Abstract: Connector receptacles having protective doors. A protective door can block a card, module, or connector insert from being inserted at an oblique angle to protect contacts in a connector receptacle from damage due to an improper insertion. The protective door can normally be closed in the absence of a card inserted in the connector receptacle. The door can be a front of a cam. A spring or magnet can bias the door in the closed position when no card is inserted. The door can be arranged to stay closed when a card is inserted at an oblique angle. When the card is inserted properly, the cam can rotate about an axis and the door can open allowing the card to access to the contacts of the connector receptacle. A second door in front of the protective door can be included to provide enhanced functionality and to provide a more uniform appearance.

Abstract: The embodiments discussed herein relate to systems, methods, and apparatus for controlling power consumption of a computing device in a standby or sleep mode. During the standby or sleep mode an external device can be plugged into the computing device. The external device can be provided power from a standby power supply until a determination is made as to whether a main power supply is operating. The determination can be based on comparing the output of the main power supply to an output of the standby power supply. If the main power supply is operating, a switch in the computing device can close to allow the main power supply to provide power to the external device. Moreover, in some embodiments, the switch can close based exclusively on a current demand of the external device from the standby power supply.

Abstract: A method and apparatus for transmitting video data over a standard personal computer bus optimizes the video data transfer rate of the bus by parsing the video data into appropriately sized and selected blocks. The video data blocks required for display are stored in a first-in first-out register, addressed, and sent over the data bus of the computer. Video data not required for display is discarded. The video data may be addressed to any location in the memory of the computer for display or further processing.

Abstract: A computer implemented process for extracting and processing information in a vertical interval of a video signal comprising a plurality of video lines selects a portion of the vertical interval from the video lines as the video lines are coupled to a computer bus, detects information stored in the selected portion, places the detected information on the bus of the computer, processes the detected information according to the portion of the vertical interval from which it is selected, and processes the video lines responsive to the detected information from the vertical interval.
