Abstract: An array of diffraction-pattern generators employ phase anti-symmetric gratings to projects near-field spatial modulations onto a closely spaced array of photoelements. Each generator in the array of generators produces point-spread functions with spatial frequencies and orientations of interest. The generators are arranged in an irregular mosaic with little or no short-range repetition. Diverse generators are shaped and placed with some irregularity to reduce or eliminate spatially periodic replication of ambiguities to facilitate imaging of nearby scenes.

Abstract: Image-sensing devices include odd-symmetry gratings that cast interference patterns over a photodetector array. Grating features offer considerable insensitivity to the wavelength of incident light, and also to the manufactured distance between the grating and the photodetector array. Photographs and other image information can be extracted from interference patterns captured by the photodetector array. Images can be captured without a lens, and cameras can be made smaller than those that are reliant on lenses and ray-optical focusing.

Abstract: Described are imaging devices that employ patchworks of diffractive structures as focusing optics. Each diffractive structure best focuses light over a relatively narrow cone of incident angles, and provides suboptimal focusing for incident angles outside that cone. Different diffractive structures best focus different angular ranges, with the patchwork thus providing an overall focusable response for the relatively broad range of angles required to image a scene. Images can be captured without a lens, and cameras can be made smaller than those that are reliant on lenses and ray-optical focusing.

Abstract: The embodiments herein describe technologies of cryogenic digital systems with a power supply located in an ambient temperature domain and logic located in a cryogenic temperature domain. A pair of conductors is operable to carry current with a voltage difference between the power supply and the logic. The pair of conductors includes a first portion thermally coupled to a temperature-regulated or temperature-controlled intermediate temperature domain. The intermediate temperature domain is less than the ambient temperature domain and greater than the cryogenic temperature domain.

Abstract: A user interface includes both a touchscreen for tactile input and one or more lensless optical sensors for sensing additional, remote gestures. Users can interact with the user interface in a volume of space near the display, and are thus not constrained to the relatively small area of the touchscreen. Remote hand or face gestures can be used to turn on or otherwise alter the tactile user interface. Shared user interfaces can operate without touch, and thus avoid cross-contamination of e.g. viruses and bacteria.

Abstract: A sensing device with an odd-symmetry grating projects near-field spatial modulations onto a closely spaced photodetector array. The grating includes upper and lower features that define boundaries of odd symmetry. The features include upper and lower segments of various widths on opposite sides of each boundary, the upper segments at a height sufficient to induce one half wavelength of retardation in the band of interest relative to the lower segments. The resultant interference produces the spatial modulations for capture by the array. Photographs and other image information can be extracted from the captured data.
