MM - looks like this technology has a few obstacles to overcome before becoming widespread. So I don't think WLGS and similar companies will need to panic just yet. -------------------------------------------- From the Huntsville Times - 12/22/98 Petroff hopes that Time Domains invention - he often calls it the most significant technology breakthrough since the transistor - will keep attention focused on Huntsville as a high-tech mecca. Though Petroff and industry analysts have projected that Time Domains Ultra-Wide Band radio technology could be worth billions, a few obstacles stand in the way of profit for the company. No. 1 on the obstacle list is the Federal Aviation Administration. Because of the way the technology works - it transmits radio waves in nanosecond bursts across multiple radio frequencies - the FAA has objected to the FCC allowing its widespread use. Certain radio frequencies are restricted for aviation, military and police use only. If a number of Ultra-Wide Band devices are put into use, FAA officials say, it could disrupt air traffic. Petroff said Time Domains device likely poses no threat, because its transmissions are less powerful than those from a cellular telephone. That is Time Domains main argument for waiving, then ultimately changing, the FCC rules so that Ultra-Wide Band devices can make use of now restricted frequencies, Petroff said. Hair dryers, laptop computers and cellular phones already are exempted from the rules, he said, because their weak transmissions on restricted frequencies are ''unintentional." What weve been trying to persuade the FCC, is that intention is not as important as interference," Petroff said. "If it interferes it interferes. If it doesnt, it doesnt." Petroff said that since February, the FCC has taken industry, federal agency and public comments on the request to waive the rule so the device can be tested. A longer battle to change the rule is still pending, he said, and it could be several months until a decision is made. Sen. John McCain, R-Arizona, has sent letters to the FAA and FCC in support of Time Domains request. Time Domain also is fighting for its future profitability on another front. Lawrence Livermore National Laboratories made claims in 1995 on the technology, which Fullerton said he first patented in 1987. The fight over who owns the right to license the technology is still ongoing. At U.S. Rep. Bud Cramers request, the House Science Committees Democratic staff is investigating, because national labs like Lawrence Livermore are not legally supposed to compete with private industry. Until those matters are settled, Petroff and inventor Fullerton and Time Domain Corp. continue to work to perfect the Ultra-Wide Band technology. --------------------------------------- regards, Andretti

Hi MM, Been looking for companies utilizing the UWB technology developed by Time Domain. Found one publicly traded company called Patriot Scientific Corp. OTC BB PTSC. It's currently trading at 37 cents. Found this company mentioned on this website: commsci.usc.edu Keep in mind that I could not find anything on their company web page that says directly that they are using the UWB technology. I have no idea what PTSC is all about but I noticed a couple threads on SI. The one below is the most current. Subject 1954 Still need to do more DD. Phil and I have requested from Time Domain a list of licensees and maybe we can find more publicly traded companies there. Still looking... regards, Andretti
