Abstract: The present invention is essentially a method and system for leaving and retrieving messages at specific coordinate way points within a commercial mobile radio service (CMRS) provider network. Users carry or transport interface devices for communicating over the network and are able to record and view messages at specific coordinate locations while traveling in the network. The location of the device is calculated by the device or by the network while the device is powered on and in within the physical boundaries of the network, or through a combination of both. Messages can be made available to network subscribers when their interface devices come within an area centered about a physical coordinate location. Personalized messages can also be left by subscribers at any coordinate point within the boundaries of the network. The invention can also be used to facilitate access of information about an asset when a technician comes within a physical proximity threshold relative to said asset.

Abstract: The invention is a wearable computer system comprised of a transferable core computer module and an enclosure which has been constructed to be instrinsically safe according to Class 1, Divisions 1, 2 or both of the U.S. Electrical Code. According to the system of the present invention, workers may make use of this system in environments in which typical electrical devices may not be used due to the presence of ambient ignitable gases and vapors. The enclosure may also be designed to have the properties of water tightness, air tightness and shock absorbtion.
