摘要： Systems and methods are provided for calibrating camera and measuring offsets for reducing distortions on images. The calibrating includes aligning an on-board image sensor and a lens barrel using a kinematic mount and affixing the onboard image sensor and the lens barrel to assemble a camera. The kinematic mount provides a predetermined number of degrees of freedom in aligning the on-board image sensor and the lens barrel. A device embeds the camera. The measuring includes receiving the camera in the kinematic mount and measuring an opposing pair of offset values as measured optical centers from the lens optical axis to the image sensor pointing reference at yaw orientations of the camera at 0 degree and 180 degrees. The method determines a total offset value by taking an average of the pair and canceling the rotationally symmetrical error. The method uses the offset value for reducing distortions on images by de-warping.

摘要： An adaptive grip for a digital stylus includes a body having an internal volume and a keying feature in the internal volume to rotationally key the digital stylus to the body. The adaptive grip further includes a distal opening to allow an inking tip of the digital stylus to protrude from the internal volume and a retention feature to retain the digital stylus in the internal volume in a longitudinal direction.

摘要： Embodiments enable an accessory device coupled to a parent device to transfer heat directly to the parent device via convection thereby enabling the parent device to help cool the accessory device. The electronic device includes a device body housing coupled to and housing a heat-generating component, a device foot coupled to an exterior surface of the device body housing and a first mating element. The parent device includes a planar mounting surface, and a second mating element adapted to engage with the first mating element of the accessory device to mount the accessory device to the parent device, and brings the planar portion of the device foot housing into contact with the planar mounting surface. The heat-generating component is thermally coupled to the parent device via a thermal circuit comprising the device body house, the device foot, the planar portion thereof, and the planar mounting surface of the parent device.

摘要： The description relates to cameras and privacy covers for the cameras. One example can include a body defining a front-end and an opposing back-end that have matching profiles and a lens positioned in the front-end. This example can include an automatically self-aligning and self-retaining opaque privacy cover having a profile that matches both the front-end profile and the back-end profile of the body.
