  • Publication number: 20070129601
    Abstract: The present invention provides scanning beam devices that have one or more detectors positioned within a housing of the device. The detector(s) may be disposed anywhere within the housing to receive light reflected from the target area. In one embodiment, an optical assembly of the device transmits a first portion of the reflected light to a scanning element, and a second portion of the reflected light to the detectors. In another embodiment, the optical assembly is configured to transmit substantially all of the reflected light to the scanning element. In such embodiments, the scanning element will be adapted to allow the light to exit the scanning element and impinge on the detector(s) within the housing.

  • Publication number: 20070091426
    Abstract: The present invention provides methods and systems for scanning an illumination spot over a target area. The present invention removes stored energy from a scanning element to stop the scanning element from vibrating and to substantially return the scanning element to its starting position so as to enable high frame rates.

  • Publication number: 20070019906
    Abstract: Methods and system for counterbalancing accelerations and/or torques caused by actuation of an actuation element and a scanning element. A scanning beam device may comprise a counterbalance to generate forces and/or torques that are substantially equal and substantially opposite to the forces and/or torque generated by the scanning of the actuation element.

  • Publication number: 20060226231
    Abstract: The present invention provides methods, software, and systems that allow a scanning beam device to create full or partial color images using sequential color methods. The methods of the present invention may use sequential color concepts to improve image generation without increasing scan rates while using light source modulation rates that are much less than conventional methods.

  • Publication number: 20060077121
    Abstract: Apparent distance of a pixel within an optical field of view is determined. Incoming light is scanned along a raster pattern to direct light for a select pixel onto a light distance detector. The distance is sampled for each pixel or for a group of pixels. The light distance detector includes a concentric set of rings sensors. The larger the spot of light corresponding to the pixel, the more rings are impinged. The diameter of the spot is proportional to the distance at which the light originated (e.g., light source or object from which light was reflected). Alternatively, a variable focus lens (VFL) adjusts focal length for a given pixel to achieve a standard spot size. The distance at which the light originated correlates to the focal length of the VFL.

  • Patent number: 6071214
    Abstract: An exercise device comprising a first grip and a second grip, both the first grip and second grip having a longitudinal grip and a transverse grip, the longitudinal grip having a longitudinal diameter and the transverse grip having a transverse diameter greater than the longitudinal diameter, the second grip being torsionally connected to the first grip such that the longitudinal grips are adjacent and such that the torque required to rotate the first grip relative to the second grip can be adjusted via a threaded arrangement.
