摘要:
A supercapacitor comprising a poly(3,4-ethylendioxythiophene) (PEDOT) and poly(3,4-propylenedioxythiophene) (PProDOT) as electrode couples for the capacitor and a pair of gel electrolyte layers disposed between the electrodes. The gel electrolytes are separated by a battery paper and are selected from a group consisting of a lithium salt and an organic electrolyte.

A phototherapy bandage capable of providing radiation to a localized area of a patient for accelerating would healing and pain relief, photodynamic therapy, and for aesthetic applications. The phototherapy bandage may include a flexible light source that is continuous across the bandage for providing a selected light, such as a visible light, a near-infrared light, or other light, having substantially similar intensity across the bandage. The bandage may also be flexible and capable of being attached to a patient without interfering with the patient's daily routine. The phototherapy bandage may easily conform to the curves of a patient and may come in a variety of exterior shapes and sizes.
摘要:
Electrochemical machining is used to generate the helical lobe profiles of the stator of a progressive cavity pump or motor. A thin, elastomeric liner, of uniform thickness is bonded either to the interior of the stator, or to the exterior of the rotor. Where the elastomeric liner is to be bonded to the interior of the stator, bonding is improved by electrically etching the interior of the stator during the electrochemical machining process to produce a roughened surface.

A brake controller for a locomotive includes a train brake pipe, a locomotive brake pipe, a brake cylinder, a control valve being responsive to pressure in the train brake pipe to produce brake apply and brake release signals at an output, and a relay valve having first and second control inputs and having a source input and an exhaust input selectively connected to an output in response to the control inputs. The first control input is selectively connected to one of the output of the control valve and the locomotive brake pipe; and the second control input is selectively connected to the locomotive brake pipe when the control valve output is a release signal. A first electro-pneumatic valve is connected to the control valve which, when activated, causes the control valve to be a release signal. An electronic controller is connected to a first pressure transducer for the locomotive brake pipe, a lead/trail mode switch and the first electro-pneumatic valve and activates the electro-pneumatic valve for brake release pressures in the locomotive brake pipe when the mode switch is in the trail mode.
摘要:
A display system may include a frame, column connection members connected to the frame, and four-sided column members positioned adjacent one another and rotatably connected to the column connection members. Each column member may include a connector and elongate display members positioned adjacent one another and pivotally connected to the connector. The display system may also include a drive assembly carried by the frame that engages the column connection members to rotate each column member so that selective display members pivot in a: predetermined direction during rotation to change the shape of the column members allowing rotation thereof when positioned adjacent one another.
摘要:
A circuit for adapting a level sensitive memory device to exhibit edge-triggered behavior. The adapter circuit can be used with testing modules that expect edge-triggered behavior. The adapting circuit may include address decoding circuitry and output storage and delay circuitry.
摘要:
Sulfur dioxide (SO.sub.2) is absorbed from waste gases by absorbing SO.sub.2 in an aqueous absorbent comprising soluble sulfite in an absorber; stripping the SO.sub.2 from the absorbent; absorbing the stripped SO.sub.2 in a separate absorbent for the SO.sub.2 ; and reacting the thus absorbed SO.sub.2 in a liquid Claus reactor forming sulfur. In a preferred embodiment, the gas from the stripping step is subjected to a condensation step in a heat exchanger boiler where steam ingoing to the stripper is generated.
摘要:
The present locomotive brake control system includes a vacuum relay valve responsive to air brake apply and release signals on the air brake pipe to provide vacuum brake apply and release signals on a vacuum brake pipe. A locomotive brake controller is responsive to the brake apply and release signals on the air brake pipe to control the brake cylinder to apply and release the locomotive brakes in an air mode, and is responsive to the brake apply and release signals on the vacuum brake pipe sensed by a transducer to control the brake cylinder to apply and release the locomotive brakes in a vacuum mode.
摘要:
An EMI shielding material is provided for making EMI shielding gaskets, coating and other articles. The EMI shielding material includes a non-conductive polymer, an inherently conductive polymer and a conductive metal powder. These components are intimately combined to prepare EMI shielding materials having superior electrical and mechanical performance when used in applications such as housings for electronic components.
