The DCA is moved from the first pose to a second pose, where a second portion of the local area is viewable and overlaps with the first portion. The overlapping region is not illuminated by the DCA. A non-overlapping portion of the second portion is illuminated, captured, and depth information determined.

Abstract: A slider has a drum with alternating alpha and beta grooves, first stacked pulleys, and second stacked pulleys. First and second end pulleys are at opposite ends of the slider. A line wraps as a loop from the last beta groove, around the first end pulley, to the last alpha groove, back and forth around the first stacked pulleys, off the first alpha groove, around the second end pulley, to the first beta groove, back and forth around the second stacked pulleys, and back to the last beta groove. When the drum or the end pulleys are driven, the difference in circumferences of the grooves causes the slider to move toward one of the first or second end pulleys.

Abstract: A depth camera assembly (DCA) includes a direct time of flight system for determining depth information for a local area. The DCA includes an illumination source, a camera, and a controller. The illumination source projects light (e.g., pulse of light) into the local area. The camera detects reflections of the projected light from objects in the local area. Using an internal gating selection procedure, the controller selects a gate window that is likely to be associated with reflection of a pulse of light from an object. The selected gate may be used for depth determination. The internal gating selection procedures may be achieved through external target location and selection or through internal self-selection.

Abstract: Forming features in the surface of a bicycle component involves depositing a substance onto a substrate in a geometric pattern to form a transfer medium. Forming features may also involve positioning the transfer medium relative to an unformed bicycle component, and forming a negative of the geometric pattern in the bicycle component through the application of heat and/or pressure to the transfer medium and the unformed bicycle component. The transfer medium may be configured for use in the molding of carbon fiber reinforced plastic (“CFRP”) bicycle components and may include a substrate formed of a flexible material, and a geometric pattern formed of a hard material, the hard material different than the flexible material.
