A system may include an optical element including a surface defining a recess, conductive material disposed within the recess, and a solder mask disposed over a portion of the conductive material. The solder mask may define an aperture through which light from the optical element may pass. Some aspects provide creation of an optical element including a surface defining a recess, deposition of conductive material on the surface such that a portion of the deposited conductive material is disposed within the recess, and substantial planarization of the surface to expose the portion of the conductive material disposed within the recess.

The present exemplary embodiment relates to an improved flexible display system. One form of the display may use various types of switchable materials contained in micro cells formed from a fabric or mesh material. These cells may serve as a spacer between two opposing electrode sheets and may be individually sealed to the electrode sheets on each face. Moreover, the fabric may, in some forms, be implemented as an electrical grid for addressing the micro cells.

The printing member is supported by the wand body for printing on a media surface, the printing member having a maximum print area for a predetermined position of the wand body relative to a target object substantially less than the entire area of an image to be printed. A reference ruler is provided for aligning and indexing the position of the wand body relative to the target object. A wand tracking system can be provided including the at least one wheel rigidly coupled to the axle for guiding the wand in a straight line direction.

Various fluidic techniques can employ ducting structures, such as microstructures, that extend between other components, such as plate-like structures. A ducting structure can, for example, include an inlet opening toward or near one plate-like structure, an outlet opening toward or near another plate-like structure, and a duct in which fluid flows after being received through the inlet opening and before being provided through the outlet opening. In some implementations, a ducting structure is photo-defined, such as by exposing a photoimageable structure and then removing either exposed or unexposed regions. In some implementations, a ducting structure is a freestanding polymer microstructure. In some implementations, ducting structures are microstructures that extend approximately the same length between first and second plate-like structures, and have a ratio of length to maximum cavity diameter of approximately two or more. A printhead implementation includes an array of such microstructures supported between drive side and drop side assemblies.

A method of operation of an acoustic droplet emitter with an array of droplet emitting utilizing high liquid flow rates. The higher flow rates prevent excess heat absorption during the droplet emission process and allow for excess heat generated by control electronics to be transferred to the flowing liquid after droplet emission but before it leaves the droplet emitter. This prevents excess heat build-up within the droplet emitter and allows for higher more accurate droplet emission.
