US Patent:

54145651, May 9, 1995

Filed:

Nov 27, 1991

Appl. No.:

7/800580

Inventors:

Mark T. Sullivan - San Francisco CA
Joseph A. Mansfield - Redmond OR

International Classification:

G02B 718

US Classification:

359872

Abstract:

A tilting kinematic mount having optics which may be precisely positioned so as to direct light or other energy to a number of measuring devices. Optic carrying tilting plates, interleaved with stationary plates are moved by linear actuators. An arrangement of balls and grooves establishes positioning of the tilting plates in a kinematic mount relative to the stationary plates, thus achieving the precise rearrangement of optical elements relative to a central axis and the redirection of the energy beam onto the sensing devices.

Abstract:

A Rotating Kinematic Mount having a rotating mirror or other optics precisely positioned so as to direct light or other energy to a number of measuring devices. The mount uses a rotating turret containing one or more tilted optical elements. The turret is raised from a base, rotated by stepper motors and then lowered into a new alignment, An arrangement of balls and grooves establishes positioning of the turret in a kinematic mount, thus achieving the precise rearrangement of optical elements relative to a central axis and the redirection of the energy beam onto the sensing devices.

Abstract:

An imaging device for imaging of a local area surrounding the imaging device. The imaging device includes a lens assembly, a filtering element and a detector. The lens assembly is configured to receive light from a local area surrounding the imaging device and to direct at least a portion of the received light to the detector. The filtering element is placed in the imaging device within the lens assembly such that light is incident at a surface of the filtering element within a range of angles determined by a design range of angles at which the filtering element is designed to filter light. The detector is configured to capture image(s) of the local area including the filtered light. The imaging device can be integrated into a depth camera assembly for determining depth information of object(s) in the local area based on the captured image(s).

Abstract:

A depth camera assembly for depth sensing of a local area includes a structured light generator, an imaging device, and a controller. The structured light generator illuminates a local area with structured light and includes an illumination source, a mounting element, and a diffractive optical element (DOE) mounted on the mounting element. The mounting element can have a plurality of adjustable positions relative to the illumination source based on emission instructions from the controller. The DOE generates, using light emitted from the illumination source, diffracted scanning beams that are projected as the structured light into the local area. A pattern of the structured light is dynamically adjustable and unique for each adjustable position of the mounting element. The imaging device captures image(s) of the structured light reflected from object(s) in the local area. The controller determines depth information for the object(s) based in part on the captured image(s).

Abstract:

A depth camera assembly (DCA) for depth sensing of a local area includes a structured light generator, an imaging device, and a controller. The structured light generator illuminates the local area with a structured light pattern. The structured light generator includes a programmable diffractive optical element (PDOE) that generates diffracted scanning beams using optical beams. The PDOE functions as a dynamic diffraction grating that dynamically adjusts diffraction of the optical beams to generate the diffracted scanning beams of different patterns. The diffracted scanning beams are projected as the structured light pattern into the local area, wherein the structured light pattern is dynamically adjustable based on the PDOE. The imaging device captures image(s) of at least a portion of the structured light pattern reflected from object(s) in the local area. The controller determines depth information for the object(s) based on the captured image(s).

Abstract:

Systems and methods for routing activity information related to objects in an external application to activity feeds associated with users in a collaboration group are disclosed. When activity information is received, it is routed to collaboration group feeds and user feeds based on a set of routing tables. The routing tables associated objects with events, containers, collaboration groups, and finally users. Based on the routing tables, users who belong to a collaboration groups that are associated with a particular object may see the activity information about that object rendered in an activity feed if the external application grants them permission to access the object. Accordingly, security associated with the object in the external application can be maintained when event information about that object is shared in an activity feed in a collaboration system.
