Abstract: A semiconductor chip is mounted to a chip mounting portion of a leadframe which further includes and one or more leads in the leadframe arranged facing the chip mounting portion. The lead lies in a first plane and the chip mounting portion lies in a second plane, the first plane and the second plane mutually offset with a gap therebetween. An electrical component (such as a capacitor) is arranged on the chip mounting portion and extends vertically between the first plane and the second plane.

Abstract: The present disclosure is directed to a device and method for generating and transmitting a TDM signal including both raw data and processed data. The device includes a sensor having a time division multiplexing (TDM) interface. The TDM interface transmits both raw data and processed data in a single TDM signal by reserving one or more slots inside a TDM frame for transmission of the processed data. The sensor also embeds additional information inside a data stream of raw data by repurposing one or more of values of the raw data as an exception code, flag, or another type of notification. The device is also enabled to transmit data, and disabled when not in use in order to conserve power.

Abstract: A phase-change memory device column decoder is divided into two portions that can be governed independently of one another, and the driving signals of the two portions are configured so as to guarantee comparable capacitive loads at the two inputs of a sense amplifier in both of the operations of single-ended reading and double-ended reading. In particular, during single-ended reading, the sense amplifier has a first input that receives a capacitive load corresponding to the direct memory cell selected, and a second input that receives a capacitive load associated to a non-selected complementary memory cell.

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: The present disclosure is directed to a device configured to detect whether the device is in a bag or being taken out of the bag. The device determines whether the device is in a bag or being taken out of the bag based on motion measurements generated by a motion sensor and electrostatic charge measurements generated by an electrostatic charge sensor. By using both distance measurements and motion measurements, the device is able to detect whether the device is in the bag or being taken out of the bag with high efficiency, accuracy, and robustness.

Abstract: A gyroscopic sensor unit detects a phase drift between a demodulated output signal and demodulation signal during output of a quadrature test signal. A delay calculator detects the phase drift based on changes in the demodulated output signal during application of the quadrature test signal. A delay compensation circuit compensates for the phase drift by delaying the demodulation signal by the phase drift value.

Abstract: An optical module includes an optical detector, laser emitter, and first and second support structures, each carried by a substrate. An optical layer includes first and second fixed portions carried by the support structures, a movable portion affixed between the fixed portions by a spring structure, and a lens system carried by the movable portion, the lens system including an objective lens and a beam shaping lens. The optical layer includes a comb drive with a first comb structure extending from the first fixed portion to interdigitate with a second comb structure extending from the movable portion, a third comb structure extending from the second fixed portion to interdigitate with a fourth comb structure extending from the movable portion, and actuation circuitry applying voltages to the comb structures to cause the movable portion of the optical layer to oscillate back and forth between the fixed portions.
