作者： Chen, Rain So Taiwan Univ Dept Visual Commun Design Yung Kang 710 Tainan County Taiwan

Design patent map is an important strategic tool for establishing design strategies. Of types of patents, design patents occupy a unique patent field, since design patents are not as definitive as other patent fields. Therefore, the construction of design patent map is extremely difficult. Until now, in world-renowned patent periodicals, studies on design patent map have not been found;thus, this study is very innovative. In this study, design patents from between 2005 and 2007 in the United States were selected, 74 patent samples in the car industry were selected as research subjects. Ten design patent examiners who have an average of 10 years of patent evaluation experience in the Taiwan Intellectual Property Office (TIPO) and 29 industrial designers who have had an average of over 3 years of design experience are enlisted to assist in construction of design patent map. Corporations can use the concrete steps provided by this Study, with the multi-dimensional scale, to establish a design patent map and use this to form patent strategies. This strategic tool will become a new tool for competition for firms facing the knowledge economy era! (C) 2009 Elsevier Ltd. All rights reserved.

In the development of avionics systems, Integrated Modular Avionics is advocated for next generation architecture that needs integration of mixed criticality real-time applications. All real-time applications are processed by integrated avionics processing systems. To guarantee spatial and temporal isolation for these applications, the ARINC 653 standard which defines an interface for avionics real time operating systems provides hierarchy partitioning scheduling schemes. To understand of the operation of evolving avionics processing system instances and standards early in the design cycle, a flexible means is to conduct an analysis through the development of an avionic processing system model. This article focuses on the modeling and the performance analysis of avionics processing systems which based on hierarchical partitioning scheduling. Three modeling domains have been proposed: application model, architecture model, and behavioral model. To evaluate the performance of an IMA-based system, simulation environment based on the discrete event system simulation method has been developed. The simulation captures characteristics of the system such as architecture bottlenecks and system capacity. visualization displays support the modeling framework. The simulation tool helps platform designer, applications developer and system integrator to describe and evaluate different implementation choices.

Flight test data is a critical element for characterizing aircraft performance and status, serving essential roles throughout stages such as design, manufacturing, flight testing, and operations. Generated by onboard data acquisition systems as strict time-series data, flight test data is utilized by engineers and data analysts for computation, analysis, and visualization to assess flight mission outcomes. Traditional client-server (C/S) architecture for data visualization involves reading all data points throughout the entire process and using graphics cards for sampling display. However, as the number of flight test data parameters grows exponentially and data volumes increase, data management applications have adopted distributed storage architectures. Consequently, data analysis and visualization have primarily shifted to browser-server (B/S) architecture modes. A single flight test parameter for one mission can generate tens of millions of data points, often requiring simultaneous display of multiple parameters. Due to browser performance limitations, reading all data points in realtime is impractical. Therefore, a high-fidelity sampling algorithm must be developed, tailored to the specific characteristics of flight test data. This algorithm should extract key feature points, adapt to display resolution, and ensure highfidelity visualization of flight test data, meeting the demands of B/S architecture analysis applications. © 2024 IEEE.

Pinch-and-pull with spatial-temporal energy trajectory: new display concept for in-flight energy management

AIRCRAFT ENGINEERING AND AEROSPACE TECHNOLOGY 2013年第2期85卷 126-135页

作者： Han, Fan Wong, B. L. William Gaukrodger, Stephen Nanjing Univ Informat Sci & Technol Nanjing Jiangsu Peoples R China Middlesex Univ London N17 8HR England

Purpose - The purpose of this paper is to present a new visualization display based on a pinch-and-pull concept with 4D spatial-temporal energy trajectory (4DET), for energy profile management of air traffic, specifically in relation to air traffic control for use in the flight deck environments of the future. Design/methodology/approach - The energetic state of an aircraft may be specified by "fly-by parameters" which include speed, thrust, altitude, configuration, heading and even flight path;real-time knowledge of how such parameters complement or influence each other is essential for the successful execution of complex in-flight procedures. Here, the authors have conducted interviews with pilots and pilot trainers using the cognitive task analysis technique, from which the scope was identified for improving current flight management systems. In particular, pilots reflected a desire for a more innovative means of energy management that strives to utilize and present available flight data in a more efficient, readily-accessible manner. In response to these concerns the authors propose a novel on-board visualization display concept for energy management, which goes beyond traditional confines of defining trajectories in space and time. Findings - Expanding the concept of a 4D spatial-temporal trajectory (4DT) to include the notion of energy, hereafter referred to as the 4DET, automated, real-time, calculations of energy requirements can be incorporated within intuitive, user-interfaced, 3D visualisation displays. Practical implications - An intuitive algorithm and display concept expected to help future ATCOs and pilots with more interactive and reliable control of aircraft energy dissipation in an era of increased information overload. This may be particularly relevant for dealing with stressful flight scenarios such as take-offs and landings, ultimately improving arrival-time accuracy and airport efficiency. Originality/value - Through this 4DET concept the paper

Evaluation of radiation protection effectivity in a cardiac angiography room using visualized scattered radiation distribution

In this study, we devised a radiation protection tool specifically designed for healthcare professionals and students engaged in cardiac catheterization to easily monitor and evaluate scattered radiation distribution across diverse C-arm angles and arbitrary physician associated staff positions-scrub nurse and technologist positions. In this study, scattered radiation distributions in an angiography room were calculated using the Monte Carlo simulation of particle and heavy ion transport code system (PHITS) code. Four visualizations were performed under different C-arm angles with and without radiation protection: (1) a dose profile, (2) a 2D cross-section, (3) a 3D scattered radiation distribution, and (4) a 4D scattered radiation distribution. The simulation results detailing the scattered radiation distribution in PHITS were exported in visualization Toolkit format and visualized through the open-source visualization application ParaView for analysis. visualization of the scattered dose showed that dose distribution depends on the C-arm angle and the x-ray machine output parameters (kV, mAs s-1, beam filtration) which depend upon beam angulation to the patient body. When irradiating in the posterior-anterior direction, the protective curtain decreased the dose by 62% at a point 80 cm from the floor, where the physician's gonads are positioned. Placing the protection board close to the x-ray tube reduced the dose by 24% at a location 160 cm from the floor, where the lens of the eye is situated. Notably, positioning the protection board adjacent to the physician resulted in a 95.4% reduction in incident air kerma. These visualization displays can be combined to understand the spread and direction of the scattered radiation distribution and to determine where and how to operate and place radiation protection devices, accounting for the different beam angulations encountered in interventional cases. This study showed that scatter visualization could be a radiation pr
