专利汇可以提供Biopotential digital controller for music and video专利检索,专利查询,专利分析的服务。并且PURPOSE: To generate data which controls generation of a tone by providing a means which senses a biopotential signal in real time, and a means which receives the biopotential to map it to a MIDI(Musical Interinstrument Digital Interface) code in real time.
CONSTITUTION: A transducer senses a brain wave signal from a human body 10 and outputs signals to signal lines 18, 20, and 22 to a preamplifier 24, and the output of the preamplifier 24 is coupled to the analog input of an A/D conversion circuit 28 through a filter circuit 26, and a digital intensity language on a bus 34 converted to a digital language is read by a mapping computer 36. This computer 36 obtains the characteristics of an analog signal on a line 32, and this characteristic is mapped to oarameters of MIDI. Thus, the frequency of the tone outputted from a music synthesizer output device 38 is controlled by the intensity of the signal on the line 32.
