Abstract: In a system and a method for calibrating turn-on energy of a fluid-ejecting marking device, a reference object and a plurality of test objects are contemporaneously printed by the marking device on a same type of substrate. The reference object is printed at a known “on” voltage at a first pattern density, and the test objects are printed at a series of decrementing voltages at an intended second pattern density greater than the first pattern density. A scanning device compares the reference object to the test objects to determine which test object(s) most closely resemble(s) the reference object. Based at least upon this comparison, a turn-on energy for the marking device is determined. By using a reference object to compare the test objects to, a turn-on energy can be calculated independent of the type of substrate used and the ambient conditions present when printing the reference and test objects.

Abstract: An inkjet printhead with a nozzle plate that has an exterior surface with formations for reducing its co-efficient of static friction. By reducing the co-efficient of static friction, there is less likelihood that paper dust or other contaminants will clog the nozzles in the nozzle plate. Static friction, or “stiction” as it has become known, allows dust particles to “stick” to nozzle plates and thereby clog nozzles. By patterning the exterior of the nozzle plate with raised formations, dust particles can only contact the outer extremities of each formation. This reduces friction between the particles and the nozzle plate so that any particles that contact the plate are less likely to attach, and if they do attach, they are more likely to be removed by printhead maintenance cleaning cycles.

Abstract: A system for diagnostically evaluating the health of tissue within the fundus of an eye includes a fs laser source, an adaptive optical assembly, an imaging unit, and a computer. The adaptive optical assembly focuses a laser beam to a focal point in the fundus of the eye, and scans the fundus tissue according to a predetermined scanning pattern.

Red photons, with a wavelength (?) of about 880 nm, are converted to blue photons, with a wavelength of ?/2, through the process of photon conversion. An imaging unit senses the blue photon return light, and uses the return light to generate an image of the fundus. The computer processes the image, and compares it to a template of healthy tissue to evaluate the health of the imaged tissue.

Abstract: Described herein are display devices that provide projection-type video output and use redundant sets of lasers to generate light. The laser set produces a desired amount of light, e.g., for a primary color. A redundant laser set includes more lasers than that needed to produce the desired amount of light. For example, a set of six lasers may only need five lasers to generate and emit a desired amount of light. The sixth laser allows failure of one laser in the set to not compromise operability of the entire set—and the display device. In addition, extra lasers in a laser set also allows the lasers to be cycled for heat purposes and to extend longevity of individual lasers in the set.
