Vom IC zum Mikrosystem

Additionally to the very large scale integrated information processing systems, the second Silicon revolution brings non-electrical functions on the same chip. Chips emerge which are able to sense, to think, to act and to communicate. They are beginning to penetrate into all spheres of human life. Low production costs and mature manufacturing technologies are necessary preconditions for the commercial success. Therefore, going back to the well-proven and costefficient microelectronic technologies and production plants was one of the most important ways towards the broad market penetration of microsystems. However, an extension of the microelectronic technologies is inevitable. In the paper, based on the microsystem development activities of Austria Mikro Systeme Int., problems of microsystem development and solutions are presented for a microelectronic compatible manufacturing environment. With it, the paper describes CMOS compatible products like magnetosensor-IC’s based on Hall elements, mechanical systems like acceleration sensors and specific pre-and post-processing process extensions with service possibilities for external organisations.     

Vom Lehren zum Lernen in Synergie mit Hypermedia

The technical and cultural evolution is generating an information environment which is continually becoming more and more complex: the information society. If it is to be designed in a manner consistent with humanity, generations and internationality, widespread instructional teaching will no longer suffice. In a learning environment in which a change of paradigms from teaching to learning has taken place, new media with a constructive design can generate additional educational values. With hypermedia learning can gain a new quality.

Nonlinear Compensation of a New Noncontact Joystick Using the Universal Joint Mechanism

This paper demonstrates a new noncontact electronic joystick using a single Hall sensor that detects a horizontal vector in the magnetic field. Furthermore, in this paper, the nonlinear characteristics between the output of the Hall sensor and the movement of the joystick bar are modeled and compensated to be linear. The dynamic horizontal vector of the magnetic flux is detected by the Hall sensor while a permanent magnet is rotated with the joystick bar, which has a 2-D detecting area. With the nonlinear modeling equations, the Hall sensor output became linear and accurate for the 2-D joystick movement. Through real experiments, it is shown that the single Hall sensor structure mechanism is superior to the dual sensor structure in sensing 2-D motion without offset.     

Multimedia — Vom Technologie-Push zu einem sozio-kulturellen Konzept

The article presents discussions on the project “Vision of the future” and shows by some examples, how technology push and socio-cultural trends can be harmonized to create new multimedia concepts and solutions.     

Teleoperation of a Mobile Robot Using a Force-Reflection Joystick With Sensing Mechanism of Rotating Magnetic Field

Operators’ intelligent and skillful decisions are necessary for the teleoperation of a mobile robot when there are many scattered obstacles. Among the sensors used for environment recognition, the camera is the most popular and powerful. However, there are several limitations in the camera-based teleoperation of a mobile robot. For example, shadowed and curved areas cannot be viewed using a narrow view-angle camera, especially in an environment with bad illumination and several obstacles. Therefore, it is necessary to have other sensory information for reliable teleoperations. In this study, 16 ultrasonic sensors are attached around a mobile robot in a ring pattern to measure the distances to the obstacles and a collision vector is introduced as a new tool for obstacle avoidance, which is defined as the normal vector from an obstacle to the mobile robot. Based on this collision vector, a virtual reflection force is generated to avoid the obstacles and then the reflection force is transferred to the operator who is holding the joystick used to control the mobile robot. Based on this reflection force, the operator can control the mobile robot more smoothly and safely. For this bidirectional teleoperation, a master joystick system using a two-axis hall sensor was designed to eliminate the nonlinear region, which exists in a general joystick with two motors and potentiometers. The effectiveness of the collision vector and force-reflection joystick is verified by comparing two vision-based teleoperation experiments, with and without force reflection.

Vom Internet zu mobilen Applikationen: intelligente Einbindung von Webdaten mit Lixto

The World Wide Web is the largest database on earth — a huge amount of data and information primarily intended for human users. Unfortunately, data on the web requires intelligent interpretation and cannot be easily used by programs. It requires advanced data extraction and information integration techniques to automatically process data. Lixto technology addresses these issues and enables developers to interactively turn web pages into mobile services.

Von der Chipkarte zum Minicomputer im Scheckkartenformat

The future minicomputer in the size of a cheque card is an extremely complex system, integrated into the widely known credit cards. Such intelligent cards are the key to many different services requiring a maximum level of security. They can be used to encrypt and decrypt stored data on the PC or to encrypt/decrypt transmitted data to the modem. They function as keyless applications for example for your car and your house. You can store a large amount of data very securely on the cards and they remain in your wallet. They can replace cash in almost any application. Thus, they are personal keys as well as high security storage mediums for the information society of tomorrow. The challenge of realizing credit card minicomputers arises in coordinating complex systems and tools and requires highly qualified engineers who cope with quick advances in semiconductor technology and computer aided development systems and finally, based on the latter, with development of ever more complex products.
