  • Earphone jack drive circuit
    Patent number: 8831241
    Abstract: An earphone jack drive circuit applied in an electronic device is provided. The earphone jack drive circuit includes a mute circuit; a micro-controller including a detect pin and a control pin; a delay switch circuit including a resistance, a capacitance, an npn transistor and a first current-limiting resistance. During the plugging in or the unplugging out of the earphone, any momentary logic high of the detect pin charges the capacitance, the capacitance discharges when the detect pin is set to be logic low. For a period, the npn transistor is kept on, the connector of the npn transistor is set to be logic low, the input port of the mute circuit is set to be logic low, thereby the mute circuit is controlled to perform the mute mode during the period to eliminate the popping noises of connection and disconnection.

  • Virtual and logical inter-switch links
    Patent number: 8831013
    Abstract: A Layer 2 network switch is partitionable into a plurality of switch fabrics. The single-chassis switch is partitionable into a plurality of logical switches, each associated with one of the virtual fabrics. The logical switches behave as complete and self-contained switches. A logical switch fabric can span multiple single-chassis switch chassis. Logical switches are connected by inter-switch links that can be either dedicated single-chassis links or logical links. An extended inter-switch link can be used to transport traffic for one or more logical inter-switch links. Physical ports of the chassis are assigned to logical switches and are managed by the logical switch. Legacy switches that are not partitionable into logical switches can serve as transit switches between two logical switches.
