Abstract: An ultrasound-assisting quenching process includes: S1) connect the workpiece with the ultrasonic unit tightly; S2) heat the workpiece to the quenching temperature and then hold for a period of time; S3) start the ultrasonic unit, then the ultrasound energy can be injected into the workpiece directly; and S4) put the workpiece into the coolant quickly to make the workpiece to be quenched. The device for this process mainly includes the ultrasonic unit and a heating unit. This invention inputs the ultrasound energy into the workpiece during the quenching process. Under the action of the ultrasound, the grain size of the workpiece after quenching process will be much smaller compared with the conventional quenching process. Therefore, the ultrasound-assisting quenching process can improve the strength and plasticity of the material, and extend the life of the workpiece.

Abstract: Techniques are disclosed for in-band communication of alarm status information or other information between physical layer devices comprising a working device and a protection device in a network-based communication system. In one aspect, a protection receive signal is monitored in the protection device for the presence of alarm status information. The protection device encodes alarm status information extracted from the protection receive signal, and inserts the encoded alarm status information into one or more designated portions of a protection loop-back signal supplied from the protection device to the working device. The protection loop-back signal is monitored in the working device and the encoded alarm status information therein is decoded and utilized by the working device to initiate a protection switching operation.

Abstract: In one embodiment, the present invention is a framer/mapper/multiplexor (FMM) device that can simultaneously (i) send protection copies of both its working incoming high-speed (e.g., STS-12) signal and incoming low-speed signals to a protection FMM device, and (ii) receive corresponding protection signals from the protection FMM device.

Yet further, four or more FMM devices can be configured so that all FMM devices can communicate with their corresponding protection FMM devices using a single, shared, 4-pin link (e.g., quad-OC-3 mode), and still select between working and protection signals at the switching level (e.g., STS-1).
