Abstract: A dispenser for dispensing a viscous liquid in a pliable container includes a housing having at least one sidewall and a bottom portion to define an interior enclosure for receiving the pliable container. The bottom portion has an opening configured to align with at least a portion of an opening of the pliable container. A compression assembly includes a compression member moveably positioned within the enclosure and a handle extending externally from the housing and coupled to the compression member to cause movement of the compression member about an axis, wherein manual movement of the handle moves the compression member about the axis and provides a lateral force on the pliable container such that the pliable container is compressed by the compression member and forces the viscous liquid to flow from the opening of the pliable container.

Abstract: A system for analyzing pressure and/or temperature indicating material has an input for receiving a monochrome color density image captured from a pressure and/or temperature indicating material, the image being captured alongside a calibration target against a contrast sheet. A processing module is configured to receive the captured image of the indicating material and the calibration target and to generate a pseudo colored spectrum map by converting the monochrome color density image into a corresponding multi color map where the different colors on the map correspond to different color densities on the monochrome color density image. The processing module is configured to compare the captured colored calibration target against a stored reference image and to adjust the output pseudo colored spectrum map to account for environmental factors that are present during the capture of the monochrome color density image.

Abstract: A trigger sprayer is provided with a passive venting system of simplified and inexpensive construction. A gas permeable, liquid impermeable membrane is positioned over a vent opening in the trigger sprayer housing and prevents the leakage of liquid from a container attached to the trigger sprayer, while allowing the venting of air from the exterior of the trigger sprayer to the container interior. The membrane is secured to a vent opening surface of the sprayer housing that is surrounded by a vent side wall that protects the vent membrane.

Abstract: A venting system of a manually operated trigger sprayer vents the interior of a liquid container connected to the trigger sprayer. The trigger sprayer is provided with a vent chamber that surrounds the pump chamber, and a vent piston that surrounds the pump piston. The vent piston is received in the vent chamber for reciprocating movements with the pump piston in the pump chamber. The reciprocating movement of the vent piston alternatively opens the vent chamber to the exterior environment of the trigger sprayer and thereby vents the interior of the liquid container connected to the trigger sprayer, and closes the vent chamber thereby sealing the interior of the liquid container from the exterior environment.

Abstract: A hand operated liquid dispenser has a simplified, in-line construction that reduces the number of component parts of the dispenser and thereby reduces the dispenser's manufacturing costs. The in-line construction of the liquid dispenser coaxially aligns a liquid discharge orifice, a liquid discharge passage, and a pump chamber of the dispenser. The construction provides a compact liquid dispenser that can be easily held in one hand by a user and manipulated by the fingers of the user's hand to pump liquid from a bottle attached to the liquid dispenser and dispense the liquid in a variety of different discharge patterns.

Abstract: A system and method for teaching proper hand positioning for using a keyboard. The system includes not allowing a lesson for learning to operate the keyboard to begin until home keys are depressed simultaneously. Additionally, the lesson will be interrupted periodically and will not continue until the home keys are depressed simultaneously.

Abstract: A nozzle assembly including a nozzle member, a cap member, a spinner and a foam tube. The cap member is rotationally mounted on the nozzle member and may be rotated from an “off-position” to a “foam-position” with continued rotation bringing the cap member to a “spray-position” and then to a second “foam-position” and then to the “off-position.” Rotation of the cap member drives foam tube from a retracted position to an extended position extending forward of the nozzle member when the cap member is in the “foam-position.” The spinner rotates to atomize liquid flowing through the assembly.

Abstract: A method for managing marker entities within a document data stream independently of the content of the data stream. The method provides consistent specification and independent processing of marker entities which may include both text and non-text data and which may be associated physically and/or logically with data stream content at the document or lower order entity level. A define marker structure control is utilized within the data stream to specify in a data type independent fashion the physical structure and content of a marker entity as well as defining any desired relationship of a marker entity with another entity within the data stream. A map marker control is then utilized to control the position within a presentation area where the marker entity is to be imaged.

Abstract: A method and system are disclosed which permits the self modification of data stream constructs by the utilization of one or more macro definitions, each of which includes a plurality of parameters, at least one of which is modifiable. A modify parameter structured field is included within a selected macro definition and identifies a particular parameter within the macro definition which may be modified. Subsequent invocation of the macro definition may include selective identification of a parameter to be modified. If the identified parameter has been specified as modifiable by the macro definition, the parameter is modified and the macro definition is thereby altered. In this manner the present method permits the utilization of a single macro definition by multiple processes within a data stream.

Abstract: A method is disclosed for controlling the presentation of nested overlays on a display medium. An overlay function resource is provided which includes its own environment specification which is independent of the space and data environment specifications. Mixing attributes are associated with each overlay and are utilized to determine which overlay space and data are to take precedence and be visible when the overlayed spaces are combined and imaged on a display medium. In a preferred mode of the present invention, the foreground and background of each overlay are separately controlled by the mixing attributes which define the mixing rules for the layered presentation of multiple overlays. Additionally, the order of precedence for displaying multiple overlays may be selectively or varied to provide multiple displays and to permit an individual overlay to be repetitively utilized.

Abstract: A system represents a variable construct within a structured data stream. Structured data streams typically include a plurality of components, each component having multiple parameters therein. A trigger or other flag element within the data stream is utilized to provide a link or reference to a variable construct definition which has been created by the data stream originator or an independent end user. The variable construct definition is then utilized to determine previously nonexistent data which may then be utilized to process at least a portion of the data stream. In this manner, variable data within a structured data stream may be processed by linking the variable data to a non-variable construct within the data stream.
