Vehicle lead-acid battery state-of-charge meter

We describe a state-of-charge, or “residual-capacity” meter for lead-acid batteries that intelligently synthesizes coulometric and terminal-voltage methods in a new algorithm to provide reliable, continuous readout of remaining capacity. Novel electronic circuit design eliminates the need to install a shunt in the vehicle. The meter learns the characteristics of a battery to which it is attached, removing the need for setup, customisation, programming or calibration at time of installation or battery replacement. The meter can thus be installed by unqualified personnel. Initial measurements suggest the design to be robust and accurate

The future of the WTO

This repository item contains a single issue of Issues in Brief, a series of policy briefs that began publishing in 2008 by the Boston University Frederick S. Pardee Center for the Study of the Longer-Range Future.This policy brief reviews the current debates about the future of the World Trade Organization (WTO) and looks at why current discussions on international trade and development are stalled and also on what the implication of this stalemate might be on the longer-term future of the WTO, and of trade and development in general

A through wall doppler radar system: active textile antenna design, prototyping and experiment

Using garments as a platform for electronic sensing and communication systems opens up a wide range of novel and exciting applications. By carefully tailoring the antenna properties and by adopting a dedicated design strategy, a robust wearable antenna system can be obtained onto which all necessary electronics are integrated. In this contribution, the dedicated design for approach of a low-weight, wearable Doppler radar system fabricated on textile materials is presented. The system, fully integrated into a rescue worker's garment, is capable of detecting moving objects behind a barrier. It relies on an array of four textile transmit antennas to scan the surroundings. At the receiving end, an active wearable receive antenna is deployed to capture the reflected signals. It is demonstrated that the on-body system is capable of detecting moving subjects in indoor environments, including through-wall scenarios

Britain's first computer centre for banking: What did this building do?

At the beginning of the 1960s Barclays became the first British bank to open a computer centre. In this paper I trace the life of this building starting with its official opening on 4 July 1961 and ending with its protracted closure a decade later. From initial status as the most advanced bank bookkeeping system in the world serving as a highly visible symbol of the bank's technological power, to a final repurposing of its grandiose reception as a distribution point for pre- and post-decimalisation output, the building's various meanings are revealed. Making use of written, oral, and visual sources I explore the centre's spatial characteristics, its relation to the distributed structure of the branch, and its place as a first dedicated working home for a newly emerging computing subculture. A blend of multiple perspectives internally from the top down and bottom up, and externally from customer and competitor, offer an analysis that uncovers the part played by the first computer centre place in the banking automation race
