SOCRADES: a web service based shop floor integration infrastructure

Abstract: On the one hand, enterprises manufacturing any kinds of goods require agile production technology to be able to fully accommodate their customers' demand for flexibility. On the other hand, Smart Objects, such as networked intelligent machines or tagged raw materials, exhibit ever increasing capabilities, up to the point where they offer their smart behaviour as web services. The two trends towards higher flexibility and more capable objects will lead to a service-oriented infrastructure where complex processes will span over all types of systems -- from the backend enterprise system down to the Smart Objects. To fully support this, we present SOCRADES, an integration architecture that can serve the requirements of future manufacturing. SOCRADES provides generic components upon which sophisticated production processes can be modelled. In this paper we in particular give a list of requirements, the design, and the reference implementation of that integration architecture.

Ultra-Lightweight Implementations for Smart Devices --- Security for 1000 Gate Equivalents

Abstract: In recent years more and more security sensitive applications use passive smart devices such as contactless smart cards and RFID tags. Cost constraints imply a small hardware footprint of all components of a smart device. One particular problem of all passivesmart devices such as RFID tags and contactless smart cards are the harsh power constraints. On the other hand, activesmart devices have to minimize energyconsumption. Recently, many lightweight block ciphers have been published. In this paper we present three different architecture of the ultra-lightweight algorithm present and highlight their suitability for both active and passive smart devices. Our implementation results of the serialized architecture require only 1000 GE. To the best of our knowledge this is the smallest hardware implementation of a cryptographic algorithm with a moderate security level.

Method and system for mediating enterprise service access for smart devices

Abstract: Techniques are described for mediating enterprise service access for smart devices. A first message may be received at an enterprise service proxy device from a smart device via a first protocol associated with the smart device. It may be determined that the first message includes a smart device request for processing via an enterprise service located at a backend device. An enterprise service request and an associated enterprise request protocol may be determined based on the smart device request and a service adaptation description associated with the enterprise service and the first protocol. The enterprise service request may be sent to the backend device via the associated enterprise request protocol.

Passive interface and software configuration for portable devices

Abstract: A universal passive interface for connecting external systems to smart devices such as cell phones and PDAs. The passive system includes a cradle for receiving a compatible smart device that connects the functionality of the smart device to a wide variety of external systems (e.g., printers, large display, input devices, etc.). The passive interface includes a USB hub, network port, and other common connector ports for peripherals and other systems. The smart device can connect to the passive system via the cradle slot, a tether, and/or wirelessly. The external systems to which the passive system serves at the interface to the smart device include, but are not limited to, large displays (e.g., television), external monitors, input devices such as mice and keyboards, external storage devices, and networks (wired and/or wireless). A wizard allows the user to configure the external systems to work with the smart device.

From online experiments to smart devices

Abstract: Online experiments have been available for more than a decade. The integration of online experiments into collaborative environments is more recent. The wealth of client applications/environments, the versatility of possible interaction protocols/technologies and the needs for more autonomous actions impel the evolution of online experiments to the smart device concept. This paper reviews the evolution of an electrical drive experiment and presents the requirements for turning online experiments into smart devices.

Mobile analytics for emergency response and training

Abstract: During emergency response events, situational awareness is critical in effectively managing and safe-guarding civilians and in-field personnel. To better support both command center controllers and in-field operators, we have developed a mobile visual analytics tool to help enhance situational awareness and support rapid decision making. Our mobile visual analytics tool consists of a 2D/3D visualization component, which shows personnel-related information, situational and static scene-related information, integrated multi media playback functionality for personnel outfitted with cameras, and fast-forward/rewind capabilities for reviewing events. Our current system has been employed in the evaluation of two different scenarios: a simulated evacuation of The Station nightclub fire that occurred in Rhode Island during 2003 and a testing exercise for a rescue operation in an elementary school. Our system has been deployed on a Dell Axim X51v PDA, an OQO 02, and on a Sprint PCS VisionSM smart device PPC-6700.

Shape memory alloy resetable spring lift for pedestrian protection

Abstract: Pedestrian protection has become an increasingly important aspect of automotive safety with new regulations taking effect around the world. Because it is increasingly difficult to meet these new regulations with traditional passive approaches, active lifts are being explored that increase the "crush zone" between the hood and rigid under-hood components as a means of mitigating the consequences of an impact with a non-occupant. Active lifts, however, are technically challenging because of the simultaneously high forces, stroke and quick timing resulting in most of the current devices being single use. This paper introduces the SMArt (Shape Memory Alloy ReseTable) Spring Lift, an automatically resetable and fully reusable device, which couples conventional standard compression springs to store the energy required for a hood lift, with Shape Memory Alloys actuators to achieve both an ultra high speed release of the spring and automatic reset of the system for multiple uses. Each of the four SMArt Device subsystems, lift, release, lower and reset/dissipate, are individually described. Two identical complete prototypes were fabricated and mounted at the rear corners of the hood, incorporated within a full-scale vehicle testbed at the SMARTT (Smart Material Advanced Research and Technology Transfer) lab at University of Michigan. Full operational cycle testing of a stationary vehicle in a laboratory setting confirms the ultrafast latch release, controlled lift profile, gravity lower to reposition the hood, and spring recompression via the ratchet engine successfully rearming the device for repeat cycles. While this is only a laboratory demonstration and extensive testing and development would be required for transition to a fielded product, this study does indicate that the SMArt Lift has promise as an alternative approach to pedestrian protection.

ROME4EU: A Web Service-Based Process-Aware System for Smart Devices

Abstract: Nowadays, process-aware information systems (PAISs) are widely used for the management of "administrative" processes characterized by clear andwell-defined structure. Besides such scenarios, PAISs can be used also in mobile and pervasive scenarios, such as in coordinating operators during emergency situations [1]. In these pervasive settings, due to highly mobility, operators have to be equippedwith small devices, such as PDAs, and to communicate through ad-hoc networks.

RFID: An Ideal Technology for Ubiquitous Computing?

Abstract: This paper presents a review of RFID based approaches used for the development of smart spaces and smart objects. We explore approaches that enable RFID technology to make the transition from the recognized applications such as retail to ubiquitous computing, in which computers and technology fade into the background of day to day life. In this paper we present the case for the use of RFID technology as a key technology of ubiquitous computing due to its ability to embed itself in everday objects and spaces. Frameworks to support the operation of RFID-based smart objects and spaces are discussed and key design concepts identified. Conceptual frameworks, based on academic research, and deployed frameworks based on real world implementations are reviewed and the potential for RFID as a truly ubiquitous technology is considered and presented.

A simulation environment for development and evaluation of smart devices for the elderly

Abstract: This paper describes SISARL simulation environment. The environment is built on Microsoft Windows Workflow Foundation to support the design and development of smart devices and systems that aim to enhance life quality and well being of elderly individuals. To evaluate the usability, design, and implementation of a device, the developer provides as an input for each simulation, an operational view specification of the device and a model of the user (or models of multiple users). The specification describes the operations of the device, intended actions of the user(s) and user-machine interactions in terms activities and workflows. The device and the user are simulated when the specification is executed by the workflow engine. The simulation environment provides extensible libraries of reusable components, including device activities, user activities, and workflow definitions, to ease the efforts in writing operational view specifications of new and modified devices. It also provides a library of user models that can be used to simulate user behaviors, as well as tools for the capture, analysis and display of simulation data. In addition to these components of the simulation environment, the paper also describes ways to use simulation results in the design and development process.

Smart device recordation

Abstract: Valuable information can be retained upon a storage device, such as a flash memory unit. Due to the portable nature of the memory, there can be increased likelihood of theft, less back up of important files not a reliable medium, legal physical transfer of the device between parties, and the like. When an operation is requested to take place related to the device, a check can take place if the operation should be allowed based upon device metadata, such as physical location of the device, device history, and so forth. A determination can be made on if the operation should automatically occur based upon a result of the check. If it is determination that the operation should not automatically occur, then the operation can be denied or a request can be made to an owner of the device on if the operation should be allowed to occur.

Rule Selection for Collaborative Ubiquitous Smart Device Development: Rough Set Based Approach

Abstract: Comparing with general mobile devices, Ubiquitous Smart Device (USD) is characterized by its capability to generate or use context data for autonomous services, and it provides users with personalized and situation-aware interfaces. While the USD development requires more knowledge-intensive and collaborative environment, the capture, retrieval, accessibility, and reusability of that design knowledge are increasingly critical. In the design collaboration, the cumulative, evolutionary design information and design rules behind the USD design are infrequently captured and often difficult to hurdle due to its complexity. Rough set theory synthesizes approximation of concepts, analyzes data by discovering patterns, and classifies into certain decision classes. Such patterns can be extracted from data by means of methods based on Boolean reasoning and discernibility. In this paper, a rough set theory generates demanded rules and selects the appropriate minimal rules among the demanded rules associated to USD physical component design. The presented method shows the feasibility of rough-set based rule selection considering complex design data objects of USD physical components.
