Abstract: A paper jam indication detection device is a paper jam indication detection device that detects an indication that a paper jam will occur in a paper feed device, the paper jam indication detection device including: a sound collector that collects a friction sound produced by friction between a plurality of sheets of paper when the paper is fed from a holder holding the plurality of sheets of the paper; an indication detector that detects an indication that a paper jam will occur in the paper feed device based on a decrease in the friction sound collected by the sound collector; and a signal outputter that, when the indication is detected by the indication detector, outputs, to the paper feed device, a signal for stopping the paper from being fed from the holder.

Abstract: Provided is an area reproduction system including a reproduction unit including a speaker array, a processing unit that processes a reproduction sound to be output from each of a plurality of speakers included the speaker array, based on a control line including a reproduction line that strengthens a sound wave radiated from the speaker array and a non-reproduction line that weakens the sound wave, so that an audio beam of a predetermined sound pressure or more is radiated only to the reproduction line, the control line being substantially parallel with the speaker array and being set in a position separated from the speaker array, and a directional angle control unit that adjusts a phase of the reproduction sound so that a radiating direction of the audio beam is deflected by a specified angle, in which each of the plurality of speakers outputs the processed and adjusted reproduction sound.

Abstract: An occupied seat detection device includes: at least one receiver that is disposed in a space including a plurality of seats and receives at least one of sound generated inside the space or sound generated outside the space; an acoustic characteristics analyzer that calculates, from a signal received by the at least one receiver, temporal characteristics or frequency characteristics of the sound in the space; and a detector that detects whether an occupant is present or whether an occupied seat is present inside the space, based on the temporal characteristics or the frequency characteristics calculated by the acoustic characteristics analyzer, and outputs a detection result.

Abstract: An action estimation device includes: an obtainer that obtains sound information pertaining to an inaudible sound, the inaudible sound being a sound in an ultrasonic band collected by a sound collector; and an estimator that estimates an output result, obtained by inputting the sound information obtained by the obtainer into a trained model indicating a relationship between the sound information and action information pertaining to an action of a person, as the action information of the person.

Abstract: A paper jam indication estimation device estimates an indication that a paper jam will occur in a paper feed device, and includes: a sound collector that collects a friction sound produced between sheets of paper when the paper is fed into the paper feed device from a holder holding a plurality of sheets of the paper; an estimator that, based on an output result obtained by inputting information pertaining to the friction sound into a trained model that is a machine learning model which has been trained, estimates a presence or absence of an indication that a paper jam will occur in the paper feed device; and an outputter that, when the estimator estimates that the indication that a paper jam will occur is present, outputs, to the paper feed device, a signal that stops the paper from being fed into the paper feed device.

Abstract: A sound measuring device includes: a light source that emits a laser beam; a frame including at least one reflective surface that faces a predetermined space through which sound travels, and transversely surrounds the predetermined space with respect to a sound propagation direction; and a light receiver that receives the laser beam multiply reflected by the at least one reflective surface. The at least one reflective surface is disposed to multiply reflect and cross the laser beam in the predetermined space as viewed from the sound propagation direction.
