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: A protective cover support rack for electronic devices includes at least a protective cover body, a support lid and a hinge assembly. The protective cover body has an inner rim with an annular U-shaped trough formed thereon to hold and encase the body of an electronic device, and a lower half portion to cover the back side of the electronic device. The hinge assembly includes two hinge means each has one end fastened to one lateral side of the protective cover body and another end fastened to the bottom side of the support lid. Thereby the support lid can be adjusted at an angle smaller than 360 degrees to allow users to swivel to the front side as required to protect the screen of the electronic device, or adjust to a standing position to facilitate viewing, or fold it to fully in contact with back side of the protective cover body at a storing position, or swivel to facilitate hand grasping in use, thus provide diversified usages and improve practicality.

Abstract: A method for correcting typing errors according to character layout positions on a keyboard which consists of depressing responsive touch panels to do character entry to correct typing errors caused by mistakenly hitting a neighboring key of a targeted character due to a swerved typing position includes at least the steps of: (1) corresponding a character; (2) calculating a swerved amount; (3) selecting a prepared character; (4) determining whether input is finished; (5) judging rules; (6) getting the prepared character; and (7) switching the character. Through this method input accuracy can be improved and input characters can be automatically amended as desired.

Abstract: A wide-angle double-hinge structure to allow an electronic device to flip at different angles includes a coupling plate, a resistant hinge and a cam hinge. The double-hinge structure couples a first chassis and a second chassis of the electronic device to enable users to selectively flip in an ordinary notebook computer operating condition or a back-to-back operating condition according to their preference. Thus the users can selectively perform input operation in a handheld or desktop fashion.

Abstract: An XML schema is compiled into an annotated automaton encoding, which includes a parsing table for structural information and annotation for type information. The representation is extended to include a mapping from schema types to states in a parsing table. To validate a fragment against a schema type, it is necessary simply to determine the state corresponding to the schema type, and start the validation process from that state. When the process returns to the state, fragment validation has reached successful completion. This approach is more efficient than a general tree representation. Only the data representation of the schema information is handled, making it much easier than manipulating validation parser code generated by a parser generator. In addition, only one representation is needed for schema information for both document and fragment validation. This approach also provides a basis for incremental validation after update.

Abstract: Techniques are provided that determine that a query includes at least one subquery that may be correlated or decorrelated. An internal representation of the query that represents the subquery in both correlated and decorrelated form is generated, wherein the internal representation includes at least one virtual table.

Abstract: An operation method for a trackpad equipped with pushbutton function aims to control operation of a screen in a cursor movement mode or a button input mode by detecting finger touch conditions on a trackpad. The method is adopted on a trackpad apparatus consisting of a touchpad movable up and down and a pushbutton located beneath the touchpad. The touchpad has at least one cursor zone and one button zone that are incorporated with the operation method to get conditions of the finger and the touchpad. The method includes at least the steps of: a. the finger touches the cursor zone and performs depressing or release depressing action to function as a cursor control command; b. the finger touches the cursor zone and slides into the button zone to do depressing or release depressing action to function as the cursor control command; c. the finger touches the button zone and slides into the cursor zone to do depressing or releasing depressing action to function as the cursor control command; d.

Abstract: A touch control click structure includes at least an action board swayable up and down, a click switch and a touch panel. The action board has an axle mechanism at one end that is fastened to a chassis in an integrated manner, an extension zone in a middle portion and a click zone at another end that is swayable. The click switch aims to control input movements and is located below the action board. The touch panel is located above the click zone. The extension zone is formed at a desired length such that any position of the click zone can get a depressing pressure approximate to each other when depressed. Therefore the click zone can be swayed steadily up and down.

Abstract: A keyboard having multi-axis balance touch keys and particularly a keyboard equipped with touch keys aims to provide steady depressing operation. Each touch key includes a depressible plate, a contact switch, a base and a plurality of balance elements. The balance elements are arranged in two different axial directions and latched respectively on first retaining elements located on the depressible plate and second retaining elements located on the base. The first and second retaining elements have respectively at least one horizontal slot to allow the balance elements to slide therein parallel with the depressible plate. Thus downward depressing forces can be evenly distributed and a steady depressing movement is achieved wherever the touch keys is depressed. Swaying of the touch keys can be prevented and correct output signals can be delivered from the keyboard.
