Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A full load test system of an electrical power converter and the test method thereof is disclosed. The full load test method of the electrical power converter comprises the following steps: (a) providing a power converter under test (PCUT); (b) configuring the PCUT in/on a test circuit; (c) serially connecting the PCUT with at least one bidirectional power converter in the test circuit; (d) connecting the test circuit to an alternating current low voltage three-phase power source; and (e) performing a test of the PCUT under full-load condition.

Abstract: The present invention discloses a vessel power safety control system and operating method thereof. The vessel power safety control system includes a load power management module, a real-time monitoring module, an integration module and a power module. The present invention can assist the autonomous ship as any occurrence of fault during navigation. Once the accident occurs, the load power management module will give an instruction to control the DC bus to switch from closed circuit to open circuit to protect other equipment. After determining whether the errors of the equipment on board is eliminated, the load power management system performs automatic system reset procedure. As such, the DC bus can be converted from an open circuit to a closed circuit to restart the power supply for the facility.

Abstract: A multi-party communication control system and charge process of a DC charging system is provided. According battery pack information transmitted by a battery control system, a multi-party communication control device determines a charge current or a charge voltage and a voltage-controlled charge mode required by a battery pack. The multi-party communication control device then translates the charge voltage or the charge current to a CHAdeMO language that is next transmitted to a CHAdeMO charger.
