Abstract: Embodiments of a multi-transceiver wireless communication device and methods for adaptive multi-band communication are generally described herein. In some embodiments, the multi-transceiver wireless communication device is configurable for half-duplex operation and for asymmetrical full-duplex operation on two non-interfering channels. In some embodiments, a contention-based channel access procedure may be performed to attempt to gain access to both a primary channel and an auxiliary channel. A primary transceiver and an auxiliary transceiver may be configured for asymmetrical full-duplex operation when access to both the primary channel and the auxiliary channel is granted. One of the transceivers may be configured for half-duplex operation when access to only one of the channels is granted.

Abstract: A system and method is described for simplifying implementation of repeater (e.g., re-driver/re-timer) module implementation in high-data-rate interconnects that carry a relatively low-data-rate clock signal as well as the data stream (e.g., PCIe). At the endpoint, any information critical to the function of the repeater (e.g., the most recent data rate negotiated by a pair of endpoints communicating through the repeater) is embedded in the clock signal by pulse-width modulation as ordered sets. The repeater only needs to read the clock-embedded information rather than decoding the data stream. Thus repeaters for such applications reconstruct the high-rate data-stream while actually decoding only the low-rate clock signal. Because the clock-signal protocol is independent of the data-stream protocol, the repeater's operation is protocol-agnostic with respect to the data-stream.

Abstract: A first state of an interconnect protocol is entered. A particular signal is sent according to the protocol to a device over a link. During the first state, it is detected that a response to the particular signal is received in the first state. It is determined that the device supports a configuration mode outside the protocol based on the received response. The configuration mode is entered based on the response. One or more in-band configuration messages are sent within the configuration mode.

Abstract: A structure and a method for suppressing audio noise of electronic equipment are carried out by utilizing an audio noise suppressing structure to cover a periphery or a surface of the electronic equipment or circuits thereof. The audio noise suppressing structure mainly comprises zirconia and at least one oxide serving as a stabilizer.
