STAGE EFFECT EXECUTING METHOD
Publication number: JP7201205 (A) Publication date: 1995-08-04
PURPOSE:To attain a required stage effect at a large degree of freedom with a good reproduction by operating an stage effect rendering device according to a stage effect program on the basis of position information through ultrasonic signals from the moving body on a stage.
CONSTITUTION:Ultrasonic signals d1-d4 are transmitted from an ultrasonic wave generating device 30 of a body A moving irregularly on a stage. The signals d1-d4 are received by an ultrasonic wave detection unit 40, and at a CPU 10 coordinates information showing the position of the body A in a space coordinates system set on the stage 2, is obtained. The information is used as cueing signals and a stage effect rendering device is operated according to a predetermined stage effect rendering program.; The device 30 is started through a wave generator 20 by means of the CPU 10, and after the body A reaches a set position, a lighting device 50, an accoustic device 60 and the like are operated.
Automatic control system for lighting projector.
Publication number: EP0591899 (A1) Publication date: 1994-04-13
A radio wave signal is transmitted from a radio wave transmitter according to a command from a central control unit, and a supersonic wave is transmitted from a supersonic wave transmitter held by a moving object according to this radio wave signal. A time counter in a supersonic wave detecting device determines the time required from the transmission of the radio wave signal to the detection of the supersonic wave. A coordinate position of the object is calculated on the basis of the thus-obtained time data from a plurality of the supersonic wave detecting devices and positional data of the supersonic wave detecting devices to control the lighting direction of a lighting projector according to a command signal from the central control unit referring to a positional data of the lighting projector.; In the case of a plurality of moving objects, supersonic wave transmitters are separately held by the objects, and radio wave signals identified correspondingly to the supersonic wave transmitters are alternately transmitted from the radio wave transmitter. The supersonic wave transmitters detect the radio wave signals identified correspondingly thereto, thereby transmitting respective supersonic waves.
AUTOMATIC CONTROL DEVICE FOR LIGHTING SYSTEM
Publication number: JP6215878 (A) Publication date: 1994-08-05
PURPOSE:To provide an automatic control device for lighting system capable of attaining the highly precise control of a lighting system according to a moving target body with a simple structure.
CONSTITUTION:A radio signal is transmitted from a radio transmitting device according to a command from a central control device 10, and an ultrasonic wave is transmitted from an ultrasonic transmitting device 30 held by a moving target body according to this radio signal. The timer counter 41 of an ultrasonic detecting device 40 measures the time from the transmission of radio signal to the detection of ultrasonic wave.; The coordinate position of the target is calculated from the thus-obtained time data from a plurality of ultrasonic detecting devices 40 and the position data of the ultrasonic detecting devices 40, and in reference to the position data of a lighting system 50, the lighting direction of the lighting system 50 is controlled with the target as a standard according to the command signal from the central control device 10. When there are a plurality of moving targets, the ultrasonic transmitting device 30 is held by each of them, the radio signal identified in conformation to each ultrasonic transmitting device 30 is successively transmitted by the radio transmitting device, and the ultrasonic transmitting device 30, the ultrasonic wave is transmitted by detecting the identified radio signal corresponding to itself.
CONTROL OF LIGHTING SYSTEM FOR STAGE
Publication number: JP6124787 (A) Publication date: 1994-05-06
PURPOSE:To control automatically illumination similarly to rear illumination according to a position of a moving object to be illuminated by obtaining always correction data on the position of the object to be illuminated to carry out unprescribed movement on the stage.
CONSTITUTION:A central control device 10 has a function to change illuminating conditions such as an illuminating direction and a color, brightness and a light tip shape of illuminating light to respective lighting systems 40, and also calculates a distance (d); between an ultrasonic wave oscillator 20 and respective ultrasonic wave detectors 30 by carrying out an oscillation control command to the ultrasonic wave oscillator 20 held by an object to be illuminated to carry out unprescribed movement on the stage and a data transmission control command containing a count staring command to the respective ultrasonic wave detectors 30, and thereby, it converts a position of the oscillator 20 into a neumeric value as space coordinates, and calculates correction data on a position of the object to be illuminated to carry out the unprescribed movement according to this space coordinate value, and corrects and controls automatically an illuminating condition of the lighting systems 40 in a highly accurate illuminating direction similarly to rear illumination by means of this data.
