Abstract
Purpose
The purpose of this paper is to propose a method to automatically generate individualized body size measurements from cloud point of a body scanner. It aims to propose a fast, reliable, and unambiguous method to obtain human body measurements for use in the garment industry.
Design/methodology/approach
Based on a previous study by the authors, geometric features on the scanned body are identified by computerized algorithms through mathematical definitions. Feature lines situated on the human body surface are created as polylines that pass through the body's features and three types of computer measurements (tape‐measurement, contour‐measurement, and linear‐measurement) are provided.
Findings
By dividing the body surface into rectangular patches using the feature lines as boundaries, the body can be reconstructed easily with a minimal amount of triangles while retaining the essential shape. The proposed measuring method applies to most manual measurements used in the garment industry. The authors evaluated the anthropometry variations of the same subject to explore the reliability of the proposed method. It was found that the precision of the method is well below the standard requirement of the traditional manual method.
Research limitations/implications
In this research, subjects were scanned in standing pose; this pose minimizes regions obstructed by body parts and permits maximal acquisition of as many key landmarks. Since the features are identified by geometric analysis without the need for marker attachment, measurements of the required sitting position are impossible to obtain in the current study.
Originality/value
Resolution of meshing can be changed according to application requirements. Contrary to the traditional manual method, efficiency and precision are the advantages of the present method.

Abstract
This chapter explores the extent to which an innovator is able to capture innovation rents. After examining the two main drivers of such rents, the strength of the appropriability regime and the ownership of specialized complementary assets, the chapter examines how their interaction is so critical in affecting imitation, commercialization options, and firm performance. After reviewing the underlying conceptual framework and empirical evidence, and using a perspective that cuts across both time and industries, the authors then discuss the implications of innovation profits for the resources to be devoted to the discovery of new or improved product and processes.

Abstract
Purpose
The purpose of this paper is to use bibliometric analysis to forecast RFID technology and uses the adoption of barcode scanner to model the RFID scanner adoption in the US retail market.
Design/methodology/approach
Forecasting emerging technologies and identifying the rate of diffusion of products based on these technologies is difficult because of lack of data. This paper uses techniques such as bibliometric analysis and Bass model based on analogous products.
Findings
The authors were able to come up with a good Bass model for the adoption of RFID scanners in the retail sector. And according to the Bass model it appears that it will take at least seven or eight years for the retailers to adopt to this new technology at their point‐of‐sale.
Originality/value
This paper attempts to use bibliometric analysis and Bass model for forecasting technologies and provides a new research discussion as results from these two are compared.

Abstract
The closed loop galvanometer‐based optical scanners continues to be an advanced technology for the integration and enabling of a broader range of laser system applications and uses. Advances in the technology have provided major improvements in galvo positioning speed, accuracy, size and cost. This paper will introduce the benefits, operating ranges and recent advances in galvanometer technology for scanning applications along with some of the other components and issues related to system design for high performance scanning applications. Several different actuator and position detector technologies and designs will be presented including moving coil actuators, moving magnet actuators and patented capacitive and optical position detector designs that offer positioning speeds as fast as 100 μs and positioning repeatability to single microradians. The performance and system design trade‐offs that one should consider during the selection of the appropriate galvanometer technology and the optical systems design will be discussed along with a performance comparison of the galvanometer to other optical scanning technologies.
