  • Patent number: 8403528
    Abstract: An LED area light fixture for street, roadway or large area illumination including upper and lower, elongated, substantially semi-cylindrical, metallic shells spaced from and attached to each other wherein the upper shell is configured from a plurality of elongated, rectangular, angled strips with a plurality of elongated, rectangular PCB strips attached thereto and a plurality of linearly spaced high intensity LEDs embedded in each of the PCB strips and wherein the lower shell has a plurality of openings therein. A plurality of light diffusing lenses and light focusing cones are positioned in alignment with and between the LEDs and openings in the lower shell for providing uniform illumination below the LED light fixture. A heat conductive means is made integral with the PCB strips and the metallic upper shell in order to dissipate the heat generated by the high intensity LEDs during operation of the LED area light fixture.

  • Patent number: 5114391
    Abstract: Disclosed is an exercise device providing mechanical actions for independent or simultaneous exercise of the upper and lower body of a human user. Each action incorporates a mechanical movement converting output of the user to rotational motion and thereby powering one of two electrical generators. An exercise controller selects loads to be applied to the generators. The loads are coupled by the mechanical movements back to the user to provide resistance to the exercise effort. The exercise controller drives an electronic display which informs the user of his or her intensity of effort as well as the proportion of that effort being met through exercise of the upper body and the part being met through exercise of the lower body.
