摘要:
A control device and method controls an animal's location. A GPS receiver and a processor determine the position, velocity and heading direction of the animal relative to a target. A stimulus unit selectively applies a stimulus to the animal. If the position of the animal relative to the target is less than a predetermined distance and the animal's velocity relative to the target is within a predetermined range and the heading direction of the animal is within a predetermined orientation relative to the target, then a non-aversive stimulus is applied to the animal, and removal of a non-aversive stimulus is selectively effected when the animal's velocity relative to the target is outside of the predetermined range, or the heading direction of the animal changes by more than a predetermined amount, otherwise the non-aversive stimulus is first removed followed by application of an aversive stimulus to the animal.
摘要:
A gas measurement device for measuring at least one gas in the stomach of a mammal, the device comprises a housing for being located in the mammal's stomach and providing at least one gas sensor for detecting the gas. The housing is impermeable to liquid within the stomach. The device may also comprise a controller disposed within the housing and which is electrically coupled to the at least one gas sensor. The controller is arranged to periodically process an output from the gas sensor(s) to provide data indicative of the amount of the gas within the stomach. The controller can include a wireless transmitter for transmitting the data to a remotely located receiving device disposed exterior to the mammal.
摘要:
A control device and method is taught for controlling an animal's location. A GPS receiver receives GPS signals and a processor determines the position, velocity and heading direction of the animal relative to a target. A stimulus unit selectively applies a stimulus to the animal in response to received signals. A processor is programmed such that if the position of the animal relative to the target is less than a predetermined distance and the animal's velocity relative to the target is within a predetermined range and the heading direction of the animal is within a predetermined orientation relative to the target, then a signal indicative of applying a non-aversive stimulus to the animal is generated, and a signal indicative of removal of a non-aversive stimulus is selectively generated when the animal's velocity relative to the target is outside of the predetermined range, or the heading direction of the animal changes by more than a predetermined amount, otherwise a signal is generated indicative of first removing the non-aversive stimulus followed by application of an aversive stimulus to the animal.
