Abstract: A HVAC device is provided. The device includes at least one environmental sensor, a control processor that compares data from the at least one environmental sensor with a reference value, the processor providing an output indicating the environmental data exceeds the reference value a communication interface coupled to the processor, the communication interface transfers the output of the control processor to a remotely located control panel and an interactive display coupled to the processor, the display depicting environmental data from the at least one environmental sensor for a predetermined time period after activation of the interactive display by a user and a blank screen thereafter.

Abstract: A device for generating controlled vibration in an uncontrolled temperature environment includes a driving circuit that generates a signal having a first frequency and has a temperature-sensitive driving unit, a vibratory element coupled to the driving unit that vibrates at the first frequency according to the generated signal, and a temperature control circuit to control the temperature of the driving unit.

Abstract: A flame detection system includes a plurality of sensors for generating a plurality of respective sensor signals. The plurality of sensors includes a set of discrete optical radiation sensors responsive to flame as well as non-flame emissions. An Artificial Neural Network may be applied in processing the sensor signals to provide an output corresponding to a flame condition.
