The hardware and software costs of telerehabilitation systems are summarized. Several hardware and software examples are given in order to look at what has been done, and what can be done in the future. At present only a single low-cost telerehabilitation system (developed at the University of California at Irvine) has been identified. The author does not claim this to be a comprehensive review...

Automating water projects makes economic sense in the western United States. But is it justified in other parts of the world? The authors feel strongly that it is. This paper discusses the experiences of the U.S. Bureau of Reclamation and others in developing, installing, and evaluating low-cost automation systems in the western United States. It also briefly discusses similar low-cost automati...

Introduction One critical area of the Molonglo system is the beamformer. The resistive array is custom made and some spares are unavailable for the computer that collects the data. It would be difficult to recover from a failure in either of these components. The use of this beamformer also results in data (beams) that cannot be processed by standard methods in imaging packages such as AIPS++ o...

A new approach to intrusion detection is needed to solve the problems of larger and faster networks and the constraints on system administrator’s time to manage security systems. Current network intrusion detection systems lack solutions to these two problems being complex in design and generally incurring larger costs in terms of operation and maintenance. We propose a new technique to solve t...

The need for low-cost health monitoring is increasing with the continuous increase of the elderly population. In this context, unobtrusive audiovisual monitoring methods can be of great importance. More particularly, the diameter of the pupil is a valuable source of information, since, apart from pathological cases, it can reveal the emotional state, the fatigue and the ageing. To allow for uno...

This report describes the development of a low cost, digital Micro Electro Mechanical System (MEMS) vibration meter that reports an approximation to the RMS acceleration of the vibration to which the vibration meter is subjected. The major mechanical element of this vibration meter is a cantilever beam, which is on the order of 500 µm in length, with a piezoresistor deposited at its base. Vibra...

This paper presents our work on building low-cost music controllers intended for educational and creative use. The main idea was to build an electronic music controller, including sensors and a sensor interface, on a “10 euro” budget. We have experimented with turning commercially available USB game controllers into generic sensor interfaces, and making sensors from cheap conductive materials s...

In H.264, the context-based adaptive variable length coding (CAVLC) is used for lossless compression. Direct table-lookup implementation requires higher cost because it employs a larger memory to produce the encoded results. In this letter, we present a more efficient technique for CAVLC implementation. Compared with those previous CAVLC chips, our design requires the lowest hardware cost.
