Abstract: Devices, modules, and methods enable a mobile device to change from a standby mode with low power consumption to an active mode with relatively higher power consumption, upon recognizing that a received image is substantially similar to a visual signature. The visual signature is based on an image, such as the face of the intended user, is stored in a memory. When later the mobile device is in the standby mode, it periodically performs a low power peek with a camera to receive an image of the area in front of the mobile device. If the received image is recognized as substantially related to the visual signature, the mobile device is enabled to change from the standby mode to the active mode.
Abstract translation: 当识别出接收到的图像基本上类似于视觉签名时，设备，模块和方法使得移动设备能够从低功耗的待机模式改变为具有相对更高功耗的活动模式。 视觉签名基于诸如预期用户的面部存储在存储器中的图像。 当稍后移动设备处于待机模式时，它周期性地使用相机执行低功率窥视以接收移动设备前面的区域的图像。 如果接收到的图像被识别为与视觉签名基本相关，则移动设备能够从待机模式改变为活动模式。

Abstract: A scanning light imaging device for continuously pseudo randomly scanning patterns of light in a beam onto a remote surface to achieve spatio-temporal super resolution for finding remotely located objects. The scanning light imaging device employs a scanner to project image beams of visible or non-visible light and/or tracer beams of non-visible light onto a remote surface or remote object to detect reflections. The device employs a light detector to sense at least the reflections of light from one or more of the image beams or the tracer beams incident on the remote surface or remote object. The device employs the sensed reflections of light beams to predict the trajectory of subsequent scanned beams in a pseudo random pattern and determine up to a six degrees of freedom position for the remote surface or remote object.

Abstract: A three-dimension position tracking system is presented. The system includes transmitters and receivers. A transmitter scans continuous or pulsed coherent light beams across a target. The receiver detects the reflected beams. The system recursively determines the location of the target, as a function of time, via triangulation and observation of the time-of-flight of the incoming and outgoing beams. The transmitter includes ultra-fast scanning optics to scan the receiver's field-of-view. The receiver includes arrays of ultra-fast photosensitive pixels. The system determines the angles of the incoming beams based on the line-of-sight of the triggered pixels. By observing the incoming angles and correlating timestamps associated with the outgoing and incoming beams, the system accurately, and in near real-time, determines the location of the target. By combining the geometry of the scattered beams, as well as the beams' time-of-flight, ambiguities inherent to triangulation and ambiguities inherent to time-of-flight location methods are resolved.

Abstract: A LIDAR system includes a scanner; a receiver; and one or more processor devices to perform actions, including: scanning a continuous light beam over the field of view in a first scan pass; detecting photons of the continuous light beam that are reflected from one or more objects; determining a coarse range to the one or more objects based on times of departure of the photons of the continuous light beam and times of arrival of the photons at the receiver; scanning light pulses over the field of view in a second scan pass; detecting photons from the light pulses that are reflected from the one or more objects; and determining a refined range to the one or more objects based on times of departure of the photons of the light pulses and times of arrival of the photons at the receiver.

Abstract: Methods and systems for navigating a vehicle along a surface employ a scanner to scan a light beam over the surface; employ light reflected by one or more fiducial markers on the surface onto pixels of a receiver to determine a spatial arrangement of the fiducial markers on the surface; and compare the spatial arrangement of the fiducial markers with a predetermined map of the fiducial markers to determine a location of the vehicle.

Abstract: A system to scan a field of view with light beams can include a scanning mirror arrangement having a mirror and a drive mechanism configured to rotate the mirror about an axis between two terminal positions; at least one light source configured to simultaneously produce at least a first light beam and a second light beam directed at the mirror from different directions. Upon rotation of the mirror, the first and second light beams can scan a field of view. The scanning mirror arrangement may include a mirror; hinges attached at opposite sides of the mirror; and a drive mechanism attached to the hinges and configured to twist the hinges resulting in a larger twist to the mirror, wherein the hinges are disposed between the drive mechanism and the mirror.

Abstract: Embodiments are directed toward a scanning LIDAR system that measures a distance to a target that reflects light from a transmitter to a receiver. A light transmitter is arranged to scan pulses of light that reflect off a remote surface (target) and illuminate fractions of the Field of View (FoV) of a receiver, such as a camera. These fractions of the FoV are smaller than a resolution provided by an array of pixels used to detect Time of Flight (ToF) reflections of the scanned pulses of light from a remote surface. The exemplary scanning LIDAR system may resolve an image of the remote surface at substantially higher resolution than the pixel resolution provided by its receiver.

Abstract: An image projection device for displaying an image onto a remote surface. The image projection device employs a scanner to project image beams of visible light and tracer beams of light onto a remote surface to form a display of the image. The device also employs a light detector to sense at least the reflections of light from the tracer beam pulses incident on the remote surface. The device employs the sensed tracer beam light pulses to predict the trajectory of subsequent image beam light pulses and tracer beam light pulses that form a display of the image on the remote surface in a pseudo random pattern. The trajectory of the projected image beam light pulses can be predicted so that the image is displayed from a point of view that can be selected by, or automatically adjusted for, a viewer of the displayed image.
