A diagnostic device includes a reception unit and a determination unit. The reception unit is configured to receive context information and sensing information. The context information corresponds to a certain operation of a target item that constitutes a target device. The context information is a piece of a plurality of pieces of context information each describing an operation of the target item determined depending on a type of operation of the target device. The sensing information is on a physical quantity that varies in accordance with the operation of the target item. The determination unit is configured to determine a state of the target item based on the sensing information detected while the target item is performing the certain operation, and based on a model corresponding to the received context information. The model is a model of one or more models respectively defined for one or more pieces of the context information.

Diagnostic device, computer program, and diagnostic system

A device includes: a first acquiring unit to acquire context information corresponding to running operation among pieces of context information; a second acquiring unit to acquire detection information output from a detecting unit detecting a physical quantity of a target device; an extracting unit to extract, from the detection information, feature information indicating a feature of the detection information in an interval including a specific operation interval of the target device; a selecting unit to select reference feature information used as reference based on the feature information, and sequentially select pieces of target feature information; a calculating unit to calculate a likelihood of a process interval based on a comparison between the reference feature information and each piece of target feature information; a determining unit to determine whether the target feature information corresponding to the likelihood is included in the process interval based on the likelihood; and an estimating unit to estimate the process interval based on a determination result.

Diagnosis device, diagnosis system, diagnosis method, and computer-readable medium

A malfunction determining apparatus for determining a malfunction of a target apparatus includes a receiver that receives, from a target apparatus, a plurality of items of physical data having frequency bands that are different from each other and circuitry that analyzes the received physical data to identify, for each of the operating modes, at least one of the physical data items having a specific feature from among the plurality of items of physical data that are received from the target apparatus, stores in a memory, for each of the operating modes, information indicating at least one sensor of the multiple sensors that has output the at least one of the physical data item that is identified, and determines abnormality of the target apparatus operating in a specific operating mode, using only the physical data output from the at least one sensor stored in the memory for the specific operating mode.

Malfunction determining apparatus, malfunction determining system, malfunction determining method, and recording medium

An information processing apparatus includes a sound collector configured to collect an operation sound of a sound collection target device to obtain sound data; a context information obtaining unit configured to obtain context information at a time of an operation of the sound collection target device; a feature generator configured to generate feature of sound data corresponding to the context information; and a clustering unit configured to generate an operation status table of the sound collection target device by using the feature.

Information processing apparatus, information processing method, and computer-readable storage medium for detecting an abnormity from sound data

In response to receiving a sound signal representing sounds originated from a viewer for each one of a plurality of projectors, which are collected at each one of a plurality of microphones that are associated with the plurality of projectors, a projector control apparatus generates, for each one of the plurality of projectors, distance information indicating a distance of the viewer relative to the projector using the sound signal, and determines a layout of a projection image to be displayed by at least one of the plurality of projectors, based on the distance information of each one of the plurality of projectors.

Apparatus, method, and system of controlling projection image, and recording medium storing image projection control program

Disclosed is an image processing apparatus including a reading unit that reads a document, an image forming and outputting unit that performs an image forming and outputting process, a read image transfer circuit that processes and transfers read image information so as to input the read image information to a controller of the image processing apparatus, an output image transfer circuit that processes and transfers output image information so as to input the output image information to the image forming and outputting unit, and a clock oscillator that generates clocks to be supplied to the read image transfer circuit and the output image transfer circuit, wherein the clock oscillator individually alters clock supply states for supplying the clocks to the read image transfer circuit and to the output image transfer circuit, depending on an operating mode of the image processing apparatus.
