As a key component of all electrical and electronic equipment, waste printed circuit boards (WPCBs) are an important target for equipment (WEEE) treatment.

This paper examines the policy trends of electronic waste (e-waste) management in Asia. E-waste is a rapidly growing waste stream in the world today and is estimated to be growing at 3–5 % per annum. Fast paced obsolescence in the electronic sector has resulted in the generation of e-waste. There are concerns that e-waste generated in developed countries is ending up in developing countries esp...

Refrigeration service personnel have used leak detection equipment for years when servicing refrigeration equipment. In the past, leak detection typically was only concerned with leak pinpointing, either with an ultrasonic device, soap bubbles, dyes, thermal conductivity, or other electronic devices. Today, refrigerant leak detectors exist not only for pinpointing leaks, but also for monitoring...

A major part of the study of coupling paths between mobile communication systems and electronic equipment is the prediction of the level of EMI incident of equipment ports due to external cables. At mobile radio frequencies external cables are generally greater than a wavelength in length and may be the dominant coupling path of EMI into equipment electronics. A two year work package was undert...

A design rationale for introducing electronic equipment for student interaction in lecture theatres is presented, linking the instructional design to theory. The effectiveness of the equipment for learning depends mostly on what pedagogic method is employed: various alternative types are introduced. Prospective studies are outlined for exploring its use over new ranges of application. Rival vie...

A dynamic compression testing system, consisting essentially of a pendulum, abutment, and electronic recording equipment, was built by the Laboratory for testing package cushioning materials. The tests simulate the loading of an item in a cushioned package when the package is impacted. The characteristics, limitations, and theoretical aspects of each component of the instrumentation are present...

Article history: Received 26 June 2015 Received in revised form 23 November 2015 Accepted 30 November 2015 Available online 7 December 2015 In areas with hot weather, photovoltaic systems can be used to help relieve the peak demand caused by air conditioning equipment. Users, however, are reluctant to invest in solar technology, arguing that the equipment commercially available is unreliable be...

Part I of this paper showed that a field commander can expect approximately 65% of his unprotected electronic medical equipment to be damaged by the electromagnetic pulse (EMP) from a single nuclear detonation as far as 2200 km away. Using computer modeling, field-expedient ways to minimize the effects of EMP were studied. The results were: (1) keep wiring near the ground, (2) keep wiring short...

Although the “usual, customary and reasonable” concept may have been reasonable and workable as a basis for [physicians] billing individual patients, it has been a failure as a basis for reimbursement from insurance funds. Because it contains none of the limits or standards that are applied to other services covered by insurance, the charges for medical services have escalated, with little or n...

One area of biomedical instrumentation that is becoming increasingly familiar to the general public is that of patient monitoring. Here electronic equipment provides a continuous watch over the vital characteristics and parameters of the critically ill. In the coronary care and the intensive care units in the hospitals, thousands of lives have been saved in the recent years because of the caref...
