An embodiment of an apparatus includes a component determiner configured to determine a component of a first signal, and an interpolator configured to interpolate a portion of a second signal in response to the component of the first signal. A support member is connected to the one-sided end of the screw member while centrally bearing a support bar protruded opposite to the screw member. The invention also refers to a device for the detection of halitosis, which comprises said sensor located inside a transparent tube. The method is characterized by measuring a voltage between the first and second electron conducting layers during a period of the open circuit and controlling a pulse parameter of the voltage pulses dependent on the measured voltage, where the pulse parameter is one of pulse duration and pulse voltage. The method comprises creating an agreement between a consumer and an entity financing renewable energy CPE, wherein creating the agreement includes creating a provision that allows the entity to control power at the consumer premises if a default of the agreement by the consumer occurs.
