The present invention provides computer systems, methods, and software products enabling the creation and maintenance of disaster recovery volumes having a reduced impact with regard to network traffic over a communications network. A disaster recovery volume is generally created at a local archival storage unit including therein at least one storage medium constituting the disaster recovery volume. The medium constituting the disaster recovery volume is associated with the primary volume thereby allowing the storage medium constituting the disaster recovery volume to be relocated to a remote archival storage unit at a remote location without compromising the association between the primary volume and the disaster recovery volume. Incremental changes to the primary volume may then be communicated and incorporated in to the disaster recovery relocated to the remote location.

An optical see-through (OST) head-mounted display (HMD) uses a calibration matrix having a fixed sub-set of adjustable parameters within all its parameters. Initial values for the calibration matrix are based on a model head. A predefined set of incremental adjustment values is provided for each adjustable parameter. During calibration, the calibration matrix is cycled through its predefined incremental parameter changes, and a virtual object is projected for each incremental change. The resultant projected virtual object is aligned to a reference real object, and the projected virtual object having the best alignment is identified. The setting values of the calibration matrix that resulted in the best aligned virtual object are deemed the final calibration matrix to be used with the OST HMD.

Techniques are disclosed herein for extracting attributes from documents such as web pages. A structure of a training document is compared with a structure of a template to determine a template-node that structurally corresponds to a training-document node that has been annotated with an attribute. Filters can be learned by analyzing characteristics that the attribute possesses in the training document. To extract information for the attribute from a new document, first a set of candidate nodes in a new document are determined by determining which nodes in the new document structurally map to the template node. The filters are applied to eliminate false positives from the candidate nodes. Information can then be extracted from the new document, based on remaining candidate nodes. Even if incremental changes are made to the structure of new documents, nodes that posses the attributes can still be reliably identified.

A system and method employing an allocation process for determining the number of server machines at each tier of a multiple tiered server system. The allocation process evaluates the number of server machines at each tier sufficient to achieve an average response time of a transaction request to be processed by the server system in response to changes in the average number of transaction requests. The allocation process also identifies shadow pricing enabling analysis of the cost associated with incremental changes in the average response time or other critical system resources.

In a method for manufacturing a reflector having a plurality of convex portions 4 that are obtained by means of melt deformation of column-shaped bodys 15 formed of a photosensitive resin material, the photosensitive resin material has aspect ratio vs. average tilt angle characteristics in which an average tilt angle theta reaches a maximum value through an incremental change process and then converges to a certain value through a decremental process when an aspect ratio is gradually increased from a value close to zero, provided that the average tilt angle of the convex portion is an angle of elevation from the outer periphery of the bottom surface of the convex portion 4 to an apex of the convex portion and that the aspect ratio is a ratio of the height of said column-shaped body 15 with respect to the width thereof. A set value for the aspect ratio of the column-shaped body 15 that is obtained after the development step is determined to be a larger aspect ratio than a starting point from which convergence to said certain value begins. This configuration provides a reflector having good contrast characteristics and PAPER WHITE APPEARANCE, and a reflective liquid crystal display panel that uses the above-mentioned reflector.

A mixed text and image layout algorithm capable of supporting Unicode text and arbitrary content definitions for geometric layout with worst case two-pass layout placement procedure. Layout of Unicode text requires a number of distinct processing steps commencing with classification of input characters into contiguous groups of identical directionality, writing system and possibly script (and language) followed by mapping of character groups to glyphs for display purposes followed by a layout taking into account font display characteristics, embedded directionality level and shape of container for layout contents. Layout is best-case achieved in a single layout pass and worst-case in two passes. During layout information is cached to facilitate incremental changes to an existing layout in order to minimize refresh operations for editing display purposes. An optional two-pass operation on the layout result may be used to generate ordered rendering operation to support so-called Z-index display. An optimized Unicode character classification method utilizing reduced memory is also disclosed. Additionally a method to selectively display caret location for mixed font and/or directional text is disclosed.

A trailer backup assist system for a vehicle reversing a trailer, according to one embodiment, includes a sensor that senses a hitch angle between the vehicle and the trailer.

The first controller communicates a ratio control signal to the matching network, and the matching network controls the ratio tuning element in accordance with the ratio control signal. The RF controls system operates in a continuous and pulse mode of operation. The controller can also control the rise or fall of a pulse edge or a level or duration of incremental changes in the pulse edge.

An engine control unit, and method of use, uses a power curve or algorithm to pro-actively adjust fuel flow rate to an engine, optionally in combination with a reactive power curve or algorithm, thereby to adjust engine power, in anticipation of changes in loads being imposed on the engine, as well as to respond to engine speed changes. The ECU has a power curve or algorithm stored in memory which responds to certain predetermined operating conditions other than sensed engine speed, by providing a sequence of pro-active change inputs, at predetermined rates of change, in rate of delivery of fuel to the engine combustion chambers, independent of engine speed change, thereby to produce pro-active incremental changes in power output of the engine. Such pro-active incremental power changes are effected in anticipation of changes in load demand on the engine, and correspond generally with expected incrementally progressive changes in load demand on the engine. In preferred embodiments, the power curve or algorithm includes a first upwardly sloping line representing small increment increases in engine power, a second step change increase in engine power, a third downwardly sloping line representing small incremental decreases in engine power, and a fourth relatively greater magnitude step change decrease in engine power. The pro-active change input signals can be combined with reactive change input signals to make respective combination change input signals which take into consideration a variety of operating parameters, including engine speed changes.

A method for synchronizing a time architecture of a mobile network that includes a plurality of network components, each having a time subsystem clock that is updated using a network time protocol (NTP) program. The method includes operating the components in a hierarchical fashion and booting up all the network components such that execution of a NTP sub-program for making small incremental changes to the each component time subsystem clock is delayed. Additionally, the method includes iteratively executing a NTP sub-program for making large changes to each component time system clock until each component time sub-system clock establishes an initial synchronization with a parent component time sub-system clock. Furthermore, the method includes iteratively executing the NTP sub-program for making small incremental changes once initial synchronization is established such that each component time sub-system clock maintains synchronization with the parent component time sub-system clock.

Energy management methods and systems based on financial impact are disclosed herein, wherein an energy management system at a site monitors metered energy consumption, establishes a peak consumption level, determines whether energy consumption will result in an increased peak consumption level, and if it will, calculates the financial value and costs of mitigating an increase in the peak consumption level, including an increase in demand charge prospectively avoided, and mitigates the peak in consumption to the peak consumption level using an energy storage system or other energy providing device if the value of mitigating the peak offsets the inherent costs. Embodiments may further use confidence factors or incremental changes to a peak consumption level to optimize the process and utilize energy devices to their greatest effectiveness.

Techniques for conducting a promotion of a product or service, managing various promotion activities, and rewarding promotion partners are disclosed. An incremental sales (e.g., incremental sales volume, revenue, and profit) analysis due to a promotion is performed and a fee is assessed based on a result of the incremental sales analysis. In some embodiments, performing the incremental analysis includes assigning to a control group a first subset of a plurality of target customers associated with the promotion, assigning to an offer group at least a second non-overlapping subset of the plurality of target customers, providing to at least the offer group but not to the control group an offer associated with the promotion, and determining an incremental change in sales of the product contributed by the customers in the offer group—as compared to sales contributed by the customers in the control group. In some embodiments, performing the incremental sales due to the promotion is determined based on a difference between a maximum allowable discount and an actual discount for individual customers.

Two methods for determining a best initial heading estimate for use in an AINS system, while recording position data values and in-motion data values, assigning incremental changes to indexed heading ψ_k, calculating a set of time indexed present AINS position values and a corresponding set of time indexed absolute horizontal position measurement residual values, recording the absolute maximum time indexed horizontal position measurement residual and the corresponding value of ψ_k returning to the step of assigning an incremental increase to a next value to indexed heading ψ_k up to 360 degrees, identifying the maximum time indexed horizontal position measurement residual and corresponding ψ_k, followed by identifying the ψ^k having the smallest absolute maximum horizontal position measurement residual as A_k Second method uses a circular array of AINS ENGINES each with a different ψ_k running in parallel and finding smallest horizontal position measurement residual for A_k.

A method for using a change-recording feature to perform more effective backups includes generating an initial point-in-time copy of source data residing in a storage device. The method may then perform an initial backup of the initial point-in-time copy. As changes are made to the source data, the method may record changes made to the source data after the initial point-in-time copy is generated. These changes may be stored as incremental change data. At some point, the initial point-in-time copy may be updated using the incremental change data. In order to perform an incremental backup of the updated point-in-time copy, the method may query the incremental change data to determine which changes were used to update the point-in-time copy. The method may then perform an incremental backup of the updated point-in-time copy by backing up the changes designated in the incremental change data.

The invention discloses a dynamic monitoring method for measuring landslide stability by means of rainfall. The method comprises the following steps: enabling the ratio of the incremental change of rainfall and initial rainfall in a precipitation process to be a dynamic loading rate of landslide instability; enabling the ratio of the change of corresponding landslide displacement rate and the initial displacement rate to be a displacement dynamic response rate of the sliding stability; enabling the ratio of the dynamic loading rate of the landslide instability and the displacement dynamic response rate to be defined as a landslide displacement dynamic loading rate; confirming rainfall dynamic loading rate predictive parameters of a landslide with displacement rainfall dynamic loading rate of the landslide as a criterion of the landslide stability; constructing a landslide stability evaluation model according the quantitative relationship between the rainfall dynamic loading rate predictive parameters and the landslide stability; and evaluating and forecasting the landslide stability. According to the dynamic monitoring method for measuring the landslide stability by means of the rainfall, the rainfall and the landslide displacement or the displacement rate are simultaneously monitored. In addition, the dynamic monitoring method for measuring the landslide stability by means of the rainfall has the precise unified criterion for forecasting the landslide, and supplies effective evidence to landslide forecasting and early warning management.

Provided is an architecture that eliminates the need for on-disk full backups of data retaining only changes that have occurred, in a separate table. Thus, the architecture provides for incremental recovery of incremental changes in a relational database (e.g., SQL). The architecture provides improved recovery time and recovery point objectives. By using the incremental capture of changed data (e.g., in an XML format), the capability is provided to capture schema changes, query the incremental change data and efficiently restore user data to an earlier point-in-time state. Changes (e.g., insert, update and delete operations) are tracked (e.g., continuously) by a set of triggers and the incrementally captured changed rows are inserted in a data capture table (a differential change ''delta'' table) in a human-readable format (e.g., XML). Rollback is also provided.

A low leak pressure control actuator for, e.g., controlling pressure in an automatic transmission system, includes a poppet and a check ball slidably disposed within a housing. The poppet and check ball are movable between a de-energized configuration, plural partially energized configurations, and a fully energized configuration. In the de-energized configuration, the poppet and check ball prohibit all flow to and from the supply port and permit flow between the control port and the exhaust port. In the partially energized configurations, the poppet and check ball permit flow to and from all of the ports, and incremental changes in the internal displacement of the poppet produce incremental changes in a control pressure. In the fully energized configuration flow, the poppet and check ball prohibit all flow to the exhaust port and permit fluid flow between the supply port and the control port.
