Abstract: Determining a bit rate at which to deliver a packet stream over a network link. An origin device transmits over the network link unsolicited data packets to a destination device while contemporaneously transmitting over the network link a first packet stream encoded at an initial bit rate to the destination device. The origin device may be, but need not be, a content delivery network (CDN) edge node and the destination device may be, but need not be, a cable modem (CM). The origin device determines whether the network link supports delivering a second packet stream in lieu of the first packet stream encoded at a higher bit rate based, at least in part, on an amount of retransmission requests the origin device receives for packets in the first packet stream from the destination device.

Abstract: A method for additively manufacturing a component includes receiving, via an additive manufacturing system, a geometry of the component and melting and fusing, via an energy beam of the additive manufacturing system, material layer by layer atop a build platform according to the geometry so as to build up a plurality of layers that form the component. The method also includes determining a surface area change from one of the plurality of layers to the next based on the geometry. Further, the method includes temporarily discontinuing melting and fusing of the material by the energy beam between building of one or more of the plurality of layers so as to provide a delay after building one or more of the plurality of layers when the surface area change is above a predetermined threshold. As such, the delay allows for one or more previously built layers to at least partially cool so as to eliminate and/or reduce build failures from occurring in the final component.

Abstract: A tube includes a center tube comprising a steel material, a fluid flowing through the center tube; and at least one disk disposed around the center tube, the disk including a thermally conductive material and exposed to an external heat source. The disk conducts heat from the external heat source into the center tube. The center tube transfers the heat from the external heat source into the fluid. The thermal conductivity of the at least one disk is higher than the thermal conductivity of the center tube.

Abstract: A diagnostic system for monitoring a status of a CT system includes at least one radiation detector configured to monitor a CT component and generate signals representing measurement data associated with the CT component. The system also includes a diagnostic computer device in communication with the detector. The device is configured to receive an electrical signal from the detector and identify a first frequency in the electrical signal. The device is also configured to compare the first frequency in the electrical signal to a first reference frequency stored in memory. The first reference frequency is at least partially indicative of a first mechanical status of the CT component. The device is further configured to determine that the first frequency in the electrical signal is substantially similar to the first reference frequency and, in response, determine that the CT system has the first mechanical status.
