  • Patent number: 6259545
    Abstract: A mounting assembly for an optical scanner includes a base unit with a hole for receiving a post of a rotor unit that includes a laser light source that emits light towards a bar code symbol or other object that reflects the light to a collector also mounted on the rotor unit. Flexures connect the base unit to the rotor so that the post and hole arrangement limits translational movement of the rotor unit due to a shock force applied to the optical scanner. The flexures may be use to transmit power signals to the rotor unit and to provide monitoring signals from the rotor unit.

  • Patent number: 6169614
    Abstract: A diffractive collector for an optical scanner includes a wedged-shaped substrate having holographic grating provided on a front surface, a conical-shaped back surface, and at least one detector. Substantially parallel light is made incident upon the front surface of the substrate, and the light is diffracted within the substrate to the back surface. The wedged shaped of the collector and the holographic grating cause the light to reflect back within the substrate at such an angle that the light remains within the substrate as the light propagates to the at least one detector.

  • Patent number: 4932966
    Abstract: An accommodating intraocular lens apparatus preferably includes a lens member having a relatively flexible portion and a relatively rigid portion, with a fluid-filled chamber therebetween. The preferred intraocular lens also includes a hydraulic or other fluid accommodation provision for changing the shape or position of the flexible lens by changing the fluid pressure in the fluid-filled chamber in response to muscle movement of the eye.
