Exemplary embodiments are directed to bidirectional wireless power transfer using magnetic resonance in a coupling mode region between a charging base (CB) and a battery electric vehicle (BEV). For different configurations, the wireless power transfer can occur from the CB to the BEV and from the BEV to the CB.

Disclosed is a signal conductor formed as a metal oxide varistor (MOV), the MOV having a first MOV and a second MOV separated by an insulator. In some embodiments, the disclosed signal conductor may be used in a system communicably coupled to a power transmission distribution network, the system capable of launching transverse electromagnetic waves onto a transmission line, where the electromagnetic waves propagating a data signal conveyed to the system by the MOV.

A modular power distribution system, comprising a host device having first and second compartments, the second compartment being dimensioned to automatically align the client electrical coupler with the host electrical coupler and form a protective barrier while the client electrical coupler is in contact with the host electrical coupler. A modular power distribution system comprising a multi-gang host device and a client assembly, and having a series of independently configurable electrical connections and predetermined electrical connections connecting the multi-gang host device, the client assembly, and a cable(s) to deliver power from the cable the client assembly.

An integrated circuit for digital signal routing. Signal routing is achieved with a multiply-accumulate block, which takes data from one or more data sources and, after any required scaling, generates output data for a data destination. Data from a data source is buffered for an entire period of a data sample clock so that the multiply-accumulate block can retrieve the data at any point in the period, and output data of the multiply-accumulate block is buffered for an entire period of the data sample clock so that the data destination can retrieve the data at any point in the period. The multiply-accumulate block operates on a time division multiplexed basis, so that multiple signal paths can be processed within one period of the sample clock.

In some examples, a control audio management engine is configured to interact with guest audio services in respective guests that have different audio management capabilities. The control audio management engine receives an indication of a start of a first audio in a first guest of the guests, the indication comprising an audio stream. The control audio management engine sends, to a second guest of the guests, control information to affect playback of a second audio that is playing in the second guest.

A signal transceiver circuit, a method of operating a signal transmitting circuit, and a method of setting a delay circuit are provided. The signal transceiver circuit is used to send an output signal and receive an input signal, and includes: a delay circuit for delaying a first clock to generate a second clock; a first digital-to-analog converter (DAC) for converting a first digital signal into the output signal according to the first clock; a second DAC for converting the first digital signal into an echo cancellation signal according to the second clock; an analog front-end circuit for receiving the input signal and the echo cancellation signal and generating an analog signal; and an analog-to-digital converter (ADC) for converting the analog signal into a second digital signal.

Methods and systems are provided for audio devices with enhanced directional operations. In a system that includes one or more audio output components, positioning information associated with at least a part of a user's body may be determined, the positioning information including at least orientation related information. The one or more audio output components may be controlled based on the determined positioning information, with the determined positioning information corresponding to a positional nature of the user within a three-dimensional space around the user, and where the controlling includes providing a three-dimensional audio environment according to the user.

Aspects of the subject disclosure may include a generator that facilitates generation of an electromagnetic wave, a core, and a waveguide that facilitates guiding the electromagnetic wave towards the core to induce a second electromagnetic wave that propagates along the core. The core and/or the waveguide can be configured to reduce radiation loss of the second electromagnetic wave, propagation loss of the second electromagnetic wave, or a combination thereof. Other embodiments are disclosed.

A chair system including a main unit and an untethered chair is provided. The main unit includes a wireless transmitter, a subwoofer, an audio stream receiver and a processor. The untethered chair includes a plurality of speakers, a power source and a wireless receiver for receiving a processed audio stream from the main unit.
