Title: Standing sine wave clock bus for clock distribution systems
Inventor: REYMOND WELLES K
IPC: G06F1/04
Filed: 1994-10-25
Abstract: A clock phase and frequency distribution system (10) is disclosed which uses a standing sine wave and provides substantially simultaneous significant crossing instances everywhere in the system while using low power and not requiring bus termination or precise control of the transmission path characteristics (Zo). The system is particularly advantageous in high frequency applications such as digital, linear (non-branched), backplane applications, but is also applicable to other topographies such as stars, rings and meshes. The system includes a sine wave generating (20) and driving circuit (42), a clock bus (25) and clock receivers (30a...n).  The clock receivers (30a...n) present a high impedence interference to the clock bus (25). The basic design considerations and parameters which limit and define performance include the maximum propagation delay between any two points in the system, the total low frequency capacitance of the system, and the Q of the system which must be high at the frequency of the standing wave in order to satisfy low power and simultaneity objectives. To overcome system length limitations, embodiments utilizing master and slaves are provided, where phase feedback is provided to the slaves. Multifrequency systems are also provided.

Granules of a second color (19) or color blend are then deposited on the strip (13, 58) by dropping on tacky second areas (17) between the spaced first areas (16). If desired, one or both edges of the second color granule (19) drops also may be trimmed, the second color granules (19) may be deposited on only a portion of the tacky strip areas (17) between the spaced first areas (16), and additional color granules may be applied to the remaining tacky areas to form shingles with three or more colored areas.

Title: Monoclonal antibody to oncofetal protein for treating and detecting cancer
Inventor: SCHUMM DOROTHY E
IPC: A61P35/00
Filed: 1995-03-31
Abstract: The present invention provides a low cost, less toxic, anti-cancer immunotherapy which enhances the host's immune system ability to destroy or contain cancers, and also provides a diagnostic test for cancer. Specifically, the present invention provides monoclonal antibodies specific for, that is, specifically bind, oncofetal protein (OFP), a cancer cell product. Tumors treated with a single dose of the monoclonal antibodies against OFP are markedly reduced in size, and leukemic populations of cells treated with a single dose of monoclonal antibodies against OFP are significantly decreased in number. Since the monoclonal antibodies of the present invention do not bind to tumor cells, the monoclonal antibody treatment overcomes the disadvantages associated with tumor cell targeting. Monoclonal antibodies to OFP offer a simple and inexpensive agent for use as a primary or adjuvant therapy against a wide variety of cancers and tumors in humans and other animals. The monoclonal antibodies against OFP are also employed to detect cancer in animal, including human patients.

Inventor: HORSTEIN MICHAEL
IPC: H04B7/26
Filed: 1996-10-02
Abstract: A method of controlling communication satellite system capacity in a satellite-based cellular telecommunication system where two or more communication satellites provide coverage of a service region.  Communication satellites are assigned to mobile cellular stations in a manner designed to minimize the maximum single-satellite power that is required for the communication satellites collectively to supply a specified number of transmissions to the service region. The service region may be divided into grids, where each grid is characterized by a number which is proportional to the average number of active mobile cellular stations.  This information, in conjunction with a power utilization factor associated with each satellite/grid pair, is used to determine the assignments of the communication satellites to the mobile cellular stations.
