Patent number: 9337898Abstract: A digital intercom system provides DC power and multi-channel bidirectional digital communications over existing cabling such as microphone cabling used in analog intercom networks. Three or more conductors in the cabling are used for both transmitting and receiving digital signals and carrying DC power. The digital intercom system includes digital user stations and a digital master station which can be used to retrofit an existing analog intercom network or deployed in a new network. User stations can be connected to the cabling via drop cables which do not use active electronic components. The master station routes digital audio and control data packets in three or more channels based on respective network addresses of the user stations to provide point-to-point, point-to-multi-point, and party line communications among the user stations. Sessions and groups can be configured which define talker and listener user stations.Type: GrantFiled: November 9, 2012Date of Patent: May 10, 2016Assignee: CLEAR-COM LLCInventors: David Albiston, Nigel Gordon, David Prime

Patent number: 9071912Abstract: This disclosure relates to a portable audio test tool configured for testing an audio circuit. The portable audio test tool may replace an assortment of non-portable and/or bulky test equipment. The portable audio test tool may comprise a small and efficient troubleshooting tool that includes the functionality of multiple pieces of test equipment in a hand-held, pocket sized form. The portable audio test tool may be powered by a rechargeable power source recharged via power from a wet intercom's DC voltage power circuit cable. In some implementations, the portable audio test tool may comprise a tool connector, a tone generator, a transducer, a voltage indicator device, a power circuit, a switching device, a housing, a user interface, and/or other components.Type: GrantFiled: February 8, 2013Date of Patent: June 30, 2015Assignee: CLEAR-COM LLCInventors: Rom Rosenblum, Nigel Gordon

Patent number: 8420740Abstract: The present invention is directed to a bioadhesive thermogelling hydrogel composition for repairing and/or augmenting an intervertebral disc. The bioadhesive thermogelling hydrogel composition can be cross linked with the surrounding tissue so as to potentially serve as a nucleus pulposus replacement or augmentation along with serving to repair annular tears or fissure. The bioadhesive thermogelling hydrogel composition may include three main components: a thermal responsive polymer, an amine-containing polymer and a crosslinking component. All three components can be modified and combined in numerous ways to serve the need of the system as long as the amine-containing component is kept separate from the crosslinking component until the components are injected. The incorporation of a two-part crosslinking thermal responsive hydrogel permits smaller amounts of the crosslinking component to be used and enables the crosslinking dialdehyde to be delivered locally into the tissue that will react with the hydrogel.Type: GrantFiled: August 21, 2007Date of Patent: April 16, 2013Assignees: Synthes USA, LLC, Drexel UniversityInventors: Nigel Gordon Smith, Meredith Hans, Anthony M. Lowman, Andrea Jennifer Vernengo, Garland Fussell

Patent number: 6984201Abstract: A blood circulation assistance device (1), for location around a blood conduit (20). The device comprises: an inflatable bladder (10) moveable between a contracted form and an expanded form, for compressing the blood conduit (20) to provide counterpulsation. Pump means (30) in fluid communication with the bladder (10) move the bladder (10) from the contracted form to the expanded form. The pump means (30) comprises a centrifugal impeller (62) rotatable about an axis (61) to effect pumping. The impeller (62) is moveable axially between first and second positions to effect a reversal of the direction of pumping. Control means (50), in communication with the pump means, is capable of monitoring the cardiac cycle of an individual and triggering the pump means (30) to move the bladder (10) to the expanded form at diastole. An outer cuff, surrounds at least a portion of the bladder (10), providing an outer limiting extent to the movement of the bladder (10).Type: GrantFiled: March 24, 2003Date of Patent: January 10, 2006Assignee: Harefield Cardiac LimitedInventors: Asghar Khaghani, Geoffrey Thomas Andrews, Christopher Bowles, Nigel Gordon Smith

Patent number: 5821556Abstract: A superconductive junction (10) comprises a first track (22) of YBa.sub.2 Cu.sub.3 O.sub.7 surmounted by a second track (28) also of YBa.sub.2 Cu.sub.3 O.sub.7. An interconnect (26) in the form of a superconductive mesa electrically connects the first track to the second track and acts as a microbridge. When cooled below a critical temperature, the junction (10) shows Josephson-like behaviour. A non-superconductive layer (24) of PrBa.sub.2 Cu.sub.3 O.sub.7 separates the first track and the second track, with the interconnect extending through the PrBa.sub.2 Cu.sub.3 O.sub.7 layer in the form of an island. The junction (10) is fabricated by electron beam evaporation, optical lithography, and ion beam milling.Type: GrantFiled: September 23, 1996Date of Patent: October 13, 1998Assignee: The Secretary of State for Defence in Her Britannic Majesty's Government of the United Kingdom of Great Britain and Northern IrelandInventors: Nigel Gordon Chew, Simon Wray Goodyear, Richard George Humphreys, Julian Simon Satchell

Patent number: 4026557Abstract: A game apparatus comprises a board and playing pieces. The pieces comprise two differently colored sets. The board comprises a game zone having paths defined thereon and a central zone within the game zone. There are three sets of paths. A first set includes at least five endless paths in an expanding series from an inner endless path of the series to an outer endless path of the series. A second set includes at least five direct paths which extend directly outwards from the inner endless path to the outer endles path so that points of intersection are defined where the direct paths intersect the endless paths. A third set of at least five oblique paths form an expanding concentric series in which each path extends obliquely outwards beginning at one of the points of intersection between the inner endless path and a direct path to one of the points of intersection between the outer endless path and a direct path.Type: GrantFiled: October 7, 1975Date of Patent: May 31, 1977Inventors: Paul Antony Hammet LeBrun, Nigel Gordon Backhurst
