A medium for displaying information thereon, the medium includes a substrate; and visible information formed from a plurality of colors displayed on the substrate; wherein at least one of the colors includes at least one visible colorant and at least one invisible colorant which invisible colorant is imperceptible to the human eye and which is not present in a reproduction therefrom for detecting counterfeiting or forgery.
摘要:
A light modulator for modulating a beam of light of wavelength .lambda. including a substrate, a fixed electrode formed over the substrate and arranged to reflect light; an insulative transparent layer defining a modulating region formed over the fixed electrode wherein the height of the insulative transparent layer is substantially an odd multiple of .lambda./n4, where n is the refractive index of the insulative transparent layer; the plurality of electrodes having a coiled portion disposed adjacent to the modulating region and effective in a first configuration wherein the coiled portion remains coiled and in a second flat configuration in response to a voltage applied between the plurality of electrodes and the fixed electrode for uncoiling the coiled portion so that it is in the second flat configuration over the modulating region; a top surface of the plurality of electrodes being made of a reflective material; and applying a voltage across the plurality of electrodes and the fixed electrode to uncoil the coiled portion so that it is in the second flat configuration and its top surface is arranged to reflect light illuminating the modulating region so that light reflected from the top surface of the plurality of electrodes interferes with the light reflected from the fixed electrode to modulate the light which illuminates the light modulating region.
摘要:
Electrographic printing apparatus for forming a toner image on a recording medium includes: a magnetic brush having a rotatable magnetic core and a stationary outer shell; a developer supply for supplying a magnetic developer powder to the magnetic brush; a print head on the outer shell; and a receiver electrode arranged in spaced relation to the print head to define a recording region through which the receiver can be moved. The print head includes an array of microchannels for forming a plurality of parallel lines of developer in the channels, a corresponding plurality of transfer electrodes located in the microchannels for selectively transferring developer from the lines to a receiver, driver circuitry for generating and applying transfer signals to the transfer electrodes, a power supply connection for applying power to the drive circuitry, a print signal input connection for applying print signals to the print head, the print signal input including a number of electrical conductors fewer than the number of transfer electrodes, and a logic and control circuit for applying the print signals to the drive circuitry.
摘要:
A camera for recognizing voice commands, and for visually displaying an image to be captured by the camera with camera operations performed thereon as instructed by the voice commands, the camera comprises a camera body; a microphone disposed on the camera body for inputting voice commands; a controller disposed in the camera body for receiving and recognizing voice commands, and for implementing results of the voice command; and a display attached to the camera body for visually displaying the image to-be-captured by the camera with the camera operations performed thereon as instructed by the voice commands.
摘要:
A touch sensitive electronic switch for a camera comprises a pair of front and rear cover parts of the camera that constitute separate electrical conductors which when temporarily bridged by one's hand allow a direct current path between the front and rear cover parts, and an insulator configured to fill a space between the front and rear cover parts in order that the front and rear cover parts and the insulator together define a housing for the camera.
摘要:
An electrographic printer includes: a magnetic brush having a stationary outer shell and a rotating multi-pole magnet within the outer shell; an electrographic print head mounted on the outer shell of the magnetic brush; a Hall effect sensor located adjacent to the magnetic brush for detecting a field produced by the multi-pole magnet parallel to the surface of the shell and producing an output signal; and a pulse control circuit connected to the Hall effect sensor for detecting zero crossings of the output signal and supplying printing pulses to the electrographic print head in response thereto.
摘要:
A method for manufacturing a multi-faceted polygon for a laser writer, comprises the steps of creating a plurality of scanning surfaces on the polygon; and creating a step which is positioned on a mounting surface of the polygon for indicating the center of rotation for the polygon.
摘要:
An electronically actuated shutter in which the location of the shutter blades are known to accurately control the aperture opening and exposure time. A Hall sensor is used to determine the position of the shutter blades.
