摘要:
A propulsion device including a chamber that stores a superfluid, a substrate coupled to a portion of the chamber, a plurality of orifices extending through the substrate, each of the plurality of orifices having a first end and a second end opposite the first end, the first end disposed in an interior of the chamber and the second end disposed outside the chamber; and a pressure source that generates a pressure differential between the first end of each of the plurality of orifices and the second end of each of the plurality of orifices.

Embodiments of an electronic instrument simulating a percussion instrument using capacitive touch sensitive sensors are described herein. Embodiments described comprise an art layer, a sensor layer, a shielding layer, an electronics package and a speaker. The art layer has depictions of one or more percussion instruments. The sensor layer is deposed under the art layer. The sensor layer has one or more instrument sensors, each comprising one or more capacitive touch sensors. Instrument sensors are positioned underneath one of the depicted percussion instruments in the art layer so that a finger tapping the depicted instrument will trigger the sensor. The capacitive touch sensors are electrically connected to the electronics package configured to detect changes in capacitance when a particular capacitive touch sensor is touched, causing the electronics package to play on the speaker a sound sample of an percussion instrument associated with that capacitive touch sensor.

Thin film capacitive touch sensors and applications thereof are described herein. Embodiments include construction of one-sided and two-sided thin film capacitive touch sensors with partial fill patterns, one-sided thin film capacitive touch sensors including conductive ground plane layers, one-sided thin film capacitive touch sensors including air gap layers, one-sided thin film capacitive touch sensors including a combination of both separation layers to create air gap layers and conductive ground plane layers.
摘要:
This invention comprises USY zeolite prepared by treating a USY zeolite under hydrothermal conditions after forming the USY zeolite from heat treating ammonium exchanged zeolite Y, e g, by calcination. When this invention is used in a FCC catalyst, a significant improvement of activity and selectivity in the fluid catalytic cracking (FCC) performance is observed, compared to FCC catalysts containing conventional USY zeolite. The process used to make the invention is efficient and comprises treating the USY zeolite in an exchange bath under the aforementioned hydrothermal conditions. The surface of the resulting USY zeolite has a molar ratio of alumina to silica that is higher than that seen in the bulk USY zeolite and has a unique structure as viewed by SEM and TEM.

The present invention provides an embolic assembly delivery apparatus having superior flexibility characteristics at its distal end, that is, at the point of attachment of the embolic assembly to the delivery apparatus. It also provides a method of using the apparatus to deliver an embolic assembly to a target site in a patient's body.
摘要:
A method for providing therapy to tissue at a treatment site is performed by ablating tissue at the treatment site with an ablation device. Next, a cleaning device is attached to an instrument. The cleaning device attached to the instrument is used to remove ablated tissue at the treatment site. The cleaning device may also be used to remove debris from the treatment site prior to ablation or other therapeutic or diagnostic procedure.
摘要:
An ablation device and methods for use thereof including a support structure adapted to support an ablation structure within an alimentary tract of a patient are provided. The support structure includes a longitudinal support with a longitudinal axis and a rotational support. The rotational support is adapted to permit at least part of the ablation structure to rotate with respect to the longitudinal support's longitudinal axis.
