Vehicle performance monitoring system
New Patents for collecting the secondary light radiation, or means for collecting solar induced secondary light radiation, spectral analysis means for analysing the spectrum of the secondary radiation, and a high resolution, multi-element digitizing detector for recovering the analyzed secondary radiation. The detector has a plurality of detection channels positioned across the spectrum of the backscattered primary radiation and emitted secondary radiation, the channels being software configurable and under the control of a digitally addressable computeroperated controller. The concentration of used channels across the plurality of channels is adjustable and increasable in the regions of the spectrum of greatest interest and decreasable in the regions of least interest.
4945362 MICROWAVE SHIELDING FOR SATELLITE EARTH STATIONS Bernhard E Keiser assigned to The Reinforced Earth Company A construction for shielding an item against interference from a microwave radio frequency radiation is disclosed, having a wall structure adapted to minimize radio frequency interference in the vicinity of an antenna. The wall is composed of a plurality of modular wall panels, each having a layer of electrically conductive materials that substantially reflects interfering electromagnetic microwave signals. The wall structure includes a top construction creating a thin, horizontal gap in the conductive material at the wall's top that acts to control diffraction over the wall. In the preferred embodiment, the layer of electrically conductive material is a mesh of expanded metal embedded in the wall modules. The gap comprises the space between the top of the mesh and a pair of vertically adjustable metal strips mounted on the wall. In the preferred embodiment, the wall panels are precast concrete that may be horizontally positioned with a joint allowing up to 180 degrees of relative movement.

A sidestream pipeline, adapted for attachment to a mainstream pipeline, is provided with end closures to permit the introduction of mechanical cleaning devices or chemical compositions to the sidestream pipeline to remove biofilm and treat corrosion-causing constituents; also provided are a plurality of removable coupons closely fitting within holes in the sidestream pipeline wall, and duplicating the material and configuration of the interior surface of the mainstream pipeline. The coupons can be individually withdrawn from the lowermost surface position during cleaning operations to avoid contact with the mechanical cleaning devices and can be isolated from teh chemical treatment. The coupons are removable for laboratory study and analysis.
4945759 VEHICLE PERFORMANCE MONITORING SYSTEM Gary F Krofchalk, Richard F Dickey, Courtne Hall assigned to Krofchalk Gary F Apparatus for monitoring the operating performance of a vehicle. The vehicle speed, engine operating speed and manifold pressure of the vehicle are compared to corresponding preset threshold values. The total time during which each of the vehicle speed, engine operating speed and manifold pressure exceed its threshold value is recorded and provided to the driver in a realtime display. The total time during which the engine is operating and the total time during which the engine is idling are also recorded and provided to the driver in a real time display.
4945760 COMBINED MOTOR TESTER AND PULSE TRAIN MONITOR FOR STEPPER MOTORS Thomas F Hornung A combined stepper motor tester and pulse train monitor is disclosed for use with a vehicle engine idle air control system. The motor tester comprises a driver pulse generator for generating a pair of pulse trains for energizing the two coils of a stepper motor. It is provided with a manually actuated switch for controlling the phase sequence and time duration of the pulse trains applied to the motor. The operation of the motor by the motor tester, with the vehicle engine run-
