Abstract: Methods, systems, and computer readable media can be operable to facilitate a gathering and transmission of monitoring data from a sensor module to a telemetry control center. One or more sensor modules may be attached or otherwise connected to one or more devices that are included within an HFC infrastructure. Each sensor module may include one or more sensors that capture monitoring signals. The sensor module may interface with a communication link that is associated with the device to which it is connected. The sensor module may process the captured monitoring signals and output the processed signals to a telemetry control center, the processed signals being output over a reverse signal path that is utilized by the device to which the sensor module is connected.

Abstract: A fixture for testing electrical equipment. The fixture may have a tool header shaped to releasably engage the test equipment and a plunger that moves generally linearly between a first position and a second position, the first position engaging the test equipment and the second position releasing the test equipment. In some embodiments the tool is header rotatable relative to the plunger. In some embodiments, the tool header is movable relative to the plunger over at least a range of motion of the plunger.

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 (100) includes a threaded boss (101) defining a central axis (104), a metal panel (102), and a fastener (103) to couple the metal panel to the threaded boss. The fastener includes a threaded shaft (105) terminating at a paddle (106), which can be oblong. The metal panel can define an oblong aperture (112), where the paddle is to pass through the oblong aperture when rotated (115) to a first rotational alignment (113) about the central axis. The metal panel can also include one or more retention contours (116,117) disposed adjacent to the oblong aperture. Each retention contour can include a ramp (118,120) defined by a curved central axis (305) and a retention bridge (119,121) defining a recess (122,123) to receive the oblong paddle when rotated to a second rotational alignment (114) about the central axis.

Abstract: An inductive coil or High Q antenna apparatus, method and computer readable media for a wireless system comprises two or more adjacent conductor traces on a substrate. The two or more adjacent conductor traces are arranged parallel to each other and electrically connected at proximal and distal ends. The two or more adjacent conductor traces are displaced from each other by a preselected fixed distance and are arranged in a single layer on one side of the substrate. Advantageously, the two or more adjacent conductor traces effectively reduce the Effective Series Resistance (ESR) and have the effect of improving the Quality Factor Q of the inductive coil enabling data transmission over large distances.

Abstract: A diplex filter having tunable inductors. Preferably the tunable inductors include pads that may each selectively receive one end of a jumper.

Abstract: Systems, devices, and methods for hybrid anti-clipping in optical links in hybrid fiber-coaxial (HFC) networks are disclosed. A hybrid anti-clipping circuit can be included in both the uplink and downlink paths of the HFC network to avoid driving the laser in the optical link above a clipping threshold. The anti-clipping circuit can compare the average, or RMS, input power level and the power envelope of a RF input signal to a clipping threshold associated with the particular laser module being used. If the average power is above the clipping threshold, then the input signal can be attenuated proportionally to avoid clipping. If peaks in the power envelope are above the clipping threshold, then the bias current of the laser module can be adjusted to avoid clipping. Accordingly, the modes of anti-clipping circuit operation include applying attenuation to the input signal and/or adjusting the laser module bias current.
