Abstract: An integrated sealed electrical connector. The connector includes a housing holding conductive elements in a row. The housing has a body, a tongue extending from the body in a mating direction, and a bracket extending from a side of the body. Each conductive element has a mating portion held by the tongue. A frame is partially embedded in and partially disposed outside the housing to, for example, mount to a board. The frame and bracket have aligned holes configured for receiving, e.g., a screw to mount to the board. Some conductive elements are configured for transmitting power and have a uniform thickness; and others are configured for transmitting signals and have a smaller thickness at the mating portion. Front and rear seals are attached to rough surfaces of the housing and conductive elements, respectively. Such techniques enable a securely sealed hybrid connector capable of reliable mating/mounting within a small space.

Abstract: A system for foreign object detection (FOD) in wireless power transfer is proposed. The system may include a balanced coil which is disposed between a transmitter coil and a receiver coil and which includes a Maxwell bridge circuit. The system may also include a temperature sensor configured to measure a temperature of the transmitter coil. The system may further include a processor configured to determine whether an FO is present between the transmitter coil and the receiver coil on the basis of voltage values detected at both ends of the bridge circuit. The FOD system can recognize the FO by finding a maximum resonant frequency at which a metal reacts using resonant frequency sweeping in a bridge circuit.

Abstract: A storage controller implemented on a System On Chip (SOC) includes an upstream functional module, a host interface, a logical to physical (L2P) interface, and a message inspection engine. The configured message inspection engine is obtained using one or more configuration settings and receives an input message from the upstream functional module. The input message is analyzed to determine a retention plan, a content modification plan, and a destination control plan. An output message is generated based at least in part on the input message, the content modification plan, and the destination control plan. If there is an affirmative content modification decision, the output message is populated with content absent from the input message. If there is an affirmative destination modification decision, the output message is populated with a destination absent from the input message. The output message is output unless there is an affirmative retention decision.
Abstract: A drive circuit, comprising: a target waveform conversion part, configured to convert target waveform information into a current or voltage signal, and output the converted current or voltage signal to a first sampling circuit and a second sampling circuit; a computational module, the computational module outputting an action command on the basis of the output results of the first sampling circuit and the second sampling circuit; and a TDC module for outputting time parameters of a counting interval on the basis of the action command outputted by the computational module. By means of the present circuit, time information of a predetermined interval can be automatically acquired, for example time information of a rising edge or a falling edge, and can then be used to calibrate emission or calibrate the final ranging result of a time-of-flight ranging solution, such that the emitted light waveform of an emission source is more accurate or the ranging result is more accurate.
Abstract: If a first group selection setting is set to TRUE, an NVM Express (NVMe) processor sends a first set of NVMe status information that includes a transfer data end event. If a second group selection setting is set to TRUE, the NVMe processor sends a second set of NVMe status information that includes an NVMe error event. A firmware functional module sends firmware status information. The aggregation module aggregates and timestamps the first and second sets of NVMe status information, if any, and the firmware status information to obtain a timestamped and aggregated message stream that is output by an interface. The timestamped and aggregated message stream enables a visualization system to analyze the NVMe processor and the firmware functional module. The NVMe processor, firmware functional module, aggregation module, and interface are in a storage controller, implemented on a system on chip (SOC), that manages a storage medium.
