Patent CA-2147312-A1 (CA)
Title: Apparatus and Method for Dynamic Resource Allocation in Wireless Communication Networks Utilizing Ordered Borrowing
Inventor: BENVENISTE MATHILDE
IPC: H04B7/26
Filed: 1995-04-19
Abstract: A communications system and method of ordered borrowing which facilitates dynamic access to a global channel set that has been partitioned into subsets, with each cell of the system being assigned a particular subset of the channel set.  The assignment of channel subsets is performed in such a way as to respect various constraints imposed by the physical layout.  Calls originating in a cell are first assigned to the channels allocated to the base station of that cell, in an order determined by the cell.  Once the allotted channels are exhausted, i.e. in the busy state, the cell attempts to borrow channels from those allotted to the base stations of neighboring cells in a specified order.  The borrowing cell borrows a specified number of channels from each neighbor before returning to a particular cell to borrow additional channels.  The channels borrowed from a neighbor are accessed in an order which is substantially the reverse of the order in which they are accessed by the owner cell. This prescribes, for each cell, a prespecified order in which the entire set of channels may be accessed by calls originating in that cell.

Title: A multiplex control packet for digital services
Inventor: WASILEWSKI ANTHONY J
IPC: H04N7/173
Filed: 1993-11-01
Abstract: A plurality of digital services (V'1-V'N' and A'1-A'N') are carried in a multiplex data stream (162) to a plurality of remote locations. The multiplex data stream (162) comprises a continuous sequence of frames (156). Each frame (156) comprises two consecutive fields, and each field comprises a plurality of lines. A  first group of the lines in each field defines a transport layer region of that field, and a second group of the lines defines a service data region. Portions of the service data region of each field are allocated to respective ones of the video services in proportion to respective data rates of each service. A multiplex control packet is generated (104) for each field that specifies, for each service, which portion of the service data region is allocated to that service. A multiplex map (104) is transmitted with each field, and therefore, the number and location of packets may be dynamically adjusted on a per field basis.

Title: Genetically engineered glutaminase and its use in antiviral and anticancer therapy
Inventor: ROBERTS JOSEPH
IPC: A61K47/48
Filed: 1992-12-04
Abstract: DNA encoding a therapeutically suitable glutaminase has been molecularly cloned. This allows one to obtain a polypeptide which is a therapeutically suitable glutaminase free of contaminating endotoxin. It has been found that this polypeptide is a potent anti-viral agent and when coupled to an anti-tumor monoclonal antibody is a potent anti-cancer agent. The glutaminase of the present invention is particularly useful for treating lung, breast and coloncancer cells and in the treatment of HIV-infected cells.
