Title: Signal transformation for an incremental sensor
Inventor: BUECHER JOHANN
IPC: G01D5/244
Filed: 1990-09-04
Abstract: A signal conversion for incremental sensors or the like is described, in which sensor signals of corresponding position or angular position are supplied with a particular input frequency via channels A, B to a phase discriminator which generates counting pulses which are supplied to further hardware counters for detecting the displacement or angle information. The basic object is here to increase the input frequency of the sensor channels without reducing the number of counting pulses and thus the accuracy and without exceeding the limit frequency of the hardware counters. This is achieved by the signal sequence of channel A and channel B, subdivided into periods, being additionally supplied to a decoder which precedes the hardware counter, the lowest 2 bits in question containing the absolute displacement or angle information.

Abstract: The device avoids the disadvantages of a limitation in current across the load circuit (RL) to which the voltage source (ST) is connected, so as to permit transient current draws, and alleviate energy dissipation when a short-circuit is present. The device comprises a detecting-measuring circuit (DM) of load voltage VL greater than thresholds VL1 and VL2 < VL1, a positive temperature coefficient thermistor (TH) with toggle voltage VL2 << VTHb @ VL1, an electronic switch (IE) in series with the thermistor (TH) and controlled by the detecting-measuring circuit (DM), and a shunt resistor (RD). The switch toggles from the closed normal state to the open state once VL > VL1 in response to a short-circuit, the source (ST) then being connected to the elevated shunt resistor (RD), and from the open state to the closed state once VL > VL2. <IMAGE>

Abstract: Arranged in the tonometer housing (1) is a forehead support (8, 9) which can be pushed in counter to the pressure of a spring (10) and which can be locked rigidly in a defined position in the housing by means of a locking tooth (13) engaging in a toothing (11). By means of a linear motor (5), a measurement element (2) can be advanced towards the eye (14) in order to measure the intraocular pressure in a conventional manner. The measurement result is stored and indicated on a display (15). By virtue of the stable bearing of the tonometer with the aid of the forehead support (8, 9) and a fully automatic control of the measurement procedure, the tonometer can be used for tonometry by the patient himself/herself, i.e. the test subject or patient can measure the actual intraocular pressure himself/herself without any external aid. The measurement can therefore be carried out, without appreciable expenditure, relatively frequently and at any desired times, which is of importance for a reliable diagnosis.

Suivant les variations de la capacité, le temps de retard entre l'impulsion première ou impulsion de prospection sous-marine et l'impulsion de cavitation est enregistré à chaque décharge en même temps qu'est calculée la fréquence dominante du spectre du signal de prospection. Les valeurs de capacité sont ensuite fixées de manière à fournir à la fois des impulsions de cavitation qui ne contribuent que pour un minimum à l'impulsion obtenue et un spectre de fréquence dominante aussi large que possible. Les valeurs de capacité prédéterminées sont attribuées à un réseau de condensateurs (C1-C10) dont chacun est relié à un transducteur paraboloïdal électroacoustique (P1-P10) immergé dans l'eau et dont les électrodes sont alimentées de manière à produire l'impulsion de prospection sous-marine.
