Abstract:
An equine inverted posture alarm (EIPA) system to alert personnel of a pregnant equine specimen experiencing symptom of an abnormal or difficult parturition, or an equine specimen experiencing painful colic symptoms as demonstrated in both situations by the equine specimen exhibiting violent thrashing and posture inversion, through the utilization of components comprising:a) a sensor housing; b) a radio frequency transmitter; c) a posture position sensing gravitationally referenced switch comprising a longitudinal electronically insulated capsule, wherein the switch capsule assumes a normally closed detect enable state for 180 degrees in the rotary plane, and the longitudinal axis of the capsule is perpendicular to the earth's horizon when mounted within the sensor housing and installed on the harness of the equine specimen assuming a normal standing position; d) a harness apparatus which is fitted around the girth of the equine specimen; e) a radio frequency receiver; f) an alarm detection monitor which responds to a signal from the radio frequency transmitter based on the change of gravity as sensed by the posture position sensing gravitationally referenced switch, wherein said alarm detection monitor includes a time delay circuit; g) a monitor housing.
