A precision pump for moving small volumes of fluid includes an electromagnet in which is reciprocally mounted an armature carrying a diaphragm on one end such that upon reciprocal movement of the armature an alternating high and low pressure can be created in a pumping chamber to move fluid through the pump. In one embodiment of the pump, the electromagnet drives the armature in one direction and a spring returns the armature to effect the reciprocating movement while in a second embodiment a pair of electromagnets are axially aligned and cooperate with a pair of magnets on the armature to alternately move the armature in a linear reciprocating motion as current is alternately applied to the electromagnets.

A breath alcohol detector measures and compensates for distance between the mouth of the individual exhaling breath into the ambient air and the detector, the atmospheric pressure, and the temperature. Blood alcohol content information is calculated using these compensation factors and a signal obtained from an electrochemical fuel cell which is indicative of the amount of alcohol or other gas contained in the sample. The detector also includes a reciprocally acting electromagnetically energized motor which drives a diaphragm pump to draw the sample into the electrochemical fuel cell.

The oil field lease management and security system and method of the present invention for monitoring oil field equipment and for communicating with authorized operators. The system of the present invention includes a plurality of transducers connected to the equipment for sensing operational parameters of the equipment such as fluid levels in oil field storage tanks, a plurality of controllers connected to the equipment for controlling operational components of the equipment such as determining when an oil tank is filled and activating a shut-off valve to prevent further filling of the tank, a communication access panel for allowing an authorized operator to interface with the system, and a monitoring system interconnected with the transducers, the controllers, and the communication access panel for periodically monitoring each of the transducers and the communication access panel wherein the monitoring system is capable of storing transducer information corresponding to the operational parameters from the transducers such as the levels of oil in the storage tanks and operator information from the communication access panel such as the operator's password and access code.
