  • Patent number: 10610947
    Abstract: A power supply system includes multiple power supply devices connected in common to a load. A first power supply device calculates control information for controlling voltage or current to be output to the load and controls the output to the load based on the calculated control information while transmitting the control information to a second power supply device. The second power supply device receives the control information transmitted from the first power supply device and control the output to the load based on the received control information while detecting current to be output from its own device to the load and transmitting current information to the first power supply device. The first power supply device receives the current information transmitted from the second power supply device and calculate control information based on the received current information and the current and voltage detected by its own device.

  • Patent number: 8276100
    Abstract: An input control device for enabling the user to perform predetermined operation for an icon simply by performing move operation of a pointer without button operation is provided. An operation selection area generation section 167 generates position information of an area indicating operation corresponding to selection and activation of predetermined operation for an object to be selected, and a display section 15 displays an operation selection area based on the operation selection area position information. When an operation selection determination section 168 determines that a pointer arrives at the operation selection area, it instructs a control section 19 to execute operation for the icon corresponding to the operation selection area information. Upon reception of the instruction, the control section 19 activates and executes the operation corresponding to the operation selection area.
