Title: Self energized packer
Inventor: MURRAY DOUGLAS J
IPC: E21B33/12
Filed: 2007-01-18
Abstract: A packer or plug features a main sealing element (12) that swells after a delay long enough to get it into proper position. A sleeve (14) eventually goes away to let the well fluids at the main sealing element to start the swelling process until contact with the surrounding tubular or the wellbore is established. Other sleeves (18,20) that are disposed above and below the main sealing element preferably swell, but mainly in a longitudinal direction against the main sealing element to increase its contact pressure against the surrounding tubular or the wellbore. The longitudinally swelling members may also be covered to initiate their growth after the main sealing element has started or even completed its swelling action. The longitudinally swelling members can be constrained against radial growth to direct most or all of their swelling action longitudinally. Extrusion barriers above and below the main sealing element can optionally be used.

Abstract: An ion guide includes multiple stages. An electric filed within each stage guides ions along a guide axis. Within each stage, amplitude and frequency, and resolving potential of the electric field may be independently varied. The geometry of the rods maintains a similarly shaped field from stage to stage, allowing efficient guidance of the ions along the axis. In particular, each rod segment of the ith of stage has a cross sectional radius ri, and a central axis located a distance Ri+ri from the guide axis. The ratio ri/RIis substantially constant along the guide axis, thereby preserving the shape of the field.

Abstract: An optical mirror element includes an optically transmissive element having a first surface and a second surface, and a reflective coating layer on the first surface that defines a mirror surface. A first portion of the first surface does not include the reflective coating layer such that the first portion defines an optically transmissive window in the mirror surface. A method of forming an optical mirror element having a window portion includes providing an optical element, masking a first portion of a first surface of the optical element, and thereafter applying a reflective coating to the first surface so as to define a reflective surface, wherein the masked portion defines a transmissive region in the reflective surface. The exposed portion of the first surface may be coated with an anti-reflective coating, either before or after the reflective coating is applied.

Inventor: JOHNSTON DEREK
IPC: G01N27/416
Filed: 2008-10-27
Abstract: A sensor supervision system for periodically providing a test to accesses the status of a gas detection sensor, such as a carbon monoxide (CO) sensor, is provided.  To access the status of the CO sensor, a processor provides a voltage to the sensor supervision system, such that a voltage is applied to CO sensor, charging the CO sensor.  The status of the CO sensor is accessed by determining the change in the voltage charge of the CO  sensor between two sampling time points. If the first sample voltage is substantially equal to the second sample voltage, i.e., a substantially constant voltage, the carbon monoxide sensor fails the test. However, if there is an change is the voltage change between the first and second sampled time points, the CO sensor passes the test.

Abstract: A quantitative method for determining structural and functional characteristics and/or the pathological status of a tissue includes the steps of generating data for a dynamic optical curve over a period of time based on an optical property of a tissue, or portion thereof, that has been exposed to a biomarker and, based on the data, determining a value of a dynamic optical parameter. The value of the dynamic optical parameter is compared with reference values of the dynamic optical parameter known to be linked to a structural or functional characteristic and/or the pathological status of the tissue; and based on the comparison, a structural or functional characteristic and/or the pathological status of the tissue, or portion thereof is determined. A computer readable medium holds computer program instructions for carrying out this method. Reference values can be calculated by measuring dynamic optical properties from known representative tissue samples. Preferred tissue samples include epithelial and cervical tissue samples. Preferred methods involve diagnosing and/or grading neoplasia and/or HPV infection and/or calculating nuclear to cytoplasmic ratios of the cells in the tissue sample.
Patent CA-2653269-A1 (CA)
Title: Communication system
Inventor: OSHIMA MITSUAKI
IPC: H04N19/89
Filed: 1994-03-25
Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram The input signal is divided into, two, first and second, data streams The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the signal points to other positions in the space diagram expressed at least in the polar coordinate system. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into, low and high, frequency band components which are designated as a first and a second data streams respectively. Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability. Furthermore, a communication system based on an OFDM system is utilized for data transmission of a plurality of subchannels, wherein the subchannels are differentiated by changing the length of a guard time slot or a carrier wave interval of a symbol transmission time slot, or changing the transmission electric power of the carrier.
