Abstract: An electronic device includes a first machine body and a second machine body adapted to be detachably assembled to the first machine body. The first machine body includes a first casing, a first hinge fixed to a side of the first casing, a second hinge pivoted to the first hinge along an axis, and a first connecting member disposed at the side and linked to the second hinge. The first and the second hinges are covered by the first casing. The second machine body includes a second casing and a second connecting member. When the first machine body is assembled to the second machine body, the first connecting member is fixed to the second connecting member, the second hinge is fixed jointly so that the first hinge is rotatable related to the second hinge. Accordingly, the first casing is rotatable related to the second casing.

Abstract: The present disclosure relates to methods and systems for synthesis of bridged-hydropentacene, hydroanthracene and hydrotetracene from the precursor compounds pentacene derivatives, tetracene derivatives, and anthracene derivatives. The invention further relates to methods and systems for forming thin films for use in electrically conductive assemblies, such as semiconductors or photovoltaic devices.

Abstract: Concepts and technologies are described herein for progressive loading for web-based spreadsheet applications. In accordance with the concepts and technologies disclosed herein, a user device can access data from a remote source such as a server computer. The user device can determine dimensions of a viewport corresponding to a viewable portion of the data, a window associated with the viewport, and a preloaded area associated with the window. The user device can request the data associated with the window and the preloaded area and store the data in a cache associated with the user device. The cached data can be used by the user device to generate UIs for displaying the spreadsheet. If the user device detects movement of the viewport, the user device can render a new UI in response to the movement. The user device also can be configured to update and/or clean the cache.

Abstract: Concepts and technologies are described herein for row and column navigation. In accordance with the concepts and technologies disclosed herein, a user device executes an application program configured to present data in a user interface (“UI”). The user device can execute a navigation controller to detect touch events at the user device. The navigation controller can determine if touch events correspond to input for panning or scrolling the UIs and for implementing the requested panning or scrolling. The navigation controller can include functionality for providing a touch event handler to detect input for panning or scrolling the data and a UI scrolling manager that implements the requested panning or scrolling. The panning or scrolling can be tracked and the data, as modified in accordance with the tracked movement, can be presented to a user in a UI.

Abstract: Methods for synthesizing 1,4-(ketone or ketal) bridged and/or 5,14-(ketone or ketal) bridged hydropentacenes useful as soluble precursors for formation of pentacene or substituted (e.g., halo) pentacenes; precursor compounds formed thereby; methods for preparing form the precursor compounds conductive thin films comprising pentacene or a substituted pentacene, and articles including such thin films are described. Also described are tetracene and anthracene derivatives which should also be useful in the formation of conductive thin films, among other uses.
