Many casement window operating assemblies utilize a rotary actuator that may be used to open or close a window sash. The actuator is typically in the form of a hand crank adapted to be turned in one direction to open the sash and in an opposite direction to close the sash. There are also instances where the actuator is operable by an electric motor.
There have been many types of actuators that have been utilized in the past. However, there has always been room for improvement and changes over control of window operating assemblies.

Embodiments of the disclosure are directed to a window operator assembly interconnecting a window assembly including a window frame and a sash of a window. The sash is pivotally mounted to the frame. The window operator assembly may include a motor, communication circuitry, and processor circuitry. The motor may be coupled to an elongate member and causes the elongate member to move, thereby changing a position of the sash, such as moving the window to an open position, a closed position, or any position between. The communication circuitry is configured to provide a first type and a second type of wireless communications with a first wireless communication system and a second wireless communication system. The processor circuitry may identify connection loss between the communication circuitry and the first wireless communication system, and in response, cause the communication circuitry to switch to the second wireless communication system and cause the window operator assembly to perform an action, such as activating the motor to move the window to a closed position. The use of multiple types of wireless communication and triggering automatic action by the window operator assembly in response to connection loss may increase security and improve user functionality for a window assembly that operates using wireless communications.

As further described below, in some embodiments, a single user input may cause multiple actions by the window operator assembly, such as locking or unlocking a lock and moving the window to a closed or open position. Further, the user can provide the user input and the window automatically moves position(s) without further user action.
Various embodiments are directed to systems which include the window operator assembly and other devices. In some embodiments, a system comprises the above-described window operator assembly, local computing device, and remotely-located computing device. In other embodiments and/or in addition, a system may include a plurality of wireless communication devices that communicate over a local network via a first wireless communication system, with the plurality wireless communication devices including at least one window operator assembly and at least one local computing device.

Turning now to the figures,
The window operator assembly 100 includes a motor 102, communication circuitry 104, and processor circuitry 106. The window operator assembly 100 may be used to control the window assembly 108, including changing positions of the window, via the processor circuitry 106 and the motor 102. The window assembly 108 may include a window in a window frame, with the sash pivotally mounted to the window frame and coupled to the elongate member, as further shown by
The window operator assembly 100 may communicate with other devices using different types of wireless communications. For example, the communication circuitry 104 may provide a first type of wireless communication 105 and a second type of wireless communication 107 with a first wireless communication system and a second wireless communication system. The first type of wireless communication 105 may be associated with a longer range than the second type of wireless communication 107. For example, the first type of wireless communication 105 may include Wi-Fi and the second type of wireless communication 107 may include Bluetooth. The communication circuitry 104 may wirelessly communicate data using telemetry components according to wireless protocols associated with the first and second wireless communication systems. In various embodiments, the wireless communication using the first and second wireless communication systems may both be encrypted. Example telemetry components include a transmitter, a receiver, or a combination transceiver, and an antenna (e.g., inductive telemetry antenna).
The processor circuitry 106 is configured to activate the motor 102 to move the window to a position and at a set speed based on communication from external circuitry, such as via communication from the wireless communication device 109 and using the communication circuitry 104. In some embodiments, the processor circuitry 106 may control a set speed of the movement of the window based on pulse width modulation (PWM) of the motor 102. In some embodiments, a motor encoder 112 may be coupled to the motor 102 to provide feedback data to the processor circuitry 106 used to adjust the PWM, as further described below. As further described below, processor circuitry 106 includes and/or refers to a presently developed or future developed processor (or processing resources) that executes computer readable instructions contained in memory. The processor circuitry 106 may be used to switch between the first and second wireless communication systems. For example, the processor circuitry 106 may identify connection loss between the communication circuitry 104 and the first wireless communication system, and in response, cause the communication circuitry 104 to switch to the second wireless communication system and cause the window operator assembly 100 to perform an action.
A variety of different actions may be performed by the window operator assembly 100 in response to switching to the second wireless communication system. In some embodiments, the processor circuitry 106 may activate the motor 102 to move the window of the window assembly 108 (connected to the window operator assembly 100) to a closed position in response to the connection loss. The processor circuitry 106 may do so automatically, to provide a safety feature such that window(s) in a building (e.g., a home) automatically close when a first wireless communication (e.g., a Wi-Fi signal) is lost. In some embodiments, the processor circuitry 106 may cause the window of the window assembly 108 to lock in the closed position, in response to the connection loss. In some embodiments, the processor circuitry 106 may cause the communication circuitry 104 to communicate a message using the second type of wireless communications to the wireless communication device 109, which may be associated with a user. The message may be indicative of the lost connection and/or notify a user associated with the window assembly 108 that the window is moving to a closed position, is in the closed position, and/or is being locked in response to the lost connection. In some embodiments, the message may provide a prompt for the user to verify the window is to be placed in the closed position and/or approval to leave or reposition the window back to an open position that the window was in prior to the lost connection.
In some embodiments, the processor circuitry 106 may verify the wireless communication device 109 is an approved device connected to the second wireless communication system and/or is within a threshold range of the window operator assembly 100. For example, the processor circuitry 106 can verify the wireless communication device 109 is a Bluetooth connected device within the threshold range, and optionally in response, may override closing the window of the window assembly 108. In some embodiments, various combinations of the above actions may be initiated by the processor circuitry 106 in response to the connection loss.
In some embodiments, the processor circuitry 106 may cause the communication circuitry 104 to switch to the second wireless communication system 107 and to connect to a third wireless communication system associated with the first type of wireless communication 105. For example, a user may switch to a new Wi-Fi system. In response to connection loss with the first Wi-Fi system, the processor circuitry 106 may cause the communication circuitry 104 to switch to Bluetooth, which is used by the user to subsequently connect the communication circuitry 104 to the new Wi-Fi system. As further described below, the window operator assembly 100 may have a window ID that is registered to associate the window operator assembly 100 and the coupled window assembly 108 to a building. Non-limiting examples of buildings include a house, a townhouse, an apartment building and/or an apartment, a condominium building and/or condominium, an office building, a commercial store building, a factory, a school and/or college building, a daycare center, among other commercial, retail, and/or residential buildings. A plurality of windows in the building may have similar window operator assemblies as the window operator assembly 100 and are registered to the building ID and connected to the first wireless communication system. By changing the wireless communication setting for the window operator assembly 100 to the third wireless communication system, all window IDs associated with the building ID may be automatically updated to communicate using the third wireless communication system.
In some embodiments, switching to the second wireless communication system may allow for communication with the window operator assembly 100 and control over the window assembly 108 to be maintained even with the lost connection with the first wireless communication system. Maintaining the communication may be useful for security purposes. Performing the action(s) may provide for additional security by closing window(s) in a building in response to loss of the first (primary) type of wireless communication. In some embodiments, setup of the window occurs in the second wireless communication system (e.g., Bluetooth) as wireless communication allows for easier initial communication and provides a way to assign the information associated with the first wireless communication system (e.g., WiFi) for ongoing communications. As an example, Bluetooth is good for nearby, direct control when internet access is not available. Some of the example first and second wireless communication systems have existed for a long period of time and changes to the standards associated therewith occur in increments, which allows for longer term methods to communicate as technology changes.
As noted above, a motor encoder may be coupled to the motor 102. A motor encoder, as used herein, is an electromechanical device that provides an electrical signal indicative of the motor turning. For example, the motor encoder 112 may include a circuit board with a magnet attached to the motor shaft of the motor 102. Each time the motor 102 turns, the circuit board may count a number of magnetic pulses (e.g., seven pulses per motor turn) using the magnet as encoder counts, and based on the encoder counts, the processor circuitry 106 and/or motor encoder 112 may determine the position of the window. The motor encoder 112 may provide the encoder counts as feedback data to the processor circuitry 106. For example, as further described below, based on a configuration of the window operator assembly 100 and/or a self-zeroing process, positions of the window may be determined using the encoder counts. In some embodiments, as the window is at or near the open or closed positions, the motor 102 may slow down or stop, which may be identified using the feedback data.
In some embodiments, the encoder count may be used to keep the motor 102 at a constant speed, sometimes referred to as “cruise control”. For example, feedback data from the motor encoder 112 may be provided to the processor circuitry 106 and the processor circuitry 106 may determine the encoder counts are coming it at a slower rate than before. In response, the processor circuitry 106 increases the PWM (e.g., voltage) to the motor 102 to keep the motor 102 at the same or constant speed.
Control of the window assembly 108 may be provided using additional security features. For example, the processor circuitry 106 may encrypt the first type and second type of wireless communications over the wireless communication systems 105, 107 prior to the communication circuitry 104 communicating with other devices. Similarly, the processor circuitry 106 can decrypt and authenticate communications from other devices.
In some embodiments, the window operator assembly 100 includes a portion containing an ID. For example, the portion may include an ID tag 101. The ID tag 101 may be scanned by the wireless communication device 109 to provide the window ID. For security purposes, the ID tag 101 may include a near field communication (NFC) tag, however examples are not so limited and may include other types of tags or other sources that may be scanned to provide a window ID, such as a QR code, and a bar code, among others. The ID tag 101 or other portion of the window operator assembly 100 may be scanned in order to associate the window ID with a building, as further described herein.
In some embodiments, the ID tag 101 may be used as an added security for switching to a different communication system for a building. For example, prior to changing the wireless communication setting for all window operators assemblies (e.g., window IDs) of a building, one ID tag 101 of the window operator assemblies may be scanned and then used to bulk update the wireless communications setting for all windows of the building.
In some embodiments, the window operator assembly 100 may include or be coupled to one or more sensors 103. The one or more sensors 103 may include a pressure sensor, a liquid sensor, a glass break sensor, a motion sensor, a magnetic sensor, and various combinations thereof.
In some embodiments, the window operator assembly 100 includes or is coupled to a pressure sensor that communicates with the processor circuitry 106. The processor circuitry 106 may stop movement of the window in response to a sensor signal from the pressure sensor indicating the movement is slower than a threshold speed. In some embodiments, the sensor includes the motor encoder 112 and the movement being slower than the threshold speed may be determined using feedback data from the motor encoder 112 coupled to the motor 102.
In some embodiments, the window operator assembly 100 includes or is coupled to a liquid sensor that communicates with the processor circuitry 106. The processor circuitry 106 may close the window in response to a sensor signal from the liquid sensor indicating occurrence of rain or other sources of liquid (e.g., sprinkler, water leak in the building).
In some embodiments, the window operator assembly 100 includes or is coupled to a glass break sensor that communicates with the processor circuitry 106. The processor circuitry 106 may communicate an alert, via the communication circuitry 104 and to external circuitry, in response a sensor signal from the glass break sensor indicating the window is being broken. The external circuitry, as used herein, may include the wireless communication device 109 or another device. In some embodiments, the glass break sensor may include a wireless sensor that detects the glass of the window being broken, and in response, sends a wireless signal over the cloud to the external circuitry. In some embodiments, the wireless signal may cause control of operation of the window operator assembly 100 by an application being run by the wireless communication device 109 and/or over a cloud computing system.
In some embodiments, the window operator assembly 100 includes or is coupled to a motion sensor that communicates with the processor circuitry 106. The processor circuitry 106 may communicate an alert, via the communication circuitry 104 and to external circuitry, in response a sensor signal from the motion sensor indicating the window is being manually moved.
In various embodiments, the window operator assembly 100 further includes lock motor assembly including a motor, a lock, and lock controller circuitry 113. The lock may include a lock bar and keepers, with the lock bar being located in or forming part of the window frame of the window assembly 108 and the keepers being located in or forming part of the sash of the window assembly 108. The lock motor assembly moves the lock bar to engage and disengage the keepers on the sash, such that the lock bar may slideably attach to the frame and to engage and disengage the keepers. The lock controller circuitry may include a processor circuitry (which may include an additional processor circuitry or the processor circuitry 106) that provides power and control to the motor. The lock may be positioned in a locked position or unlocked position. The locked position of the lock includes the lock bar being engaged with and locked in with the keepers. The unlocked position includes bar being unengaged with the keepers.
As the window is moving from an open position to a closed position, the lock bar is moved to activate the lock and, in response, hits the gasket such that there is an increase in force on the lock bar. The keepers then move the sash into the fully closed and locked position by moving the sash further against the gasket to compress the gasket in the fully closed and locked positon. In some embodiments, the motor of the lock motor assembly includes another motor encoder, which provides an encoder count indicative of motor movement and changes in speed to the processor circuitry as feedback data. The processor circuitry uses the same to detect the speed of the motor of the lock motor assembly and to increase or decrease the PWM (e.g., voltage) to the motor to keep the speed constant or at the same level.
In some embodiments, the window operator assembly 100 includes or is coupled to a magnetic sensor that communicates with the processor circuitry 106 and a magnet. The processor circuitry 106 may identify the window is unlocked or locked based on sensor signals from the magnetic sensor and from the magnetic sensor interacting with the magnet. The magnet and magnetic sensor may be used to determine or signal that the window is a in a closed position, and may not directed sense whether the lock is unlocked or locked. In various embodiments, there is correlation between the window position and the lock position, as the window position changes slightly between the locked and unlocked position of the lock. The magnet and sensor (e.g., Hall sensor) may detect this change in window position caused by the lock moving from an unlocked position to a locked position while the window is the closed position. However, embodiments are not so limited, and the processor circuitry 106 may determine the window is locked or unlocked based on the set position of the lock and without use of a sensor.
In some embodiments, the magnetic sensor is used to detect the window is in or near a closed position and/or an open position. For example, a magnet may be located on the sash and the magnetic sensor may be located on the window frame. In response to the window frame being within a threshold distance of the sash (e.g., one to 1.5 inches away), the magnetic sensor may detect a magnetic field from the magnet. As the sash gets closer, the magnetic field gets stronger. As may be appreciated, each magnet may be different (e.g., exhibits different strength magnetic fields) and the magnetic sensors may be located differently in the window frame, resulting in different signal strengths from the different magnetic sensors when the windows are at or near the closed positions between different windows. In some embodiments, the magnetic sensor can be calibrated during a setup and/or self-zeroing process, as further described below.
One or both of top and bottom window operator assemblies may be used. For larger windows, using both the top window operator assembly and the bottom window operator assembly adds strength and stability to the system and makes it easier to open and close the sash. For smaller windows, the window operator assembly 200 may be positioned on either the top member (not shown) or the bottom member 213 of the window frame 221.
Embodiments may include at least one motor. There may be a motor proximate the top and/or the bottom of the window frame 221 and there may be more than one motor proximate the top and/or the bottom of the window frame 221. The motor(s) may allow for operation of the assembly utilizing a variety of actuating sources such as, but not limited to, a wall switch, a remote control, a mobile phone app, a home security system, a heating, ventilation, and air conditioning (HVAC system), and other types of home automation systems. If there is a loss of power to the system, there may be a manual override.
The window operator assembly 200 includes a housing 223. In this embodiment, the housing 223 is configured and arranged to contain at least portions of the window operator assembly 200 including the motor, communication circuitry, and processor circuitry as described by
In use, the motor causes the elongated member (not illustrated), which is housed by the elongate housing 222 to move, and the sash 217 pivots about the sash pivot 226 and moves toward its closed position.
The computer-readable storage medium 334 (as well as the computer-readable storage medium 444 illustrated by
At 336, the processor circuitry 332 may receive a window ID associated with a window operator assembly and a building ID associated with a building containing a window connected to the window operator assembly. The window operator assembly may include or be implemented to include substantially the same features as the window operator assembly 100 of
At 338, the processor circuitry 332 assigns the window ID to the building ID. The processor circuitry 332 may store the assignment in a database that includes a plurality of window IDs associated with respective building IDs. The database may further include sets of rules for controlling changes to the assignments, which may be different for different building IDs.
At 339, the processor circuitry 332 controls changes to the assignment of the window ID to the building ID based on a set of rules. The set of rules may be associated with a number of buildings a window ID is permitted to be assigned to, limits to changes to the assignment of the window ID to the building ID, user ID permissions to control the window, and a time limit for a user ID permission (e.g., permitted) to control the window ID. In some embodiments, a window ID may be permitted to be assigned to one building (e.g., building ID) only, and there may be limits to changes to the assignment without user authorized release or a threshold amount of time. In some embodiments, different users with associated user IDs may be given permission to control the window and which may be associated with a time limit for the control, such as providing time-limited permission to a renter (e.g., Airbnb), a contractor performing work, or for other purposes. As further described below, the window operator assembly may form part of an IOT system with other devices in the building, and the time-limited permission may be granted for any device that is part of the IOT system, such as HVAC or security system and with the owner of the building or other user associated with the building ID have override authority. Changes to authorized control of the window may be restricted by the set of rules and by the processor circuitry 332, which may be in communication with local computing devices (e.g., smartphones, laptop computers) running applications to instruct respective window operator assemblies associated with a building ID. For example, the processor circuitry 332 may prevent the window ID from being reassigned to a different building ID or being removed from the building ID, such as based on the set of rules.
In some embodiments, the processor circuitry 332 communicates updates to the window operator assembly (e.g., push updates). The communication may be provided directly from the computing device 330 to the window operator assembly or to a computing device that is locally located with respect to the window operator assembly, sometimes herein referred to as “a local computing device”, that provides the update to the window operator assembly. For example, the processor circuitry 332 may push an update to all window operator assemblies associated with a building ID by communicating with each window operator assembly or with the local computing device.
Similarly and/or which may be included as an update, the processor circuitry 332 may communicate a plurality of use rules to the local computing device. The local computing device may include a wireless communication device, such as smartphone as previously described. Example use rules include rules associated with or directing a window operator assembly to: i) close and lock window(s) associated with a building ID in response to connection loss with a first wireless communication system (e.g., Wi-Fi); ii) switch to communicating a second type of wireless communications using a second wireless communication system (e.g., Bluetooth) in response to connection lost with the first wireless communication system (e.g., Wi-Fi); and iii) close and lock the window(s) in response to use of the second wireless communication system (e.g., Bluetooth) and an approved wireless communication device being out of range.
As described above, the processor 332 and computer-readable storage medium 334 may form part of computing device 330 that is a remotely-located computing device, or part of a computing device that is local to the window operator assembly, such as a local server or computer of a building e.g., a local computing device. In some examples, the computing device 330 forms part of a cloud computing system having a plurality of remotely-located and/or distributed computing devices. For example, although
In some embodiments, the computing device 440 may be used to register and control operations of window operator assemblies of a building, as shown by
As shown by
In some embodiments, a single user input to the GUI may cause multiple actions by the window operator assembly. For example, the single user input to the adjustable icon may cause the lock of the window to move to an unlocked position and cause the window to move from a closed position to an open positon. As another example, the single user input to the adjustable icon may cause the window to move from an open position to a closed positon and the lock of the window to move to a locked position.
In some embodiments, the GUI may further include a speed control icon. For example, in response to the user input or a second user input to the GUI associated with the speed control icon, the processor circuitry 442 may wirelessly communicate the message to cause the change in the position of the window at a controlled speed based on the user input(s). Example speed control icons include a dial, a listing of speed values, images of the speeds (e.g., a rabbit for fast and turtle for slow), among others.
In some embodiments, the processor circuitry 442 may provide feedback to the user to indicate the change in the position. The feedback may include haptic feedback provided through the display, visual feedback on the GUI, and/or audio feedback (e.g., clicking sounds) provided through speakers of the computing device 440. For example, the GUI can change to illustrate the window is in the changed position. In some embodiments, the display of the adjustable icon may automatically change and display in response to the window being in the changed position. As an example, the image of the window on the GUI may be revised to show the window in the changed position (e.g., at 45 degrees open). As another example, the slide bar dial may change to a position indicative of the changed positon of the window. In some embodiments and/or in addition, the GUI may show an indication of the lock being locked or unlocked, such as words indicating the same.
Although not illustrated together, the computing device 440 may include the combination of instructions illustrated by
In some embodiments, the computing device 440 may be used to form groups of windows of the building. The groups may be used to provide simultaneous control of all windows of a group, such as setting each window of the group to a particular position regardless of a starting position. For example, the processor circuitry 442 may group the window ID with other window IDs, and communicate a message to the group to simultaneously and/or concurrently control a position of each of the associated windows. In some such embodiments, the GUI on the display of the computing device 440 may be associated with the group of windows that includes the window, and the message is wirelessly communicated to each window of the group and causes each window of the group to be in a similar position (regardless of a starting position).
In some embodiments, the processor circuitry 442 may provide a GUI indicating an alert for the user. The GUI with the alert may be in response to a communication from a window operator assembly that is indicative of a loss of connection to a first wireless communication system (e.g., Wi-Fi), an approved wireless communication (e.g., Bluetooth connected) device out of range, a window is closed and locked in response to event (e.g., Wi-Fi or Bluetooth loss, rain), an error (e.g., should perform self-zeroing), a sensor event, and a communication attempt with non-authorized devices, among other communications and combinations thereof. For example, the alert may indicate that all window operator assemblies associated with a building ID have lost a wireless connection and that an approved wireless communication device is within or is not within a range which is associated with a second type of wireless communication. The alert may additionally notify the user that all windows have moved to a closed position in response to the connection loss. In some embodiments, the GUI may provide the user with an option to override the movement of the windows and to cause all windows to move back to a position that the windows were in prior to the connection loss. In some embodiments, the override option may be provided prior to the windows moving to the closed position, such as in response the approved wireless communication device being within range and the user providing the input to override closing the windows to the approved wireless communication device (or another computing device) within a threshold amount of time from the connection loss. In some embodiments, the processor circuitry 442 may provide a revised GUI that includes the adjustable icon, which may be used to override the windows closing.
In some embodiments, the processor circuitry 442 may provide notification of an error and, in response to further user input to the GUI, wirelessly communicate another message to the window to perform a self-zeroing operation. The notification may include an alert indicating the error occurred and/or identification of a specific window of the building. The message may not be communicated until the user provides user input as a security feature, which may prevent triggering opening of the window due to a break-in attempt or other issue that causes the error, such as a minor attempting to leave the building (e.g., child safety feature). The self-zeroing operation may include the window operator assembly causing the window to move to the open position and then the closed position to fix the error. In other embodiments, the processor circuitry 442 may provide the notification of an error with the window operator assembly automatically performing the self-zeroing operation
The self-zeroing operation, in some embodiments, includes moving the window to multiple positions and obtaining measurements from motor encoder(s) and/or other sensors. In some embodiments, the self-zeroing process may be triggered by or initiated in response to the user selected an icon on a GUI associated with an application run by the local computing device. In some embodiments, the self-zeroing process may automatically be triggered by the window operator assembly (e.g., by the processor circuitry 106 of
In some embodiments, the self-zeroing operation may further include relaxing the closed position of the window, the open position of the window, the locked position of the lock, and/or the unlocked positon of the lock. For example, the window operator assembly may reduce the number of encoder counts for the window, the open position of the window, the locked position of the lock, and/or the unlocked positon of the lock from the fully open, fully closed, fully locked, and/or fully unlocked position encoder counts, such that the pressure on the components is relaxed in operation and the power operator of the motor is backed off from the full positions. The reduced number of encoder counts, which backs up the open, closed, locked, and/or unlocked positions from the full positions can include between 2/10ths of one percent and two percent.
More particularly, for the fully open position of the window and the locked and unlocked positions of the lock, the encoder counts may be reduced from the fully open, the fully locked, and the fully unlocked positions. For the fully closed position of the window, the window may be pushed to the fully closed position until the lock is in the locked position. Once the lock is engaged with the keepers, the motor may be backed-off to reduce stress, such as turning the motor backward from the fully closed position by 2/10ths of one percent and two percent.
In some embodiments, the computing device 440 may operate the application which is used to provide a process for setting up a window and/or for configuring wireless communication associated with the first wireless communication system by the window(s), such as Wi-Fi.
As previously described, the window operator assembly and/or window assembly may include one or more sensors. In some embodiments, the processor circuitry 442 may provide a notification of a sensor alert in response to communication from the window operator assembly caused by a sensor signal from a respective sensor (e.g., rain sensor triggered and window closed, Wi-Fi lost and window closed, errors, motion sensor or motor sensors manual movement, glass break sensors, CO sensor, temperature sensors).
In some embodiments, the computing device 440 may be used to update a wireless network setting for all windows of the building. For example, the processor circuitry 442 may instruct the user to scan a window ID on the window operator assembly in response to loss connection of a wireless communication and, in response to the scan, identify a plurality of window operator assemblies associated with the building ID and update each of the plurality of window operator assemblies to a new communication setting including the use of a new wireless communication system for wireless communications. The instruction may occur in response to the connection loss and/or notification by the user of a new wireless communication system. The configuration information for a home may be stored remotely, such as being stored by the cloud computing system, e.g., stored in the cloud (e.g., a cloud-based database). Therefore, scanning any window in that building (e.g., a house) can allow access to the information for all windows associated with that building.
As shown by
The window operator assembly 100 is connected to a window of a building, such as a window forming part of the window assembly 108 as illustrated by
In various embodiments, the communication circuitry 104 may provide a first type and a second type of wireless communications with a first wireless communication system and a second wireless communication system. In such embodiments, the processor circuitry 106 may identify connection loss between the communication circuitry 104 and the first wireless communication system, and in response, cause the communication circuitry 104 to switch to the second wireless communication system and to cause the window operator assembly 100 to perform an action, such as moving to a closed position and/or communicating the lost connection to the local computing device 554.
The local computing device 554 may identify a window ID associated with the window operator assembly 100, identify a building ID to associate with the window ID based on a user input, wirelessly communicate the window ID and the building ID to the remotely-located computing device 556, and wirelessly communicate with the processor circuitry 106 of the window operator assembly 100 to control a state of the window. As previously described, the local computing device 554 may include a display, and may provide a GUI and control the state of the window by communicating a message to the processor circuitry 106 indicative of at least one of a direction of movement of the window, a position of the window, and a speed of the movement of the window in response to user input(s) to the GUI.
The remotely-located computing device 556 may assign the window ID with the building ID in a database 558, and control changes to the assignment of the window ID to the building ID in the database 558 based on a set of rules. In some embodiments, the remotely-located computing device 556 includes a plurality of distributed computing devices used to provide a backend service, such as registering windows, buildings and associations between the same. The plurality of distributed computing devices may include servers and/or databases that form part of a cloud computing system. The remotely-located computing device 556 and/or portions thereof (e.g., the processor circuitry and memory circuitry) may form part of the plurality of distributed computing devices to provide the back-end service.
More particularly, the window system 565 illustrates an example system that further includes a hub device 555 which locally communicates using a local communication system or network with the plurality of window operator assemblies 100-1, 100-2, 100-3, 100-N and, optionally the local computing device 554. The hub device 555 may communicate over the network 552, such as to the cloud computing system and/or to the remotely-located computing device 556. In such embodiments, the plurality of window operator assemblies 100-1, 100-2, 100-3, 100-N, and optionally the local computing device 554 may not communicate with the cloud computing system and/or over the network 552. As a single hub device 555 is used to communicate with the cloud computing system, service costs with the cloud computing system may be reduced and/or the set-up of the system 565 may be simplified as compared to all devices communicating over the network 552. Further, similar to the building ID, the set-up of the system 565 may be tied to a device ID of the hub device 555, such as associating window IDs with the device ID of the hub device 555, and there may be similar restrictions on removing the association and/or allowing user control as previously described in connection to the building ID.
The hub device may include a physical layer networking device which is used to connect multiple device in the system 565 to the network 552. In some embodiments, the hub device 555 can communicate with the plurality of window operator assemblies 100-1, 100-2, 100-3, 100-N, and optionally the local computing device 554, using a local area network (LAN). The hub device 555 may include processor circuitry, memory circuitry, and communication circuitry, similar to that previously described by the local computing device. Although one hub device 555 is illustrated by
The plurality of wireless communication devices 100, 554, 556, 664, 666, 668, 670 include a window operator assembly 100 and the local computing device 554. The window operator assembly 100 is connected to a window and configured to adjust a state of the window, such as a position and/or locking or unlocking the window. The local computing device 554 can run an application to control the state of the window, e.g., via communication with the window operator assembly 100. In various embodiments, for security and/or other purposes, at least some of the control of the window may be local to the window operator assembly 100 and/or occur independent of communication with the local computing device 554. As some non-limiting examples, the window operator assembly 100 may automatically cause the window to close, without an instruction from the local computing device 554, in response to detection or other indication of rain and/or loss of wireless communication connection, among others.
The IOT system 660 may include other wireless communication devices located in or proximal to the building. Example wireless communication devices include an alarm system control device 666, an HVAC control device 668, a home automatic device 664, a wearable smart device 670, and other smart devices, such as weather devices, smart appliances (e.g., ovens, refrigerators, grills, faucets), and exercise machines.
In some embodiments, the IOT system 660 includes an alarm system control device 666. The alarm system control device 666 may control operations of an alarm system for the building. The alarm system control device 666 may communicate with the window operator assembly 100 and/or local computing device 554 to provide information associated with states of the windows and/or the alarm system for the building. For example, the communication may prevent activation of the alarm system when a window of the building is in an open position and/or is unlocked. In some embodiments, the alarm system control device 666 or the local computing device 554 may provide a notification to the user, via a display, noting the alarm system is not activated and/or is prevented from activating due to the state of the window and identifying the window. As a specific example, the alarm system control device 666 and local computing device 554 may be in communication with one another. In response to a user setting the alarm system to be on or activated, the alarm system control device 666 may send a message to the local computing device 554 to identify a state of the windows in the building. The local computing device 554 may identify that a window and/or a group of windows are in an open position, and communicate a message back to the alarm system control device 666 notifying the alarm system control device 666 of the open window(s). In response, the alarm system control device 666 may deny setting the alarm system to the on or activated state and may display a message on the display of the alarm system control device 666 notifying the user of the denial and/or identifying the window(s) in the open position. In some embodiments, the message may direct the user to access the local computing device 554 to close the window(s). Alternatively and/or in addition, the local computing device 554 may provide an alert to the user that notifies the user of the denial of setting the alarm system in the activated state due to the window(s) being open. The alert may prompt the user to close the window(s).
In some embodiments, the TOT system 660 includes an HVAC control device 668 and a plurality of window operator assemblies each connected to respective windows. The HVAC control device 668 may control operation of components of an HVAC system, such as a furnace, a heat exchanger, an air conditioner, a fan, and a thermostat, among other components. The HVAC control device 668 may communicate with the window operator assembly 100 and/or the local computing device 554 to provide information associated with states of the windows for the building. The communication may be used to create positive air pressure in the building for purposes of flushing air within the building. For example, the local computing device 554 may control or direct opening of a subset of the plurality of windows via communication with the plurality of window operator assemblies, closing of the remaining plurality of windows via the communication with the plurality of window operator assemblies, and activation of the HVAC system via communication with the HVAC control device 668 to create positive air pressure (e.g., shut-off cold air returns) and allow for outside (fresh) air to replace the old and potentially contaminated air being expelled. The positive air pressure may be used to push current (stale) air out of the building and pull new (fresh) air into the building. In other embodiments, the HVAC control device 668 may control the process by communicating with the local computing device 554 and activating the HVAC system in response to confirmation from the local computing device 554 of the subset of the plurality of windows being in the open position and the remaining being in the closed position.
In some embodiments, the positive air pressure may be used to evacuate contaminated air and/or to provide protection from contaminates in the air, such as for viruses. As a specific example, the positive air pressure may be used to provide fresh air in the building or a portion of the building to improve the air quality and reduce viral contaminates in the air. In some embodiments, the risk of exposure to a coronavirus, such as COVID-19, may be reduced by the positive air pressure. For example, a subset of windows in the building, associated with a location (e., room(s)) that users are to be located in, may be opened and the HVAC control device 668 creates positive air pressure in the location. As a specific example, a user may have visitors to their home and may select which room or rooms of their home that they will be located in and for an amount of time. A subset of the windows of the home associated with the selected room(s) may be opened and fresh air may be pulled in while current air is pushed out for the entire time that the visitors are present in the user's home. The selective activation in the selected room(s) of the home allows for targeted location of the positive air pressure that occurs automatically, rather than being applied in the entire home and without requiring the user to walk around the home and manually open windows.
In some embodiments, the IOT system 660 includes a home automation device 664. A home automation device 664 may receive human voice commands, translate the voice commands, and provide an operation in response to the translated voice commands, such as an Alexa, Siri, or Google Assistant-based device. The home automation device 664 may communicate with the window operator assembly 100 and/or the local computing device 554. For example, the home automation device 664 may receive a voice command from a user and, in response, direct the window operator assembly 100 to control a state of the window. The communication may be provided directly to the window operator assembly 100 or to the local computing device 554 which controls the window operator assembly 100. In some embodiments, the home automation device 664, the window operator assembly 100, and/or the local computing device 554 authorize the voice command and/or the control of the position of the window in response to a verification factor from a user approved device and/or a user approved device being within a threshold distance. In some embodiments, the verification includes a 2-step verification process. For example, the verification factor may be provided by local computing device 554 and/or a wearable smart device 670 after prompting the user to verify the authorization by the local computing device 554 and/or the wearable smart device 670.
As noted above, the TOT system 660 may include other devices, such as devices that provide weather information, information on the state of the building (e.g., an oven is on, which may impact a temperature), smart lights, sensors, irrigation controllers, drapery or blind controllers among other information that may be used by devices of the TOT system 660 to adjust operations. For example, using weather information, the local computing device 554 may automatically direct windows to be in different states and/or may suggest the windows be in the different states to the user. As an example, a weather application running on the local computing device 554 and/or the wearable smart device 670 may indicate that a thunderstorm is approaching and cause the windows in the building to close. As another example, a smart oven may notify the local computing device 554 of the oven being on and at a particular temperature, and along with information on the weather, notification of the setting of the HVAC system and/or settings by a user, the local computing device 554 may change the position of one or more windows, such as opening the windows in response to the HVAC being off, the temperature in the building going above a threshold temperature, and the temperature outside being near or below the threshold temperature.
