Bluetooth in the line of fire? New Scientist reports of a police gun invention that when fired will automatically send its position to fellow officers who can then, presumably, provide backup.
The idea is that when a police officer is holding his gun correctly — both hands on the weapon — he or she can’t easily reach for the radio. So inventor Kevin Sinha of Georgia, “has come up with a simple way around the problem and Motorola, which has made police radios for many years, has pitched in.” The invention involves a Bluetooth transmitter chip controlled by a sensor in the gun which detects when the firing pin is triggered. Whenever a shot is fired the gun sends out a signal to a GPS radio on the wearer’s belt which determines the wearer’s precise position and transmits a pre-recorded message along with the location.
An interesting use of Bluetooth (and GPS). Of course, knowing how hard it is to couple two Bluetooth devices, and their tendency to need “waking up” even if they are paired, I wouldn’t want to rely on it in hairy situations. Like being shot at, for example.
The Wine Spectator Online (via Boingo Wi-Fi Insider) reports that a Sonoma, CA, vineyard is using Wi-Fi to monitor growing conditions at their site:
The system uses 40 wireless units on existing trellising posts around the 30-acre vineyard fitted with sensors that measure microclimate data such as soil and air temperature and moisture content, rainfall and leaf wetness. The data is bounced from sensor to sensor sans wires, forming what is known as a Mobile Ad-hoc Network (MANET), which requires less power and equipment than networks using wires or radio transmitters.
Real-time conditions in the vineyard can then be monitored on a secured Web site. Data can also be poured into a spreadsheet for long-term analysis. The information can help vineyard managers make decisions about when, where and how much to water vines or spray to control mildew.
The system sends alarms via instant messaging software or cellphone. The article quotes Bill Westerman, who works for Calif.-based Accenture Technology Labs which set up the project, as saying that the system could be used in manufacturing, retail and security. “The advantage to wireless is that it allows companies to go places where it was previously too difficult or expensive to run wires,” he said. “It can also be implanted in new products so they can automatically communicate with their manufacturer when there’s a problem.”
