Abstract: A system and method for transmitting and displaying information in a television distribution system (10), or the like, transmits information that is targeted to a viewer matching particular demographic data. The results of a viewer completed demographic survey are used to generate a database known as a bit mask (30) that is made up of the viewer's demographic data. The bit mask (30) is used to control the particular advertising or other related information that is received by each system viewer. In a first technique, the transmission signal carrying the program or advertisement displayed to all viewers is embedded with one or more codes. These codes are compared to the bit mask to determine whether the viewer fits the desired demographic profile, and should be provided with additional information. In a second technique, multiple ads for demographic selective receipt by each viewer are simultaneously transmitted, and are automatically selected for viewing, depending on the viewer's stored demographic data.

Abstract: A valve for a pressurized container includes a valve housing having a central bore and a port in the for connection of a nozzle. Preferably, the valve has a unidirectional stepped valve housing. In the housing is a central bore that includes an upper portion, lower portion and a middle portion. The lower portion is narrower than the middle portion which in turn is narrower than the upper portion. The port is provided in the middle portion of said housing to facilitate connection of a nozzle to the valve. The valve has a t-stem with a lower end having a key-way and a cavity for receiving the upper portion of the valve seat. The valve seat provides the primary valve seal when the valve is closed. The upper portion of the valve seat has a geometry for engaging the t-stem to provide a locked assembly.

Abstract: A non-refillable valve for a pressurized container is provided and includes a valve housing having a central bore, a port in the housing to facilitate connection of a nozzle to the housing, a t-stem and a valve seat that provide the primary valve seal when the valve is closed; and a blocking element in the central bore, the blocking element including a check body with raised and recessed portions wherein the raised portions permit centering of the check body in the central bore and wherein the recessed portions permit fluid flow in the central bore past the check body.

It has a lower portion that is shaped to provide the primary valve seal in cooperation with the valve housing. The upper portion of the valve seat has a geometry for engaging the t-stem to provide a locked assembly.

Abstract: Navigation techniques enable Internet web pages and other image frames to be navigated using a conventional keyboard or a television remote control, for example. In a first technique, a guide mapping application links objects in the various frames contained in an accessed web page so that when a user actuates a directional button on a remote control or a keyboard, the guide mapping application navigates the user to an object in the present frame or in another frame to which a currently selected object is linked. The guide mapping application also employs “edge of frame” indicators in those objects which are located on an edge of a frame. When an “edge of frame” indicator is detected, the application searches for and locates the appropriate adjacent frame, as well as the object within the adjacent frame that is located in the closest proximity to the object containing the “edge of frame” indicator, and then navigates the user to that object.
