Abstract: An air spring includes a first body; a first piston cooperating with the first body to define a pressurized first chamber including a gas, the first piston configured to slideably move relative to the first body; a pressurized second chamber; a flow passage between the first chamber and the second chamber; and a seal to selectively permit or restrict flow between the first chamber and the second chamber depending on a position of the first piston with respect to the first body.

Abstract: An example vehicle includes a battery tray that is movably coupled to a front axle assembly of the vehicle. A back end of the tray is coupled to a first chassis member and a second chassis member of the vehicle via respective joints that allow rotational motion of the tray with respect to the first chassis member and the second chassis member. The vehicle's chassis includes a first rail comprising a first plurality of holes and a second rail comprising a second plurality of holes. The first rail slides within the second rail to provide an adjustable wheel-base length or width for various configurations of the vehicle. When the first plurality of holes and the second plurality of holes are aligned, one or more fasteners may be used to secure the first rail to the second rail to select a particular wheel-base length or width.

Abstract: Embodiments of systems, methods and apparatuses for a parser for generating one or more data structures representative of a structured document are disclosed. More specifically, embodiments of a parser may comprise hardware circuitry operable to receive a structured document, begin parsing the structured document as it is being received and generating the data structures representative of the structured document as it is being parsed.

Abstract: A guided vehicle relocation device has a frame. The frame has an opening to allow one or more wheels of a vehicle to enter an interior area of the frame. At least one drive mechanism is coupled to the frame. The drive mechanism engages the wheel of the vehicle, rotating the wheel of the vehicle to move the vehicle. A control panel is coupled to the frame and to the at least one drive mechanism. The control panel is used for controlling operation of the guided vehicle relocation device.

Abstract: Embodiments of systems, methods and apparatuses for an architecture for the processing of structured documents are disclosed. More specifically, embodiments of the architecture may comprise hardware circuitry operable to parse a structured document and transform the document according to a set of transformation instructions to produce an output document.

Abstract: Embodiments of systems, methods and apparatuses for an output generator for generating output from processed content of a structured document are disclosed. More specifically, embodiments of an output generator may comprise hardware circuitry operable to order data resulting from the transformation of a structured document as it is generated and format this data according to a format of a corresponding output document to generate output corresponding to the output document.

Abstract: An apparatus comprises a stylesheet compiler and a document processor. The stylesheet compiler is configured to identify expressions in a stylesheet and is configured to generate one or more expression trees representing the expressions. Expressions having one or more common nodes are represented as children of a subtree that represents the common nodes. Coupled to receive a document and the expression tree, the document processor is configured to evaluate the expressions represented in the one or more expression trees against the document.

Abstract: An apparatus comprises a parse circuit and an expression processor. Coupled to receive a document, the parse circuit is configured to parse the document and generate events corresponding to the parsing. Coupled to receive the events from the parse circuit, the expression processor is configured to apply nodes identified by the events to one or more expression trees derived from a plurality of expressions in a stylesheet. The expression processor identifies nodes that satisfy the expressions represented in the one or more expression trees as a result of applying the nodes to the one or more expression trees. A method is contemplated. Each expression in a stylesheet is characterized as evaluatable at one of a plurality of phases of applying the stylesheet to a document in a document transformation appliance. Each expression is applied to the document in the one of the plurality of phases determined in the characterizing.
