Abstract: A computer network teleconferencing system is provided in which audio signals are coupled to or associated with source indicators, such as source addresses in TCP protocol packets. Three-dimensional spatialization transforms are applied to audio data according to the source of such data so that, upon reproduction, a listener perceives different participants as being located in different spaced-apart locations within a 3-D spatialization region. Preferably, the user may select or modify the apparent location of the teleconference participants.

Abstract: A system projects a user-viewable, computer-generated or -fed image, wherein a head-mounted projector is used to project an image onto a retro-reflective surface, so only the viewer can see the image. The projector is connected to a computer that contains software to create virtual 2-D and or 3-D images for viewing by the user. Further, one projector each is mounted on either side of the user's head, and, by choosing for example a retro angle of less than about 10 degrees, each eye can only see the image of one of the projectors at a given distance up to 3 meters, in this example, from the retro-reflective screen. The retro angle used may be reduced with larger viewing distance desired. These projectors use lasers to avoid the need for focusing, and in some cases these projectors use instead of lasers highly collimated LED light sources to avoid the need for focusing.

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 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: Methods, systems and apparatus for providing a suspension adapted for a vehicle that moves along a surface. In response to a speed of the vehicle moving along the surface being greater than a threshold value, employing force provided by air flowing between a passenger compartment and an undercarriage to lift the passenger compartment away from direct physical contact with the undercarriage.

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: 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: 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: 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.
