Patent EP-0803521-A1 (EP)
Inventor: SAEKI TAKUYA
IPC: C04B24/28
Filed: 1997-04-22
Abstract: A new block copolymer, which is excellent with regard to abilities such as dispersibility, chelatability, and scale inhibitability, includes a polyalkylene glycol structural unit and a polyglyoxylate structural unit. This block copolymer, for example, can be produced by carrying out a polymerization reaction between a polyalkylene glycol and a glyoxylic acid-based monomer in the presence of a catalyst in a polymerization reaction system having a water content of about 30 mol % or less relative to the polyalkylene glycol, and used as a cement dispersant, pigment dispersant, water-treating agent, or detergent builder.

Abstract: A mobile telephone system and method wherein the system has a base station (7) for receiving data bursts during consecutive frames, each frame being of predetermined time duration and being divided into a plurality of slots of predetermined time duration. The base station has an antenna (5), base station electronics (11) and preprocessing circuitry disposed between the base station antenna and the base station electronics. Delay circuitry (9) is coupled between the base station preprocessing circuitry and the base station electronics to provide the complement of a total time delay to the data bursts through the preprocessing circuitry and the delay circuitry such that the total delay through said preprocessing circuitry plus said delay circuitry is equal to an integral number of the predetermined time duration of a frame. The time delay of the preprocessing circuitry can be fixed, in which case the time delay of the delay circuitry is fixed. The time delay of the preprocessing circuitry can also be variable, in which case the time delay of the delay circuitry is variable. In the case of variable delay, the delay circuitry will include circuitry to monitor the time delay provided by the preprocessing circuitry and adjust the delay in the delay circuit in accordance with the monitored delay in the preprocessing circuitry.

Abstract: A system and process for true multi-image alignment that does not rely on the measurements of a reference image being distortion free. For instance, lens distortion is a common imaging phenomenon. When lens distortion is present, none of the images can be assumed to be ideal. In an embodiment of the invention, all the images are modeled as intensity measurements represented in their respective coordinate system, each of which is related to a reference coordinate system through an interior camera transformation and and an exterior view transformation. Motion parameters (16, 17, 18) determined in accordance with an embodiment of the invention dictate the position of the input frames (11, 12, 13) within the reference frame (15). A reference coordinate system is used, but not a reference image. Motion parameters (16, 17, 18) are computed to warp all input images to a virtual image mosaic in the reference coordinate system of the reference frame (15). Each pixel in the virtual image mosaic may be predicted by intensities at corresponding pixel positions from more than one image. The error measure, which is the sum of the variances of predicted pixel intensities at each pixel location summed over the virtual image mosaic, is minimized. The embodiment of the invention advantageously maximally uses information present in all images.
