Microwave oscillator position sensor |
摘要 |
A microwave oscillator circuit having an antenna, wherein the effective reactive impedance of the oscillator circuit is altered by the movement of a reactive impedance changing element past the antenna to cause change of the oscillation condition of the oscillator. A change in oscillation condition is sensed and sent to a utilization device to determine speed and/or position. The utilization device can be a computer which receives a signal from a wheel speed determining system, wherefrom a signal is sent back to a braking system for the wheel to control braking thereof. This can be accomplished individually for each of the four wheels to provide an anti-locking braking system.
