摘要： Electric field management techniques in GaN based semiconductors that utilize patterned regions of differing conductivity under the active GaN device, such as a GaN high electron mobility transistor (HEMT), are described. As an example, a patterned layer of oxidized silicon can be formed superjacent a layer of silicon dioxide during or prior to the heteroepitaxy of GaN or another semiconductor material. These techniques can be useful for back-side electric field management because a silicon layer, for example, can be made conductive to act as a back-side field plate.

摘要： Digital isolators operable in multiple power modes are described. The digital isolators include a low power mode, in which some circuitry of the isolator operates in a lower power state than in other mode(s) of operation or may be deactivated, and in which data communication across the isolator is not permitted. The isolator may wake from the low power mode in response to a detected event or may periodically wake. Circuitry on one side of the isolator may dictate when and how the isolator wakes from a lower power mode.

摘要： Processes for using a capacitive sensor to control drug delivery are described. The capacitive sensor measures a capacitance across a pair of electrodes arranged along either side of a container. The container includes an air chamber, a fluid chamber, and a stopper separating the air chamber from the fluid chamber. A volume of drug in the fluid chamber may be determined based on the measured capacitance. The volume is compared to a target volume, and if the volume in the fluid chamber is greater than the target volume, a stopper actuator expels a portion of the drug from the fluid chamber.

摘要： Quadrature error correction (QEC) for radio transceivers are provided herein. In certain embodiments, a transceiver includes an in-phase (I) signal path including a first controllable amplifier coupled to a first data converter, and a quadrature-phase (Q) signal path including a second controllable amplifier coupled to a second data converter. The transceiver further includes a QEC circuit operable to correct for a quadrature error between the I signal path and the Q signal path by adjusting a gain of the first controllable amplifier and/or a gain of the second controllable amplifier.

摘要： Battery monitoring techniques, which consume low amounts of power, are described herein. The battery monitoring techniques can be used when the host device (e.g., electric vehicle) is not operating, thus providing a time to use low power techniques. Measurement devices can measure system parameters when a host processor is off or in a low power mode using a heartbeat (HB) sequencing technique. Based on the HB message, the host processor can be alerted and awakened when a fault is detected.

摘要： A sensor system that obtains and processes time-of-flight data (TOF) obtained in an arbitrary orientation is provided. A TOF sensor obtains distance data describing various surfaces. A processor identifies a horizontal Z-plane in the environment, and transforms the data to align with the Z-plane. In some embodiments, the environment includes a box, and the processor identifies a bottom and a top of the box in the transformed data. The processor can further determine dimensions of the box, e.g., the height between the top and bottom of the box, and the length and width of the box top.

摘要： The battery monitoring techniques described herein may be used for detection of battery anomalies or faults. Also, the battery monitoring techniques described herein may be used to generate estimates of total battery capacity. The battery monitoring techniques may employ an alternating current frequency response (ACFR) of the battery. The ACFR response of the battery may be used to detect anomalies and/or estimate a total capacity of the battery.

摘要： One embodiment is a method for binning charge events in a photon-counting CT scanning system comprising a plurality of discriminators, wherein each discriminator is associated with a respective one of a plurality of threshold voltage levels, the method comprising detecting a transition in a signal output from one of the discriminators; and incrementing a count corresponding to the threshold voltage level associated with the one of the discriminators only if the detected discriminator output signal transition was immediately preceded by an opposite transition in the discriminator output signal.

摘要： Systems and methods for improving the efficiency of a rotational dynamic element matching (DEM) for Delta Sigma converters. In some implementations, the systems and methods are provided a for reducing intersymbol interference (ISI) of a Delta Sigma converter. A delta sigma converter architecture can include multiple I-DACs, and the output from each I-DAC can vary from the other I-DACs. Techniques are disclosed for decreasing mismatch among multiple I-DACs while improving efficiency of rotational dynamic element matching.
