Abstract: An image sensor system and methods of making such a system are described. The image sensor system includes a color filter array that is formed by a color filter process that incorporates a bottom antireflection coating. The bottom antireflection coating forms a protective layer that protects exposed areas of the active image sensing device structure during formation of the color filter array and, thereby, preserves the intrinsic transmission characteristics of the active image sensing device structure. The bottom antireflection coating also reduces degradation of metal structures (e.g., bonding pads) and pixel edges at the exposed surface of the active image sensing device structure. In addition, the bottom antireflection coating provides a reliable adhesive surface for the color filter array, substantially eliminating lifting of the color filter array resist structures.

Abstract: An x-ray laminography imaging system that utilizes a nonplanar anode target to enable objects that are oblique to the direction of projection of electron beams onto the target to be precisely imaged. Because many objects that laminography techniques are used to inspect are oblique or have portions that are oblique, the nonplanar anode target of the present invention enables enables spot patterns to be traced that are parallel to the plane of the object, regardless of whether it is oblique or orthogonal.

Abstract: Liquid metal microrelays may be made where a contact is formed by constraining a quantity of liquid metal at the end of a contact support suspended over a substrate. Movement of the contact support typically drags the liquid metal along the surface of the substrate and allows the liquid metal to bridge contacts located on the substrate. Coplanar waveguides may be used for the switched signal instead of microstrip transmission lines to reduce transmission line discontinuities due to impedance changes.

Abstract: The present invention teaches an apparatus for testing the circuitry in an input/output (I/O) pad without probing the contact site on the I/O pad. A dominant driving circuit has an output coupled to a first contact site on a semiconductor chip. A subordinate driving circuit also has an output coupled to the first contact site on the semiconductor chip. A test control circuit sets a drive fight up between the dominant and subordinate driving circuits, the test control circuit selecting a stronger drive strength for the dominant driving circuit than for the subordinate driving circuit. The drive fight produces a test value at the first contact site. The test value from the first contact site is transferred to a second contact site on the semiconductor chip to be probed by an external prober.

Abstract: A system and method for reducing unnecessary alert messages is achieved by allowing a user agent to store alert, and alert update, messages in storage remote from the alert generation system. Typically, these alerts would come from a central source, such as a rule engine. Without local storage of prior alerts, the rule engine would have to generate new alerts for each new user entering the system.

Abstract: A filter for injecting data dependent jitter and level noise into a digital data signal with a given data rate reacts on a step function with a step response showing after a first increase or decrease a substantial extreme value, such as a minimum or a maximum, of opposite direction than the first increase or decrease. The temporal occurrence of the substantial extreme value with respect to the step function is substantially in the range of the given data rate.

Abstract: A polarization control system includes a beam source that generates a first beam component containing light with a first polarization and a first frequency and a second beam component containing light with a second polarization and a second frequency. A polarization state modulator adjusts the polarizations of the components for transmission on a single optical fiber. A detector system measures polarizations of the components when output from the optical fiber and determines how to adjust the polarization state modulator in order to give the first and the second components the desired output polarization states. The beam source can be implemented using a Zeeman-split laser, a laser containing a birefringent element, a pair of phase-locked lasers, and/or a variety of configurations of electro-optic or acousto-optic crystals operated to create or enhance the frequency difference between the beam components.

Abstract: A test system that includes a generator and an analyzer acting cooperatively to test a device having a plurality of device communication channels. The device has a plurality of inputs and corresponding outputs, each input being connected to a corresponding one of the outputs. The correspondence between the input and output channels may change if the device is turned off and on or if the device is not actively sending data from the inputs to the outputs. The test system determines a mapping between the device inputs and outputs prior to performing bit error rate testing utilizing a mapping test pattern. The test system can then switch to a bit error rate test pattern without causing the device to drift such that the correspondence between the input and output channels is lost.

Abstract: A polarization control system includes a light source that generates two light beams with different polarization states and optical frequencies. A polarization state modulator changes the polarization states of the two light beams. Three detector paths generate a first beat signal, a second beat signal, and a third beat signal from the two light beams. An amplitude detector determines the amplitude of the first beat signal at a beat frequency. A phase comparator determines the phase difference between the second and the third beat signals. The system then uses the amplitude and the phase difference to determine how to adjust the polarization state modulator in order to generate the first and the second light beams with the desired polarization states.

A second plurality of stages each support a ferrule surrounding an end portion of a corresponding one of M optical output fibers. Mechanical mechanisms translate the stages along a plurality of orthogonal X and Y axes to align a facet of a selected one of the N input optical fibers with a facet of a selected one of the M output optical fibers. The stages of the input optical fibers, the output optical fibers, or both, have mechanical mechanisms for moving the ferrules along Z axes perpendicular to the X and Y axes into and out of alignment holes of a central panel to physically mate the facets of the coupled fibers.

The contacts are also coupled to a test sensor port via a second plurality of passive circuit components, ones of which are coupled in parallel to the test sensor port. The method proceeds with stimulating one or more nodes of the connector, and then measuring an electrical characteristic via the test sensor port. Finally, the measured electrical characteristic is compared to at least one threshold to assess continuities of at least two electrical paths through the connector.

Abstract: An electrical circuit generates an oscillating signal that produces reduced electromagnetic interference by way of modulation of the frequency of the oscillating signal within a specified frequency range. A randomized signal generator creates a randomized signal, which is then used to drive a frequency range converter that is employed to produce a frequency modulation signal. The current state of the frequency modulation signal is based on the current state of the randomized signal, with the converter limiting the current state of the frequency modulation signal so that the oscillating signal will only operate within the specified frequency range. A variable frequency oscillator then generates the oscillating signal whose frequency is based on the current state of the frequency modulation signal.

Abstract: A digital oscilloscope assists in the process of identifying, cataloging and restoring views of interest within a stored trace acquisition by implementing the notion of bookmarks. In response to a command to establish a bookmark, the scope takes note of selected display control parameters, such as the location of the view in the overall acquired trace and horizontal time per division, and stores that as a named bookmark. The scope accepts from the operator a comment associated with each bookmark. Another command lists defined bookmarks and causes the scope to re-institute the view and parameters associated with a specified bookmark. There is a mechanism for editing the descriptors or parameters that are defined by a bookmark.
