Abstract:
An electronic device including an illuminator and a camera configured for performing iris recognition while the user holds the device. The lens of the camera comprises four molded plastic elements with eight aspheric surfaces at a total thickness of only 3.4 mm that provides a mildly distorted image 1.2 mm across. The relative aperture is 3.5 with a fixed focal distance, providing a depth-of-field spanning a fixed focus region of at least 10 cm in depth that is 25 to 35 cm (centimeters) from the eye. The illuminator comprises a near-IR LED in a Cassegrain telescope configuration for efficient directing of flux toward the eye, thereby conserving device volume and electric energy use.
Abstract:
An f-theta lens system for a camera that provides a wide field-of-view, relatively low distortion, and a compact footprint. The lens system comprises four molded plastic elements with seven aspheric surfaces. Within a total thickness of 2.5 millimeters, the system is able to provide an image that is 1.2 millimeters across with a horizontal field of view of 127 degrees. The images produced by the system are well-suited for use with conventional face tracking algorithms designed to process rectilinear images produced by cameras with a narrower field of view.

Systems, methods, and computer-readable media are disclosed for voice-controlled multimedia devices and universal remotes. In one embodiment, an example device may include a housing, a first circuit board, a second circuit board, a first infrared light emitting diode (LED) positioned on the first circuit board and configured to emit infrared light in a first direction, a second infrared LED positioned on the first circuit board and configured to emit infrared light in a second direction opposite the first direction, a microphone disposed on the second circuit board, and an HDMI port.

Systems, methods, and computer-readable media are disclosed for voice activated devices with integrated heatsinks and speakers. In one embodiment, an example device may include a light ring, a first light emitting diode, a heatsink having a first side and a second side, and a speaker assembly coupled to the first side of the heatsink assembly. The heatsink and the speaker assembly together may form a first sealed cavity. The device may include a reflector component coupled to the second side and configured to direct light towards the light ring. The reflector component may optionally include a substantially linear member and a bent member.
Abstract:
Various approaches discussed herein enable techniques for adjusting color temperature value of illumination, for example with regard to electrophoretic ink display screens. A plurality of one type of LEDs are positioned along an injection line of a light guide panel, and are interleaved with a plurality of another type of LED positioned along the injection line. By controlling the current supplied to each group of LEDs, a color temperature value of light directed onto a display screen from the light guide panel may be adjusted to remove or reduce blue aspects.
Abstract:
Systems, methods, and computer-readable media are disclosed for display sheets with angled mirror surfaces. In one embodiment, an example display sheet may include a first layer and a plastic layer coupled to the first layer. The plastic layer may include a first portion with a first set of mirrors embossed on a surface of the plastic layer, where the first set of mirrors comprises a first tilt angle and a first roll angle. The plastic layer may include a second portion with a second set of mirrors embossed on the surface, where the second set of mirrors comprises a second tilt angle and a second roll angle. The display sheet may be configured to reflect light in a horizontal field of view and a vertical field of view with respect to a projector positioned to direct light at the display sheet.
Abstract:
A projection system projects images onto a surface as part of an augmented reality environment. Users may interact with the images and this interaction is captured as feedback to the system. The projection system includes a refractive beam steerer to direct the projected images onto specific surfaces within the environment, even if the surfaces are moved about the area. The beam steerer has multiple wedge-shaped prisms that are independently movable to steer the projected light beam as desired. Additionally, an infrared (IR) device may be used to illuminate the environment with IR light, and the IR light may be emitted along a common optical path through the refractive beam steerer as used by the projected light beam.

Systems, methods, and computer-readable media are disclosed for portable voice assistant devices with linear lighting elements. In one embodiment, an example device may include a housing having a first portion and a second portion, an elongated light bar disposed between the first portion and the second portion, and a first LED disposed within the housing. Example devices may include a reflector component configured to reflect light towards the elongated light bar, and a diffuser positioned adjacent to the elongated light bar. The diffuser may include a first curved portion and a flat portion, and the first curved portion may be substantially aligned with the first LED.
