Abstract: A method of generating documents. In one embodiment the method involves establishing an architecture for a set of rules to be used in documents that consist of a plurality of components and creating a dynamic document structure that can resolve to one or more instances of a document and that is configured to include one or more rules based on the architecture for a set of rules. The architecture for a set of rules may be established by creating a schema having a conditions element, a choose element, an iterators element, a functions elements, and an external interface element that is configured to be resolved into a value. The method may also be configured to create a static document structure that can be resolved to one or more instances of a document that includes at least some content that is determined before and some content that is unchanged during and after a resolution process.

Abstract: A knowledge base configured to store data structure components as objects in an object-relational hierarchy, each object configurable to have precedence, to include one or more rules, and to include content. The knowledge base may be coupled to a data structure assembly facility capable of retrieving one or more data structure components from the knowledge base and generate a tree having a root node, processing the tree beginning at the root node, and overriding objects of low precedence with objects of higher precedence.

Abstract: A vacuum cleaner current-carrying hose connection system is disclosed having a female connection end on a first vacuum cleaner current-carrying hose adapted for receiving a male connection end on a second vacuum cleaner current-carrying hose. The male connection has at least two male receptor plugs configured for inserting into female receptor holes in the female connection end. A vacuum cleaner hose connection system is further disclosed having a male connection end that has at least two male receptor plugs for transmitting current, a female connection end having at least two female receptor holes for receiving the male receptor plugs, and the male and female connection ends being rotatably movable, about the longitudinal axis of at least one of the female connection end and the male connection end, between an unengaged position and an engaged position.

Abstract: The present invention is a board that aids in performing acrobatics and stunts on a trampoline. The board is curved up from a horizontal plane at each end, forming a shallow and elongated U-shape, and is made of lightweight, flexible material. The board has at least one securing member adapted to receive a user's feet.

Abstract: A balanced power amplifier circuit arrangement comprises a driver amplifier stage (22) adapted to receive and amplify a signal. The amplified signal is input to a first coupler (26). The first coupler (26) produces an in-phase signal and an out-of-phase quadrature signal. A first power amplifier (38) receives and amplifies the in-phase signal. A second power amplifier (40) receives and amplifies the out-of-phase signal. A first switch (28) alternately connects an isolated port of the first coupler to ground (32) or a bypass path (36). A second coupler (42) receives and combines the amplified in-phase signal and the amplified out-of-phase signal to produce a combined signal. A second switch (30) alternately connects an isolated port of the second coupler (42) to either ground (34) or the bypass path (36). When the power amplifiers (38, 40) are powered down, the first coupler (26) splits the RF-signal into an in-phase signal and an out-of-phase signal.

Abstract: A method of processing seismic data, for example surface seismic data such as multi-component OBC (Ocean Bottom Cable) seismic data, comprises using vertical seismic profile (VSP) seismic data to determine a model of the relationship between depth within the earth and the velocity of seismic energy. In one embodiment, an model of the relationship between depth and velocity of seismic energy for P-waves is calibrated using VSP seismic data. Then, a model of the relationship between depth and velocity of seismic energy for S-waves is calibrated using VSP seismic data. Initially the models are calibrated for the vertical velocity of P-waves and S-waves, using zero-offset or low-offset VSP data. The models may then undergo further calibration steps, such as calibration for VTI anisotropy and anelastic attenuation. Once calibration is complete, the models are used to process surface seismic data.

Abstract: Power detectors sense load mismatch conditions and cause the power output of a power amplifier to be reduced in response to a load mismatch. Transmitted and reflected power measurements are used to calculate a load mismatch criterion. A power amplifier is configured based on the calculated load mismatch criterion. A dual-directional coupler may be used to separate a power signal into transmitted and reflected components. With output power reduced under load mismatch conditions, signal distortion levels may be reduced to acceptable levels.

Abstract: A stackable wall panel system including at least one upper and lower wall panel and a first and second post. The second post is disposed on the first post. One or more upper wall panels are connected to a pair of lower wall panels having a rail with a pair of draw blocks and a draw rod.

Abstract: A water leak detection apparatus comprises a sensor, a control unit and a valve module. The sensor is adapted to be placed below a water line or coupling. The valve module is positioned as far upstream on a water line as possible. The control unit actuates the valve module and an audible alarm when the sensor detects a water leak. The valve module closes a valve positioned along the water line to restrict flow through the water line until the control unit has been manually reset. The control unit also features a trigger button to allow the valve to be manually cycled for cleaning, for instance.

Abstract: A telephone call reception system which infers mental and/or physiological states of callers. Two types of analysis are available, and both types may be used upon the telephone calls. In one type, speech recognition is performed upon the call to generate a text file. Key words are sought in the text file. In the second type, the electrical signal itself is processed, as by a spectral analysis. Information obtained by the two analyses is used to predict the mental or physiological state of the caller.

Abstract: A stackable wall panel system including at least one upper and lower wall panel, a first and second corner post and an insert. The insert threadably engages an upper portion of the first corner post, and the second corner post is disposed on the first corner post over the insert. A connector connects the second corner post and the insert. One or more upper wall panels are connected to a pair of lower wall panels with an alignment clip, a pair of draw blocks and a draw rod.
