  • Publication number: 20060229085
    Abstract: A communication module capable of simultaneously providing communication and positioning information is provided. The communication module includes a processor with an integrated positioning receiver. The processor transmits and receives communication information, such as interconnect voice, dispatch voice, or data, using a first transceiver. The integrated positioning receiver is coupled to a second transceiver to transmit positioning information.

  • Patent number: 6748562
    Abstract: A test program generates transmit vectors (stimuli) and receive vectors (expected responses). The transmit vectors are applied to the DUT, while the receive vectors are treated as comparison values used to decide if a response from the DUT is as expected. While programming a FLASH part the test program uses TAG RAM techniques to maintain a BAD COLUMN table in one of the memory sets. This BAD COLUMN table is addressed by the same address that is applied to the DUT. If an OMIT BAD COLUMN mode is in effect, entries in this table are, by automatic action of the memory tester hardware, obtained and used to supply a replacement programming data value of all 1's that will produce an immediate and automatic indication of successful programming from the DUT. This prevents spending extra time programming a column that has been determined to be bad, without requiring an alteration in the internal mechanism of the test program.

  • Publication number: 20030194039
    Abstract: A process and apparatus for producing the 18F isotope from water enriched with the 18O isotope using high energy protons from a cyclotron. The apparatus has a cyclotron target cavity that is connected to a fluid loop that contains a water reservoir, pump, and pressure regulator. Water is continuously recirculated through the target cavity to increase reliability. After irradiation long enough to produce a desired amount of 18F, water in the target loop is diverted through an 18F extraction device before being returned to the target loop. The returning water may also be purified and additional water added to the target loop as needed to permit continuous irradiation and production of 18F.
