Patent number: 11125545Abstract: The present invention is a pyrotechnic time delay system that is improved over prior-art designs. Specifically, the system described herein comprises at least one delay element. The delay element or delay dements each have an input charge, a delay composition, and an output charge. Both the input charge and the output charge are igniter compositions and are comprised of the same components despite having different functional goals. The input charge and output charge compositions preferably contain titanium, manganese dioxide, and polytetrafluoroethylene. The delay composition may be modified from current formulations to include manganese and manganese dioxide, or tungsten and manganese dioxide. The system disclosed herein may be comprised of one delay element, or it may be modular wherein multiple delay elements are connected in series.Type: GrantFiled: February 8, 2018Date of Patent: September 21, 2021Assignee: U.S. Government as Represented by the Secretary of the ArmyInventors: Anthony P. Shaw, Jay C. Poret, Lori J. Groven, Joshua Koenig, Jason Brusnahan

Patent number: 9790093Abstract: A simplified method for synthesizing boron phosphide at high yields. The method requires mixing of boron phosphate and magnesium metal without diluents into a homogenous mixture, loosely packing the mixture at less than 20,000 psi and igniting the mixture using an energy input that is not greater than 20% of the reaction energy output to create a self-propagating high-temperature reaction wherein the boron phosphate and magnesium metal is completely burned during the reaction to synthesize boron phosphide at high yields.Type: GrantFiled: January 19, 2016Date of Patent: October 17, 2017Assignee: The United States of America as Represented by the Secretary of the ArmyInventors: Zhaohua Luan, Lauren A. Morris, Anthony P. Shaw, Christopher D. Haines, Jay C. Poret

Patent number: 5923029Abstract: A pair of interleaved finger-like electrodes are positioned over a pyro-electric sheet of polyvinylidine fluoride and a pair of coatings are formed upon the electrodes having different optical reflectance, and as a result, a light beam energy absorption differential will be produced between the coatings and the resulting change in temperature in the sheet material under the electrodes will cause a voltage to be generated. A differential amplifier is connected across the electrodes to sense this voltage, indicative of the detection of an incoming laser light beam. A light chopper is positioned to interrupt the light beam directed at a portion of the pyro-electric sheet.Type: GrantFiled: September 22, 1997Date of Patent: July 13, 1999Assignee: The United States of America as represented by the Secretary of the Air ForceInventors: Thomas R.

Patent number: 5323011Abstract: An ionizing radiation detector employs optical fibers as the medium for sensing ionizing radiation emitted by a radioactive source. Light in the infrared region is pumped continuously through an optical fiber located in an area or region where the unintentional discharge of ionizing radiation may be expected, so that such emission is detected the moment it occurs. The source of optical light emits a constant output within a specific wavelength band which changes only when irradiation of the fibers by ionizing radiation causes their internal color centers to change. The output of the fibers is optically coupled to a photomultiplier via a light pipe. A single light source, detector, and associated electronics complete the system. A hand-held unit unique for remote sensing may house these components. Due to safety conditions, these components are located at a point remote from the position liable to become under the influence of the radiation exposure field.Type: GrantFiled: August 16, 1993Date of Patent: June 21, 1994Assignee: The Johns Hopkins UniversityInventors: Joseph J. Suter, Jay C. Poret
