Remote shock sensing and notification system
First Claim
1. A low-power shock sensing system, comprising:
- at least one shock sensor physically coupled to a chemical storage tank to be monitored for impacts;
an RF transceiver, said RF transmitter being in a low-power idle state in the absence of a triggering signal; and
interface circuitry for generating said triggering signal when activated by said shock sensor, an output of said interface circuitry coupled to an input of said RF transmitter, wherein said interface circuitry triggers said RF transceiver with said triggering signal to transmit an alarm message to at least one remote location when said sensor senses a shock greater than a predetermined threshold, said remote location includes a wireless transceiver system;
wherein said shock sensor comprises a linear transducer and at least one comparator, wherein said comparator compares an analog output signal provided by said linear transducer to a predetermined threshold, and wherein an output of said comparator activates said RF transmitter only when an amplitude of said analog output signal is above said predetermined threshold.

Abstract
A low-power shock sensing system includes at least one shock sensor physically coupled to a chemical storage tank to be monitored for impacts, and an RF transmitter which is in a low-power idle state in the absence of a triggering signal. The system includes interference circuitry including or activated by the shock sensor, wherein an output of the interface circuitry is coupled to an input of the RF transmitter. The interface circuitry triggers the RF transmitting with the triggering signal to transmit an alarm message to at least one remote location when the sensor senses a shock greater than a predetermined threshold. In one embodiment the shock sensor is a shock switch which provides an open and a closed state, the open state being a low power idle state.
