摘要： A variable reluctance sensor system for processing a variable reluctance sensor signal including an arming comparator and an arming circuit. The arming comparator compares the variable reluctance sensor signal with an arming threshold which decreases proportional to 1/t from a predetermined maximum level and asserts an armed signal when the variable reluctance sensor signal reaches the arming threshold. The arming threshold may be decreased based on a scaling factor multiplied by 1/t to ensure detection of each pulse of the variable reluctance sensor signal. The arming threshold may decrease to a predetermined minimum level sufficiently low to intersect the variable reluctance sensor signal and sufficiently high relative to an expected noise level. The arming threshold is reset in response to a timing event, such as zero crossing of the variable reluctance sensor signal.

摘要： An interface for processing a variable reluctance sensor signal provided by a variable reluctance sensor including an integrator, an arming comparator and a detect circuit. The integrator includes an input for receiving the variable reluctance sensor signal and an output providing an integrated signal indicative of total flux change of the variable reluctance sensor. The arming comparator compares the integrated signal with a predetermined arming threshold and provides an armed signal indicative thereof. The detect circuit provides a reset signal after the armed signal is provided to reset the integrator. A corresponding method of processing the variable reluctance sensor signal is also described.

One or more dielectric components are positioned within the gap directly between the first and second coils. During operation, a first signal is provided to the first coil, and the first coil converts the signal into a time-varying magnetic field. The magnetic field couples with the second coil, which produces a corresponding second signal.
