Abstract: A detachable handle assembly includes a handle configured to removably engage a portion of the cookware, and a locking assembly carried by the handle. The locking assembly includes a push button operably connected to a locking member. The locking assembly is configured to selectively engage the portion of the cookware in response to actuation of the push button.

Abstract: An audio device comprises a processor, an audio processing module, a high frequency noise generating circuit, a first switch control circuit, a second switch control circuit, a low pass filter circuit and an adder circuit. The audio device generates a watermark data, an original audio signal and a high frequency noise signal. The high frequency noise signal pass through a first switch control circuit and a second switch control circuit according to watermark data. A low pass filter circuit filters the high frequency noise signal received from the first switch control circuit to form a first add data. An adder circuit receives the first add data from the low pass filter circuit, receives the high frequency noise signal from the second switch control circuit as a second add data, and adds the first add data and the second add data to the original audio signal.

Abstract: An audio device includes a processor, a storage unit, an audio processing module, a silence detection circuit, a condition determining circuit, a direct current (DC) level bias circuit and an appending circuit. The audio device generates identification data, control signals, and original audio signals. The silence detection circuit detects silence segments of the original audio signals, and generates driving signals if the silence segments are detected. Then the condition determining circuit determines if the identification data needs to be appended into the silence segments according to the driving signals and the control signals, and outputs the identification data in DC signal form if the identification data needs to be appended into the silence segments. After DC voltage level of the identification data in DC signal form is biased, the appending circuit appends the biased identification data into the silence segments of the original audio signals.

Abstract: A method and system for managing admission to a network considers the packet delay of the network in making an admission decision. The packet delay of the network is periodically probed. To avoid disturbing or impairing the traffic of the network, a sequence of probing packets is sent to the network at an irregular interval. Responses to the probing packets are analyzed to obtain delay information of the network. If the delay information is insufficient to make an admission decision, then the packet loss rate of the network is measured and considered.
