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: Techniques are provided for estimating the direction of a laser source under non-uniform illumination conditions such as laser speckle. An example system may include a detector array comprising sensors configured to detect the amplitude of the received laser signal. The sensors are disposed on the array at unique orientation angles relative to each other. The sensor size is selected based on the speckle pattern of the laser signal such that the sensors are small enough to be uniformly illuminated by the laser signal in the presence of speckle. The system also includes an amplitude ratio calculation circuit configured to calculate ratios of the amplitudes between each of two sensors of one or more pairs of sensors. The system further includes an angle of arrival calculation circuit configured to estimate the direction of the source of the laser signal based on the calculated ratios and the orientation angles of the sensors.

Abstract: Various embodiments include systems and methods to provide selectable variable gain to signals in measurements using incident radiation. The selectable variable gain may be used to normalize signals modulated in measurements using incident radiation. The selectable variable gain may be attained using a number of different techniques or various combinations of these techniques. These techniques may include modulating a modulator having modulating elements in which at least one modulating element acts on incident radiation differently from another modulating element of the modulator, modulating the use of electronic components in electronic circuitry of a detector, modulating a source of radiation or combinations thereof. Additional apparatus, systems, and methods are disclosed.

Abstract: A calibration system is provided including an aperture layer, a lens layer, an optical filter, a pixel layer and a regulator. The aperture layer defines a calibration aperture. The lens layer includes a calibration lens substantially axially aligned with the calibration aperture. The optical filter is adjacent the lens layer opposite the aperture layer. The pixel layer is adjacent the optical filter opposite the lens layer and includes a calibration pixel substantially axially aligned with the calibration lens. The calibration pixel detects light power of an illumination source that outputs a band of wavelengths of light as a function of a parameter. The regulator modifies the parameter of the illumination source based on a light power detected by the calibration pixel.
