Abstract: The present disclosure relates to a method of manufacturing a light sensor comprising a matrix of pixels each associated to a micro-lens having a shift with respect to the pixel. For each axis of a plurality of axes passing by the optical center of the matric, for each pixel on the axis, and for each of a plurality light incident angles, a response value of the pixel is obtained. Based on the response values, for each axis and each pixel on the axis, a first function providing the light incident angle for which the pixel has the best response value is determined. For each axis and each pixel on the axis, a second value of the shift for bringing closer the first function to a target function is determined. The sensor is manufactured using the second values of shift.

Abstract: A system for determining a fly height includes a first head of a disk drive, a second head of the disk drive, a capacitive sensor circuit coupled to the first head and the second head, and a logic device coupled to the capacitive sensor circuit. The capacitive sensor circuit is configured to measure a first capacitance between the first head and the first disk, remove noise from the first capacitance using a second capacitance between the second head and the second disk, and based thereon determine a corrected first capacitance. The logic device is configured to determine the fly height between the first head and the first disk using the corrected first capacitance.

Abstract: A system on a chip comprising a set of one-time programmable memory elements that comprises a first valid configuration; a second valid configuration; and a plurality of invalid configurations. The system on a chip also comprises a programming indicator initially comprising a first value and configured to be permanently set to a second value. The system on a chip further comprises a decoder circuit in communication with the set of one-time programmable memory elements to determine whether the set of one-time programmable memory elements is in the first valid configuration, the second valid configuration, or any one of the plurality of invalid configurations. The decoder circuit generates a threat-detection signal when the set of one-time programmable memory elements is in any of the plurality of invalid configurations when the programming indicator is permanently set to the second value.

Abstract: A circuit includes a first capacitance array formed by n nominally equal capacitive elements. A first electrode of each capacitive element is coupled, via respective switches to either a reference voltage or ground. A differential amplifier has a first input coupled to an output of a first capacitance array, a second input grounded, and an output generating a voltage ramp. A capacitive feedback circuit couples the output of the differential amplifier to the first input. A second capacitance array has an output coupled to the first input of the differential amplifier. The capacitive elements of the first capacitance array are organized in sets. The circuit operates by controllably coupling, set by set, second electrodes of the capacitive elements of the first capacitance array to the first input of the differential amplifier.

Abstract: According to an embodiment, an LLC resonant converter includes a switching bridge having a plurality of power switches. The switching bridge is configured to receive a DC voltage input and generate a square waveform based on a pulse-modulated frequency (PFM) signal at the switching bridge. The LLC resonant converter further includes a resonant tank circuit coupled to the switching bridge. The resonant tank circuit includes a resonant inductor. The resonant tank circuit is excited in response to receiving the square waveform. The PFM signal is adjusted such that an elapsed time between a rising edge of a Drain-Source Voltage of a power switch and a zero-crossing point of current flowing through the resonant inductor falls within a predetermined range corresponding to the resonant tank circuit operating at its resonant frequency.

Abstract: A method of corrupting contents of a memory array includes asserting a signal at a reset node to thereby cause starving of current supply to the memory array, and selecting bit lines and complementary bit lines associated with desired columns of the memory array that contain memory cells to have their contents corrupted. For each desired column, a logic state of its bit line and complementary bit line are forced to a same logic state. Each word line associated with desired rows of the memory array that contains memory cells to have their contents corrupted is simultaneously asserted, and then simultaneously deasserted to thereby place each memory cell to have its contents corrupted into a metastable state during a single clock cycle.

Abstract: An example gesture detection method includes detecting at a first time a first touch on a touch panel, where the first touch covers a first area of the touch panel, and then determining whether the first touch is within a track region that surrounds a fingerprint sensing region. The method includes determining whether the first touch is within the fingerprint sensing region, the fingerprint sensing region including a sensing surface of a fingerprint sensor. The method includes determining a first fraction of the fingerprint sensing region covered by the first touch and determining whether the first fraction exceeds a first threshold. The first threshold is a majority of the fingerprint sensing region. The method includes determining a second fraction of all of the first area that is within the fingerprint sensing region and determining whether the second fraction exceeds a second threshold, where the second threshold is a fraction indicative of a majority of an area associated with the corresponding touch. The method includes based on determining that the second fraction exceeds the second threshold, determining whether the first touch is valid.

Abstract: A method includes receiving, at a master agent, announcements from candidate consumer agents indicating the presence of the candidate consumer agents. Each announcement includes display parameters for a display of the corresponding candidate consumer agent. The method further includes receiving at the master agent content parameters from a producer agent, the content parameters defining characteristics of content to be provided by the consumer agent. A mosaic screen is configured based on the received announcements and the content parameters. This configuring of the mosaic screen includes selecting ones of the consumer agents for which an announcement was received and generating content distribution parameters based on the content parameters and the display parameters of the selected ones of the consumer agents. The generated content distribution parameters are provided to the consumer agent.

Abstract: An in-memory computation (IMC) system includes an in-memory computation circuit formed by a first phase change memory (PCM) array configured to store the computational weights for an in-memory computation operation. A data storage circuit is formed by a second PCM array configured to store backup data for the computational weights for the in-memory computation operation. The first PCM array includes PCM cells made of a phase change material provided by a first GST alloy, and the second PCM array includes PCM cells made of a phase change material provided by a second GST alloy different from the first GST alloy. A control circuit operates to read the backup data from the second PCM array and write to the first PCM array to refresh the computational weights for the in-memory computation operation from the backup data.
