摘要:
A computer-readable medium includes a report generator configured to process a current version of a data set to generate a report including a data item. The computer-readable medium also includes a report data change tracker configured to identify a change in the data item with respect to a previous version of the data set. The computer-readable medium further includes a report data change presenter configured to superimpose an indication of the change onto the report.
摘要:
A computer readable medium includes executable instructions to form a report; process trust values, where each trust value characterizes the accuracy of an attribute of the report; combine trust values to provide an aggregate trust value associated with the report; and supply a user with the report and the aggregate trust value.

A silt and debris catching apparatus comprises a housing component and a catchment component. The housing component is adapted to fit within a valve box assembly. The catchment component is coupled to the housing component and includes a filter. The filter retains material that enters the valve box assembly.

Systems and methods are provided to implement a technique for providing 3D content, such as on optical media like Blu-ray® discs. In one implementation, a 3D authoring tool executing on a computer system manages how to construct an image for replication where the image handles jumps without buffer underruns, the jumps caused by layer switching or by moving from or to branches in a multi-branch story line.

A security alarm monitor is disclosed that uses a combination of three dimensional (3D) and two dimensional (2D) visualization to display the status of security devices and allow the operator to respond to alarms. The alarm monitor console includes 3D and 2D display areas, either in a split screen on a single monitor or on dual monitors. The 3D display area uses a photo-realistic representation of a facility and overlays iconic or 3D representations of the security devices showing their locations, coverage areas, and alarm status. The 2D display area shows a map, architectural drawing, image-based overhead view, or combination or the three for a facility and security device icons. The alarm representations in the 2D and 3D display areas are synchronized. The 3D display gives a dynamic view of the facility or compound. When an alarm occurs, the 3D display flies to preprogrammed view of the alarm location, issues a preprogrammed audio alert, and animates the alarm icon to indicate its status.
摘要:
Shims used to join part assemblies are automatically designed and fabricated without the need for fitting part assemblies together in order to determine the exact dimensions of voids filled by the shims. The locations of key features on part assemblies are surveyed using a merged photogrammetry and laser tracking technique that generate the dimensions of a virtual shim. The dimensions of the virtual shim are contained in a digital file that can be used to automatically fabricate the shim using automated fabrication equipment such as a CNC machining center. The automated virtual shim design may be modified to reflect the effect of part assembly fit on performance characteristics of the aircraft.

A convertible tow dolly supported upon a towing vehicle when in an elevated and non-use position. The dolly includes an elongated tubular support having a first end pivotally secured to a first bracket fixedly engaged to a hitch associated with a towing vehicle. A wheeled and crosswise extending portion exhibits a secondary bracket which is pivotally secured a second end of the elongated tubular support and which is locked into position to prevent up and down articulation relative to the brackets and for supporting a towed vehicle upon the crosswise extending portion in a use position. The elongated support is unlocked at the brackets, such as by removal of first and second clevis pins, to permit folding about the first and second pivotal connections and in a direction towards the towing vehicle, concurrent with elevating the wheeled and crosswise extending portion to a subsequently locked and non-use position.

Provided is an apparatus and method for providing differential protection for a phase angle regulating transformer having a load side and a source side in a three-phase power system. The method includes calculating a first positive sequence component and a first negative sequence component associated with incoming secondary currents detected on the source side, calculating a second positive sequence component and a second negative sequence component associated with outgoing secondary currents detected on the load side, applying a phase angle shift to the second positive sequence component and the second negative sequence component to form a compensated positive sequence component and a compensated negative sequence component, respectively, and determining an operate current value and a restraint current value for each of a positive and negative sequence differential element of the differential protection based on the compensated positive sequence component and the compensated negative sequence component.
