Abstract: A tire path, guidebeam, electric rail configuration for a guideway in a people mover system comprises a roadway structure having a pair of spaced tire paths forming a vehicle running surface. A guidebeam is disposed along a centerline between the tire paths to provide generally vertical guidance surfaces above the tire running surface for generally horizontal guidewheels on the vehicles. First and second electric rail units are substantially identically structure and extend along the roadway structure between the tire paths to provide conductive surfaces above the tire running surface for electric collection by brush assemblies on the vehicles. Together, the electric rail units have a predetermined number of electric rails to provide power and signal circuits for the vehicles. The first and second electric rail units are supported on opposite sides of the tire path centerline and at substantially equal distances from the centerline to enable turnaround vehicle operation.

Abstract: A test method for measuring the differential processing time of each side of a subject's auditory system and indicating brain dominance employing an audiometric screening system including signal generation electronics, operator controls, displays and a set of earphones. The system electronics generate left channel and right channel signals to produce complex aural stimuli. The system allows the testor to adjust and monitor the phase of the two aural stimuli, one injected into each ear of the test subject, until subject perceives the source of the sound. The system provides a digital readout of the signal phase, yielding a quantitative measure of the differential processing time of a subject's auditory system and brain side dominance.

Abstract: A method is disclosed for recovering a non-pressurized and uncontaminated fluid sample from deep in a well or the like in an elongated sampler having a sample chamber formed by valves at both ends thereof in a tubular housing for trapping the fluid sample therein comprising, (1) venting the trapped sample fluid from one of the end valves into the well having a vertical portion extending at a predetermined distance above the sample chamber for (1) preventing detrimental pressure to build-up and (2) contamination of the sample fluid during ascent to the surface. A mechanism for carrying out the above method is also disclosed.
