Filed: 1998-08-05
Abstract: PURPOSE: Hangul character transmitting/receiving method in a wireless paging system applies two kinds of character system methods which are 7-bit character code method and 8-bit character code method in a wireless paging system, without using additional Hangul code converter. CONSTITUTION: The method inserts at least one field into a data if the data is a text as of a character code, and thus discriminates 7-bit character transmission code system and 8-bit character storage code system. The method transmits a data stream as a corresponding bit unit, and wirelessly transmits the data stream. A microprocessor of each pager determines whether the received data is a text of character code or not. If the text is not determined, the microprocessor uses another data format. If the test is determined as the text, the method determines 7-bit character transmission code or 8-bit transmission code. A corresponding data is discriminated as 7-bit unit or 8-bit unit through 7-bit or 8-bit character code table, and displays it with a character. Thereby, Il8N (Internationalization) standard is accommodated in two-byte character system, a Hangul message capability is made under a low level, and E-mail character system is applied as it is.

Filed: 1997-04-04
Abstract: PURPOSE: A pump-off controller for beam typed pumping unit is provided to draw an oil well production fluid from a base rock layer underground for shutting off in case of a low production fluid of the oil well. CONSTITUTION: The operation of an oil well pumping unit control system (20, 200) is governed by a computerized automated control unit (88) that receives flow rate measurements from a Coriolis flow meter (28). The control unit causes production from a beam pumping unit (22) to cease when measurements from the Coriolis flow meter indicate a decline in the pump efficiency. The decline in pump efficiency indicates that a production fluid level (136) in the production tubing (108) has fallen below the uppermost point of travel for the pump plunger (122). Production from the well is, accordingly, shut-on to afford the reservoir sufficient time to build the pressure and corresponding fluid level that is required to recommence production operations.
