Provided is an elevator system capable of improving the operation efficiency of an elevator. An elevator system according to the present invention includes: first processing circuitry to receive destination floor information transmitted from a movable body having a movement mechanism and second processing circuitry and being capable of boarding and alighting from a car of an elevator, to assign the car, in which a plurality of onboard positions are set, to a call based on the destination floor information received, and to assign one of the plurality of onboard positions to one movable body based on a destination floor of the movable body. The first processing circuitry transmits to the movable body information indicative of the onboard position assigned to the movable body.

In performing SVD-MIMO transmission, a set-up procedure is simplified while assuring a satisfactory decoding capability with a reduced number of antennas. A transmitter estimates channel information based on reference signals sent from a receiver, determines a transmit antenna weighting coefficient matrix based on the channel information, calculates a weight to be assigned to each of components of a multiplexed signal, and sends, to the receiver, training signals for respective signal components, the training signals being weighted by the calculated weights. On the other hand, the receiver determines a receive antenna weighting coefficient matrix based on the received training signals.

Wireless communications system, wireless communications apparatus, wireless communications method and computer program for wireless communication

Random access operation is performed under a communication environment in which a plurality of communication modes having different transmission rate coexist with small overhead. A high-grade communication station spoofs information of a packet length and a rate in a decoding portion so that a value of (packet length)/(rate) corresponds to a duration where the communication is hoped to be stopped. The other station receiving the spoofed information receives the rest of the packet with the designated rate during the interval designated by the value of (packet length)/(rate). In this case, the packet length and the rate are not those of actually transmitted packet so that this packet is discarded.

An elevator device that can continuously evacuate any evacuee left in a building by using an elevator. The elevator device includes a control device configured to maintain an evacuation operation mode corresponding to a rescue floor concerned when a car operation instructing device is operated on the rescue floor concerned before a predetermined time passes from when the car stops at the rescue floor concerned during the evacuation operation mode corresponding to the rescue floor concerned, and release the evacuation operation mode corresponding to the rescue floor concerned when the car operation instructing device is not operated on the rescue floor concerned before the predetermined time passes from when the car stops at the rescue floor concerned during the evacuation operation mode corresponding to the rescue floor concerned.

Elevator device

An elevator device enabling efficient evacuation of people left in a building is provided. The elevator device includes: an evacuation operation mode request switch provided in a hall of an elevator on a rescue floor; a car that if the evacuation operation mode request switch is kept in an operated state, keeps operating in an evacuation operation mode in which the car moves between the rescue floor and an evacuation floor; and an operation control device that is provided in the hall of the elevator on the rescue floor, and if the operation control device is operated when the car is stopped at the rescue floor, moves the car to the evacuation floor.

Elevator device including evacuation operation mode request switch

An elevator device includes: a first reader, a second reader, a determination section, and a request output section. The first reader is provided in a hall of an elevator. The second reader is provided in a car of the elevator. In the case where identification information has been read by the first reader, the determination section determines whether or not the identification information has been read by the second reader before the reading thereof by the first reader. On the basis of the identification information read by the first reader, the request output section outputs a registration request for a call to a control section. In the case where the determination section determines that the identification information has been read by the second reader, the request output section does not output a registration request for a call corresponding to the identification information to the control section.

Embodiments include a communication device, having a wireless communication processor. The communication device includes an antenna connected to a feeding point of the wireless communication processor. The communication device also includes a metal component disposed proximal the antenna and a circuit board including a ground plane. The communication device further includes a first conductive line and a second conductive line which connect the ground plane to two locations on the antenna, on one end and the other end of a location proximal the metal component.

Communication terminal

A method and system for predicting a moving picture to be implemented in an encoder is provided. The system includes a plurality of reference picture memory areas for storing reference pictures to be used for prediction and a prediction generation section that includes a motion compensator and memory updater. The motion compensator receives a parameter representing the motion between an image to be predicted and a reference picture stored in the reference picture memory area and a parameter representing the reference picture memory area to be used for prediction, and generates a predicted image by using the reference picture stored in the reference picture memory area indicated by the parameter representing the reference picture memory area. The memory updater carries out dynamic allocation of reference picture memory areas required for prediction and judges whether to store new reference pictures additionally.

Moving picture prediction system

A moving picture encoder and encoding method for encoding a moving picture signal are disclosed. The moving picture encoder includes a plurality of reference picture memory areas, each area storing picture data of a reference picture to be used for prediction; and a prediction picture generator including a motion compensator that generates the predicted picture by using the picture data stored in the reference picture memory area, a parameter representing a motion between an image to be predicted and the reference picture and prediction mode information indicating a prediction mode corresponding to a prediction method used for generating a predicted picture, and a memory updater that controls a timing of updating the picture data of a full frame stored in the reference picture memory area; and a multiplexer that multiplexes an information representing memory update in a bitstream.
