Abstract: A spreadsheet supports formulas in cells that trigger queries of a data source. The parameters for queries can include or depend on values in other cells in the spreadsheet. Thus, the precise query submitted to the data source is dynamic, being dependent on the data and formulas in the spreadsheet. Furthermore, on receiving the query results, they are added to cells in the spreadsheet, which can be parameters for other queries defined in other cells. Changing the value of a single cell can automatically trigger an update of an arbitrarily deep hierarchy of calculations that can include an arbitrary number of data source queries.

Abstract: A subsurface representation that includes geometry and material properties of subsurface geological formations may be generated. To compute the initial (pre-production) state of stress, gravitational forces and tectonic forces may be applied to the subsurface representation. These loads may result in stress and displacement fields within the subsurface representation. The stress field may be calibrated against available measurements. At this point, the subsurface representation may be reinitialized by resetting the displacements within the subsurface representation while maintaining the stress field.

Abstract: A system for additive manufacturing machine energy beam alignment error compensation includes, a calibration table having x-y planar offsets to correct laser alignment errors representing energy beam positional offsets between beam-steering commanded energy beam locations and fiducial marks generated on a burn-paper, a recoater mechanism that distributes successive layers of powder, one or more sensors monitoring the powderbed surface proximal to the beam scan unit, and a processor unit configured to perform a method. The method including collecting sensor data representing height variations across at least a portion of the powderbed surface, deriving dimensional data from the collected data, analyzing the dimensional data to determine a distribution of differences between the powderbed surface and a calibration plane used for a first spatial calibration, and calculating z-axis calibration offset points for inclusion in the calibration table x-y planar offsets.

Abstract: A spreadsheet supports formulas in cells that trigger queries of a data source. The parameters for queries can include or depend on values in other cells in the spreadsheet. Thus, the precise query submitted to the data source is dynamic, being dependent on the data and formulas in the spreadsheet. Furthermore, on receiving the query results, they are added to cells in the spreadsheet, which can be parameters for other queries defined in other cells. Changing the value of a single cell can automatically trigger an update of an arbitrarily deep hierarchy of calculations that can include an arbitrary number of data source queries.

Abstract: An LED light fixture having an inexpensive camera or sensor is disclosed. The LED light fixture utilizes a controller that is configured to turn the LED light on and/or adjust brightness of the LED in response to motion only within a perimeter programmed into the controller. This perimeter can be defined by known light output of known LED lenses. The ability to program light detection to be only within a given perimeter allows for the use of generic sensors, such as fisheye cameras, with varying lenses and LED bulbs to provide a lower cost option in motion sensing technology.

Abstract: An LED array having a driver connected to a sensor. The sensor can be either integral with a controller or separate from the driver and in communication with the controller. The sensor is configured to sense one or more of the temperature, forward voltage, LED voltage, and/or total driver power. The controller is preferably configured for wireless connectivity with a local computer, such as by Bluetooth® or configured for an internet connection to allow for remote monitoring of the LED array. The controller can be configured to compare the sensed voltage, temperature, forward voltage, and/or driver power and compare it to a programmed and/or sensed base and notify of a fault. Alternatively, the controller can be connected to a computer via internet and/or wireless signal (such as Bluetooth®) to compare the sensed condition to a normal condition to determine if a fault has occurred.

Abstract: A component includes a body, and an interface in the body defining a first and second portion of the body made by different melting beam sources of a multiple melting beam source additive manufacturing system during a single build. The component also includes a channel extending through the body. The channel includes an interface-distant area on opposing sides of the interface, each interface-distant area having a first width. The channel also includes an enlarged width area fluidly communicative with the interface-distant areas and spanning the interface, the enlarged width area having a second width larger than the first width. Any misalignment of the melting beams at the interface is addressed by the enlarged width area, eliminating the problem of reduced cooling fluid flow in the channel.

The pre-build distance may be determined using the measurement device(s).
