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.

A sentence evaluation apparatus evaluates a sentence which is input. The sentence evaluation apparatus includes an acquisition device and a processor. The acquisition device acquires information indicating a first input sentence and information indicating a second input sentence. The processor executes information processing on the information acquired by the acquisition device, using an algorithm based on machine learning. The processor includes a first encoder that recognizes the first input sentence and a second encoder that recognizes the second input sentence, in the algorithm based on the machine learning. The processor generates evaluation information indicating evaluation on the first input sentence with reference to the second input sentence, based on a result of recognition by the first encoder on the first input sentence and a result of recognition by the second encoder on the second input sentence.

A translation device is configured to acquire utterance spoken by a speaker in a first language and translate contents of the utterance into a second language for information presentation, and includes an input unit, a controller, a notification unit, and a storage. The input unit acquires the utterance in the first language and generates voice data from the utterance. The controller acquires a first evaluation value. The notification unit presents the speaker with information on utterance reinput request. The notification unit presents first information on utterance reinput request when the first evaluation value is less than or equal to a first predetermined value. The controller generates new voice recognition data with reference to the past voice recognition data and voice recognition data of reinput utterance, when the voice recognition data of the reinput utterance has an evaluation value less than or equal to a predetermined value.

A display device is provided which is capable of inhibiting a localized elevation in the temperature of a casing thereby uniformalizing the surface temperature distribution over the casing. A display device includes: a display panel having surface arrays of plural pixels for displaying an image by light radiation control on a pixel to pixel basis; an electronic component forming a control circuit configured to perform the light radiation control; a casing housing the display panel and the electronic component therein; and a flat heat-conductive sheet interposed between the display panel and the casing and between the electronic component and the casing.

A reflective plate comprises a substrate, a plurality of protrusions each formed on the substrate and having a curved surface, and a reflective film formed on the substrate having the protrusions, wherein a planar shape of each of the protrusions is indefinite, and when a frame line of the planar shape of each of the protrusions is divided into fine line segments, the line segments are pointed in all directions or in predetermined directions. This improves reflective properties such as dispersion properties.

A method of measuring quantities that indicates the state of an electrochemical device having an electrode and an ionic conductor, such as material properties or a residual capacity, without disassembling the device. The quantities are measured by comparing (a) a series of theoretical data of an electrical characteristic of the device obtained by combining at least one of an electron transportation model of the electrode, an ion transportation model of the electrode, an ion conduction model of the ionic conductor and a model of an electrochemical reaction taking place in an interface between the electrode and the ionic conductor, with a potential model of the electrode, with (b) a series of measured data of the electrical characteristic of the electrochemical device.
