Abstract: The timing device is a lifetime monitor for indicating when the usable lifetime of a product has ended or for indicating the timing for regular usage of a product. The timing device has a timing initiator, a power supply in the form of a membrane zinc air battery and a visual or audible indicator. The timing initiator is a tear-off air blocking membrane which lets in air when the tear off film is removed. The timing device is capable of indicating a predetermined passage of time which is substantially independent of ambient temperature.

Abstract: The timing device is used as a lifetime monitor for providing an indication of when the usable lifetime of a product has ended or as a usage monitor for indicating the timing of regular usage of a product. The timing device consists of a main body and a timing initiator (20). The main body consists of a power supply in the form of a membrane zinc air battery and a visual or audible indicator for indicating when the product has been opened for a predetermined duration of time corresponding to the recommended lifetime of the product or alternatively the timing or repeated use of a product such as toothpaste or medicaments. The timing initiator (20) is a tear-off air blocking membrane and the membrane zinc air battery comprises: a porous air input controlling layer (21), which lets in air when the tear off film is removed; a porous air electrode, the anode (22); an interface containing electrolyte (23); a zinc electrode (24); and an outer adhesive film for attaching the timing device to a product package (25).

Abstract: A social networking system and method for entrepreneurs includes a primary forum offering a plurality of multimedia tools and a primary member registration means for registering a plurality of members for access within a primary community. Members include entrepreneur members, investor members and coach members. The primary forum provides access to hyperlinked content for retrieving business information and interacting and communicating among members. The system further comprises a plurality of satellite forums that are linked to, hosted and maintained by the primary forum. Each satellite forum includes the multimedia tools derived from the primary forum so that members on the satellite forum have access to the information on the primary forum. Satellite forums have their own unique URL and is linked to, hosted and maintained by the primary forum and act as meeting places for satellite groups and satellite communities.
