Abstract: A system enables collection of data using a radar challenging units familiar in RF tagging system in communication with RFid tags embedded in windshields associated with motor vehicles. The edge of a windshield is fabricated with a slot either before or during the manufacturing of the windshield. The slot is usable to accept an RFid tag and associated electronics. Once electronics are installed in the slot it can be sealed for tamper resistance and weather protection. Wiring providing power and data transfer to the RF tags can be routed from the edge of the windshield through rubber sealing surrounding the windshield and car frame, and be routed into internal compartments of the vehicle for applications where data/computer integration is desired. Collectable data includes: VIN, registration status, inspection status, insurance status, Amber alert, licensing information and others.

Abstract: A tool for monitoring corrosion levels within a wellbore particularly suited for remote monitoring over extended periods. The monitoring tool utilizes a thin wall electrical resistance type corrosion sensor to determine rate of metal loss within the wellbore. The corrosion sensor is preferably made of the same material as the production tubing or drill pipe of the well and is positioned to allows the fluid within the wellbore to flow over the sensor at the same rate as the fluid flows over the tubing. A reference element is incorporated into the corrosion sensor to provide primary temperature compensation. A temperature sensor provides temperature data and allows for secondary temperature compensation for the corrosion sensor. A central processing unit reads and stores the data from the three sensors into solid state memory. The probe records data at programmable time intervals.

Abstract: A surface activated multishot survey tool utilizes a dampened magnetic compass movably positioned within a probe to determine the direction of a borehole. Lamps in the probe are operable to light the face of the compass. A lens projects the image of the compass onto a movable film strip. An electrical cable is connected to the probe and is used to pass a current to the lamps and provide selective operation of the tool from the surface of the borehole. Electrical connectors are provided at each end of the probe so that the probe may be inverted within the borehole to accommodate surveys in which the angle of the borehole is greater than that at which the compass will operate without error. Because connectors are located at both ends of the probe, electrical current passes around the magnetic compass, thus creating a magnetic field about the compass.
