Inventor: AHMADI BABAK
IPC: G06F17/30
Filed: 1995-12-11
Granted: 2007-05-22
Abstract: A computer-implemented method for information organization, wherein atomic information can be both static and dynamic, but the compound information (e.g., associations, groupings, sets, etc.) of such atoms always remain dynamic.    Unless otherwise directed, a compound information entity is always dynamically determined and generated. This determination is based on the processing of a defined condition, wherein all atoms qualifying the condition are included in the compound. This dynamic determination eliminates the need to "update" the compound, when atoms and/or compounds common to two or more compounds are changed.   Further, each information compound can be dynamically generated based on an existing definition for that compound.

Granted: 2001-01-16
Abstract: There is disclosed a method of selecting characters from a group of characters assigned to a single key, in particular a key of a telephone dialling keypad. Actuation of a key (8; 16) invokes a cursor controlled display of the characters (2; 18). The cursor is held at a particular position (11) while a key is actuated within a predetermined time interval (t1; 6, 7). The character string corresponding to a particular key actuation is read (18) and is used for the retrieval of the closest matching data entry from memory means (19). If the key is not further actuated within this time interval (t1), the cursor is moved to a next position (22), provided the selected character string matches any of the data entries of the memory means (20, 21). The retrieved data entry may be used, inter alia, for automatic dialling purposes. The method is applied in a telephone set having memory means containing subscriber data.

Abstract: A field identification signal generating circuit for a receiver for receiving a high-definition signal, and a method therefor, are provided.  According to the method, a first correlation value is calculated, between the input high-definition signal and a first reference signal same as a first known signal. A timing control signal, synchronized with a second known signal whose phase is alternately inverted in every field, is output when the first correlation value is greater than or equal to a predetermined value.  A second correlation value is calculated, between the input high-definition signal and a second reference signal same as the second known signal.  Information on the polarity of the second correlation value is output.  A field identification signal is generated on the basis of the polarity information on the second correlation value which is synchronized with the timing control signal.  Therefore, the field identification signal generating circuit can be realized with simple hardware.

Granted: 2008-12-02
Abstract: Methods and apparatus for generating and clearing an excessive bit error rate alarm are provided and utilize a window algorithm.    Data blocks of telecommunications signal are monitored in an "idle state" (12). A counter counts the number of incoming blocks in a window such that the block having a code violation count (CV) meeting or exceeding a threshold (CVSET) (14). If the count meets or exceeds its own threshold (x) (26), an alarm state is entered and an alarm is set (30). Otherwise, the system returns to the "idle state" (27). In the alarm state, a clearing counter (CC) counts the number of incomming blocks in the window having a CV of CVCLRR or less (34). If the CC count meets a third threshold value (Y) (45), the alarm is cleared and the system returns to the idle state. Otherwise, the system reverts to the alarm state (47).

Granted: 2003-02-18
Abstract: An International Mobile Subscriber Identity (IMSI) number transmitted by a mobile station is first analyzed by the serving mobile switching center (MSC) associated with an International Telecommunication Union (ITU)-based SS7 network. If the received IMSI number instead belongs to an American National Standards Institute (ANSI)-based SS7 network, the serving MSC prepends a country code representing the mobile subscriber to the received IMSI number.  The least significant digits of the resulting number are further truncated to conform to the E.214 standard (the maximum length of fifteen digits). A Mobile Application Part (MAP)-based signal, such as a location update signal, is transmitted utilizing the generated E.214 number as the Signaling Connection Control Part (SCCP) called party number parameter and routed to an international gateway connecting the ITU-T-based SS7 network with the ANSI-based SS7 network. The international gateway deletes the country code prepended to the IMSI number from the received MAP signal and forwards the MAP  signal to the destination node within the ANSI-based SS7 network.
