摘要： In order to enable noises entering the ear from random directions to be muted without wearing headphones, this muting device is provided with: a super-directional microphone that detects noises in spot areas around the ear at pinpoints; and an ultrasonic speaker that modulates and outputs a carrier signal supplied by a transmitter according to noise signals detected by the super-directional microphone. Furthermore, an adaptive filter is provided, and the adaptive filter supplies noise signals with the opposite phase to noises detected by the super-direction microphone, and transmits an ultrasonic signal from the ultrasonic speaker toward the eardrum of a human.

摘要： Provided is an. emotion. estimating apparatus capable of precisely estimating an emotion and mental state of a measurement subject by using a non-contact pulse detection technology. The emotion estimating apparatus forcibly performs re-sampling processing of digital biometric data generated by converting a heart rate signal to digital data after extracting data for one cycle at an RR interval, and obtains coefficients of harmonic components by a DCT conversion processing unit. From the coefficients of the harmonic components, AC components are removed by LPFs, whereby a coefficient data array is obtained.. The coefficient data array is compared to a dictionary data group, in which dictionary data is a characteristic quantity indicating an emotion or mental state, and a similarity therebetween is calculated, whereby an emotion or mental state of a subject is estimated on the basis of the heart rate signal of the subject.

摘要： A first oscillation circuit in which a helical antenna is used as a part of an element for a resonance circuit and a second oscillation circuit in which a loop antenna is used as a part of an element for a resonance circuit are caused to oscillate at substantially the same frequency. When a human body approaches the helical antenna and the loop antenna, the frequency difference between the first oscillation circuit and the second oscillation circuit increases. This frequency difference is extracted using a BPF.

摘要： A sound wave sensor, capable of reliably detecting presence or absence of a banknote very easily with use of sound waves, is provided. The sound wave sensor includes a sounding body 2 that outputs a sound wave signal of a predetermined frequency, an echo body 3 opposed to the sounding body 2 in a direction in which the sounding body 2 outputs the sound wave signal, the echo body 3 being provided at a position where the sound wave signal resonates at the predetermined frequency; a slit 5 through which a sheet-like banknote 4 passes, the slit 5 being provided between the sounding body 2 and the echo body 3; and a resonance determination unit 6 that determines a resonant state of the frequency output from the sounding body 2. The resonance determination unit 6 determines a resonant state by detecting variation in power consumption of the sounding body 2.
