BACKGROUND
Advances in technology and engineering have allowed designers and manufacturers to offer more sophisticated electronic devices to consumers. The development of the remote control has allowed these electronic devices to be wirelessly controlled by the consumers. The remote control has evolved from controlling simple operations, such as adjustment of the volume of these electronic devices and/or the programming being output by these electronic devices to provide some examples, to include more complex operations, such as textual searching and/or audible voice commands to provide some examples. The remote control has progressed from having programming channel and/or volume selectors to control these simple operations to include an alphabetical, a numeric, or an alphamerical keypad for entering alphanumeric characters, and/or one or more data pads to control these more complex operations. Moreover, the remote control has further evolved with the introduction of the Internet of Things (IoT). The Internet of Things (IoT) represents an ever-growing inter-network of physical devices, vehicles, buildings, and/or other items that are embedded with electronics, software, sensors, actuators, and network connectivity which enable these devices, vehicles, buildings, and/or other items to exchange data. The remote control has advance to even allow these devices, vehicles, buildings, and/or other items to be wirelessly controlled by the consumers.

Exemplary Remote Control Device Testing Environment
FIG. 2 illustrates a block diagram of an exemplary remote control device testing environment according to an embodiment of the present disclosure. As to be described in further detail below, a remote control device testing environment 200 evaluates operational performance of physical implementations of remote control devices as opposed to software simulations of their operational performance. This operational performance of the physical implementations of the remote control devices allows the integrated circuits of the remote control devices as well as integrated circuit interfaces electrically coupling these integrated circuits to each other to be evaluated. Additionally, the interconnection, such as electrical coupling to provide an example, between these integrated circuits and/or the integrated circuit interfaces can be evaluated which otherwise would not be evaluated by software simulation alone. Moreover, the evaluating of this operational performance of the physical implementations of the remote control devices allows these remote control devices to be in evaluated in a real world environment with exposure to various environmental factors, such as temperature, humidity, and/or electromagnetic interference to provide some examples. Furthermore, the evaluating of this operational performance of the physical implementations of the remote control devices allows interactions between these remote control devices and other electronic devices, such as the one or more media electronic devices 102 and/or the one or more non-media electronic devices 104 as described above in FIG. 1, to be evaluated. As illustrated in FIG. 2, the remote control device testing environment 200 includes automatic test equipment (ATE), also referred to as automated test equipment, 202 and a remote control under test (RCUT) 204 which are mechanically and electrically connected to each other using an evaluation interface 206. The remote control device 200 can represent an exemplary embodiment of one or more of the remote control devices 122 as described above in FIG. 1.
In the exemplary embodiment illustrated in FIG. 2, the ATE 202 evaluates operational performance of hardware and/or software of the RCUT 204. As to be described in further detail below, the ATE 202 executes a testing script to control the overall configuration and/or operation of the RCUT 204 to cause the RCUT 204 to perform one or more operations. In an exemplary embodiment, the testing script, when executed by the ATE 202, causes the RCUT 204 to electrically, as opposed to mechanically, activate one or more mechanical push button switches of the RCUT 204 to cause the RCUT 204 to perform the one or more operations. In this exemplary embodiment, this electrical activation of the one or more mechanical push button switches simulates physical activation, for example, pushing, of the one or more mechanical push button switches by a user of the RCUT 204. Thereafter, the ATE 202, when executing the testing script, can measure the operational performance of the hardware and/or the software of the RCUT 204 in performing the one or more operations. As illustrated in FIG. 2, the ATE 202 includes a memory device 208, a processor 210, and a physical layer interface (PHY) 212.
In the exemplary embodiment illustrated in FIG. 2, the memory device 208 stores the testing script to control the overall configuration and/or operation of the RCUT 204. The memory device 208 can be implemented as a volatile memory storage device, such as a random-access memory (RAM) storage device to provide an example, which requires power to maintain the electronic data, or a non-volatile memory storage device, such as a read-only memory (ROM) storage device to provide an example, which can maintain the electronic data even when not powered. The RAM storage device can be implemented in a dynamic random-access memory (DRAM), a static random-access memory (SRAM), and/or a non-volatile random-access memory (NVRAM), often referred to as a flash memory, configuration to provide some examples. The ROM storage device can be implemented in programmable read-only memory (PROM), a one-time programmable ROM (OTP), an erasable programmable read-only memory (EPROM) and/or an electrically erasable programmable read-only memory (EEPROM) configuration to provide some examples.
The testing script represents a sequence of instructions and/or one or more parameters to be used by the sequence of instructions to evaluate the operational performance of the hardware and/or the software of the RCUT 204. For example, the one or more parameters can indicate one or more mechanical push button switches from among the multiple mechanical push button switches of the RCUT 204 are to be activated. In this example, the sequence of instructions can cause the processor 210, which is to be described in further detail below, to activate the one or more mechanical push button switches in accordance with the one or more parameters to cause the RCUT 204 to perform the one or more operations. In an exemplary embodiment, the multiple mechanical push button switches of the RCUT 204 can include one or more mechanical push button switches associated with one or more electronic devices, such as one or more of the one or more media electronic devices 102 and/or the one or more non-media electronic devices 104 as described in FIG. 1 to provide some examples. In this exemplary embodiment, the sequence of instructions can cause the processor 210, which is to be described in further detail below, to activate the one or more mechanical push button switches associated with the one or more electronic devices to allow the processor 210 to evaluate a handshaking procedure, referred to as pairing, between the RCUT 204 and the one or more electronic devices.
Furthermore, the memory device 208 can store a software application to be executed by the RCUT 204. In an exemplary embodiment, the software application is specifically designed to perform a group of coordinated functions, tasks, operations and/or procedures. In some situations, this software application can be stored in a high-level programming language, such as the JavaScript and the C programming language to provide some examples. In these situations, the memory device 208 can further store a complier, which when executed by the processor 210, allows the software application stored in the high-level programming language to be translated to a low-level programming language, such as machine code or assembly language to provide some examples, for execution by the RCUT 204. This allows the software application to be executed by the RCUT 204 to be changed, for example, optimized, on-the-fly while the ATE 202 evaluates the operational performance of the RCUT 204.
The processor 210 executes the testing script stored in the memory device 208 to cause the RCUT 204 to evaluate the operational performance of the hardware and/or the software of the RCUT 204. In the exemplary embodiment illustrated in FIG. 2, the processor 210 executes the sequence of instructions specified by the testing script and/or the sequence of instructions in accordance with the parameters specified by the testing script to cause the hardware and/or the software of the RCUT 204 to perform the one or more operations. The processor 210, when executing the testing script, selectively electrically activates one or more mechanical push button switches from among the multiple mechanical push button switches of the RCUT 204 to cause the RCUT 204 to perform the one or more operations. In an exemplary embodiment, the processor 210 sends one or more electrical signals, such as one or more electrical pulses to provide an example, to the one or more mechanical push button switches to activate these mechanical push button switches. The one or more electrical signals simulate physical activation, for example, pushing, of the one or more mechanical push button switches by a user of the RCUT 204.
The processor 210, while executing the testing script, can measure one or more characteristics, parameters, and/or attributes associated with the operational performance of the hardware and/or the software of the RCUT 204 in performing the one or more operations. In some situations, as described above, the testing script, when executed by the processor 210, can evaluate interactions between the RCUT 204 and other electronic devices, such as the one or more media electronic devices 102 and/or the one or more non-media electronic devices 104 as described above in FIG. 1. In these situations, the processor 210 can measure a length of time, referred to as button press speed, necessary for the one or more mechanical push button switches to be activated before one or more commands associated with the one or more mechanical push button switches are received by these other electronic devices. Moreover, the processor 210, while executing the testing script, can evaluate the operational performance of the hardware and/or the software of the RCUT 204 under extensive usage or loading to ensure the software application of the RCUT 204 continues to function properly, namely, does not exit, hang, or freeze to provide some examples. In an exemplary embodiment, the processor 210, while executing the testing script, can electrically activate the one or more mechanical push button switches more times per second when compared to conventional testing of physically activating the one or more mechanical push button switches by physically depressing the one or more mechanical push button switches. For example, the processor 210, while executing the testing script, can electrically activate the one or more mechanical push button switches hundreds or even thousands of times per second as compared to tens of times per second if the one or more mechanical push button switches were physically activated by physically depressing the one or more mechanical push button switches. Furthermore, the RCUT 204 can include one or more electric batteries as described above in FIG. 1. And as described above in FIG. 1, the RCUT 204 dissipates electrochemical energy stored in the one or more electric batteries as the one or more remote control devices 122 control operations of the other electronic devices. The processor 210, while executing the testing script, can measure a duration in time, referred to as battery-life, before the one or more electric batteries need replacing and/or recharging.
Thereafter, the processor 210 can compare the one or more characteristics, parameters, and/or attributes associated with the operational performance of the hardware and/or the software of the RCUT 204 with an electrical design specification to ensure the one or more characteristics, parameters, and/or attributes associated with the operational performance of the hardware and/or the software of the RCUT 204 satisfies operational performance for these operations as outlined in the electrical design specification. For example, the processor 210 can compare the measured button press speed as described above with a button press speed as outlined in the electrical design specification to ensure the measured button press speed satisfies the button press speed as outlined in the electrical design specification. As another example, the processor 210 can compare the measured battery-life with a battery-life as outlined in the electrical design specification to ensure the measured battery-life, satisfies the battery-life as outlined in the electrical design specification. Moreover, the processor 210, when executing the testing script, can provide an indication of whether the RCUT 204 operates as expected, namely, the performance of the one or more operations satisfies the operational performance for these operations as outlined in the electrical design specification. Alternatively, or in addition to, in these situations, the processor 210, when executing the testing script, can provide an indication of whether the RCUT 204 operates unexpectedly, namely, the performance of the one or more operations does not satisfy the operational performance for these operations as outlined in the electrical design specification.
The PHY 212 provides a wireless interface between the ATE 202 and the RCUT 204 for wirelessly communicating information between the ATE 202 and the RCUT 204. In an exemplary embodiment, this wireless interface is implemented in accordance with one or more wireless networking communication standards or protocols, such as a version of an Institute of Electrical and Electronics Engineers (I.E.E.E.) 802.11 communication standard, for example, 802.11a, 802.11b/g/n, 802.11h, and/or 802.11ac which are collectively referred to as Wi-Fi, an I.E.E.E. 802.16 communication standard, also referred to as WiMax, a version of a Bluetooth communication standard, a version of a ZigBee communication standard, a version of a Z-Wave communication standard, a version of a IPv6 over Low power Wireless Personal Area Networks (6LoWPAN) communication standard, a version of Insteon, an ISO/IEC 14543-3-10 communication standard, also referred to as EnOcean, and/or or any other wireless communication standard or protocol that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the present disclosure. For example, the PHY 212 can communicate the software application to be executed by the RCUT 204 stored within the memory device 208 to the RCUT 204 for installation within the RCUT 204.
In the exemplary embodiment illustrated in FIG. 2, the one or more mechanical push button switches of the RCUT 204 are mechanically and electrically connected to the ATE 202. This electrical activation of the one or more mechanical push button switches simulates physical activation, for example, pushing, of the one or more mechanical push button switches by the user of the RCUT 204. The one or more mechanical push button switches, in response to being electrically activated by the ATE 202 executing the testing script, perform the one or more operations to be evaluated by the ATE 202 as described above. As illustrated in FIG. 2, the RCUT 204 includes a user interface 210, a processor 212, a memory device 214, and a physical layer interface (PHY) 216.
The user interface 210 includes the one or more mechanical push button switches which are selectively chosen from multiple mechanical push button switches. In the exemplary embodiment illustrated in FIG. 2, the multiple mechanical push button switches can be associated with one or more simple operations, such as adjustment of the volume of the other electronic devices and/or the programming being output by the other electronic devices to provide some examples. However, the multiple mechanical push button switches can be associated with one or more other complex operations, such as textual searching to provide an example, which will be recognized by those skilled in the relevant art(s) without departing from the spirit and scope of the present disclosure. The one or more mechanical push button switches can include one or more power buttons, one or more device selection buttons to remotely select one or more electronic devices, such as one or more of the one or more media electronic devices 102 and/or the one or more non-media electronic devices 104 as described above in FIG. 1 for control, one or more programming channel and/or volume selectors, an alphabetical, a numeric, or an alphamerical keypad for entering alphanumeric characters, and/or one or more data pads for navigating menus on the one or more electronic devices.
In an exemplary embodiment, the multiple mechanical push button switches include first switching contacts, second switching contacts, third switching contacts, and actuators. In this exemplary embodiment, the multiple mechanical push button switches can be physically activated by pushing on the actuators. This pushing of the actuators displaces the third switching contacts in such a manner to be in mechanical contact with the first switching contacts and the second switching contacts to electrically connect the first switching contacts and the second switching contacts to each other. In this situation, the multiple mechanical push button switches can be characterized as being physically activated to allow one or more electrical signals to pass between the first switching contacts and the second switching contacts onto the processor 212 for further analysis. In the exemplary embodiment illustrated in FIG. 2, the ATE 202 is mechanically and electrically connected to the first switching contacts and/or the second switching contacts. The ATE 202 can electrically activate a corresponding mechanical push button switch of the multiple mechanical push button switches by sending the one or more electrical signals, as described above, to the first switching contact and/or the second switching contact of the corresponding mechanical push button switch to simulate the physical pushing of the actuator of the corresponding mechanical push button switch.
The processor 212 controls the overall configuration and operation of the RCUT 204. In the exemplary embodiment illustrated in FIG. 2, the processor 212 can execute a software application stored in the memory device 214 to configure the configuration and operation of the RCUT 204. In some situations, this software application can be provided by the ATE 202 and stored in the memory device 214. In an exemplary embodiment, the software application can be associated with a mapping of the multiple mechanical push button switches to one or more operations to be performed by the RCUT 204. In this exemplary embodiment, the processor 212, when executing the software application, can receive one or more electrical signals from the ATE 202 via the first switching contact and/or the second switching contact of a corresponding mechanical push button switch from among the mechanical push button switches. In this exemplary embodiment, the processor 212 can determine one or more corresponding operations, such as one or more commands to provide an example, associated with the corresponding mechanical push button switch from the mapping of the multiple mechanical push button switches. Thereafter, the processor 212 can cause the RCUT 204 to perform the one or more corresponding operations associated with the corresponding mechanical push button switch. For example, the processor 212, when executing the software application, can receive one or more electrical signals from the ATE 202 via the first switching contact and/or the second switching contact of a <volume up>mechanical push button switch or a <volume down>mechanical push button switch. In this exemplary embodiment, the processor 212 can determine a <volume up>command or a <volume down>command from the mapping of the multiple mechanical push button switches. Thereafter, the processor 212 can cause the RCUT 204 to provide the <volume up>command or the <volume down>command provide to a display device, such as one of the one or more display devices 106 as described above in FIG. 1, to increase or decrease an audio output volume of the display device.
The memory device 214 can store the software application to be executed by the RCUT 204. In an exemplary embodiment, the software application represents a software application which is specifically designed to perform a group of coordinated functions, tasks, operations and/or procedures. In some situations, this software application can be stored in a high-level programming language, such as the JavaScript and the C programming language to provide some examples, and/or a low-level programming language, such as machine code or assembly language to provide some examples, for execution by the RCUT 204.
The PHY 216 provides a wireless interface between the ATE 202 and the RCUT 204 for wirelessly communicating information between the ATE 202 and the RCUT 204. In an exemplary embodiment, this wireless interface is implemented in accordance with one or more wireless networking communication standards or protocols, such as a version of an Institute of Electrical and Electronics Engineers (I.E.E.E.) 802.11 communication standard, for example, 802.11a, 802.11b/g/n, 802.11h, and/or 802.11ac which are collectively referred to as Wi-Fi, an I.E.E.E. 802.16 communication standard, also referred to as WiMax, a version of a Bluetooth communication standard, a version of a ZigBee communication standard, a version of a Z-Wave communication standard, a version of a IPv6 over Low power Wireless Personal Area Networks (6LoWPAN) communication standard, a version of Insteon, an ISO/IEC 14543-3-10 communication standard, also referred to as EnOcean, and/or or any other wireless communication standard or protocol that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the present disclosure. For example, the PHY 216 can communicate one or more commands to other electronic devices, such as the one or more media electronic devices 102 and/or the one or more non-media electronic devices 104 as described above in FIG. 1, to cause the other electronic devices to perform the one or more corresponding operations associated with the electrically activated mechanical push button switches.
The evaluation interface 206 represents a hardwired interface between the ATE 202 and the RCUT 204. As illustrated in FIG. 2, the evaluation interface 206 includes wired communication links 218.1 through 218.n.

In the exemplary embodiment illustrated in FIG. 2, the wired communication links 218.1 through 218.n are mechanically and electrically connected to the multiple mechanical push button switches of the user interface 210 as described above. For example, the wired communication links 218.1 through 218.n can be directly soldered to the first switching contacts and/or the second switching contacts of the multiple mechanical push button switches as described above allowing one or more electrical signals to pass from the ATE 202 to the first switching contacts and/or the second switching contacts of the multiple mechanical push button switches and onto the processor 212 for further processing. Those skilled in the art(s) will recognize other mechanisms, such as silver conductive epoxy to provide an example, are possible for mechanically and electrically coupling the wired communication links 218.1 through 218.n to the first switching contacts and/or the second switching contacts of the multiple mechanical push button switches of the user interface 210.
