High speed rotational arc sensing is an important method to detect the torch deviation during automatic seam tracking of arc welding. In this paper, a mathematic model of high speed rotational arc sensing is analyzed. Simulations have been implemented in two conditions, namely considering or without considering weld bead profile. The simulation results are consistent with the experimental results. The current waveforms at the beginning of the welding are different from those at middle of the welding because of the formation of the weld bead profile. The signal patterns for seam tracking and end-point detection are proposed. A phase shift between the rotation and the current variation is also discovered in the experiments. The mathematical model can be helpful for the interpretation and improvement of arc sensing systems

This paper presents a novel approach to programming wireless sensor nodes using a graphical programming development environment, LabVIEW. The graphical programming approach used in LabVIEW, popular as a software development environment for PC systems, is extended to embedded applications and sensor nodes, complete with debug and download tools. A modular sensor node platform, Cubix, provides a flexible, programmable target for embedded LabVIEW. Cubix is a modular platform designed for wireless, distributed sensor applications, with options for local sensing, acquisition and logging, data processing, and communication

Availability of low cost and high efficiency sensors and of both wired and wireless transmission networks discloses new opportunities in the field of distributed and collaborative networks devoted to system and environmental monitoring. In the paper such a new architecture is presented which employs smart sensors connected to the transmission infrastructure through TCP/IP protocol aimed at providing a real-time, multi-sensor and multi-purpose network. Preliminary results about the monitoring campaign of the environmental electromagnetic field over the range 100 kHz to 3 GHz are shown together with the evaluation of the statistical distribution of both sampled and rms values

The advent of IEC 61511 has been a good start in improving availability and reliability of safety instrumented loops. Unlike earlier standards like ANSI/ISA S84 and API 14 C, IEC 61511 facilitates mandatory performance based analysis of safety-instrumented functions based on failure data. It is observed that failure data of shutdown valves have been extremely high compared to other elements of safety-instrumented loop. Increasing number of valves in a loop also will drastically affect availability; maintainability, space and cost. Objective of this paper is to improve safe availability of shutdown valve by employing complete stroking instead of partial stroking, increasing diagnostic coverage by using continuous position monitoring instead of limit switches, eliminating the air regulator and selection of proper communication protocol. Some buffering capacity in process is also suggested to facilitate full stroking instead of partial stroking. It is envisaged that SIL 3 level with single shutdown valve in a safety instrumented loop can be achieved with these modifications

In order for wireless sensor networking to provide real- world value, the networks must be able to address several critical requirements: reliability of data transmission, responsiveness to adapt to topology changes, power efficiency, and scalability. Persistent dynamic routing (PDR) is a breakthrough set of techniques that address all of these requirements to support production-grade wireless sensor network implementations. Much of the technology development in the wireless sensor networking field comes out of the traditional static networking industry (i.e. DSDV, DSR, AODV) that is based on a relatively static environment and stable links. As a result, these developments are challenged to address all of the above-named requirements to the level required for production purposes. By contrast, the research on persistent dynamic routing comes out of the sensor research field that presumes an unstable, rapidly changing environment. The relationship among robustness, scalability and responsiveness will be discussed, and the concept of PDR is presented. In addition, the concept of high-capacity wireless sensor network (HC-WSN) is introduced and its benefits are discussed

As parts of the IEEE 1451 smart transducer interface standard are completed, or approaching completion, it is desirable to build and demonstrate hardware and software which implements the standard. The purpose of this paper is to demonstrate that, while a full implementation of the standard may be complex, a minimum and useful implementation is not. It includes an NCAP (network capable application processor) and TEDS reader and writer. Also included is an a/d which converts the analog signal into digital form and a compatible sensor bus
