    Abstract: Power supply of ECUs connected to a communication network is optimally controlled so that power consumption is reduced. A transceiver/receiver converts a message of a differential signal received via a CAN bus into a digital signal. A select circuit determines whether the converted message is in a CAN format or a UART format. If it is in the UART format, the select circuit outputs a message to the UART circuit. A UART circuit determines whether the message matches a UART format. If matched, an ID determination circuit determines whether the input message is specifying a CAN ID of its own ECU. If it is the CAN ID of the ECU, the ID determination circuit outputs an enable signal to turn on a regulator and supply power to an MCU and an actuator.

  • Patent number: 9337688
    Abstract: A set of two or more modular-critical-power-distribution skids are arranged in a redundant power center configuration to supply power to electrical loads in a modular data center facility. The skids are housed in hardened buildings. The uninterruptable power supply is electrically and mechanically connected into the multiple power distribution cabinets, all of which are mounted onto a steel framed support structure, which supports a weight of those uninterruptable power supplies and power distribution cabinets. The environmental control system controls a cooling system for the modular-critical-power-distribution skids. Electrical power from the A-side and B-side connects in a redundant power configuration to electrical loads in the cooling system.

  • Patent number: 9244509
    Abstract: An uninterruptible power system and a power control system thereof are disclosed. The power control system includes the uninterruptible power system and a computer system. The uninterruptible power system supplies power to the computer system and includes an external power adaptor, a battery module, a first switch module, a second switch module, and a switching control module. When external power is input, the external power is transmitted to the computer system via the external power adaptor. When the external power is not input, the first switch module switches automatically to supply a backup power signal from the battery module to the computer system. When the external power is not input and a control signal is not received from the computer system, the switching control module controls the second switch module to electrically disconnect a connection between the computer system and the battery module.
