Claim Text:
1. An apparatus for monitoring a parameter corresponding to a moving component, said apparatus comprising: a transmitter having a trigger input, a supply voltage input, a ground, and an output, said transmitter configured to provide a wireless signal based on said trigger input; an inductor connected between said trigger input and said ground of said transmitter, said inductor responsive to a magnetic field moving relative to said inductor; and a delay circuit connected between said ground and said supply voltage input of said transmitter, said delay circuit adding a delay to a signal applied to said supply voltage input whereby said supply voltage input reaches a minimum required operating voltage level after said trigger input reaches a minimum required trigger voltage level, wherein when said magnetic field interacts with said inductor, said inductor generates power for said transmitter and triggers said transmitter.
