摘要:
A dry preunit (10), includes a plurality of cells (110, 112, 114) in a true bipolar configuration, which are stacked and bonded together, to impart to the device an integral and unitary construction. Each cell (114) includes two electrically conductive electrodes (111A, 111B) that are spaced apart by a predetermined distance. The cell (114) also includes two identical dielectric gaskets (121, 123) that are interposed, in registration with each other, between the electrodes (111A, 11B), for separating and electrically insulating these electrodes. When the electrodes (111A, 111B), and the gaskets (121, 123) are bonded together, at least one fill gap (130) is formed for each cell. Each cell (114) also includes a porous and conductive coating layer (119, 120) that is formed on one surface of each electrode. The coating layer (119) includes a set of closely spaced-apart peripheral microprotrusions (125), and a set of distally spaced-apart central microprotrusions (127). These microprotrusions (125, 127) impart structural support to the cells, and provide additional insulation between the electrodes. An energy storage device (10A) such as a capacitor, is created with the addition of an electrolyte to the gap (130) of the dry preunit (10) and subsequent sealing of the fill ports.

摘要:
The present invention relates to an improved method to produce an electrical storage device having useful characteristics such as higher charge density, small volume, long-term reliable charge/discharge cycles, low leakage current, and the like. The dry preunit has useful properties in that it can be stored for long periods prior to contact with a non-aqueous or aqueous electrolyte. When the electrode surfaces are contacted with a non-aqueous or aqueous electrolyte, the novel capacitors produced are useful as a portable power supply in applications such as in defibrillator, electrical vehicles, radiotelephones etc.

摘要:
Electrodes of an electrical charge storage device are separated by forming on the surfaces of the electrodes arrays of substantially uniform electrically insulating microprotrusions made preferably of an organic epoxide polymer. The electrodes are thin, flat electrically conducting metal sheets coated on one or both flat surfaces with electrically conducting porous carbon or a porous metal oxide. The microprotrusions are applied to the coated electrodes through a stencil by screen printing and essentially retain their shape and dimensions after curing.

The present invention provides a system and method for providing a self-cleaning water circulation system which may be utilized for a fish pond, fountain, or the like. Means for automatically cleaning the pump intake to avoid pump failure due to leaves and debris is provided. The circulation system also comprises a self-cleaning filter for cleaning the circulated water whereby maintenance requirements are substantially reduced.
摘要:
A method includes populating components in a cavity of a substrate, disposing a polymer over the components and within the cavity. The polymer is cured and a thin film is formed on the polymer. In addition, a method includes forming an EMI shield within a medical device by depositing a thin film of metal on a surface within the medical device. The thin film of metal, of gold, aluminum, or copper, is formed by vapor deposition or sputtering.
摘要:
A multi-capacitor module carries vertically-oriented surface mount tantalum capacitors. The module provides at least one conductor for coupling to the substrate capacitor terminals that are distal thereto. The module occupies less space, when mounted to a circuit board substrate, than individually mounting the bases of the surface mount capacitors to the substrate. This allows more efficient use of volume within an implantable cardiac rhythm management device, reducing its size, or alternatively, increasing its implanted longevity.
