Abstract

A heater is provided which, when warm air blows into an indoor space, suppresses the warm air from rising even when the warm air has buoyancy, and which enables delivering the warm air efficiently to the floor surface. The heater 1 comprises a second air passage 17 which, when warm air is blown out of a first air passage 16, blows out an airflow that has a lower temperature than the warm air blown out of the first air passage such that the airflow flows vertically above the warm air blown out from the ceiling and the first air passage 16; thereby, it is possible to suppress the warm air blown out of the first air passage 16 from rising due to buoyancy by means of the airflow blown out of the second air passage 17; this makes it possible to efficiently deliver the warm air to the floor surface.

Abstract

An abnormality detection device (23) is provided with a travel determination unit (24) and a sensor abnormality detection unit (25). The travel determination unit (24) determines whether or not the traveling state of an electric railway vehicle is a non-traveling state in which the speed of the electric railway vehicle is less than a speed threshold value. When the electric railway vehicle is not in the non-traveling state, the sensor abnormality detection unit (25) detects that a rotation detector (4) not outputting a rotation detection signal is abnormal when an operation command signal, which indicates an operation command instructing the operation of the electric railway vehicle, indicates a power running command or a brake command. When the electric railway vehicle is in the non-traveling state, the sensor abnormality detection unit (25) does not detect that the rotation detector (4) not outputting a rotation detection signal is abnormal when the operation command signal indicates a power running command or a brake command.

Abstract

This steady range determination system (100) determines the steady range of a multi-valued signal in operation data that includes the multi-valued signal. A conversion unit (122) converts the multi-valued signal into one or more binary signals using a threshold value. A prediction unit (123) inputs the binary signal converted by the conversion unit (122) to a prediction model (133) and calculates a converted-binary-signal prediction value. A range determination unit (126) calculates, on the basis of the converted-binary-signal prediction value and the threshold value, the probability that a signal value of the multi-valued signal included in the operation data is present within a range established on the basis of the threshold value. The range determination unit (126) determines the steady range of the multi-valued signal included in the operation data on the basis of the aforementioned probability.

Abstract

Embodiments disclose a method and system for a scene-aware audio-video representation of a scene. The scene-aware audio video representation corresponds to a graph of nodes connected by edges. A node in the graph is indicative of the video features of an object in the scene. An edge in the graph connecting two nodes indicates an interaction of the corresponding two objects in the scene. In the graph, at least one or more edges are associated with audio features of a sound generated by the interaction of the corresponding two objects. The graph of the audio-video representation of the scene may be used to perform a variety of different tasks. Examples of the tasks include one or a combination of an action recognition, an anomaly detection, a sound localization and enhancement, a noisy-background sound removal, and a system control.

Abstract

The power receiving coil (21) of a non-contact power supply device (1) includes a plurality of power receiving coil windings (21a, 21b) arranged along the moving direction of a moving body (2) and is disposed so that parts of the adjacent power receiving coil windings (21a, 21b) are overlapped with each other. A power supply performance is not therefore degraded even under the condition that a power transmission coil (12) is positioned at the boundary between the power receiving coil windings (21a, 21b). In addition, since one power receiving coil winding (21a) does not face two power transmission coils (12a, 12b) at a time, a magnetic field cancelling phenomenon can be prevented, enabling a stable power supply.

The control device has a first determination value and a second determination value, the first determination value being a time constant as a response value until stabilization of cooling/heating performances in refrigerant circulation of a refrigerating cycle, the first determination value being obtained by multiplying the time constant at the time of rising of a waveform indicating the cooling/heating performances calculated from a measurement value of the measurement sensor by a first constant set in advance, the second determination value being obtained by multiplying the time constant by a second constant set in advance smaller than the first constant. When an intermittent operation time from an operation start time of the compressor to an operation stop time of the compressor in the intermittent operation is larger than the first determination value, the control device increases the minimum frequency at the time of a subsequent operation of the compressor, and when the intermittent operation time is smaller than the second determination value, the control device reduces the minimum frequency at the time of the subsequent operation of the compressor.

Abstract

A capturing device (14) includes a driving mechanism control unit that drives one or more driving mechanisms (21a, 21b) to feed a tape-like enclosing member (31) toward the outside of a housing (32) by a target feed amount. When a space vehicle is positioned in a space enclosed by the enclosing member (31), the driving mechanism control unit causes the one or more driving mechanisms (21a, 21b) to house the enclosing member (31) inside the housing (32) until at least a part of the enclosing member (31) comes into contact with the space vehicle. The enclosing member (31) has a stable shape when being in a first shape in which a cross section orthogonal to a linear extension direction is curved.

Abstract

A coherent optical receiver comprises a local oscillator, a polarization- diversity actuator configured for modifying an optical signal output by the local oscillator and a 2 x 2 coupler for coupling the optical signal output by the polarization-diversity actuator and a modulated optical signal received from a coherent optical transmitter. The local oscillator thus provides a boosting effect to the amplitude-shift keying modulated optical signal. The coherent optical receiver comprises a controlling unit performing a domain-switching procedure acting on ellipticity main axis orientation and/or ellipticity phase shift for coarse control of the polarization-diversity actuator, and a phase-refining procedure acting on a controlled error signal injected in the phase of the optical signal output by the polarization-diversity actuator for fine control of the polarization-diversity actuator.
