  • Publication number: 20230126024
    Abstract: An information handling system touch screen display and peripheral camera cooperate to coordinate presentation of visual images related to camera operations. For example, in one embodiment a tap on the camera housing commands presentation of a settings on screen display menu generated by a controller of the camera. In another example, a touch screen of the display detects a position of the camera by its capacitive effects to adjust presentation of visual images at the display, such as moving the settings on screen display menu to a position proximate the camera or adjusting a video conference presentation around the camera position.

  • Patent number: 11287083
    Abstract: An information handling system display swivel arm rotates about two axes with selectable amounts of rotation. The swivel arm couples to an anchor and a display support with a tool-less swivel coupling device having a member inserted into a housing and rotationally coupled in place by first and second pins that engage first and second slots of the member. The first slot is disposed around the circumference of the member to support substantially 360 degrees of rotation of the member in the housing. The second slot is disposed only part of the way around the circumference of the member to support partial rotation, such as 180 degrees. Removal of both pins from the member allows withdrawal of the member from the housing to disassemble the swivel arm.

  • Patent number: 10707613
    Abstract: A foldable power plug assembly may include a lever-based mechanism for retracting the metal pins of the assembly such that they do not extend beyond a top surface of a base portion of the assembly and for subsequently extracting the pins from the base portion. When a force is applied to a first pin in a folding direction while the assembly is in a deployed state, the lever-based mechanism may be configured to retract both the first and second pins toward their respective fully retracted positions. When a force is applied to the first pin in an unfolding direction while the assembly is in a retracted state, the mechanism may be configured to unfold both the first and second pins toward their respective fully deployed positions. and extend them to their fully deployed positions. The lever-based mechanism may be simple and intuitive to operate using a single hand.

  • Patent number: 7066664
    Abstract: A base for supporting a camera or other electronic device includes a body member connected by a hinge mechanism to a support member and configured to rotate about a camera tilt axis. The support member is attachable to the base of a video camera. Two front legs are fixed in position relative to the body member. A rear leg is attached by a pivot connection to the body member. The base is configured such that the rear leg may be moved by pivoting the rear leg about the rear leg pivot axis to engage a back surface of a laptop screen or flat monitor or onto a flat horizontal surface. The camera tilt axis and the rear leg pivot axis are substantially parallel.
