Title: Gas mixing system and method
Inventor: SILVIS WILLIAM M
IPC: G01N1/38
Filed: 1999-07-13
Abstract: A mixing system with proportional dilution gas sampling, and associated proportional dilution gas sampling methods are provided. The mixing system includes a mixing portion, a gaseous inlet, a dilution inlet, and a mixture outlet. A flow meter in flow communication with the dilution inlet has an output indicative of the dilution gas flow rate. A dilution sample line in flow communication with the dilution inlet collects samples of the dilution gas. A dilution sample flow controller along the dilution sample line is applicable to vary the dilution sample flow rate through the dilution sample line. Control logic receives the flow meter output, processes the flow meter output, and operates the dilution sample flow controller to vary the dilution sample flow rate. The dilution sample flow rate is varied in response to variations in the dilution gas flow rate such that the dilution sample flow rate tracks a value which is substantially proportional to the dilution gas flow rate.

Title: Methods of setting and retrieving a flow modifier in a pipe
Inventor: DE ALMEIDA ALCINO RESENDE
IPC: B08B9/055
Filed: 2001-01-30
Abstract: A method of setting a flow modifying device (3) in a pipe (1) involves pushing the device (3) using a flexible pig (4) into engagement with a stop device (5) set into the pipe (1). Once the device (3) has contacted the stop device (5) fluid pressure in the pipe (1) forces the flexible pig (4) through the device. The device (3) can also be retrieved by removing the stop device (5), inserting a second pig (34, fig 2b) and allowing the pig to drive the device (3) along the pipe (1, fig 2d). The stop device (5) can be of two types. The first type (fig 3) requires that fluid flow in the pipe (1) is stopped for installation, whilst the second type (fig 4) can be installed whilst fluid is still flowing.

Title: Reduction of column fixed pattern noise in image sensors
Inventor: HENDERSON ROBERT
IPC: H04N5/217
Filed: 2001-08-11
Abstract: Solid state image sensors, and methods of operation thereof, of the type comprising an array of photosensitive pixels arranged in rows and columns and in which pixel data signals are read out from said pixels via column circuits which introduce column fixed pattern noise to said signals. The signals are selectively inverted at the inputs to said column circuits and the inversion is reversed following output from said column circuits. In preferred embodiments, each column circuit includes an analog to digital converter and a digital inverter for inverting digital output from said analog to digital converter. The selective inversion may be applied to alternate rows or groups of rows of said pixel data, and may be applied differently to different frames of said pixel data. These techniques result in column fixed pattern noise being modulated (or dithered) in a manner which makes the noise less apparent to the eye and which facilitates subsequent cancellation of the noise. In certain embodiments the means for selectively inverting the signals includes a chopping circuit in each column.

Title: Aspherical spectacle lens for correcting hereophoria of the eye
Inventor: SHIRAYANAGI MORIYASU
IPC: G01N21/88
Filed: 2001-10-17
Abstract: An aspherical spectacle lens (1) has a prismatic power to correct hereophoria (visual axes being deviated during resting periods) of an eye. The spectacle lens has front (2) and back (3) surfaces, one of which is a rotationally-asymmetrical aspherical surface for correcting the aberrations caused by adding the prismatic power. When the back surface(3) is rotationally-asymmetrical, curvature of an intersection line (7) of a plane containing the normal (Z2) to the rotationally-asymmetrical surface at a framing reference point (4) and the rotationally-asymmetrical surface (3) at the prism base side may be larger than that at the apex side (i.e. in the area marked "R"). The framing reference point is coincident with a pupil position (5) of a user when the spectacle lens is installed on a frame. On the other hand, when the front surface (Fig 3, 12) is rotationally-asymmetrical, the curvature of the intersection line at the prism base side may be smaller than that at the apex side.

Abstract: An image scanner includes a light source 104, calibration strip 116 and array of photosensors 122 which receives light from at least the centre and one end of the source, scattered from the calibration strip whose position is fixed relative to the photosensors. As described, the calibration strip and array 122 are mounted on a scan carriage with the light source 104, together with a second array receiving light scattered from the document 100. The photosensor arrays may each comprise three arrays for sensing R, G, B. Alternatively, there may be two calibration strips (116, 600, Fig 6 not shown) and means for shifting the photosensor arrays so that one array (122) receives light from one calibration strip (116) at one position, whilst the other array (114) receives light from the other strip (600) at the other position. In another embodiment (Fig 7 not shown) an optical wedge (700) is included in the path and its position is adjusted to switch the arrays receiving calibration light. The signals from the calibration strip may be used to adjust the output from the sensors receiving light from the document so as to compensate for variations in light output of the source, so allowing the scanner to be used before the light source is fully warmed up.

Title: Method of inserting additional data into a compressed signal
Inventor: FERRIS GAVIN ROBERT
IPC: G10L19/00
Filed: 2002-02-08
Abstract: The method comprises detecting whether the original information content of a media data portion of a frame in the compressed signal falls in whole or part below a threshold, and, if so, discarding the whole or part of that portion and inserting the additional data into an ancillary portion of the frame to occupy space vacated by the discarded portion. The detection can be effected while the signal is in compressed form and may involve the examination of amplitude data coded as scale factors. The method is applicable to the insertion of data into silent audio frames or blank video frames. In an MPEG implementation, subbands associated with silent frames are rendered digitally silent and then used to carry data such as programme associated data (PAD).

IPC: G08G1/123
Filed: 2001-12-11
Abstract: A central processing station (9) receives information signals indicative of highway traffic and determines a model of actual highway use therefore. A virtual model of efficient highway use is developed from the model of actual highway use and a theoretical model of highway use and instructions are determined to try to alter the actual traffic characteristics in order to try to conform the model of actual highway use to the virtual model of efficient highway use. The instructions are then sent to to selected vehicles on the highway to command them to increase/decrease speed or charge lane in order to more closely conform to a virtual model for efficient vehicular use of the highway. The information signals and the instructions are sent by means of the cellular network using transceiver stations (7 and 8).

Title: Adaptive modulation and coding method
Inventor: AWAD YASSIN ADEN
IPC: H04W28/18
Filed: 2002-07-30
Abstract: An adaptive modulation and coding method comprises selecting (S7) one of a plurality of different available modulation and coding levels to apply to a signal transmitted from a transmitter to a receiver. The selection is based on a comparison between a signal transmission quality («or/Ioc) and one or more threshold values. The or each threshold value is adjusted (S5, S6) when the signal transmission quality is within a predetermined range of that threshold value, and is maintained unchanged (S3) when the signal transmission quality is outside that range. By maintaining the threshold value unchanged when the signal transmission quality is outside the range of that value the adjustments to the threshold value(s) are limited, whilst still enabling the threshold value(s) to take account of prevailing signal transmission conditions. This leads to improved throughput performance, especially under path conditions involving a single dominant path.
