Title: Method and equipment for measuring distance
Inventor: HORIUCHI YASUYUKI
IPC: G01S11/16
Filed: 1993-11-02
Abstract: PURPOSE:To execute measurement of a distance without being affected by the condition of propagation, by a method wherein information transfer mediums different in speed of propagation are transmitted and received by receivers and the distance between a point of transmission and a point of reception is calculated by using the time of arrival of the fast information transfer medium as a reference time. CONSTITUTION:A transmitter is composed of transmitting circuits 11a and 11b and a receiver is constructed from receiving circuits 21a and 21b, pulse generating circuits 22a and 22b and a time measuring circuit 23. When the distance between two points of transmission and reception is denoted by L and the respective speeds of propagation of high-speed and low-speed transfer mediums by V1 and V2, the time T1 of propagation of the high-speed transfer medium equals L/V1 and the time T2 of propagation of the low-speed transfer medium L/V2, and therefore a difference T in the time of propagation is given by T=L/V2-L/V1. When V2 is a much smaller value than V1 herein, the difference may be expressed by T=L/V2, and therefore the distance can be determined as L V2.T on the basis of a difference in the time of arrival between the two transfer mediums and the speed of propagation of the information transfer medium of the low speed.

Title: Transmission/reception device
Inventor: KAWATE FUMITAKA
IPC: G06F3/048
Filed: 1991-10-22
Abstract: PURPOSE:To ensure the more realistic communication among the users by limiting an arriving range of the message sent from each user and transmitting the messages only to the users included in the limited range when many users are simultaneously included in a single virtual space. CONSTITUTION:A virtual space 1 formed based on the at least a three- dimensional space is projected on the display devices 2A, 2B... of plural terminals for execution of the communication. Under such conditions, a transmitter means 3 transmits the transmission information containing the weighting that is selectively decided by the position of the character projected on the means 2A. Then a three-dimensional virtual space, e.g. a town is projected via an Ethernet based on the characters and the weights shown on the coordinate screens of the means 2A, 2B.... In this case, however, a projection pattern is limited within a range where the messages transmitted by the users arrive, so that the messages can be transferred only to the users included in the range. Thus the more realistic communication is attained.
