Patent CA-2258263-A1 (CA)
Inventor: FLAHERTY BRYAN PATRICK
IPC: A61B5/022
Filed: 1997-06-12
Abstract: A blood pressure can be obtained by supplying an external pressure to a portion of an artery. The external pressure is preferably between the systolic and diastolic pressure. An event which occurs at least once a cycle can then be identified. This event can be, for example, a peak in the arterial compliance that occurs at a transmural pressure approximately equal to zero. A  pair of signals, one that is an arterial volume-indicating signal, and one that is an arterial pressure-indicating signal can be used to identify this event. Alternately, a small signal high-frequency exciter component can be placed upon the pressure or volume of the artery and detected to determine the time that the transmural pressure is equal to zero.

Patent CA-2277897-A1 (CA)
Title: System for controlling tension of a primary backing material in a tufting machine
Inventor: MCGOWAN OLIVER W
IPC: D05C15/14
Filed: 1998-01-15
Abstract: A system for controlling tension improves carpet quality by maintaining tension along a primary backing material at a constant value. The system controls the tension by maintaining the speed of an entry pin roller slightly slower than the speed of an exit pin roller. The exit pin roller is driven with a main drive motor while the entry pin roller is independently driven by a separate vector drive motor. Am encoder, coupled to the exit pin roller, is driven in synchronism with the exit pin roller and produces a pulsed output which is converted into an analog signal representative of the speed of the exit pin roller. A controller receives a user-defined desired value of tension and monitors outputs of a pair of load cells to determine the amount of tension actually on the primary backing material. Based on the difference between the actual value of tension and the desired value of tension, the controller produces a control signal which is fed to a drive circuit. The drive circuit drives the vector motor and, consequently, the entry pin roller at a speed dictated by the analog signal representing the speed of the exit pin roller and the control signal generated by the controller. The quality of the carpet produced by the tufting machine is improved since the stitch density and the carpet pattern remain substantially constant whereby variations in patterns can be minimized.

Title: Signal analog processing circuit for satellite positioning receiver
Inventor: RENARD ALAIN
IPC: H03D7/16
Filed: 1998-01-30
Abstract: The invention concerns satellite positioning receivers, more precisely the analog circuit receiving satellite signals from an antenna, comprising circuits for frequency translation and an analog-to-digital converter (CAN). For carrying out frequency translation, the circuit comprises at least two frequency dividers (DF1, DF2),of which the first is programmable for supplying at least the following division ratios: 140 and 143, and preferably one of the following ratios: 137, 140, 142, 143. The other divider is preferably for taking one of the following division ratios: 10 and 11. A third divider (DF3) can take the ratios 3, 5, 7, or 8. The invention is characterised in that as a result of this choice of division ratios a single analog integrated circuit topography allows a large number of possible applications, instead of producing one specific circuit for each application. The possible applications are civilian and/or military receivers, operating on the GPS constellation or on the GLONASS constellation, and this in spite of the predictable future developments concerning transmission frequency for the GLONASS constellation.
