Patent CA-2285156-A1 (CA)
Title: A constant current termination for cable locating tones
Inventor: VOKEY DAVID E
IPC: G01R31/08
Filed: 1999-10-06
Abstract: A constant current termination is provided for cable locating tones on communication and control cables that may be buried or placed in underground duct structures. The constant current termination limits the current on each branch of the cable to that required for cable location, thus ensuring that branches furthest from the tone source have adequate current for location purposes. The termination is the same for each branch, regardless of its position along the cable system. This eliminates the need to calibrate and recalibrate termination distances for a cable on installation and when branches are added. It also allows the location of damaged cables where the tone signal strength on a damaged brat is less than that for which the termination was designed.

Title: Method and apparatus for electro-coagulation printing and electrode control unit
Inventor: MUROI KUNIMASA
IPC: B41C1/10
Filed: 2000-07-12
Abstract: An electro-coagulation printer uses an electrode control unit to drive electrodes (22) which are aligned in proximity to a rotation drum (24) having a conductive ink film on its surface. The electrodes are respectively electrified to partially coagulate the conductive ink film to form ink dots on the surface of the rotation drum, so that the ink dots are transferred onto a paper. Herein, the electrode control unit receives print data (3) from a host device (2) by way of an interface (4). Gradation data representing gradation values for one line of the electrodes are created based on the print data and are output in a serial manner. The serial gradation data are converted to parallel data corresponding to the gradation values, which are held and controlled in output timing. That is, output timings of the gradation values are independently controlled based on correction information such that print positions of the ink dots are corrected in at least one of a paper-feed direction and an alignment direction of the electrodes.      Based on the gradation values, pulse signals are generated to drive the electrodes respectively. Herein, each of the pulse signals consists of a number of pulses designated by the gradation value, or each of them consists of a single pulse whose pulse width depends on the gradation value. It is possible to differ the pulse signals from each other in phases. Thus, it is possible to print desired images on papers with a high quality and at a high speed.

Title: Air pressure indicator for a vehicle tyre
Inventor: TSAGAS FOTIOS
IPC: B60C23/04
Filed: 1999-10-12
Abstract: The present invention relates to a device which indicates the safety limits of the air pressure in each one of the pneumatic tyres of a vehicle by transmitting appropriate information from the wheels to the driving control board. Transmission of information is based on the capacitive coupling between rotating and non-rotating conductive annular surfaces (2-5, 12-19, 72-75) which are mounted into channels of insulated bases (6-9) fixed in the available space between the bearing flange, the braking system and the wheel bearings (66) and are forming cylindrical and plane capacitors. An electronic circuit incorporates these capacitors as basic elements for its operation, and also an AC bridge (20) to give an automatic compensation by measuring the differential capacitance for each pair of the wheels to avoid faulty indication due to causes like humidity, temperature, etc. Also a simple electronic circuit can be used for each one of the wheels. A tyre pressure sensor (1) comprises a semiconductor membrane (30) with an electrode (33) which is shorting out the rotating conductive surfaces (2, 3, 12, 13, 16, 17, 72, 73) when the tyre pressure deviates from the safety limits resulting in a change of the original frequency and giving visual display or audio indication.
