Abstract: An animal confinement system including at least one transmitter, a loop antenna associated with each transmitter, a loop monitor associated with each loop antenna, a remote communication device and a communication device. The transmitter sends a signal to the loop antenna. The loop monitor senses at least one attribute of the signal. The communication device is communicatively connected with the loop monitor. The communication device communicates at least one attribute to the remote communication device.

Abstract: A controller for use with a computer terminal sequentially actuates a plurality of relays each coupled in a respective AC line wherein each of the AC lines is coupled to and energizes one of a plurality of computer terminal peripherals. The sequence in which the various peripherals are powered up is determined by the relative sensitivity of each peripheral to line voltage and switching transients, with the most sensitive peripherals energized last and the least sensitive peripherals energized first. A sufficient interval is provided between each sequential peripheral power up to allow for the settling out of switching transients. Upon computer terminal power down, the controller sequentially removes power from each of the peripherals in a reverse order with power first removed from those peripheral devices most sensitive to the aforementioned line voltage and switching transients. A time delay is also incorporated in the power down sequence to allow for the settling out of switching transients.
