IPC: H02H3/44
Filed: 2002-05-03
Abstract: A method of protecting a section (LINE 1) of a three phase power line uses superimposed current components (Ibs, Ics) in the power line to enable a local relay (R11) to detect operation of remote circuit breakers (B12, B21) of remote relays (R12, R21) in response to a fault on at least one phase of the power line. Line signal transducers (CT, VT) output line condition signals indicative of voltage and/or current in the line near the circuit breaker, and a signal processor in the local relay (R11) processes the line condition signals to selectively produce a fault signal for opening its circuit breaker (B11) after taking account of remote circuit breaker operation.

Title: Methods and devices based upon a novel form of nucleic acid duplex on a surface
Inventor: MITRA RAHUL
IPC: C12Q1/6837
Filed: 2002-07-11
Abstract: The present invention relates to simple method to fabricate DNA hybridization devices based upon adsorptive attachment of oligonucleotides to a positively charged surface. Such adsorbed oligonucleotide probes form a densely packed monolayer, which retains capacity for base-pair specific hybridization with a solution state nucleic acid target strand to form the duplex. However, both strand dissociation kinetics and the rate of DNase digestion suggest on symmetry grounds that solution-state nucleic acid binds to such adsorbed oligonucleotides to form a highly asymmetric and unwound duplex, with structural details that are substantially different from that known for the Watson-Crick DNA duplex. This novel nucleic acid duplex form can serve as the basis for a new class of hybridization device and methods for their use. It is also disclosed that new methods of nucleic acid duplex detection can be developed which are based upon the interaction of enzymes and dye labels with the unique structural characteristics of the non-helical duplex described herein. Preferred implementations of the invention include DNA microarrays, bead- based nucleic acid analysis, microelectronic devices to detect nucleic acid hybridization and more traditional methods of laboratory analysis, including hybridization on membranous and other solid supports.
