Abstract: An optoelectronic device has a layered construction, comprising a base layer, a first conductive layer, a photoactive layer and a second conductive layer. Plural separation channels extending through the photoactive layer and the first conductive layer separate the photoactive layer into photoactive regions, and insulator material extends through the respective separation channels to the base layer. Between adjacent photoactive regions, electrical connectors extend inside the lateral extent of the insulator material between a surface of a second electrode that is in electrical contact with one photoactive region to an opposing surface of a first electrode that is in electrical contact with the other photoactive region. By forming the electrical connectors extend inside the lateral extent of the insulator material, the overall size of the connection is minimized.

Abstract: A manually operable herb grinder features a housing assembled from a plurality of detachable sections, including a drive section for housing drive components and one or more product chamber sections for containing a product. The product chamber is divided into input and output chambers for initially receiving unground product, and catching ground product falling from a grinding area intermediate the two chambers. Blades carried on a shaft in the grinding area are rotated by a planetary gear system, whose input is a rotatable cap installed over the drive section at a top end of the housing. The grinding area is situated between a spoked divider at an upper end of the input chamber, and a perforated divider at the upper end of the output chamber. The cap is rotatable by hand, or by frictional rolling contact against a surface.

Abstract: Described herein are embodiments of systems and methods for oxidizing gases. In some embodiments, a reaction chamber is configured to receive a fuel gas and maintain the gas at a temperature within the reaction chamber that is above an autoignition temperature of the gas. The reaction chamber may also be configured to maintain a reaction temperature within the reaction chamber below a flameout temperature. In some embodiments, heat and product gases from the oxidation process can be used, for example, to drive a turbine, reciprocating engine, and injected back into the reaction chamber.

Abstract: A method of selectively eliminating electrical shorts and other electrical defects from specific layers of a multilayer electronic device without damaging underlying layers. The method is based on a combination of an automated detection of the defects and selective laser ablation patterning (SLAP).
