Abstract: A method of removing contaminants from slurry samples is set forth. The method includes the utilization of repeated pressurizing and depressurizing steps to disrupt solidified particles in solid-containing slurries thereby increasing decontamination efficiency. An expansion fluid is injected into the slurry sample sufficient to create microbubbles when the slurry sample is depressurized. The micro bubbles mechanically disrupt the solidified particles increasing contaminant exposure. The microbubbles also provide for increased interfacial regions where contaminants can accumulate at gas-liquid thin films that are in close proximity to and can be effectively removed using a suitable expansion fluid and optional decontamination agents.
Abstract: Nanoelectromechanical logic devices can include a plurality of flexible bridges having control and logic electrodes. Voltages applied to control electrodes can be used to control flexing of the bridges. The logic electrodes can provide logical functions of the applied voltages.

Abstract: Systems, methods and devices which utilize Spread Spectrum Time Domain Reflectometry (SSTDR) techniques to measure degradation of electronic components are provided. Such measurements may be implemented while the components “live” or otherwise functioning within an overall system. In one embodiment, monitoring a power converter in a high power system is accomplished. In this embodiment, degradation of components within the power converter (e.g. metal-oxide-semiconductor field-effect transistors (MOSFETs), capacitors, insulated-gate bipolar transistors (IGBTs), and the like) may be monitored by processing data from reflections of an SSTDR signal to determine changes in impedance, capacitance, or any other changes that may be characteristic of components degrading. For example, an aging MOSFET may experience an increase of drain to source resistance which adds additional resistance to a current path within a power converter.

Abstract: Embodiments are directed to a ground reaction sensor cluster (GRSC) and to methods for precisely determining zero velocity points and bearing changes using a GRSC and for navigating using a GRSC and an inertial motion unit (IMU) in a global positioning satellite (GPS)-denied environment. The GRSC device itself includes an array of capacitive pressure and shear sensors. The array includes multiple flexible capacitive sensor cells that detect changes in capacitance in response to a footstep. Each cell of the array includes multiple overlapping, fingered capacitors that detect pressure and shear force by determining the change in capacitance in each fingered capacitor. The GRSC device also includes a multiplexing receiver that receives the capacitance inputs from each of the capacitive sensor cells. The multiplexing receiver and other electronic elements further process the received capacitance inputs to determine, based on the pressure and shear forces, the direction and bearing of the footstep.

Abstract: Apparatus, assemblies, and methods for capturing objects within a body are disclosed. A surgical snare device includes a steerable deflection portion with a steerable distal tip. An interface is linked to the steerable deflection portion to selectively manipulate the distal tip. A snare loop disposed at the distal tip can have a length that remains substantially constant as the distal tip is deflected and the snare loop moves in concert with the distal tip. The distal tip may deflect up to at least one-hundred eighty degrees, while the snare loop moves a corresponding amount. A method includes extending a snare through a body lumen and to a location near an object. The snare may have a loop that changes positions while maintaining the same length. The loop may be placed around an object and then used to retrieve the object from the body lumen.

Abstract: Methods and systems are described for determining, in a patient that suffers from a mood disorder (e.g., depression), a propensity of the patient to manifest reduced symptoms or levels of indicators of the mood disorder in response to a psychiatric treatment. This can involve determining levels of a marker (e.g., a metabolite) indicative of a brain bioenergetic state of the patient that is predictive of whether the patient will response favorably to an antidepression treatment. Such bioenergetic state markers, tending to normalize in response to antidepression therapy, can include, e.g., a pH, a magnesium level, and a phosphorus level. Brain levels of such markers can be determined by, e.g., 31P MRS.

Abstract: A ceramic material having a high toughness can include carbon and a transition metal. The transition metal can have an elemental body centered cubic structure at room temperature. A substantial amount of the ceramic can be of a rhombohedral ? phase of the transition metal and carbon. These materials can have a high thermal shock resistance, high fracture toughness, and good high temperature performance. A particulate mixture of a carbon source and a transition metal source can be assembled (12) and reacted (14) under high pressure and high temperature. The transition metal source can include a transition metal of a metal which has an elemental BCC structure at room temperature. The particulate mixture carbon to transition metal ratio is chosen so as to achieve a zeta phase carbide and processing is affected in order to retain the zeta phase at a substantial weight percent of the material (i.e. greater than about 5 wt %).

Abstract: An organic light emitting diode (OLED) uses a ?-conjugated polymer emissive layer (MEH-PPV) sandwiched between two semitransparent electrodes. The preferred embodiment utilizes an optically thin gold film anode, whereas the cathode was in the form of an optically thick aluminum (Al) film with patterned periodic subwavelength 2D hole array that showed anomalous transmission in the spectral range of the polymer photoluminescence band. At similar current densities we obtained a seven-fold electroluminescence efficiency enhancement with the patterned Al device compared with a control device based on unperforated Al electrode.
