US Patent:

52413055, Aug 31, 1993

Filed:

Jul 9, 1991

Appl. No.:

7/737812

Inventors:

Anthony C. Fascenda - Pacifica CA
Daniel L. Gregg - San Francisco CA

Assignee:

Newspager Corporation of America - San Francisco CA

International Classification:

G08B 522

US Classification:

34082544

Abstract:

A pager based information system (2) is used to transmit both conventional individual and group messages (using pager capcodes (76) for pager identification) and three types of unconventional multi-recipient (M-R) messages (using database ID's (68), multi-level group (MLG) ID's (78) and M-R group ID's (46)), all using the conventional POCSAG pager transmission format. Operation of the pager (6) is software controlled through the use of a microprocessor (8) and RAM (16); auxiliary chips are not needed because of the relatively slow transmission speeds. Authority to receive the M-R messages is provided at the time of manufacture (electronic serial number (ESN) (74)) or via broadcast (database ID's, MLG ID's and group IDs). Database messages are stored in pager RAM in a hierarchical or tree structure. The software controlled pagers permit the over-the-air modification of the operation of selected pagers, such as the addition or deletion of group IDs and the change in the tree structure of the database area of RAM (typically through the transmission of database messages).

Appl. No.:

8/076303

Inventors:

Anthony C. Fascenda - Pacifica CA
Daniel L. Gregg - San Francisco CA

Assignee:

Newspager Corporation of America - South San Francisco CA

International Classification:

G08B 522

US Classification:

34082522

Abstract:

A pager system in which individual pagers have a database is disclosed. The database can be updated by transmitting a mask code and update data. The mask code indicates a mask stored in the individual pager itself which receives the data. Using the mask code, the mask is identified and used to indicate positions in the database where data is to be written.

International Classification:

H04Q 700

US Classification:

34082544

Abstract:

A pager based information system is used to transmit both conventional private messages (using unique pager IDs) and two types of unconventional multi-recipient (M-R) messages (using database IDs and group IDs), all using the conventional POCSAG pager transmission format. Operation of the pager is software controlled through the use of a microprocessor and a RAM; auxiliary chips are not needed because of the relatively slow transmission speeds. Authority to receive the M-R messages is provided at the time of manufacture (database IDs) or via broadcasts (group IDs). Database type M-R messages are stored in the pager RAM in a hierarchial or tree structure. The software controlled pagers permit the over-the-air modification of the operation of selected pagers, such as the addition or deletion of group IDs and the change in the tree structure of the storage area for the database messages. The pager includes a real time pager clock which is update by pairs of broadcast time messages, the second having a time correction for the first.

Assignee:

Dataspeed, Inc. - Burlingame CA

International Classification:

G08B 112

US Classification:

340988

Abstract:

A system for detecting the location and identification of a number of vehicles at multiple points on a given track against a time gauge which includes an on-board transmitter on each vehicle of a unique identifying frequency, spaced receiving circuit elements along the track at multiple points connected to individual transmitters to receive and modify the identifying signal and transmit the signal to a programmed computer for translating the multiple signals of the different unique identifying frequencies into signals ascertainable on a portable hand apparatus selectively to indicate the speed of any selected vehicles as in a race, and to keep track of position standings and lap times.
