Abstract: An apparatus for measuring the level of fuel in a fuel tank is disclosed. The apparatus comprises an in-tank measuring system that provides an oscillating output signal generated, for example, by an oscillator such as a multivibrator, where the oscillating output signal has a frequency corresponding to the fuel level. The in-tank measuring system includes a capacitive fuel probe mounted within the fuel tank to contact the fuel. The fuel probe has a capacitance that is a function of the level of the fuel. The oscillator is configured for mounting within the fuel tank at a position in close proximity to the capacitive fuel probe. The oscillator circuit uses the capacitance of the fuel probe to generate the oscillating output signal. A communication path communicates the oscillating output signal from the clock circuit to a circuit exterior to the fuel tank.

Abstract: A system for tracking objects that include radio frequency identification (RFID) tags associated therewith. The system including a structure substantially defining an enclosure, a reflective interior of the enclosure configured for the reflection of radio signals, at least one conveyor belt that transports the objects through the structure, at least one RFID reader panel inside the structure, wherein the at least one RFID reader panel transmits a radio signal into the interior of the structure such that the radio signal will reflect off of the interior of the structure to increase a probability that the RFID tags associated with the objects that enter the structure are read, and an operator terminal that receives and stores information regarding read RFID tags from the at least one reader panel.
