Apparatus and method for establishing a stable operating point of a H-bridge with a center shunt switch. The stable operating point lets a circuit connected to the H-bridge outputs work in a more ideal condition. As such, an H-bridge with a stable operating point will yield a higher performance and/or save power. Since common mode is one of the biggest sources of electromagnetic interference, a stable operating point in an H-bridge also suppresses EMI.

Disclosed herein are systems and techniques for audio and lighting control in a bus system. For example, in some embodiments, a bus system may be configured for operation as a light organ and/or to generate sound effects based on accelerometer data.

A transceiver having a shared filter for both transmit and receive modes is disclosed. A transceiver includes a transmitter having an output coupled to a signal node, wherein the transmitter is configured to transmit signals onto the signal node during transceiver operation in a transmit mode. The transceiver also includes a receiver having an input coupled to the signal node, and configured to receive signals from the signal node during operation in the receive mode. The transceiver further includes a first filter coupled to the signal node, wherein the filter is shared by the transmitter and the receiver. The filter is coupled between the transceiver and a first terminal of a transmission line.

The present invention relates to the technical field of underwater communications, and discloses a bridging transmission device for underwater wireless signals, which includes a coaxial cable and two conversion assemblies. The coaxial cable can transmit the weak electric signal. The transmission device transmits and converts wireless signals by means of signal bridging between two or among more independent intelligent terminal devices, converts the electromagnetic wave signal and the weak electric signal to each other through two groups of conversion antennas, and transmits the weak electric signal under water through the coaxial cable, so the purpose of the remote transmission of underwater wireless signals can be achieved. The conversion assembly has no need to be wired to the intelligent terminal device through an interface, so the waterproof performance is good, and the universality is high.
