Abstract
A flash device has a flash tube which generates light in response to electrical energy. The amount of light emitted by the flash tube is monitored by a circuit which is connected to means for adjusting the electrical energy supplied to said flash tube when a predetermined amount of light has been emitted to thereby increase the effective life span of the flash tube and maintain intensity level of the flash tube within a given tolerance.
Claims24
An image reproduction apparatus, comprising:
- a substrate;
- an image on the substrate, the image being responsive to visible light applied thereto for converting the applied visible light into infrared light;
- a flash device applying pulses of visible light to the image on the substrate, the intensity and duration of the applied pulses being controlled to result in the conversion of said pulses into an infrared light replica of said image, the flash device comprising:
- a source of electrical energy;
- a flash tube emitting light in response to said electrical energy;
- means for adjusting the electrical energy in response to light emission of the flash tube;
- and
- an image forming layer responsive to said infrared light replica to develop a visible replica of said image.

An apparatus for reproducing an original image, comprising:
- a flash device for applying visible light to the original image, the flash device comprising:
- a source of electrical energy;
- a flash tube emitting light in response to said electrical energy;
- and
- means for adjusting the electrical energy in response to light emission of the flash tube;
- means responsive to energy from the original image resulting from the application of visible light thereto, for producing a pattern of infrared energy related to the original image;
- and
- thermographic means for developing a visible copy of the original image in response to the pattern of infrared energy.

An imaging game card device, comprising receiving means;
- a card, comprising:
- a substrate imprinted with a pattern of infrared radiating ink;
- and
- a thermal sensitive layer deposited over said substrate to visually conceal the ink prior to said card being inserted into said receiving means;
- and
- a light source, comprising:
- a source of electrical energy;
- a flash tube generating light in response to said electrical energy;
- and
- means for adjusting the electrical energy in response to light generation of the flash tube.
