Abstract: A head up display for a vehicle uses an anti-peep film to limit the optical image from the display module to be projected along a predetermined path, and the HUD is particularly designed so that the driver just can see the optical image displayed on the windshield without being able to see the optical image displayed on the display module. The use of the anti-peep film can reduce the brightness of the optical image projected from the display module. Therefore, a brightness-enhancement module is used to enhance the brightness of the optical image projected from the display module, so as to ensure that the optical image projected onto the reflection film from the display module can be clearly seen. Moreover, a first light source below the light guiding layer of the backlight module to substantially enhance the brightness of the optical image projected from the display module.

Abstract: A method and system for providing a scalable storage scheme for native hierarchically structured data of relational tables, includes a base table with indicator columns with information pertaining to hierarchically structured data of a document, data tables for storing the hierarchically structured data corresponding to the indicator columns, and node identifier indexes corresponding to the data tables for mapping between the indicator columns and the hierarchically structured data in the data tables. In an embodiment, actual data for each hierarchically structured data (such as XML) column is stored in a separate data table, and each data table has a separate node identifier index. The node identifier index is searched with a key containing the document identifier and a logical node identifier is used, and a record identifier of a record in the data table containing the node assigned the logical node identifier is retrieved.

Abstract: A storage of nodes of hierarchically structured data uses logical node identifiers to reference the nodes stored within and across record data structures. A node identifier index is used to map each logical node identifier to a record identifier for the record that contains the node. When a sub-tree is stored in a separate record, a proxy node is used to represent the sub-tree in the parent record. The mapping in the node identifier index reflects the storage of the sub-tree nodes in the separate record. Since the references between the records are through logical node identifiers, there is no limitation to the moving of records across pages, as long as the indices are updated or rebuilt to maintain synchronization with the resulting data pages. This approach is highly scalable and has a much smaller storage consumption than approaches that use explicit references between nodes.

Abstract: An asymmetrical resistant hinge set includes at least a resistant hinge and an elastic element coaxially positioned. The resistant hinge is hinged on a first pivotal means located on the bottom side of a body. The elastic element provides action forces on the resistant hinge and one-way resistance to generate an asymmetrical hinge effect with a greater resistance in one direction and a smaller resistance in another direction when a support lid is flipped in forward and reverse directions to reduce the resistance of the resistant hinge. As a result, when the support lid is flipped to a selected angle it still can bear the weight of the body of a portable electronic device at the anchored position without drifting.

Abstract: An object holding table comprising a table top, a frame body, two rotating shaft sets and a foot stand set. The rotating shaft sets are used to movably attach the table top and the frame body to allow the table top to turn 90 degrees.
