Patent number: 9532284Abstract: Handoffs within a wireless communication system (20) include using a common cell definition code for each of a plurality of microcell BTSs (30, 40, 50) to facilitate handoffs between a macrocell (26) and any one of the microcells. In a disclosed example, a common cell definition code such as a PN offset or a scrambling code is used to trigger a handoff from the macrocell (26) to any one of the microcell BTSs (30, 40, 50). A mobile station locate feature identifies which of the BTSs is involved in the handoff. Another common cell definition code is used in one example to trigger all handoffs from any one of the microcells (30, 40, 50) to the macrocell (26). Soft handoff and hard handoff examples are disclosed.Type: GrantFiled: November 24, 2014Date of Patent: December 27, 2016Assignee: Alcatel-Lucent USA Inc.Inventors: Patrick Li, Victor Pan, David A.

Patent number: 7768974Abstract: In a method for generating pilot beacons for hard handoff over a border from a first environment to a second environment, the two environments using spread spectrum technology, a RF pilot signal may be received at an operational frequency used in at least the second environment. The RF signal may be downconverted to an IF pilot signal, filtered and then upconverted to a first reproduced RF pilot signal. The first reproduced RF pilot signal may be at a operational frequency used in a first environment, and may represent a pilot beacon for hard handoff between the first and second environments. The method and arrangement may be configured to receive a pilot beacon from one environment and to generate N pilot beacons, in that one environment, for up to N different operational frequencies used in another environment from which a mobile user is transiting, for hard handoff between the environments.Type: GrantFiled: February 3, 2003Date of Patent: August 3, 2010Assignee: Alcatel-LucentInventors: Patrick Li, Gregg Nardozza, Victor Pan

Patent number: 7406300Abstract: A wireless communication system includes at least one repeater antenna assembly for providing adequate RF coverage within a building, such as a home. An example repeater antenna assembly has an automatically adjustable gain that is controlled responsive to a pathloss associated with a received signal to avoid base station transceiver desensitization and positive feedback. A disclosed assembly avoids base station desensitization and positive feedback. Another disclosed technique maintains a selected minimum link budget within the building.Type: GrantFiled: July 29, 2004Date of Patent: July 29, 2008Assignee: Lucent Technologies Inc.Inventor: Victor Pan

Patent number: 7022286Abstract: A fluidic medical diagnostic device permits measurement of analyte concentration or a property of a biological fluid, particularly the coagulation time of blood. The device has at one end a sample port for introducing a sample and at the other end a bladder for drawing the sample to a measurement area. A channel carries the sample from the sample port to the measurement area, and a stop junction, between the measurement area and bladder, halts the sample flow. The desired measurement can be made by placing the device into a meter which measures a physical property of the sample—typically, optical transmittance—after it has interacted with a reagent in the measurement area.Type: GrantFiled: December 26, 2002Date of Patent: April 4, 2006Assignee: Lifescan, Inc.Inventors: John Lemke, Robert Justice Shartle, Victor Pan, Philip Cizdziel
