During a maintenance inspection, an optical rope diameter measuring device is provided at a predetermined position along a path of a wire rope, rope diameter is measured at multiple measuring points while the elevator is driven in test mode, and diameter reduction at each measuring point is determined and stored as a first diameter reduction (S_S). During a subsequent maintenance inspection, rope diameter is similarly measured at each measuring point to determine diameter reduction constituting a second diameter reduction (S_S). Based on these two diameter reductions, the time at which diameter reduction will reach a predetermined threshold value is predicted for each measuring point, and the earliest time is displayed as a rope replacement time (S_S).

If any waveform software to be used is determined without taking into account the status of the other end of communication, the communication with the other end may possibly fail. Each of a plurality of radio devices observes its status, which dynamically varies in relation to that radio device, and transmits observation data, i.e., data representative of the observed status to a server apparatus. The server apparatus receives the observation data transmitted from the radio devices. Further, the server apparatus determines, on the basis of the observation data received from the radio devices, waveform software to be used for communications between or among the radio devices, and transmits the determined waveform software to the radio devices. Each of the radio devices receives the waveform software transmitted from the server apparatus and uses the received waveform software to control its own software radio communication means.

Provided is a method for effectively suppressing packet losses by burst losses without an increase in delay by adaptively or fixedly changing a size of an FEC encoded block even when the number of packets per unit time is small. Each communication deviceincludes a transmitting unitand a receiving unit. The transmitting unithas a function of calculating forward error correction (FEC) codes based on the number of packets per encoding time and a value of a burst loss time of a network line. The receiving unitdecodes an FEC encoded packet and measures line quality information of the network for transmission to the transmitting unit. The transmitting unittransmits the packets at equal intervals for as long as it is required for encoding, and can change a system for calculating FEC based on the burst loss time and the encoding time.

Communication device, system and method

Provided are a device, a system, and a method in which redundancy is changed in accordance with a line state, and thus the optimal redundancy can be set while the current settings are compared to the previous settings. A communication device measures line quality information from a received packet, and generates a redundancy change instruction based on information regarding a line. In a case where the communication device acquires line quality information for the second and subsequent times, the communication device compares the previous redundancy change instruction and the previous line quality information, to the current line quality information, and sets redundancy. Thus, it is possible to suppress the occurrence of congestion and satisfy a target value of the line quality, and to search for a condition which causes the redundancy to be the minimum.

A sound reproduction system includes an electro-acoustic transducer and a transducer driver for driving the electro-acoustic transducer. The transducer drive includes a filter which is configured to reproduce at a listener's location an approximation to the local sound field that would be present at the listener's ears in recording space, taking into account the characteristics and intended position of the electro-acoustic transducer relative to the listener's ears.
