摘要： A semiconductor apparatus includes an internal clock generation circuit, a receiver, and a sampling circuit. The internal clock generation circuit generates a receiving clock signal and a sampling clock signal based on a reference clock signal, the sampling clock signal having a phase different from the receiving clock signal. The receiver receives an input signal in synchronization with the receiving clock signal and to generate an amplified signal. The sampling circuit samples the amplified signal in synchronization with the sampling clock signal to generate an output signal.

摘要： In accordance with one or more embodiments, a communication device includes a dielectric antenna having a feed point and an aperture. A cable comprising a conductorless core is coupled to the feed point of the dielectric antenna. A transmitter is coupled to the cable and facilitates a transmission of first electromagnetic waves to the feed point of the dielectric antenna. The first electromagnetic waves are guided by the conductorless core and propagate along the conductorless core without requiring an electrical return path, and the first electromagnetic waves generate free-space wireless signals from the aperture of the antenna in accordance with a circularly polarized antenna beam pattern.

摘要： Disclosed is a DC circuit breaker capable of interrupting fault currents flowing in both forward and backward directions. The DC circuit breaker includes: a mechanical switch installed on a DC transmission line and being opened to interrupt a current in the DC transmission line when a fault occurs at one side or remaining side thereof on the DC transmission line; a first bidirectional switching device connected in parallel with the mechanical switch and switching currents flowing in both forward and backward directions; an LC circuit connected in parallel with the mechanical switch and including a capacitor and a reactor connected in series to induce LC resonance; a first unidirectional switching device connected in parallel with the LC circuit and switching a current to induce LC resonance; and a second bidirectional switching device connected in series with the LC circuit and switching currents flowing in both forward and backward directions.

摘要： A method of operation in an Ethernet transceiver is disclosed. The method includes initiating a training mode of operation, and transmitting Infofield frames to a link partner. Each Infofield frame including a payload field to provide data to the link partner. A flow of the transmitted Infofield frames is controlled such that a new Infofield frame is not transmitted before a previous Infofield frame is received by the link partner.

摘要： Systems, methods, and computer-readable medium are provided for managing connections of user devices. For example, two source devices may be configured to maintain a data stream with one another. The data stream may enable the two source devices to identify one or more connections between each other and at least a third device. In response to receiving an event that indicates content to be provided to the third device, the data stream may be used by the source devices to configure their network connections with the third device.

摘要： Various techniques are described to terminate a differential wire pair using combinations of CMCs, transformers, autotransformers, differential mode chokes (DMCs), and AC-coupling capacitors. The techniques improve the AC common mode insertion loss without attenuating the differential data signals, while easing the requirements of the CMC. In one example, an autotransformer, having a first winding, a second winding, and a center tap, is connected across a PHY, where the center tap provides a low impedance to ground for attenuating common mode noise. A CMC is coupled across the autotransformer and a pair of wires carrying differential data, where the CMC greatly attenuates common mode noise. The requirements of the CMC are reduced due to the autotransformer.

摘要： An example implementation involves a playback device receiving digital data representing audio content, the digital data encoded in a first format. The playback device causes one or more speaker drivers to playback the audio content. The playback device decodes a portion of the received digital data to convert the portion of the received digital data from the first format to a second format and transmits, via a network interface to a computing device of an identification system, the decoded portion of the received digital data. The playback device receives, from via the network interface from the identification system, metadata corresponding to the audio content, and in response, causes a control device to display a graphical representation of the received metadata, wherein causing the control device to display the graphical representation comprises sending, via the network interface to the control device, the received metadata to the control device.

摘要： A method for performing simulation includes determining whether a model is available for a channel. A model for the channel is generated using signal attenuation parameters provided by a user in response to determining that the model is unavailable. The model includes crosstalk characteristics from crosstalk parameters provided by the user.

摘要： Methods and systems are provided for audio devices with enhanced directional operations. An audio device may generate an audio output; obtain information relating to a position of a listener and/or a location of at least a part of the listener's body; and configure the audio output and/or outputting of the audio output based on the position of a listener and/or the location of at least the part of the listener's body relative to the audio device. Configuring the audio output and/or the outputting the audio output may include optimizing directionality of outputting of the audio output based on a position of a listener and/or a location of at least part of the listener's body relative to the audio device. The position of the listener and/or the location of at least the part of the listener's body may be determined based on sensory data obtained from one or more sensors.
