摘要： A vehicle cylinder head coolant passage inspection device and a method for inspecting vehicle cylinder head coolant passages therewith. A device and method of the present invention can be used to detect blockages present within such coolant passages. A device and method of the present invention uses one or more fiber-optic probes that can both emit and receive light. The probe(s) are used with a sensor that can register light reflected by a blockage and received by a probe(s) while in a coolant passage. Reflected light readings registered by the sensor can be used to determine whether a blockage is present.

摘要： First and second substrates are spaced apart and joined around a perimeter to define a gas chamber between the substrates. The first substrate is made of a material that transmits visible radiation. A layer of a phosphor material overlies an interior surface of one of the substrates and is capable of converting UV radiation to visible radiation. A layer of a reflective material overlies an interior surface of the other one of the substrates.

摘要： A universal fixture for testing a device, such as a bare printed circuit board, includes a plurality of addressable contact points. Each of the contact points includes a switch connected to a conductor capable of creating an electrical connection to the device. To obtain a measurement of a target on the device, two of the contact points on the universal fixture are selected based on the position of the target on the device relative to the contact points.

摘要： A spatial light modulator for use in a photolithography system includes light modulation elements configured to photolithographically transfer an image onto a substrate using an optical oversampling technique to reduce defects in the transferred image. A first set of the light modulation elements is operable to photolithographically transfer a portion of the image onto an area of a substrate, and a second set of the light modulation elements is operable to photolithographically transfer the portion of the image onto the area of the substrate. The spatial light modulator further includes memory elements in communication with respective light modulation elements for storing data representing the portion of the image.

摘要： Embodiments of the invention involve UV resistant liquid crystal cells. One embodiment of the invention is to increase the volume of the liquid crystal material that is stored inside the cell. For example, trenches may be used to provide reservoirs that hold the additional liquid crystal material. Another embodiment of the invention uses an inorganic alignment layer in the cell, instead of using an organic material as the alignment layer. A further embodiment of the invention uses a pump to circulate liquid crystal material through the cell. The inventive cell can be used as a SLM in photolithographic imaging systems.

摘要： A wavelength selective switching device and method for selectively transmitting optical signals based on wavelength utilizes diffraction to spatially separate the optical signals of different wavelengths such that the optical signal of a selected wavelength can be selectively transmitted. The wavelength selective switching device selectively rotates the polarization components of the optical signals such that the polarization states of the polarization components are the same in both incoming and outgoing directions at the diffraction grating. Thus, a diffraction grating with a high grating line frequency (e.g. greater than 900 grating lines per mm for signals in the 1550 nm wavelength range) can be used for diffracting the polarization components of the optical signals in both the incoming and outgoing directions.

摘要： Display contrast in electro-optical display devices is improved using a drive circuit including pixel drive circuits and a common drive circuit. The pixel drive circuits are connected to pixel electrodes of the display device, and are operable to generate respective pixel drive signals that alternate between a first high voltage and a first low voltage differing in voltage by less than or equal to a process-limited maximum. The common drive circuit is connected to a common electrode of the display device, and is operable to generate a common drive signal alternating between a second high voltage and a second low voltage differing in voltage by more than the process-limited maximum. The common drive signal is asymmetrically bipolar with respect to the first low voltage of the pixel drive signal.
