Abstract: An inlet manifold is for use in a laser powder bed fusion system having a build platform for carrying a powder bed and a pump or blower for supplying a gas flow in a direction relative to a surface of the build platform. The inlet manifold is made of a gas flow guide structure having a gas flow inlet to receive the gas flow and being comprised of a plurality of stacked gas flow guides, each being defined by top and bottom guide plates oriented downwards at an angle A relative to the direction of the gas flow for guiding the gas flow downwards towards a gas flow outlet. At least some of the top and the bottom guide plates have upwardly curved ends at the gas flow outlet to redirect the gas flow to be substantially parallel to the surface of the build platform.

Abstract: The present disclosure is directed toward systems and methods for fingerprinting wireless communications using few-shot learning techniques. The systems and methods relate to storing fingerprint data indicating device fingerprint features detected for a plurality of identified transmitting devices in a database. The methods further relate to receiving, at a communication device, wireless communications from an unidentified transmitting device. Additionally, the systems and methods illustrate determining a device fingerprint responsive to a portion of each of the wireless communications using few-shot learning techniques and comparing the determined device fingerprint to the stored fingerprint data in the database.

Abstract: Systems and methods are provided for risk management in an expert system. A distribution of feature values within a training dataset for the expert system and each of a plurality of baseline datasets are determined, and Kullback-Leibler divergences between the baseline dataset and the training dataset to provide set of Kullback-Leibler divergence values. Measures of central tendency and statistical dispersion of the set of Kullback-Leibler divergence values are determined, and a threshold Kullback-Leibler divergence value is determined from these values and a desired confidence interval for new datasets. A Kullback-Leibler divergence value between the feature values of novel dataset and the training dataset is determined and it is determined that the second dataset represents an unacceptable divergence if this Kullback-Leibler divergence value exceeds the threshold value.

Abstract: An exemplary RF module includes a dielectric substrate with metal traces on one surface that connect high frequency components and provide reference ground. Other metal traces on the other surface of the substrate also provide high frequency transmission lines and reference ground. An enclosure made using semiconductor manufacturing technology is mounted to the substrate and has conductive interior recesses defined by extending walls that are connected to the reference ground. The recesses surround the respective components and provide electromagnetic shielding. The dimensional precision in the location and smoothness of the walls and recesses due to the semiconductor manufacturing technology provides repeatable unit-to-unit RF characteristics of the RF module. One way of mounting the enclosure to the substrate uses a plurality of metal bonding bumps extending outwardly from the walls to engage reference ground metal traces on the substrate. Applied pressure deforms the bonding bumps to form a metal-to-metal bond.

Abstract: A semiconductor technology implemented high-frequency channelized filter includes a dielectric substrate with metal traces disposed on one of two major surfaces of the substrate. An input and output port disposed on the substrate and one of the metal traces carrying a high-frequency signal to be filtered between the input and output port. Other of the metal traces are connected to the one metal trace at intervals along the length of the one metal trace each providing a reactance to the high-frequency signal where the reactance varies with frequency and additional traces of the metal traces serving as a reference ground for the one metal trace and the other metal traces. A silicon enclosure mounted to the substrate with a first planar surface with cavities in the enclosure that extend through the first surface, and internal walls within the silicon enclosure defining the cavities. A layer of conductive metal covers the first planar surface, cavities and the internal walls. The silicon enclosure having substantially continuous areas of metal on the first planar surface about the periphery of the silicon enclosure that engage corresponding areas of the additional traces about the periphery of the substrate. The cavities surround the respective other metal traces with the internal cavity walls engaging the additional traces adjacent the respective other metal traces to individually surround each of the other metal traces with a conductive metal thereby providing electromagnetic field isolation between each of the other metal traces.
