摘要： In one embodiment, a drop ejector assembly includes a printhead, a drop zone immediately downstream from the printhead, an array of optical fibers exposed to the drop zone such that light scattered off drops in the drop zone illuminates at least some of the optical fibers in the array, and a photo detector operatively connected to the array of optical fibers for converting light from the optical fibers into an electrical signal. In another embodiment, a drop detector includes a light source for illuminating drops passing through a drop zone and a light sensor for sensing light scattered off drops in the drop zone. The length of drop zone is 3 mm or less and the light sensor has a cross sectional dimension less than the length of the drop zone.

摘要： An apparatus includes micro-electromechanical (MEM) devices, a charge source, and a discharge mechanism. Each MEM device has different states based on a charged induced thereon. The charge source is to induce the charge thereon such that the MEM devices each enter one of the different states thereof. The discharge mechanism for the MEM devices is to discharge the induced thereon. The discharge mechanism includes one of a resistor for each MEM device and an ultraviolet (UV) light source. The resistor is to discharge the charge on its MEM device to ground. The UV light source is to emit photons onto the MEM devices, such that the photons discharge the charge on the MEM devices via photoelectric effect.

摘要： A display system includes a housing having at least one optical window and at least one charge-controlled spatial light-modulator disposed within the housing. The at least one spatial light-modulator is configured to project an image-bearing light beam to a viewing surface through the at least one optical window. The system further includes at least one electron gun selectively positioned at a predetermined angle with respect to the at least one spatial light-modulator. The electron gun is configured to project an electron beam into the housing to impinge a front surface of the at least one spatial light-modulator.
