20090025479METHOD AND APPARATUS FOR QUANTIFYING POROSITY IN A COMPONENT - A computer implemented method, or hardware filtration apparatus, and computer usable program code for measuring porosity in materials. An ultrasonic signal is emitted from a transmitting transducer in an ultrasonic measurement system into a material. A response signal is received at a receiving transducer in the ultrasonic measurement system from the material. The response signal is filtered to pass only frequencies in the response signal within a selected frequency range to form a filtered response signal. A porosity level of the material is identified using the filtered response signal.01-29-2009

20100064812ULTRASONIC PROBE - An ultrasonic probe includes a probe body having a contact surface and a cavity that is open at the contact surface, an ultrasonic transducer carried by the body, and a spacer within the cavity. The spacer has a first surface acoustically coupled to the transducer, and a second (coupling) surface within the cavity. The spacer propagates an acoustic signal between the transducer and the coupling surface. The coupling surface is spaced apart from the contact surface to form a recess within the body. The body further has at least one port for circulating a coupling fluid into the recess. Depth of the recess is selected to balance gravitational force on the coupling fluid versus surface tension of the coupling fluid so a bead of the fluid forms over an edge of a structure under inspection as the probe is moved over the edge.03-18-2010

20100229930HIGHLY DOPED LAYER FOR TUNNEL JUNCTIONS IN SOLAR CELLS - A highly doped layer for interconnecting tunnel junctions in multijunction solar cells is presented. The highly doped layer is a delta doped layer in one or both layers of a tunnel diode junction used to connect two or more p-on-n or n-on-p solar cells in a multijunction solar cell. A delta doped layer is made by interrupting the epitaxial growth of one of the layers of the tunnel diode, depositing a delta dopant at a concentration substantially greater than the concentration used in growing the layer of the tunnel diode, and then continuing to epitaxially grow the remaining tunnel diode.09-16-2010

20110255072Compact economical lidar system - A lidar pulse is time resolved in ways that avoid costly, fragile, bulky, high-voltage vacuum devices—and also costly, awkward optical remappers or pushbroom layouts—to provide preferably 3D volumetric imaging from a single pulse, or full-3D volumetric movies. Delay lines or programmed circuits generate time-resolution sweep signals, ideally digital. Preferably, discrete 2D photodiode and transimpedance-amplifier arrays replace a continuous 1D streak-tube cathode. For each pixel a memory-element array forms range bins. An intermediate optical buffer with low, well-controlled capacitance avoids corruption of input signal by these memories.10-20-2011

20090249186MULTI-PASS VALIDATION OF EXTENSIBLE MARKUP LANGUAGE (XML) DOCUMENTS - A validation sequence for an XML document can be identified. The validation sequence can include a set of validation elements. At least one validation pass can be performed for the XML document. Each validation pass can correspond to one of the validation elements. Each validation pass can be configured to validate the XML document for at least one condition defined by the validation element. A validation element result can be produced for each performed validation pass. A validation element result that indicates the XML document is invalid can cause an immediate ending of activities related to the validation sequence, which determines the XML document in general to be invalid. A validation element result that indicates the XML document is valid causes a validation pass to be performed for another one of the validation elements unless each validation element in the validation sequence has been processed. A successful validation of the XML document requires a performance of a successful execution pass for each of the plurality the validation elements.10-01-2009
