US Patent:

6377618, Apr 23, 2002

Filed:

Dec 30, 1998

Appl. No.:

09/223543

Inventors:

Mohit K. Prasad - San Diego CA
Mark E. Warner - Pottstown PA

Assignee:

Agere Systems Guardian Corp. - Miami Lakes FL

International Classification:

H04B 346

US Classification:

375225, 375150, 375343, 375142

Abstract:

Rate detection of a data rate within a sequence of transmitted symbols employs correlation to calculate estimates of the auto-correlation values, or estimated coefficients, of the sequence. When the sequence of transmitted symbols includes repeated symbol values, the auto-correlation values indicate a degree of self-similarity within the sequence. A decision statistic may be formed from the auto-correlation values. The self-similarity of the auto-correlation values may be employed as a decision statistic with associated hypothesis test pair values. Various decision methods may be implemented to compare auto-correlation values to thresholds based on the hypothesis test pair values. Based on the comparison, the data rate of the sequence may be determined. Once the information is determined related to the data rate, the information may be employed by a Viterbi detector to adjust the decoding rate for decoding the symbols.

Filed:

Aug 3, 1983

Appl. No.:

6/519883

Inventors:

Carl E. Mutschler - Warminster PA
Mark E. Warner - Stowe PA

Assignee:

SmithKline Beckman Corporation - Philadelphia PA

International Classification:

G01N 3348
G06K 920

US Classification:

356 39

Abstract:

A pattern recognition system is disclosed with working area detection which automatically positions a field in a proper position with respect to an optical scanning means to optimize the pattern recognition and to automatically enable examination of the field in a good working area. The system has particular application to the examination of blood smears on a slide by enabling the positioning of the slide to enable examination of the blood smear in a good working area without operator intervention.

Filed:

Dec 10, 1996

Appl. No.:

8/762788

Inventors:

Frederic W. Buse - Allentown PA
Mark D. Warner - Chesapeake VA

Assignee:

Ingersoll-Dresser Pump Company - Liberty Corner NJ

International Classification:

F04C 1500
F16D 100

US Classification:

4182061

Abstract:

A coupling for transferring power from a drive shaft to a driven shaft includes a first coupling member, having a substantially cylindrical body, with a cylindrical bore at a first end, longitudinal key arrangement within the bore for being rotatably driven by a keyed motor drive shaft, and a solid cylindrical portion at a second end having a distal face with an alternating plurality of longitudinally projecting drive lugs and longitudinally recessed pockets; and a second coupling member for installation on a driven shaft having a substantially cylindrical body with a first proximal face, providing a non-cylindrical socket means for receiving and for drivably engaging the driven shaft, and a second distal face with an alternating plurality of longitudinally recessed pockets and longitudinally projecting drive lugs, the longitudinally projecting drive lugs of the first coupling member fitting into the longitudinally recessed pockets of the second coupling member, and vice versa, to complete the coupling. Preferably both coupling members are molded from a 30% glass filled long fiber polyphenylene sulfide resin.
