摘要:
An electrolyte system (40) for use in connection with an electrochemical cell (10). The cell (10) includes a positive electrode (20) and a negative electrode (30) with the electrolyte system (40) disposed therebetween. The electrolyte system is a polymer gel electrolyte system including an electrolyte active species which may be either aqueous or non-aqueous and a polymer gel electrolyte support structure. The blended polymer gel electrolyte support structure includes at least a first phase adapted to absorb or otherwise engage the electrolyte active species disposed on and through the pores of a second phase which is substantially inert and does not absorb the electrolyte active species.

An electrochemical cell (10) includes first and second electrodes (12) and (14) with an electrolyte system (26) disposed therebetween. The electrolyte system includes at least a filler material and a gelling polymer. The filler material comprises at least about 50 vol. % of the total amount of polymer in the electrolyte system, and has a porosity on the order of about 20-80%.

An electrochemical cell 10 includes first and second electrodes 12 and 14 with an electrolyte system 26 disposed therebetween. The electrolyte system includes at least a first and second layer 28 and 30, the second layer 30 being used to absorb an electrolyte active species and to adhere the adjacent layer of electrode material to the electrolyte 26. The electrolyte system further includes a process for packaging and curing the electrolyte after it has been incorporated into a discrete battery device.

摘要:
An electrolyte system (40) for use in connection with an electrochemical cell (10). The cell (10) includes a positive electrode (20) and a negative electrode (30) with the electrolyte system (40) disposed therebetween. The electrolyte system is a polymer gel electrolyte system including a liquid electrolyte species which may be either aqueous or non-aqueous and a polymer gel electrolyte support structure. The polymer gel electrolyte support structure includes at least an non woven first polymer and a second polymer which is adapted to absorb the electrolyte active species. The first polymer is a fibrous polymer to reduce swelling of the gel electrolyte in the presence of the electrolyte active species, and further to enhance mechanical integrity of the support structure.

A tactile interface for an electronic device includes a compliant portion, a first input sensor embedded in the compliant portion and a second input sensor. The first and second sensors produce differential output signal in responsive to tactile input forces applied in at least a common dimension or about a common axis. A processor detects and interprets the differential output signals as a tactile input at the touch input device.

An apparatus is provided for detecting an atmospheric component. The apparatus comprises one or more arrays, wherein each array comprises one or more colorimetric reagents. A material encapsulating the colorimetric reagents of each array is capable of being at least partially removed to expose the colorimetric reagents of a selected array to the atmosphere. An imager detects colors of the one or more colorimetric reagents in the selected array. Circuitry then determines changes in colors of the one or more colorimetric reagents within the selected array.

An optical waveguide (106) with directional microprisms (116) and multidirectional light sources (110)(112) are provided for providing overlapping morphing images (104) and information (102) on a display (124) of a touch screen mobile phone or other electronic device (100). Microprisms can be patterned in the shape of a particular design, character, icon or other image. The microprisms can include: first microprisms (118) sensitive to light propagating in only one direction; second microprisms (120) sensitive to light propagating in a different direction, and a third microprisms (122) sensitive to light propagation in multiple directions. When light is directed into the waveguide (106) in a direction to which a portion of the microprisms (116) are sensitive, a fraction of that light will be directed upward and out of the waveguide (106) by those microprisms sensitive to light propagated in that direction. Controlling, switching or selectively activating the light sources (110)(112) results in different images (104) which are displayed and illuminated on the display (124) of the electronic device (100).
摘要:
An exemplary device and method for microfluidic transport is disclosed as providing inter alia a passive check valve (100), a fluid inlet channel (210), a fluid outlet channel (220) and a pumping cavity (240). The fluid inlet channel (210) is generally configured to flow a fluid through the check valve (100). The check valve (100) generally provides substantially passive means for preventing or otherwise decreasing the incidence of purged outlet fluid re-entering either the pumping cavity (240) or the fluid inlet channel (210). Accordingly, the reduction of backflow generally tends to enhance overall pumping performance and efficiency. Disclosed features and specifications may be variously controlled, adapted or otherwise optionally modified to improve micropump operation in any microfluidic application. Exemplary embodiments of the present invention representatively provide for substantially self-priming micropumps that may be readily integrated with, for example, existing portable ceramic technologies for the improvement of device package form factors, weights and other manufacturing and/or device performance metrics.
