Patent CA-1335043-C (CA)
Inventor: GRAY TOMMY L
IPC: G01F15/06
Filed: 1988-01-19
Granted: 1995-04-04
Abstract: In the measurement of fluid flow, the generation of a linearly varying signal and a pulsation free display are provided by a flow responsive indicator having digit displays for numerically indicating the rate of measured flow. The digit displays are driven in accordance with a measured flow signal applied to circuitry for generating an updated display signal from a previous display signal and the current value of the measured flow signal. This analog updated display signal is converted into a digital signal for driving circuitry connected to each of the digit displays. The measured flow signal applied to the indicator is generated at a flow transmitter including a transducer, such as a Hall effect element. This transducer generates a signal varying with flow in response to movement of a vane mounted in proximity thereto. To provide a signal varying linearly with flow rate, a flexible element extends into the fluid stream and byaction thereof displaces the vane with reference to the transducer to generate the desired linearly varying signal.

Abstract: SYSTEM FOR DETECTING IRREGULAR OPERATION   OF SWITCH STATE VERIFICATION CIRCUIT            ABSTRACT       A system for debouncing a switch circuit includes a sample circuit for providing an initial determination of the switch status,  and a debounce circuit connected to operate on the output of the sample or sensing circuit to verify the actual switch status by providing a confirmation signal.   The system of the invention accumulates a count related either to the rate at which the sample circuit operates,  or the actual changes in state indicated by latches coupled to the sample circuit.   If the count accumulates to a predetermined number before being cleared by a confirmation signal verifying the switch status, then the irregular operation is signalled.   This identifies a continuous,  rapid alternation between different switch states without a confirmation of an actual state change, which would otherwise be undetected by system operation.
