A process is disclosed for enabling an operator to exercise on an exercise device. The process includes measuring a range of movement of the operator during exercising on the exercise device for generating an electronic range of movement data. A strength is measured of the operator during exercising on the exercise device for generating an electronic strength data. An electronic program is designed based on the electronic range of movement data and the electronic strength data. The electronic program is stored in an electronic media. The electronic program is displayed as a moving scale on a screen for instructing the operator to exercise at the same rate as the moving scale to complete the exercise in a timely and controlled matter.

Stackable container systems

An underground pipe and cable locator for continuous depth readings comprises a top and bottom receiver antenna sensor each connected to respective amplifier channels. A separate transmitter is used to stimulate electromagnetic radiations from a buried pipe, cable, or other electrical conductor. The bottom receiver antenna sensor is sampled and used to synchronize a phase locked loop controlled oscillator. The exceedingly faint and noise-riddled signals obtained from the top and bottom receiver antenna sensors are full-wave rectified without the use of rectifiers or diodes that can introduce distortions and offsets. Such signals are full-wave rectified by synchronously switching between inverted and non-inverted copies with an analog switch such that only the positive cycles of each are output in one pulse train. A continuous output is therefore obtainable from the top and bottom receiver antenna sensors, and this, in turn, permits a continuous display of the depth estimate of the buried conductor.

A method for locating the joints and fractures of underground cast iron gas mains comprises connecting several sections of an underground cast iron gas main pipeline across a sixty watt signal generator with an audio-frequency signal output of 7800 hertz. The connections take advantage of service lines, valve boxes and drip access at the surface, otherwise holes are drilled to accommodate contact probes. The signal passes through the pipe sections and their joints in series. The centerline of the underground cast iron gas main pipeline is plotted directly above on the surface of the ground, e.g., along a surface centerline. The relatively higher impedance of the pipe joints compared to the pipes themselves, causes current fluxes to radiate from each joint. The relative linear positions and their corresponding signal power measurements are collected along the surface centerline. The locations of the joints of the underground cast iron gas main pipeline are estimated to be directly below points on the surface centerline that provide signal power peaks.

Method for locating the joints and fracture points of underground

An apparatus and method for determining the location of a concealed conductive object. The method includes the steps of determining the lateral position of the object by using an antenna array to detect a signal propagating on the object. The antenna array is comprised of at least one center antenna positioned perpendicular to a surface concealing the object and at least two antennas symmetrically positioned about the center antenna at angles not equal to ninety degrees. The depth of the concealed object is determined by using a bottom sensor to detect the signal propagating on the object as a first signal. A vertically displaced top sensor then detects the signal as a second signal which is amplified by a variable gain amplifier until it equals the first signal. The depth of the object is calculated from the gain increase required to achieve equality between the first and second signals. The variable gain amplifier comprises a plurality of iteratively connected amplifiers whose gains are set by digital commands from an up/down counter. The gain increase is determined by a direct current, digital-to-analog converter amplifier which receives the same digital commands as the variable gain amplifier. The lateral direction to the object is determined by comparing the phase of the signal generated by the antenna array to a reference phase.
