Patent number: 11630131Abstract: Novel electrically-isolated high-voltage sensors are provided which have low power dissipation. The sensors are formed of a circuit comprising first and second portions separated by an electrical isolation boundary with the first portion used for high-voltage, and the second portion for low-voltage. While they are decoupled electrically, they are coupled both optically and magnetically. The first portion comprises an LED which generates an optical signal corresponding to a high-voltage signal across the electrical-isolation boundary. The second portion comprises a photodiode which receives the optical signal emitted from the LED and outputs a corresponding low-voltage electrical signal.Type: GrantFiled: July 14, 2021Date of Patent: April 18, 2023Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Damian P.

Publication number: 20230099698Abstract: The chilling system provides cooling to components housed within a container by pumping propylene-glycol-water-mixture (PGWM) or equivalent through heat exchange assemblies and thermal transfer vessels. The thermal transfer vessels are filled with a paraffin-based phase change material (PCM) or equivalent solution for realizing phase change of the PCMs at selected melting points. The heat exchange assemblies are provided with thermal electric coolers for cooling the PGWM as it travels through the heat exchangers. The cooled PGWM is directed into and through a target cooling manifold of a target heat exchanger assembly to realize cooling the housed components. The system operates on direct current at under 500 watts of power and requires no Freon-type refrigerants or compressors. A microcontroller controls switches for realizing desired flow paths of the PGWM upon receiving phase change and temperature information from sensors.Type: ApplicationFiled: September 20, 2022Publication date: March 30, 2023Applicant: United States of America as represented by the Secretary of the ArmyInventors: William P.

Patent number: 11573068Abstract: A projectile with a payload protection mechanism protects, prior to and during firing, a fragile payload, where the payload must be positioned forward in the nose of the projectile, within a frangible ogive which provides little protection to rough handling, at time of downrange function. The payload protection mechanism allows the payload to move axially within the projectile, and initially slid rearward in the more robust metal body of the projectile. The payload is retained within the body by a locking and release mechanism, until the launching of the projectile triggers (by environmental forces such as setback or spin) the release of a locking and release mechanism. Unlocking the mechanism allows the payload to slide forward within the projectile into the ogive so the payload can function as required.Type: GrantFiled: May 25, 2021Date of Patent: February 7, 2023Assignee: The United States of America as Represented by the Secretary of the ArmyInventors: Jason Wasserman, William Poulos, James Grassi, Joshua Brucker
