Abstract: Electrical fence lines provide an electromagnetic barrier to deter crossing. This barrier becomes compromised by lack of power, grounding of the powered lines, and/or loss of upright structure. Although some monitoring systems use audio and visual alerts (ie horns and blinking lights), they require immediate observation for immediate attention. Radio wave alerts are limited in range and receivers. Cellular phone networks are sometimes used with telecommunication monitoring systems but require specific carriers to communicate to certain cellular devices based on the technology (ie GSM, CDMA) used by the carrier. With the Smart Stake, the Internet and any communications server can be used to send alerts to any cellular device, email address, or networked device on the conditions of the electric fence.

Abstract: An exercise device of the push-pull type is disclosed. The device consists of a pair of parallel channels, knee rest unit, and hand grip unit. Either the hand grip unit and the knee rest unit can slide freely along the length of the channels, while the other unit is held stationary. Both the knee rest unit and hand grip unit have user-variable resistance means. The invention may be disassembled and folded for easy storage and transportation.
