Abstract:
The information display device includes a surface member, a display, a light measurement unit, and a controller. The surface member is at least partially transmissive for light. The display is disposed on a back side of the surface member and is capable of displaying a display image including an information area for displaying information and a non-information area for displaying no information. The light measurement unit measures the amount of ambient light around the information display device. The controller acquires the amount of light measured by the light measurement unit and changes a pixel value of a display image according to the amount of light so that the display is difficult to be seen through a surface of the surface member.
Abstract:
The image management device (13) monitors a face of a first person whose image is included in a first image area of a first image acquired from the first imaging device (11) and a posture of the second person whose image is included in a second image area of the first image. The image management device (13) monitors a face of a second person whose image is included in a first image area of a second image acquired from the second imaging device (12) and a posture of the first person whose image is included in a second image area of the second image. The image management device (13) determines a state of the first person based on the face or the posture of the first person, determines the state of the second person based on the face or the posture of the second person, and outputs the determination result.
Abstract:
A sound collecting system includes a plurality of sound collecting units that collect sound and a sound collecting device. The plurality of sound collecting units send sound collection data including audio data and time data to the sound collecting device. The sound collecting device includes a processor that manages time for the plurality of sound collecting units and receives an instruction specifying a sound collecting location, and an output unit. The processor of the sound collecting device synthesizes the audio data of the plurality of sound collecting units on the basis of the time data of the plurality of sound collecting units, and outputs, from the output unit, the audio data of the sound collecting location.
Abstract:
A noise reduction device includes: a noise detector that detects noise in a space at least partially surrounded by a shell; a noise controller that generates a control sound signal for reducing the noise detected by the noise detector; and a control sound outputter that outputs control sound to the space based on the generated control sound signal. A seat that is reclinable including a recliner having a seat surface at a variable angle with respect to a reference plane is provided in the space. When L (cm) represents the length of the recliner in the front-to-back direction, the control sound outputter is provided at a height of L×sin θ+8 (cm) above the reference plane where θ is between two degrees and eight degrees, inclusive.
Abstract:
An information display terminal includes a surface member, a touch panel, and an information terminal body. The surface member is to be fixed to a structure. The touch panel is configured to be curved and has a first surface and a second surface that are opposite to each other. The first surface is adhered to the surface member. The information terminal body is to be attached to the structure and is configured to receive an input from the touch panel. The second surface of the touch panel is apart from the information terminal body. The information terminal body is configured to be removable from the structure.
Abstract:
A wireless communication control method of the present disclosure is a wireless communication control method controlling communication between a first wireless communication apparatus, and a first external device and controlling communication between a second wireless communication apparatus and a second external device, by a server apparatus, the method including receiving a connection request to the first external device from the first wireless communication apparatus, and causing the first external device to connect with the second wireless communication apparatus if the second wireless communication apparatus has been connected with the second external device upon receiving the connection request.
Abstract:
The communication system includes a plurality of communication devices, and the communication devices form a hierarchical structure having two or more levels where an upper-level communication device is connected to one or more lower-level communication devices. In this communication system, a communication device connected to lower-level communication devices sequentially applies, to each of the connected lower-level communication devices, an operation of turning on one lower-level communication device and transmitting an address to the turned-on lower-level communication device. The address is set on the basis of the sequence of turning on the lower-level communication devices.
Abstract:
A display terminal according to an exemplary embodiment of the present disclosure includes a display that is mounted in a reclinable seat and displays various kinds of information; a receiver for receiving reclining angle information of the seat; a tilt detector for detecting a tilt of the display; and a switching unit for switching between portrait and landscape view on the display. The switching unit switches between portrait and landscape view of the various kinds of information based on the reclining angle information, received by the receiver, of the seat and the tilt, detected by the tilt detector, of the display, and outputs the various kinds of information to the display.
