Title: Method and apparatus for treating materials with electrical fields having varying orientations
Inventor: WALTERS RICHARD E
IPC: C12N15/87
Filed: 1997-06-10
Abstract: The object of the invention is to provide a method and apparatus for treating membrane containing material with electrical fields and with an added treating substance. With the method, a plurality of electrodes (121-128) are arrayed around the material to be treated and are connected to outputs of an electrode selection apparatus (110). Inputs of the electrode selection apparatus are connected to outputs of an agile pulse sequence generator. A treating substance is added to the membrane-containing material. Electrical pulses are applied to the electrode selection apparatus and are routed through the electrode selection apparatus in a predetermined, computer-controlled sequence to selected electrodes in the array of electrodes, whereby the membrane containing material is treated with the added treating substance and with electrical fields of sequentially varying directions. The routing of applied pulses through the electrode selection apparatus (110) to selected electrodes (121-128) can be done in an enormous number of ways.
Patent CA-2266100-A1 (CA)
Inventor: CUYLEN MICHAEL
IPC: H04L29/08
Filed: 1997-09-08
Abstract: The invention concerns a method of transmitting data between a first transmission devie (U1) and a second transmission device (U2) over a transmission link (K), transmitted data blocks (Bx') being returned for test purposes and optionally repeatedly transmitted. Advantageously, this method enables data to be transmitted rapidly and in an error-free manner even when there is interference (X) in the transmission link (K). This method is particularly advantageous for transmission links (K) which cannot be screened against disturbing influences or can be screened only as a function of electromagnetic compatibility (EMC) measures.

Title: Structure and method for super fet mixer having logic-gate generated fet square-wave switching signal
Inventor: DEXTER CHARLES EDWARD
IPC: H03D9/06
Filed: 1999-01-29
Abstract: A mixer comprising a local oscillator input port for receiving an externally generated sinusoidal local oscillator signal at a local oscillator frequency. A phase splitter is coupled to said local oscillator input port for receiving said local oscillator signal and for generating first and second phase separated signals at said local oscillator frequency having a substantially 180 degree phase difference between each other. A voltage potential isolator generates first and second differential signal pairs at said local oscillator frequency respectively from said first and second phase split signals. A square wave signal generator generates first and second floating square waves respectively from said first and second differential signal pairs. Each square wave signal has a high slew rate leading and trailing signal edge such that one FET switches ON precisely when the other PET switches OFF. At least one frequency mixing device receives said first and second square wave signals and an input signal from an input port at an input frequency and generates an output signal at an output port at an output signal frequency. An input/output signal separator separates said output signal from said input signal and directs said output signal to an output port.

Title: Impaired brca2 function in cells and non-human transgenic animals
Inventor: HASTY PAUL
IPC: C12N15/85
Filed: 1998-08-25
Abstract: ScRad51, a member of the RAD52 epistasis group in Saccharomyces cerevisiae, is a major component in the recombinational repair pathway employed to repair genetic damage caused by ionizing radiation. The mouse homologue of ScRad51, MmRad51, appears to have a similar function; however, the precise mechanism of action is not well understood. For ScRad51, protein:protein associations are critical for function. Therefore, the yeast two-hybrid system was used to isolate proteins that associate with MmRad51 to better understand recombinational repair in mammalian cells and mouse Brca2 was isolated. In humans, BRCA2, is a tumor suppressor gene important in the etiology of breast cancer. A phenotypic comparison between MmRad51 and Brca2-deficient embryos and cells suggest the protein:protein association is important for their function. Similar to MmRad51, Brca2 function is critical for repair of .gamma.-radiation induced damage. In addition, a subtle mutation that removes only the small portion of Brca2 that associates with MmRad51, either directly or indirectly, exhibited a phenotype that suggests partial function. These homozygous mutant cells are viable yet hypersensitive to ionizing radiation and undergo premature replicative senescence. Cells and mice were generated with impaired Brca2 function that should prove useful as a model for tumorigenesis, a model to analyze genotoxic agents and as a tool to study premature replicative senescence.
