The present invention provides methods and system for managing neurological disorders such as epilepsy. In one embodiment, the method comprises measuring one or more signals from a patient and processing the one or more signals to characterize a patient's propensity for a future seizure. The characterized propensity for the seizure is thereafter used to determine an appropriate action for managing or treating the predicted seizure; and a recommendation is communicated to the patient that is indicative of the appropriate action.

The present invention thus provides a simple and automatic method for determining an optimal AV interval and/or range of AV intervals for, in an exemplary embodiment, LV-only pacing. Such a method provides significant advantages for patients while reducing burdens related to post-implant follow-up by clinicians in that it greatly reduces the need for doing echocardiographic-based AV interval optimization procedures as well as providing a way to dynamically optimize AV intervals as the patient moves about their activities of daily living (ADL).

A method for synergistically treating a joint of an animal, including introducing a cushioning agent into a joint; and introducing an enzyme or hormone adapted to stimulate cartilage production into the joint. The joint may be subjected to a compression regimen following injection of the cushioning agent and enzyme/hormone. Alternatively, the invention may include a composition for synergistically treating a joint of an animal, comprising a viscous cushioning material adapted to be introduced within a joint space to provide cushioning for the joint, and hormones dispersed through the cushioning material, the hormones operable to increase cartilage production.

A method for fabricating a light-emitting semiconductor device including a III-Nitride quantum well layer includes selecting a facet orientation of the quantum well layer to control a field strength of a piezoelectric field and/or a field strength of a spontaneous electric field in the quantum well layer, and growing the quantum well layer with the selected facet orientation. The facet orientation may be selected to reduce the magnitude of a piezoelectric field and/or the magnitude of a spontaneous electric field, for example. The facet orientation may also be selected to control or reduce the magnitude of the combined piezoelectric and spontaneous electric field strength.

A method involves pre-heating a workpiece to an intermediate temperature, heating a surface of the workpiece to a desired temperature greater than the intermediate temperature, and enhancing cooling of the workpiece. Enhancing cooling may involve absorbing radiation thermally emitted by the workpiece. An apparatus includes a first heating source for heating a first surface of a semiconductor wafer, a second heating source for heating a second surface of the semiconductor wafer, and a first cooled window disposed between the first heating source and the semiconductor wafer.

A system and related method for improving tire uniformity includes providing a number (n) of test tires manufactured in a known order and identifying at least one candidate cyclic process effect with a corresponding frequency of introduction (f). A given uniformity parameter, such as radial or lateral run-out, balance, mass variation, radial lateral or tangential force variation, is measured for each tire in the test set, and measured data points are combined into a concatenated composite waveform. At least one process harmonic associated with each identified cyclic process effect is separated from the tire harmonics, for example, by Fourier transformation with identification of the process harmonics as positive integer multiples of the mth harmonic of the measured uniformity parameter where m=n/f. Once the process harmonics are extracted, filtered uniformity measurements can be provided or new tires can be built with the process effect minimized.

A system and related method for improving tire uniformity includes identifying at least one candidate process effect and a corresponding process harmonic number for each process effect. A given uniformity parameter, such as radial or lateral run-out, balance, mass variation, radial lateral or tangential force variation, is measured for each tire in a test set, such that the measurements contain tire harmonics as well as a process harmonics corresponding to each candidate process effect. Rectangular coordinate coefficients are electronically constructed for each said process harmonic, after which point the rectangular coordinates corresponding to each process harmonic are solved for (e.g., by using regression-based analysis). The magnitude of each said process harmonic is estimated, and a final magnitude estimate for each process harmonic can be determined by summarizing (e.g., by taking the average or median value) the respectively estimated magnitudes for each process harmonic across all test tires.

A refiner disc and segment for a rotary disc fiber refiner which has a plurality of radial fields each having an angular extent no greater than 30° and preferably no greater than 22° for reducing the amplitude and duration of load swings that take place during pumping and holdback cycles. Each field has a refining zone with a refiner groove and a refiner bar and a second zone disposed radially outwardly of the refining zone that changes the direction of flow of stock to reduce stock flow momentum and magnitude of the load swings. Each field can have a third zone radially outward of the second zone that further changes the direction of flow of stock and an infeed zone radially inwardly of the refining zone. If desired, a zone that includes a breaker bar can be disposed radially inwardly of the infeed zone. Where the disc is segmented, the segment has at least three fields. In one preferred embodiment, the segment has at least four fields which reduces the duration and magnitude of load swings by at least 40% thereby reducing refiner vibration and wear while advantageously increasing consistency of pulp quality and throughput. The disc and segment are capable of bi-directional operation without loss of efficiency, quality, and throughput.

A multiscale telescopic imaging system is disclosed. The system includes an objective lens, having a wide field of view, which forms an intermediate image of a scene at a substantially spherical image surface. A plurality of microcameras in a microcamera array relay image portions of the intermediate image onto their respective focal-plane arrays, while simultaneously correcting at least one localized aberration in their respective image portions. The microcameras in the microcamera array are arranged such that the fields of view of adjacent microcameras overlap enabling field points of the intermediate image to be relayed by multiple microcameras. The microcamera array and objective lens are arranged such that light from the scene can reach the objective lens while mitigating deleterious effects such as obscuration and vignetting.

Thin film transistors and arrays having controlled threshold voltage and improved I_ON/I_OFF ratio are provided in this invention. In one embodiment, a thin film transistor having a first gate insulator of high breakdown field with positive fixed charges and a second gate insulator with negative fixed charges is provided; said negative fixed charges substantially compensate said positive fixed charges in order to reduce threshold voltage and OFF state threshold voltage of said transistor. In another embodiment, a thin film transistor having a first passivation layer with negative fixed charges is provided, the negative charges reduce substantially unwanted negative charges in the adjacent active channel and hence reduce the OFF state current and increase I_ON/I_OFF ratio, which in turn reduce the threshold voltage of the transistor.
