Abstract: A clip applier and method for ligating a tissue structure is provided. The applier has a two stage actuation. In the first stage, a tissue structure is positioned into the jaws of the clip applier The jaws close and lock to a preset force to compress and temporarily occlude the tissue structure. if satisfactorily positioned, the second stage is initiated in which a clip is advanced through the shaft of the clip applier in a closed position. At the distal end of the clip applier, the clip is opened slightly to capture the pre-compressed tissue structure, and is placed over the structure. The clip is then dissociated from the business end of the instrument. Preferably the clip comprises two leg members disposed in close proximity to one another joined from opposing directions by a connecting element. The connecting element restricts separation of the leg members with opposing spring members so as to provide substantially uniform parallel deflection of the leg members from each other.

Abstract: An internal combustion engine has an engine unit fuelled by fuel gas through a carburettor, and also an exhaust pipe comprising a catalytic converter and an oxygen sensor or lambda cell of zirconia incorporating a platinum electrical resistance heater in a bridge circuit having a control resistance and fixed resistances.      For calibration the cell is initially operated in atmospheric air with an heater power control circuit supplying variable d.c. power output, under control of a microcontroller, to the bridge to power the heater and vary the temperature of the cell.      When the cell gives an electrical output of a predetermined reference value this is observed by the microcontroller which varies the value of the control resistance to a calibrating value RC2 at which the bridge nulls. Then the microcontroller is instructed to adopt operating mode and in accordance with its program the microcontroller sets the resistance value of the control resistance at the control value RC1 correlated by an operating function in the program with the calibrating value RC2. The values of the fixed resistances are RA and RB respectively. When the cell is placed in the exhaust pipe and control means comprising the microcontroller and the heater power control circuit is operated, the bridge circuit receives d.c. power from the heater power control circuit to raise the temperature of the cell 10 until the equality   is satisfied, by the value of the heater resistance RH varying with temperature. At satisfaction of the equality, the bridge circuit nulls when the heater resistance RH has the value RH1. This is observed by the microcontroller which varies the power output of the heater power control circuit to hold the temperature of the lambda cell substantially constant by maintaining the heater resistance at its value RH1 to maintain nullity of the bridge circuit.

Abstract: A pipeline pig suitable for use in cleaning deposits and buildup from a pipeline is also particularly suited for applications wherein the pipeline has a series of bends or even right angle corners.  The pig is suitable for  bidirectional  travel,  having  front  and  rear hemispherical noses.  The pig is constructed in a manner that  facilitates  a greater degree of elongation and deformation than is possible with known pipeline pigs, while still providing the radially outward bias that is required to effectively scrape the sidewalls  of the pipeline.   A cover carries a plurality of metal studs arrayed  about  the  cylindrical  middle  portion,  and encloses an internal core.  The core is formed in a mold from a mixture of resin and ISO,  resulting in a pig having  superior  ability  to  elongate  and  deform,  if needed, while still effectively scraping the sidewalls of the pipeline.

Abstract: Methods and apparatus for providing a secure optical communications link are disclosed. Communications information is encrypted with a security key. An optical beam is then modulated with both the security key and the encrypted communications information, with different modulation schemes being used for each. The dual-modulated optical beam is then transmitted to a receiver. At the receiver, the optical beam is split into first and second optical beams. First and second demodulators are then employed to demodulate the optical beams to recover the encrypted communications information and its data rate, and the security key and its data rate. The encrypted communications information, the security key, and the data rate information are then sent to decryption and timing circuitry which decrypts the encrypted communications information to obtain the original unencrypted communications information.

Filed: 1998-04-02
Granted: 2002-01-15
Abstract: An improved design for a switched reluctance motor is disclosed that keeps the motor cool during operation and thereby improves the performance and reliability of the motor. The improved design employs three centrifugal fans mounted to the motor shaft, which are used to create two independent airflow paths, one of which cools the electronic components of the motor. The improved design also divides the functions performed by a single printed circuit board into two circuit boards, an upper circuit board and a lower circuit board. Another feature of the improved design includes locating the position/speed sensing encoder immediately below one of the centrifugal cooling fans. The disclosed construction provides for increased dissipation of heat that is generated by the motor and its electronic components. In this configuration, the printed circuit boards and other electronic components are located in such a manner that air can be circulated in a path to remove heat from these components.

IPC: G06K19/07
Filed: 1996-12-02
Granted: 2001-09-04
Abstract: Known tags which are capable of receiving and demodulating signals by way of one and the same antenna and by way of one and the same diode, as well as being capable of modulating and transmitting signals, often have a poor efficiency, particularly if the antenna is implemented in the form of a fiat plate. By coupling a high-ohm first terminal of the antenna to the diode, and coupling a low-ohm second terminal to earth by way of an inductive element, there is obtained a tag which has a good efficiency, both regarding the reception and demodulation of signals and regarding the modulation and transmission of signals.

Abstract: A corner piece used in cooperation with retainer strips and exterior siding provides improved protection to a wall of a structure, particularly around rectangular openings in the wall. The corner piece includes a first section extending in a first direction along a first side of the opening and a second section integral with the first section. The second section extends in a direction substantially perpendicular to the first section along a second side of the opening adjacent the first side. The first and second sections form a continuous channel that extends into the retainer strips. A first retainer strip may be received within the first section and the second section of the corner piece may be received within a second retainer strip. As a result, the channel formed by the first retainer strip overlaps a portion of the first section and the channel formed by the second section of the corner piece overlaps a portion of the second retainer strip. Thus, water flowing in the channel formed by the retainer strips and corner piece may flow from a retainer strip, over the corner piece and past another retainer strip with minimal opportunity for the water to flow behind either the corner piece or either of the retainer strips. In addition, the continuous channel formed by the corner piece and retainer strips directs water away from the wall by an angled bottom surface of the channel.

Title: Floating transceiver assignment for cellular radio
Inventor: JEFFRIES ANDREW WILLIAM
IPC: H04W16/28
Filed: 1998-05-01
Granted: 2002-07-02
Abstract: A frequency allocation method for allocating carrier frequencies to a plurality of fixed beams in a cellular radio based transceiver station comprises maintaining a reserve pool of carrier frequencies (1000), such that any available carrier frequency can be allocated to any fixed beam at any one time in order to deal with capacity demands from mobile stations within an area covered by a fixed beam (1002). A frequency allocation algorithm operates such as to allow a plurality of transceivers to float anywhere across a plurality of fixed directional beams. More carrier frequencies can be added to a beam to deal with increased mobile station capacity demand. The occupancy of channels on the carrier frequencies is continuously monitored, and the number of carrier frequencies perbeam is continuously monitored (1001, 1003), with the object of releasing unusedcarrier frequencies to a reserve pool of carrier frequencies (1005), allowing redeployment of unused carrier frequencies to other beams where necessary (1104). Carrier frequencies are periodically "groomed" by assessing the number of vacant channels on the carrier, and reallocating any un-utilized vacant channels to other carrier frequencies. The grooming process can be constrained to operate during natural gaps in speech, to avoid channel degradation.
