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 interface 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 transmitter 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.

14. A low-power shock sensing system, comprising:
-
at least one shock sensor physically coupled to a chemical storage tank to be monitored for impacts, wherein the shock sensor comprises at least one mechanically activated sensor coupled to at least one mechanical shock switch having an open and a closed state, the closed state being mechanically initiated by the mechanically activated sensor in response to the mechanically activated sensor receiving a shock greater than a predetermined threshold; an RF transmitter, the RF transmitter being in a low-power idle state in the absence of a triggering signal; and interface circuitry for generating the triggering signal, the interface circuitry activated by the shock switch being in the closed state, wherein an output of the interface circuitry is coupled to an input of the RF transmitter, and wherein the interface circuitry triggers the RF transmitter with the triggering signal to transmit an alarm message to at least one remote location. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A computer-readable storage medium of a computing device, the storage medium comprising computer instructions for causing the computing device to perform the steps of:
-
receiving a shock signal from a linear transducer physically coupled to a chemical storage tank to be monitored for impacts; determining whether the shock signal indicates a shock greater than a predetermined threshold using a comparator that compares an amplitude of an analog output signal of the linear transducer to the predetermined threshold; and transmitting a triggering signal to an RF transmitter when the shock is greater than the predetermined threshold, the triggering signal being adapted to cause the RF transmitter to transmit an alarm message to at least one remote location, the RF transmitter being in a low-power idle state in the absence of the triggering signal. - View Dependent Claims (30, 31)

32. A method of monitoring for shock associated with a storage tank, the method comprising:
-
receiving a first shock signal from a linear transducer physically coupled to the storage tank to be monitored for impacts; determining whether the first shock signal indicates a shock greater than a predetermined threshold; determining whether a mechanical shock switch is in a closed state, the mechanical shock switch being connected to a shock sensor physically coupled to the storage tank to be monitored for impacts, the shock sensor comprising a mechanically activated sensor coupled to the mechanical shock switch which has an open state and the closed state, the closed state being mechanically initiated by the mechanically activated sensor in response to the mechanically activated sensor receiving the shock greater than the predetermined threshold; and transmitting a triggering signal to an RF transmitter when the first shock signal is determined to indicate the shock being greater than the predetermined threshold or when the shock switch is in a closed state, the triggering signal being adapted to cause the RF transmitter to transmit an alarm message to at least one remote location. - View Dependent Claims (33)
