Patent CA-2312535-A1 (CA)
Title: Coated optical fiber with increased modulus and thermally enhanced strippability
Inventor: TORNQVIST HAKAN
IPC: C03C25/10
Filed: 2000-06-27
Abstract: In accordance with the invention, an optical fiber is provided with a protective coating having enhanced thermal characteristics for easy removal from the optical fiber. In particular, at elevated temperatures used in stripping, the delamination resistance drops to low levels substantially independent of modulus. This permits fabrication of a protectively coated fiber which has relatively high modulus and delamination resistance at room temperature but, due to its enhanced thermal characteristics, is nonetheless relatively easy to strip at elevated temperatures. Thus, for example, applicants can provide a protectively coated optical fiber or ribbon with a room temperature modulus of at least 90 psi, and a high temperature delamination resistance that is less than 40% of the room-temperature delamination resistance and preferably less than 30%.  Coatings based on a polyether backbone and non-polar monomers are preferred.

Title: Allele frequency differences method for phenotype cloning
Inventor: JOHSSON JON J
IPC: C12Q1/6809
Filed: 1999-10-26
Abstract: A general method is described for screening cDNAs, genes or genome segments to directly isolate and characterize sequences associated with particular phenotypes. In the case of the human genome, a simplification of the starting material is needed, and a specific method to generate highly polymorphic genome subsets for this purpose is presented. The general screening method identifies DNA sequences containing allele frequency differences when groups with dissimilar phenotypes are compared. The approach is based on mathematical principles of inequality. A change in the abundance ratio of homoduplexes of perfectly matched sequences to heteroduplexes of perfectly matched sequences, or, conversely, of mismatched homoduplexes to mismatched heteroduplexes, serves as an indicator of allele frequency difference.

Title: Multi-port random access memory
Inventor: WOOD STEVEN WILLIAM
IPC: G11C8/18
Filed: 1996-05-15
Abstract: A multi-port RAM (random access memory) including an array of RAM cells. Each RAM cell has a core cell with a single-ended, pseudo-differential write access port and differential, indirect access read ports.      The architecture of the features of the mufti-port RAM allows direct scaling of the number of write and read access ports to any practical limit with no adverse effects on cell stability margins and therefore data integrity. Also, disclosed is a design detail for an innovative time multiplexed read port architecture implemented as part of a high-speed 9-port time slot interchange random access memory. It provides a practical, high-speed, low-power and area efficient read port structure to allow eight random access reads per clock cycle. Because all timing is internally generated from a single rising clock transition of a system clock signal, no special control or clocking is required externally to the memory.
