  • Patent number: 5602092
    Abstract: Concentrated, structured liquid detergent compositions in the form of lamellar surfactant droplets dispersed in an aqueous electrolytic continuous phase comprises a mixture of:a) from about 10 to 45% by weight of surfactant;b) at least one detergent builder;c) from about 0.01 to about 5% by weight of a deflocculating polymer composition containing polymer chains of the structure P-QR, wherein P represents a polymer chain segment of a hydrophilic polymer, and QR represents a hydrophobic end-cap group wherein R is an organic hydrophobic radical containing from about 4 to 28 carbon atoms, and Q is selected from the group consisting of O, S, SO, SO.sub.

  • Patent number: 5579472
    Abstract: A system and methods are provided for displaying and processing communications via a variety of communications media using a personal computer. Messages received either wirelessly, for example, wireless e-mail, or over telephone wireline, such as voice mail or facsimile, are segregated and presented for review by the subscriber according to whether the originator is within a select group of routinely contacted individuals and also by type of media. The system includes a graphical user interface to provide an intuitive and efficient message processing capability. In alternative embodiments the apparatus and methods are self-documenting and facilitate communication to the system manufacturer.

  • Patent number: 4988852
    Abstract: A system for finding and reading a bar code, arbitrarily located on a document, working from an electronic image of the document represented by a pixel array such as generated by a document scanner. A one-dimensional texture analysis is performed in the scanning direction by defining a pattern of test segments and searching for characteristic ranges of transistions within those test segments. If a horizontal test segment pattern fails to locate a bar code region, a test segment pattern skewed with respect to the horizontal is applied. If test patterns skewed with respect to the horizontal fail to locate a bar code region, then a state-transition analysis is applied in the direction perpendicular to the scan direction and in directions skewed with respect to that perpendicular to search for a terminal symbol characterizing the bar code.
