摘要： A portable information handling system camera module has a single shutter that slides in response to a single shutter mechanism to manage access for a field of view of both a visual camera and an infrared camera by sliding only between first and second positions, the first position aligning an opening of the shutter with a visual camera and a shield visual camera opening, the second position blocking the opening of the shutter and extending an end of the shutter over infrared camera.

摘要： Touch sensitive input devices and routing trace configurations designed to reduce border dimensions of such devices are provided herein. The touch sensitive input devices include a touch panel having a plurality of transmit lines and a plurality of receive lines, which are arranged with the plurality of transmit lines in a grid pattern, such that a sense node is disposed on the touch panel at each intersection of the transmit and receive lines. More specifically, the touch panel includes a first subset of the transmit lines coupled to routing traces on only a first side of the touch panel, a second subset of the transmit lines coupled to routing traces on only a second side of the touch panel, and a third subset of the transmit lines coupled to routing traces on both the first side and the second side of the touch panel. Methods are provided herein for compensating for differences in routing trace path lengths, so as to provide accurate detection of touch event locations on the touch panel.

The shutter assembly is supported in a spaced relationship to the circuit board by spring biased connectors that provide power to the shutter actuator.

摘要： A webcam, a privacy shutter mechanism, and method of electrically activating the privacy mechanism are described. The privacy shutter is part of a webcam and includes privacy shutter mechanism chassis; an electrically activated coil mechanism mounted on privacy shutter mechanism chassis; a locking mechanism mounted on the electrically activated coil mechanism; a shutter plane with a shutter that locks with the locking mechanism, wherein the electrically activated coil mechanism moves the shutter plane in place to open or close the shutter; a fixture having a shutter opening attached to the privacy shutter mechanism chassis; and a shutter locking mechanism that is electrically activated to lock or unlock when the shutter is close or open.
