Abstract: A custom-formable knee immobilizer product for being custom-formed to the shape of a knee while flexible and upon hardening providing a rigid, knee-supporting custom fit. The knee immobilizer product includes an outer container formed of moisture-impervious material and a plurality of elongate knee splint segments positioned in the container in substantially moisture-free conditions and sealed therein against entry of moisture until use. Each of the knee splints includes an elongate substrate, a reactive system impregnated into or coated onto the substrate. The system remains stable when maintained in substantially moisture-free conditions and hardens upon exposure to moisture to form a rigid, self supporting structure. A flexible protective outer cover is positioned over the substrate along its length to enclose the substrate. The substrate and outer cover thus form a unitary structure for being molded while flexible to an aspect of the knee and adjacent thigh and calf portions of the leg. A bandage is provided for being positioned on and held in a closely-conforming configuration around the knee and adjacent thigh and calf portions of the leg. Splint supports cooperate with the splints and the bandage for maitaining the plurality of splints on the bandage in closely conforming position in vertically spaced-apart relation around the knee for substantially immobilizing the knee in a predetermined recovery position.

Title: Method and system for building an internet replica of a city using network access points
Inventor: LIU IAN Y W
IPC: G06Q30/06
Filed: 2003-06-20
Abstract: A method and system for building a virtual city over computer networks using network access points. The network replicates a city's function and serves as an alternate dimension for a city's growth and economic development. Each access point serves as an entrance point for local users and business entities to share and interact in their local area over the Internet, as if they would in real life. Each user or business entity using the network has a virtual presence in the website network, serving either as a virtual business entity or a virtual citizen; furthermore, governors are assigned for each local access point as module developers in order to further replicate a city's function.  Successfully implemented modules are adopted throughout the network like a government-adopted policy. This Internet based city replica provides an alternate means for civilization and economic development, a virtual ground to conduct a city's function and interactions. The network also promotes social interaction and community awareness between local businesses and residences in a mass society.
