  • Patent number: 7209808
    Abstract: A License Sanction Enforcement Systemâ„¢ technology that includes at least one sensor worn by an individual to be monitored and a data storage unit. The sensor can detect directional angle and acceleration motion. The data storage unit is coupled with the sensor and stores the angle kinematic data detected by the sensor. The device determines whether the individual is operating or has operated a motor vehicle based upon analysis of the angle and acceleration data, and creates a record in the data storage unit of each occurrence that operation of a motor vehicle is detected. Alternatively, the data storage unit may be used to store the raw detection data, which can be transferred to an external data processing device for analysis.

  • Patent number: 4524607
    Abstract: A system and method for detecting, and then specifically locating, a leaking tube or tubes from among a plurality of tubes which extend through a chamber and are accessible at their opposite ends from outside the chamber, such as, for example, cooling tubes of a steam condenser. The system includes a reservoir containing a supply of tracer fluid, a plurality of conduits forming a matrix which releases tracer fluid in a controllable manner into predetermined groups of tubes without interruption of the flow of normal process fluid through all of the tubes, and a detector for sampling process fluid normally flowing through the chamber for the presence of tracer fluid, the detection of tracer fluid being indicative of a leak and the capability of controllably releasing tracer fluid to the tubes permitting the localization of which specific tube is leaking.
