Abstract: The present disclosure provides an ambient light sensing system including an optical detector located beneath a display and a detector electronics. The detector electronics includes an integrator configured to integrate an output from the detector, at least one counter which is connected to the integrator, and a memory which is connected to the integrator. The at least one counter is synchronized to a synchronization signal of the display. The at least one counter causes values to be periodically written from the integrator into the memory.

Abstract: An optical device comprises an emitter for emitting light, a receiver for receiving reflected light and providing a data signal, a register for storing processing parameters comprising a baseline reference value, and a processing unit for processing the data signal using the processing parameters. The processing unit is configured to compare the data signal to the baseline reference value, and determine that a crosstalk calibration of the optical device is required based at least partially on the comparison.

Abstract: A proximity sensing device is disclosed comprising: a radiation emitter; a radiation sensor configured to sense a reflected radiation from the radiation emitter; a memory for storing a plurality of ambient radiation level ranges and a plurality of coefficients that map onto the plurality of ambient radiation level ranges; and processing circuitry configured to compensate an output from the radiation sensor for crosstalk by subtracting from the output a measured ambient radiation level scaled by either: a coefficient selected from the plurality of coefficients; or a value derived from the plurality of coefficients. A proximity sensing method and a proximity sensing calibration method are also disclosed.

Abstract: An I2C apparatus (100) comprising: a master device (102) and two slave devices connected through an I2C bus, whereby the two slave devices are programmed with the same default device address. A first slave device (108) is connected to the bus in a conventional configuration whereas a second slave device (110) is connected to the bus in a cross connected configuration such that a clock pin of the second slave is connected to the serial data line and the data pin of the second slave is connected to the serial clock line. In response to a detection that the data pin of the second slave is connected to the serial clock line, the second slave swaps the lines going from the clock and data pins to processing logic of the second slave; and modifies its default device address to ensure that each slave device has a unique device address.

Abstract: A method of proximity sensing which comprises emitting light from an emitter and detecting reflected light, applying an offset to the detected reflected light to provide an output signal indicative of proximity, determining an average signal of the output signal; determining whether drift has occurred by comparing the output signal to a first threshold and comparing the average signal to a different threshold, and adjusting the offset if drift is identified.

Abstract: The invention relates to a cell balancing module, particularly for voltage balancing of a stack of batteries. The cell balancing module comprises an interface (SPI, VrefH, VrefL) to input a coded reference voltage (Vref) and input nodes (In1, . . . , InN) for connecting a stack of energy storage cells (BAT1, . . . , BATn). A switching unit (SW) is connected to each of the input nodes (In1, . . . , InN) and a local balancing unit (loc) coupled to the switching unit (SW) and the interface (SPI, VrefH, VrefL). The local balancing unit (loc) is designed to compare the coded reference voltage (Vref) with cell voltages (VBAT1, . . . , VBATn) of the stack of energy storage cells (BAT1, . . . , BATn) to be connected and to charge balance the stack of energy storage cells (BAT1, . . . , BATn) to be connected depending on the comparison of coded reference voltage (Vref) and cell voltages (VBAT1, . . . , VBATn).
