IPC: G06K9/00
Filed: 1996-11-18
Abstract: An apparatus for detecting topographic variations on an object such as a finger includes an array of sensing elements disposed on a substrate which each have a parasitic capacitance. An insulating receiving surface is disposed over the array of sensing elements and is adapted to receive the object such that a sensing element and a portion of the object located thereabove creates a measurable change in capacitance with respect to the parasitic capacitance. An electronic circuit is coupled to the array of sensing elements for measuring the measurable change in capacitance.
Patent CA-2194064-A1 (CA)
Inventor: CAI XIONG
IPC: C07D471/04
Filed: 1995-06-27
Abstract: Tetrahydrofurans, tetrahydrothiophenes, pyrrolidines and cyclopentanes are disclosed that reduce the chemotaxis and respiratory burst leading to the formation of damaging oxygen radicals of polymorphonuclear leukocytes during an inflammatory or immune response. The compounds exhibit this biological activity by acting as PAF receptor antagonists, by inhibiting the enzyme 5-lipoxygenase, or by exhibiting dual activity, i.e., by acting as both a PAF receptor antagonist and inhibitor of 5-lipoxygenase. It has been determined that 5-lipoxygenase activity, oral availability, and stability in vivo (for example, glucuronidation rate) can vary significantly among the optical isomers of the disclosed compounds.

Patent CA-2206365-A1 (CA)
Title: Mobile communication system
Inventor: SATO TOSHIFUMI
IPC: H04J13/00
Filed: 1997-05-28
Abstract: A mobile communication system is arranged to have a code divisional multi access system as in the North American standard system and to control a transmission power for reducing an influence of interference of one channel to the others by lowering a control error of the electric power transmitted on an up line. In the base station, a receiving section of a transceiving unit provides a pilot symbol in-phase adding circuit for detecting a carrier signal point represented by an in-phase component and a quadrature component at regular intervals. The amplitude of the detected carrier signal point is corrected by an amplitude correcting circuit by using the previous control values for transmission power read from a memory. Then, a predicting circuit predicts a carrier signal point at a time when the next control for transmission power is executed by using the corrected carrier- signal point. The predicted carrier signal point is compared with a reference signal through a comparing circuit. Next, a transmission power control circuit generates a control value for transmission power at a time when the next control for transmission power is executed, transmits the control value to the mobile devices, and store the control value in the memory. The mobile devices control the transmission power based on the control value.

Title: Process for disinfecting aqueous solutions
Inventor: DEL GROSSO BIRGIT
IPC: C02F1/72
Filed: 1996-08-07
Abstract: Owing to the concomitant storage, transport, material and handling problems and the unsatisfactory retarding of reinfection, the use of commercially available peracetic acid solutions with a high peracetic acid (PES) an acetic acid content for disinfecting large quantities of aqueous solutions, e.g. purification plant outlets, has been closely limited. According to the invention, it is possible to disinfect even large quantities of aqueous solutions economically and at the same time retard reinfection by using a peracetic acid solution containing 1.5 to 2.5 wt.%  peracetic acid and 40 to 60 wt.% hydrogen peroxide and under 2 wt.% acetic acid as a disinfectant. Preference is given to the use of a peracetic acid solution with less than 1 wt.$  acetic acid.

Patent CA-2242187-A1 (CA)
Title: Method and device for recognizing tones and sequences thereof
Inventor: VERREAULT ERIC
IPC: H04N1/327
Filed: 1998-07-03
Abstract: A method for recognizing tones in a signal in a telecommunication transmission uses samples of the signal to determine whether a tone of an expected frequency and wave shape is contained in the signal. If the method accurately predicts the value of the next sample, then a tone of the expected frequency and wave shape has been detected. Another method may be used to recognize sequences of tones comprising intervals with particular frequencies and durations. The method may be applied to the detection of initiation sequences for fax and modem transmissions, for example the ITU-T recommendation T.30 V.21 fax initiation sequence and the ITU-T recommendation V.25 modem transmission preamble. The method may be incorporated in a device for detecting modem or fax transmissions on a line and routing such modem and fax transmissions to a modem/fax relay. Thus the invention can be used with devices which provide voice compression by ensuring that fax and modem transmissions are not corrupted by being passed through the voice compressors.
