Abstract: The present invention discloses a method and apparatus for electronically deterring an animal from approaching an exclusion area around an exclusion unit or from entering or leaving an area bounded by a wire. The animal is provided with a collar unit, which includes a sensor adapted to sense the strength of electromagnetic signals generated by the exclusion unit or wire and a correction unit adapted to provide correction to the animal in response to a sensor output. The portable unit reports to a central controller which selects a correction strategy, such as level of correction to be applied to the animal approaching the perimeter. The controller provides warnings to the user, including warnings for when the battery in the collar unit goes low and when the animal stays in a correction zone for too long. The controller may control a number of exclusion units and/or power units, and may select an appropriate correction for one of a plurality of animals.

Abstract: The invention provides an apparatus and method of monitoring a CVD process and providing an alarm signal normally used to terminate the CVD process in response to detecting the simultaneous occurrences of a command to initiate the CVD process, the initiation of the flow of a reactive process gas into the process chamber and the motion of a turret supporting the workpiece.
