Title:
ANSWER TOTALIZER/ANALYZER
Document Type and Number:
WIPO Patent Application WO/2005/046091
Kind Code:
A1
Abstract:
An answer totalizer/analyzer comprising an auxiliary light projector/receiver for relaying projection/reception of light between a center unit and answering units in addition to the center unit and the answering units transfering a signal by means of an optical pulse. The center unit assigns an answering period to each of a plurality of answering units by an answer command signal. Each answering unit can answer a question with a small number of pulses using a method for representing the content of an answer by the position of optical pulse transmission time in the answering period assigned to the answering unit. The center unit judges and detects the answer signal from each answering unit by that communicating method and totalizes/analyzes the answers. Since projection/reception of light between the answering units and the center unit is relayed using the auxiliary light projector/receiver, conventional difficulties of using the answer totalizer/analyzer at a large site and using a large number of answering units can be eliminated resulting in convenient and stabilized totalization/analysis of answers.
