摘要： An improved waveguide shuttle optical switch design which provides the function of a variable optical attenuator (VOA). A small degree of intentional misalignment of the waveguide will create different levels of optical attenuation. By finely controlling the misalignment of a selected switched position, a single device may be realized that will provide the functions of both switching and attenuating or just attenuation alone. The optical MEMS device utilizes a latching mechanism in association with a thermal drive actuator for aligning a waveguide shuttle platform. The integration of the switching function and the VOA function reduce the optical loss which is otherwise unavoidable when the inevitable alternative of a separate switch and a separate VOA must necessarily be employed. The resultant improved device can also be applied for correcting the difference in optical intensity created by the manufacturing tolerances inherent in the fabrication of array waveguide gratings.

摘要： In a printing system in which the print media sheets are alternately fed from the same stack in the same tray by two sheet feeders at opposite sides into different sheet paths, at least one of the sheet feeders is repositionable towards and away from the other for feeding different size sheets, and the connecting sheet path is repositionable with the repositioning of the sheet feeder. The repositioning of the sheet feeder and its associated sheet path may be automatic in coordination with the normal resetting of a tray stack edge guide with the loading of different size sheets into the tray. The enhanced rate sheet feeding may be for a dual print engine printing system and/or selectably common or reversed sheet facing. Alternating coordinated lifting of a nudger roll of one sheet feeder with operation of the opposing sheet feeder, and retard nips spaced from the stack, may be provided.

摘要： A vent connects a chamber to the external atmosphere surrounding a device to equalize pressure within the chamber. The vent has a size and shape to allow pressure equalization to occur outside a normal operating cycle of the chamber and controls the pressure to prevent undesirable deflection of a membrane within the chamber and ensure proper operation of the device.

摘要： An optical switch for routing signals includes a latch receiver connected to a waveguide that routes the signals and an actuator that includes an upper plate, a lower plate and a latch connected to the lower plate, the lower plate of the actuator moving vertically when power is applied to the lower plate, causing the latch to move vertically and engage the latch receiver. A latching system includes a switch that includes a latch formed to include an extension on one end of the latch, the latch being driven by power, a latch receiver that is formed to receive the latch and a controller that controls the extension of the latch to engage the latch receiver when the power is applied to the latch, and controls the extension of the latch to lock in place against the latch receiver when the power is removed from the latch.
