Wireless remote data
Technologies and sample systems that gather sensor data across distances, usually via radio links. This includes general telemetry and SCADA (supervisory control and data acquisition), especially for gathering data about wildlife, natural resources, and distributed energy systems.

Solar SeV Finetex Shell: Updated geek jacket, now with solar charger:  "The Solar SCOTTEVEST (SeV) combines the benefits of our signature jacket and removable solar panels. The solar panels enable you to recharge most USB compatible devices on the go, either while wearing the jacket or with the panels removed. When attached, the solar panels compliment the jacketís design. The solar panels charge a small battery - about the size of a deck of cards. The battery powers your device almost immediately after the solar panels are exposed to sunlight. Once the battery is fully charged, the panels can be removed and your portable electronic device can tap into the stored power.   Typical charge times in direct sunlight range from 2-3 hours, but direct sunlight is not required."  Geek cargo pants also available, teflon coated (but no solar panel...).  10:55:10 PM  permalink

AnywhereUSB - USB Over IP: "AnywhereUSB [can] connect USB devices anywhere on a wired or wireless LAN, while eliminating the need for locally-attached host PCs.  AnywhereUSB/5 provides five USB ports, which deliver the same Plug and Play user experience as onboard USB ports. Software drivers are loaded onto a host PC or server, enabling remote devices to communicate with the host, without changing existing application software. Peripheral devices can be centrally managed and monitored from a remote server or PC via an IP address."  $300 list, $250 through resellers, $200 under advertised developer demo program.  11:40:43 AM  permalink  

Watchport USB Sensors: "The Watchport Series is the first complete line of Plug and Play USB devices for 24/7 environmental monitoring. Choose from sensors for proximity, distance, acceleration/tilt, humidity/temperature, water and temperature. The Watchport Series also includes the Watchport/V USB camera. .. Watchport Manager application software provides centralized device status and historical data logging, and allows the easy integration of multiple Watchport devices without additional software development. The customizable software can send email, beeper or phone alerts when undesirable conditions are detected.."  Devices are small and USB-powered, $200 list, $150-190 through resellers, $130 under advertised developer demo program.  11:36:36 AM  permalink

Intel's mesh: 802.11s: "Intel has unveiled its first proposals for 802.11s, a new mesh wireless networking standard.. W. Steven Conner, wireless network architect at Intel and technical editor of the IEEE's 802.11s task group, told engineers at the Intel Developer Forum in San Francisco .. Although mesh networks are already in use for very large deployments in cities such as Taipei, and in some industry sectors, none of the systems interoperate or are suitable for domestic or office environments, Conner claimed. The 802.11s group, which met for the first time in July 2004, has just issued its first call for proposals, and Intel is keen for the new standard to cover domestic and small business environments.

Intel's proposals build on top of existing standards, such as 802.11a/b/g wireless transmission protocols and 802.11i security, and is compatible with them. It adds extra functions to allow wireless nodes to discover each other, authenticate and establish connections, and to work out the most efficient route for a particular task. This includes the concept of quality of service..

The company is also introducing the idea of Mesh Portals -- devices that know how to connect complete mesh networks to other, potentially non-mesh systems such as classic 802.11 networks, new standards such as 802.11n, broadband access points or different wireless technologies such as Ultrawideband and mobile data sources.

Although some recent wireless standardisation efforts have had problems due to entrenched opposing views, Intel thinks there is little risk of this with 802.11s.  The standardisation process is expected to produce a firm proposal towards the end of 2006 or the beginning of 2007, with ratification following a year later. .. Intel is hoping to promote the idea of a core set of standards that work with small meshes of up to around 25 or so reasonably static nodes in close proximity, but in the context of an extensible framework that allows many different mesh models to be implemented. Intel says this should mean anyone with different ideas will be free to implement them, but always in a way that interoperates cleanly with the core protocols.  By limiting the initial core functions, the company says, the additional amount of processing required in the network nodes will be easily managed by the existing class of network adaptors and consumer electronic devices, and as no changes need to be made to existing hardware 802.11s-compatible equipment should reach the market quickly.

Powerline connectivity: "Three Japanese consumer electronics giants have created a new technology to transport Internet and media signals around the home via the electricity network. .. Sony, Mitsubishi and Matsushita-owned Panasonic have set up the SECA powerline alliance.   They have developed a system to transfer 170 Megabits per second of data through the power lines of a home, Panasonic researcher Ingo Chmielewski told journalists at the electronics trade fair CeBIT"  1:06:48 AM  permalink

Radio Time: "TiVo for radio? You bet! Just like TiVo, you can listen, pause, fast forward, or move radio as MP3 files with RadioTime software. Listen to your favorite programs --anytime, anywhere. Record one airing or every broadcast of your favorite programs."  Wonder if it has made peace with the RIAA?  12:49:41 PM  permalink  

frontline: high stakes in cyberspace: Paul Saffo in 1995 on PBS:  Fun to read the old stuff.  Paul Saffo is remarkably on-target, 10 years later.  This article mentions "macro-myopia: A pattern where our hopes and our expectations or our fears about the threatened impact of some new technology causes us to overestimate its short term impacts and reality always fails to meet those inflated expectations. And as a result our disappointment then leads us to turn around and underestimate the long term implications and I can guarantee you this time will be no different. The short term impact of this stuff will be less than the hype would suggest but the long term implications will be vastly larger than we can possibly imagine today."  I've since encoutered Gartner's Hype Cycle, which they say they started to use also in 1995, with a graphic version of this insight. 

I found this when looking for a reference to an aphorism that I think comes from Saffo.   The aphorism:  Over two years, things change much less than we think they will; but over ten years, they change more than we imagine. 

It makes me wonder about the timeframe in between, say 5 to 7 years in the future, when major impacts will be felt from things we know are changing now, despite hype (digital sensors and surveillance) and disillusion (wind and solar power).
