Publication number: 20220263568Abstract: A method including configuring, an Iridium antenna of a deck box device, to receive satellite communications based in the L band frequency range, establishing a point-to-point connection with an L-band satellite communication device via a gateway device, the L-hand satellite communication device configured to receive sampled data from one or more sampling devices and receiving, by the Iridium antenna, one or more data messages from a respective sampling device via the established point-to-point connection. The method including parsing the Short Burst Data packets of each data message to retrieve the sampled data, converting, the retrieved sampled data from each respective data message into a common format, determining, one or more characteristics associated with the converted sampled data, generating a visualization based on the one or more determined characteristics, and actuating a strategic operation associated with the one or more sampling devices based on the generated visualization.Type: ApplicationFiled: February 18, 2022Publication date: August 18, 2022Applicant: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Blake J. Landry, Adam Trahan, Samuel Bateman, Charles R. Key

Publication number: 20220107401Abstract: A method for a distributed clock system (DCS) device that includes receiving a GPS signal, determining that a first current time equals a predetermined start time, and generating a shifted GPS signal by applying a configurable delay to the received GPS signal, the shifted GPS signal alternating between a low value and a high value. The method includes responsive to a falling edge of the shifted GPS signal, generating an ARM signal having a rising edge after a falling edge of the shifted GPS signal, and responsive to the ARM signal being high and the shifted GPS signal being high, generating an output enable signal. The method includes transmitting, while the output enable signal is high, a triggering signal, the triggering signal having one or more synchronizing pulses that cause one or more sampling devices to sample data according to the frequency associated with the raw clock signal.Type: ApplicationFiled: October 1, 2021Publication date: April 7, 2022Applicant: The Government of the United States of America, as represented by the Secretary of the NavyInventors: Blake J. Landry, Charles R. Key

Patent number: 7087302Abstract: The present invention relates to a sizing composition for use on glass fibers which are used to reinforce plastic resins used in the formation of fiber-reinforced plastics (FRPs). The sizing composition comprises a copolymer formed from at least one functional monomer that is selected from the group consisting of hydroxy, phenyl and alkoxylated functional groups. The glass fibers sized with the sizing composition of the invention have excellent computability with resins used in forming FRPs, as seen by a low level of white glass.Type: GrantFiled: February 24, 2003Date of Patent: August 8, 2006Assignee: Celanese International CorporationInventors: Charles R. Key, Rajeev Farwaha
