Patent number: 10551162Abstract: Embodiments of a code modulated phased-array interferometer are described. In one embodiment, a code modulated phased-array interferometer includes a phased array having a plurality of receiver elements that receive a plurality of received signals. A code multiplexer multiplexes each of the plurality of received signals to generate a plurality of code multiplexed signals, and a combiner combines the plurality of code multiplexed signals into a combined signal. After other processing for signal reception, a code demultiplexer demultiplexes the combined baseband signal, and a complex correlator correlates unique pairs of baseband signals to generate a plurality of visibility products. Finally, the plurality of visibility products are transformed to generate an image. The concepts described herein may be relied upon to reconfigure or repurpose a phased-array receiver to achieve imaging.Type: GrantFiled: May 6, 2016Date of Patent: February 4, 2020Assignee: NORTH CAROLINA STATE UNIVERSITYInventors: Brian Floyd, Vikas Chauhan, Kevin Greene

Patent number: 10398916Abstract: A fire suppression and annunciation system using a flexible conduit and a wire rope is provided. The wire rope may be connected to a knob assembly at a universal pull station and to a release mechanism of the fire suppression system. An operator may pull a handle of the knob assembly at the universal pull station, thereby activating the release mechanism to release fire suppression agent. A flexible conduit may house the wire rope along at least a part of the connection from the universal pull station to the release mechanism. A material on the liner of the flexible conduit and/or on the wire rope may be used to reduce the coefficient of friction of wire rope in the flexible conduit. The fire suppression system may further include a pulley block system connected to the universal pull station. The pulley block system may comprise bearings, and may lower the force necessary to activate the release mechanism.Type: GrantFiled: May 26, 2016Date of Patent: September 3, 2019Assignee: Tyco Fire Products LPInventors: Michael Walter Erva, Thomas Michael Halt, Jr., Donald Marvin Bjorkman, Brian Floyd Chernetski, Dorothy Ruohonen, Steven John Benda, Mark Neumann

Patent number: 9602414Abstract: Apparatus and methods for control of bandwidth reclamation in a content distribution network. In one embodiment, the invention provides a network operator or subscriber with the ability to disable or otherwise control reclamation in a switched digital video (SDV) network. A controller uses rules in determining whether to reclaim bandwidth. These rules designate certain carriers, content, devices and/or subscribers as high priority (or protected from reclamation). In one variant, the rules determine which subscribers are queried (“pinged”) in order to evaluate whether delivered content is actually being utilized by these subscribers. Alternatively, selected ones of the devices are configured so as to generate an automatic response to any ping messages. In another variant, the rules for disabling bandwidth reclamation are entered via user interaction with an application running on a client device and in communication with the controller via a network proxy, or with the SDV server directly.Type: GrantFiled: February 9, 2011Date of Patent: March 21, 2017Assignee: Time Warner Cable Enterprises LLCInventors: Brian Floyd, Matt Smith, Stephanie Trotter

Patent number: 9453906Abstract: This invention describes circuits and methods which can allow multiple radar receiver chips to be adjusted to have very low phase offset between them. Multiple receiver chips are used in frequency-modulated carrier-wave (FMCW) radar systems for beamforming to enable angle-of-arrival measurements. FMCW radar systems are widely used in collision-avoidance and adaptive cruise control systems in vehicles, which today are operating in the 76-81 GHz frequency band. In a multi-receiver system, each receive element must have a well-controlled phase response which can be calibrated over process, voltage, and temperature. Without calibration, phase offsets can result in erroneous beamforming receiver measurements. The inventive circuit provides a technique to adjust the phase of multiple receivers across multiple chips using a single local oscillator reference and built-in-test circuitry which consist of phase shifters, a multi-frequency nonlinear phase detection circuit, and power coupling circuits.Type: GrantFiled: July 31, 2014Date of Patent: September 27, 2016Assignees: North Carolina State University, Asahi Kasei Microdevices CorporationInventors: Brian Floyd, Takeji Fujibayashi, Seiji Takeuchi
