Illuminated display with simulated motion
Patent 7,926,211
The invention is directed toward a decorative apparatus for presenting visual images having the appearance of motion constructed of a front panel picture member mounted to a rear panel housing. The front panel picture member is a rectangular [private]glass pane painted on the front face to define a transparent window and a translucent photographic picture mounted on a rear face of the planar member and framed by a border painted on the front face. The rear panel housing has a drive motor mounted to the housing which is connected to a rotatable driving roller which is also mounted to the housing. A driven roller is mounted to the housing oriented parallel to driving roller with an endless loop of transparent film having random designs applied thereon engaging the rollers. A stationary blocking screen is mounted to the housing in front of the endless loop, the blocking screen defining transparent sections with undulating designs and opaque sections; and a light source mounted in the panel housing behind the endless loop of film to illuminate the loop of endless film and the photographic picture.

Group III-nitride growth on silicon or silicon germanium substrates and method and devices therefor
Patent 7,928,471
A structure including a Si.sub.1-xGe.sub.x substrate and a distributed Bragg reflector layer disposed directly onto the substrate. The distributed Bragg reflector layer includes a repeating pattern that includes at least one aluminum nitride layer and a second layer having the general formula Al.sub.yGa.sub.1-yN. Another aspect of the present invention is various devices including this structure. Another aspect of the present invention is directed to a method of forming such a structure comprising providing a Si.sub.1-xGe.sub.x substrate and depositing a distributed Bragg reflector layer directly onto the substrate. Another aspect of the present invention is directed to a photodetector or photovoltaic cell device, including a Si.sub.1-xGe.sub.x substrate device, a group III-nitride device and contacts to provide a conductive path for a current generated across at least one of the Si.sub.1-xGe.sub.x substrate device and the group III-nitride device upon incident light.

Electroblowing web formation
Patent 7,931,456
An improved electroblowing process is provided for forming a fibrous web of nanofibers wherein polymer stream is issued from a spinning nozzle in a spinneret with the aid of a forwarding gas stream, passes an electrode and a resulting nanofiber web is collected on a collector. The process includes applying a high voltage to the electrode and grounding the spinneret such that an electric field is generated between the spinneret and the electrode of sufficient strength to impart an electrical charge on the polymer as it issues from the spinning nozzle.

Systems and methods for detecting and monitoring nickel-silicide process and induced failures
Patent 7,932,105
Systems and methods for detecting and monitoring Nickel-silicide process and induced failures. In a first method embodiment, a method of characterizing a Nickel-silicide semiconductor manufacturing process includes accessing a test chip including a parallel coupled chain of transistors, wherein the transistors are designed for inducing stress into Nickel-silicide features of the transistors, and for increasing a probability of a manufacturing failure of the Nickel-silicide features. A biasing voltage is applied to one terminal of the parallel coupled chain, all other terminals of the parallel coupled chain and grounded, and current is measured at each of the all other terminals of the parallel coupled chain. This process is repeated for each terminal of the parallel coupled chain. The measured currents from all possible conduction paths are compared to determine a manufacturing defect in the parallel coupled chain of transistors.
