Abstract:
Methods of forming a graphene-based device are provided. According to an embodiment, a graphene-based device can be formed by subjecting a substrate having a dielectric formed thereon to a chemical vapor deposition (CVD) process using a cracked hydrocarbon or a physical vapor deposition (PVD) process using a graphite source; and performing an annealing process. The annealing process can be performed to temperatures of 1000 K or more. The cracked hydrocarbon of the CVD process can be cracked ethylene. In accordance with one embodiment, the application of the cracked ethylene to a MgO(111) surface followed by an annealing under ultra high vacuum conditions can result in a structure on the MgO(111) surface of an ordered graphene film with an oxidized carbon-containing interfacial layer therebetween. In another embodiment, the PVD process can be used to form single or multiple monolayers of graphene.
Abstract:
Embodiments of the invention provide methods and devices for improved drainage systems and tubing. In one embodiment, a context-sensitive flow interrupter is provided that inhibits or facilitates flow of fluid when engaged with a mating holder. In another embodiment, outflow is optimized through control of the pressure in gas pockets in a tube, drainage tube or assembly. In one such embodiment, gas pockets are vented to inhibit excessive back-pressure or suction on an organ, vessel or cavity being drained. In another such embodiment, loops in the tubes are avoided by using a mechanical template in the form of a groove or peg assembly to thread the slack in the drainage tube to generate a monotonic gradient. In another embodiment, such as for active drainage systems, a bypass channel is provided that allows an applied vacuum to go around an obstruction created by the collection of fluid in an undrained dependent loop.
Abstract:
An enhancement mode (E-mode) HEMT is provided that can be used for analog and digital applications, In a specific embodiment, the HEMT can be an AlN/GaN HEMT. The subject E-mode device can be applied to high power, high voltage, high temperature applications, including but not limited to telecommunications, switches, hybrid electric vehicles, power flow control and remote sensing. According to an embodiment of the present invention, E-mode devices can be fabricated by performing an oxygen plasma treatment with respect to the gate area of the HEMT. The oxygen plasma treatment can be, for example, an O2 plasma treatment. In addition, the threshold voltage of the E-mode HEMT can be controlled by adjusting the oxygen plasma exposure time. By using a masking layer protecting regions for depletion mode (D-mode) devices, D-mode and E-mode devices can be fabricated on a same chip.

A MEMS-based Fourier Transform (FT) spectrometer is provided. According to an embodiment, the MEMS-based FT spectrometer is an FT infrared (FTIR) spectrometer. The FT spectrometer can include a beam splitter positioned to receive an incoming beam from a light source and split the incoming beam into a first sub-beam and a second sub-beam, a fixed mirror positioned to receive the first sub-beam from the beam splitter, a scanning MEMS mirror positioned to receive the second sub-beam from the beam splitter, and a photodetector, wherein a reflected first sub-beam from the fixed mirror and a reflected second sub-beam from the scanning MEMS mirror recombine at the beam splitter and become directed to the photodetector. According to one embodiment, the photodetector is a MEMS-based IR detector. In addition, the MEMS-based IR detector can be an un-cooled IR detector having a capacitive sensing structure.
Abstract:
A data collection procedure is described, which can be performed automatically for each subject of a study as the participant produces the data being collected. In one case, the procedure transforms the data matrix X (of the participants' data) to AXB, where matrix A is a row operator that transforms data records (cases) in X and matrix B is a column operator that transforms data attributes (variables) in X, and the keys to generate these random operators are held separately by different parties. In another case, each participant's data is decomposed into a sum of k vectors before being collected and variously transformed by a plurality of masking service providers.
Abstract:
Detection of neurological diseases such as Parkinson's disease can be accomplished through analyzing a subject's speech for acoustic measures based on human factor cepstral coefficients (HFCC). Upon receiving a speech sample from a subject, a signal analysis can be performed that includes identifying articulation range and articulation rate using HFCC and delta coefficients. A likelihood of Parkinson's disease, for example, can be determined based upon the identified articulation range and articulation rate of the speech.
Abstract:
Subscription based multiple-input-single-output and multiple-input-multiple-output wireless energy transfer enables selective charging and powering of mobile devices using a plurality of spatially distributed transmitters that are synchronized under the control of a transmitter controller. Amplitude, phase, and frequency of each transmitter is controlled to promote or deny the transfer of energy to particular mobile devices or positions through optimization techniques based on the incident power level at each mobile device subscribing to the system. Measurements related to the incident power level may be directly provided by the mobile device or the incident power is remotely determined through analysis of backscatter gains.
Abstract:
Methods and systems for patient participatory care and monitoring are provided for applications including respiratory care, ECG monitoring, capnography, infusion pump alarm prevention/management, pressure sore prevention, incentive spirometry, consciousness monitoring during sedation, pain management and other care and monitoring modalities. A patient in-the-loop system includes an input interface for receiving data acquired from a monitoring, controlling or sensing device, a storage device for storing the data at a first location, and a processor for analyzing artifacts in the data and determining whether the patient provided a deliberate action with respect to the device as a response to a prompt or query. The processor can further initiate a variety of prompts and/or output queries stored in the storage device at a second location to the patient. The data derived from these patient-in- the-loop techniques are formatted to be received and interpreted by electronic medical record and electronic record keeping systems.
Abstract:
Systems and techniques are provided for high frequency clock (or local oscillator) distribution and phase shifting. According to one embodiment, an injection locking frequency multiplier is used to realize both frequency multiplication and phase shifting in a cell of an array system, multi-core processor, or network-on-chip system, enabling a lower than operating frequency local oscillator distribution to the cell. With four control bits (16 values) to an injection locking frequency multiplier (either as a single multiplier circuit or multiplier chain), a 360 degree phase control can be achieved.
