Abstract: In some implementations, a system is capable of dynamically adjusting the configuration of an application without requiring an entire application-wide update. For instance, the system can perform a dynamic application to vary the content provided for output on the application, the arrangement of content within a user interface of the application, techniques by which a user interacts with or accesses the content on the user interface, among others. In some instances, the system can process the dynamic updates while the application is running as an active process on a client device, or while the user is presently using the application. In addition, the system can execute the dynamic updates in manner to minimally disrupt user experiences associated with the application.

Abstract: Systems and methods for tagging data strings in electronic documents using a convolutional neural network model. The method includes receiving an electronic document and extracting data strings from the electronic document. The method also includes tokenizing each of the data strings into tokens and determining a first tag corresponding to a first token for a first data string using a convolutional neural network model.

Abstract: A method of making printed circuit board vias using a double drilling and plating method is disclosed. A first hole is drilled in a core, the first hole having a first diameter. The first hole is filled and/or plated with an electrically conductive material. A circuit pattern may be formed on one or two conductive layers of the core. A multilayer structure may then be formed including a plurality of cores that also include pre-drilled and plated via holes, wherein at least some of the pre-drilled and plated via holes are aligned with the first hole. A second hole is then drilled within the first hole and the aligned pre-drilled and plated holes, the second hole having a second diameter where the second diameter is smaller than the first diameter. A conductive material is then plated to an inner surface of the second hole.

Abstract: Cost effective and efficient methods to maximize printed circuit board (PCB) utilization with minimized signal degradation are provided. The methods include electrically isolating a segmented via structure by controlling the formation of a conductive material within a plated via structure by utilizing different diameter drills within a via structure for trimming the conductive material at the via shoulder (i.e., the rim of a drilled two diameter hole boundary). The trimmed portion may be voided in the via structure for allowing electrically isolated plated through-hole (PTH) segments. One or more areas of trimmed rims within the via structure are used to form multiple stair like diameter holes to create one or more voids in the via structure. As a result, the formation of conductive material within the via structure may be limited to those areas necessary for the transmission of electrical signals.
