Abstract: An elastic physiological patch includes a patch assembly and an implant assembly. The patch assembly includes an electronic device, and a soft patch body defining a chamber for receiving the electronic device. The implant assembly is mountable to the electronic device and includes an implant which is capable of being driven to partially pass through the patch body and which is adapted to be implanted in the skin of a subject. The implant and the patch body cooperatively seal the chamber.

Abstract: Real-time interactivity is provided across a shared multiple-participant three-dimensional (3D) virtual-reality environment on the World Wide Web (WWW), with the purpose of allowing a plurality of users to participate in a 3D virtual-reality world where the participants can share information and interact with each other substantially in real time. Through the use of a Client-Information Manager Program (CIMP) module, which is connected via a Common Gateway Interface (CGI) module to the WWW server, each user is able to interactively communicate with any of the other users participating together in the same 3D virtual-reality world. The shared multiple-participant 3D virtual-reality environment utilizes modified Protocol Data Unit (PDU) formats based on the Distributive tive Interactive Simulation (DIS) protocol for data communication among the WWW server and the various client sites.
