Abstract

Abstract A portable survey system housed in a suitcase-like assembly, the cover of which supports an electronic display panel having a number of individually energizable display elements. A number of responder units, each connected with the display assembly to control the selective energization of a group of display elements, enables various individuals to cast votes which are preserved in total anonymity by the "pseudo-random" energization of the display and the use of a master control switch to prevent any display from being provided until after all votes are cast. The base of the case contains a plurality of separate compartments for receiving the individual responders for storage whereby the entire unit is self-contained and may be easily transported and subsequently set up for use in businesses, schools, hospitals, or merely for entertainment purposes.
