Title: Multi-lumen enteral feeding and medicating device
Inventor: GOELZ RICHARD G
IPC: A61M25/14
Filed: 1996-03-21
Abstract: A multi-lumen enteral feeding and medicating device having a gastric tube adapted to be introduced into the interior of a patient's stomach through a stoma. The gastric tube has a balloon to engage and seal against the interior wall of the stomach around the stoma and a locking ring to engage the skin of the patient surrounding the exterior opening of the stoma. A jejunal tube is slidably engaged in the gastric tube for relative longitudinal sliding displacement so that the distal end of the jejunal tube may be threaded through the stomach into the jejunum for introduction of a fluent material through ports adjacent the distal end of the jejunal lumen. A fluid lumen is provided in the gastric tube for applying positive and negative pressure to the interior of the balloon to extend and retract the same and an inlet attachment is provided for accessing the gastric lumen for introducing fluent material into the stomach through the gastric lumen. The jejunal tube passes through the gastric lumen and out through the inlet attachment. A sealing plug is provided to seal the inlet to the gastric lumen at the point where the jejunal tube exits the gastric lumen. The sealing plug operates to anchor the jejunal tube within the gastric lumen at the desired location which positions the distal end of the jejunal tube within the jejunum.

Patent GB-2301251-A (GB)
Title: Distance measurement
Inventor: ITO AKIRA
IPC: G01S7/486
Filed: 1996-05-24
Abstract: A rangefinder for an automatically focusing a camera operates by transmitting 10, 1 a light of beam to an object and receiving 2,3 reflected light. The received signal is converted to a voltage 30, amplified 40,50, integrated 60 and the integrated signal is compared 70 with a threshold Vr. In order to prevent premature triggering by stray electrical signals, the threshold is switched 72 to a higher value when the light beam transmitter is "off' than when it is "on", since the threshold should should not be crossed when the transmitter is "off".

Title: An improved movable ramp assembly
Inventor: TREMBLAY JULES M
IPC: A61G3/06
Filed: 1996-02-26
Abstract: A movable ramp assembly (R) is provided that can be securely stored and safely and reliably operated. The ramp assembly (R) includes a platform (12) that is conveniently stored to travel with a vehicle and deployed in a motion pattern to allow the passage of passengers across the platform (12) into and out of the vehicle. The motion pattern includes an upwardly inclined motion and a downwardly inclined motion which together accommodate most uneven terrain on which the vehicle may be parted. In the disclosed embodiment, the motion pattern of the platform is faciliated by cam guides (54, 56) formed within side beams (18, 20) of a mounting structure and cam followers provided on bracket arms supporting the platform at one end. As the cam followers follow the cam guides (54, 56), the platform is pitched upwardly at an incline and then downwardly at an incline when the platform is deployed from storage. As part of the top panel (14) of the mounting structure, a hinged panel (44) is provided, having multiple functions, In the disclosed embodiment, the hinged panel is substantially horizontal when the platform is stored so as to serve as part of the operating passenger floor with the top panel (14). When the platform is deployed however, the hinged panel (44) is inclined downwardly to about a threshold section of the platform at its free end, thereby bridging the platform and the top panel to form an extended ramp surface.

Title: Motor vehicle door lock sensor arrangement
Inventor: HAGEN FRIEDRICH
IPC: E05B65/20
Filed: 1997-12-15
Abstract: A motor vehicle door lock having a locking system, as well as a closing system acting on the locking system, and having an electronic control and/or monitoring system. The control and/or monitoring system comprises at least one Hall sensor chip which is supplied with current and which comprises a magnetic actuation device and chip electronics. The Hall sensor chip generates first information signals with a high current level I high  and second information signals with a low current level I low . The evaluation electronics unit processes the first and second information signals. The evaluation electronics unit also differentiates between the second information signals which exceed a lower current threshold I SU  and which are also less than an upper current threshold I SO  on the one hand and third information signals which have a current level within the range from zero to I SU  on the other hand. The occurrence of information signals which have a current level within the range from zero to the lower current threshold I SU  is caused by defects in the Hall sensor chip and/or by defects in the conductor paths between the Hall sensor chip and the evaluation electronics unit or by defects in the power supply to the Hall sensor chip.

Title: Colour display
Inventor: SURGUY PAUL WILLIAM HERBERT
IPC: G02F1/137
Filed: 1998-03-27
Abstract: A display comprises a matrix of pixels 11 arranged in rows and columns, each pixel 10 being selectively controllable in terms of its light transmissive condition, and an illumination system, comprising an array 13 of elongate elements which provide light in response to electrical impulses, the elements 4, 5, 6 being arranged side by side to face the matrix. Adjacent elements provide light having a different one of a plurality of colours. The matrix is addressed using a row by row addressing sequence. During part of this sequence, a row of pixels is illuminated with light of a first colour from a first element, whilst a remote row of pixels is illuminated with light of a different colour from a further element. This enables more efficient illumination of the matrix than with conventional colour sequential displays in which all rows are simultaneously illuminated with the same colour.

Title: Borehole logging using gradient echoes
Inventor: PABITRA SEN
IPC: G01R33/44
Filed: 1998-08-28
Abstract: Nuclear magnetic resonance properties of an earth formation traversed by a borehole are measured by generating gradient-echoes. The measurement can be made while drilling or using a wireline tool. The apparatus applies a static magnetic field, B a , in a volume of the formation which polarizes the nuclei of hydrogenous connate fluids within the formation. The apparatus applies a second magnetic field, B b , in a volume of the formation. The magnetic fields B a  and B b  are substantially orthogonal in the volume of the formation. A change in the polarity of the magnetic field, B b , reverses the direction of precession of the nuclei thereby generating a train of gradient-echoes. Each gradient-echo signal is transformed into the frequency domain and the signal frequency is mapped to a radial position in the volume of the formation in order to generate an image of the formation. Various properties of the formation, such as the effective diffusion coefficient of the formation fluid, longitudinal relaxation time, spin-spin relaxation time, and porosity can be estimated from the train of gradient-echoes.

Title: A system fordetermining the accuracy of a circuit assembly process
Inventor: KENT KEVIN
IPC: H05K13/08
Filed: 1998-11-16
Abstract: The accuracy of a circuit assembly process is determined by capturing an image of an assembly formed on a substrate by the circuit assembly process, calculating coverage of the assembly from the image, and comparing the coverage to a threshold. Coverage is a measure of overlap between solder and a pad and/or a lead and a pad, and the process of assembly can be adjusted when it is found to be inaccurate. The step of calculating the coverage is carried out by modelling the components of the assembly as a series of polygons, and determining the points of intersection and enclosure of these polygons.

IPC: G06F9/45
Filed: 1999-03-04
Abstract: A method of translating source code instructions into target code instructions comprises the steps of providing a plurality of templates which implement respective source code instructions without implementing predetermined sub-functions within the source code instructions, selecting the appropriate template for each instruction in an input block of source code instructions and appending this template to an output block of target code instructions, and analysing the source code block to determine the net effect of the non-implemented sub-functions and planting code in the output block to achieve this net effect. The templates may be provided by analysing an existing interpreter to identify sequences that implement individual source code instructions prior to run time. The sub-functions may include updating a program counter, clearing an overflow register or performing address range checks.
