摘要： Systems and methods for monitoring and tracking usage of a lamp and, in one example, assigning a monetary value that can be billed to an end user are provided. Examples of the lamps can communicate wirelessly in order to receive and to transmit information related to initialization, authorization, electrical power consumption monitoring, and combinations thereof. In one embodiment, the lamp transmits data a usage parameter to a service provider via a network. The service provider can aggregate the data and, in one example, assign a usage fee that describes a monetary value based on the usage parameter and generate an output that includes that usage fee.

摘要： Provided is a method and a system for multi-channel acoustic communication and sensing. For example, there is provided a system that includes a processor and a memory. The processor, when executing instructions from the memory, can perform certain operations. The operations can include classifying a motion detected near an ultrasonic receiver based on a Doppler shift observed in a signal measured by the ultrasonic receiver. The classifying can further include detecting a side lobe in a power spectrum of the signal to indicate that the motion has been detected.

摘要： This invention provides a ventilation kit adapted to be coupled to a recessed light fixture, and comprises two supporting members. The first is adapted to be coupled with at least one edge of the recessed light fixture, while the second is adapted to be coupled with the grid system of the ceiling. There is also through-hole for air circulation. Mounting the ventilation kit onto an existing recessed light fixture enables the existing recessed light fixtures to have either an air supply or air return ventilation feature. This invention also discloses a recessed light fixture assembly with either an air supply or air return ventilation feature.

摘要： A power converter comprising a first capacitor, a flyback conversion module, a soft-start module, and a feedback control module. The flyback conversion module is coupled with the first capacitor and configured to receive a first control voltage across the first capacitor. The soft-start module is coupled with the first capacitor and is configured to charge the first capacitor during a startup stage, to increase the first control voltage to an expected voltage value at the end of the startup stage. The feedback control module is coupled with the flyback conversion module and is configured to control the flyback conversion module to output a substantially constant voltage or current after the startup stage. Wherein the expected voltage value is a value of the first control voltage when the flyback conversion module outputs a substantially constant voltage or current after the startup stage.
