摘要:
An electrophoretic-type display device including an array of microcells, where each microcell is formed by a microwell containing a quantity of ink and a polymer-based membrane connected to upper edges of the microwell. The membrane is formed by curing an aqueous or hydroalcoholic sealing solution that is overcoated on the ink-filled microwells. The ink includes an isoparaffinic-based or oil-based suspension fluid, and the peripheral side walls of the microwell have a surface energy in the range of 20 to 30 mN/m. The microwell material serves two purposes: to prevent displacement (floating) of the relatively light ink solution above the relatively heavy sealing solution, and to facilitate reliable attachment between the polymer membrane and microwell walls during subsequent curing.

An apparatus for merging and mixing two droplets using electrostatic forces includes a substrate on which are disposed a first originating electrode, a center electrode, and a second originating electrode. The electrodes are disposed such that a first gap is formed between the first originating electrode and the center electrode and a second gap is formed between the second originating electrode and the center electrode. A dielectric material surrounds the electrodes on the substrate. A first droplet is deposited asymmetrically across the first gap, and a second droplet is deposited asymmetrically across the second gap. Voltage potentials are placed across the first gap and second gap, respectively, whereby each droplet is moved toward the other such that they collide together, causing the droplets to merge and mix, and causing oscillations within the collided droplet.

Various structures, such as microstructures and wall-like structures, can include parts or surfaces that are oblique. In some implementations, a cantilevered element includes a spring-like portion with a uniformly oblique surface or with another artifact of an oblique radiation technique. In some implementations, when a deflecting force is applied, a spring-like portion can provide deflection and spring force within required ranges. Various oblique radiation techniques can be used, such as radiation of a layer through a prism, and structures having spring-like portions with oblique radiation artifacts can be used in various applications, such as with downward or upward deflecting forces.

Various traveling wave grids and related systems are disclosed that are particularly beneficial for the separation, transport, and focusing of biomolecules or other charged species. An implementation of a vertically integrated traveling wave module is described which allows for scalability to arbitrary gel dimensions through tiling. In addition, several unique traveling wave algorithms are also described which when used in conjunction with the traveling wave grids, impart selective motion to biomolecules or other charged species.

A system and corresponding methods are disclosed for applying a dampening fluid to a reimageable surface of an imaging member in a variable data lithography system, without a form roller. In one embodiment, the system includes subsystems for converting a dampening fluid from a liquid phase to a dispersed fluid phase, and for directing flow of a dispersed fluid comprising the dampening fluid in dispersed fluid phase to the reimageable surface. The dampening fluid reverts to the liquid phase directly on the reimageable surface. In another embodiment a continuous ribbon of dampening fluid may be applied directly to the reimageable surface. This embodiment includes a body structure having a port for delivering dampening fluid in a continuous fluid ribbon directly to the reimageable surface, and a mechanism, associated with the body structure, for stripping an entrained air layer over the reimageable surface when the reimageable surface is in motion.

摘要:
An electrical interconnect device attaches electrical devices with a cantilever spring with out the use of solder or adhesive. The cantilever spring latches to a contact structure such that there are a plurality of contact points between the spring and the contact structure. The cantilever spring has two tines at a tip end that define an opening in the spring. The contact structure is received by the opening between the two tines so that the spring and the contact structure mate. The spring may engage the contact structure by latching to the contact structure or by a post that urges the tip end of the spring against the contact structure.

A socket for solderless connection between a stud-bumped IC chip and a host PCB. The socket includes a three-dimensional (e.g., cylindrical or cubical) hollow metal frame that is either free-standing or supported by an underlying patterned template structure. The metal frame includes side walls that extend away from the host PCB, and a contact structure located at the upper (i.e., free) end of the side walls. The contact structure defines an opening through which a stud bump can be inserted into a central chamber of the metal frame. The side walls and/or the contact structure are formed such that when the tip end of the stud bump is inserted into the central chamber, at least one of the base structure and the sidewall of the stud bump abuts the contact structure at two or more contact points.
摘要:
A novel reflective display system is described. The display system is viewable through the display backplane instead of the counterelectrode. Making the display viewable through the backplane allows use of a conducting elastomer as a counterelectrode which facilitates fabrication of a flexible display. The rear-viewable display also facilitates attachment of color filters directly to the backplane simplifying filter pixel alignment issues.
