Title: Method and apparatus for determining the data rate of a received signal in a variable data rate orthogonal spread spectrum communication system
Inventor: WANG XIAO-AN
IPC: H04B1/707
Filed: 2000-02-07
Abstract: A method and apparatus are disclosed for determining the data rate of a received signal in a communication system utilizing code division multiple access (CDMA) techniques. The well-known Viterbi decoding-based rate detection approach is combined with the conventional repetition pattern-based rate detection approach. The hybrid approach possesses the advantages of both prior approaches, without their disadvantages. The computationally efficient repetition pattern-based data rate detection approach, while not as reliable as the Viterbi decoder-based data rate detection approach, provides reliable data rate detection most of the time. The repetition-pattern data rate detection approach is used as long as a predefined reliability metric is satisfied, and only uses the more computationally intensive Viterbi decoder-based data rate detection approach when detection reliability may be compromised. Under the hybrid rate detection scheme, a decision variable based on repetition patterns is initially formed and a decision is made on the data rate if the decision variable is in a reliable region. Otherwise, the Viterbi decoding-based rate detection scheme is employed

Patent CA-2303939-A1 (CA)
Inventor: PUNTAMBEKAR ARVIND S
IPC: H04Q11/04
Filed: 1998-09-16
Abstract: A computer network includes frame or packet-based subnetworks (S10, 511, S20 and S21) connected by switches, the switches being interconnected by high capacity trunks (T10, T11, T20 and T21) using a connection based data transfer protocol similar to Asynchronous Transfer Mode (ATM). Some of the trunks include a Permanent Virtual Path (PVP) trunk crossing an ATM core network (10), the PVP trunk including one or more bidirectional PVPs. A multi-point-to-point (MPT) protocol is used among the switches to transfer packets as groups to cells directly from "leaf", or source, switches to "root", or destination, switches without required significant routing-related processing during cell transmission. The switches allocated virtual path identifiers in a conserving manner such that (i) MPT paths from multiple leaf switches are merged to one path with a single virtual path identifier terminating at a root switch; (ii) on the PVP trunks, a virtual path identifier already allocated for an outgoing connection is allocated to an incoming connection ahead of any virtual path identifiers that are completely unallocated; and (iii) a range of virtual path identifiers is pre-provisioned at the core network access points, so that a switch connected to an access point virtual path identifiers from the pre-provisioned range on behalf of up-stream switches to extend MPTs across the core network.

IPC: A23K20/158
Filed: 2000-06-08
Abstract: A composition containing omega-3 and omega-6 fatty acids, antioxidants including vitamin E, beef flavoring, salt and starch is applied to a pet chew product made from animal hide. A method of delivering the composition to a canine's digestive system includes the steps of applying the composition to an animal hide pet chew product, such as a rawhide bone; and allowing a dog to chew the pet chew product so that the composition becomes dissolved in the dog's saliva. Once swallowed, the components of the composition are metabolized. The metabolism of the component elements is particularly beneficial to the hair and skin cells to promote growth, health and renewal of cells. More particularly, the composition improves coat shine and reduces hair loan and scaling of the animal's skin.

Title: A cluster frame synchronization scheme for a satellite digital audio radio system
Inventor: RIAZI HABIB
IPC: H04J3/06
Filed: 2000-11-24
Abstract: A satellite digital audio radio system (SDARS) transmitter provides a broadcast transmission signal including a time division multiplex (TDM) mode of transmission and a coded orthogonal frequency multiplex (OFDM) mode of transmission. The SDARS transmitter provides a transmission signal that supports four transport mechanisms or traffic channels: (1) multiple audio and data program channels (program channels), (2) a cluster control information channel (CC), (3) a global control information channel (GC), and (4) a synchronization channel (CS). In particular, the SDARS transmitter processes 100 program channels into 5 clusters, each cluster comprising GC and CS  information, along with a program cluster comprising 20 program channels and CC  information. The SDARS transmitter further partitions each cluster into 255 cluster segments and interleaves the cluster segments from each cluster for transmission. The SDARS  uses one identical maximal length PN (pseudo-random number) sequence as a cluster synchronization word for the five clusters. The relative phases of five cluster correlation results is used by a receiver to uniquely identify each individual cluster.
