Title: Gyroscopically-oriented survey tool
Inventor: BLAKE ERIK
IPC: E21B47/022
Filed: 2004-12-13
Abstract: A gyroscopically-oriented survey tool, includes a housing having an axis.  Three accelerometers are mounted in the housing with their axes set orthogonally. A  first of the axes is aligned to the axis of the housing. A second of the axes is perpendicular to the first. A third of the axes is perpendicular to both of the first and the second. Three gyroscopes are mounted pseudo-orthogonally in the housing with their axes set at relative angles of other than 90 degrees. None of the axes of the gyroscopes are mounted parallel to the axes of the accelerometers. This configuration permits data from the accelerometers to be used to check the quality of data from the gyroscopes.

Title: Membrane-based assays using time-resolved fluorescence
Inventor: WEI NING
IPC: G01N33/58
Filed: 2003-07-10
Abstract: A membrane-based assay device for detecting the presence or quantity of an analyte residing in a test sample is provided. The device utilizes time-resolved fluorescence to detect the signals generated by excited fluorescent labels. Because the labels can have relatively long emission lifetime, short-lived background interference can be practically eliminated through delayed fluorescence detection. In addition, the resulting fluorescent reader can have a simple and inexpensive design. For instance, in one embodiment, the reader can utilize a silicon photodiodide and a pulsed light-emitting diode (LED) to accurately excite labels and detect fluorescence on a membrane-based assay device without requiring the use of expensive components, such as monochromators or narrow emission band width optical filters.

Title: Power steering apparatus
Inventor: KAJI HIROAKI
IPC: B62D5/065
Filed: 1997-08-13
Abstract: A motor is stopped when a steering angular speed is not greater than a stop threshold VS and a motor electric current value Im is kept within a motor stop range .DELTA.I for a predetermined time period. The value of a steering torque increases as the motor electric current value Im increases.  Therefore, the motor can assuredly be stopped when the steering torque is small. Further, when the motor is off, the sensitivity for motor actuation with respect to a change in the steering angle is set higher as the value of the steering angle increases.
Patent CA-2499731-A1 (CA)
Inventor: BITTAR MICHAEL S
IPC: G01V3/28
Filed: 2003-09-18
Abstract: The specification discloses a system and related method for obtaining electromagnetic resistivity logs of a formation having fixed depths of investigation that differ from the actual depths of investigation for the tool. The system and related method comprises calculating actual invaded zone and formation resistivities, and then using least-squares curve fitting techniques to find a function that models the relationship between the physical spacing of the transmitters and the depths of investigation. Using the function, it is possible to find a transmitter-to-receiver spacing that, though not actually used, would give the desired depth of investigation. This transmitter-to-receiver spacing is then used in combination with a second function, determined using least-squares curve fitting methods, which models the relationship between the transmitter-to-receiver physical spacing and the measured resistivity to obtain the resistivity reading at a fixed depth of investigation. This may be done for a set of desired depths of investigation, and may also be done for a set of elevations within the borehole, to create a fixed depth of investigation log that may be easily compared to other resistivity logs, such as those created by a wireline device.

Inventor: SUGITA TAKAHIDE
IPC: H04B10/03
Filed: 2003-01-03
Abstract: Disclosed are the multiplex communication system and the method therefore. A fault detection part of a duplex switching device detects it as generation of fault when recognizable signals are not detected from a connected line within a prescribed time. When the fault detection part detects the generation of fault in the present system line, the line switching part switches the lines from the present line to the standby line to perform communication between a terminal device and another terminal device therethrough. Also, the fault detection part notifies the generation of fault to the other duplex switching device after a prescribed switching protection time has passed from the time of the fault detected by the fault detection part, so the selection of the lines becomes consistent.

Patent CA-2521981-A1 (CA)
Title: Mobile television receiver
Inventor: LINK HERMANN
IPC: H04N19/89
Filed: 2005-09-26
Abstract: The present invention relates to the reproduction of a television signal on a distant reproduction device. The received television signal is encoded and transmitted in a digital data format over a communication link to the reproduction device. The reproduction device decodes the received video information for display on a display screen. The present invention is particularly intended for use in mobile vehicles, coaches and trains, where the signal strength of a received television signal during travel is continuously varying and signal distortions occur frequently. In order to reduce the effect of signal distortions on the perceived image and audio quality, the present invention inserts a compressed pre-stored video or audio data into the data stream transmitted from the television receiver to the reproduction device upon detection of a television signal distortion. Thus, the decoding procedure at the display device can be maintained in spite of a received a television signal of insufficient signal strength.
