Title: Thermal cycler for automatic performance of the polymerase chain reaction with close temperature control
Inventor: WOUDENBERG TIMOTHY M
IPC: C12M1/36
Filed: 1991-11-29
Abstract: An instrument for performing highly accurate PCR employing a sample block in microtiter tray format. The sample block has local balance and local symmetry. A three zone film heater controlled by a computer and ramp cooling solenoid valves also controlled by the computer for gating coolant flow through the block controls the block temperature. Constant bias cooling is used for small changes. Sample temperature is calculated instead of measured. A heated cover deforms plastic caps to apply a minimum acceptable threshold force for seating the tubes and thermally isolates them. The control software includes diagnostics. An install program tests and characterizes the instrument. A new user interface is used. Disposable, multipiece plastic microtiter trays to give individual freedom to sample tubes are taught.

Patent CA-2398637-A1 (CA)
Inventor: PARANTAINEN JANNE
IPC: H04L12/56
Filed: 2001-01-31
Abstract: A method as described by which an application executing in an application layer of a multi-layer communication protocol forming part of a general packet radio service (GPRS) session can signal for the setup and release of Temporary Block Flow (TBF) which will not be released during application execution in silent (inactive) periods. When applications such as voice, telnet or web browsing have specific traffic type data that have inactive periods between active periods are to be carried over GPRS, the session consists of multiple active periods. Current TBF release procedures lead to multiple TBF setups during such sessions. With the method described, a special type of TBF can be set up with special procedures for release of this TBF which greatly minimizes the need for multiple TBF setups during a session containing data transfers with inactive periods between active data transmissions.

Inventor: DAUBE FRANCOIS
IPC: G01V1/30
Filed: 2002-01-07
Abstract: A method of generating a semblance panel comprises summing two or more gathe rs of traces. The dip of the reflector is taken into account in the summation process, and this prevents semblance peaks from becoming smeared during the summation process and so allows a greater number of gathers to be used to generate the semblance panel. In an embodiment of the invention the dip is determined from the seismic data. Alternatively, the reflector dip used in t he summation process may be obtained from pre-existing data acquired at the survey location, or the reflector dip may be already known. The invention ca n be applied to seismic data containing events from more than one reflector.</ SDOAB>
