Abstract: A system and related method are provided to diagnose and/or monitor energy efficiency of a building. The system includes temperature sensors positioned inside and outside the building. For various outside temperatures, the temperature differentials over time at the inside sensors are calculated over selectable time periods, whether for the entire building as a whole or for individual rooms. The temperature differential information is then used to determine energy efficiency of the building, including fuel costs/savings and improvements based on weatherization. The system includes standalone temperature monitoring modules or, alternatively, the system includes temperature monitoring modules that do not retain acquired temperature information but instead transmit that information to a networked device, such as an access point for wireless radio frequency signal transmissions.

Abstract: An improved system, both method and apparatus for creating an enhanced virtual reality environment providing an integrated, universal, communication, monitoring and/or control experience, even for those compromised users typically denied such experience, the system providing newly emergent properties not present in the individual modules comprising the system, but for the synergy with each other created through the vehicle of the user's mind, the system having a display subsystem including video and/or audio capability, an r.f. and/or i.f.

Abstract: A wireless phone-line interface provides wireless communications between a modem and a switched telephone network. A wireless phone-line interface has a line interface transceiver coupled to a switched telephone network and a modem transceiver coupled to a modem. The modem may be coupled to computer, multimedia, or other electronic information equipment. The line interface transceiver and modem transceiver exchange wireless signals in reselected channels so that up-link and down-link frequencies transmitted and received by the line interface and modem transceivers are separate and distinct and do not interfere with one another. The cabling previously required between the modem and the switch telephone network is thereby eliminated, allowing easy relocation of the modem with its associated computer equipment to anywhere within the transmission range of the line interface and modem transceivers. The transceivers may be powered by DC-adapted 110 volt AC power.
