Title: Passive surface wave sensor which can be wirelessly interrogated
Inventor: REINDL LEONHARD
IPC: G01S13/02
Filed: 1992-12-21
Granted: 2004-05-18
Abstract: Passive surface wave sensor for measured value determination, in which the measured value is transmitted by radio from the remote measuring location to an interrogation device (1), which transmits energy by radio to the sensor element (5, 15) as an interrogation pulse.      This surface wave sensor according to the invention is suitable for contactless measured value acquisition, a surface wave arrangement being the sensor element and a surface wave reference element being provided for phase discrimination and/or propagation time measurement. As a further development, a sensor operated with chirped transmitting signals and having chirped reflectors is specified, in which there is in the arrangement a reference function in place of the reference element. A sensor designed such that it has a chirped function has the characteristics of an imminently temperature-compensated sensor (Figures 12, 13) for the measuring of other physical or similar variables.
Patent CA-2128578-C (CA)
Inventor: RAO RAMANA B
IPC: G06F17/30

Abstract: A method is disclosed for operating a processor-controlled system to produce from a first table image, upon receipt of an image display request signal from a signal source, a second table image including focal and context cell regions having output region sizes different from the regions sizes of the corresponding cells in the first table image. The output region size of each focal cell region is determined according to a "degree of interest" (DOI) function for each dimension of the table image that represents the level of interest of each cell region in that dimension. A predetermined cell size is allocated to focal cell regions, and the remaining available output space is allocated to the cell sizes of non-focal cell regions.      Image definition data defining the second table image is then produced.    For each focal cell region in the second table image, the source data value of a respectively paired source data item in an underlying n-dimensional (nD) information data array is obtained. Image definition data defining the image representation of the source data value is then produced for display in the respective focal cell region. The second table image having focal cell regions showing source data values therein is then displayed in the display area of a system display device. In another aspect of the method of the invention, graphical display objects indirectly, or graphically, representing the data values in the underlying data array are included in the non-focal cell regions. The graphical display object for each non-focal cell region is determined by a cell presentation type selected using the data type of the respectively paired source data item. Image definition data defining the graphical display object for each non-focal cell is provided to a system display device for display in the second table image. The underlying data in the nD data array is thus directly, or symbolically, represented in the focal cell regions and graphically, or indirectly, represented in the non-focal cell regions, facilitating both direct observation and interaction with actual data values and the visual inspection and identification of patterns and trends in the data. In addition, for very large table images that do not fit in a standard sized display area, the combined features of focal cell regions and indirect representation of the data occupies substantially less space in the display area and pemits a very large table to be entirely represented in one image, while still providing direct access to data values of particular interest. A sophisticated user interface permits a system user to fluidly adjust the focal region location and to perform table manipulation functions, such as reordering rows and column, sorting rows or columns, and deriving new rows or column, in order to further reveal data trends and patterns in the graphical representations.

Abstract: For quantization of subframe feature vectors representative of subframes identified by subframe indexes in each frame of a time sequential signal, such as an audio or a video signal, a first feature vector of a first subframe of a current frame is extracted with additional extraction of a second feature vector of a second subframe of the current frame and is quantized by a frame vector quantizer unit into a quantized frame vector for the current frame.  Using a quantized frame vector for a previous frame and referring to interpolation coefficient vectors, an interpolator interpolates an interpolated feature vector for the current frame.  An error vector is calculated between the interpolated and the second feature vectors and is quantized by an error vector quantizer unit into a quantized error vector.  The subframe feature vectors are quantized by using the subframe indexes, the quantized frame vectors, the interpolated feature vector, and the quantized error vector.  Preferably, the interpolation coefficient vectors are adjusted according to a mode decided for the current frame by its subframes.

Abstract: A fitting (10) for attachment to a tube (12) by swaging comprises a cylindrical sleeve (16) having a tapered outer surface (30) and an inner surface (20) for receiving the tube (12). A cylindrical swaging ring (22) having a tapered inner surface (50) engages the tapered outer surface (30) of the sleeve (16) such that axial movement of the ring (22) in a forward direction with respect to sleeve (16) causes the ring (22) to apply a radial force to the sleeve (16) to swage it to the tube (12). The swaging ring (22) is locked onto the sleeve (16) both before and after swaging by one or more protrusions (66, 76) on the outer surface of the sleeve (16) which cooperatively engage an annular groove (78) in the swaging ring (22). The location of the protrusions (66, 76) and groove in relation to the tapered surfaces (50, 30) of the swaging ring (22) and sleeve (16) is especially configured to provide smooth axial loading during swaging and increase tube (12) retention capabilities at the conclusion of the swaging operation.
