A semiconductor device has a first conductive layer formed over a top surface of a substrate. The optical components include a laser source for generating a beam of light, a spectral tuning element and one or more further optical components for directing the beam of light on to the spectral tuning element. The control means is configured to operatively apply a first at least one of the stimulating waveforms of the waveform bank to the brain of the subject through the first accessing means and to assess acceptability within defined limits, as determined by preset criteria, of the subject’s response to the application of the at first least one of the stimulating waveforms. Said aim is achieved by virtue of the fact that, according to the invention, when a radiation parameter is altered, the object is rescanned preferably with the corrected parameter. The transmitter then transmits signal to an electronic receiver and from there to an electronic circuit which transmit signal to a solenoid operatively associated with the shut off gate to open and close the gate. The charging ECU causes the charger to perform additional charging during which charging progresses more slowly than the quick charging, when the state of charge comes closer to full charge than the predetermined state.
