摘要： A micro-fluid ejection head has multiple ejection chips joined adjacently to create a lengthy array across a media to-be-imaged. The chips have fluid firing elements arranged along skewed fluid vias to enable seamless stitching of fluid ejections. The firing elements are energized to eject fluid and ones are spaced according to colors or fluid types. Overlapping firing elements serve redundancy efforts during imaging for reliable print quality. Variable chips sizes and shapes are disclosed as are relationships between differently colored fluid vias. Skew angles range variously each with noted advantages. Singulating chips from larger wafers provide still further embodiments.

摘要： A method of characterizing a wiring network is implemented in a system which includes a test controller and at least two probes. On commands from the test controller, at least one of the probes changes its impedance between the nominal impedance of the wiring network and a mismatch impedance. Reflectometry measurements are performed before and after of switching the impedance of the second probe. At the first probe, an RF signal is generated and a reflected signal is measured. Then, the impedance of the second probe is changed, and again an RF signal is generated and a reflected signal is measured at the first probe. Additionally, a frequency response may be measured at the second probe. The results of the measurements are used for characterization of a transmission line between the first and second probes.

摘要： An ink manifold constructed with a number of semiconductor tiles which are fastened end to end on a rigid base member to form a page wide print mechanism. Each tile is constructed with ink channels on one side in liquid communication with ink outlet ports on the opposite side. The ink channels carry ink from ports in the base member to the outlet ports of the tiles. The interface between each tile defines a boundary. An inkjet printhead is fastened over each boundary of the tiled manifold so that the ink inlet ports of the printhead are aligned with the ink outlet ports of the underlying tiles. No ink passes across the boundary of the adjacent manifold tiles. The fabrication of the individual tiles from a semiconductor wafer facilitates usage of the wafer when fabricating page wide print mechanisms.

摘要： In order to measure the performance of a DOCSIS upstream channel as well as to locate impairments, a special test signal is transmitted in a time slot of the upstream channel by a test instrument positioned anywhere within the CATV plant. A second test instrument, located at the termination point of the upstream plant, then detects, recovers, and processes the test signal in order to complete the measurement. The typical methods used to detect and recover bursted signals within a DOCSIS upstream channel use precise timing information transmitted in a corresponding DOCSIS downstream channel. Unfortunately, the downstream channel and thus the precise timing information are not always available to the secondary test instrument. The present invention also describes an apparatus and method for detecting a bursted test signal without the use of the DOCSIS upstream channel timing.

The surface inspection system includes a beam source subsystem, a beam scanning subsystem, a workpiece movement subsystem, an optical collection and detection subsystem, and a processing subsystem. The system features a variable scan speed beam scanning subsystem, preferably using an acousto-optic deflector, with beam compensation, so that variable scanning speeds can be achieved. Also included are methods and systems for improving the signal to noise ratio by use of scatter reducing complements, and a system and method for selectively and repeatedly scanning a region of interest on the surface in order to provide additional observations of the region of interest.
