Abstract: A method for measuring efficiency improvement in a heating system. The method includes the following steps: temperature sensors sense an outflow temperature. A controller records the temperature and a call time at a thermostat burner call. Software calculates a percentage of the reduction of fuel consumption, that the efficiency improvement saves. A display displays the percentage saved.

Abstract: Compounds of Formula I are provided. In which the variables are as described herein. Such compounds may be used to modulate CB1 activity in vivo or in vitro, and are particularly useful in the treatment of conditions responsive to CB1 modulation in humans, domesticated companion animals and livestock animals, including appetite disorders, obesity and addictive disorders. Pharmaceutical compositions and methods for using them to treat such disorders are provided, as are methods for using such ligands for receptor localization studies and various in vitro assays.

Abstract: A method and apparatus of regulating cycles of a burner in a forced air heating system. A control unit uses a sensor at an output of a heat exchanger to make measurements of a temperature of air output from the heat exchanger. The control unit observes temperature measurements, after the burner has turned on. It initializes a confirmation interval when two consecutive temperature measurements are the same. If the temperature is the same at an end of the confirmation interval. The invention interrupts firing of the burner for an interrupt interval. The interrupt interval is insufficient to allow the heat exchanger to cool below a temperature useful for heating below which the circulation fan would shut off.

Abstract: To regulate a cooling system operation, a value from an energy value sensor such as a thermostat or pressuretrol is sensed and, if the value warrants a call for compressor operation, the call is made. The last compressor off-call-time is stored in memory. If the off-call-time is less than a short-cycle interval, the compressor is delayed to allow substantial compressor pressure equalization. Compressor operation is delayed further for a percentage of the off-call-time. compressor on-time is also measured and, if on for a substantial interval, the compressor is given a short rest. Improved efficiency results.

Abstract: A method and apparatus for improving heating system efficiency. An electronic circuit senses a firing signal from a boiler energy value sensor such as a thermostat or pressuretrol. The circuit prevents the boiler energy value sensor from firing the burner, while the circuit senses an energy value of the outflow line at the boiler. The circuit monitors the outflow energy value and records the outflow energy value at a first time of the firing signal. The circuit then continually monitors the outflow energy until it detects an energy drop from the initial outflow energy value. The circuit responds to the energy drop by firing the burner. The invention self adaptively responds to present thermal load, reduces the number of on-off cycles, increases each burner run time while reducing total run time, improves fuel consumption, and reduces air pollution.
