Abstract: A two part signal acquisition process includes a parallel signal detection process and signal verification/false alarm rejection process. A massively parallel architecture of acquisition correlators search a large region of the time-frequency uncertainty during the parallel signal detection process to identify the most likely detections for each search dwell. Concurrent with the parallel signal detection process performed by the acquisition correlators, the current list of most likely detections is examined with additional search dwells in the verification/false alarm rejection process. The verification/false alarm rejection process is performed by a plurality of independent correlators or tracking channels. Under software control, the tracking channels perform repeated dwells on the most likely detections until they can be dismissed as false alarms or verified as the desired signal.

Abstract: A combination finger and ring sizing device consists of a planular plastic body having a first portion with a plurality of openings formed therein and a second elongated portion that is integrally joined with the first portion and that extends outwardly therefrom terminating in a free end. The openings in the first portion sequentially graduate in diametrical size and define graduated ring sizes. The openings are identified as to ring size by indicia imprinted adjacent to the openings. The elongated second portion is formed with a tapered configuration that extends away from the free end of thereof and it includes a plurality of imprinted indicia designating ring sizes.
