摘要： A river ice motion detector system for detecting ice run conditions in or to warn communities downstream that flooding from ice jams is possible, comprises a voltage source, a multi-meter, a detector unit and a plurality of sensor loops, all having communication with each other. The voltage source provides an input signal to the detector unit and then to the sensor loops. The sensor loops provides a second signal back to the multi-meter in response to the input signal. The detector unit has a plurality of resistors and a plurality of switches, the values of the resistors determined providing large step differences, allowing the detector unit to determine which of the sensor loops is broken indicating a possible ice run. The switches are normally closed, providing a test for the system when the switches are deliberately opened.

摘要： A data acquisition apparatus that includes a recorder device of an event's ime and date signified by the opening of an external trigger switching circuit in combination with a complimentary interrogator device for collecting data from the recorder device. The recorder device's components comprise a battery powered source with a power regulator, a processor, a dip-switch identifier, a programmable read only memory, a clock/ calender with random access memory, a timing/control subcircuit interface that connects to the external trigger switching circuit(s) and an output interface port for data transmissions with the interrogator device. The recorder's timing/control subcircuit interface extends battery life by sensing and transmitting electrical pulses through each external trigger switching circuit. The interrogator device is portable and has multiple functional capabilities. This interrogator comprise an regulated battery power source, a processor, a programmable ROM, an event storage RAM, a clock/calender subcircuit, an optional liquid crystal display display, and an input/output interface port to communicate with the recorder device.
