  • Patent number: 10248846
    Abstract: An image obtaining section 106 obtains an imaged image from an imaging device. A face authenticating section 132 detects a face image of a registered user present in the imaged image using face identifying data retained in a registered user information retaining section 180. A damage determining section 142 determines whether or not the face identifying data read from the registered user information retaining section 180 by a face data reading section 130 is damaged. If the face identifying data is determined to be damaged, a notifying section 144 notifies that the face identifying data is damaged.

  • Patent number: 10199833
    Abstract: Electronic devices may have several power supplies. Current from the power supplies may be provided to multiple loads, such as motors, processors, or other devices. When a current demand of one or more of the loads increases, current from the power supplies may be provided to meet the increased current demands of the one or more loads. To determine how much current can be provided to the loads from the power supplies, output currents of the power supplies can be determined, and a feedback voltage can be generated based on the output currents. The feedback voltage can be compared against hysteretic voltages to determine how much current may be transferred from the power supplies to the loads to compensate for the current demands of the loads.

  • Patent number: 10078483
    Abstract: A dual display client apparatus includes a pair of display housings. When physically coupled together in a first mode of operation, the display housings may be arranged as a single portable electronic device such as a clamshell laptop. In this mode, the system is configured to share computing power and other resources among the two housings, providing a more powerful and robust device than when the housings are separated. Processor power and storage capacity may be aggregated in the unitary apparatus. Battery charging and power sharing may be enabled between the devices' power supplies. When decoupled, the separate display housings are configured to each operate as a self-sufficient, standalone computing device. In this mode of operation, applications and other software may be instantiated as shared instance or separate instances, giving the user of each device ultimate flexibility in device operation and content consumption.
