Abstract: An exercise equipment configured to exercise muscles by require the muscles to generate torque intermittently is provided. The exercise equipment includes a sleeve. A pipe is slidably disposed within the sleeve. The sleeve is concentric to the pipe wherein the outer surface of the pipe is spaced apart the inner surface of the sleeve. A counterweight is mounted to at least one end of the pipe wherein the rotation of the pipe along an orbital path causes the pipe to turn within the bore of the sleeve. The turning of the pipe is a result of the counterweights completing a revolution as the counterweights rotate about the longitudinal axis of the pipe. The turning of the pipe generates a pulse so as to actuate muscular structure within the body of the user.

Abstract: Several systems and methods for monitoring the proximity of a device to a power line are disclosed. Electric field monitoring systems are mounted to the device and include a plurality of electric field sensors and a monitoring system base unit. Each electric field monitoring sensor senses the strength of a magnetic field in which the sensor is positioned and transmits a corresponding magnitude output signal to the base unit when polled by the base unit. If a sensor reports a magnetic field exceeding a threshold, the frequency of polling for that sensor may be increased. If a sensor reports a magnetic field exceeding another (possibly identical) threshold, an alarm may be activated, movement of the device may be limited or stopped or another action or a combination of actions may be taken.

Abstract: A clutch arm centering device is disclosed. The device is mounted on a clutch using to operate piston valves on a crane or other heavy machine. The piston valves may be operated using a valve arm which has two operative positions and a neutral position between the two operative positions. A clutch arm of the clutch is linked to valve arm to allow the valve arm to be manipulated by a remote control coupled to the clutch. As parts of the linkage between the clutch arm and the valve arm wear, the centering device biases the clutch arm to a central position which corresponds to the neutral position of the valve arm, thereby avoiding problems of understroking and overstroking which arise in the prior art.
