Patent number: 10509084Abstract: A magnetic resonance system, comprising at least one SQUID, configured to receive a radio frequency electromagnetic signal, in a circuit configured to produce a pulsatile output having a minimum pulse frequency of at least 1 GHz which is analyzed in a processor with respect to a timebase, to generate a digital signal representing magnetic resonance information. The processor may comprise at least one rapid single flux quantum circuit. The magnetic resonance information may be image information. A plurality of SQUIDs may be provided, fed by a plurality of antennas in a spatial array, to provide parallel data acquisition. A broadband excitation may be provided to address a range of voxels per excitation cycle. The processor may digitally compensate for magnetic field inhomogeneities.Type: GrantFiled: April 7, 2017Date of Patent: December 17, 2019Assignee: Hypres, Inc.Inventors: Masoud Radparvar, Alan M. Kadin, Elie K. Track, Richard E. Hitt

Patent number: 9554303Abstract: A system and method for dynamically changing the quality of service (QoS) for a subscriber of a cellular radio system. Bandwidth-on-Demand (BoD) enables the subscriber to dynamically switch to higher bandwidth and to enable a higher throughput. This may be for a limited time or amount of data, for example. The initiation may be by the subscriber, carrier, sponsor, or automatically by an application. The QoS increase may be dynamically priced in a kind of auction. The wireless device may contact the policy servers of a multiple network operator (MNO), which in turn contacts the Authentication, Authorization and Accounting (AAA) server in the MNO's core network. The policy server contacts the scheduler on the serving basestation which then determines whether to allocate more resources (i.e. bandwidth in the form of subcarriers, resource blocks, resource elements, timeslots) to the subscriber. The initiation may start a timer or data counter.Type: GrantFiled: July 18, 2014Date of Patent: January 24, 2017Assignee: PLUSN LLCInventors: Richard E.

Patent number: 8260144Abstract: A transceiver architecture for wireless base stations wherein a broadband radio frequency signal is carried between at least one tower-mounted unit and a ground-based unit via optical fibers, or other non-distortive media, in either digital or analog format. Each tower-mounted unit (for both reception and transmission) has an antenna, analog amplifier and an electro-optical converter. The ground unit has ultrafast data converters and digital frequency translators, as well as signal linearizers, to compensate for nonlinear distortion in the amplifiers and optical links in both directions. In one embodiment of the invention, at least one of the digital data converters, frequency translators, and linearizers includes superconducting elements mounted on a cryocooler.Type: GrantFiled: March 12, 2009Date of Patent: September 4, 2012Assignee: Hypres Inc.Inventors: Deepnarayan Gupta, Oleg Mukhanov, Richard E.
