| 20100003812 | Solar Cell Fabrication Using Extrusion Mask - Large-area ICs (e.g., silicon wafer-based solar cells) are produced by positioning a mask between an extrusion head and the IC wafer during extrusion of a dopant bearing material or metal gridline material. The mask includes first and second peripheral portions that are positioned over corresponding peripheral areas of the wafer, and a central opening that exposes a central active area of the wafer. The extrusion head is then moved relative to the wafer, and the extrusion material is continuously extruded through outlet orifices of the extrusion head to form elongated extruded structures on the active area of the wafer. The mask prevents deposition of the extrusion material along the peripheral edges of the wafer, and facilitates the formation of unbroken extrusion structures. The mask may be provided with a non-rectangular opening to facilitate the formation of non-rectangular (e.g., circular) two-dimensional extrusion patterns. | 01-07-2010 |
| 20100143581 | Micro-Extrusion Printhead With Nozzle Valves - A solar cell extrusion printing system includes a printhead assembly having one or more elongated valve structures that are adjustably disposed adjacent to the outlet orifices of selected nozzle channels, and a valve control device for controlling the position of the valve structures to facilitate controllable ink flow through selected nozzle channels of the printhead assembly during the gridline printing process. The printhead assembly defines an elongated opening (e.g., a slot or hole) that that intersects (i.e., passes through) each of the selected nozzle channels, and an elongated member is movably disposed in the slot and is selectively movable between a first (opened) position, in which the valve structure extrusion material is passed by the valve structure through the nozzle channel and out of the printhead, and a closed position, in which the extrusion material is blocked by the valve structure and prevented from passing through the nozzle channel. | 06-10-2010 |

| 20080277885 | Wiring-Free, Plumbing-Free, Cooled, Vacuum Chuck - A solar cell production system utilizes self-contained vacuum chucks that hold and cool solar cell wafers during transport on a conveyor between processing stations during a fabrication process. Each self-contained vacuum chuck includes its own local vacuum pump and a closed-loop cooling system. After each wafer is processed, it is removed from its vacuum chuck, and the vacuum chuck is returned to the start of the production line by a second conveyor belt. In one embodiment, each vacuum chuck includes an inductive power supply that is inductively coupled to an external source to drive that vacuum chuck's vacuum pump and cooling system. An optional battery is recharged by the inductive power supply, and is used to power the vacuum pump and cooling system during hand-off between adjacent processing stations. | 11-13-2008 |

| 20090244013 | ELECTRONIC DEVICE AND TACTILE TOUCH SCREEN DISPLAY - An electronic device includes a housing with a back and a frame. A support tray is spaced from the back and includes a tray base, and a lip connected to and spaced from the tray base. The support tray supports a display device and touch-sensitive overlay disposed on the display device. A plurality of pads on an exterior of the support tray include pads between the tray base and the back and pads between the lip and the frame. Operational components are housed in the housing and include a touch screen controller connected to the touch-sensitive overlay and a processor connected to the display device and the touch-screen controller. | 10-01-2009 |
| 20090296341 | ELECTRONIC DEVICE AND TACTILE TOUCH SCREEN DISPLAY - An electronic device includes a housing having a back, a support tray moveable relative to the back of the housing, a touch-sensitive display supported by the support tray and moveable with the support tray relative to the back of the housing, the touch-sensitive display including a display device and a touch-sensitive overlay disposed on the display device, a locking arrangement cooperating with the support tray for locking the support tray and touch-sensitive display to inhibit movement of the support tray relative to the back of the housing, and operational components housed in the housing and including a touch screen controller connected to the touch-sensitive overlay and a processor connected to the display device and the touch-screen controller. | 12-03-2009 |
| 20090323264 | ELECTRONIC DEVICE AND TACTILE TOUCH SCREEN DISPLAY - A portable electronic device includes a housing having a touch-sensitive display moveable relative to the housing and a locking plate that inhibits movement of the touch-sensitive display relative to the housing. | 12-31-2009 |
