Abstract: According to an embodiment, a method for a touch scan is proposed. The method includes operating a device in first and second modes corresponding to the device, respectively, being wirelessly and not wirelessly charged. In each mode for each frame, the method includes dividing a frequency range corresponding to a touch-sensing technology into M or N positive integer numbers of equal and sequential frequency intervals, where N is greater than M. In the first mode, the method includes determining a first frequency interval of the M frequency intervals with the least noise and performing the touch scan using a first frequency within the first frequency interval. In the second mode for each frame, the method includes determining a second frequency interval of the N frequency intervals with the least noise and performing the touch scan using a second frequency within the second frequency interval.

Abstract: An electronic circuit includes image acquisition cells, wherein each cell has a photodetector coupled to a first node of the cell, and an amplifying transistor having a gate connected to the first node, a conduction node coupled to an output of the cell, and a node for controlling a back gate voltage. The amplifying transistor is configured so that its threshold voltage varies according to the back gate voltage. A control circuit adjusts a voltage applied to the control node of the back gate voltage of the amplifying transistor of one of the cells according to a comparison of the voltage present at the cell output and a reference voltage.

Abstract: An electronic device applies a frequency offset function to a first signal having a first frequency. The device includes a delay element configured to output a second signal corresponding to the first signal delayed by a duration equal to a first period of said signal divided by four. A circuit branch includes a first circuit configured to divide the frequency of the first signal by a given number coupled in series with a second circuit configured to implement an integration. The circuit branch outputs a third signal and a fourth signal. A single side band mixing circuit processes the first signal, second signal, third signal and fourth signal to generate an output signal.

Abstract: A converter circuit is configured to convert a DC voltage into an AC voltage using a first thyristor and second thyristor in series in a first branch, a third thyristor and fourth thyristor in series in a second branch in an antiparallel configuration to the first branch, and a first transistor and second transistor in series in a third branch. When the AC voltage is equal to zero, and when the first thyristor is conductive and the first and second transistors are non-conductive, a first positive current is applied to the gate of the antiparallel third thyristor to control turn on and ensure that the current circulating in the first thyristor falls below the holding current.

Abstract: Various embodiments of wafers include a polycrystalline silicon carbide (SiC) layer or base substrate. The polycrystalline silicon carbide (SiC) layer may have a resistivity less than or equal to 2 mohm-cm (milliohm-centimeter) such that the polycrystalline silicon carbide layer is a low resistivity polycrystalline silicon carbide layer. The polycrystalline silicon carbide layer may have grains with a grain size less than or equal to 1 millimeter (mm), and may have a non-columnar structure. The polycrystalline silicon carbide layer may have a warpage less than or equal to 75 μm (micrometers). A monocrystalline silicon carbide (SiC) layer may be coupled to the polycrystalline silicon carbide (SiC) layer by a bonding layer. The monocrystalline silicon carbide layer may be thinner than the polycrystalline silicon carbide layer.

Abstract: The present disclosure is directed to an optical sensor package with light shielding material covering five sides. The optical sensor package includes a transparent layer, a substrate layer, sensor elements between the transparent layer and the substrate layer, a solder mask on the side of the substrate layer opposite the transparent layer, and layer of molding material covering five sides of the optical sensor package. The solder mask and layer of molding material prevent light from entering the sides of the optical sensor package or from traveling through the substrate layer and reflecting toward the sensor elements.

Abstract: The present disclosure is directed to a device and method for human fall detection solution. Fall detection is performed by a low power inertial measurement unit (IMU) that is communicatively coupled between a pressure sensor and an application processor. The IMU includes one or more motions sensors, such as an accelerometer and gyroscope. The application processor is the main processor of the containing device. The IMU receives pressure sensor data from the pressure sensor, and executes the fall detection using both the pressure sensor data and accelerometer data.
