A New Universal Second-Order Filter using Configurable Analog Building Blocks (CABs) for Filed-Programmable Analogue Arrays

In this paper, the design of a universal second-order filter using configurable analog blocks (CABs) for field programmable analog arrays is presented. The configurable blocks are capable of performing integration, differentiation, amplification, log, anti-log, add and negate functions. To maintain high frequency operation, the programmability and configurability of the blocks are achieved by digitally modifying the block's biasing conditions. Using at most four CABs, this article shows that it is possible to design a versatile second-order filter realizing all the standard five filter functions; lowpass, highpass, bandpass, notch and allpass. SPICE simulation results using practical bipolar junction transistor (BJT) parameters confirm the feasibility of using the CABs in designing second-order filters

A Mobile Health Monitoring Application for Obesity Management and Control Using the Internet-of-Things 1Mohamed

Obesity is one of the most serious and dangerous nutritional diseases around the world. Usually, people develop patterns of unhealthy eating that lead to increased body weight and accumulation of fat in the body. This mass happens due to an imbalance between the energy intake from food and energy consumed in the body. One of the primary treatments for this serious health risk include diets, physical activity, weight-loss training and adoption of health programs that promote healthy eating. As such, reliable mechanism to prevent and control the obesity levels is vital. It led many experts and researchers who are interested in the health sector to explore more solutions that help to combat the obesity phenomenon. This paper presents a mobile health application intended to increase the awareness levels of parents and children about the obesity risks and help them to sustain balanced and healthy eating lifestyle. The proposed mobile application is an educational tool for the evaluation of interventions to prevent obesity risk levels. The application is based on the Internet-of-Things approach, which allows tracking food intake, remote capturing and constant monitoring of children data with interactive feedback displayed on the mobile application

Exploring multimodal robotic interaction through storytelling for aphasics

In this poster, we propose the design of a multimodal robotic interaction mechanism that is intended to be used by Aphasics for storytelling. Through limited physical interaction, mild to moderate aphasic people can interact with a robot that may help them to be more active in their day to day activities. In our proposed design Aphasics interact with the iCat robot which recognizes and understands the gestures of Aphasics hereby enabling both of them to participate in a one to one interaction. This interaction helps Aphasics to share and reinforce their experience of storytelling and consequently helps them to reengage in their post-stroke life

Walk 2 win : towards designing a mobile game for elderly's social engagement

In this paper we describe a user-centered approach to designing and evaluating a socially interactive mobile game for the elderly. The objective of the game is to encourage the elderly to socially engage amongst themselves and to make the time that they spend in the community center more enjoyable. The design of the game, known as Walk 2 Win was done for and with the elderly. Two levels of the game (easy, difficult) across two modes (single, multi player) were evaluated with the elderly in a community center over two sessions. Our results show that senior citizens are keen to play simple games having uncomplicated rules as long as they can customize the game according to their whims. Their preference lies in playing games that are enhancements of existing games that they usually play. It was found that the elderly expressed a strong preference and interest to build a team, with for example their grand children. Additionally it was revealed that games for the elderly should incorporate everyone, regardless of gender or their role in the game. The methodological lessons that we came across throughout the design process are also presented
