Apparatus And Method For Accurate Synchronization With Inbound Data Packets At Relatively Low Sampling Rates

View page
US Patent:
57844224, Jul 21, 1998
Filed:
Aug 5, 1996
Appl. No.:
8/692539
Inventors:
Douglas A. Heermann - Raymond NE
Assignee:
Transcrypt International, Inc. - Lincoln NE
International Classification:
H04L 708
US Classification:
375355
Abstract:
An apparatus and method for accurate synchronization with inbound audio data which packets at relatively low sampling rates. By using previously known information such as the time of arrival of the beginning of the data packet, a reference timer in a digital signal processor can be used to calculate a number of samples and/or portions thereof between a beginning reference time and the beginning of a data packet, and then calculate the timing error between the first sample point after the arrival of the data packet and the beginning of the data packet. Using this information, the actual arrival of the data packet can be derived and utilized to very accurately, within very small margins of error, synchronize the beginning of the data packet with the scrambling algorithm used in the receiver.

US Patent:
20180252499, Sep 6, 2018
Filed:
Mar 2, 2018
Appl. No.:
15/911052
Inventors:
- Conroe TX, US
Donald Chaffee - Crestview FL, US
Douglas Heermann - Conroe TX, US
Brian Philpot - Spring TX, US
International Classification:
F41G 7/00
H05K 1/14
F41H 11/02
Abstract:
A time domain detection system to measure and report on hypervelocity impacts HVI between an interceptor vehicle and a target vehicle. Wherein, said time domain detection system comprises a target vehicle components installed on said target vehicle, a one or more panels arranged on a portion of said target vehicle at a potential HVI locations, and a hit detection system wired into said one or more panels. Said target vehicle components comprise at least said hit detection system, and a lines. Said one or more panels are wired into said hit detection system with said lines. Said hit detection system is configured to communicate with said one or more panels over said lines. Said one or more panels can each comprise a one or more detector panel layers, and a two or more insulator layers.

US Patent:
20180113095, Apr 26, 2018
Filed:
Oct 10, 2017
Appl. No.:
15/729239
Inventors:
- Conroe TX, US
Douglas A. Heermann - Conroe TX, US
Brian D. Philpot - Spring TX, US
Assignee:
Invocon, Inc. - Conroe TX
International Classification:
G01N 29/04
F41G 7/00
G01L 5/14
F42B 12/22
Abstract:
A system and method is provided for detecting the trajectory of multiple fragments through a conic or cylindrical section, such as the body of a missile. Three or more sensors are placed on the on the body of the object. Each of the sensors is constructed and arranged to measure signals to the sensor at from impacts on one or more locations on the body. The sensor then transmits a signal commiserate with the impact of a fragment thereon. A computer system is also provided to perform necessary calculations and, potentially, record the impact times and locations. When the body of the object is hit by fragments or shrapnel, a signal from one or more of the sensors is sent to the computer system. This operation is performed and constantly updated for all locations where a fragment is detected by one or more of the sensors. Waveforms of the impacts are recorded, but because multiple hits can occur, there can be superposition (or destruction) of the resulting waveform sent to the computer system. The computer system can interpret which superposition or destruction is indicative of another fragment strike, and filter out those additions or subtractions to the waveforms that could not possibly be from another fragment.
