Gridlogix, Inc., a leading creator of enabling interoperable XML Web Services technology today announced enhanced support for Dust Networks’ SmartMesh™ wireless sensor network. SmartMesh is a wireless mesh sensor network used in remote monitoring and control. The Gridlogix EnNET® XML Web Service application extends the functionality of the SmartMesh system to include robust protocol translation between the wireless mesh network and other automation protocols and systems. EnNET translates the SmartMesh wireless protocol into BACnet/IP, SNMP, and LonWorks® allowing Dust Networks’ wireless sensor network to be seamlessly integrated with existing automation networks.

Robomote and Mobile Sensor Networks

Robomote and Mobile Sensor Networks 04/09/2004 04:01 PM
Since we first reported on Smart Dust back in May of 2001, lots of progress has been made in two directions. The smallest motes are still steadily shrinking towards the size of dust. Meanwhile, the big motes are getting smarter and evolving into COTS Dust and mote-based mobile sensor networks. Robomote is a mote developed by the USC Center for Robotics and Embedded Systems. Robomote is a macro mote designed to act as part of a mobile sensor network made up of hundreds or thousands of identical robots that would monitor the environment. A recently published a working paper (PDF format) from CRES describes the AVR-based Robomote and its potential applications in detail. Many of the design features of the Robomote could be applied to any small, mobile robot.

My latest TheFeature article is about ways to make tiny batteries last for years.

At Cornell University in Ithaca, N.Y., researchers are trying to make a nuclear-powered battery with a very long life span. They've built prototype batteries that use a speck of nickel-63 (a radioactive isotope) to vibrate a tiny cantilever. The cantilever could be made from a piece of piezoelectric material, which could supply power to the sensor. Nickel-63 has a half-life of around 100 years, so it could provide power for several decades. Nukes make people nervous, but there's not enough radioactive material in the prototype to cause a mini-meltdown -- it's comparable to the amount found in a smoke detector. Still, researchers acknowledge that they have a perception problem to overcome.

Broadcom Alleges Atheros Chips Degrade
Adjacent Networks 11/14/2003 08:43 PM
Broadcom says that Atheros's 108 Mbps mode in its Super G featureset found in NetGear and D-Link devices significantly degrades nearby network performance across the entire 2.4 GHz band: Associate Editor Nancy Gohring and I filed this breaking news for PC World's online news site today. The allegations by Broadcom could shake the consumer industry slightly. We wrote this story now because Broadcom plans to demonstrate their findings at Comdex next week, and we felt this was the right time to provide the context we'd be been researching all week for the story. If the methodology Broadcom used to conduct the tests is reproducible -- they claim these tests show that Atheros's products have a large negative impact on 802.11b and 802.11g networks -- then D-Link, NetGear, and Atheros will need to issue firmware upgrades, disable the mode, or recall equipment. Equally problematic: if Broadcom's claims are not reproducible or their testing methods and assumptions are faulty, they've gone a long distance out of their way to make themselves look unreasonable. You might wonder why Nancy and I filed for PC World instead of breaking this news directly at this site. When Broadcom first briefed me on this problem on Monday of this week, I turned to the PC World editor who had recently assembled an exhaustive coverage section on 802.11g access points and their configuration and compatibility. That set of articles showed that many current 802.11g devices still have bugs to be worked out. In discussions with the reviews editor and the online news editor at PC World, we talked about how best this story could be written without being either speculative or sensationalist. Their advice and willingness to act as touchstones in our reporting made it clear that we should work with them on the story. They vetted this through their network experts as well to confirm that the technical details were right. I had and have a lot of trepidation about this story. We don't want to seem naive and give credence to a claim that's scientifically provable and which I've seen the results of but not the process until we know that it's reproducible. But given that this is about to go prime time, as it were, we all felt it was the right point to provide as much background as possible to root Broadcom's claims and Atheros's rebuttal in reality....

ThereminVision Sensor

ThereminVision Sensor 05/01/2004 04:05 PM
Terry Fritz, well known among Tesla coil experimenters, has created a new variant on the e-field sensor for use in mobile robots. He calls his creation ThereminVision. Not satisfied with the sensitivity of the Motorola e-field sensor, Terry came up with a more sensitive, digital version optimized for use as a proximity detector for robots. The ThereminVision sensor can detect capacitance levels 1/10000th the size of the Motorola sensors minimum. While the Motorola sensor was designed to detect a human body in a car seat, for example, the ThereminVision sensor can detect virtually any small object with a density higher than that of styrofoam. It achieves this sensitivity by using a technique similar to that employed in the Theremin. A kit version of the sensor can be purchased online. The documentation includes schematics, PCB layouts, and photos of a prototype robot using the sensors. Want more details on what makes Terry's e-field sensor different from the Motoroal chip? Read on for an in depth explanation Terry offered.

Canesta Equinox 3-D Sensor

Canesta Equinox 3-D Sensor 08/10/2004 01:50 PM
Canesta has announced a new 3-D image sensor that could have applications in machine vision and robotics. What's it do? According to Canesta, the Equinox chip resolves a scene into pixels, as does an ordinary camera chip, but instead of simply providing the brightness of each pixel, Equinox additionally provides the distance from each picture element to the sensor chip. On the downside, the device only provides a 64x64 pixel image and only MS-based, proprietary development software is available at present. Canesta claims it will be a "low-cost" sensor but there's no word yet on a price. At present the sensor is only available as part of a development kit for $7,500. For more technical details, see the developement platform data sheet (PDF format). You can also read more about the sensor in CNET and EE Times articles.

Sound sensor based on human brain
process 04/12/2005 11:50 AM
David Pescovitz: The Office of Naval Research sponsored the development of software based on human brain processes that "recognize, identify, and locate the source of suspicious noises." The software powers the Smart Sensor Enabled Neural Threat Recognition and Identification (SENTRI) system sold by an Illinois company called Safety Dynamics. (More on SENTRI here .) From the Office of Naval Research press release:

The sound identification could be coupled with chemical or optical sensors, so that if exhaust fumes are detected at the same time as a weapons-like "bang," the system would identify a truck backfiring rather than a weapon discharging. The Chicago and Los Angeles County police departments are testing the system to help fight crime in areas that are low on beat officers. Safety Dynamics received a Small Business Innovation Research Phase I award from the Navy in 2004 and is working on adapting its system for a lightweight mobile version that could be hand carried into the field.

Ironically, the press release, issued by the US military, has the headline "Hey, now, what's that sound," a misquoted lyric from a classic anti-war song. Link

Some Apple Powerbooks have a motion sensor inside that allows the computer to detect how it is being moved. This is useful for, eg, emergency harddrive head parking when a sudden fall is detected. Amit Singh, while preparing for a book on OS X internals, has written several programs that use the motion sensor for other purposes. This page mentions those and then goes into great detail about a device driver to use the motion of the computer as a substitute mouse.
