Title: Home zone service method for mobile telephone subscribers in mobile radio communication system
Inventor: PARK YOUNG-SOO
IPC: H04L12/14
Filed: 2000-07-03
Granted: 2008-01-08
Abstract: Disclosed is a home zone service method for assigning a specified zone to a mobile telephone subscriber and charging the subscriber at different billing rated accordingly as the subscriber makes a telephone call inside or outside the zone. According to the home zone service method, a zone which is defined by a first measurement value and a second measurement value as a sub-sector is determined by measuring a round trip delay from a fixed location in a sector of a cell to the neighbor base stations to which the subscriber belongs, so that a predetermined home zone database including the first value and the second value is prepared. The round trip delay is measured from a specified signal if a portable mobile terminal of the subscriber generates a request signal to establish a call connection. Then, it is determined whether the subscriber is located inside the sub-sector if the measured round trip delay falls between the first value and the second value of the home zone database.

Patent CA-2360966-C (CA)
Inventor: HEADWORTH COLIN STUART
IPC: E21B33/076
Filed: 2000-01-18
Granted: 2005-09-13
Abstract: The present invention provides a system including a spoolable compliant guide (30), injector (22, 23), and lubricator (40) to obtain vertical access to any oil well (51) and to insert coiled tubing (21) therein to. The spoolable compliant guide provides a substantial distance between the injector and the annular well seal (35) at the lubricator and functions as a crimp or bend resistor for the coiled tubing therein facilitating the imposition of compression forces thereon. This enables the injector to be conveniently positioned remote from the wellhead (50), not necessarily vertically above the wellhead, on the facility with the wellheads or on an entirely separate facility, vehicle or vessel. Wellheads on land, offshore or underwater can all be accessed. Pressurized well fluids are prevented from entering the spoolable compliant guide thus decreasing the risks associated with its damage, failure or emergency disconnection.

Filed: 2000-03-02
Granted: 2004-09-21
Abstract: A communication device (100) contains a plurality of bandmaps in a memory (102). Upon powering up the device, the device first scans frequencies listed in a learned bandmap (104). If no suitable carrier signals are detected, the device scans the frequencies listed in a present regional bandmap (106), and this scan may be repeated several times.  Upon failing to detect a suitable carrier at any of the frequencies listed in the present regional bandmap, the device alternates between scanning the present regional bandmap and segments of a world wide bandmap (108), which is a comprehensive list of all possible frequencies at which the device may operate. If a carrier is detected indicating the device is in a new region, the regional bandmap corresponding to the new region is set to be used as the present regional bandmap.
