Publication number: 20180076894Abstract: A system comprises a tracking electromagnetic beam generator, a retro-reflecting device, a signal generator, a communication electromagnetic beam generator and a receiver. The tracking electromagnetic beam generator transmits a tracking electromagnetic beam. The retro-reflecting device reflects the tracking electromagnetic beam toward the tracking electromagnetic beam generator. The signal generator generates a communication signal. The communication electromagnetic beam generator transmits a communication electromagnetic beam, based on the communication signal, to the retro-reflecting device. The receiver receives a portion of the communication electromagnetic beam as reflected from the retro-reflecting device.Type: ApplicationFiled: September 12, 2016Publication date: March 15, 2018Inventors: Burton H.

Publication number: 20180038886Abstract: A device includes two electrically isolated metalized posts attached in close proximity to each other on a bendable substrate. When the bendable substrate bends concavely with respect to the surface onto which the posts are mounted, the distance between the tops of the two posts decreases. At a fixed bending curvature, the two posts will meet and complete an electrical circuit. The posts comprise a flexible material so that the meeting of the posts has minimal effect on the spring constant or damping coefficient of the harmonic oscillation.Type: ApplicationFiled: August 8, 2016Publication date: February 8, 2018Applicant: THE UNITED STATES OF AMERICA AS REPRESENTED BY THE SECRETARY OF THE NAVYInventors: PAUL D. SWANSON, ANDREW WANG, CHARLES H. TALLY, IV

Publication number: 20170361963Abstract: A method and system involves vacuum sealing a semi-enclosure at room temperature without requiring mechanical actions within the vacuum chamber. The semi-enclosure has an inlet channel that extends inwardly into the vacuum chamber from an exterior opening (entryway) into the semi-enclosure. An uncured entryway vacuum sealant is provided at the entryway for the semi-enclosure. A vacuum is established in the vacuum chamber until the vacuum pressure reaches a desired vacuum pressure that causes the uncured entryway sealant to be provided to the entryway for the semi-enclosure. The uncured entryway vacuum sealant is cured under vacuum pressure in the semi-enclosure in the vacuum chamber.Type: ApplicationFiled: June 13, 2017Publication date: December 21, 2017Applicant: United States of America as represented by Secretary of the NavyInventors: Paul D.

Patent number: 9705450Abstract: An oscillatory apparatus and methods of utilizing the same. In one embodiment, the apparatus comprises a force sensor having a proof mass, with one or more sensing electron tunneling electrodes disposed thereon, and a frame comprising one or more reference electron tunneling electrodes. Conductive plates disposed on the sensor base and capping wafers induce oscillations of the proof mass. The sensing and the reference electrode pairs are disposed in a face-to-face configuration, thus forming a digital switch characterized by one or more closed states. In the closed state, the switch generates triggering events, thereby enabling the sensing apparatus to generate a digital output indicative of the mass position. The time period between consecutive trigger events is used to obtain mass deflection due to external forcing. Time separation between the triggering events is based on the physical dimensions established during fabrication, thus not requiring ongoing sensor calibration.Type: GrantFiled: June 24, 2011Date of Patent: July 11, 2017Assignee: THE UNITED STATES OF AMERICA AS REPRESENTED BY THE SECRETARY OF THE NAVYInventors: Paul D.

Publication number: 20160126890Abstract: A system includes a circular oscillator suspended by a flexible support structure to a support frame, a drive mechanism configured to induce the circular oscillator into a two-dimensional drive oscillation, where the drive oscillation is modified responsive to a sense oscillation of the circular oscillator caused by an angular rotation of the support frame and the circular oscillator, and a plurality of digital proximity switches disposed around a perimeter of the circular oscillator. During the modified drive oscillation a plurality of the digital proximity switches are configured to switch between an open state and a closed state and generate a time and position output to allow for a determination of each of a plurality of variable oscillation parameters for each oscillation of the modified drive oscillation.Type: ApplicationFiled: December 4, 2015Publication date: May 5, 2016Applicant: THE UNITED STATES OF AMERICA AS REPRESENTED BY THE SECRETARY OF THE NAVYInventors: PAUL D.
