Abstract: A control circuit for use in a ballast configured for powering a first lamp set and a second lamp set. The second lamp set is operated via a controller and a second lamp driver circuit. The controller enables the second lamp driver circuit as a function of a monitored value corresponding to a current through a lamp of the second lamp set. The control circuit includes first and second input terminals for selectively connecting to the power supply. The control circuit reduces the monitored value as a function of a connection state of the first and second input terminals of the control circuit to the power supply. Thus, the control circuit causes the controller to selectively operate the second lamp driver circuit in order to energize the second lamp set in combination with the first lamp set.

Abstract: A network device provides a selector list that includes indices of child nexthops associated with the network device, where each of the child nexthops is associated with a corresponding child link provided in an aggregated bundle of child links. The network device also receives an indication of a failure of a child link in the aggregated bundle of child links, and removes, from the selector list, an index of a child nexthop associated with the failed child link. The network device further receives probabilities associated with the child links of the aggregated bundle of child links. Each of the probabilities indicates a probability of a packet exiting the network device on a child link. The network device also creates a distribution table based on the probabilities associated with the child links, and rearranges values provided in the distribution table.

Abstract: A lamp driver circuit to selectively energize one or more lamps is provided. The inverter circuit has a transformer with primary and secondary windings to provide voltage to the lamps. A filter is connected to the primary winding to receive a primary winding signal representative of the voltage across the primary winding. The primary winding signal has a frequency spectrum and the filter detects a particular characteristic of the frequency spectrum that is indicative of an end of life (EOL) condition of the one or more lamps. A control circuit is connected to the inverter circuit and to the filter. The control circuit is configured to discontinue energizing of the one or more lamps by the inverter circuit when the particular characteristic of the frequency spectrum of the primary winding signal is detected by the filter.

Abstract: Resistive switching memory elements are provided that may contain electroless metal electrodes and metal oxides formed from electroless metal. The resistive switching memory elements may exhibit bistability and may be used in high-density multi-layer memory integrated circuits. Electroless conductive materials such as nickel-based materials may be selectively deposited on a conductor on a silicon wafer or other suitable substrate. The electroless conductive materials can be oxidized to form a metal oxide for a resistive switching memory element. Multiple layers of conductive materials can be deposited each of which has a different oxidation rate. The differential oxidization rates of the conductive layers can be exploited to ensure that metal oxide layers of desired thicknesses are formed during fabrication.

Abstract: In one embodiment, a router may store a “neighbor table” for storing the router's Border Gateway Protocol (BGP) neighbors. Each neighbor corresponds to a virtual routing and forwarding (VRF) instance and associated VRF identifier (ID), and the neighbor table indexes the BGP neighbors according to their respective VRF ID. In response to initiating a BGP update generation for a BGP table having BGP network entries, each entry having an associated VRF ID that indicates to which VRF instance the BGP entry is to be advertised, a single lookup operation for each BGP entry is performed into the neighbor table based on the corresponding VRF ID of each BGP entry to determine a corresponding VRF update group of indexed BGP neighbors to which each BGP entry is to be advertised. Accordingly, a shared BGP update may be generated for each VRF update group for the initiated BGP update generation.

Abstract: A unique real time tuning (RTT) process is employed for obtaining the desired optimum device parameter adjustments. The RTT parameter adjustment process is utilized with IP phone or other device chipsets as desired. In one embodiment, RTT provides a graphical user interface to a digital signal processor (DSP), or the like, on the device chipset allowing for observation, evaluation and control of the device parameters in real time. The real time exchange of the device parameter information between the device and an external workstation, e.g., a personal computer or the like, is provided by a User Datagram Protocol (UDP) that runs on a controller on the device, e.g., an ARM processor or the like. In this example, the unique combination of the RTT, UDP and DSP cooperate advantageously to implement, in accordance with the principles of the invention, the desired observability, and control to designers to tune the device, e.g.

Abstract: A control circuit for use in a ballast configured for powering a first lamp set and a second lamp set. The second lamp set is operated via a controller and a second lamp driver circuit. The controller enables the second lamp driver circuit as a function of a monitored value corresponding to a current through a lamp of the second lamp set. The control circuit includes first and second input terminals for selectively connecting to the power supply. The control circuit reduces the monitored value as a function of a connection state of the first and second input terminals of the control circuit to the power supply. Thus, the control circuit causes the controller to selectively operate the second lamp driver circuit in order to energize the second lamp set in combination with the first lamp set.

Abstract: A ballast for driving one or more lamps includes a controller and a current reduction circuit for accelerating a controller reset. Upon detecting a fault, the controller disables the ballast for a preset period of time, and resets. The controller additionally resets when the ratio of a supplied second value to a supplied first value falls below a threshold value. The current reduction circuit reduces the supplied second value in less than the preset period of time, such that the ratio falls below the threshold value and the controller resets. An emergency lighting system includes the ballast as a primary ballast, a backup ballast, and a primary power source. The controller detects a fault if the primary power source de-energizes and the backup ballast disconnects the one or more lamps from the primary ballast. The current reduction circuit accelerates the reset of the controller when the primary power source de-energizes.

Abstract: A restart circuit for causing an electronic ballast to perform a restart in response to reconnecting any lamp of a multiple lamp configuration of the electronic ballast to the electronic ballast is disclosed. The electronic ballast includes a filament health check circuit for providing a first current through a monitored filament of the lamps to a controller of the ballast. The controller restarts the electronic ballast when a determined ratio of the first current to a reference current indicates that the monitored filament has been disconnected or broken (i.e., the first current substantially decreases) and is subsequently replaced or reconnected to the ballast (i.e., the first current returns to a predetermined level). The ballast further comprises a dv/dt circuit for reducing the first current for a transient time period in response to reconnecting a filament other than the monitored filament to the ballast, causing the controller to restart the ballast.
