Abstract: An image signal processor for use in an imaging system. Each field of an input image signal is stored in a memory. If the picture blurring is not within a predetermined range, a zoom controller disables an optical zoom-in operation and determines the size of a reduced-size readout frame such that the picture blurring is just fit in a predetermined range. On receiving the size, an address genetator generates addresses to cause the pixels to be read out of the reduced-size readout frame, in the memory, which is located at a position shifted from the center of the field by the PV vector and which has the reduced size. In response to receiving the size of the reduced-size readout frame, the interpolator interpolates the read out pixels such that the read out pixels of the reduced-size are magnified up to the predetermined output size.

Granted: 2005-08-16
Abstract: Apparatus for synchronizing a reference clock signal received from a host system with an A/D converter clock signal generated in a data acquisition pod. The pod includes a decoder responsive to communication received from the host for extracting a host reference signal, and a clock signal source for developing an A/D reference clock signal having a frequency that is different from the frequency of the host reference signal.

Abstract: The invention relates particularly to sensing devices and techniques which may be used to provide measurement data to aid an inertial navigation system, or attitude and heading reference system, and so bound the growth of errors which increase with time in such systems when operating autonomously. In one aspect, the invention relates to a method of determining the path length along a borehole from a known reference point to a probe or tool which progresses through a drillpipe or tubular string, to provide data to aid an inertial navigation system. A sensing device 15 is used to detect joints 11 between sections of drillpipe or tubular string within the borehole and the path length is determined from the number of joints detected and a known length of each section of drillpipe or tubular string. In another aspect, a flow measuring device, such as an impeller, is used to measure the velocity of the probe or tool through the drillpipe or tubular string. In another aspect the invention relates to a method of determining the velocity of a probe or a tool moving through a drillpipe or tubular string to provide data to aid an inertial navigation system. Two sensing devices, which are spaced apart by a known distance on the probe or tool, are used to detect one or more positions within a drillpipe or tubular string, and the velocity of the probe or tool is determined from the elapsed time between each sensor detection of the or each position and the distance between the sensors.

Abstract: This invention discloses an adjustable, relatively small phase-shiftable network for an antenna array, which can be incorporated into a PCB distribution network.      The network comprises a PCB distribution element (A) comprising a planar dielectric circuit board (2) supporting a pattern of conductive tracks (3).  The conductive tracks and the dielectric circuit board form a transmission line network which splits a signal applied to a signal input terminal (I) into three paths that terminate respectively in three terminals (T, B and C) for feeding the input signal to Top (T), Bottom (B) and Centre (C) sections of a antenna array. The distribution element (A) is supported in a spaced relationship with a conductive ground plane (B). A moveable planar dielectric element (C) having a series of teeth (4, 5) along opposite edges, is slidably mounted over the top surface of the distribution element (A). The moveable dielectric element (C) is supported in a slidable manner by two rods (6, 7) attached to the ground plane (B). By moving the dielectric element, the phases in the top and bottom sections of the antenna array are changed in opposite directions so that the phase shift in one section is increased and the other section is decreased, which causes the radiating beam to tilt.

Filed: 1998-02-25
Granted: 2010-11-16
Abstract: Disclosed and claimed are vectors having enhanced expression and methods for making and using them. Enhancement of expression is from substantially co-temporal expression of at least one first nucleic acid molecule and at least one second nucleic acid molecule. The second nucleic acid molecule encodes a translation factor. The contemporaneous expression can be from operably linking the first and second nucleic molecules to a single promoter, or from operably linking the first nucleic acid molecule to a first promoter and the second nucleic molecule to a second promoter wherein the first and second promoters function substantially contemporaneously. Thus, the first and second nucleic acid molecules can be at the same locus in the vector or at different loci. The second nucleic acid molecule can encode one translation factor or more than one translation factor. The translation factor can be a K3L open reading frame, an E3L open reading frame, a VAI RNA, and EBER RNA, a sigma 3 open reading frame, a TRBP open reading frame, or combinations thereof. The vector can be a poxvirus such as an attenuated poxvirus; for instance, a NYVAC vaccinia virus or an ALVAC canarypox virus.

Abstract: A computerized method and apparatus are disclosed for analyzing numerical data pertaining to a sample assay comprising at least one biological or chemical sample. The data include a set of data pertaining to each respective sample, with each set of data including a plurality of values each representing a condition of the sample at a given time. The method and apparatus assign a respective numerical value to each of the data values, mathematically combine the numerical values to generate a total value, compare the total value to a threshold value, and control the system to indicate whether the sample has a predetermined characteristic based on a result of the comparison. Prior to calculation of the sample value, filtering, normalizing and other correcting operations can be performed on the data to correct anomalous values in the data which could adversely affect the accuracy of the results. The method and apparatus perform the described functions by representing the data values as points on a graph having a vertical axis representing the magnitudes of the values and a horizontal axis representing a period of time during which readings of the sample were taken to obtain the data values, identifying points on the graph having an anomalous characteristic, and correcting the anomalous points to produce a corrected plot of points on the graph, with each of the points of the corrected plot representing a magnitude of a corresponding one of the values. An area value is then calculated which represents an approximate area between at least a portion of the corrected plot of points on the graph and the horizontal axis. The area value is compared to a threshold value to determine whether a certain condition exists in the sample to which the set of data pertains.
