  • Patent number: 9100329
    Abstract: A device receives traffic; identifies an address associated with the traffic; determines whether the address is associated with an aggregate interface, the aggregate interface being associated with a first port and a second port. The first port corresponds to a first node in a first state, that indicates that the first node is available to forward the traffic, and the second port corresponds to a second node in a second state, that indicates that that the second node is not available to forward the traffic. The device transmits the traffic to the first node via the first port and to the second node, via the second port, when the address is associated with the aggregate interface. Transmitting the traffic enables the second node to forward the traffic when the first node changes from the first state to the second state.

  • Publication number: 20150179889
    Abstract: An electrode structure for effectively improving the stability of a semiconductor LED includes a reflecting layer capable of current spreading. In such an electrode structure, the current injects from the side surface of the reflecting layer to form a certain potential gradient over the contact surface between the electrode and the LED contact surface, thereby inhibiting the metal ion of the reflecting layer from migration due to electric field during usage, thereby improving device stability. In addition, the electrode portion for current injection can include a high-reflectivity material yet not vulnerable to ion migration, thereby increasing the entire reflecting area and improving luminous efficiency.

  • Patent number: 8922711
    Abstract: The present invention provides a method and apparatus for de-interlacing video data by using a horizontal motion vector of a horizontal motion between fields. The horizontal motion regarding a target pixel of a frame is compensated if the horizontal motion vector is found to be substantially not null according to the pixels residing in the fields determined by the horizontal motion vector. This results in an upgraded quality of image after the de-interlacing process.

  • Patent number: 8879734
    Abstract: A light-weight resilient mechanism is used to synchronize server secure keying data with member devices in a highly-scalable distributed group virtual private network (VPN). A server device generates an initial secure keying data set, for the VPN, that includes a first version identifier, and sends, to member devices and via point-to-point messages, the secure keying data set. The server device sends, to the member devices, heartbeat push messages including the first version identifier. The server device generates an updated secure keying data set with a second version identifier and sends, to the member devices, a key push message that includes the updated data set. The server device sends, to the member devices, heartbeat push messages including the second version identifier. Member devices may use the first and second version identifiers to confirm that secure keying data sets are current and quickly identify if updates are missed.
