20110224479 | EDDY CURRENT INDUCED HYPERTHERMIA USING CONDUCTIVE PARTICLES - Technologies are generally described for hyperthermia based treatment of diseased tissues using conductive particles. Conductive particles of known composition and size distribution may be implanted in diseased tissue and exposed to an alternating magnetic field, which may be tuned to the size of the metal particles to induce eddy currents producing heat in the implanted particles. As the temperature of the metal particles increases, their resistance also increases due to their positive temperature coefficient of resistivity. An antenna placed externally to the body near metal particles may be part of a tuned RF circuit and scanned for resonance. The change either in resonance frequency or circuit impedance may provide tuned feedback, which may be used to control the hyperthermia treatment. | 09-15-2011 |
20110234240 | MONITORING DEHYDRATION USING RF DIELECTRIC RESONATOR OSCILLATOR - Technologies are generally described for monitoring dehydration levels of a subject using Radio Frequency (RF) dielectric resonant oscillators (DROs) that may be affixed to the skin of the subject. According to some example aspects, a sensor comprising a microstrip ring resonator may be affixed to the skin and used to determine the change in hydration of a person quantitatively and/or qualitatively. An RF emitter can be configured to emit a scanning signal to the sensor, where the scanning signal can be swept over a specified frequency range. The sensor is configured to resonate in response to the scanning signal, where characteristics of the sensor's resonance (e.g., the specific frequency and “Q” factor of the resonance) is impacted by dielectric losses of the sensor to the skin due to hydration level of the subject. | 09-29-2011 |

20120234730 | RADIATION ASSISTED ELECTROSTATIC SEPARATION OF SEMICONDUCTOR MATERIALS - A method of separating material includes providing a mixture of a first material, such as a semiconductor, and a second material, such as an insulator or a different semiconductor. The mixture can be irradiated using a light source at a wavelength that causes the first material's conductivity to increase while leaving the second material's conductivity (substantially) unchanged. Placing the mixture in contact with a ground electrode discharges the first material but not the second material due the difference in their conductivities. Applying an electric field to the discharged mixture separates the discharged first material from the second material. | 09-20-2012 |

20120252934 | Microcapsule Corrosion Control In Reinforced Concrete - Corrosion control in reinforced concrete is generally disclosed. Some example embodiments may include concrete including aggregate, cement, and/or microcapsules distributed within the cement, where the individual microcapsules may include a high pH salt substantially contained within an acid-soluble shell. If the pH of the concrete decreases, the acid soluble shell may swell and/or dissolve, such as below a pH of about 11, which may release the high pH salt. The high pH salt may locally increase the pH of the concrete. By increasing the pH above about pH 11, corrosion of steel rebar may be prevented and/or reduced. | 10-04-2012 |

20130026108 | PIEZOELECTRIC DISCHARGE WATER PURIFICATION - The fluid purification disclosed herein provides the advantages of high-voltage purification without electrocution risks. In illustrative purifiers, a contaminated fluid, such as contaminated water, is aerated and passed through a cavity that contains highly porous piezoelectric material and an ultrasonic transducer. The transducer emits ultrasonic energy that causes the piezoelectric material to discharge a high-voltage field, which produces strong oxidizing agents that kill organisms and oxidize organic pollutants. Since the ultrasonic actuator operates at relatively low voltages (e.g., 20-110 V) and can be electrically isolated from the fluid, illustrative purification is safe, environmentally friendly, and scalable from small to large size applications. | 01-31-2013 |

20140200437 | DETECTION OF INTERNAL GAS LEAKAGE - A method placing a gas into a first cavity of a patient, where the gas includes hyperpolarized 3-Helium (3-He). At least a portion of the patient is imaged using MRI to detect the gas within the patient. Based at least in part on the imaging, a determination is made regarding whether at least a portion of the gas is present in a second cavity of the patient. Presence of the gas in the second cavity is indicative of a leakage of the first cavity. | 07-17-2014 |
20140285796 | DEFECT DETECTION IN SATURABLE ABSORBERS - Technologies are generally described for identifying defects in saturable absorbers, such as graphene, by the saturable property of decreasing light absorbance with increasing light intensity. For example, a graphene coated substrate may be imaged twice under two distinct incident intensities. At a gap in the graphene, the substrate may reflect light proportional to the incident intensities. The graphene may show a non-linear increase in reflected light as the intensity of illumination increases. A difference between the two incident intensities may reveal the gap in the graphene. Any suitable imaging technique may be employed such as confocal microscopy or linear scanning. The imaging may be scaled up for high volume automated inspection. | 09-25-2014 |
20150079683 | METHODS AND SYSTEMS FOR LABELING AND DETECTING DEFECTS IN A GRAPHENE LAYER - Fluorophores or other indicators can be used to label and identify one or more defects in a graphene layer by localizing at the one or more defects and not at other areas of the graphene layer. A substrate having a surface at least partially covered by the graphene layer may be contacted with the fluorophore such that the fluorophore selectively binds with one or more areas of the surface of the underlying substrate exposed by the one or more defects. The one or more defects can be identified by exposing the substrate to radiation. A detected fluorescence response of the fluorophore to the radiation identifies the one or more defects. | 03-19-2015 |
