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

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

A power converter includes at least one arm having a plurality of converter cells cascaded to each other. Each of the converter cells includes a pair of input/output terminals, a plurality of switching elements, and a power storage element. The power storage element is electrically connected to the input/output terminals through the switching elements. A control device generates a control signal for controlling on and off of the switching elements of each converter cell. The control device generates the control signal by pulse width modulation control based on a modulation command signal including an AC component having a fundamental frequency and corresponding to a command value of an output voltage between the input/output terminals, in each converter cell, such that a harmonic component included in the output voltage and having a predetermined frequency that is an integer multiple of the fundamental frequency is suppressed.
