User interface devices, including control panels to operate various systems and machineries (e.g., vehicles such as forklifts) and control their functionality, generally include user-actuatable implements (e.g., keyboard buttons) and other input/output devices that facilitate interaction with the environment of the particular system or machinery. Often, the system or machinery to be controlled are configured, or are used for, specific functionality, rendering at least some of the user-actuatable implements and other input/output device fitted on a standard-issue user interface device unneeded. The availability of more user-actuatable implements and other input/output devices on a standard-issue user interface device than are needed for operation of the particular system or machinery may result in unnecessary complexity to the operation of the system or machinery by users. This can result in longer training times for the user to learn how to use the system or machinery, and can also increase the likelihood of an accident occurring (e.g., due to decision-making delay in locating a particular button or implement on the user-interface, or pressing a wrong button).

Details of one or more implementations are set forth in the accompanying drawings and in the description below. Further features, aspects, and advantages will become apparent from the description, the drawings, and the claims.
These and other aspects will now be described in detail with reference to the following drawings.
Like reference symbols in the various drawings indicate like elements.
Disclosed herein are systems, devices, methods, and other implementations that include a control system (e.g., a computer-based control system, which, in some embodiments, may be a vehicle-mounted control system) comprising a receiving structure to receive a plurality of modular devices (e.g., mechanical tracks coupled to a tablet-like device into which modular devices, like modular keyboard buttons or modular sensors, can be fitted and secured via mechanical or electro-magnetic means). The control system further includes one or more of the plurality of modular devices coupled into respective locations on the receiving structure (i.e., the receiving structure can be fitted with as many of the modular devices as are needed, which may be fewer than the available space for fitting the plurality of modular devices), with each of the one or more of the plurality of modular devices (fitted onto the receiving structure) configured to transmit a respective short-range communication in response to receiving a respective stimulus by the each of the one or more of the plurality of modular devices. The control system further includes a communication module (e.g., a short-range transceiver, a wired communication interface, etc.) configured to communicate with the one or more of the plurality of modular devices coupled to the receiving structure, and a controller (e.g., processor-based controller) configured to perform a respective operation in response to receiving a short-range message from a respective one of one or more of the plurality of modular devices. In some embodiments, the controller configured to perform the respective operation may be configured to perform one or more modifiable operations in response to receiving the short-range message communication from the respective one of one or more of the plurality of modular devices (i.e., the particular operation caused as result of the receipt of the short-range message can be occasionally changed, and thus the control system can be configured to perform operations corresponding to the specific needs of the user configuring the control system). In some embodiments, at least one of the one or more of the plurality of the modular devices may include, for example, an actuatable keyboard button (e.g., a plastic or rubber-based button) configured to transmit a corresponding short-range communication in response to actuation of the actuatable keyboard button, a sensor configured to measure stimulus data (e.g., a gas sensor configured to detect one or more gases in an area in which the control system is located, an optical sensor, and so on), etc.
Thus, suppose, for example, that a control system to control operation of a forklift is to be realized. In such an example, a vehicle-mounted tablet with a receiving structure (e.g., tracks) is provided that can receive mechanically securable, or magnetically securable, buttons or other implements (a modular device may include mechanical projections/ribs placed on a housing of the modular device, that can be fitted into the tracks of the receiving structure). An appropriate size modular device may be selected from a repertoire of different size modular devices (e.g., with modular devices with larger surface areas being designated for more important configurable functions since they will be more prominently available on the configurable tablet). The selected modular device may be assigned, or may have been assigned, a unique identifier that will be transmitted to the communication module of the tablet device when the selected modular device is responding to some stimulus (e.g., detection of toxic gas, detection of mechanical actuation of the modular device, etc.) In situations where the selected modular device has a previously assigned identifier, that identifier may be retrieved through a barcode placed on the housing of the modular device, or by receiving a wireless communication (e.g., an RFID-based communication) from the modular device that includes the unique identifier assigned to it (the unique identifier may be stored in a non-volatile memory device within the housing of the modular device). During calibration/preparation of the tablet device (or whichever type of control device is being used), the tablet device may be configured to perform specific operations (e.g., generate control signals that can be provided to various electro-mechanical parts of the system or machinery controlled by the tablet device) in response to receiving a message that includes the unique identifier from the selected modular device. For example, the selected modular device may be designated to control upwards actuation of a mast of a forklift. Accordingly, the control system may execute an application or process that guides a user in matching or pairing the selected modular device to the operation of the particular system or machinery. The application or process may have been provided by the manufacturer of the system or machinery, and allows for the matching/pairing of unique identifiers (and other message content) to generation or suppression of control signaling controlling one or more of the sub-systems of the particular system/machinery).

The tablet-type controller 110 may be a vehicle-mounted tablet device that can be used to interface and control operation of a vehicle (such as a forklift 140 depicted in
In some embodiments, the controller may be a non-portable device, such as a user interface (touch-based, mechanical-button-based) that is directly attached to (integrated) to the structure of the machinery or system that the controller is to control (e.g., the controller's interface portion may be attached directly to a front/dashboard of the forklift 140 of
As shown in
As illustrated in
As noted, signal data generated by any of the modular devices may be transmitted through wireless communication using a wireless transmitter (which may be part of a wireless transceiver) included with the modular devices. For example, the signal data may be inductively transmitted from an inductive communication module (e.g., a coil-based antenna) and received by a corresponding receive antenna at the controller 110. In another example, at least one of the modular devices may be configured to transmit the signal data according to one or more short-range communication protocols such as RFID-based protocol (implemented in any appropriate frequency band, such as LF, UHF, etc.), a Bluetooth™ protocol, a Bluetooth-Low-Energy™ (BLE) protocol, near-filed protocols, etc.
In some embodiments, at least one of the various modular devices that are included with the controller 110 (e.g., via the receiving structure 120) may include modules/units that detect and respond to other types of stimulus or input. For example, modular devices such as the devices 130c-d (which are depicted as not including a depressible buttons) may be sensors configured to detect different properties relating to operation of the modular devices and/or the environment in which those modular devices are operating. For example, the sensors may include inertial/orientation sensors configured to measure data relating to motion and/or location of the sensors (and thus of the device to which they are attached). In another example, a sensor-type modular device may be configured to measure such data as the atmospheric content of the environment in which that modular device is placed. For instance, a modular sensor may be attached to the controller 110 to detect if certain toxic gases (carbon monoxide) are present, so as to issue appropriate alerts/alarms to the users of the control system (or of the machinery/system controlled by the controller 110). In another example, the sensor-type modular device may be a biometric sensor to receive biometric data from a user (e.g., the user operating the control system). Examples of biometric sensors may include a heart monitor, a blood-pressure monitor, blood-oxygen monitor, a thermistor, etc. The biometric sensor may be configured to monitor the medical conditions of the user/operator of the control system, and facilitate remedial action and delivery of aide to the user in the event that some medical emergency arises. Another example of a modular sensor device is an optical sensor configured to, for example, receive optical data from a direction substantially opposite a side of the control system comprising a display surface. The controller (e.g., the controller 110) may, for example, be configured to determine, based on optical data captured by the optical sensor, whether at least some of the optical data corresponds to features of an eye of the user using the control system. In other words, in this particular example, an optical sensor, implemented as one of the modular devices that can be fitted to the receiving structure of the control system, would collect data from which it can be determined if certain features of the user's face, such as the eye, are visible. This, in turn, would indicate whether the user is viewing a screen, or some other part of the controller. If it is determined that at least some of the optical data captured by the optical sensor corresponds to the features of the eye(s) of the user (e.g., based on image processing applied to the optical data to identify features in the image), the controller may then be configured to control activation state of a display (e.g., an LCD display, a bi-state display, etc.) Conversely, if, based on the optical data, it is determined that the user is not directly viewing the controller 110, the screen/display of the controller 110 may be de-activated (to thus conserve power). The optical data collected by an optical-sensor implemented as one of the sensor-type modular devices of the system 100 may also be used for other purposes (e.g., determine the level of ambient light, which in turn can be used to turn on or off lighting devices of the system or machinery controlled by the control system 100).
With reference now to
As shown, the example device 200 may include one or more transceivers (e.g., a LAN transceiver 206, a WLAN transceiver 204, a short-range transceiver 209, etc.) that may be connected to one or more antennas 202. The transceivers 204, and 206, and/or 209 may comprise suitable devices, hardware, and/or software for communicating with and/or detecting signals to/from a network or remote devices and/or directly with other wireless devices within a network. In some embodiments, by way of example only, the transceiver 206 may support wireless LAN communication (e.g., WLAN, such as WiFi-based communications) to cause the device 200 to be part of a WLAN implemented as an IEEE 802.11x network. In some embodiments, the transceiver 204 may support the device 200 to communicate with one or more cellular access points (also referred to as a base station) used in implementations of Wide Area Network Wireless Access Points (WAN-WAP), which may be used for wireless voice and/or data communication. A wireless wide area network (WWAN) may be part of a Code Division Multiple Access (CDMA) network, a Time Division Multiple Access (TDMA) network, a Frequency Division Multiple Access (FDMA) network, an Orthogonal Frequency Division Multiple Access (OFDMA) network, a Single-Carrier Frequency Division Multiple Access (SC-FDMA) network, a WiMax (IEEE 802.16), and so on. A CDMA network may implement one or more radio access technologies (RATs) such as cdma2000, Wideband-CDMA (W-CDMA), and so on. Cdma2000 includes IS-95, IS-2000, and/or IS-856 standards, and a TDMA network may implement Global System for Mobile Communications (GSM), Digital Advanced Mobile Phone System (D-AMPS), or some other RAT. In some embodiments, 4G networks, Long Term Evolution (“LTE”) networks, Advanced LTE networks, Ultra Mobile Broadband (UMB) networks, and all other types of cellular communications networks may also be implemented and used with the systems, methods, and other implementations described herein.
In some implementations, the device 200 may also include the short-range transceiver (interface) 209 configured to allow the device 200 to communicate according to one or more short-range communication protocols, such as, for example, Ultra Wide Band, ZigBee, wireless USB, Bluetooth™ (classical Bluetooth), Bluetooth-Low-Energy™ (BLE) protocol, etc. The transceiver 209 may be implemented using inductive coils to realize short-range inductive communication (which may also be used for inductive power transfer, with the generated inductive field being modulated to allow in-band communication). When the device on which a short-range interface 209 is included is configured to only receive short-range transmissions, the transceiver 209 may be a receiver and may be not capable of transmitting short-range communications.
As further illustrated in
As further illustrated in
Another type of a sensor/detector that may be included with a controller-based device, and that may be implemented as a modular sensor/detector (for subsequent fitting with a receiving structure of a controller) is a camera or some other type of optical sensors (e.g., a charge-couple device (CCD)-type camera, a CMOS-based image sensor, etc.) Such an optical sensor may be configured to produce still or moving images that may be displayed on a user interface device, and that may be further used to determine an ambient level of illumination and/or information related to colors and existence and levels of UV and/or infra-red illumination, and/or other types of sensors. The optical sensor may be positioned (whether the sensor has been a previously built-in sensor, or has been fitted to the receiving structure forming part of another device's housing) so that its aperture and/or sensor array are directed in a direction opposite that of a display surface of a controller so that the optical sensor (or camera) would receive image/optical data corresponding to the scene viewed from the front of the controller. Thus, in some embodiments, when a user is facing the optical sensor, an image-processing procedure may be applied to images captured by the optical sensor to determine if features of the user (e.g., eyes of the user) are detectable, and, if detectable, to determine if the user is looking at the display or screen of the controller. Such a determination can then be used to control activation of the screen (and thus conserve power) so that the screen or display are activated only when it is determined that the user of a controller (in communication with the optical sensor, which may be a modular sensor or a built-in sensor) is looking at the screen or display.
Additional types of sensors that may be used with the example device 200, or that may be included with a controller implemented based on the example device 200 (e.g., modular devices received by a receiving structure forming part of the housing of such a controller) may include gas detectors/sensors configured to detect the presence of certain substances in the area in which the sensor is located, and/or biometric sensors to measure biometric data relating to a user of the example device 200. Example sensors that may be used (and which may subsequently be fitted into receiving a structure configured to receive modular sensors) include carbon-monoxide sensors, smoke detectors, radioactive detectors, etc. The inclusion of such modular gas sensors (and/or other safety-related devices) can configure the device 200 as an intrinsically-safe device that will inhibit operation of the device 200, and may also inhibit operation of any machine or equipment controlled by the device 200, in response to detection or determination that the device 200 is located in a hazardous, or unsafe, environment.
As noted, any one of the sensors 212 may be implemented as a modular device that includes a housing structured to be fitted or attached to a receiving structure of some master device (e.g., a frame extending from, or forming part of, a housing of a controller that uses the modular sensors). When a sensor is implemented as a modular device, the sensor may include a power source such as a battery, a power conversion unit to receive electrical power through a physical connection (physical interface to physically connect a power port to the controller, and to draw power therefrom), and/or a wireless power receiver that can generate an electric voltage or current from a wireless power field (created by the controller) or from ambient radio-frequency signals received by the wireless power receiver. A modular sensor would generally also include a communication module, which may comprise a physical communication interface for wired communication with the controller, or a wireless communication module to transmit wireless signals to the controller. Communications sent by a modular sensor may include identification information (to identify the sensor sending the data) and the actual data measured by the modular sensor.
In some embodiments, data collected by the various sensors 212 (be it motion data, location data, environmental data, etc.) may be processed by a controller and used to perform control operations. For example, detection of a toxic gas by a gas-sensor (modular, or built-in a controller such as the tablet-based device 110 or the smartphone-based device 150 of
With continued reference to
The processor 210 may be connected to the transceivers 204 and/or 206, the SPS receiver 208 and the sensors 212. The processor may include one or more microprocessors, microcontrollers, and/or digital signal processors that provide processing functions, as well as other calculation and control functionality. The processor 210 may also include memory 214 for storing data and software instructions for executing programmed functionality within the device. The memory 214 may be on-board the processor 210 (e.g., within the same IC package), or may be external memory to the processor and functionally coupled over a data bus. Further details regarding an example embodiments of a processor or computation system, which may be similar to that of the processor 210, are provided below in relation to
The functionality implemented via software may depend on the particular device at which the memory 214 is housed, and the particular configuration of the device and/or the devices with which it is to communicate. For example, if the device 200 is used to implement a controller/control device (such as the tablet-based controller 110 that may be used to control operation of a system or machinery such as the forklift 140), the device may be configured (via software modules/applications provided on the memory 214) to implement a process to receive signals from one or more modular devices (that may be fitted on a receiving structure or frame coupled to a housing of the controller), identify and/or authenticate the control signals (to determine which modular device sent to the signals), determine and process data included with the received signals (e.g., duration of signals, content of signals, etc.), and cause performance of an operation corresponding to the received signals (e.g., generate control signals to control the system or machinery controlled by the controller). In some implementation, the controller may also be configured to calibrate/set-up/or configure the controller to perform a number of operations responsive to different signals received from different modular devices. Thus, an application running on the controller may be used to pair a particular operation (e.g., generation of a control signal to cause a mechanical output of the system being controlled) to a signal(s) received from a particular modular device. For instance, the application may pair/match a control signal to actuate a mast of a forklift to a signal received from some specific modular device (the modular device may be custom-selected by a user of the controller, according to the particular needs and conveniences of that user). In embodiments in which the device 200 is used to implement a modular device (such as an actuatable user-input device, or a sensor device), the instructions stored on the memory 214 may include instructions to, for example, collect environmental data (if the modular device is a sensor) or record the occurrence of an event (e.g., a key being depressed), and communicate (through a wired or wireless interface) signals representative of the data collected or recorded.
The example device 200 may further include a user interface 250 which provides any suitable interface systems, such as a microphone/speaker 252, a keypad 254, and a display 256, that allow user interaction with the device 200. The user interface 250, be it an audiovisual interface (e.g., a display and speakers), or some other type of interface (visual-only, audio-only, tactile, etc.), is configured to provide status data, alert data, and so on, to a user using the particular device 200. The microphone/speaker 252 provides for voice communication functionality, and the display 256 includes any suitable display, such as, for example, a backlit LCD display, and may further include a touch screen display for additional user input modes. In some embodiments, the display 256 may be a bi-state display configured to maintain (i.e., without requiring on-going supply of energy) the display of particular data (e.g., characters and/or graphics) until the state (i.e., the data) for the bi-state display is changed/updated again. Further details regarding use of a bi-state display for some implementations of the device 200 are provided, for example, in U.S. Pat. No. 8,616,457, entitled “RFID display label for battery packs,” the content of which is incorporated herein by reference in its entirety. The microphone/speaker 252 may also include or be coupled to a speech synthesizer (e.g., a text-to-speech module) that can convert text data to audio speech so that the user can receive audio notifications. Such a speech synthesizer may be a separate module, or may be integrally coupled to the microphone/speaker 252 or to the processor 210 of the device of
The keypad 254 of the device 254 may include suitable buttons for user input, and may, as noted, include modular devices implementing, for example, modular depressible keys selected for inclusion with a controller (implemented according to the example device 200 of
With reference now to
In some embodiments, coupling the one or more modular device to the receiving structure may include slidably fitting at least one of the one or more modular devices into tracks defined in the receiving structure of the control system, and/or magnetically mounting the at least one of the one or more modular devices to the receiving structure of the control system. Other attachment mechanisms to attach some of the modular devices may also be used. As noted, the receiving structure may include a frame with tracks into which at least part of the housing of the modular devices to be included are fitted. The frame/receiving structure may include grooves and/or latches to securely attach the modular devices to the frame/receiving structure, but the coupling may simply be achieved through tension forces resulting from a snug fit between the portions of the modular devices' housings, and the receiving structure. In some embodiments, one modular device may be a modular optical sensor that may be used to determine, among other things, whether a user using the controller (to control the system or machinery) is looking at the user-interface (e.g., at the screen), and based on that determination, to activate or de-activate the screen/display (thus preserving power). Accordingly, in such embodiments, coupling to the receiving structure the at least one modular sensor may include coupling to the receiving structure at least one optical sensor to receive optical data from a direction opposite a side of the control system comprising a display surface of the control system. In such embodiments, the method may further include determining, based on optical data received from the optical sensor, whether at least some of the optical data corresponds to features of an eye of a user facing the side of the control system comprising the display surface.
