Media matrix

Joshua Lifton, Jay Lee
2001 CHI '01 extended abstracts on Human factors in computer systems - CHI '01  
We introduce Media Matrix, a system applying distributed, embedded computing techniques to the creation and maintenance of a queriable database of physical objects such as compact discs, video cassettes  ...  Rather than powering each tag with its own battery, each item in the collection receives power via conductive strips from the shelf itself, which in turn is plugged into a power outlet.  ...  We plan to explore other distributed embedded computing projects using this same philosophy and technology.

Ching Law, Kayi Lee, Kai-Yeung Siu
2000 Proceedings of the 4th international workshop on Discrete algorithms and methods for mobile computing and communications - DIALM '00  
TAG IDENTIFICATION A tag identification system consists of one reader and n tags. The reader is a powerful entity with abundant memory and computation power.  ...  But this would be unnecessary if we assume that the tag IDs are uniformly distributed.  ...

Extended abstract: The butterfly PUF protecting IP on every FPGA

Sandeep S. Kumar, Jorge Guajardo, Roel Maes, Geert-Jan Schrijen, Pim Tuyls
2008 2008 IEEE International Workshop on Hardware-Oriented Security and Trust  
PUFs are a unique class of physical systems that extract secrets from complex physical characteristics of the integrated circuits which along with the properties of unclonability provide a highly secure  ...  Only tampersensing circuitry with continuous battery power can solve this problem with the associated higher price.  ...  A similar idea to SRAM-based Intrinsic-PUFs is presented in [11] but the focus is on ultra-low power micro-controllers.  ...

When a network is complete the children physically manipulate the PegBlocks and observe how the kinetic energy they put into the system is distributed through out rest of the network.  ...  Through this kind of physically interactive play the children begin to develop a more intuitive understanding of a number of abstract physics principles. Figure 1.  ...  Many asked if the blocks used batteries and were often surprised to learn that the toy used only the energy that the children put into the system.  ...

Making Waves — Towards a New Era of Seismic Recording Equipment

Andy Bull, C.J. Criss
2016 ASEG Extended Abstracts  
RECORDING SYSTEMS In the early 1990's when 3D seismic was picking up, distributed cable systems could field 2,000-4,000 channels live.  ...  System components have grown lighter, are less power hungry, more reliable and most importantly, cheaper.  ...

Interfacing to the foot

Joseph A. Paradiso, Kai Yuh Hsiao, Ari Benbasat
2000 CHI '00 extended abstracts on Human factors in computer systems - CHI '00  
We describe a system that we have developed to capture detailed, multimodal gesture expressed at the foot.  ...  This system, having evolved over 3 years, has been used for real-time expressive performance by a diverse set of artists, including gymnasts, jugglers, and dancers.  ...  The truly wireless nature of this package was a real win; dancers had only to lace up the shoes, and flip the power switch to use the system.  ...
