AnalogDevices iMEMS Accelerometers

15 years ago, Analog Devices revolutionized automotive airbag systems with its unique iMEMS® (integrated Micro Electro Mechanical System) technology. iMEMS accelerometers were the first products in an array of MEMS inertial sensor solutions to use innovative design techniques to integrate small, robust sensors with advanced signal conditioning circuitry on a single chip. Today, ADI offers the industry's broadest accelerometer portfolio, with products addressing a range of user needs including high performance, low power consumption, integrated functionality, and small size.

Frame relay: Wikipedia

In the context of computer networking, frame relay (also found written as "Frame-relay") consists of an efficient data transmission technique used to send digital information quickly and cheaply in a relay of frames to one or many destinations from one or many end-points. Network providers commonly implement frame relay for voice and data as an encapsulation technique, used between local area networks (LANs) over a wide area network (WAN). Each end-user gets a private line (or leased line) to a frame-relay node. The frame-relay network handles the transmission over a frequently-changing path transparent to all end-users.

GPRS: Wikipedia

General Packet Radio Service (GPRS) is a mobile data service available to users of GSM and IS-136 mobile phones. GPRS data transfer is typically charged per megabyte of transferred data, while data communication via traditional circuit switching is billed per minute of connection time, independent of whether the user has actually transferred data or he has been in an idle state. GPRS can be utilized for services such as WAP access, SMS and MMS, but also for Internet communication services such as email and web access. In the future, it is expected that low cost voice over IP will be made available in cell phones.

GSM: Wikipedia

The Global System for Mobile Communications (GSM: originally from Groupe Spécial Mobile) is the most popular standard for mobile phones in the world. GSM service is used by over 2 billion people across more than 212 countries and territories.[1][2] The ubiquity of the GSM standard makes international roaming very common between mobile phone operators, enabling subscribers to use their phones in many parts of the world. GSM differs significantly from its predecessors in that both signaling and speech channels are Digital call quality, which means that it is considered a second generation (2G) mobile phone system. This fact has also meant that data communication was built into the system from the 3rd Generation Partnership Project (3GPP).

Argos

Argos is a unique worldwide location and data collection system dedicated to studying and protecting the environment. Argos helps the scientific community to better monitor and understand our environment, but also helps industry to comply with environmental protection regulations implemented by various governments. To meet system use requirements, all programs using Argos have to be related in some way or form to environmental protection, awareness or study, or to protecting human life. Applications for which a clear governmental interest prevail are also approved.

UniMotion

This is the home of UniMotion, a library for detecting motion detection using the SMS sensor found in various Apple portables. UniMotion is based on Motion with support for additional hardware coming from here. On top of all this, I've created a basic API and implemented probing so that you don't have to know what machine you're on. While Motion has a BSD license, UniMotion is released under the LGPL. The original author and all contributors have given permission for this license change. The intent is to ensure that fixes and improvements aren't hoarded by closed-source projects and to ensure that closed-source programs utilising UniMotion are able to support the newest hardware models, even without support from the vendor. There is software out there that is SMS-aware but doesn't support my MacBook Pro. If everyone uses UniMotion, that will never happen again.

SeisMac

SeisMac is a Mac OS X application that turns your MacBook or MacBook Pro into a seismograph. It access your laptop's Sudden Motion Sensor in order to display real-time, three-axis acceleration graphs. Version 2.0's enhancements make SeisMac an even more valuable tool for classroom demonstrations of seismic concepts and techniques. The resizable, real-time scrolling display shows an enormous amount of acceleration information. Place your laptop on a table and see the seismic waves from tapping your toe on the floor. Lay your laptop on your chest and see your heartbeat. And of course, if there is a real earthquake, SeisMac will be displaying full seismic information while you drop, cover and hold-on.

Wikipedia: Swarm intelligence (SI) is an artificial intelligence technique based around the study of collective behavior in decentralized, self-organized systems. The expression "swarm intelligence" was introduced by Beni & Wang in 1989, in the context of cellular robotic systems...

Wireless sensor network

Wikipedia: A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations.The development of wireless sensor networks was originally motivated by military applications such as battlefield surveillance. However, wireless sensor networks are now used in many civilian application areas, including environment and habitat monitoring, healthcare applications, home automation, and traffic control...

Crossbow Motes

The Crossbow processor/radio boards, more commonly known as motes, allow multiple sensors distributed over a wide area to wirelessly transmit their data back to a base station attached to a computer. The motes run the operating system TinyOS, which handles power, radio transmission and networking transparent to the user. The network formed is adhoc, meaning the motes figure out how to form the most efficient network by themselves. The network also supports multihopping, allowing a mote out of range of the base station to pass its information from mote to mote until the data reaches the base station. With these tasks in place, you can concentrate on building sensing applications.
