摘要:
The present invention generally teaches systems and methods for creating appliance signatures based upon whole house composite load profiles. Methods may includes steps such as identifying primitive elements including transients and absolute steady state levels; clustering the primitive elements along multiple dimensions to form impulses; combining impulses to form simple bundles; combining simple bundles with each other or impulses to form complex bundles; and determining specific appliance signatures that substantially match the complex bundles. Methods may also include steps such as determining transitions within the whole house composite load profile; determining household specific appliance state machines for each appliance in the household; and disaggregating the whole house composite load profile into individual appliance energy loads by assigning the determined transitions to the determined household specific appliance state machines.

摘要:
An apparatus for switch ON/OFF impulse detection includes an impulse detector (210) and a microcontroller (240). The microcontroller is coupled in signal communication to the impulse detector (210). The impulse detector (210) is operative to receive an impulse response from an antenna (220). The impulse detector (210) is operative to provide one of a single alert signal and a plurality of alert signals for the microcontroller (240) in response to the impulse response. The impulse response includes one of a single impulse waveform and a plurality of impulse waveforms. The impulse detector (210) generates the single alert signal when the impulse response includes the single impulse waveform. The impulse detector (210) generates the plurality of alert signals when the impulse response includes respective ones of the plurality of impulse waveforms. The microcontroller (240) is operative to determine a nature of the impulse response. The nature is determined as a switch-ON response when the single alert signal is received. The nature is determined as a switch-OFF response when the plurality of alert signals are received.
