    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 stroboscope with an integral optical reflective sensor, which can be removable or fixed, contains a light emitting source, a light sensitive receiver, a pulse conditioning circuit, a stroboscope circuit, a blanking circuit, and a stroboscope light source. The light emitting source projects a light beam to a reflective target. The reflected light beam from the reflective target is detected by the light sensitive receiver. The pulse conditioning circuit generates a set of electrical pulses coincident with the reflected light beam which are sent to the stroboscope circuit. Depending on the signal received by the stroboscope circuit, the stroboscope light source is triggered. The blanking circuit prevents false triggering of the stroboscope light source by introducing a time delay. The time delay is applied when the stroboscope light source is switched on and for a finite time after the stroboscope light source is switch off.

    Abstract: A method for transmitting a signal using an optical coupling device includes converting a first electric signal into an optical signal, converting the optical signal into a first current, and outputting a second current that corresponds to the first current as a second electric signal. The second current may be larger than the first current.

    Abstract: A light sensitive circuit includes a light sensing capacitor and a driving transistor. The light sensing capacitor is configured to sense light of a predetermined one or more wavelengths. The driving transistor includes a gate electrode electrically connected to the light sensing capacitor and is configured to generate a light sensing current according to a voltage of the gate electrode in the driving transistor. A light sensing accuracy and a light sensing signal to noise ratio (SNR) of the display apparatus including a plurality of such light sensing capacitors may be improved relative to ones that do not include such light sensing capacitors.
