  • Patent number: 7631968
    Abstract: An apparatus generally including a first housing and a second housing is disclosed. The first housing may have (i) one or more first clips configured to removably secure the first housing to a frame of eyeglasses, (ii) at least one sensor configured to sense a response of a user wearing the eyeglasses and (iii) a transceiver configured to (a) receive an image in a receive message from external of the apparatus and (b) transmit the response in a transmit message to external of the apparatus. The second housing may be (i) attached to the first housing, (ii) positionable before a lens opening of the eyeglasses on a side of the lens opening opposite the user and (iii) configured to display the image to the user through the lens opening.

  • Patent number: 5726660
    Abstract: A personal data unit (PDU) is operable to collect video information via a camera (12) and audio information via a microphone (14). The PDU (10) utilizes a cellular link for transmission of the collected information to a central station (27). Position/time information is received from a GPS satellite network (22) via an antenna (24). This allows the system to be packaged such that it can be attached to an individual and carried with that individual.

  • Patent number: 5540170
    Abstract: A multi-hull marine vessel having a center hull and a left and right outer hull movably positioned adjacent to the center hull. The outer hulls are on opposite sides of the center hull and are generally parallel to the center hull. Extendible support assemblies extend between the center hull and the outer hulls. The extendible support assemblies are movable between a retracted position with the outer hulls in nested positions immediately adjacent to the center hull, and extended positions with the outer hulls in outward positions away from the center hull. A support moving device is connected to the extendible support assemblies and is positioned to move the extendible support assemblies between the retracted and extended positions, thereby moving the outer hulls between the nested and outward positions.

  • Patent number: 5162828
    Abstract: A display system for conventional eyewear having a transparency that defines a field of view and a frame for supporting the transparency on a user's head is shown. The display system includes a light transmissive display mounted on the frame of the eyewear and optics for collimating light to project an image of the displayed information at a distance from the user in the periphery of the field of view defined by the transparency. The optics may include a single mirror that receives the information directly from the display wherein the mirror is toroidal or the like so as to project an enlarged image at an apparent optical distance from the user that is greater than the actual optical path. Alternatively, a planar mirror may be employed with a collimating lens to project the image at a desired distance from the user. The mirror may be fully reflective or partially reflective so as to superimpose the image of the displayed information on the scene viewed by the user through the transparency of the eyewear.

  • Patent number: 4757714
    Abstract: A transmitter is mounted for movement with a skier or other self-propelled sportsman and transmits ultrasonic or electromagnetic waves toward the stationary medium over which the skier or sportsman is moving. An element of the same transmitter or a separate transducer detects waves reflected from the stationary medium. A computer calculates the speed of the skier or sportsman from the Doppler shift of the reflected waves and actuates a readout unit to indicate the speed to the skier or sportsman. The readout system has a head-mounted display including a character generator and a semitransparent reflector in which the character generator is viewed so that the speed indication appears superposed over the normal background in the viewing direction.
