Patent CA-2427425-A1 (CA)
Title: Method and arrangement for providing optimal bit protection against transmission errors
Inventor: MIKKOLA HANNU J
IPC: H03M13/27
Filed: 2001-10-30
Abstract: A method and arrangements are provided for transmitting frames of digital information over a wireless communication connection between a transmitter and a receiver. In the transmitter, a certain sequence of bits within each frame of digital information is convolutionally encoded and punctured (112) before transmitting the frame over a wireless communication connection. The receiver decodes and depunctures (211) the sequence of bits within each frame of digital information, that was convolutionally encoded and punctured, after receiving the frame over a wireless communication connection. The transmitter rearranges (411) the sequence of bits within each frame of digital information that is to be convolutionally encoded and punctured, before convolutionally encoding and puncturing (112) it. The rearranged order is one that has been found to produce, during the course of convolutionally encoding with a certain convolutional code and puncturing with a certain puncturing pattern, a convolutionally encoded and punctured sequence where the statistical probability of transmission errors exhibits a predefined behaviour (701). In the receiver, the sequence of bits within each frame of digital information that was so rearranged in the transmitter is inversely rearranged (611) so that the effect of said rearranging in the transmitter on the mutual order of the bits of the sequence is cancelled, after decoding and depuncturing the sequence of bits.

Inventor: BESSANT CONRAD
IPC: A61B5/08
Filed: 2002-04-19
Abstract: A state, particularly a disease state, associated with the production of volatiles is detected by passing a sample containing the volatiles to a single sensor. This may be a semiconductor gas sensor element or a surface acoustic wave device. This provides an output signal, e.g. in the form of a tailing peak. A plurality of characteristics of the signal (e.g. peak height and maximum positive gradient) are measured to characterise the sample and hence the underlying state. For example we can discriminate between urine samples which are (a) infected with proteus, (b) infected with E. coli or (c) uninfected.

Title: A novel electrode for use with atmospheric pressure plasma emitter apparatus and method for using the same
Inventor: TROPPER SETH
IPC: H05H1/24
Filed: 2002-07-01
Abstract: A plasma emitter apparatus and method for using the same that includes a primary electrode and a secondary electrode. The secondary electrode is porous, that is, it is configured to permit the passage of plasma discharge therethrough. Accordingly, the plasma is received at one side of the seconda ry electrode and emitted from its opposing plasma exiting side. Numerous configurations of the secondary electrode are possible so long as the plasma discharge is permitted to pass therethrough. For instance, the secondary electrode may be a laminate of multiple insulating material layers with at least one conductive layer sandwiched therebetween. A plurality of apertures are defined through the laminate and a dielectric sleeve is inserted into an d retained in the aperture. The generated plasma passes through one or more holes defined in each of the dielectric sleeves. Alternatively, the secondar y electrode may be formed as a plurality of unidirectional high voltage wires strung substantially parallel across a frame or a plurality of bidirectional high voltage wires interwoven and secured by a perimeter frame. Since the plasma passes through the secondary electrode the plasma reactor device may be in a position proximate or in direct contact with the surface of the object to be treated.

Title: Belt tensioner with installation pin
Inventor: COSMA RARES
IPC: F16H7/02
Filed: 2002-07-31
Abstract: A belt tensioner for tensioning the belt of a belt drive system includes an eccentric adjusting member, a pivot structure eccentrically mounted on the adjusting member for pivoting around the adjusting member, a belt-tensioning pulley mounted to rotate on the pivot structure, a biasing member that resiliently biases the pivot structure in a belt-tightening direction, and a coupling structure.
