Abstract: High speed, high dynamic range SAR ADC method and architecture. The SAR DAC comparison method can make fewer comparisons with less charge/fewer capacitors. The architecture makes use of a modified top plate switching (TPS) DAC technique and therefore achieves very high-speed operation. The present disclosure proffers a unique SAR ADC method of input and reference capacitor DAC switching. This benefits in higher dynamic range, no external decoupling capacitory requirement, wide common mode range and overall faster operation due to the absence of mini-ADC.

Abstract: A reference signal generator circuit can be configured to provide a temperature-compensated voltage reference signal at an output node. The reference signal generator can include a diode-connected first FET device coupled between a supply node and the output node, and a flipped-gate transistor coupled between the output node and a reference node. The reference signal generator can include a bias current source configured to provide a bias current to the output node to adjust a current density in the flipped-gate transistor relative to a current density in the first transistor.

Abstract: The present disclosure provides techniques for predicting failure of power switches and taking action based on the predictions. In an example, a method can include controlling the at least two parallel-connected power switches via a first driver and a second driver, the first a second driver responsive to a single command signal, measuring a failure characteristic of a first power switch, and disabling a first driver of the first power switch when the first failure characteristic exceeds a failure precursor threshold.

Abstract: A network node device of a communication network comprises physical (PHY) layer circuitry configured to transmit and receive data packets via a communication network; and processing circuitry connected to the PHY layer circuitry. The processing circuitry is configured to encode a data packet for sending according to a first communication protocol for sending to a second network node during a specified communication time slot, initiate resending of the data packet when the second network node does not respond during a specified acknowledge time slot, and encode the data packet according to a second communication protocol for sending to the second network node for a last retry attempt of a finite number of retry attempts, wherein the time to send the data packet formatted in the second communication protocol extends into the specified acknowledge time slot.

Abstract: Axial magnetic flux sensors are described. The axial magnetic flux sensors comprise multiple substrates with conductive traces on them in some embodiments, and in other embodiments a single substrate or no substrate. When multiple substrates are provided, the substrates couple together such that the conductive traces connect to form a coil. The coil may be a continuous, multi-loop coil. When the substrates are coupled together, they may define an opening to accommodate a shaft or other piece of equipment.

Abstract: This disclosure describes techniques to detect an object. The techniques include operations comprising: receiving an image captured by overhead camera; identifying a region of interest (ROI) of a plurality of regions within the image; selecting an object classifier from a plurality of object classifiers based on a position of the identified ROI relative to the overhead camera; and applying the selected object classifier to the identified ROI; and detecting presence of the object within the ROI in response to applying the selected object classifier to the identified ROI.

Abstract: The present disclosure provides a magnetic sensor system for monitoring the position of the rotor relative to the stator for use in electronic motor commutation. The system uses two magnetic sensors with a back bias magnet, the magnetic sensors being configured to detect changes in the magnetic field direction caused by the magnetic field interacting with two moveable targets that are being rotated by the motor shaft. The unique phase shift between the signals measured at each sensor can thus be used to determine the relative position between the stator and the rotor. In this respect, the system makes use of the Nonius or Vernier principle to measure rotational displacement, however, the scale of the encoder is defined by the number of motor pole pairs.

Abstract: There is disclosed a system for transmitting digital data with error detection, the system comprising a sender, configured to receive source data and to send transfer data, and a receiver configured to receive the transfer data and to output result data, wherein the sender is further configured to receive the source data, to numerically multiply the source data by an integer number greater than 2, and to output the multiplied source data as the transfer data, and wherein the receiver is further configured to receive the transfer data, to check if dividing the transfer data by the integer number results in an integer result, and, if the checking fails, to output an error indication, and, if the checking succeeds, to output the transfer data divided by the integer number as the result data. Also, a corresponding method is disclosed.
