Abstract: A method and apparatus for cancelling self-interference in a cable network implementing full duplex (FDX). A processor in a cable modem may obtain a frequency response of an echo channel for at least one sub-channel in an FDX band and calculate filter coefficients based on the frequency response, and an interference canceller cancels the self-interference in the downstream signal. The interference canceller includes filters in a digital domain to generate an interference cancellation signal from a reference signal. In another example, the processor may obtain frequency responses of an echo channel for all sub-channels in a FDX band, combine the frequency responses for the FDX band, and generate a channel impulse response for the FDX band from the combined frequency response. The interference canceller may then cancel the self-interference in the downstream signal in an analog domain based on the channel impulse response.

Abstract: The use of traffic flag symbols allows a large number of CPEs to transmit traffic notifications to a network controller. In some such embodiments, hundreds of CPEs simultaneously transmit traffic flags on different subcarriers of a channel. For example, in a MoCA2 based access network, up to 480 CPEs can transmit flags in only 5 ?s in the 100 MHz-wide channel.

Abstract: Disclosed herein are systems and methods for collecting a plurality of medical images. A method includes displaying a list that includes an indication corresponding to each image of a plurality of medical images of a workflow, wherein the indications are listed based on a sequence defined by the workflow. The method includes receiving a selection by a user indicating a specific image to be acquired from the plurality of medical images. The specific image is selected in an order different than defined in the sequence based on a position of an imaging target allowing for capture of the specific image. The method includes acquiring the specific image and displaying an updated list to omit an indication corresponding to the acquired specific image of the plurality of medical images.

Abstract: A method, system and computer program for transmitting at least two payloads in a downstream traffic phase of a time-division duplex (TDD) cycle with a single preamble from a headend followed by concatenated payloads without intervening preambles, whereby the payloads are ranked by increasing modulation profiles. The preamble, and concatenated and ordered set of payloads are then transmitted to two or more predetermined customer premise equipments (CPEs).

Abstract: Arc flash mitigation devices are employed to protect personnel during maintenance of photovoltaic inverters. During normal operation, an alternating current (AC) output of a photovoltaic inverter is coupled to a low voltage winding of a step up transformer through a bus-bar (e.g., an electrically conductive interconnect), which has higher current rating than a fuse. During maintenance, the bus-bar is replaced with the fuse. The fuse may be employed in conjunction with a switch. The switch may be a disconnect switch that places the bus-bar in parallel with the fuse during normal operation, and decouples the bus-bar from the fuse during maintenance. The switch may also be a transfer switch that places either the bus-bar or the fuse in series with the AC output of the photovoltaic inverter and the low voltage winding of the step up transformer.
