Abstract: A system involves LED strings and programmable current source circuits (CSC). An LED current flows through each LED string. Each LED current is controlled by an associated programmable CSC. In one embodiment, the CSCs form a chain. A first CSC uses a reference current for calibration, and thereafter supplies the reference current to the next CSC. When the next CSC detects the reference current, it uses the reference current for calibration. CSCs are calibrated one by one down the chain. In a second embodiment, each CSC can receive the reference current from a common conductor. If the common conductor is detected to be available, then the CSC uses the reference current for calibration. When the conductor is in use, the other CSCs detect the conductor as unavailable and do not attempt to self-calibrate. The CSCs use the reference current one by one, but in an order that changes over time.

Abstract: In accordance with one embodiment, a method includes creating a first session object by a first traffic processor of a first network element operating in an active mode, the first session object being associated with a communication session between an end user terminal and an information provider. The method further includes sending a state synchronization message associated with the first session object from the first traffic processor. The state synchronization message includes a transport layer address associated with a second traffic processor of a second network element operating in a standby mode. The state synchronization message is adapted to be received by the second traffic processor and cause the second traffic processor to create a second session object, the second session object tracking the communication session between the end user terminal and the information provider.

Abstract: Resolving a Layer 3 address includes maintaining an address resolution table at each slave processor of a number of slave processors. The slave processors have a master processor, and the master processor and the slave processors are associated with a unified address. An address resolution table includes one or more Layer 2-Layer 3 address mappings. An address resolution request requesting a Layer 2 address corresponding to a Layer 3 address is sent from a slave processor. The address resolution request uses the unified address. An address resolution response comprising the Layer 2 address is received at the master processor. The master processor sends the response to the slaves.

Abstract: A single terminal is usable to configure an integrated circuit into one of three states. A circuit within the integrated circuit is coupled to the terminal and determines whether the terminal: 1) is tied low by an external connection, or 2) is tied high by an external connection, or 3) is floating or is substantially floating. If the circuit determines that the terminal is floating or is substantially floating, then the circuit sets an operational characteristic of a portion of the circuit (for example, sets a maximum current with which the circuit charges a battery) to have a value that is a function of a resistance of an external resistor coupled to the terminal. If no external resistor is present, then the terminal is floating and the operational characteristic is set to have a zero value. The terminal and circuit are particularly suited to use in a USB battery charger.

Abstract: A CCFL can exhibit different strike characteristics depending on age and temperature. A CCFL in a direct driven CCFL circuit that is difficult to strike can appear to be malfunctioning using a standard start up operation. A controlled start up allows additional opportunities for a slow striking CCFL to strike. In one embodiment, the CCFL of the direct drive CCFL circuit can be initially driven at a switching frequency substantially different than a resonant frequency. Based on certain conditions, the switching frequency can subsequently be allowed to approach resonant frequency in a controlled manner. If the driving frequency reaches the resonant frequency of the CCFL during a set time period, then the CCFL can enter into steady state operation. At this point, the same conditions can be monitored to identify fault conditions in the direct drive CCFL circuit.
