The Sound Of Panic
July 27, 2011: Despite one well publicized failure, the sonic cannon (or LRAD, for Long Range Acoustic Device) is increasingly popular for security conscious merchant ships travelling in the Indian Ocean (between western India and Africa). This vast area has become the hunting grounds for Somali pirates (using seagoing fishing boats or small cargo ships as mother ships.) The pirate vessels have two or more speed boats in tow, and these are turned loose, with half a dozen of more armed pirates each, when a likely target is spotted. Attacking at dusk or dawn, the speedboats can often get close enough, without being spotted, for the pirates to board.

LRAD Conquers The Naval World
October 5, 2011:
The Indian Navy has joined its Western counterparts in equipping its ships, off the Somali coast, with sonic cannon (or LRAD, for Long Range Acoustic Device). LRAD is basically a focused beam of sound. Originally, it was designed to emit a very loud sound. Anyone whose head was touched by this beam, heard a painfully loud sound. Anyone standing next to them heard nothing. But those hit by the beam promptly fled, or fell to the ground in pain. Permanent hearing loss is possible if the beam is kept on a person for several seconds, but given the effect the sound usually has on people (they move, quickly), that is unlikely to happen. LRAD works. And on a speedboat, you have nowhere to run. The LRAD operator targets the guy operating the outboard engine, and anyone else who tries to keep the speedboat headed for the target.

February 21, 2011: As Somali pirates move farther from the coast (using stolen fishing vessels as mother ships), most shipping in the Indian Ocean is at risk of attack. In response, more ships are putting armed guards on board, even though this practice risks running into laws barring firearms on merchant ships entering their ports or territorial waters. Recently, the ICS (International Chamber of Shipping), a trade organization representing 80 percent of all shipping companies, urged its members to put armed guards on ships moving through pirate infested waters. This now includes most of the Indian Ocean between India and Africa. There are problems with this, beyond gun restrictions. Some countries forbid ships flying their flag from carrying armed guards.
None of this has stopped several private security companies from offering armed guards for ships. The security companies operate from countries that allow them (sometimes after payment of bribes) to have military grade weapons. The security teams sometimes travel unarmed to a port where they can pick up their weapons, and board the ship they are guarding. That works because some shipping companies are carrying rifles and machine-guns on board, but keeping them hidden from port and cargo inspectors. Large merchant ships have lots of places to hide things like a dozen rifles and pistols and a few thousands rounds of ammo. Other security companies will send out a small ship with the armed men on board, and transfer them to the merchant ship in international waters. In short, no one wants to talk openly about how this security business operates. But there's a growing demand, and no shortage of security companies willing to fill the need. This makes lawyers for shipping companies nervous, because of the risk of innocent fishermen getting shot if they approach a guarded ship way that makes the merchant crew nervous. One thing leads to another and someone who isn't a pirate gets shot. Lawsuits follow, and the shipping company has another pirate-related problem. But the shipping companies have reached the point where they would rather handle these lawsuits than more ransom negotiations with pirates.

Looks like promising technology.
"Quantum-dots displays would consume a fifth to a tenth of the power of LCDs, says Samsung research Tae Ho Kim. They promise to be brighter and longer-lasting than OLEDs. What's more, they could be manufactured for less than half of what it costs to make LCD or OLED screens. "

Dude - I TOLD you to sell more than once! Imagine if you did - you would be worry-free right now, and more importantly, we wouldn't have to read any more of your hand-wringing posts.
