To date, the objective of creating pleasurable products has concentrated on designers articulating and interpreting user needs as part of the product creation process. This paper explores approaches to enable users to adapt, modify, specify or create products to match their needs directly. Using the potential of new technologies, active consumers can now(More)
This work presents a novel simulated model for a wireless data acquisition system. The system reads analogue information provided by two sensors and can be used for medical purposes. Real data has been obtained and a simulation of the two signals coming from both pH and pressure sensors embedded in the system has been employed. The created model contains(More)
The aim of this study is to model and design an efficient wireless system that is easy to integrate with other technologies or infrastructures at a low cost. The system would read analogue information recorded by a biomedical sensor in a transmitting unit attached to the patient. The recorded data are converted digitally using analogue-to-digital converter(More)
The aim of this study is to model and design an efficient wireless system that should be easy to integrate with other technologies or infrastructures at a low cost. The system is reading analog information recorded by a biomedical sensor in a transmitting unit attached to the patient. The recorded data is converted digitally using ADC and sent to FSK(More)
OVERVIEW In December 2000 the White Paper 'A New Future for Communications' set out the government's vision and objectives for communications in the 21 st century. A key part of the vision included radical changes in spectrum management and the switchover from analogue to digital broadcasting. The White Paper addresses issues of fundamental importance(More)
In this paper, a dual loop CMOS phase locked loop (PLL) synthesizer with a wide operating frequency range for wireless low power medical systems is presented. A new low power, high speed, low noise phase frequency detector has been designed. The self-adjusting charge pump is a single-ended drain switching circuit and wide swing cascode current mirrors have(More)
Health, leisure and beauty activities are increasing in popularity in the United Kingdom, with a particular emphasis on self-help and alternative health practices. One product type that has increased sales with this expansion is the hand held electric massager. These are products that use vibration as a means of alleviating muscular strains and pains, as(More)
In this paper, a clock management CMOS PLL with full period phase-shifting of the divided clock is presented. The full-period phase-shifting is performed by generating a multitude of unique divided clock signals evenly spaced in time over one period of the divided clock and re-synchronising with the various oscillator output phases. Low swing current(More)
