High intensity photic stimulation system with protection of users
First Claim
1. A high intensity photic stimulation system, comprising:
- (a) a trigger signal circuit providing a trigger signal;
(b) a lighting subsystem comprising a triggerable high intensity light source;
(c) a lamp trigger circuit, said light source being connected to said lamp trigger circuit to be triggered in response to the trigger signal;
(d) a shutter viewer trigger circuit;
(e) at least one shutter viewer switchable between a transmissive state and an attenuating state, said shutter viewer being connected to said shutter viewer trigger circuit to be triggered in response to the trigger signal, each said shutter viewer being movable to a selectable, changeable position with respect to said lighting subsystem; and
(e) a communication circuit remotely locatable from said lamp trigger circuit and said shutter viewer trigger circuit and having a movable physical location with respect thereto to transmit the trigger signal to said lamp trigger circuit and to said shutter viewer trigger circuit.

Abstract
In a method and system to provide high intensity photic stimulation to disable target subjects, a high intensity light source is activated by trigger signals to produce light flashes in commanded patterns of duration and frequency. A user views a field illuminated through a shutter viewer such as shutter goggles. The goggles are gated to a light blocking state in response to trigger pulses. The light blocking state has a wider time width than the light flashes from the light source produced in response to the trigger pulses to avoid the need for close synchronization. The target subjects are exposed to the high intensity light flashes while the light flashes are blocked from the view of users. Due to a low duty cycle, the users'"'"' view through the shutter goggles is unaffected by the intermittent opacity of the shutter goggles.

14. A method of high intensity photic stimulation by a light source comprising:
- (a) producing a trigger signal having a predetermined pulse pattern;
(b) providing a shutter viewer, the shutter viewer being switchable between a transmissive state and an attenuating state, to view a field illuminated by the light source and locating the shutter viewer in a selected, changeable position with respect to the light source;
(c) transmitting the trigger signal to trigger pulsed transmission from the light source circuit and to switch the shutter viewer to the attenuating state in response to the trigger signal;
(d) triggering the high intensity light source in response to the trigger signal; and
(e) switching the shutter viewer to the attenuating state in response to the trigger signal, wherein producing the trigger signal comprises providing the trigger signal from a location selectable with respect to the light source and the shutter viewer. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
