Abstract: A method for remote energy consumption system retrofit identification for a facility includes receiving energy consumption data associated with the facility, generating facility data associated with the facility, and receiving external variable data associated with the facility corresponding to the energy consumption data. The method also includes generating a first energy consumption model based on the facility data, the energy consumption data, and the external variable data. The method also includes generating a second energy consumption model based on the facility data and the external variable data. The method further includes determining energy consumption efficiency for the facility using the first and second energy consumption models and identifying a retrofit of an energy consumption system of the facility based on the energy consumption efficiency.

Abstract: A system for remote energy consumption system identification of a facility includes a processor, and a memory coupled to the processor. The system also includes an energy consumption database accessible by the processor. The energy consumption database includes aggregated energy consumption data associated with the facility. The system also includes a facility database accessible by the processor. The facility database includes facility data associated with the facility. The system further includes an external variable database accessible by the processor. The external variable database includes external variable data corresponding to the energy consumption data. The system also includes an analysis engine residing in the memory and executable by the processor.

Abstract: A protection system for a scroll machine provides temperature, mis-wiring and vibrational protection for the scroll machine. The vibrational protection comprises a vibration sensor which is integrated on the circuit board of the protection system. The vibration sensor, in conjunction with at least one timer, monitors the vibrations of the scroll machine and will shut down the machine when excess vibrations are sensed over a prespecified period of time. The temperature system monitors operating temperature conditions and the mis-wiring system monitors the power supplied to the compressor. Once an undesirable characteristic is identified, the operation of the scroll machine is stopped. These protection systems are integrated into a single module which identifies the reason of shutting off the scroll machine in order to simplify repairs needed.

Abstract: An add/shed load controller which will add/shed or increase/decrease the electrical usage of a load. A maximum decrease limit may be set for analog loads to insure that comfort is not overly affected due to load usage reductions.

Abstract: There is disclosed an add/shed system and method for adding and shedding loads to maintain the power consumption of a building below the predetermined level. The system includes a plurality of loads and measures the present total power consumption of the building. Selected ones of the loads are reactively shed in response responsive to the measured total power consumption of the building to maintain the present power consumption of the building below the predetermined level. The anticipated future increase or decrease in power consumption of the building is determined and selected ones of the loads are added or shed in response responsive to the measured total power consumption of the building and the anticipated future increase or decrease in power consumption of the building for continuously maintaining the power consumption of the building below the predetermined level.

Abstract: There is disclosed a portable computer system including a computer, a power supply for the computer and a plate assembly which provides a support for the power supply external to the computer and a foot for disposing the computer in a desired position. The plate assembly includes a first plate to which the computer is attached, a second plate to which the power supply is attached and a hinge coupling the first and second plates together. The hinge allows the plates to be in substantial planar alignment or at an angle to each other to permit the second plate to function as a foot for the computer.

Abstract: In a contention polling arrangement wherein polling messages are transmitted by a central controller for simultaneously polling a group of remote stations, the polling message contains an address which defines the entire range of remote stations to be polled and the remote stations will respond if their addresses fall between the address contained in the polling message and an address resulting from converting any trailing 0's of the address in the polling message to 1's.

Abstract: A system for leveling energy consumption of loads being controlled by a duty cycle routine, the loads having on times and off times within a predetermined period of time established by the duty cycle routine, the system having a plurality of loads, a communication channel connected to each of the loads, and a controller connected to the communication channel, the controller determining a gap time during which no load is off, the gap time being a function of the period of time, the sum of all of the off times for each of the loads, and the number of loads, the controller scheduling the loads to be off, the off times being distributed over the period of time with a gap time existing between adjacent off times.

Abstract: An adaptive optimum start/stop controller for controlling an air treatment apparatus at a reduced energy consuming level during periods of non-occupancy of a building and for energizing the air treatment apparatus before occupancy so that the building is comfortable by occupancy, the controller including a temperature sensor for sensing space temperature within the building, a controller responsive to the temperature sensor and to real time for determining optimum start/stop times so that the building is controlled at energy conservation levels during non-occupancy and comfortable levels during occupancy, the controller adjusting the optimum start/stop times based upon the accuracy of prior start/stop times, and a communication channel for connecting the controller to the air treatment apparatus.

Abstract: An add/shed system for adding/shedding loads to maintain a building's power consumption below a predetermined level, each load being assigned to one of the multiple types of add/shed routines, each routine controlling the adding/shedding of the loads in a different sequence.
