Patent CA-2453141-A1 (CA)
Inventor: BOOKSH KARL S
IPC: G01N33/68
Filed: 2002-07-09
Abstract: An optical biosensor carries one of more affinity legends or binding members that bind specifically to a marker being monitored. Light directed along optic fibers illuminates a surface plasmon resonance ("SPRN") probe surface on which is immobilized the binding member. A spectrophotometer receives light reflected back along the fiber optic path and provides wavelength information indicative of the absence or presence of surface plasmon resonance indicative of the bound marker in known SPR manner. The probe is used in vitro or in vivo. When used in vivo the fiber optic light path comprises a catheter that directs the probe to an implant site. For in vivo implantation a housing houses the probe at the implant site and is adapted to filter out larger particles that would adversely affect with the spectral analysis. In one embodiment the probe has two regions on its surface. The first region has no immobilized binding member. The second region does have the binding member immobilized on it. Light returned from the first and second regions can be compared. The presence or absence of a marker bound by the binding member on the second surface is apparent in the similarity or dissimilarity of the spectral information returned form the two regions. The probe can monitor blood, spinal fluid, mucous membrane, wound tissue, implanted organs, urine, and other substances for the presence of a marker which may be indicative of a medical condition in an animal or human subject.

Filed: 2002-08-29
Abstract: An elongated catheter device with a distal balloon assembly is adapted for endovascular insertion. Coolant injected through the device may directly cool tissue contacting the balloon (212), or may cool a separate internal chamber.  In the first case, the coolant also inflates the balloon, and spent coolant is returned to the handle via a return passage extending through the body of the catheter.Plural balloons may be provided, wherein a secondary outer balloon (212) surrounds a primary inner balloon (203), the primary balloon being filled with coolant and acting as the cooling chamber. The secondary balloon is coupled to a vacuum return lumen (205) to serve as a robust leak containment device and thermal insulator around the cooling chamber.

Patent CA-2465694-A1 (CA)
Inventor: CORNILS GERD
IPC: B60J1/00
Filed: 2002-11-07
Abstract: A method for producing a profiled bead made of a plastic, particularly of a polymer, on a piece, particularly on a window pane. In the method at least a partial portion of an edge region or lateral face region of a surface of the piece is brought into contact with a forming face. The plastic is deposited stuck to at least part of the periphery of a surface of the piece untouched by the forming face and the external dimensions of the profiled bead formed are also defined by the forming face. The forming face is pressed against the edge region or lateral face region of the fixed piece using a flat support, the shape of which can vary under the pressure of a fluid. This then gives a better matching of the forming face to the contour and to any dimensional discrepancies of the piece.

Title: Microbolometer detector with high fill factor and transducers having enhanced thermal isolation
Inventor: WOOLAWAY JAMES T
IPC: G01J5/20
Filed: 2004-05-12
Abstract: In a microbolometer detector the individual transducers in the focal plane array are supported by leg members that are attached to the underlying readout integrated circuit (ROIC) chip at locations underneath transducers other than transducer which they support. A variety of configurations are possible. For example, the leg members may be attached to the ROIC chip at locations under adjacent transducers on opposite sides or on the same side of the supported transducer, or at locations underneath transducers that are not immediately adjacent to the supported transducer. In this way the effective length of the leg members and therefore the thermal isolation of the transducer they support can be increased.

Title: Esp performance optimization control
Inventor: GUENTHER ROBERT N JR
IPC: B03C3/68
Filed: 2005-02-14
Abstract: A gas separation apparatus which uses electrostatic precipitators and a DC power supply is controlled to optimally remove moderate to high resistivity ash. The DC power supply is pulse width modulated to maximize the product of the peak electric field and the average electric field. The method used to optimize operation includes selecting initial on and off times for the power supply, operating the power supply using the initial off and on times, and progressively decreasing the off time. A determination is made whether the off time may be further decreased. Ultimately, the on and off time intervals that produce the highest peak and average voltage are determined, and the system is operated using these parameters. A procedure may be periodically repeated to monitor the process and detect if there has been a change in the system that would require new time intervals. The novel separation apparatus and control method offer particular synergy when applied to the effluent stream from a coal-fired electric power plant or other similar gas streams.

IPC: F22B37/22
Filed: 2003-08-28
Abstract: Disclosed is a steam generator (1) in which a continuous evaporating heating area (8) is disposed within a heating gas duct (6) that is penetrated in a nearly horizontal direction (x) by a heating gas. Said continuous evaporating heating area (8) comprises a number of steam-generating pipes (12) that are connected in parallel and are penetrated by a flowing medium (D, W) and is configured such that a steam-generating pipe which is heated more than another steam-generating pipe (12) of the same continuous evaporating heating area (8) has a higher throughput of the flowing medium (W) than said other steam-generating pipe (12). The aim of the invention is to create a steam generator which provides a particularly high degree of stability of flow during operation of the continuous evaporating heating area (8) while keeping the structural complexity and design comparatively simple. Said aim is achieved by means of a discharge collector (20) which is mounted downstream of the steam-generating pipes (12) of the continuous evaporating heating area (8) on the side of the flowing medium, and the longitudinal axis of which is located essentially parallel to the direction (x) of the heating gas.
