  • Patent number: 11017492
    Abstract: An apparatus for video signal switching for use with an external graphics processing unit device includes an input unit of an information processing device configured to input a first video signal from an external device comprising a graphics processing unit (“GPU”) and an input/output interface, a processing unit of the information processing device configured to output a second video signal, and a switching unit configured to determine a route for a video display signal that is output to a display unit, the route selected from an external route along which the first video signal is output to the display unit without going through the processing unit and an internal route along which the second video signal is output to the display unit. A computer program product and a system perform the functions of the apparatus.

  • Publication number: 20200341922
    Abstract: Methods, apparatus, and computer program products for protecting electronic devices are disclosed herein. One method includes detecting that a first connection terminal unit of a protection device is connected to an electronic apparatus to be protected, detecting that a second connection terminal unit is connected to an unknown device, and suppling source power to the electronic apparatus to be protected from the unknown device via a power supply terminal in a state where a data communication terminal is physically cut off. Apparatus, and computer program products that include and/or perform the methods are also disclosed herein.

  • Patent number: 10672400
    Abstract: An electronic device is attachable to and detachable from an information processing device having a mode control portion performing control for switching an operation state in which background processing is executed in a standby mode in which the display of a display portion is stopped and a low power consumption state in which the information processing device can be quickly returned to the operation state and has a light emission portion disposed so as to be visibly recognized in a state in which the display of the display portion is stopped and a lighting control portion lighting the light emission portion in the standby mode when a predetermined event to be notified to a user occurs in the background processing.

  • Patent number: 10667442
    Abstract: An electronic device having a shield structure is disclosed. The shield structure includes a conductive heat diffusion plate that is provided in a position facing a mounting surface of an electronic circuit board on which electronic components, such as a CPU, are mounted, and diffuses heat generated from the CPU, etc.; and a conductive sponge-like member that is firmly fixed to at least either the mounting surface of the electronic circuit board or a surface of the conductive heat diffusion plate which faces the mounting surface of the electronic circuit board, and is provided to separate the CPU, etc. which generate electromagnetic wave noise from antennas.

  • Patent number: 10424876
    Abstract: A connector includes a terminal having one end soldered to a substrate; an insulating member that supports the terminal; a metal case that covers a part of the insulating member and the terminal; and a metal shield that is spot-welded to the case at several positions and covers an exposed part of the insulating member. The shield includes: an upper shielding part that covers the upper plate of the case; and an inner shielding part that bends from the end of the upper shielding part and reaches the mounting face of the substrate or a position close to the mounting face and covers the substrate-inward lateral face of the insulating member. The inner shielding part has ground posts.
