Abstract: A method and apparatus for assembling an inkjet printhead is disclosed. The apparatus comprises one or more microheater resistors and a material, which can be reflowed by use of the heat generated by the microheater, disposed proximate to the heater resistor. The microheater resistor comprises a heater resistor with an input port and an output port. A first electrical conductor, coupled to the input port of the heater resistor, receives a first voltage and a second electrical conductor, coupled to the output port of the heater resistor, receives a second voltage. A curing effect in the adhesive is produced by heat generated in the heater resistor when electrical current flows through the resistor in response to an application of a first voltage to the first electrical conductor and a second voltage to the second electrical conductor.

Abstract: An optical arrangement in a laser scanner for generating a cross bar X laser light beam scan pattern includes a multi-faceted or -mirrored optical device mounted for rotation about a vertical axis. The device has four primary mirrors oriented ninety degrees from one to the next about the vertical axis. The primary mirrors are tilted about respective horizontal axes relative to the vertical axis and adapted to receive and reflect a laser light beam as each primary mirror moves successively through a portion of each rotational cycle of the optical device. The optical arrangement also includes a multiplicity of secondary mirrors disposed in stationary positions relative to one another and to each of the primary mirrors as they move successively through the rotational cycle portion.

Abstract: A compact counter-type bar code scanner produces a "five-apparent-source" scan geometry within an optimum scan volume above the deck of the bar code reader, with a total scanner housing height of less than 13 centimeters, and preferably about 11.5 centimeters. The optics are maximized to achieve approximately the same bar code reading efficiency and reliability as in previous much deeper bar code scanners producing similar scan geometry by reflecting the scanned beam off three surfaces, the last of which is horizontal.

Abstract: A laser scanner having a rotating mirror, such as a POS scanner as used in supermarkets, uses a closed-loop velocity controlled DC brushless motor for rotating the mirror. In addition to providing a hall effect motor speed signal which is used for monitoring and safety features in association with the scanner, the DC brushless motor provides the advantages of greatly reduced power consumption, decreased temperature rise, less electrical noise in the analog scanner circuitry, reduced cost, and greatly reduced size, sometimes over 80%. The use of the inherent motor speed signal from the DC brushless motor also enables elimination of costly mechanical windswitches as typically used in prior scanners.

Abstract: A laser instrument of the kind used to read or to detect light reflected from a target which is spaced from the laser instrument comprises a laser for generating a laser beam for transmission to the target, and a detector for detecting light reflected from the target and a trifocal, composite, single piece lens system. The trifocal lens system receives the laser beam from the laser at an angle which is off the optical axis of the lens system, routes the received laser beam onto the optical axis for transmission through the lens system and toward the target, collects light reflected from the target and images and transmits the collected light along the optical axis to the detector means. In a specific embodiment of the invention the trifocal, composite, single piece lens system is a plastic molded structure.
