  • Publication number: 20180099333
    Abstract: A method for inspection of 3D manufactured parts or structures or process control of a 3D manufacturing apparatus is provided. The method includes obtaining, in real-time during a 3D manufacturing build process in which at least one structure is built by the 3D manufacturing apparatus, a topographical scan of an area of a build platform on which the at least one structure is built. An evaluating step evaluates, by a processor, the topographical scan to determine a powder depth and/or a layer depth after powder redistribution. A determining step determines based on the evaluating, whether the powder depth or the layer depth is either inside or outside a predetermined range. A modifying step modifies, based on the determining, an operational characteristic of the 3D manufacturing apparatus. The topographical scan is obtained by a laser scan, a blue light scan, a confocal scan or a multifocal plane microscopy scan.

  • Publication number: 20180014260
    Abstract: Systems and methods for dynamic cell breathing for power saving are disclosed. In some embodiments, a method of operation of a radio access node includes determining a target transmit power level from multiple predetermined transmit power levels for the radio access node. The method also includes determining that the current transmit power level should be adjusted to reach the target transmit power level and, in response, adjusting a transmit power level of the radio access node from the current transmit power level to the target transmit power level via multiple transmit power level adjustments. Adjusting the power level of the radio access node via more than one transmit power level adjustment makes it possible to avoid some of the issues with the sleep mode proposal, according to some embodiments.

  • Patent number: 6531413
    Abstract: A method for depositing an undoped silicate glass layer. An undoped silicon glass layer is formed to fill a recessed region in a semiconductor substrate by performing at least three chemical vapor depositions. The recessed region is a trench of a shallow trench isolation, or a gap between a plurality of polysilicon or conductive layers. At each pass, under deposition conditions that are as conventionally defined, this method comprises increasing the number of times of deposition performed on the substrate and decreasing the time of each deposition inside a reaction chamber in order to have the thickness of the undoped silicate glass thinner. In this manner, the gap filling ability is enhanced and void formation is prevented. This method also includes, before each deposition is performed, rotating the semiconductor substrate a given angle in a clockwise or counter-clockwise direction so that by the last deposition, the semiconductor substrate has rotated a total of 360° or a multiple of 360°.
