Patent DE-4212507-A1 (DE)
Title: Non-invasive detector of variations in blood vol. or pressure - uses microprocessor and electronic pump controller for computation and display of incremental volume of exercised limb
Inventor: BLAZEK VLADIMIR DR ING
IPC: A61B5/0215
Filed: 1992-04-14
Abstract: Air is pumped (8) through a valve (7) and pneumatic coupler (4) into a cuff at a basic pressure of 10 to 20 torr. An electronic controller (10) instigates additional pumping during one or more short intervals while the consequent increase in pressure is measured by a sensor (S) calibrated in millilitres from knowledge of the pump vol. and air compressibility and temp. The controller calculates the enclosed tissue vol. at rest so that the measured changes in vol. can be expressed also in percentage terms when the limb (E) is exercised. USE/ADVANTAGE - Variations in vol. of extremities or of pressure in a subcutaneous vessel during exercise can be evaluated in both relative and absolute units.

Title: Evaluating method and circuit for an inductive sensor
Inventor: EDEN GERD DIPL ING
IPC: G01D5/20
Filed: 1993-04-23
Abstract: A method for evaluating an inductive sensor (1, 9), particularly a displacement sensor (1), is proposed, the set displacement (s) being determined from the measured inductance (L) of the sensor by means of a microcontroller (15). In this process, the temperature-dependent copper resistance (Ri) of the winding (2) of the displacement sensor (1) is determined by means of a measuring current which is constant in time. The microcontroller (15) is then used for temperature-compensating for the displacement (s) determined from the inductance (L) with the aid of a value corresponding to the copper resistance (Ri). The method can be used, in particular, in the case of displacement sensors which are employed in locations with highly fluctuating temperatures. <IMAGE>
