An implantable medical device, such as a bi-directional infuser device for hydraulically controlling an artificial sphincter (e.g., adjustable gastric band) benefits from being remotely powered by transcutaneous energy transfer (TET), obviating the need for batteries. In order for active components in the medical device to operate, a sinusoidal power signal received by a secondary coil is rectified and filtered. An amount of power transferred is modulated. In one version, a voltage comparison is made of a resulting power supply voltage as referenced to a threshold to control pulse width modulation (PWM) of the received sinusoidal power signal, achieving voltage regulation. Versions incorporate detuning or uncoupling of the secondary coil to achieve PWM control without causing excessive heating of the medical device.

A pattern forming method includes preparing a target object including silicon with an initial pattern formed thereon and having a first line width; performing a plasma oxidation process on the silicon surface inside a process chamber of a plasma processing apparatus and thereby forming a silicon oxide film on a surface of the initial pattern; and removing the silicon oxide film.

A rotary wing aircraft apparatus includes a body and a rotor pair connected to the body by an arm. The rotor pair has an upper rotor driven by an upper motor and rotating about an upper rotor axis and a lower rotor driven by a lower motor and rotating about a lower rotor axis. The upper and lower rotor axes are tilted with respect to each other. Tilting the axes away from the arm increases the distance from the rotor blades to the arm, and decreases the risk of the blades of the rotor contacting the arm. In an aircraft with a plurality of arms extending from the body, and a rotor assembly connected to each arm, the arms can be pivoted from a flying position, where the arms extend laterally outward to a folded position where the arms are positioned substantially parallel and adjacent to each other.

The invention relates to an accelerated data query method in a query system, which provides an accelerated data query method based on a cache of document system according to the features of unchanged saved historical data and frequent query of same data. The invention saves the historical query data and takes it as the cache data for query, so as to accelerate the query. Upon receiving the query quest from user, the system will first of all turn to the query analyzer; the principal function of the query analyzer is to analyze and plan the query condition; then, after passing through a document buffer, the system analyzes whether the data document in the result satisfies the present query need; if not, the query will be carried out in the database and the final result will be fed back to a data processor; then, the data processor will filter and sort the data according to the final query demand and finally feed back the result document to a super stratum application system. Therefore, without increasing the investment on hardware, this query method is able to greatly reduce the occupation of database and system resource, so as to improve the query speed.

An apparatus and method for rehabilitating patients and assessing tactile skills in response to visual stimuli generated from a portable neural training device. The device generates a visual output to elicit tactile response (hand movement) from the patient. The device preferably automatically adjusts the difficulty of a session in response to demonstrated patient skill level (i.e. combination of correct responses, speed, and accuracy of responses). The invention evaluates and challenges the patient to control tactile response, overcome visual perception difficulties, or practice simple multi-tasking or reasoning skills. The invention also provides information which is valuable to those administering the rehabilitation program or assessing patient skill and / or progress. By way of example the neural training device is described with an embodiment having discrete fixed keys and an embodiment utilizing a touch sensitive display screen.
