Title: Direct binding assay for the determination of a bacteroides organism
Inventor: SNYDER BRIAN A
IPC: G01N33/569
Filed: 1990-12-21
Abstract: A DIRECT BINDING ASSAY FOR THE DETERMINATION OF A BACTEROIDES ORGANISM                Abstract Antigens extracted from one or more serotypes of a Bacteroides microorganism are rapidly and sensitively detected when directly bound to a water-insoluble substrate.  The bound antigens are detected by forming an immunological complex on the substrate when the antigen reacts with the appropriate antibody.  The antibody-antigen complex can be detected directly or by means of a second antibody which is directed to the Bacteroides antibody.  The entire assay can be carried out at room temperature in less than about 15 minutes.

Patent CA-2052314-A1 (CA)
Title: Spread spectrum communications system
Inventor: PARTYKA ANDRZEJ
IPC: H04B1/707
Filed: 1991-09-26
Abstract: A spread spectrum communication system for direct sequence transmission of digital information having a modulation format which is particularly suitable for indoor communication within residential, office and industrial structures. The modulation format combines BPSK or MSK spreading with FM carrier modulation by data bits and a carrier frequency shift whose magnitude is related to both a chip rate and a spreading sequence length. The carrier, chip clock and data clock are all synchronous and the sequence length is an integral submultiple of the bit length. The system reduces the frequency error between the transmitter chip clock and the receiver chip clock to permit the elimination of a code phase tracking loop in the receiver to reduce the receiver complexity. The receiver has an extended dynamic range which makes possible the reception of very strong signal without an automatic gain control loop (AGC) as well as reducing the time needed for code phase acquisition. The transmission system is highly resistant to CW jamming and short distance multipath effects.
