Title: High Data Rate Satellite Communication System
Inventor: ROSEN HAROLD A
IPC: H04B7/208
Filed: 1994-10-20
Abstract: A satellite-based communication system (10) providing high rate transfer of data between linked terminals (11, 12). The system (10) comprises a plurality of user terminals (VSAT's) (111, 12) that are linked by and that communicate with each other by way of a satellite- based relay system (13). A network control center (14) provides configuration signals that control the satellite relay system (13) and coordinate linking of terminals (111, 12) to each other. Frequency division multiplexing uplinks are used from the terminals (111, 12) and the network control center (14) to the satellite relay system (13). Time division multiplexing are used on downlinks from the satellite relay system (13) to the terminals (11, 12) and the network control center (14). Each user terminal (111,12) comprises a data compression and decompression circuit (22), a transceiver (23), and an antenna (25) for transmitting and receiving data to and from the satellite relay system (13). The satellite relay system (13) comprises a satellite (30), a wide area antenna (35), a plurality of receive antennas (32, 24), a plurality of transmit antennas (31, 33), and a signal processor (36). The wide area antenna (35) is provided for communicating command and control signals between the user terminals (11, 12) and the network control center (13). The plurality of receive antennas (32, 34) operate in a first frequency band and produce a first plurality of beams that cover a service area. The plurality of receive antennas (1332, 34) receive time domain modulated data from the user terminals (11, 12). The plurality of transmit antennas (31, 33) operate in a second frequency band and produce a second plurality of beams that cover the service area. The plurality of transmit antennas (31, 33) transmit frequency domain modulated data to the user terminals (11, 12). The signal processor (36) demodulates the time domain modulated data received from a user terminal (11), routes the demodulated data so that it is transmitted to a second user terminal (12), remodulates the data to provide frequency domain modulated data, and transmits the frequency domain modulated data to the second user terminal (12). Video cameras (21) and monitors (24) are coupled to the user terminals (11, 12) to provide for video teleconferencing.

Patent CA-2120645-A1 (CA)
Title: Compressively resilient loop structure for hook and loop fastener systems
Inventor: BURNES ANDREW S
IPC: A44B18/00
Filed: 1994-04-06
Abstract: The present invention relates to an improved loop portion of a hook and loop fastening system. The loop portion is a two-layer composite including a compressively resilient backing material and a layer of fibrous loop material. The loop material is placed adjacent the bottom surface of the backing material and then a plurality of the loop fibers are needled or stitched through the backing material to form a plurality of loops which project above the top surface of the backing material. Due to the resilient nature of the backing material, when a hook member is brought into engagement with the loop material, the backing material compresses thereby exposing a greater portion of the individual loops for engagement with the hooks. Once the hooks have been engaged, the backing material expands back to make the exposed portion of the loops smaller. As a result, more individual engagements between hook and loop elements occur and there is less play between the hook members and loop elements thereby yielding a more firmly engaged hook and loop system as evidenced by increased peel strengths when compared to conventionally-backed loop structures. To add increased strength to the structure, the layer of loop material may contain an adhesive to bond the fibers and more firmly anchor the loops so as to lessen the chance of their disengagement during separation of the hook members from the loop members.      Lastly, the adhesive employed may be a pressure-sensitive adhesive to permit the adherence of the loop structure to another substrate such as a diaper outercover.

Filed: 1994-11-28
Abstract: It is a purpose of the present invention to connect the operation of the driving-force distributing device with the operation of the driving-force suppressing device at an appropriate timing to insure a stable performance of the vehicle. When a slip rate exceeds a predetermined value, a driving-force distributing device which includes a variable differential operation limiting device is first operated so as to hold a differential operation limiting torque at a predetermined value. If the slip rate further increases, a driving-force suppressing device which includes a traction control device is operated so as to hold the engine output at a predetermined value. At that time, if slip rates of both racing inner wheel and racing outer wheel are further increased, the driving-force suppressing device is operated to reduce the engine output.

Title: Enriching and identyfing fetal cells in maternal blood for in situ hybridization
Inventor: ASGARI MORTEZA
IPC: G01N33/58
Filed: 1993-07-19
Abstract: To provide in situ hybridization assays in which the sex of a fetus, genetic characteristics or abnormalities, infectious agents or identification of other chemical, biochemical or genetic properties are detected by nucleic acid hybridization of fetal cells, such fetal cells, which circulate in maternal blood, are enriched, detected and interrogated. The techniques are capable of detecting a single genetic abnormality in a single cell, involving as few as approximately 75 base pairs, by visual microscopic ex-amination. Genetic abnormalities may include deletions, additions, amplifications, translocations or rearrangements. Multiple abnormalities may also be detected simultaneously, and they may be visually distinguished by color. Cells may be obtained from amniocentesis, chorionic villi sampling, or in vitro fertilization embryos or products of conception, but are preferably from mater-nal peripheral blood. Fetal cells such as lymphocytes, erythrocytes or trophoblasts may be enriched from maternal blood.  Eryth-rocytes may be enriched by removing maternal white blood cells with an immobilized antibody to a cell surface antigen, e.g.  CD45. Fetal cells may be enriched by density gradient centrifugation. Fetal cells are desirably distinguished from maternal cells by staining, e.g. with a labeled antibody to cytokeratin or to fetal hemoglobin of for fetal hemoglobin by hematoxylin/eosin, or by in situ hybridization to detect one or more fetal mRNAs, e.g., fetal hemoglobin or fetoprotein. Kits are provided for the disclosed procedures.
