摘要： A method and apparatus for correcting for drop placement errors due to relative rotation between an inkjet printhead mounted in a printer carriage and the print media to be printed on comprises first determining the relative contribution to the drop placement error due to rotation of the printhead about the scan axis (Y axis error), then, with respect to any determined Y axis error, applying the same magnitude and sense of correction for drop placement errors while printing in both a first scanning direction of the carriage and while printing in a second scanning direction of the carriage. Errors due to rotation about the Z axis are also corrected for. Preferably the errors are determined by printing and scanning a test pattern.

摘要： A misalignment compensation technique for a dot printer is disclosed. This technique first supplies printing instructions to a printhead for energizing printing elements in various groups (primitives) to print a pattern on a medium. The printed pattern is then detected by optical sensors in the printer. Based on the detection, a position offset error for each primitive is determined. These errors are used to generate a separate time correction for each of the primitives such that, when the printer is used normally, the time period for printing a dot will be advanced or delayed for each primitive so as to align the dots printed by the primitives. In another embodiment, alignment data taken by a manufacturing line sensor is stored in a memory on the print cartridge. After the print cartridge is installed in the printer, a second optical test completes the data needed to create timing correction values.
摘要翻译：公开了一种点打印机的对准补偿技术。该技术首先将打印指令提供给打印头，用于激励各种组（原始图案）中的打印元件以在介质上打印图案。然后通过打印机中的光学传感器检测印刷图案。基于检测，确定每个图元的位置偏移误差。这些错误用于为每个图元生成单独的时间校正，使得当正常使用打印机时，对于每个图元，打印点的时间段将被提前或延迟，以便对准由图元打印的点。在另一个实施例中，由生产线传感器获取的对准数据被存储在打印盒上的存储器中。打印墨盒安装在打印机中后，第二次光学测试完成创建定时校正值所需的数据。

摘要： Described is a process for forming an LED structure using a laser lift-off process to remove the growth substrate (e.g., sapphire) after the LED die is bonded to a submount. The underside of the LED die has formed on it anode and cathode electrodes that are substantially in the same plane, where the electrodes cover at least 85% of the back surface of the LED structure. The submount has a corresponding layout of anode and cathode electrodes substantially in the same plane. The LED die electrodes and submount electrodes are ultrasonically welded together such that virtually the entire surface of the LED die is supported by the electrodes and submount. Other bonding techniques may also be used. No underfill is used. The growth substrate, forming the top of the LED structure, is then removed from the LED layers using a laser lift-off process. The extremely high pressures created during the laser lift-off process do not damage the LED layers due to the large area support of the LED layers by the electrodes and submount.

In some embodiments, the compliant bonding structure is plurality of metal bumps that undergo plastic deformation during bonding.

摘要： A process for forming electrical contacts for a semiconductor light emitting apparatus is disclosed. The light emitting apparatus has a first layer of first conductivity type, an active layer for generating light overlying the first layer, and a second layer of second conductivity type overlying the active layer. The process involves forming at least a first and a second elongate electrical contact through the second layer and the active layer to provide electrical connection to the first layer, the first and second contacts oriented at an angle to each other, the first contact having a first end in proximity with the second contact, the first end being sufficiently spaced apart from the second contact such that when current is supplied to the first layer through the contacts, current contributions from the first end of the first contact and the second contact in an area generally between the first end and the second contact cause a current density in the area that is approximately equal to a current density elsewhere along the first and second contacts

摘要： A bubble valve that comprises a liquid delivery channel and a localized heating arrangement. The liquid delivery channel includes an upstream portion and a constriction downstream of the upstream portion. The constriction has a smaller cross-sectional area than the upstream portion. The localized heating arrangement is located in the liquid delivery channel and generates heat to nucleate and enlarge a bubble in the liquid. The constriction is shaped to form a seal with the bubble. The localized heating arrangement additionally generates heat to move the bubble relative to the constriction to control the flow of the liquid. A pressure regulator that comprises a liquid delivery channel connected to a liquid outlet, a sensor located adjacent the liquid outlet, a controller that operates in response to the sensor and a localized heating arrangement. The liquid delivery channel includes an upstream portion, and a constriction located between the upstream portion and the liquid outlet. The constriction has a smaller cross-sectional area than the upstream portion. The localized heating arrangement is located in the liquid delivery channel and generates heat in response to the controller to nucleate and enlarge a bubble in the liquid. The constriction is shaped to form a seal with the bubble. The localized heating arrangement additionally generates heat to move the bubble relative to the constriction to control the flow of the liquid to the liquid outlet.

摘要： Flexible printed circuit boards interconnect to adjacent electronic devices through one or more of high speed data, low speed data, high current, and ground lines and pads. The design of the high speed data pads and traces and adjacent ground pads and traces maintains a desired impedance in the flexible circuit and at the transition from the flexible circuit to a printed circuit board, a ceramic header, or other device to ensure high speed operation. The pads are preferably arranged in a two dimensional geometry such that a connecting area of the flexible circuit is narrower than it would preferably be if the pads were arranged linearly. The two dimensional array also allows the use of the high current thermoelectric cooler pads, which require large surface areas that may otherwise not fit in a conventional linear array.

摘要： A receive optical subassembly comprises a header assembly positioned inside an outer shell that interfaces with a receive optical fiber. The header assembly comprises an upper surface upon which one or more optical components can be mounted, the upper surface defined at least in party by a standard plane. The header assembly further comprises an angled surface that is angled with respect to the standard plane. The angled surface can comprise, for example, a sloped cavity stamped inside the header assembly, or an angled shim positioned on top of the header assembly upper surface. An optical receiver mounted on the angled surface receives an incoming optical signal but reflects at least a portion of stray optical signals away from the incoming optical signal.
