Abstract:

A memory packaging scheme for high speed computer systems includes, several memory module sockets mounted to a printed circuit board and interconnected by a common set of address, data and control transmission lines within the printed circuit board. The transmission lines are interrupted at each connector. Cooperating memory modules, such as SIMM memory modules are installed in sequence into one or more of the module sockets in accordance with the requirements of the computer system. Installation of a memory module into a memory socket closes the open circuits for each one of the transmission lines at the memory socket, extending the uninterrupted length of the transmission lines to the next memory socket in the sequence. The memory socket and cooperating memory module design thus provides for sizing of the memory board transmission line lengths to accommodate the number of memory modules installed into memory board sockets, thereby eliminating undesirable transmission line effects from occurring within the printed circuit board transmission lines connecting the memory modules.

Abstract:

A system, method and apparatus for remote control of a thermostat by a network-based server, when the thermostat is not connected to a local or wide-area network. A network-based server calculates a modified temperature profile for a thermostat based on a utility's time-of-use pricing and/or weather forecasts. After the server has calculated the modified temperature profile, it is provided to a mobile device via a wide-area network, and the mobile device provides the modified temperature profile directly to the thermostat when the mobile device is within range of the thermostat.
