A three-dimensional display system for co-spatial point display of information emanating from at least two biophysical sources. The system includes a rigid, transparent three-dimensional structure within which is provided co-spatial visual display elements arranged in a three-dimensional geometry at regular coordinate addresses. Information input terminals, including terminals for biological interface, are provided. Also furnished is logic for assigning a three-dimensional coordinate address, at uniform time intervals, for the informational input from each of the biological sources. Each of the display elements are energized in a fashion that is input-responsive to the coordinate addresses corresponding to the system inputs. The system is further provided with detectors for alerting the users to spatial and temporal coincidence of energized visual elements resultant from simultaneous inputting of like coordinate addresses by the biophysical source.

Biophysically controlled game system

A combined phase and frequency modulation device for modulating a data signal in order to generate a plurality of narrow band signals for a communication system is disclosed, characterized by a direct synthesis phase locked loop for generating an output data signal having a selected frequency, a signal divider and phase modulator circuit, and a frequency multiplier for multiplying a modulated signal to produce an output having a desired frequency. The signal divider and phase modulator circuit includes a frequency divider which produces two quadrature related signals from the output data signal. A modulator connected with the frequency divider generates a suppressed carrier double sideband signal from one of the quadrature related signals. A summing device connected with the frequency divider and with the modulator combines the carrier signal with the other quadrature related signal to produce the modulated output signal which is multiplied by the frequency multiplier.
