Abstract: Xerographic micro-assembler systems and methods are disclosed. The systems and methods involve manipulating charge-encoded micro-objects. The charge encoding identifies each micro-object and specifies its orientation for sorting. The micro-objects are sorted in a sorting unit so that they have defined positions and orientations. The sorting unit has the capability of electrostatically and magnetically manipulating the micro-objects based on their select charge encoding. The sorted micro-objects are provided to an image transfer unit. The image transfer unit is adapted to receive the sorted micro-objects, maintain them in their sorted order and orientation, and deliver them to a substrate. Maintaining the sorted order as the micro-objects are delivered to the substrate may be accomplished through the use of an electrostatic image, as is done in xerography.

Abstract: An addressable imaging belt for use in printing applications having embedded anisotropically conductive addressable islands configured for electric contact on a first side of the belt by a write head consisting of an array of compliant cantilevered fingers with contact pads/points to which a voltage can be applied. The conductive addressable islands electrically isolated from one another and extending substantially through the thickness of the belt in order to allow charge to flow through the belt towards a second side of the belt, in order to form a latent electrostatic image on the second side and develop this latent image by attracting colorized toner or other electrically charged particles to the second side.

Abstract: A printing sub-system including same including a pixilated photoconductive member (such as a photobelt) is disclosed. Electrically isolated cells hold surface application material above the photoconductor. The surface application material is first charged. Charge on the surface application material in an individual cell may then be discharged by exposure of a region of the photoconductor proximate that cell to light from an optical addressing system. The surface application material is brought into proximity of an image receiving member such as paper, which is either charged or proximate a charge source. Charged surface application material in a cell may then be electrostatically transferred from the cell onto the image receiving member, while discharged surface application material remains in the cell. The subsystem may form a part of a complete printing system using many existing components. Among other advantages, viscous liquid surface application material may thereby be printed.

Abstract: An improved fuel cell is described. The invention addresses the problem of mechanical failure in thin electrolytes. One embodiment varies the thickness of the electrolyte and positions at least either the anode or cathode in the recessed region to provide a short travel distance for ions traveling from the anode to the cathode or from the cathode to the anode. A second embodiment uses a uniquely shaped manifold cover to allow close positioning of the anode to the cathode. Using the described structures results in a substantial improvement in fuel cell reliability and performance.

Abstract: Disclosed is a method using a large area flat panel imager which is specifically adapted for rare cell detection methods. The method generally includes an imager having a sample receiving surface which can provide a digital or electronic image of a sample deposited on the surface. The method also includes a selectively positionable microscope and/or camera which are used to obtain high resolution images of the deposited samples. An electronic controller can also be used in conjunction with the imager, microscope, and/or camera to selectively position at least one of those components to focus on desired regions of the deposited sample. The noted method is particularly adapted for use with chemiluminescence or other tagging technologies.

Abstract: An improved method of forming a LED with a roughened surface is described. Traditional methods of roughening a LED surface utilizes strong etchants that require sealing or protecting exposed areas of the LED. The described method uses a focused laser to separate the LED from the substrate, and a second laser to roughen the LED surface thereby avoiding the use of strong etchants. A mild etchant may be used on the laser roughened LED surface to remove unwanted metals.

Abstract: A method of making a curved sensor is described. The method involves projecting portions of a curved three dimensional structure such as a hemisphere onto a two dimensional substrate in an outline pattern. The outline pattern typically serves as a perimeter of a sensor. After forming a sensor in the shape of the outline pattern, the two dimensional substrate is flexed to form a three dimensional sensor structure.
