Abstract: Techniques are described for maintaining a forwarding information base (FIB) within a packet-forwarding engine (PFE) of a router, and programming a packet-forwarding integrated circuit (IC) with a hardware version of the FIB. Entries of the hardware version identify primary forwarding next hops and backup forwarding next hops for the LSPs, wherein the packet-forwarding IC includes a control logic module and internal selector block configured to produce a value indicating a state of the first physical link. The selector block outputs one of the primary forwarding next hop and the backup forwarding next hop of the entries for forwarding the MPLS packets based on the value in response to the packet-processing engine addressing one of the entries of the FIB for the LSPs. Packets are forwarded with the PFE to the one of the primary forwarding next hop and the backup forwarding next hop output by the selector block.

Abstract: A two level lighting ballast is provided, which includes a self-oscillating inverter circuit and a control circuit. The inverter includes an input; an output to selectively provide current to energize a lamp; a switching circuit operating at a switching frequency; a feedback transformer; and an impedance component. The feedback transformer is connected to the output, and drives the switching circuit based on the lamp current. The impedance component is connected in parallel with the feedback transformer, and is operated by the control circuit. When the control circuit enables the impedance component, the switching circuit operates in a first frequency range, and a first lamp current is provided. When the control circuit disables the impedance component, the switching circuit operates in a second frequency range, and a second lamp current is provided. The first frequency range is lower than the second, and the first lamp current is greater than the second.

Abstract: A multi-strike ballast to ignite an electrodeless lamp is disclosed, and includes an inverter circuit, a protection circuit, and a controller. The inverter circuit, upon activation, sends an ignition pulse to the lamp. The inverter circuit shuts down upon receiving a deactivation signal, and activates upon receiving an activation signal, triggering another ignition pulse. The protection circuit senses a change in a voltage associated with the lamp. The sensed changed may indicate that the lamp has not yet ignited or that the lamp is broken. The controller receives the sensed change in voltage and, in response, sends a deactivation signal to the inverter circuit. The controller waits a predetermined time and then sends an activation signal to the inverter circuit. The controller repeats until a change in voltage associated with the lamp is not sensed, or until a predefined number of repeats occur, providing multiple ignition pulses to the lamp.
