  • The IEEE 1451.4 standards defines an architectural model for interfacing smart transducers for sensors & actuators. This standard allows analogue transducers to communicate their identification and calibration data in a digital format. A digital format is called TEDS(transducer electronic data sheet). However, the standard template of IEEE 1451.4 TEDS do not supports gas sensors to use in electronic nose system such as may sensors. In this paper, a solution to standardize sensors for electronic nose systems is presented.

  • TETRA Enhanced Data Service (TEDS), which is an upgrade version of narrow-band ETSI TETRA Release 1 system, can support high speed packet data services in frequency selected fading channel. The performance of M-QAM transceivers employed in the TEDS is significantly affected by the accuracy of channel estimation. In this paper, we consider the design of a decision-directed channel estimation scheme robust to fast fading by estimating the channel by means of a per-survivor processing (PSP) method. The performance of the proposed channel estimation scheme is verified by computer simulation.

  • It is important to define a standard method to store basic sensor information, such as the type and the structure for an piezoelectric actuator and there is no such method defined in the IEEE 1451.4 transducer electronic data sheet (TEDS) so far. The major challenge is to choose a suitable standard template that can be used with actuators for piezoelectric devices. In this paper, we propose a new template TEDS and the structure of interface for IEEE 1451.4 for piezoelectric actuators.

  • In this paper, we addressed the IEEE 1451.x that can organize a sensor network for efficient measurement system. IEEE 1451 provides standard interface, specification and Object model for example Network Capable Application Processor(NCAP), Transducer Electronic Data Sheet(TEDS), Smart Transducer Interface Module (STIM) and so on. Especially IEEE 1451.2 defines the TEDS Formats and STIM. The TEDS makes transducer to be used independently from device. NCAP makes the component of measurement system to be handled as an object. Therefore each function block constructs system by using Add-on. IEEE 1451.x can be expend the system with Add-on and Plug-and-Play by using smart sensor and connected with current network. We expect that this method can provide the efficiency and convenience when using the measurement system.

  • Ubiquitous computer can be interfaced with many several peripheral devices for information acquisition. Users should be able to easily use these devices without considering when these devices were interfaced, how to use these devices, and interoperability issues (such as plug and play, the installation of device drivers, and so on). Further, computers and their users need an interface technology that provides five-senses information (the recognition and expressions of the user) such that multimodal interaction can be enabled. In this paper, we proposed an IEEE 1451 standard that uses a smart interface standard for interfacing devices with ubiquitous computer. IEEE 1451 describes the property information of a transducer in the transducer electronic data sheet (TEDS). Further, by using the TEDS format, the interoperability between devices can be enabled by means of the plug-and-play function; it also makes the inconvenient installations of device drivers unnecessary.

  • The IEEE 1451 publication are available, this standard defines interface between sensor and processor, and plug and play in processor is possible. Also, Intelligence of sensor was possible because sensor includes transducer electronic data sheet (TEDS). In IEEE 1451 standards, IEEE 1451.4 is suitable standard in single sensor, and IEEE 1451.2 is suitable standard in multi-sensors (array sensor). In this paper, apply IEEE 1451 to electronic tongue system. In the case of electronic tongue system, because array sensor is used, it is that complex and difficult to apply IEEE 1451.4 that is standard for single sensor. In this paper, apply IEEE 1451.2 for array sensor to design of electronic tongue system. Communication interface method of IEEE 1451.2 for electronic tongue system is presented, and implemented TEDS of electronic tongue system.

  • This paper is the second part of a series of the research about the Teddy boy style which is to examine various fashion changes in subcultural styles in 1900s. The main concern of this research is to investigate the creation and meaning of the Teddy boy style, how it interacted with the elements of class and generation and how the materials needed by the group constructed and appropriated into the visible systematic cultural form of correspondence. The Teddy Boys are the first recognized members of the British youth culture, which is known as the new Edwardian because of their dress. They had created the concept of the "teenagers," which forms the basis of the sense of a "generation" in the 20th century. The Teds set the style that would be used and modified in the following generations. They adopted the Edwardian style of the upper class, and changed it into their own style by modifying it and adding to it some other elements. The Teddy boys style is a special version of the sartorial appropriation encountered in the sphere of the fashion history. It actually began immediately after the war by the upper class youth far from the working class neighborhood. In the late 1953, the elitist aura surrounding the Edwardian suit was suddenly shattered. Within just a few months, the Edwardian suit became a source of social anxiety and the focus of a symbolic battle. Although the Edwardian look had initially went back to the upper class root, it became a symbol of rootlessness. In appropriation of this image, The Teddy boys were also rejecting the sartorial conformism of the English working class with its modest tradition. In this respect, the Teds effected the ascent or fall of the working class in the area of fashion. The Teds dress was not a merely borrowed fashion, but was a bastard fashion in the form of American trends, the Zoot suit. At this time members of the working class possessed only work dress for the week and waist suits for the Sunday outings. Teds broke this pattern, and developed the working class dandyism of wearing clothes simply to show off. The results were that they succeeded in opening the teen market, and popularizing a working class style for the first time in British history. The Teds became the first British street style with ties music, and remain as an symbol of the rising of a new age of values and styles.f values and styles.

  • IEEE 1451 standard defines an interface for network and transducer. In this paper, We propose an architectural model to configure data acquisition system and wireless smart sensor node based on IEEE 1451 standard. Proposed Network Capable Application Processor(NCAP) supports the task of data acquisition and communication for smart sensor node and network. The NCAP is able to reconfigure without interrupting the functionality of the wireless sensor node and receives the critical information of transducer using the DB. Smart sensor node is able to provide the basic information of sensor in digital format. This digital format is called Transducer Electronic Data Sheet(TEDS), is capable of plug-and-play capability of wireless sensor node and the NCAP. We simplify the format of TEDS and template to apply to wireless network environment. information of TEDS and template is transmitted using ad-hoc routing. This study system uses body temperature sensor and ECG(Electrocardiogram) sensor to provide the medical information service. The format of template is selected by data sheet of the sensor and reconfigured to accurately describe the property of the sensor. DB of NCAP is possible to register new template and information of the property as developing new sensor.
