HIGH RESOLUTION TIME INTERVAL COUNTER The U. S. Department of Energy (DOE), its laboratories and production facilities are committed to helping businesses in the United States to improve the cycle from new ideas and product innovation to product development and commercialization. In order to achieve this goal, the DOE has put in place a program to transfer technologies developed at its laboratories to the private sector for commercial applications. DOE's objective in doing this is to establish mutually beneficial partnerships that can leverage advanced technologies and enhance the U.S. position in the ever-changing global marketplace. Sandia National Laboratories (Sandia) is one of the participating laboratories in this program. By this announcement, Sandia is soliciting expressions of interest from U.S. businesses for potential licensing of the following technology for a which patent applications has been filed with the U.S. Patent Office. Sandia National Laboratories has patented an invention called "High Resolution Time Interval Counter" (U.S. Patent #: 5,333,162). It is an electronic circuit that measures time between two events to very high resolution while using small, inexpensive, low power circuitry. Because of the small size, low power consumption, and potentially low cost of this device, it would find use in many commercial applications where current technology would not be practical. The specification for the device is as follows: 0.2 nanosecond resolution 0 to 20 microsecond measurement range Less than $15 parts cost 100 mW power consumption Approximately 3 sq.in. of printed wiring board space In addition to improving the performance/cost of products that directly measure the time between events such as electronic time interval measurement instruments, this circuit could also be utilized in combination with other electronic circuitry in a host of other applications. A working prototype of the application of the time interval counter is available at Sandia for those interested in seeing a demo of the same. Some of these potential application areas include: miniature active infrared ranging surveillance system, miniature pulse-echo radar surveillance system, miniature ultrasonic sensor for remote applications, ultrasonic chemical sensor, liquid level sensor, collision avoidance, etc. This is not a solicitation. Interested parties are invited to submit a letter of interest providing information about the company, areas of potential application for the technology and the point of contact (including address, telephone and fax numbers). Letters should be sent to: C. V. Subramanian, MS 9141, Sandia National Laboratories, P. O.Box 969, Livermore, CA 94551 (FAX:925-294-3389) E-MAIL: C. V. Subramanian, cvsubra@sandia.gov.
