专利汇可以提供Attention-level analyzer专利检索，专利查询，专利分析的服务。并且An attention-level analyzer comprising an electroencephalograph instrument the output of which is filtered by an analog filter and a digital filter to pass only brain waves in the 8-13 Hz band, which is the band of frequencies of the inattentiveness wave. An output from the filters actuates a clock which, if advanced in time sufficiently within the predetermined timing interval of another clock, actuates a tone generator. The output of the first clock also advances a third clock or counting means in time which, if advanced sufficiently within the predetermined time interval of a fourth clock, actuates another tone generator which may be placed to alert a monitor.，下面是Attention-level analyzer专利的具体信息内容。

权利要求

1. Apparatus for determining the level of attention of a human subject comprising, in combination: wave-detection means adapted for connection to the subject''s head for obtaining an electrical wave output corresponding to the brain waves of the subject; filter means for filtering said electrical wave output, said filter means passing signals having frequencies lying in the attentiveness band and cutting off lower and higher frequency signals; first clocking means to which the output of the filter means is fed as an input for establishing repeatable time intervals and for producing an output signal if the cumulative duration of inattentiveness signals exceeds a predetermined amount of time for a given timing interval; and first alarm means for producing an alarm signal upon receipt of an output signal from said clocking means.

2. Apparatus as in claim 1, further including: second clocking means to which the output of the first clocking means is fed as an input for producing an output signal if the number of its input signals during a given timing interval equals a predetermined number; and second alarm means for producing an alarm signal upon receipt of an output signal from said second clocking means.

3. Apparatus as in claim 1, wherein said wave-detection means comprises an electroencephalographic apparatus.

4. Apparatus as in claim 2, wherein said filter means comprises an analog filter in series with a digital filter.

5. Apparatus as in claim 1, wherein said first timing means comprises a pair of clocks, A and B, clock A being of the continually recycling type and acting to recycle itself and clock B after each timing interval and clock B being of the type which is advanced during each timing interval in accordance with the cumulative duration of any inattentiveness signals coming from the filter means.

6. Apparatus as in claim 1, wherein said first alarm means comprises a tone generator.

7. Apparatus as in claim 1, wherein: said wave-detection means comprises electroencephalographic apparatus; said filter means comprises an analog filter in series with a digital filter; said first timing means comprises a pair of clocks, A and B, clock A being of the continually recycling type and acting to recycle itself and clock B after each timing interval and clock B being of the type which is advanced during each timing interval in accordance with the cumulative duration of any inattentiveness signals coming from said first filter means; and said first alarm means comprises a tone generator.

8. Apparatus as in claim 7, further including: second clocking means to which the output of the first clocking means is fed as an input for producing an output signal if the number of its input signals equals a predetermined number during a given timing interval, said second timing means comprising a clock and a counter, the clock being of the continually recycling type which acts to recycle itself and the counter after each timing interval, and the counter Producing an output signal if its count equals said predetermined number during said given timing interval; and second alarm means comprising a tone generator for producing an alarm signal upon receipt of the output signal from said counter.
