Fleming Robert Alan, Kushner Cherie Elaine: Spread spectrum localizers. Aether Wire & Location, May 14, 1997: EP0772813-A1

A network of localizers determines relative locations in three-dimensional space to within 1 cm by cooperatively measuring propagation times of pseudorandom sequences of electromagnetic impulses. Ranging transmissions may include encoded digital information to increase accuracy. The propagation time ...

Fleming Robert Alan, Kushner Cherie Elaine: Spread spectrum localizers. Aether Wire & Location, BALDWIN Stephen E, February 8, 1996: WO/1996/003689

A network of localizers (100) determines relative locations in three-dimensional space to within 1 cm by cooperatively measuring propagation times of pseudorandom sequences of electromagnetic impulses. The propagation time is determined from a correlator (114) which provides an analog pseudo-autocor ...

KUSHNER CHERIE, FLEMING ROBERT, MCALLISTER WILLIAM H, ZDEBLICK MARK: PROCEDES, DISPOSITIFS ET SYSTEMES DE RECEPTION ET DE DECODAGE DE SIGNAL EN PRESENCE DE BRUIT A LAIDE DE TRANCHES ET DUNE DISTORSION, METHODS, DEVICES AND SYSTEMS FOR RECEIVING AND DECODING A SIGNAL IN THE PRESENCE OF NOISE USING SLICES AND WARPING. PROTEUS DIGITAL HEALTH, PROTEUS DIGITAL HEALTH, RIDOUT & MAYBEE, June 20, 2017: CA2924815

A method may comprise receiving and sampling a signal. The signal may encode a data packet. A slice may be generated and stored comprising a pair of values for each of a selected number of samples of the signal representing a correlation of the signal to reference functions in the receiver. The pres ...
