Abstract: A method for manufacturing stringers for aircraft, wherein the stringer comprises two semi-stringers, includes steps of placing tows on a flat surface for forming the semi-stringers independently or at the same time, the placement being made by partially overlapping the tows and orientating the tows on the flat surface according to boundaries of the flat surface, the tows covering the boundaries of the flat surface; and cutting the tows so that a shape of the tows corresponds to the shape of the flat surface defined by boundaries of the flat surface.

Abstract: Systems, devices, and methods of protecting electronic or Internet-connected devices against fraudulent and malicious activities. A Data Collector and Mediator Unit monitors network traffic, and generates datasets of network traffic; each dataset includes network traffic monitored within a time-slot having a particular fixed time-length. A Predictor Unit includes a Features Extractor, to extract features from the datasets; and a Machine Learning (ML) unit, to run the extracted features through a ML model and to classify a particular traffic-portion as being either (I) an anomalous traffic-portion that is associated with fraudulent or malicious activity, or (II) a non-anomalous traffic-portion that is not-associated with fraudulent or malicious activity. The ML unit operates on both (i) anomalies in traffic patterns, and (ii) anomalies of user behavior and/or device behavior.

Abstract: A tube spacing and fastening system for a gas turbine engine includes a plurality of tubular structures, a wear sleeve, a spacer element, and a fastening element. The plurality of tubular structures provides a fluid flow to a component of the gas turbine engine. The wear sleeve is located around each of the plurality of tubular structures. The spacer element receives the plurality of tubular structures. The fastening element extends around the wear sleeves and is configured to secure the plurality of tubular structures to the spacer element. An interference between the fastening element and wear sleeves is configured to allow the fastening element to slide with respect to the wear sleeves and to provide a damping effect under gas turbine engine vibrations and operating conditions. A method of damping vibrations in the plurality of tubular structures includes allowing the fastening element to slide with respect to the wear sleeve.

Abstract: The present invention is related to a method for centering a pouring tube in a pouring tube assembly using a multi-piece centering sleeve by inserting a pouring tube into a holding casting aperture in a holding casting; pouring grout to fill a portion of a gap between the pouring tube and the holding casting; slipping the centering sleeve over the outside of the pouring tube until it is press fit in a portion of the gap between the pouring tube and the holding casting; adjusting the centering sleeve to center-position the pouring tube; grouting the remainder of the gap to fill all voids in the gap; installing a parting ring on top of the holding casting; and installing a holding ring around the holding casting and parting ring.

Abstract: A school bus stop sign assembly for enhancing safety of children entering and exiting a school bus includes a hinging unit that is coupled to an outer wall of a school bus. The hinging unit is actuated into a deployed position and a stored position. A member is coupled to the hinging unit and the member extends outwardly from the school bus when the hinging unit is actuated into the deployed position. Thus, the member extends across a roadway on which the school bus is driving to inhibit a vehicle from passing the school bus thereby enhancing safety for children entering or exiting the school bus. A pair of video cameras is each coupled to the member to capture imagery of the environment around the member.

Abstract: It is proposed a method and system to improve the security of electronic messages exchange between two or more users. The proposed electronic messaging mechanism allows guaranteeing the integrity of a message exchange (i.e., no message has been added, modified, reordered, nor removed from the message exchange), as well as its non-repudiation (i.e., users are univocally associated with the message exchange and cannot deny being authors of the messages they sent), using a local or external blockchain.

Abstract: An optical communication fiber link including a monitoring system connected to an optical fiber transmitting electromagnetic radiation including a communication. The monitoring system includes a detection system detecting a scattering of the electromagnetic radiation from the optical fiber. The monitoring system monitors the scattering for an abnormal change and determines, from the abnormal change, an absence or a presence of a fault in the optical fiber.

Abstract: A system and a method for user authentication and/or authorization, including a passive card to encode a first portion of an authentication or authorization code for a user via capacitive points, and a portable computing device with a capacitive screen to encode a second portion of the code. Each capacitive point is connected to an electronic circuit, being activable by physical contact of the user or with an electrical ground. Once the user has requested access to a specific service or operation, and when at least some of the passive points are activated and the passive card is in contact with the capacitive screen, the device reads the capacitive points, decoding the first portion of the code, and cryptographically signs the decoded portion using the second portion, providing the code, which is used as cryptographic key to grant access to the service or operation.

Abstract: A power unit powers a Long Range (LoRa) gateway at a communications facility. The power unit has one or more enclosures configured to install on a ground level of the communications facility. The one or more enclosures hold batteries and control circuitry. The batteries are configured to supply backup power. The control circuitry is connected to grid power, alternative power, and the backup power and powers the LoRa gateway with power-over-ethernet (PoE). The control circuity is configured to transition from the grid power to the backup power to power the LoRa gateway in response to an outage of the grid power. The control circuity can also transition to the alternative power, such as generator power or solar-generated power, to power the LoRa gateway. Finally, the control circuitry can charge the batteries using the grid power (if available) or using the alternative power (e.g., solar-generated power or other).
