Patent number: 9807519Abstract: A method of analyzing performance of frequency lowering hearing aids. The method includes generating a sequentially of noise signals and transmitting acoustical sounds from a sound output device in response to the sequence of noise signals. A sound input device records the acoustical sounds and saves as a first device data. The sound input device with a frequency lowering hearing aid records the acoustical sounds and save as a second device data. The second device data is compared to the first device data and, in response to the comparison, at least one function of the frequency lowering hearing aid is optionally adjusted.Type: GrantFiled: August 11, 2014Date of Patent: October 31, 2017Assignee: The United States of America as Represented by the Secretary of DefenseInventor: Douglas S. Brungart

Patent number: 8481283Abstract: A method is disclosed for reversing fixation-induced cross-linking in tissue specimens that have been preserved for histological examination. The method involves placing the fixed tissue in a liquid under elevated temperature and pressure conditions that are sufficient to reverse the fixation-induced cross-linking, restore antigenicity to proteins, and permit improved molecular and proteomic analysis of the preserved tissue specimen. Methods are also disclosed for processing tissues for histological examination under elevated pressure conditions that enhance the perfusion of liquid reagents into the tissue and reduce overall processing times.Type: GrantFiled: September 13, 2012Date of Patent: July 9, 2013Assignees: The United States of America as Represented by the Department of Veterans Affairs, The United States of America as Represented by the Secretary of Defense on behalf of the Armed Forces Institute of Pathology, American Registry of PathologyInventors: Timothy J.

Patent number: 6643534Abstract: A system and method for optimally imaging the peripheral vasculature is disclosed which includes defining a given number of scan stations along a patient's peripheral vasculature and initially injecting a relatively small amount of contrast agent into the patient to pass a test bolus through the patient's peripheral vasculature, and thereafter tracking the test bolus through the patient and adjusting the patient on a moveable table within the MR imaging device from one scan station to a next station to determine a maximum travel time that the test bolus takes to travel through each of the given number of scan stations. Additional contrast agent is then injected into the patient to pass an exam bolus through the patient's peripheral vasculature, and using the test bolus travel time, MR data can be acquired from each scan station while it is known that the exam bolus is present in that station to optimize image resolution.Type: GrantFiled: March 13, 2002Date of Patent: November 4, 2003Assignees: General Electric Company, Uniform Services University of Health Sciences, The United States of America as represented by the Secretary of DefenseInventors: Thomas K.F.

Patent number: 5389788Abstract: An infrared (IR) radiation transducer integrates an IR detector array with a liquid crystal (LC) readout. The IR detector is preferably a pixelized bolometer array, but other detectors such as pyroelectric materials are possible. To modulate the LC in response to detected IR radiation, a modulating section is provided that includes a charge injection structure which injects electrical charge in response to the detected IR radiation, and a charge transfer structure that transfers the injected charge to the LC readout section. During its active phase the charge transfer layer is depleted of majority charge carriers, and the charge injection and transfer mechanism operates in a manner analogous to a bipolar transistor. A visible readout is obtained by directing readout light through the LC, where it is modulated in accordance with the detected IR image. The transducers are small and light weight enough to be incorporated into a pair of goggles, for which no separate cooling is required.Type: GrantFiled: December 13, 1993Date of Patent: February 14, 1995Assignees: Hughes Aircraft Company, The United States of America as represented by the Secretary of the DefenseInventors: Jan Grinberg, Raymond Balcerak, Chiung-Sheng Wu, Uzi Efron, Paul O.
