Patent CA-2081065-A1 (CA)
Title: Image signal coding system
Inventor: MURAKAMI TOKUMICHI
IPC: H04N19/129
Filed: 1992-10-21
Abstract: An adaptive blocking coding system selects an effective blocking of an input image signal to be encoded in accordance with the correlation between fields, even if motion is detected between the fields.  The blocking patterns include an individual field blocking, a non-interlace blocking, a split blocking and an inverted split blocking.  Further, the coding system searches for motion from both odd and even fields of a frame for producing a motion compensated prediction signal in order to provide high-efficient coding.

Title: Particulate fabric softening and detergent compositions
Inventor: DOMS JAN R P
IPC: C11D17/04
Filed: 1993-05-06
Abstract: ABSTRACT OF THE DISCLOSURE:           A particulate fabric softening composition and a partic-ulate fabric softening detergent composition are described, both of which include bentonite powder agglomerated into larger particulate bead or granule form with a normally solid co-melt of a penta-erythritol compound (PEC), such as pentaerythritol ditallowate (PEDT), and a nonionic surfactant, such as a condensation product of a mole of a C12-15 fatty alcohol with seven moles of ethylene oxide.  The fabric softening composition described may be added to wash (or rinse water) but preferably is incorporated in a particulate built synthetic organic anionic and/or nonionic detergent composition to produce a fabric softening detergent composition.  The invented detergent compositions are especially suitable for washing laundry in "cold" water, such as water at 40°C. or thereabout, in which the nonionic surfactant increases the dispersibility of the PEC, improves fabric softening activity thereof, in conjunction with the bentonite, and also prevents excessive whitening or chalking of dark colored laundry by the particulate fabric softening composition.  These improved results have been attributed to the nonionic surfactant lowering the co-melt's melting point to about 40°C. or lower, at which temperature the softening composition disperses satisfactorily in the wash water.  Additional advantages of the invention are a bonus effect of the nonionic surfactant in increasing detergency of the detergent composition and wash water, and in allowing a decrease in PEC content of the softening and detergent compositions without loss of softening effect.

IPC: G01J5/52
Filed: 1993-11-30
Abstract: A method and apparatus for non-uniformity compensation for infrared focal plane arrays in an infrared imaging device (10) including a calibration operation and a correction operation. The calibration operation measures the response (24) generated by the detector elements (14) in the focal plane array (16) to a wide range of known levels of infrared radiation (22) produced by a uniform black body under controlled conditions. The responses (24) are then stored as a digital video signal (27) in a look-up table memory(38). The correction operation achieves the near real-time compensation of a second response of the detector element (14) to the level of infrared radiation (22) produced by objects in the field of view surveyed by the imaging device (10) by comparing the second response to the stored digital video signals (27) and interpolates the second response to a corrected digital video output signal (31).

Title: Apparatus and a process for recording photometric data that is positioned in succession or in adjacent fashion on a page-like or strip-like print
Inventor: BERNER MARKUS
IPC: G01N21/55
Filed: 1994-05-11
Abstract: An apparatus for recording photometric data that is positioned in succession or in adjacent fashion on a page-like or strip-like print is equipped with at least one reflectance measuring unit with a reflectance measuring lens for measuring opaque prints (for example, paper test strips for examining the paper developing baths or for control of the basic printer setting). Wavelength dispersion elements positioned in the light path of the reflected light permit the analysis of the measuring fields according to wavelengths and preferably in the three primary colors of red, green, and blue. The apparatus can be equipped with an automatic transport device for the page-like or strip-like prints; the transport device is positioned behind the measuring lens. The prints are inserted into the device through an intake slot which is designed to accommodate prints of different width. On at least one side of the intake slot there is at least one stop for the prints. Each stop is stationary relative to the intake slot for the prints. The reflectance measuring lens and the print seized by the transport device and transported in the longitudinal direction can be moved in the transverse direction, relative to one other. In this manner it is possible to measure adjacent measuring fields without having to reposition the print between individual measurements.
