A process for discovering a path from a source node to a destination node through a network by using “collisions” of randomly-propagating “feeler” packets originating from both the source node and the destination node. A discovered path is reported to the source node by the collision-detecting node where it may be stored and updated responsively to reports of new feeler packet collisions. Paths discovered and reported may be analyzed at either the collision-detecting node or the originating node to remove loops. The random collision-detecting path-discovery procedure reduces the operational traffic overhead associated with other exponentially-proliferating discovery methods. The feeler packets are propagated randomly through the network topology, thereby imposing relatively uniform path-discovery traffic effects in the network. Path discoveries arising from feeler-packet collisions always reflect current network topology and traffic conditions. The origination rate of feeler packets may be adjusted responsively to changes in demand, cost or other parameters.

Many speakers, especially small speakers are susceptible to distortion if too much power is applied in certain vulnerable frequency bands. The distortion can be prevented by applying equalization to the audio signal driving the speaker. An equalizer can be configured to suppress the audio signal in the vulnerable frequency bands. The equalizer monitors the power in the vulnerable frequency bands and suppresses those vulnerable frequency bands only when they have sufficient power to distort. In this fashion, undesired audio effects due to the equalization can be avoided.

A backlight device for LCD displays is disclosed herein. The backlight device contains multiple LEDs as light source and a uniforming chamber positioned between the LEDs and the LCD panel.
