Hose separation transmitter system and methods
First Claim
1. A system for determining whether a delivery hose has disconnected or separated from a source of fluid and for automatically terminating the flow of fluid in response to determining that the delivery hose has disconnected or separated, said system comprising:
- a transmitter;
a shock sensor for providing a shock signal when a disconnected or separated hose strikes the ground or comes into contact with any object, said transmitter responsive to the shock signal from the shock sensor to transmit a disconnect signal;
means for securing the transmitter and shock sensor to said delivery hose;
a receiver for receiving the disconnect signal from the transmitter and for determining that a disconnect signal has been transmitted by the transmitter; and
means for terminating the flow of fluid from the source of fluid in response to the receiver determining that a disconnect signal has been transmitted by the transmitter.

Abstract
A hose separation transmitter system includes a shock sensor and a transmitter that are secured to the delivery hose. If the hose becomes disconnected, the shock sensor will generate a shock signal when the hose falls to the ground and the transmitter will respond to the shock signal by generating an encoded RF signal. A receiver at the vehicle receives the RF signal from the transmitter, determines that a hose disconnect has occurred, and automatically disables a fluid pump or closes a valve to stop the flow of fluid. The shock sensor preferably uses a strip of piezoelectric material. Related methods are also disclosed. For quick connect and disconnect, the shock sensor and transmitter are preferably secured to the hose by a hook and loop fabric material. The transmitter is immune to normal ambient vibration levels. Related methods are also disclosed.

1. A system for determining whether a delivery hose has disconnected or separated from a source of fluid and for automatically terminating the flow of fluid in response to determining that the delivery hose has disconnected or separated, said system comprising:
-
a transmitter; a shock sensor for providing a shock signal when a disconnected or separated hose strikes the ground or comes into contact with any object, said transmitter responsive to the shock signal from the shock sensor to transmit a disconnect signal; means for securing the transmitter and shock sensor to said delivery hose; a receiver for receiving the disconnect signal from the transmitter and for determining that a disconnect signal has been transmitted by the transmitter; and means for terminating the flow of fluid from the source of fluid in response to the receiver determining that a disconnect signal has been transmitted by the transmitter. - View Dependent Claims (2, 3, 4, 5, 6, 7)

13. A method for determining that a delivery hose has disconnected or separated from a source of fluid said method comprising the steps of:
-
securing a shock sensor and transmitter to said delivery hose; generating a shock signal in the shock sensor when the delivery hose falls to the ground or comes into contact with any object; and transmitting a disconnect signal from a transmitter to a receiver when the shock sensor generates the shock signal. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
