  • Publication number: 20240143322
    Abstract: A software developer proxy tool accesses microservice applications for a software development project by connecting the developer proxy tool to a common port on a computer network. The tool implements software and hardware to register a plurality of the microservice applications on connection ports that connect to the developer proxy tool at an address for the common port. Data requests among the microservices are handled by the developer proxy tool via the common port. The tool sequentially queries selected microservice applications on the respective connection ports to determine availability for completing a request. The tool receives responses back from microservices and directs the responses back to the requesting program. Failed requests trigger use of remote or third party microservice applications that may be available over an internet connection.

  • Publication number: 20240136864
    Abstract: A wireless power transmission device includes a transmission device and a control device. The control device generates a driving signal to the transmission device in a first soft-start period, so as to drive the transmission device. The control device measures an energy message generated by the transmission device to generate a measurement result in a measurement period, and calculates a signal parameter according to the measurement result. The control device accordingly generates a carrier signal according to the signal parameter obtained by the measurement period in a second soft-start period. In a transmission period, the carrier signal is transmitted to the wireless power-receiving device through the transmission device. The energy message is generated by the transmission device in response to a distance between the transmission device and the wireless power-receiving device.
