    Abstract: Metal bond abrasive articles and methods of making metal bond abrasive articles via a focused beam are disclosed. In an aspect, a metal bond abrasive article includes a metallic binder material having abrasive particles retained therein, where the abrasive particles have at least one coating disposed thereon. The coating includes a metal, a metal oxide, a metal carbide, a metal nitride, a metalloid, or combinations thereof, and the at least one coating has an average thickness of 0.5 micrometers or greater. The metal bond abrasive article includes a number of layers directly bonded to each other. Metal bond abrasive articles prepared by the method can include abrasive articles having arcuate or tortuous cooling channels, abrasive segments, abrasive wheels, and rotary dental tools. Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying a metal bond abrasive article; and generating, with the manufacturing device by an additive manufacturing process, the metal bond abrasive article based on the digital object. A system is also provided, including a display that displays a 3D model of a metal bond abrasive article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of the metal bond abrasive article.

    Abstract: Fiber network for interrogating fiber-optic sensors in a first Passive Optical Network (PON) and in a second PON, the fiber network comprising a test signal transceiver for emitting query signals and for receiving response signals, a first PON and a second PON. Each PON comprises a light source for generating telecommunication signals and a fiber-optic sensor. Each PON can transmit the telecommunication signals to a plurality of subscribers, and is optically connected to the test signal transceiver such that the query signals can be fed into the respective PON and propagate in the PON to the fiber-optic sensor, and such that the test signal transceiver can receive response signals from the fiber-optic sensor through the PON. The fiber network further comprises a query signal splitter, optically connected to the test signal transceiver and to the PONs such that it can feed a query signal into the PONs simultaneously, and such that it can feed response signals from the PONs into the test signal transceiver.

    Abstract: An assembly for covering at least a portion of a cable, such as an electric cable, comprises an elastomeric tube and a hybrid support core structure. The hybrid core structure includes a central core structure formed from a spirally wound separable ribbon that supports a central portion of the elastomeric tube in a radially expanded state, and first and second solid end core structures that support first and second end portions of the elastomeric tube in a radially expanded state. Each solid end core structure has a film disposed on at least an inner surface thereof having a coefficient of friction less than or equal to 0.05.
