Patent CA-2296365-A1 (CA)
Inventor: WILDE HORST
IPC: E05F15/00
Filed: 1998-08-12
Abstract: A force-responsive sensor comprises upper and lower cover layers (10, 12), the upper layer being resilient and flexible and shown as transparent for ease of illustration. An electrically conductive layer (14) carries separate individual electrically insulating spacers (16) which separate it from two electrically conductive members (18, 20). Each of these members (18, 20) has a plurality of spaced resilient fingers (24, 28), the fingers of the two members (18, 20) being inter-digitated. The members are formed as films on the layer (10). Where the members (18, 20) are not supported by the spacers (16), they are normally held apart from the conductive layer (14) by the resilience of the upper layer (10). In response to an applied force (F), one or more of the fingers (24, 28) is pressed into contact with the conductive layer (14) to enable the production of a corresponding electrical signal. The positioning of the spacers (16) ensures that they do not increase the overall width (w) of the sensor. The sensor may be used in a safety system for detecting obstructions in a window opening having a motor-slidable window glass.

Title: A modular time-space switch
Inventor: LINDBERG MIKAEL
IPC: H04Q11/04
Filed: 1998-08-10
Abstract: The present invention relates to a switch structure for circuit switching. According to the invention, part of the space switch functionality of a time-space (TS) switch core is broken out and arranged in groups of switch adapter boards, and the TS-switch core itself is divided into a matrix of smaller and independent TS-modules that are associated with the switch adapter boards. Each group of switch adapter boards is co-operating with a predetermined row of TS-modules in the matrix for input of data to the TS-modules in that row, and with a predetermined column of TS-modules in the matrix for output of data from the TS-modules of that column. In this way, it is possible to implement the switch structure into a number of subracks with a reasonable number of interconnections between different subracks, thus obtaining a truly modular TS-switch structure.

Title: De-ice and anti-ice system and method for aircraft surfaces
Inventor: RUTHERFORD ROBERT B
IPC: B64D15/12
Filed: 1998-09-18
Abstract: A thermal de-ice and anti-ice system for aircraft surfaces employs a laminate in which flexible expanded graphite foil (20) is an electrical and heat conducting layer (22) that is disposed below an outer heat conducting layer (24), with an electrically insulating layer below the graphite layer. The flexible expanded graphite layer requires about three times less wattage than known resistance heating pad thermal systems to achieve de-ice and/or anti-ice temperatures. The temperature of the surface is controlled by varying the power supplied to the flexible expanded graphite layer of the laminate in response to a real time temperature value transmitted to a power control.
Patent CA-2302201-A1 (CA)
Inventor: LACROIX JEAN-MICHEL
IPC: C12Q1/68
Filed: 1998-09-28
Abstract: A streamlined, hierarchical method for obtaining information about the allelic type of a sample of genetic material derived from an HIV-infected sample relies on the observation that 93-95 % of the known mutational variants of the reverse transcriptase and protease genes of HIV-1 can be determined by evaluating the positions of the A and T nucleotides within the sample. Thus, a substantial fraction of all mutational variations can be unequivocally identified by performing two initial sequencing reactions on the sample in which only ddA and ddT are used as chain terminators. For the small fraction of samples which are not identifiable based on the positions of these two bases, a second test is performed in which the sequence is determined in the 3'-direction for all four bases. This test will identify substantially all of the remaining samples. For those for which an ambiguity remains, however, a final test in which the sequence of the sample is determined in both the 3' and 5-direction for all four bases in performed. To perform the method, reagents suitable for performing the three tests within the hierarchy are suitably packaged as a kit containing two or more sub-kits. The first sub-kit contains reagents for performing A and T sequencing. The additional sub-kits contain reagents for performing a four-base sequence determination on one or both strands of the target DNA.

Title: Burner with piloting ports
Inventor: JENNINGS RALPH ERNEST
IPC: F23D14/04
Filed: 2000-03-23
Abstract: A cooking appliance includes burners having ports that are aligned in a defined alignment with respect to an adjacent structure of a burner body or the cooking appliance within a piloting zone so that the adjacent structure guides the formation of a flame kernel at an outlet of the port. The adjacent structure may be ports which also form flame kernels withing the piloting zone of the burner port outlet, a structural portion of the burner body such as an extended lip protruding beyond the burner port or a separate structure such as a flame rod or other target that stabilizes the flame kernels at the burner port outlet. Such structures provide a method for improving the turndown ratio of burners by preventing lifting or backlash of the flame kernels generated at the burner port outlets by aligning the ports in conjunction with an adjacent structure within a piloting zone.

Title: Audio signature extraction and correlation
Inventor: LU DAOZHENG
IPC: G10L19/00
Filed: 2000-06-06
Abstract: A signature is extracted from the audio of a program received by a tunable receiver such that the signature characterizes the program. In order to extract the signature, blocks of the audio are converted to corresponding spectral moments. At least one of the spectral moments is then converted to the signature. Also, a test audio signal from a receiver is correlated to a reference audio signal by converting the test audio signal and the reference audio signal to corresponding test and reference spectra, determining test slopes corresponding to coefficients of the test spectrum and reference slopes corresponding to coefficients of the reference spectrum, and comparing the test slopes to the reference slopes in order to determine a match between the test audio signal and the reference audio signal.
