International Classification:

H01L 31/0216
B05D 5/12

US Classification:

136256, 427 74

Abstract:

A multilayer conformal coating is optimized in both composition and geometry to protect the back and sides of a transparent-fronted thin-film solar photovoltaic panel or similar device from various damage mechanisms associated with long-term outdoor exposure without an additional backcap or edge frame. A “barrier stack” or “barrier layer” of inorganic moisture-barrier and chemical-barrier layers is applied to the back of the photovoltaic functional film stack, extending into a bare-substrate border zone around the functional stack edges. The barrier stack shields the functional stack from moisture and chemical invasion, and the coated border zone effectively seals the vulnerable edges of the functional stack. An “envelope stack” or “envelope layer” of thicker polymer films is applied over the mechanically delicate inorganic barrier stack and around the solar photovoltaic panel edges. The envelope stack electrically insulates the solar photovoltaic panel and substantially protects the panel back and sides from mechanical shock, stress, and abrasion, thermal stress, fire, weathering, and UV-exposure degradation.

Philip Liu - Fremont CA, US

International Classification:

G01N 27/04

US Classification:

324693

Abstract:

An apparatus and method is provided for determining, using real-time data, whether a removal process has been effective in removing a conductive coating from a removal site on a substrate of an electric device. The method includes determination of conductivity between the removal site and the intact conductive coating which relates to the absence or presence of the conductive coating in the removal site. The presence of conductive coating in the removal site indicates incomplete removal and thus enables real time correction thereof.

International Classification:

F41A 33/02
F41A 31/02

Abstract:

A simulation laser training cartridge for dry-firing practice adapts to the wear condition of a given firearm and provides a convenient way of measuring the barrel erosion. The cartridge uses multiple adjustable interfacing parts that can be applied selectively and independently according to the condition of the barrel to ensure a snug fit in 3-dimensions. In a 2-unit kit embodiment of the invention, the muzzle unit can work with multiple chamber units for a multi-chamber firearm. The cartridge also includes internal modules for laser property management, status monitoring, movement tracking, memory, and communication to help a user manage the device and allow for advanced training applications. By changing the laser property, the laser training cartridge can work as a bore sight. The cartridge may further include a means to attach an external part, so the external part comprises a means to distinguish a longitudinal position inside said barrel.

Abstract:

A computerized interactive learning system includes a display device and a compatible input device. The display device provides work items to a learner. The input device detects input activities from the learner in response to the work item. The system analyzes the input activities at two or more tiered levels of granularity. The display device provides conditional feedback to the learner based on the analysis. The input device and the display device can be incorporated into an integrated touchscreen.
