A low-cost mobile pointing and drawing device
Proceedings of the international workshop on Educational multimedia and multimedia education, 2007This paper introduces a system that enables a presenter to work directly on the projected screen without interrupting the presentation flow by mouse or keyboard use. One uses his fingers as a natural pointing device. The system consists basically of an LED and a webcam as well as a small software system that runs on the presenter's notebook. The camera

A Low Cost Device for the Compensation of Voltage Transformers
2008 IEEE Instrumentation and Measurement Technology Conference, 2008In the paper a low cost method for the compensation of Voltage Transformers (VTs) is proposed. The compensation technique is based on a proper circuit connected to the secondary terminals that, by sensing the VT primary current, generates a voltage that compensates the primary voltage drops.

Computer, 1976
Session II of the 1975 Lake Arrowhead Workshop on "Advances in Storage for Minis and Micros" was devoted to low-cost tape devices. This article presents a summary of the discussions in that session. No attempt is made to present an all-inclusive coverage of low-cost tape devices, nor necessarily to present a balanced picture, but rather to present the ...

Secure Web Services for Low-Cost Devices
Eighth IEEE International Symposium on Object-Oriented Real-Time Distributed Computing (ISORC'05), 2005This paper describes how to use XML Web services and public key cryptography on small devices in consumer settings to achieve a high level of interoperation and security. This is done while maintaining the strict performance requirements that are expected from low-cost devices operating with limited energy and other resources.

A low cost searching device for an ATM adapter
Proceedings of Sixth International Conference on Computer Communications and Networks, 2002A key function of an ATM adapter is its ability to sort the incoming traffic from the VPi/VCi field of the cell headers. This has to be done at media speed and requires a hardware assist to keep up with the high speed lines over which ATM cells are transported. Although the device of choice to perform a search is a content addressable memory (CAM) such

Low-Cost Device for Constructing Sorption Isotherms
Drying Technology, 2006Water activity is the main criterion for characterizing the storage and drying behavior of biological products. As current standardized devices are expensive, a cheaper apparatus was designed and built. After preliminary tests, functional specifications were determined.

A global enhancement pipeline for low-cost imaging devices
IEEE Transactions on Consumer Electronics, 2003The paper describes a suitable algorithms pipelineable to enhance the picture quality in terms of both measured and perceived quality. The overall pipeline is mainly devoted to improve image acquired by low cost imaging sensors, typically present in consumer devices (i.e. mobile phone, web-cams, PDA, etc).

Low cost attacks on tamper resistant devices
1998There has been considerable recent interest in the level of tamper resistance that can be provided by low cost devices such as smart-cards. It is known that such devices can be reverse engineered using chip testing equipment, but a state of the art semiconductor laboratory costs millions of dollars.

Low-cost implementation of acoustophoretic devices
SPIE Proceedings, 2016The use of acoustic energy to manipulate particles and cells (acoustophoresis) is a well-studied and popular technique in microfluidic microscopy applications. This powerful and gentle method has typically required the construction of costly and labour intensive resonating chambers.
