Patent CA-2330402-A1 (CA)
Inventor: HODGES STEVEN B
IPC: E21B47/12
Filed: 2001-01-08
Abstract: A technique for providing auxiliary conduits in multi-trip completions is disclosed. The technique has particular applicability to liner mounted screens which are to be gravel packed. In the preferred embodiment, a protective shroud is run with the gravel pack screens with the auxiliary conduits disposed in between. The auxiliary conduits terminate in a quick connection at a liner top packer. The gravel packing equipment can optionally be secured in a flow relationship to the auxiliary conduits so as to control the gravel packing operation. Subsequent to the removal of the specialized equipment, the production tubing can be run with an auxiliary conduit or conduits for connection down hole to the auxiliary conduits coming from the liner top packer for a sealing connection. Thereafter, during production various data on the well can be obtained in real time despite the multiple trips necessary to accomplish completion. The various completion and/or production activities can also be accomplished using the auxiliary conduits such as actuation of down hole flow control devices, chemical injection, pressure measurement, distributed temperature sensing through fiber optics, as well as other down hole parameters.

Title: Wdm transmitter
Inventor: IBSEN MORTEN
IPC: H04B10/564
Filed: 2000-02-18
Abstract: A WDM transmitter comprising an array of M pump lasers (10) muliplexed by an MxN multiplexer, in the form of a coupler (20), and used to feed an array of N  optically pumped fiber lasers (30) emitting at wavelengths .lambda.1, .lambda.2, ... .lambda.N. The paramater M determines the number of pump lasers as well as the number of inputs of the pump-multiplexing coupler and can be smaller or equal to parameter N that determines the number of optically pumped lasers. The fiber laser outputs are passed through N isolators (40) before entering N modulators (50) where the signals are monolithically modulated. The outputs of the modulators are passed through an array of N tunable attenuators (60). Finally all the individual channel outputs are recombined into a single output (80) in a combiner (70). The output (80) will typically lead to an optical network.
Patent CA-2365155-A1 (CA)
Inventor: SCHULTZ MARK DELORMAN
IPC: G11B21/10
Filed: 1995-11-24
Abstract: A mechanism for servowriting on a storage medium of a storage device. The storage device has a transducer and a servo loop for positioning the transducer with respect to the storage medium. At least one transition is written on a track of the storage medium, while servoing on other transitions previously recorded on the storage medium. A reference waveform is derived as a function of a closed loop response of the servo loop and a position error waveform. The position error waveform corresponds to one or more position errors of the transducer relative to the previously recorded transitions. The reference waveform is usable in writing subsequent tracks on the storage medium. Using the reference waveform for writing subsequent tracks provides a substantial rejection of mechanical disturbances by the servo loop.
