, a plurality of devices may be operatively (e.g., communicatively) coupled to the control system. The plurality of devices may be disposed in a facility (e.g., including a building and/or room). The control system may comprise the hierarchy of controllers. The devices may comprise an emitter, a sensor, or a window (e.g., IGU). The device may be any device as disclosed herein. At least two of the plurality of devices may be of the same type. For example, two or more IGUs may be coupled to the control system. At least two of the plurality of devices may be of different types. For example, a sensor and an emitter may be coupled to the control system. At times the plurality of devices may comprise at least 20, 50, 100, 500, 1000, 2500, 5000, 7500, 10000, 50000, 100000, or 500000 devices. The plurality of devices may be of any number between the aforementioned numbers (e.g., from 20 devices to 500000 devices, from 20 devices to 50 devices, from 50 devices to 500 devices, from 500 devices to 2500 devices, from 1000 devices to 5000 devices, from 5000 devices to 10000 devices, from 10000 devices to 100000 devices, or from 100000 devices to 500000 devices). For example, the number of windows in a floor may be at least 5, 10, 15, 20, 25, 30, 40, or 50. The number of windows in a floor can be any number between the aforementioned numbers (e.g., from 5 to 50, from 5 to 25, or from 25 to 50). At times the devices may be in a multi-story building. At least a portion of the floors of the multi-story building may have devices controlled by the control system (e.g., at least a portion of the floors of the multi-story building may be controlled by the control system). For example, the multi-story building may have at least 2, 8, 10, 25, 50, 80, 100, 120, 140, or 160 floors that are controlled by the control system. The number of floors (e.g., devices therein) controlled by the control system may be any number between the aforementioned numbers (e.g., from 2 to 50, from 25 to 100, or from 80 to 160). The floor may be of an area of at least about 150 m2, 250 m2, 500 m2, 1000 m2, 1500 m2, or 2000 square meters (m2). The floor may have an area between any of the aforementioned floor area values (e.g., from about 150 m2to about 2000 m2, from about 150 m2to about 500 m2, from about 250 m2 to about 1000 m2, or from about 1000 m2 to about 2000 m2). The facility may comprise a commercial or a residential building. The residential facility may comprise a multi or a single family building. The one or more devices may comprise a sensor. The sensor may be configured (e.g., designed) to measure one or more environmental characteristics, for example, temperature, humidity, ambient noise, carbon dioxide, VOC, particulate matter, oxygen, and/or any other aspects of an environment (e.g., atmosphere thereof). The control system may be configured to control at least one environmental characteristic of the facility (including an enclosure of the facility) The at least one environmental characteristic may comprise temperature, humidity, fine spray (e.g., aerosol), sound, electromagnetic waves (e.g., light glare, and/or color), gas makeup, gas concentration, gas speed, vibration, volatile compounds (VOCs), debris (e.g., dust), or biological matter (e.g., gas borne bacteria and/or virus). The gas(es) may comprise oxygen, nitrogen, carbon dioxide, carbon monoxide, hydrogen sulfide, Nitric oxide (NO) and nitrogen dioxide (NO2), inert gas, Nobel gas (e.g., radon), chlorophore, ozone, formaldehyde, methane, or ethane. For example, the control system may control temperature, carbon dioxide levels, and/or humidity in an enclosure. The control system may utilize a building management system (BMS), e.g., for the environmental control. The one or more devices may comprise a sounds system, lighting, ventilation system, heating system, cooling system, heating ventilation and air conditioning system (HVAC), control entry system (e.g., electrical doors), windows (e.g., tintable windows such as electrochromic windows), dispensers, third party service devices (e.g., vending machine), machinery (e.g., factory machinery such as heavy machinery), media display (e.g., digital data screen such as television screens), communication hubs, antenna, air circulation system air sanitation systems, other sanitation systems, safety (e.g., alarm) systems, messaging systems, servers (e.g., data servers), sensing system, emission systems (e.g., light, gas, and/or volatile compounds such as smell conditioners), or any combination thereof. The dispensers may dispense liquid, foam, gel, or gas. The dispensers may dispense one or more products (e.g., syringe, medication, goggle, and/or mask). The dispensers may dispense safety, health, and/or identification products (e.g., ID cards). The dispensers may be dispense entertainment, and/or manufacturing related products (e.g., nuts, bolts, screws, or screw drivers). The dispensers may dispense work tools. The control may rely on sensor data (e.g., using feedback and/or closed loop control schemes).
In some embodiments, the control system includes at least one controller. The controller may monitor and/or direct (e.g., physical) alteration of the operating conditions of the apparatuses, software, and/or methods described herein. Control may comprise regulate, manipulate, restrict, direct, monitor, adjust, modulate, vary, alter, restrain, check, guide, or manage. Controlled (e.g., by a controller) may include attenuated, modulated, varied, managed, curbed, disciplined, regulated, restrained, supervised, manipulated, and/or guided. The control may comprise controlling a control variable (e.g. temperature, power, voltage, and/or profile). The control can comprise real time or off-line control. A calculation utilized by the controller can be done in real time, and/or off-line. The controller may be a manual or a non-manual controller. The controller may be an automatic controller. The controller may operate upon request. The controller may be a programmable controller. The controller may be programed. The controller may comprise a processing unit (e.g., CPU or GPU). The controller may receive an input (e.g., from at least one sensor). The controller may deliver an output. The controller may comprise multiple (e.g., sub-) controllers. The controller may be a part of a control system. The control system may comprise a master controller, floor controller, local controller (e.g., enclosure controller, or window controller). The controller may receive one or more inputs. The controller may generate one or more outputs. The controller may be a single input single output controller (SISO) or a multiple input multiple output controller (MIMO). The controller may interpret the input signal received.

The controller may comprise a user interface. The user interface may comprise (or operatively coupled to) a keyboard, keypad, mouse, touch screen, microphone, speech recognition package, camera, imaging system, or any combination thereof. The outputs may include a display (e.g., screen), speaker, or printer.
In some embodiments, a floor controller (e.g., a network controller) comprises circuitry. Examples of controllers (e.g., and circuitry thereof) are described in U.S. Pat. No. 10,495,939, issued Dec. 3, 2019, titled “CONTROLLERS FOR OPTICALLY-SWITCHABLE DEVICES,” which is incorporated herein by reference in its entirety. In some embodiments, a floor controller can take over some of the functions, processes and/or operations of a master controller. The floor controller can include additional functionalities and/or capabilities not described with reference to the master controller.
In some embodiments, a higher hierarchy controller (HHC) includes one or more modules (e.g., functionalities). For example, the HCC can have one or more modules including protocol conversion module, a data logger, an analytics module, a database manager, a tint determination module, a power management module, and/or a commissioning module. The HCC can include a downstream network interface links, e.g., that link the HHC to one or more lower hierarchy controllers (e.g., local controllers or intermediate controllers of lower hierarchy than the HHC). The HHC can be connected by an upstream network interface to a master controller or any intermediate controller that is in a higher hierarchy than the HHC. The HCC can comprise or be communicatively coupled to a database.
In some embodiments, a plurality of nodes of a processing system may be provided throughout a facility.
In some embodiments, a plurality of installed nodes is commissioned using an automatically performed process (e.g.., autonomously). The nodes can be interconnected as a cluster to form a processing system according to a desired hierarchical scheme and functionality. The nodes may have (e.g., substantially) identical hardware and/or software capabilities, e.g., so that the physical placement and/or interconnection of the nodes into the cluster can be conducted with minimal (e.g., without) manual selection, configuration, and/or assignment requiring foreknowledge of the intended configuration of the processing system. The physical location of any of the nodes may not be important. The self-orchestrating nodes may be communicatively coupled to a local communication link.
In some embodiments, at least one master (e.g., supervisor) node is assigned in a cluster, and at least one slave (e.g., subordinate) node is assigned in a cluster, which slave node may be controlled by the master node. For example, the master can direct one or more requests to the slave node. Assigning the master node may be according to a scheduling and/or organizational scheme (e.g., algorithm). The scheduling scheme may comprise a voting based scheme, circular order (e.g., cyclic executive scheme), randomly, first in—first out (abbreviated herein as “FIFO”), or based on distance from a (e.g., predetermined) anchor. According to the circular order assignment of node may be done in a predetermined order (e.g., circular order) without priority. According to the FIFO scheme (e.g., first come—first served), the first reporting node (e.g., “head” of the queue of node) may be assigned as a master first. According to the circular order scheme (a.k.a., round robin), assignment of node may be done in a predetermined order (e.g., circular order) without priority. The order may be predetermined based on money or more criteria comprising complexity of the cluster (e.g., as disclosed herein), structural aspects(s) of at least a portion of the facility, or functional aspects of at least a portion of the facility. In the random scheme, the master is randomly assigned among nodes in a system. The anchor may be determined based at least in part on a position of a certain client (e.g., device) density of devices in at least a portion of the facility (e.g., enclosure(s) in which the cluster is deployed), structural facility aspect, functional facility aspect, any special point of interest, network related positions (e.g., communication gate to the cloud and/or to the main controller). The anchor may relate to the physical density of at least a portion of the nodes in the facility.
In some embodiments, each node implements an Observer Agent. In some embodiments, the Observer Agents mutually scan for the availability of hosts (e.g., other nodes, including their processing hardware and/or software). The mutual scan can be during initialization (e.g., boot-up) of a processing system and/or at various times during operation. Observer Agents may interact to cooperatively define roles for the discovered hosts. The roles to be assigned can include a Master (i.e., Supervisor) role and a Worker (i.e., Slave) role. In some embodiments, a node assigned to be a Master node may retrieve a service deployment document (e.g., from a Cloud and/or from a node of a higher hierarchy level). The node may (e.g., subsequently) coordinate provisioning of the linked nodes, e.g., as instructed (e.g., defined) in the service deployment document. Provisioning of the linked nodes may be by downloading and installing configuration data and/or software applications. A Master node may take requests from a user and/or from other processing elements, to deploy a work order to a Worker node (e.g., a request to execute a command or to retrieve data). The master node may monitor completion of work orders. A Master node may manage (e.g., distribute) the processing load associated with work orders. In some embodiments, a Worker node controls performance of work tasks of a controlled operating system (e.g., that controls an IGU, HVAC system, or sensor), in response to commands received from a Master node. The commands may be generated in response to predetermined conditions (e.g., by a Master node) or in response to input from a human user. A Worker node may govern intelligent service(s), storage, and/or device configuration. The intelligent service may comprise artificial intelligence (abbreviated herein as “AI”).
In some embodiments, a processing system (also referred herein as a “cluster”) comprises a plurality of nodes. A node can represent any of the controllers in a processing system (e.g., any controller as shown in
In some embodiments, the orchestrator in any particular node is configured for operating according to a Master role or a Worker (e.g., subordinate) role. In one example, the orchestrators in the plurality of nodes can form a clustered environment that manages containerized applications. The containerized applications can perform various functions such as deployment, scaling, configuration, versioning, and/or rolling updates. In an orchestrator environment (e.g., Kubernetes), a master node may control (e.g., direct and/or monitor) the cluster. The control may include scheduling work, reconfiguring worker nodes, and/or responding to predetermined events. In some embodiments, a Kubernetes master node server to (i) declare application states and/or (ii) maintain a manifest file to validate and/or deploy work orders. The server may include an Application Programming Interface (abbreviated herein as “API”). The server may comprise a web-based server and/or at least one stationary server (e.g., a local server). The stationary server may be in the facility. The stationary server may be in a location other than the facility. The server may comprise one or more publicly exposed endpoints (e.g., to a defined request—response message system). A scheduler (as part of the master node) can track resource utilization, e.g., so that workloads can be balanced. A cluster store (as part of the master node) can replicate orchestration data used across the cluster, e.g., for coordination and/or state management. In some embodiments (such as Kubernetes), a master controller (as part of the master node) fulfills a requested state of the cluster by (i) monitoring the server and/or (ii) adjusting the cluster toward the desired state.
In some embodiments, a processing unit is included in at least one (e.g., in each) node. The processing unit may be configured to have sufficient computational power for embodying an observer agent and an orchestrator. For example, a node can be a local controller (e.g., a window controller) that, in addition to being provisioned with an observer agent and an orchestrator, is configured to control at least one insulated glass unit (“IGU”). The node can be assigned to have a role of a Master Node or a Worker node. The node can receive and execute downloadable apps for one or more functions and/or services, such as machine learning apps, message brokers, and/or weather prediction. In some embodiments, a local controller (e.g., processing unit) can comprise a window controller, e.g., as disclosed in U.S. Pat. No. 10,533,892, issued Jan. 14, 2020, entitled “MULTI-SENSOR DEVICE AND SYSTEM WITH A LIGHT DIFFUSING ELEMENT AROUND A PERIPHERY OF A RING OF PHOTOSENSORS AND AN INFRARED SENSOR,” that is incorporated herein by reference in its entirety.
In some embodiments, a window controller is generally operable and/or adapted to drive optical state transitions in, or to maintain the optical states of, one or more coupled optically-switchable devices (e.g., electrochromic devices (ECDs)). In some implementations, a processing unit can be implemented with any suitable logic device. The logic device may comprise a processor. The logic device may be configured to perform any of the functions and/or processes described herein. In some implementations, the processing unit comprises a microcontroller (also referred to as a “microcontroller unit” (abbreviated herein as “MCU”)). The processing unit can comprise a microcontroller designed for embedded application(s). For example, the processing unit may include a processor core (for example, a 200 MHz processor core) and a program memory (for example, a 2018 KB or other suitable non-volatile memory), a random-access memory (RAM) (for example, a 512 KB or other suitable RAM), and one or more input-output (abbreviated herein as “I/O”) interfaces. The program memory can include, for example, code executable by the processor core to implement the functions, operations or processes of the processing unit.
In some embodiments, a plurality (e.g., all) of the nodes are communicatively coupled. The physical locations of the nodes can be immaterial. In some embodiments, one or more (e.g., all) self-orchestrating nodes are connected via a local link. In some embodiments, one or more (e.g., all) of the nodes can be located at a single facility (e.g., site), or at a single enclosure. The facility and/or enclosure may be accessible via a cloud, and/or remotely. A node may comprise a controller, an actuator, a BMS system (e.g., HVAC system) or be communicatively coupled thereto.
In some embodiments, the plurality of nodes forming a cluster are securely connected (e.g., via a firewall). The cluster may be for a processing system. The secure connection may be communicatively coupled the plurality of nodes to one or more remote resources, e.g., for configuring and/or managing the processing system and the services it performs. For example, the processing system may include an edge service that authenticates the communication to the remote resource(s). The remote resource(s) may include cloud-based remote resource(s). The remote resource(s) may include stationary remote resource(s). the stationary remote resource(s) may be disposed outside of the facility (e.g., in a location different from that of the facility). The edge service can retrieve from a remote location data and/or commands allowing a third party (e.g., a service provider) to define performance parameter(s) and/or configuration(s) for the processing system. The third party may be a central entity. On-site (e.g., manual) configuration and/or customization of the nodes may become unnecessary. In some embodiments, the remote resource(s) include authentication engine(s), service document store(s), container registry(s), and global orchestrator(s) (e.g., a hub for a service provider). The service document store may be a repository for a service deployment document that defines configuration data for the processing system for a particular enclosure (e.g., for a controller network in a particular building). Examples of configuration data include node layout, cardinality, node capabilities (e.g., sensors, actuators, and/or emitters), and/or target application(s). The container registry may store one or more software entities (known as containers) that are used in orchestrating operation of master and worker nodes. The global orchestrator may be responsible for populating the service document store, the container registry, and/or the authentication engine. Population may include customized data, e.g., data corresponding to one or more processing systems such as those of the third party (e.g., one or more customers of the service provider).
In some embodiments, a customer site is provided with an on-premises cluster having a plurality of nodes (e.g., see
In the example shown in
In some embodiments, a pre-existing cluster may require alteration. As part of the cluster alteration, a fifth phase of operation may be executed. The fifth phase may include using the retrieved service deployment document(s) to commission (e.g., configure and/or re-deploy) one or more of the nodes in the cluster. The cluster alteration may include (i) reconfiguration of one or more of the cluster nodes and/or introduction of one or more new nodes to the cluster. For example, the fifth phase may include reassigning master and worker roles among nodes of the cluster. The reassignment may include a symmetric exchange of roles such that an old worker becomes a new master, and an old master becomes a new worker. The reassignment may include an asymmetric exchange of roles such that an old worker becomes a new master, and an old master is eliminated (e.g., due to malfunction or utilization as a node in another cluster). The cluster alteration can include introducing a new node (e.g., a new master node or a new worker node) to the cluster. The introduction of the new node may be due to malfunction (e.g., failure) of an old node. The introduction of the new node may be with the purpose of increasing a total number of nodes. Increasing the total number of nodes may couple to increasing the number of clients that the nodes serve. The clients may comprise an IGU, a sensor, an emitter, or an antenna. In a sixth phase of operation in some embodiments, the master node retrieves predetermined container(s) from a container registry, e.g., in the cloud. The containers may comprise respective dockers. The containers may be pre-configured to perform respective application functions. Pre-configuring of containers and/or service deployment documents may be controlled by a global orchestrator. In some embodiments, after the master node rolls-out the containers and service deployment document, the processing system has been commissioned and begins to perform the intended functions. In some embodiments, one or more nodes can leave the cluster and/or one or more new nodes can join the cluster. The observer agent(s) and orchestrator(s) (i) may continue to monitor for any changes, (ii) may generate new role assignment(s) and/or (iii) may configure (or reconfigure) node(s) on an ongoing basis. In some embodiments, a seventh phase of operation includes separate commissioning at other customer sites.
In some embodiments, the first phase of operation is triggered when a plurality of nodes has been installed in an enclosure, connected together by a local network link, and powered on. A system boot-up process may be automatically launched in each node, e.g., when a respective observer agent in each node executes a method leading to all the nodes joining the cluster. The joining process may include assigning master and worker roles to the joined nodes. In some embodiments, one or more nodes are first established as having the master role. Once at least one master node is established, the hierarchy of the cluster can be initialized. Subsequently, other nodes may be permitted to join the cluster (e.g., in a worker role), e.g., by submitting a join request to the master node.
In some embodiments, enhanced coordination between nodes is provided, e.g., by making one or more additional assignments of the master role. These embodiments may comprise large clusters with nodes that are communicatively coupled (e.g., connected together by corresponding network links). The clusters may comprise at least 2, 3, 5, 10, 50 or 100 nodes. The clusters may comprise any number of nodes between the aforementioned nodes in a cluster (e.g., from 2 to 100, from 2 to 10, or from 10 to 100, nodes in a cluster). The large clusters may comprise at least 101, 250, 500, 750, 1000, 5000, or 10000 nodes. The large clusters may comprise any number of nodes between the aforementioned nodes (e.g., from 101 to 10000, from 101 to 1000, or from 1000 to 10000, nodes in a large cluster). Whether one or more than one master node assignment is being made, it may be beneficial in some examples to handle possible contention between nodes for obtaining status as a master. In some embodiments, an observer agent that broadcasts a claim to be a master continues to monitor for other such claims (coming through the communication network) for a given time. The observer agent may continue to broadcast its claim to be a master during the wait time. When no other contention is detected, the node broadcasting its claim to be a master may assume the master role. When contention by another node is detected, a contest procedure may initiate. The contest procedure may comprise an initiation of another round of broadcasting of claims to be a master node. During the new round, to reduce the likelihood of ongoing contentions the contending nodes may wait random wait times before broadcasting their claim to be a master node. The first node to place a claim for the master node on the network may assume the master role.
In the event that no master node responded at block 1002, the observer agent broadcasts a claim to assume the master role at block 1005. At block 1006, the observer agent monitors for broadcasts from any other node that may also assert a claim to the master role (i.e., a contending claim). If no contention is detected, then a check is performed in block 1007 to determine whether a contention phase is complete. Completion of the contention phase may, for example, be comprised of the expiration of a predetermined time. If the phase is complete, then the assertion of the master role is successful in block 1008. The master node initializes the cluster in block 1010. If the phase is not complete, then the claim as a master is repeated in block 1005. If a contending claim is detected at block 1006, then the observer agent broadcasts a message (e.g., a negative acknowledgement). The message informs the other nodes that the contention has occurred. Broadcasting of the contention message cancels all pending assertions to become a master node. After waiting a random amount of time in block 1012, the observer agent returns to block 1001 to broadcast a new query for an existing master. Since each of the formerly contending nodes waits a different random time to continue, it is likely that the claims to obtain the master role will not recur at the same time. One of the observer agents will have randomly a shortest wait time, allowing it to first establish a master role as a response to the query (e.g., of block 1001). The query can be broadcasted by at least one node in the network (e.g., when the node does not find a master).
In some embodiments, more than one node is designated as a master node. When there is more than one master, one of the masters may be designated as an alpha or first master. The masters may operate in a coordinated manner to share responsibilities of the master role. In another example, the alpha master can carry the sole responsibility with the other masters acting as backups. A cardinality (i.e., number of nodes) for each role (e.g., master and worker) may be determined and used by a master node when forming and configuring the cluster. A master node may check to determine whether it is the first (alpha) master. When it finds that it is the first master, then the node may apply the deployment specification (e.g., commissions the other nodes according to the roles/functions defined in the deployment specification). If not the first master node, then the node continues to operate as a master node without applying the deployment document. The master node may control work orders to working nodes (e.g., substance, execution, and/or flow of the work orders).
In some embodiments, additional new nodes are connected to an existing cluster after initial commissioning and normal orchestration operation is established. For example, a new node can be permitted to join the cluster and to receive a corresponding role as required and/or permitted by the cluster. When the new node is communicatively linked to the cluster (e.g., and when it is powered up), its observer agent may boot up and generate a join request. An existing master node may receive the join request and may determine whether the new node should be added as a worker node or as another master node. In some embodiments, there may be at most 1, 3, 5, 7, or 9 master nodes. For example, when a total number of nodes in a cluster is or becomes greater than a threshold number (e.g., five), then any number of nodes below the threshold number of nodes may be assigned to be master nodes. In some embodiments, a number (cardinality) of master nodes is selected to be an odd number. An odd number of master nodes facilitates resolving conflicts (e.g., breaking a tie) during a contest of nodes requesting to become a master node (e.g., a contest procedure as described herein), and/or when master nodes are sharing control of a processing system and generate conflicting actions.
In some embodiments, commissioning that occurs when adding a new node includes assignment of a worker node to an existing master node, assignment of a worker node to a particular client (e.g., a device such as an IGU), and/or assignment of a (e.g., additional) master node. Nodes can, for example, be added in a plug and play fashion, resulting in automated horizontal scaling.
In some embodiments, assignments of a role to one or more nodes occurs during initial installation, upon addition of new nodes, and/or upon departure (e.g., failure or removal) of one or more nodes from a cluster. For example, an observer agent in a master node or a worker node can monitor activity of other nodes. The observer agent can infer malfunctioning of a node that remains silent for a predetermined time and/or that fails to respond to direct queries. By automatically reassigning roles upon detection of a failure, the resiliency of the processing system is improved, e.g., since occurrence of a single point of failure can be reduced (e.g., avoided). A master node (e.g., a supervisory node) can be assigned, replaced (e.g., switched), or the numbers of master nodes increased, such as for resiliency purpose. In some embodiments, the assignment and/or selection of nodes is done using a stochastic model. In some embodiments, a manual override is used to replace a stochastic distribution (e.g., for supervisor assignment). In some embodiments, the initial setup of the nodes is stochastic, while reassignment of masters is non-stochastic. In some embodiments, the initial setup of the nodes is non-stochastic, while reassignment of masters is stochastic. In some embodiments, when a worker node realizes it has no master (e.g., when the cluster loses at least one master), then a new master is assigned. In one example, the worker node first detecting the loss of a master can become the new master. In an example, the worker node in a cluster can ask for a new master to be assigned from other available masters in the cluster. In an example, a master can be temporarily assigned from the cloud. In an example, the worker node may function without a master temporarily (e.g., for a limited time, that can be pre-determined) while the overall system assigns and/or requests another master assignment. The processing system may have redundancy (e.g., of supervisor nodes and/or of worker nodes). The processing system can have backup master nodes, e.g. worker nodes with instructions to become master nodes upon at least one triggering event. A triggering event can comprise a master leaving the system due to malfunction, maintenance, or increase in the cluster complexity (e.g., as disclosed herein). The processing system can be fully or partially redundant. For example, the system may have at least partial master node redundancy. For example, the system may have at least partial worker node redundancy. The system may have redundancy depending on the importance (i) of a facility or any section (e.g., rooms) thereof, and/or (ii) of network section(s).
In some embodiments, a voting method may be used to resolve a contest of nodes. (e.g., to conduct a contest procedure). In some embodiments, the master role is assigned according to a voting method. The voting method could be invoked in a cluster during initial boot-up. The voting method could be invoked in a cluster when nodes leave and/or joins a cluster having one or more existing master node assignments. For example, when there is one master node and an additional node joins a cluster, the cardinality can be checked to determine whether a threshold is reached. Reaching the threshold may trigger allowance (e.g., and subsequent formation of) a greater number of master nodes. When it is determined that a master node should be added, then a voting process may be utilized. The voting process may include a solicitation message, e.g., that is broadcasted (e.g., by the observer agent in the master node) to the nodes in the cluster. Each node may be programmed to respond to a solicitation message, e.g., when a (e.g., predetermined) processing capacity is available on the node. If a number of nodes respond than are needed, which number of nodes is greater than the threshold, then the master node may make a selection. The selection may be done randomly. The selection may be using criteria such as type of node or processing capacity. The selection may employ any selection criteria and/or scheme disclosed herein, e.g., any scheduling and/or organizational scheme.
In some embodiments, the observer agents are in continuous operation in order to maintain appropriate numbers of master nodes and to adjust when nodes join or leave a cluster. In one example, adjustment of roles to ensure sufficient numbers of master nodes may be triggered by a segregation of an existing cluster into two or more different clusters. For example, occupancy in a building or portion of a building formerly occupied by one customer may be subdivided so that a portion becomes occupied by a different customer. For example, the number of clients (e.g., devices) supported by a cluster increases a size that the cluster can (e.g., reliably) handle. The local network link may be severed at a point that isolates separate the cluster to sub clusters. The separation of the cluster to sub clusters may be according to the spaces occupied by the different customers. This may be conducted for the purpose of maintaining security and/or confidentiality between the different customers. The separation of the cluster to sub clusters may be according to the complexity of the cluster (e.g., when clients and/or node numbers increase beyond a threshold). This may be conducted for the purpose of maintaining reliable and/or safe operation of the cluster. A safe operation may be execution of cluster operation (e.g., control) without collapse of the cluster. A safe operation may depend on jurisdictional requirements (e.g., ensuring health and safety of occupants in the facility). In response to dividing the cluster into sub clusters, the observer agents may (e.g., automatically) adjust roles within each sub cluster as necessary.

In some embodiments, a client comprises a device. The device may be controlled by the processing system. The device may include a tintable window in an insulated glass unit (“IGU”). The terms “IGU,” “tintable window,” and “optically switchable window” can be used interchangeably herein. It can be desirable to have IGUs serve as the fundamental constructs for holding electrochromic panes (also referred to herein as “lites”) when provided for installation in a building. An IGU lite may be a single substrate or a multi-substrate construct. The lite may comprise a laminate, e.g., of two substrates. IGUs (e.g., having double- or triple-pane configurations) can provide a number of advantages over single pane configurations. For example, multi-pane configurations can provide enhanced thermal insulation, noise insulation, environmental protection and/or durability, when compared with single-pane configurations. A multi-pane configuration can provide increased protection for an ECD. For example, the electrochromic films (e.g., as well as associated layers and conductive interconnects) can be formed on an interior surface of the multi-pane IGU and be protected by an inert gas fill in the interior volume of the IGU. The inert gas fill may provide at least some (heat) insulating function for an IGU. Electrochromic IGUs may have heat blocking capability, e.g., by virtue of a tintable coating that absorbs (and/or reflects) heat and light.
In some embodiments, an “IGU” includes two (or more) substantially transparent substrates. For example, the IGU may include two panes of glass. At least one substrate of the IGU can include an electrochromic device disposed thereon. The one or more panes of the IGU may have a separator disposed between them. An IGU can be a hermetically sealed construct, e.g., having an interior region that is isolated from the ambient environment. A “window assembly” may include an IGU. A “window assembly” may include a (e.g., stand-alone) laminate. A “window assembly” may include one or more electrical leads, e.g., for connecting the IGUs and/or laminates. The electrical leads may operatively couple (e.g. connect) one or more electrochromic devices to a voltage source, switches and the like, and may include a frame that supports the IGU or laminate. A window assembly may include a window controller, and/or components of a window controller (e.g., a dock).
In some implementations, the first and the second panes are transparent or translucent, e.g., at least to light in the visible spectrum. For example, the first pane and/or second can comprise a hardened material that is at least partially transparent in the visual spectrum. The hardened material may be a polymer or a resin. The hardened material may be an organic polymer. The hardened material may be glass. For example, the first pane and/or second pane (e.g., lite) can be formed of a glass material. The glass material may include architectural glass, and/or shatter-resistant glass. The glass may comprise a silicon oxide (SOx). The glass may comprise a soda-lime glass or float glass. The glass may comprise at least about 75% silica (SiO2). The glass may comprise oxides such as Na2O, or CaO. The glass may comprise alkali or alkali-earth oxides. The glass may comprise one or more additives. The first and/or the second panes can include any material having suitable optical, electrical, thermal, and/or mechanical properties. Other materials (e.g., substrates) that can be included in the first and/or the second panes are plastic, semi-plastic and/or thermoplastic materials, for example, poly(methyl methacrylate), polystyrene, polycarbonate, allyl diglycol carbonate, SAN (styrene acrylonitrile copolymer), poly(4-methyl-1-pentene), polyester, and/or polyamide. The first and/or second pane may include mirror material (e.g., silver). In some implementations, the first and/or the second panes can be strengthened. The strengthening may include tempering, heating, and/or chemically strengthening.
In various embodiments, a network infrastructure supports a control system for one or more windows such as electrochromic (e.g., tintable) windows. The control system may comprise one or more controllers operatively coupled (e.g., directly or indirectly) to one or more windows. While the disclosed embodiments describe electrochromic windows (also referred to herein as “optically switchable windows,” “tintable windows”, or “smart windows”), the concepts disclosed herein may apply to other types of switchable optical devices including, for example, a liquid crystal device, or a suspended particle device. For example, a liquid crystal device and/or a suspended particle device may be implemented instead of, or in addition to, an electrochromic device.
In various embodiments, a network infrastructure supports a control system for one or more windows such as tintable (e.g., electrochromic) windows. The control system may comprise one or more controllers operatively coupled (e.g., directly or indirectly) to one or more windows. While the disclosed embodiments describe tintable windows (also referred to herein as “optically switchable windows,” or “smart windows”) such as electrochromic windows, the concepts disclosed herein may apply to other types of switchable optical devices comprising a liquid crystal device, an electrochromic device, suspended particle device (SPD), NanoChromics display (NCD), Organic electroluminescent display (OELD), suspended particle device (SPD), NanoChromics display (NCD), or an Organic electroluminescent display (OELD). The display element may be attached to a part of a transparent body (such as the windows). The tintable window may be disposed in a (non-transitory) facility such as a building, and/or in a transitory facility (e.g., vehicle) such as a car, RV, bus, train, airplane, helicopter, ship, or boat.
In some embodiments, a tintable window exhibits a (e.g., controllable and/or reversible) change in at least one optical property of the window, e.g., when a stimulus is applied. The change may be a continuous change. A change may be to discrete tint levels (e.g., to at least about 2, 4, 8, 16, or 32 tint levels). The optical property may comprise hue, or transmissivity. The hue may comprise color. The transmissivity may be of one or more wavelengths. The wavelengths may comprise ultraviolet, visible, or infrared wavelengths. The stimulus can include an optical, electrical and/or magnetic stimulus. For example, the stimulus can include an applied voltage and/or current. One or more tintable windows can be used to control lighting and/or glare conditions, e.g., by regulating the transmission of solar energy propagating through them. One or more tintable windows can be used to control a temperature within a building, e.g., by regulating the transmission of solar energy propagating through the window. Control of the solar energy may control heat load imposed on the interior of the facility (e.g., building). The control may be manual and/or automatic. The control may be used for maintaining one or more requested (e.g., environmental) conditions, e.g., occupant comfort. The control may include reducing energy consumption of a heating, ventilation, air conditioning and/or lighting systems. At least two of heating, ventilation, and air conditioning may be induced by separate systems. At least two of heating, ventilation, and air conditioning may be induced by one system. The heating, ventilation, and air conditioning may be induced by a single system (abbreviated herein as “HVAC”). In some cases, tintable windows may be responsive to (e.g., and communicatively coupled to) one or more environmental sensors and/or user control. Tintable windows may comprise (e.g., may be) electrochromic windows. The windows may be located in the range from the interior to the exterior of a structure (e.g., facility, e.g., building). However, this need not be the case. Tintable windows may operate using liquid crystal devices, suspended particle devices, microelectromechanical systems (MEMS) devices (such as microshutters), or any technology known now, or later developed, that is configured to control light transmission through a window. Windows (e.g., with MEMS devices for tinting) are described in U.S. Pat. No. 10,359,681, issued Jul. 23, 2019, filed May 15, 2015, titled “MULTI-PANE WINDOWS INCLUDING ELECTROCHROMIC DEVICES AND ELECTROMECHANICAL SYSTEMS DEVICES,” and incorporated herein by reference in its entirety. In some cases, one or more tintable windows can be located within the interior of a building, e.g., between a conference room and a hallway. In some cases, one or more tintable windows can be used in automobiles, trains, aircraft, and other vehicles, e.g., in lieu of a passive and/or non-tinting window.
In some embodiments, the tintable window comprises an electrochromic device (referred to herein as an “EC device” (abbreviated herein as ECD, or “EC” device). An EC device may comprise at least one coating that includes at least one layer. The at least one layer can comprise an electrochromic material. In some embodiments, the electrochromic material exhibits a change from one optical state to another, e.g., when an electric potential is applied across the EC device. The transition of the electrochromic layer from one optical state to another optical state can be caused, e.g., by reversible, semi-reversible, or irreversible ion insertion into the electrochromic material (e.g., by way of intercalation) and a corresponding injection of charge-balancing electrons. For example, the transition of the electrochromic layer from one optical state to another optical state can be caused, e.g., by a reversible ion insertion into the electrochromic material (e.g., by way of intercalation) and a corresponding injection of charge-balancing electrons. Reversible may be for the expected lifetime of the ECD. Semi-reversible refers to a measurable (e.g., noticeable) degradation in the reversibility of the tint of the window over one or more tinting cycles. In some instances, a fraction of the ions responsible for the optical transition is irreversibly bound up in the electrochromic material (e.g., and thus the induced (altered) tint state of the window is not reversible to its original tinting state). In various EC devices, at least some (e.g., all) of the irreversibly bound ions can be used to compensate for “blind charge” in the material (e.g., ECD)
In some implementations, suitable ions include cations. The cations may include lithium ions (Li+) and/or hydrogen ions (H+) (i.e., protons). In some implementations, other ions can be suitable. Intercalation of the cations may be into an (e.g., metal) oxide. A change in the intercalation state of the ions (e.g. cations) into the oxide may induce a visible change in a tint (e.g., color) of the oxide. For example, the oxide may transition from a colorless to a colored state. For example, intercalation of lithium ions into tungsten oxide (WO3-y (0<y≤˜0.3)) may cause the tungsten oxide to change from a transparent state to a colored (e.g., blue) state. EC device coatings as described herein are located within the viewable portion of the tintable window such that the tinting of the EC device coating can be used to control the optical state of the tintable window.
A voltage source may be operably connected to apply an electric potential across the electrochromic stack 1803 to effect transitions of the electrochromic coating from, e.g., a clear state to a tinted state. In other embodiments, the order of layers is reversed with respect to the substrate. That is, the layers can be in the following order: substrate, TCL, counter electrode layer, ion conducting layer, electrochromic material layer, TCL.
In some embodiments, the ion conductor region forms from a portion of the EC layer and/or from a portion of the CE layer. The electrochromic stack may be deposited to include cathodically coloring electrochromic material (the EC layer) in direct physical contact with an anodically coloring counter electrode material (the CE layer). The ion conductor region (sometimes referred to as an interfacial region, or as an ion conducting substantially electronically insulating layer or region) may form where the EC layer and the CE layer meet, for example through heating and/or other processing steps. Examples of electrochromic devices (e.g., including those fabricated without depositing a distinct ion conductor material) can be found in U.S. patent application Ser. No. 13/462,725 filed May 2, 2012, titled “ELECTROCHROMIC DEVICES,” that is incorporated herein by reference in its entirety. In some embodiments, an EC device coating may include one or more additional layers such as one or more passive layers. Passive layers can be used to improve certain optical properties, to provide moisture, and/or to provide scratch resistance. These and/or other passive layers can serve to hermetically seal the EC stack 1803. Various layers, including transparent conducting layers (such as 1801 and 1802), can be treated with anti-reflective and/or protective layers (e.g., oxide and/or nitride layers).
In certain embodiments, the electrochromic device is configured to (e.g., substantially) reversibly cycle between a clear state and a tinted state. Reversible may be within an expected lifetime of the ECD. The expected lifetime can be at least about 5, 10, 15, 25, 50, 75, or 100 years. The expected lifetime can be any value between the aforementioned values (e.g., from about 5 years to about 100 years, from about 5 years to about 50 years, or from about 50 years to about 100 years). A potential can be applied to the electrochromic stack such that available ions in the stack that can cause the electrochromic material to be in the tinted state reside primarily in the counter electrode when the window is in a first tint state (e.g., clear). When the potential applied to the electrochromic stack is reversed, the ions can be transported across the ion conducting layer to the electrochromic material and cause the material to enter the second tint state (e.g., tinted state).
It should be understood that the reference to a transition between a clear state and tinted state is non-limiting and suggests only one example, among many, of an electrochromic transition that may be implemented. Unless otherwise specified herein, whenever reference is made to a clear-tinted transition, the corresponding device or process encompasses other optical state transitions such as non-reflective-reflective, and/or transparent-opaque. In some embodiments, the terms “clear” and “bleached” refer to an optically neutral state, e.g., untinted, transparent and/or translucent. In some embodiments, the “color” or “tint” of an electrochromic transition is not limited to any wavelength or range of wavelengths. The choice of appropriate electrochromic material and counter electrode materials may govern the relevant optical transition (e.g., from tinted to untinted state).
In certain embodiments, at least a portion (e.g., all of) the materials making up electrochromic stack are inorganic, solid (i.e., in the solid state), or both inorganic and solid. Because various organic materials tend to degrade over time, particularly when exposed to heat and UV light as tinted building windows are, inorganic materials offer an advantage of a reliable electrochromic stack that can function for extended periods of time. In some embodiments, materials in the solid state can offer the advantage of being minimally contaminated and minimizing leakage issues, as materials in the liquid state sometimes do. One or more of the layers in the stack may contain some amount of organic material (e.g., that is measurable). The ECD or any portion thereof (e.g., one or more of the layers) may contain little or no measurable organic matter. The ECD or any portion thereof (e.g., one or more of the layers) may contain one or more liquids that may be present in little amounts. Little may be of at most about 100 ppm, 10 ppm, or 1 ppm of the ECD.
