Abstract: A fiber optic cable terminal proximally terminates a stub cable carrying one or more optical fibers. The stub cable is structurally adapted to be advanced through at least a portion of a conduit by distally pushing a distal end of the stub cable from a location that is proximal to a proximal end of the conduit and without applying any pulling force at any location that is distal to the proximal end of the conduit.

Abstract: A detector (100) for surface-enhanced infrared absorption spectroscopy comprises resonators which are distributed over a surface (S) of a support (1), said surface being intended to receive a sample (101) to be tested. The resonators are able to provoke a spectral reflectance of at least 40% for electromagnetic radiation that is incident on the surface of the support, in the absence of a sample, and when the radiation is at the resonance wavelength value of the resonators. The detector has high sensitivity to small amounts of a target molecule.

Abstract: In examples, an electronic device comprises a component, communication port, and a controller coupled to the component and the communication port. The controller is to store operational data of the component during operation of the electronic device. The controller is to provide the operational data to a peripheral device coupled to the electronic device in response to the electronic device establishing a wired connection to the peripheral device via the communication port, the operational data secured by a security credential of the controller. The controller is to receive a repair command from the peripheral device based on the operational data. The controller is to correct a malfunction of the component based on the repair command.

Abstract: A method for determining a connection status of a device to a cable within a network environment is provided. The method comprises obtaining a signal from a non-data carrying wire of the cable by a detector that is digitally isolated from data transmitted in a data carrying wire of the cable within the network environment, modifying the signal transmitted by the non-data carrying wire to the device and evaluating the modified signal to determine a connection status of the device to the cable.

Abstract: In some examples, a method for generating a low data rate signal for transmission from a first network domain to a second network domain, the second network domain logically separated from the first network domain by a firewall, can include encoding a signal from a first device logically positioned within the first network domain to form a data signal, and transmitting the data signal over an out-of-band communications channel from the first network domain to the second network domain.

Abstract: Systems and methods are described herein for detecting connections between components, such as 3D-printed components, using RFID tags, readers, and/or writers. For example, an RFID reader may read an identification code from an RFID tag that is at least partially 3D-printed as part of a first 3D-printed component to verify the connection to a second 3D-printed component. In various examples, the RFID reader may detect different identification codes depending on whether the first 3D-printed component is correctly connected to the second 3D-printed component, incorrectly connected to the second 3D-printed component, and/or connected to the second 3D-printed component in the past.

Abstract: Apparatuses and methods for scanning a flow of parts or products of many various types and formats. The apparatus comprises a plurality of light sources and a plurality of detectors located around a scanning volume to observe build parts or products in the scanning volume from different observation angles, the light sources each to direct light of separate wavelengths over a respective field of view. Each detector has at least one filter to isolate at the detector light from one of the light sources from light from the other of the light sources. The apparatus also includes a controller to operate a plurality of the light sources, detectors and filters to form measurement groups to scan the observable surface of objects in the scanning volume simultaneously from different observation angles, to obtain scanning data for generating a 3D model.

Abstract: An indexed cable arrangement can be installed in a re-enterable housing. The optical fibers of the cable are indexed between a first; ruggedized multi-fiber connector and a second multi-fiber connector. The second multi-fiber connector may be non-ruggedized and disposed within the housing (e.g., at an adapter) or ruggedized and disposed external of the housing (e.g., terminating a stub cable). One or more drop lines are terminated by respective non-ruggedized, single-fiber connectors disposed within the housing. In certain examples, drop lines may be split into multiple connectorized single-fiber outputs.
