Abstract: An airfoil of an aerodynamic surface including: a control surface having an upper surface and a lower surface, and an actuator configured to elevate or lower the control surface, wherein at least a portion of one of the upper surface and the lower surface of the control surface is auxetic with a negative Poisson ratio, and the other of the upper surface and the lower surface of the control surface includes a material with a higher Poisson ratio.

Abstract: Disclosed is a method of classifying non-visual data. The method may include a stage of receiving each of a plurality of non-visual data and a plurality of classifications. Further, the method may include a stage of transforming the plurality of non-visual data into a plurality of visual images. Additionally, the method may include a stage of generating an image classifier based on the plurality of visual images and the plurality of classifications. Further, the method may include a stage of receiving an un-classified non-visual data. Furthermore, the method may include a stage of transforming the un-classified non-visual data into an un-classified visual image. Additionally, the method may include a stage of assigning a classification to the un-classified non-visual data based on classifying the un-classified visual image using the image classifier.

Abstract: Embodiments of the present disclosure may provide a platform configured to forecast customer churn in a telecommunication network. The platform may be configured to receive customer activity data. The platform may then compute features associated with the customer activity data. These features are then inputted into a machine learning model used for predicting customer churn. Finally, the platform may then provide a report indicating customer churn predictions. The platform may be trained in a training phase prior to entering a prediction phase. The platform may employ an ensemble of statistical machine learning classifiers. An ensemble of classifiers may comprise a set of classifiers whose individual decisions are combined to generate a final decision. An ensemble consistent with embodiments of the present disclosure may be composed by several supervised classification algorithms, including, but not limited to: random forest, neural networks, support vector machines, and logistic regression.

Abstract: An insulation displacement terminal assembly comprises an insulation displacement terminal having a U-shaped insulation displacement portion which has two plate sections that are connected by a bight and insulation displacement slots that extend through the bight and down into the plate sections in aligned pairs of insulation piercing slot portions. A plurality of insulated electric cables are disposed in the insulation piercing slot portions and retained therein to form a sub-assembly. The sub-assembly is assembled into a slide-in insulator housing portion which has slots in its opposed side walls through which the insulated electric cables of the sub-assembly extend and a retention tongue that is cantilevered from a back wall of the housing portion and runs parallel to the slotted side walls to project between the insulated electric cables and the bight of the insulation displacement terminal to retain the electric cables down in the insulation displacement slot portions.

Abstract: A plurality of permanent magnet DC motors are grouped into two banks. One side of each motor in one bank is connected to a first common supply conductor while one side of each motor in the other bank is connected to a second common supply conductor. Independently operable switches are provided for connecting the other sides of respective ones of the motors in the first and second banks to a third common supply conductor. Three additional power switches are provided for reversibly connecting a source of potential across either bank of motors. By proper switch selection one or more motors in either of the banks may be operated in a selected direction of rotation.

Abstract: A noise tolerant time division multiplex system including a transmitter and receiver, each constructed as a monolithic integrated circuit and interconnected by a serial data wire. Data as well as power is supplied to the transmitter from a plurality of parallel connected input switches. The transmitter includes a parallel in/serial out shift register controlled by timing logic and further includes a tri-state driver for generating a three-level serial output signal indicative of the status of the input switches. The data is generated at a high rate to eliminate any deleterious effects of noise on the system. The receiver chip receives a regulated energizing potential from the transmitter chip over two additional wires, generates a timing signal from the three-level signal and loads the data in binary format into a serial in/parallel out shift register.
