  • Patent number: 10362994
    Abstract: A bio-sensing device (and method) calibrates a time period used to make bio-physical measurements. The device initiates a light source sense phase followed by a first ambient sense phase and a second ambient sense phase. In the light source sense phase, the device is configured to receive a digital value indicative of current through a photodetector while the light source circuit is enabled and in each of the first and second ambient sense phases, the device is configured to receive digital values while the light source circuit is disabled. The device iteratively varies the time period between the phases until the digital value received during the first ambient sense phase is within a threshold of the digital value received during the second ambient sense phase. It then applies the same time separation between the light source sense phase and the ambient phase thereby equalizing the magnitude of the ambient light in the two phases.

  • Patent number: 10365761
    Abstract: A capacitive sensing methodology is suitable for sensing touch position along a sensor track based on touch capacitance based on touch position and touch pressure. The method is operable with a capacitive sensor including first and second capacitive sensor electrodes juxtaposed in a complementary configuration to define the sensor track, the complementary first and second sensor electrodes configured such that, as touch position moves along the sensor track, the electrode capacitance CSA of one sensor electrode monotonically decreases, and the electrode capacitance CSB of the complementary other sensor electrode monotonically increases, so that the touch capacitance corresponds to a combination of CSA and CSB. Pressure-compensated touch position data is generated from touch position information generated based on position and pressure functions, where the position function generates position information based on CSA and CSB, and the pressure function generates pressure information based on CSA and CSB.

  • Patent number: 10359321
    Abstract: An integrated circuit and method are provided for accurately measuring the temperature of a die of the integrated circuit. Pairs of diodes are driven with different currents in order to generate a series of thermal voltages. The ADC measures the series of thermal voltages against an external reference voltage. Based on these thermal voltage measurements, the ADC calculates the die temperature. The different currents used to generate the series of thermal voltages are selected at specific ratios to each other in order to promote the ability of the ability of the ADC to calculate the die temperature using standard components and logic of an ADC. These thermal voltages are generated and measured using integrated components of the die for which a temperature measurement is being provided, thus reducing several sources of inaccuracies in conventional die temperature measurement techniques. Addition embodiments are provided for detecting defective diodes based on comparisons of the thermal voltage outputs.

  • Patent number: 10362326
    Abstract: Motion compensation requires a significant amount of memory bandwidth, especially for smaller prediction unit sizes. The worst case bandwidth requirements can occur when bi-predicted 4×8 or 8×4 PUs are used. To reduce the memory bandwidth requirements for such smaller PUs, methods are provided for restricting inter-coded PUs of small block sizes to be coded only in a uni-predictive mode, i.e., forward prediction or backward prediction. More specifically, PUs of specified restricted sizes in bi-predicted slices (B slices) are forced to be uni-predicted.
