    Improving A Remote Manipulator (1989)
    In:  Other Sources
    Details
    Publikationsdatum: 2019-07-12
    Beschreibung: Set of three reports describes work on Protoflight Manipulator Assembly (PFMA). "Performance Characteristics of Protoflight Manipulator Assembly" presents parameters of PFMA after refurbishment of operating components. "End Effector and Task Board Development for the Protoflight Manipulator Assembly" describes special tools and adaptations allowing PFMA to be used for servicing equipment. "Modular Software Development for the Protoflight Manipulator Assembly" documents interface and control software for PFMA.

    Interface For Color-Video Monitor (1987)
    In:  Other Sources
    Details
    Publikationsdatum: 2019-07-12
    Beschreibung: Commercially produced color-video monitor modified by addition of interface circuit to accommodate wider-than-usual range of scanning rates and resolutions. Interface circuit measures frequencies of horizontal- and vertical-synchronizing pulses. When frequencies fall within combination of preset ranges, interface generates associated preset combination of eight picture-adjusting signals. Video monitor "trained" by computer that helps to control calibration procedure and inserts values in calibration tables.

    Recursive Robot-Arm Dynamics via Filtering and Smoothing (1987)
    In:  Other Sources
    Details
    Publikationsdatum: 2019-07-12
    Beschreibung: Forward and inverse dynamics solved using Kalman filtering and Bryson-Frazier smoothing. Dynamics of serial-link robot arm solved by using recursive techniques from linear filtering and smoothing theory. Solutions of dynamical equations give forces, moments, and accelerations at joints between links, and multilink inertia matrix and its inverse. Theoretical developments lay foundation for use of filtering and smoothing techniques in design of robot controls.

    Power conditioning electronics for a 500 Wh inertial energy storage system (1989)
    In:  Other Sources
    Details
    Publikationsdatum: 2019-07-13
    Beschreibung: A description is given of a pulse-width-modulated buck-boost converter designed to interface a 500 Wh inertial energy storage system operating from 70 to 140 VDC to a constant bus of 150 VDC. Implementation of hysteresis feedback control provides excellent voltage regulation. The design is based on a 300-Wh, 94 percent Wh efficient prototype and is currently being optimized to yield 97 percent overall watt-hour efficiency.
