...Tagging: Wavetrend, a U.S.-based company, makes electronic tags that constantly transmit data over low-frequency radio waves. The tags can be worn by people or attached to things, allowing computers to track where they are and where they are allowed to go. The company says it is in discussions with the U.S. military, which is interested in tagging both soldiers and equipment, and with airports. Tags could be attached to baggage, making it easier to hunt down suitcases whose owners haven't boarded the plane...
...precise it consists of a single photon. The photon flies at (what else?) the speed of light to a finely calibrated receiver 2 km away, which collects it like a catcher snagging a Randy Johnson fastball. By sending a series of photons polarized at different angles, Hughes can transmit information: each particle represents a single bit--a 1 or a 0, in computer language...
...Ashcroft's antiterror campaign has already irked civil libertarians. Two weeks ago the Attorney General quietly rewrote federal rules to allow feds to monitor communications between inmates and their lawyers. To trigger the eavesdropping, the Attorney General need have only a "reasonable suspicion" that an inmate may try to transmit terrorism instructions through his attorney. Justice Department officials pointed out that the fruits of the eavesdropping would be used only to prevent imminent attacks and that the information could not be used in court--at least not without a judge's approval. But civil libertarians and defense lawyers were furious...
Congressional squabbles have also slowed progress on another key issue: international-flight manifests. Most airlines transmit passenger lists to U.S. Customs as flights take off, so they can be checked against databases at 24 federal agencies, including the FBI and the INS, and compared with terrorist watch lists. But Saudi Air--where most of the Sept. 11 hijackers came from--has resisted. Attempts to require manifests as a condition of landing in the U.S. have stalled on procedural grounds. Congressional backers say they will keep trying...
...cute too. Meet CoWorker, the office robot. About 3 ft. high, this Pentium-powered bot uses sonar sensors to keep her from bumping into walls and people as she rolls along at a languid one mile an hour. A digital camera perched atop her rotating, cranelike neck can wirelessly transmit pictures of remote assembly lines, construction sites or high-security areas straight to the boss. A home version, tentatively planned for the future, might keep an eye on granny--or the nanny...
