iOS is Apple's mobile operating system and is presently used on the iPhone, iPad, and iPod Touch. The hardware platforms associated with the iOS operating system provide a powerful platform for sensor applications. In this paper, we provide a case study on the development of a digital multimeter (DMM) using an iPod Touch. The DMM case study addresses the major subsystems (hardware, software, and firmware)...
Recent statistics show an increase in environmental disasters, a fact which is also perceivable to the public as reports of avalanches, earthquakes and landslides mount in media coverage. Search and Rescue with modern localization techniques consequently attracts attention from scientific and industrial sides. This paper introduces one part of the I-LOV project, endorsed by the German Federal Ministry...
A new photo retrieval system for mobile devices is proposed. The system can be used to search for photos with similar spatial layouts efficiently, and it adopts an image segmentation algorithm that extracts features of image regions based on K-Means clustering. Since K-Means is computationally intensive for real-time applications and prone to generate clustering results with local optima, parallel...
Long-term chronic conditions pose a significant challenge in modern healthcare systems in terms of a reduction in quality of life and the increased costs associated with their management. The concept of self-management can help address these issues supported through the introduction of home based assistive and rehabilitation telecare technologies. The proposed solution aims to produce a home-based...
This article discusses about Greendroid mobile Application Processor. Dark silicon has emerged as the fundamental limiter in modern processor design. The Greendroid mobile application processor demonstrates an approach that uses dark silicon to execute general-purpose smart phone applications with less energy than today's most energy efficient designs.
Security threats on consumer devices such as mobile phones are increasing as the software platforms become more open and complex. Therefore, hypervisors, which bring potential new secure services to embedded systems, are becoming increasingly important. In this paper, we look into how to design a hypervisor-based security architecture for an advanced mobile phone. Key security components of the architecture...
In this paper, we develop the Mobile Common Component which can get the vehicle information as a detail development of Vehicle-IT Convergence Platform by Android platform based mobile devices (e.g., Smartphone). The Mobile Common Component provides common application programming interfaces (API) for collecting and analyzing the various vehicle information (e.g., vehicle mileage information, diagnosis...
In today's world, ensuring security for important locations is a burning issue. Different surveillance methodologies such as alarm system, CCTV, PC based video system are used to ensure this security. But using all these systems, it is not possible for a person to monitor the security of his or her desired location when they are outside. Now-a-days anybody can communicate with anyone at anytime around...
In this study, a multi-purpose remote controller based on Bluetooth mobile phone (MRCBMP) is proposed to provide users for a convenient control interface. The IR, RF and Bluetooth modules are integrated into the microcontroller module cooperated with Bluetooth mobile phone by Bluetooth module. By MRCBMP, users can control IR, RF and Bluetooth controlled objects without the numerous conventional remote...
Modern Mobile platforms are increasingly complex in terms of power management feature set with the advent of Turbo Boost Technology and other features. Trend has been to develop advanced methodologies related to power and thermal management, adaptive fan speed technologies, optimal power sharing etc. Managing these technologies in an optimized and coordinated manner is becoming increasingly complex...
Along with the development of mobile E-commerce, its security problem received more and more attention, and becomed the main factor that affects its development. To address this, we proposed a new Mobile E-commerce system solution that can be used for mobile payment without changing mobile device hardware configuration by connecting to an special and exteral security electronic device. This electronic...
1D or linear barcodes are the black-and-white-striped codes that can be found on most consumer products. This work evaluates existing 1D barcode scanners for mobile phones on their applicability towards consumers. The tested scanners identify the data stored in these codes, and thus enable users of mobile phones to conveniently access related information from the Internet on the go, without having...
Electronic System Level design has gained momentum in recent years and has found its way into industrial main stream. Using mobile phone platforms we identify historic and upcoming trends in system design. Virtual prototyping has become our main tool to attack the resulting design challenges. This methodology has direct implications on development flow and team setup. We explain basic concepts of...
Home automation and building services systems are integrated in many homes and buildings to meet the needs of comfort, security and efficiency of the customers. On the other hand, mobile devices such as handheld devices and smart phones are providing location-independent access to the Internet and local networks. This paper describes the requirements to combine these two mediums to supervise home...
Mobile communication has been dominated by vertically integrated service provision in an `operator centric model', which has been highly bound to voice and SMS services and organized in a monopolistic competition between few Mobile network operators, MVNOs and SPs. In the recent years we have witnessed a radical change driven by the introduction and further development of smartphones, where we see...
Augmented Reality Systems (ARSs) are a logical evolution of virtual reality systems. This new type of system enriches reality by mixing real elements with electronic information. This paper identifies the common tasks performed by ARSs, the underlying software and hardware components that support them and the most common architectures for ARSs. Subsequently, the paper reviews some ARSs, identifying...
An important problem in creating efficient public transport systems is obtaining data about the set of trips that passengers make, usually referred to as an Origin/Destination (OD) matrix. Obtaining this data is problematic and expensive in general, especially in the case of buses because on-board ticketing systems do not record where and when passengers get off a bus. In this paper we describe a...
WLAN location determination algorithms can be classified into client-based approach and infrastructure-based approach. This paper proposes an infrastructure-based indoor location determination algorithm using access points (APs) as received signal strength (RSS) data collectors. Beside the role of RSS data collector, the APs can simultaneously play the role of communication. In the proposed system,...
As the end user requires more powerful functionality from the mobile device, the complexity of software running on the mobile device is increasing rapidly. Therefore, the performance of hardware components such as processor, memory and storage device which constitute mobile systems has been growing rapidly. On the other hand, battery capacity has shown little growth. Because battery lifetime is a...
The rapid growth in the number of online services leads to an increasing number of different digital identities each user needs to manage. As a result, many people feel overloaded with credentials, which in turn negatively impacts their ability to manage them securely. Passwords are perhaps the most common type of credential used today. To avoid the tedious task of remembering difficult passwords,...
