Abstract: Methods are disclosed for nondestructive testing and measuring the structural health of prestressed concrete structures, such as slabs, columns, girders, bridges, towers, elevated storage tanks, silos, cooling towers, wind power generation towers, liquefied gas storage tanks, nuclear power containment buildings, and the like. Measurements are made as the structure undergoes tensioning and detensioning operations. By measuring actual movements of cardinal points on the structure, in an absolute three-dimensional coordinate system, and comparing the measurements to a model—as tension on a tendon is changed—a margin of safety is assured. High accuracy measurements are made by electronic distance measurement (EDM) instruments over hundreds of meters, which yield coordinates of cardinal points with an uncertainty of the order of one part per million.

Abstract: A two-dimension layout system identifies points and their coordinates, and transfers identified points on a solid surface to other surfaces in a vertical direction. Two leveling laser light transmitters are used with a remote unit to control certain functions. The laser transmitters rotate about the azimuth, and emit vertical (plumb) laser planes. After being set up using benchmark points, the projected lines of the laser planes will intersect on the floor of a jobsite at any point of interest in a virtual floor plan, under control of a user with the remote unit. An “active target” can be used to more automatically create benchmarks. A laser distance meter can be installed on base units to automatically scan a room or a wall to determine certain key features.

Abstract: A power distribution and communication system includes nodes connected by power lines and communication links. The system receives power from one or more power sources. Each node contains at least one power port, data port and load port. Associated with each power port and load port is a port monitor for measuring current flowing into or out of the port and the voltage difference between the port outlet and ground, which measurements are passed to a processing element. The processing element and monitor analyze measured values to detect fault conditions. Upon fault condition detection, the port is disabled by opening a switch, disconnecting the port from the system voltage. The processing element receives power directly from the power line, thus receiving power from a live power line even if the associated power port is disabled allowing the processing element to enable a disabled node following a failure.

Abstract: Systems and techniques are provided for measuring consistency of animation and/or video rendering on a device, and providing a user with an indication of one or more consistency scores of the user's device. The consistency score indicates generally the consistency of user experience that is expected for the user device. In some cases, the consistency score is calculated based upon the differences in rendering times between adjacent frames in an animation, and/or the number of frames that have a render difference that differs from a standard or baseline value. A consistency score also may be based upon the framerate achievable by the device when rendering a video at a constant quality.

Abstract: An economizer controller with sensor calibration. A controller sensor may be used to measure a parameter. At the same time at the same location of the measurement with the controller sensor, a measurement of the same parameter may be made with a precision sensor. The difference between the two measurements may be saved to a controller memory as an offset. The offset may be used to compensate future measurements of the same parameter by the controller sensor. Additional offsets at various magnitudes may be obtained between the precision and the controller sensors for compensating subsequent measurements by the controller sensor. Measurements with the compensated sensor may be used for calibrating sensors in other economizer controllers, for example, at remote locations in the field.
