| 7124655 | Two-wire sensor for measuring a physical parameter To measure a physical parameter, a two-wire sensor produces pulse-width modulated signals (PWM) whose pulse width is preferably modulated as a function of the physical parameter to be measured. To indicate an error or a malfunction, the two-wire sensor provides an e... | 10/24/2006 |
| 4539471 | Hydraulic counting cell A hydraulic recalculating cell has a substantially vertical inlet portion, an inclined portion connected by its lower end with a lower end of the inlet portion, a further substantially vertical portion connected by its upper end with an upper end of the i... | 09/03/1985 |
| 4224964 | Binary fluidic counter A binary fluidic counter which produces two outputs, each having a frequency one-half the frequency of the supply. The counter incorporates a pair of bi-stable fluidic amplifiers, the first receiving a pulsed fluid supply while the second receives a conti... | 09/30/1980 |
| 4150561 | Employing a fluidic oscillator, for determining the constituent gases of a gas mixture In order to determine the constituent gases of a gas mixture, the test gas is employed as the working fluid for an astable fluidic oscillator in a series of runs taken at different temperatures. The pulse repetition frequencies observed are related to sim... | 04/24/1979 |
