Abstract:

A method and computer-readable medium for performing predictive name completion, categorizing call lists and accessing dispatch ID numbers in a database for dispatch dialers is provided. The method for performing predictive name completion includes recognizing a portion of a dispatch ID input by a user; determining a name associated with a dispatch ID, based on the portion of the dispatch ID input by the user, and displaying the name. The method for categorizing call lists includes determining a type of each of a plurality of the dispatch calls; and placing each of the plurality of dispatch calls in one of a plurality of categorized lists, based on the type of each of the plurality of dispatch calls. The method for accessing dispatch ID numbers in a database includes establishing a mirror database including the dispatch ID numbers; and searching the mirror database for particular dispatch ID numbers.

Filed:

Jun 11, 2001

Appl. No.:

09/878770

Inventors:

Maxim Kiselev - Sterling VA, US
Duc Lai - Chantilly VA, US

International Classification:

G21G001/10

US Classification:

376/195000

Abstract:

A process and apparatus for producing the F isotope from water enriched with the O 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 F, water in the target loop is diverted through an F 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 F.
