Abstract: A system, apparatus, and method are directed to managing multicast routing using a network cluster. A cluster master actively participates in multicast control protocol communications with the cluster neighbors, while non-master member nodes, do not participate in the protocols' operation outside of the cluster. However, each cluster member maintains virtually the same protocol state, such that should the master become unavailable, another cluster member may assume the master role with minimum delay. New members to the cluster are synchronized by receiving initial protocol state information from the master. After the initial protocol state synchronization, cluster members actively monitor the network to acquire new protocol state information. In addition, cluster members exchange protocol state information between themselves that may not be obtainable off the network. Filtering of multicast data packets is performed by each cluster member, to load balance multicast data traffic across the cluster members.

Abstract: A docking station comprises control logic adapted to mate with a portable electronics device to provide the portable electronics device with access to a network. The control logic is able to cause a user-selected activity to be performed by the docking station while a portable electronics device is not mated with the docking station. In another embodiment, a system comprises a docking station to which a portable electronics device is adapted to dock. The docking station contains a central processing unit (“CPU”), an operational device and a remote control interface. The docking station is configured so that regardless of whether the portable electronics device is docked to the docking station, the operational device can be controlled via signals received by the remote control interface from a remote control.

Each of the two output nodes is connected to the control node of a respective one of the current sources, each current source being connected to decrease the current it supplies to the driving node if the potential of its respective output of the converter moves towards the potential of the first power supply.

Abstract: An apparatus, method, and system are directed to maximizing network connectivity after a network failure in a network clustering system. A cluster master in a cluster is configured to manage membership to the cluster based, in part, on a connectivity of the members to adjacent networks. A network device sends information about its connectivity to the cluster master. The cluster master compares the received information to determine whether the network device has different connectivity than the cluster. If the network device has different connectivity, the cluster master may deny cluster membership to the network device. By rejecting network devices with different connectivity, the invention ensures that data received by the cluster may be delivered with substantially equal reliability by virtually any of the cluster members. Thus, even the cluster master may be rejected from membership to the cluster.

Abstract: Methods and systems are directed to managing a protocol network failure in a network clustering system. A cluster master and each client member in the cluster are configured to determine a primary protocol network, a secondary protocol network, and the like, for exchanging a cluster protocol message. Each client member in the cluster determines its ‘active protocol network’ from at least the primary protocol network, and the secondary protocol network when it joins the cluster. Each client member tests its connectivity to the cluster master through the primary protocol network. If a client member detects a failure on the primary protocol network, it dynamically fails over to the secondary protocol network, or the like, without leaving the cluster. If connectivity to the primary protocol network is restored, the client member dynamically resumes the protocol message exchange on the primary protocol network without leaving the cluster.

Abstract: Shaped electrodes for micro-electro-mechanical-system (MEMS) devices to improve actuator performance and methods for fabricating the same are disclosed. The shaped electrodes utilize its three-dimensional geometry to shape an electric field for electrostatic actuation for MEMS devices. For example, the height, width, length, sidewall slope, and layout of the shaped electrodes can be used to provide an optimum electric field in moving a MEMS mirror device. The shaped electrodes can provide electrostatic actuation at a low operating voltage and provide an optimum electric field for maximum tilt or angular range of motion for a MEMS mirror device. The shaped electrodes can be fabricated simply by using a pillar wafer and an electrode wafer. The pillar wafer can be used to form pillars as electrodes, or, alternatively, as barriers. A single substrate can also be used to form pillars and electrodes.
