Further, the network device transmits the first broadcast signaling in the second time duration. In this way, the interruptions caused by the long-time period reserved for the broadcast signaling transmission may be reduced.

Abstract: A switched-mode power supply in a set of parallel-connected switched-mode power supplies is operated to (1) monitor both output current and operating temperature, and (2) auto-tune an output voltage using two-dimensional control that employs a two-dimensional function of the output current and the operating temperature. The two-dimensional function is a sharing function whose use in each of the supplies effects a coordinated sharing of both load current and operating temperature across the set of supplies. Temperature sharing includes monitoring and controlling distribution of operating temperatures across the set of supplies to reduce undesirable temperature imbalance that can cause excessive thermal stress and reduce reliability.

Abstract: A power converter includes a power transformer, primary-side circuitry connected between a power source and a primary coil, and secondary-side circuitry connected between secondary coil(s) and a load to generate an output voltage and load current for a load. The secondary-side circuitry includes (i) an output inductor, (ii) one or more power transistors, and (iii) control circuitry generating switching signals to operate the power transistors as synchronous rectifiers. The control circuitry (a) senses an inductor current in the output inductor, and (b) selectively disables the switching signals to the power transistors when the inductor current is less than a threshold current value in a range between a minimally negative value and a minimally positive value, the minimally negative value just preventing diode rectification mode of operation of the power transistors, the minimally positive value just preventing negative inductor current in the output inductor.

Abstract: A method and system use an alternative sensor signal received from a sensor other than an air conduction microphone to estimate a clean speech value. The estimation uses either the alternative sensor signal alone, or in conjunction with the air conduction microphone signal. The clean speech value is estimated without using a model trained from noisy training data collected from an air conduction microphone. Under one embodiment, correction vectors are added to a vector formed from the alternative sensor signal in order to form a filter, which is applied to the air conductive microphone signal to produce the clean speech estimate. In other embodiments, the pitch of a speech signal is determined from the alternative sensor signal and is used to decompose an air conduction microphone signal. The decomposed signal is then used to determine a clean signal estimate.
