  • Publication number: 20240169167
    Abstract: The present disclosure provides a method for anti-tampering apparatus servicing data implemented by a calculation device connected to a target device, the method comprising: identifying a contract identification code and obtaining a contract package file and a contract authentication code from at least one remote device; obtaining a microservice file corresponding to the target device from the remote device when a device embedded code of the calculation device is matching the contract authentication code; performing the microservice file to enable the target device according to the contract package file and generate an execution report; publishing the execution report to the remote device to obtain an acceptance certification code; and combining and hashing the device embedded code, the contract authentication code and the acceptance certification code to generate a hash value, and sending the hash value to a blockchain.

  • Patent number: 11934034
    Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a movable portion, a fixed portion, a driving assembly, and an assist assembly. The movable portion is used for connecting to an optical element having a main axis. The movable portion is movable relative to the fixed portion. The driving assembly drives the movable portion to move relative to the fixed portion. The assist assembly limits the movement of the movable portion relative to the fixed portion.

  • Publication number: 20090034298
    Abstract: The present invention discloses a control method and apparatus of resonant converter with low power loss at light load and standby. Based on the frequency response and loading condition of the resonant tank of a resonant converter, adjusts the switching frequency and the switching duty cycle to have a stable output voltage. Perform zero voltage switching and obtain higher converting efficiency by using the energy transfer in the resonant tank of the resonant type converter. Also have higher converting efficiency by combining with synchronize-rectify. Including: a resonant type converter, a controller of resonant type converter, and a regulated voltage mode (frequency modulation hybrid pulse width modulation, FMHYPWM) controller, and if the system specification require, a power factor correction or a double voltage rectifier circuit may be used in the advanced stage of the resonant type converter. The out put rectifier of the resonant type converter may be changed to a synchronized-rectifier.
