Metal is reserved in intervening metal layers within a clock driver block between the clock driver input line and the input of a first one of said plurality of clock buffers in the variable clock buffer chain. Metal is reserved on one or more metal layers for connecting the output of each of the clock buffers in the clock buffer chain to the clock driver output line. The metal layers are partitioned into one or more programming layers and one or more non-programming layers.

Abstract: A method and apparatus for interpolating color image information are provided. One or more image data values for a portion of a digital image in a vicinity of a target pixel are received and stored in a local array. A processor determines whether there is an edge in the vicinity of the target pixel based on the data values in the local array. If there is not an edge in the vicinity of the target pixel, then long scale interpolation is performed on the image data values in the local array, in order to result in interpolating color information that is missing from the image. If there is an edge in the vicinity of the target pixel, then short scale interpolation is performed using image data values in a subset of the local array in a closer vicinity of the target pixel. As a result, accurate color rendering of a digital image is achieved, even in the presence of an edge portion that exhibits great contrast between regions of the image.

Abstract: A system is disclosed for manipulating buses and signals on a display window of a graphical user interface of a logic analyzer. Each signal is associated on the display with representations of its sampled data, which may be in the form of lists or of waveforms. The system enables a user to graphically associate the buses and signals. Also, the buses and signals may be visually associated on the display window with user-specified trigger-conditions. The User may graphically associate the signals into buses by selecting the signals then grouping them by selecting a group command. Responsive to this grouping, the system may generate a bus representing the grouped signals. The bus may be graphically associated with the grouped signal-name elements, such as, for example, by a hierarchical structure. The system, responsive to the grouping by the user of the signals into buses, generates bus-data elements representing signal data associated with the grouped signals.

Abstract: A bubble optical switch includes a switching chamber, a static bubble drum, and a quenching pipe. The static bubble drum is adapted to contain a static bubble. In the inactive state, the static bubble remains within the static bubble drum and the switching chamber is filled with index matching fluid. To activate the switch, heat is introduced expanding the static bubble into the switching chamber displacing the index matching fluid with vapor. Then, the optical signal is reflected from the wall of the switching chamber. When the heat is removed, the static bubble contracts back into the static bubble drum. Because the temperature required to expand the static bubble is lower than the temperature required to nucleate a bubble from the fluid, the reliability and lifetime of the switch is increased. Further, due to the properties of the contracting static bubble, no residual bubble forms, thereby alleviating problems associated with residual bubbles of the prior art bubble switches.

Abstract: A method of fabricating nanosized holes with controlled geometries employs tools and methods developed in the microelectronics industry. The method exploits the fact that epitaxially grown film thicknesses can be controlled within a few atomic monolayers and that by using etching techniques, trenches and channels can be created that are only a few nanometers wide. The method involves bonding two shallow channels at an angle such that a nanopore is defined by the intersection. Thus, a nanopore-defining device includes a nanopore with dimensions that are determined by the dimensions and orientations of the intersecting channels, with the dimensions being accurately controlled within a few monolayers.

An embodiment includes using a reflective surface on the interface also for viewing the target and, e.g., by means of signals from a processor, adjusting the relative position of the target substrate and the laser beam. The apparatus can also be operated at pressures that are less than or greater than atmospheric.

Abstract: A biochemical assay device optically scans individual biological sample containing wells in an assay plate. The device includes an imaging system overlaying the assay plate wherein a scanning light propagates by total internal reflection within an optical waveguide. The waveguide includes a plurality of pixel locations, each aligned with a well in the assay plate, at which total internal reflection is selectively frustrated to output an incident beam of light. That light illuminates the well and causes generation of an emission beam of light that is detected by a photoreceptor. The device further includes a driver circuit that controls the selective frustration of total internal reflection at each pixel location in order to scan each well in the assay plate. A processor is also included in the device to process the detected emission beams of light generated by the scanned wells for purposes of assaying the biological sample contained in each scanned well.

Abstract: A method and apparatus are provided for determining quality metrics associated with a test pattern used to test an integrated circuit (IC). The delays associated with (1) a longest sensitizable path through the IC that includes the delay fault and (2) an actual path exercised by the test pattern through the IC that includes the delay fault are determined. A difference between the delays is then obtained. The difference is then combined with a difference between a speed at which the test is performed and a design specification operating speed of the IC for the actual path. The sum represents the first quality metric associated with the test pattern for a given fault site. The ratio of the delays of the actual path to the longest sensitizable path represents the second quality metric associated with the test pattern for a given fault site.

Abstract: A high dynamic range receiver includes a detector that produces a current at a pair of terminals. A first gain element, implemented as a current-to-voltage converter for example, is coupled to the first terminal, receiving the current and generating a first output signal corresponding to the current. A second gain element, implemented as a current-to-voltage converter for example, is coupled to the second terminal, receiving the current and generating a second output signal corresponding to the received current. A switch selectively couples the first output signal or the second output signal to a port based on a comparison of at least one of the first output signal and the second output signal to a threshold.
