Patent CA-2333049-A1 (CA)
Title: Lancet apparatus and methods
Inventor: THORNE DAVID L
IPC: A61F9/007
Filed: 1999-05-11
Abstract: A one-time-use, self-powered, restricted entry lancet apparatus (10, 210) which provides a smaller incision in a surface or epidermal layers of a lancing site then in subsurface or dermal layers. Two embodiments (10, 210) of the invention are disclosed. Generally, each embodiment comprises a housing (20, 30, 220, 230), a blade component (150, 310), a rotary spring (140, 320) and an actuator (40, 240). The blade (150, 310) generally comprises a proximal portion (156, 330) and a distal section (154, 328). The proximal portion (156, 330) is disposed within the housing (20, 30, 220, 230) and is displaced laterally in a first direction during a lancing procedure. During the lancing procedure, the distal section (154, 328) is extended from the housing (20, 30, 220, 230) through an open exit slot (60, 300) and is rotated about an abutment member (170, 294, 296) of the exit slot (60, 300) to be laterally displaced in a direction opposite the first direction. This rotation about the abutment (170, 294, 296) results in an incision pattern which has a smaller cut in the epidermis than in the dermis. Thus, surface trauma is reduced, while a broad cut is made in capillary rich regions of the dermal layers.

Title: A microwave fluid sensor and a method for using same
Inventor: BRINGSVOR ARSTEIN
IPC: G01N22/04
Filed: 1999-06-02
Abstract: A microwave sensor for measuring of the relative proportions of fluids flowing as a mixture through a tube (4). A length (9) of said tube (4) makes up a part of said sensor (3) together with probes (6, 7) transmitting electromagnetic energy into the sensor (3) and receiving electromagnetic energy from the sensor (3). The sensor (3) uses resonance at a resonant frequency (fm) below the cut off frequency limit (fnm) of the tube (4). The sensor (3) is provided with a radially extending, conducting internal fin (5) along the axis (10) of the tube (4). This fin (5) may be of regular or irregular shape and may be fixedly or detachedly arranged, e.g. through a slot (13). The invention also relates to a method for determining the relative proportions between two fluids, by first measuring the permittivity of the mixture and then comparing this value to a calibrated value; and also comprises an amplifier to enhance the sensor's measurement range.

Title: Solid state protection circuit for electrical apparatus
Inventor: BERKOPEC WILLIAM EDWARD
IPC: H02H1/04
Filed: 2001-04-12
Abstract: Electrical equipment (14) is safeguarded from damage due to faults by a circuit that provides several levels of protection. A semiconductor switch (18) and a current sensor (24) are placed in series with the electrical equipment (14). When the current to the equipment exceeds a first threshold for a predefined period of time, the semiconductor switch (18) is rendered non-conductive until the circuit is specifically reset. When the current to the equipment exceeds a greater second threshold, a pulsed signal alternately places the semiconductor switch (18) in conductive and non-conductive states so that the average current applied to the equipment (14) is within an acceptable level. Should the current exceed an even greater third threshold, the semiconductor switch (18) is immediately rendered non-conductive until the circuit is manually reset.

Title: Explosion prevention system for internal turret mooring system
Inventor: NANDI ASIS
IPC: E21B43/01
Filed: 2000-03-03
Abstract: A method and apparatus for ensuring against explosion of the gaseous atmosphere of a closed chamber, such as the QDCD room of an internal turret of an offshore production and offloading buoy wherein the closed chamber has production risers and conduit connectors that represent a potential source of flammable gas. The method comprises mixing and diluting the oxidant content of the air by introducing within the closed chamber a sufficient quantity of inert gas to render the mixture of the air and any flammable gas noncombustible regardless of the flammable gas content of the mixture. The method includes removal of the non-combustible mixture of air and any flammable gas from the closed chamber by purging thereof to the natural atmosphere, while introducing inert gas, thereby leaving a substantially inert atmosphere within said substantially closed chamber. The turret system provides for control of the gaseous atmosphere within the closed chamber at all modes of turret operation, including the idle, on-line and ventilation modes and also provides for gas pressure control to accommodate normal operating conditions and conditions of gas leakage into the chamber.
