Patent CA-2148180-A1 (CA)
Inventor: SPURLOCK RANDY W
IPC: G06F12/10
Filed: 1995-04-28
Abstract: A video driver in a computer system is used to map a large video frame buffer into the logical address space above physical memory while the computer system is operating in WINDOWS STANDARD mode.  The requirements of the necessary address space for the frame buffer (i.e., the size of the frame buffer), and the size of physical memory are determined.  If there is sufficient address space above physical memory in which to map the frame buffer, the video driver attempts to map the frame buffer there in that address space.  The desired physical and linear addresses for the frame buffer are determined.  If the video driver detects that MICROSOFT WINDOWS is operating in standard mode, it searches memory to find the page directory that MICROSOFT WINDOWS created.  Once the page directory is found, the driver creates a new page table to map the frame buffer into the desired linear address range and adds a new entry to the existing page directory to point to the new page table.

Title: Means for detecting familial colon cancer (fcc)
Inventor: DE LA CHAPELLE ALBERT
IPC: C12Q1/683
Filed: 1994-05-02
Abstract: Markers of chromosome 2 are associated with cancer predisposition, as shown by linkage analysis, in a significant fraction of families with a history of colon and other cancers. Tumors from these patients progressed through the same series of accumulated mutations in oncogenes and tumor suppressor genes found in non-familial cases, but showed no losses of heterozygosity for the linked chromosome 2 markers. DNA from the tumors (but not normal tissues) in most familial cases revealed a consistent and distinct abnormality: rearrangemnets in short repeated sequences throughout their genomes. This abnormality suggests that a large number of replication errors had occurred during tumor development. Methods are presented for detecting the presence of the gene which predisposes people to have a colon and other tumors and for utilizing this information for diagnostic, prognostic, and preventive purposes. DNA markers useful for such methods are also described.

Title: Multistream encryption system for secure communication
Inventor: ANSHEL MICHAEL M
IPC: H04L9/14
Filed: 1994-10-04
Abstract: MUSE, a programmable multistream encrytion system for secure communication provides dynamic cryptographic security and a highly efficient surveillance mechanism for transferring very large blocks of data (VLBD) subject to real-time constraints. Encryption varies pseudorandomly in both space and Lime. MUSE allows the user to specify a finite state machine (21) which sequentially accepts parallel streams of data (VLBD) and encrypts this data in real time employing an arithmetic-algebraic pseudorandom array generator (41) (PRAG). The method of enciphering is a one-time algebraic pad system which views the incoming data streams as elements from an algebraic alphabet (finite ring) and encrypts by adding to this a pseudorandom vector sequence (21) iteratively generated from a single seed key (20). Decipherment is obtained by reversing this process.
