Abstract: A method of operating a three-dimensional (3D) metal object manufacturing apparatus selects operational parameters for operation of the printer to form conductive metal traces on substrates with dimensions within appropriate tolerances and with sufficient conductive material to carry electrical currents without burning up or becoming too hot. The method identifies the material of the substrate and the bulk metal being melted for ejection and uses this identification data to select the operational parameters. Thus, the method can form conductive traces and circuits on a wide range of substrate materials including polymeric substrates, semiconductor materials, oxide layers on semiconductor materials, glass, and other crystalline materials.

Abstract: A lowband radiator has four dipole arms and a central region that is centered at the intersection of the dipole arms. Each of the dipole arms has a sequence of capacitive and inductive structures and a pair of high gain wings that are disposed in the dipole central region. In one embodiment of the lowband radiator, each dipole arm has a gap within the central region that is colinear with the dipole arm. The dipoles provide for improved isolation from nearby midband radiators while providing high gain.

Abstract: Image processing is described. An example method includes generating a feature extraction layer portion of an image classification model based on a deep neural network (DNN) model, and extracting features of a group of images by using the feature extraction layer portion. The method further includes training an output layer portion of the image classification model according to the features of training images in the group of images and classification labels of the training images. The method further includes generating the image classification model by combining the feature extraction layer portion and the output layer portion. Embodiments of the present disclosure implement a lightweight artificial intelligence (AI) solution on a storage system. An expanded storage system can facilitate the generation of AI applications and assist in training an image classification model more quickly, and the obtained image classification model can also produce high accuracy on a small training set.

Abstract: Methods, apparatus, systems, and articles of manufacture to generate reference signature assets from meter signatures are disclosed. Example apparatus disclosed herein include a signature comparator to compare meter signature strings with search signature strings to identify a first fragment match result, which is associated with a sequence position within a first media represented by the search signature strings included in the first fragment match result, and which is also associated with a length of the first media. Disclosed example apparatus also include candidate signature asset generation circuitry to generate a candidate signature asset from a meter signature sequence based on the sequence position and the length of the first media, and store the candidate signature asset in a candidate pool associated with the first media.

Abstract: A wireless communication system wirelessly transfers a network integration request to a distributed ledger over a communication satellite. The network integration request indicates an access node identifier, ledger credentials, and geographic location. The distributed ledger validates the ledger credentials, and in response, translates the access node identifier and the geographic location into an access node configuration. The distributed ledger transfers the access node configuration to the wireless access node over the communication satellite. Based on the access node configuration, the wireless access node wirelessly registers with a wireless communication network, wirelessly exchanges user data between User Equipment (UEs) and the wireless communication network, and hands-over some of the UEs with neighbor access nodes.
