The integration of on-line monitoring and reconfiguration functions using IEEE1149.4 into a safety critical automotive electronic control unit.
This paper presents an innovative application of IEEE 1149.4 and the integrated diagnostic reconfiguration (IDR) as tools for the implementation of an embedded test solution for an automotive electronic control unit, implemented as a fully integrated mixed signal system. The paper describes how the test architecture can be used for fault avoidance with results from a hardware prototype presented. The paper concludes that fault avoidance can be integrated into mixed signal electronic systems to handle key failure modes

Ultra Low Power IEEE 802.15.4/ZIGBEE Compliant Transceiver
Low power wireless communications is the most demanding request among all
wireless users. A battery life that can survive for years without being replaced, makes it
realistic to implement many applications where the battery is unreachable (e.g. concrete
walls) or expensive to change (e.g underground applications). IEEE 802.15.4/ZIGBEE
standard is published to cover low power low cost applications, where the battery life
can last for years, because of the 1% duty cycle of operation.
A fully integrated 2.4GHz IEEE802.15.4 Compliant transceiver suitable for low
power, low cost ZIGBEE applications is implemented. Direct conversion architecture is
used in both Receiver and Transmitter, to achieve the minimum possible power and area.
The chip is fabricated in a standard 0.18um CMOS technology. In the transmit mode, the
transmitter chain (Modulator to PA) consumes 25mW, while in the receive mode, the
iv
receiver chain (LNA to Demodulator) consumes 5mW. The Integer-N Frequency
Synthesizer consumes 8.5mW.
Other Low power circuits are reported; A 13.56 Passive RFID tag and a low power
ADC suitable for Built-In-Testing applications

NCPV FY 1998 Annual Report
This report summarizes the in-house and subcontracted research and development (R and D) activities under the National Center for Photovoltaics (NCPV) from October 1, 1997 through September 30, 1998 (FY 1998). The NCPV is part of the U.S. Department of Energy's (DOE's) National Photovoltaics Program, as described in the DOE National Photovoltaics Program Plan for 1996-2000. The mission of the DOE National Photovoltaics Program is to make PV a significant part of the domestic economy--as an industry and as an energy resource. The two primary goals of the national program are to (1) maintain the U.S. industry's world leadership in research and technology development and (2) help the U.S. industry remain a major, profitable force in the world market. The NCPV provides leadership and support to the national program toward achieving its mission and goals
The drivers of Corporate Social Responsibility in the supply chain. A case study.
Purpose: The paper studies the way in which a SME integrates CSR into its corporate strategy, the practices it puts in place and
how its CSR strategies reflect on its suppliers and customers relations.
Methodology/Research limitations: A qualitative case study methodology is used. The use of a single case study limits the
generalizing capacity of these findings.
Findings: The entrepreneur’s ethical beliefs and value system play a fundamental role in shaping sustainable corporate strategy.
Furthermore, the type of competitive strategy selected based on innovation, quality and responsibility clearly emerges both in
terms of well defined management procedures and supply chain relations as a whole aimed at involving partners in the process of
sustainable innovation.
Originality/value: The paper presents a SME that has devised an original innovative business model. The study pivots on the
issues of innovation and eco-sustainability in a context of drivers for CRS and business ethics. These values are considered
fundamental at International level; the United Nations has declared 2011 the “International Year of Forestry”
