Title: Communication method, method for detecting position of receiver and transmitter
Inventor: KAWASHIMA EIKO
IPC: H04B7/10
Filed: 1999-08-19
Abstract: PROBLEM TO BE SOLVED: To provide a communication method which can extend a communication possible range. SOLUTION: Synchronized transmission signals are simultaneously radiated from first and second antennas 1 and 2 of a transmitter for transmission. Information is transmitted by using an interference wave obtained by interfering with radio waves radiated from the antennas. Since the intensity of an electric field in the inside part of an interference pattern in the interference wave becomes stronger, a maximum transmittable area becomes wider than that of one regular antenna. In the part of the node of the interference pattern, the radio wave cannot be received. However a transmission state at the time of radiating the radio wave is adjusted and the interference pattern is changed and thereby, information can be transmitted to an arbitrary receiver existing in the maximum area.

Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To provide a passenger protecting device to make compact a car body compatible to the decrease of passenger deceleration at a further higher dimension. SOLUTION: A passenger protecting device to reduce the deceleration exerted on a passenger 2 during a vehicle clash comprises a seat 1 having a seat belt 3 supported at a car body 4 movably along the direction of a force exerted on a car body during the occurrence of a clash and constraining a seating passenger; a first acceleration means 7 to exert acceleration, in the same direction as a direction, in which a clash load is inputted to a car body; and a second acceleration means 15 to exert acceleration in a reverse direction to an input direction on the seat.  This constitution increases a constrainment force of the seat belt to regulate movement to the front of a passenger by generating deceleration higher than car body deceleration at the initial period of a clash, causes the occurrence of acceleration in an advancing direction to the seat by the second acceleration means, offsets an inertia force to a front exerted on a passenger during the occurrence of a clash, and early equalizes deceleration of the car body and seat to that of the passenger.
