Abstract: The invention is directed to recording, transmitting, and displaying a three-dimensional image of a face of a user in a video stream. Reflected light from a curved or geometrically shaped screen is employed to provide multiple perspective views of the user's face that are transformed into the image, which is communicated to remotely located other users. A head mounted projection display system is employed to capture the reflective light. The system includes a frame, that when worn by a user, wraps around and grips the user's head. Also, at least two separate image capture modules are included on the frame and generally positioned relatively adjacent to the left and right eyes of a user when the system is worn. Each module includes one or more sensor components, such as cameras, that are arranged to detect at least reflected non-visible light from a screen positioned in front of the user.

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.

Abstract: A method, apparatus, and manufacture for writing and annotation is provided. An image is provided on a surface. Each time invisible ink is deposited on the surface, the location of the invisible ink deposited on the surface is detected before the invisible ink vanishes from the surface. The invisible ink automatically vanishes from the surface in less than one minute from the time that the invisible ink is deposited on the surface. Location information is stored based on each detected location. The projected image is modified based, at least in part, on the stored location information.

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 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: 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: Embodiments are directed toward measuring a three dimensional range to a target. A transmitter emits light toward the target. An aperture may receive light reflections from the target. The aperture may direct the reflections toward a sensor that comprises rows of pixels that have columns. The sensor is offset a predetermined distance from the transmitter. Anticipated arrival times of the reflections on the sensor are based on the departure times and the predetermined offset distance. A portion of the pixels are sequentially activated based on the anticipated arrival times. The target's three dimensional range measurement is based on the reflections detected by the portion of the pixels.
