Abstract: A multifunctional infrared (IR) module is configured for multiple IR applications without an additional microcontroller to be integrated into a computing device and is able to utilize voltage control instead of current control. The multifunctional IR module includes an IR light emitting diode (LED), and an IR receiver (e.g., photodiode or phototransistor). In one embodiment, the multifunctional IR module includes a resistor that is connected to the cathode of the IR LED and the drain of a transistor, with the source of the transistor grounded. In some embodiments, the multifunctional IR module additionally includes a red LED. Various configurations of the multifunctional IR module are able to perform one or more of the following functions: IR in (receiving IR signals), IR out (generating IR signals), heart rate sensing, SpO2 (oxygen saturation) sensing, distance/proximity detection, gesture detection, LED control, and ambient light detection.

Abstract: A system, a method and a computer-readable medium are disclosed for generating an infrared code from an envelope waveform of an infrared signal on a computing device. An envelope waveform is created by reflections of the original infrared signal between the emitter of the infrared signal and the receiver of the computing device. The computing device generates an intermediate signal from the received IR signal and then determines a digital envelope waveform from the intermediate signal. The computing device queries a database storing known pairs of digital envelope waveforms and IR codes and receives an IR code.

Abstract: A codeset identifier for an infrared codeset that is compatible with an electronic device can be determined without requiring the user to manually input information about the electronic device. The user points an infrared device that is configured to control the electronic device at a computing device and presses a button, which causes the infrared device to emit an infrared signal that encodes a command representing the button that was pressed. Because the infrared device is configured to control the electronic device, an infrared code associated with the emitted infrared signal is part of the codeset that controls the electronic device and can be used to identify other infrared codes that are also compatible with the electronic device. The computing device extracts the infrared code from the received infrared signal and sends a query based on the infrared code to a server, which accesses an association table to find the codeset identifier corresponding to the infrared code.

Abstract: Disclosed is an integrated LED package for a client device. The integrated LED package includes a flash LED chip, an IR LED chip, and an optional reflective element. The IR LED chip includes an IR LED that emits a cone of IR light, for example, to send commands to another client device such as a TV, to control the TV. The reflective element modifies the cone of IR light such that a TV positioned in front of the client device is likely to receive IR light emitted from the client device. The integrated LED package includes a common anode for both the flash LED and the IR LED. Thus, the integrated LED package may reduce its overall size in comparison to a LED package that does not include a common anode, e.g., the LED package includes a separate anode each for the flash LED and the IR LED.

Abstract: A system and a method are disclosed for compensating for discontinuous clock signals, default-high data buses, when generating and receiving an infrared signal on a mobile device with minimal hardware. The system can compensate for clock signals that are discontinuous using an effective bitrate in place of a nominal bitrate when processing signals. The effective bitrate can be determined by determining the length of a break in the clock signal that is discontinuous and adjusting the nominal bitrate based on the length and recurrence frequency of the break in the clock signal. Additionally, processed signals transferred on default-high data buses can be inverted to ensure the correct IR signal is output or received.

Abstract: A system and a method are disclosed for generating an infrared signal on a mobile device. The infrared signal is generated on a mobile device by generating a bitstream based on information to be transmitted as an infrared signal. The bitstream is modulated and output on a bus to an infrared-emitting diode. The bitstream is processed in a software layer configured on the computing device, enabling the computing device to generate and process signals without additional hardware configured on the device.

The mobile device receives an infrared signal by creating an intermediate bitstream based on the received infrared signal. The intermediate bitstream is trimmed, downsampled, and demodulated in the time domain. The intermediate bitstream is then converted into a raw infrared code. The received bitstream is processed in a software layer, enabling the mobile device to process infrared signals without the use of additional hardware configured on the mobile device.
