Micro-milling, which is one of the mechanical micromachining methods, shows the potential to make very small parts with three dimensional microstructures. However, micro-milling is usually carried out on a traditional machine tool, which has a spindle with several kilowatts. For micro-milling on a traditional machine tool, most power is consumed by friction, not cutting, resulting in waste of energy...
In this paper a dipole-type RFID tag antenna is proposed and it can be used to detect the mechanical deformation of an object. When the tag antenna is attached to an object, the mechanical deformation of the object and the patch antenna will contribute to the frequency deviation. So we can research and test the impact of mechanical deformation of the RFID tag antenna on its resonant frequency to monitor...
Metal debris in lubricating oil contains abundant information regarding the ageing and wear of mechanical transmission systems. The health condition of the lubricated systems can be indicated by the quantity and size of the metal particles, which may provide very early warnings of faults/ failures and benefit the condition based maintenance. Generally speaking, the quantity of the metal debris in...
For overcoming the problems that bionic robotic fish is energy-limited and its battery is difficult to be changed, we design a real-time energy monitoring and management system, which makes monitoring the energy consumption of the robot possible in real time. The advantages of the system we designed include small size, reliable performance and low energy consumption. Its main functions are energy...
Zero-Degree Detector (ZDD) is a new Detector of Beijing Electron Spectrometer III (BESIII) for both double gamma event detection and luminosity monitoring to substitute the old luminosity monitor. A new luminosity readout is described in this paper which is designed in double width AMC/MTCA form factor with a large Xilinx Virtex5 FPGA in addition to normal electronic signal formation. A FPGA embedded...
Ultrasonic systems are starting to find application in industrial process control systems. Such systems use conventional linear techniques to analyze and/or characterize a chemical reaction. Here, an active acoustic technique combining both linear and non-linear analysis is used for the characterization of a High Throughput Technology (HTT) product. An experimental procedure using a pair of ultrasonic...
The advanced metering infrastructure (AMI) is expected to provide an infrastructure to render the current smart metering functions effectively and efficiently, and also to enable the future AMI-smart grid related functions without the need to change-out the AMI system. The information collection and distribution among customers and utility companies enabled by AMI has advantages in various aspects...
This thesis discusses the establishment and realization of an autonomous biped robot with object tracking function. It firstly analyzes the degrees of freedom (dof), the connections of actuators and links, the locomotion of the actuators, and the configuration of the biped robot. Secondly, it uses RS-232 as the interface for communication and control to allow the robot to receive demands from the...
In this work, we propose a new technique for comprehensive scanner matching to fundamentally improve scanner productivity in a Giga fab. The proposal covers matching solutions for both CD and overlay fingerprints among scanners. CD matching strategy has three main components. The first part is to apply model-based scanner tuning for scanner optics matching. The second part is to apply hotplate-tuning...
System test has been the standard measurement to evaluate performance variability of high-performance microprocessors. The question of whether or not many of the lower-cost alternative tests can be used to reduce system test has been studied for many years. This paper utilizes a data-learning approach for correlating three test datasets, structural test, ring oscillator test, and scan flush test,...
We present an application of an open source platform for wireless body sensor network called DexterNet to the problem of children's asthma. The architecture of the system consists of three layers. At the body sensor layer (BSL), the integrated monitoring of a child's activities, geographic location, and air pollution exposures occurs. At the personal network layer (PNL), a wireless mobile device worn...
We present an open-source platform for wireless body sensor networks called DexterNet. The system supports real-time, persistent human monitoring in both indoor and outdoor environments. The platform utilizes a three-layer architecture to control heterogeneous body sensors. The first layer called the body sensor layer (BSL) deals with design of heterogeneous body sensors and their instrumentation...
This paper presents a novel path selection methodology to select paths for monitoring unexpected systematic timing effects. The methodology consists of three components: path filtering, path encoding, and path clustering. Given a large set of critical paths, in path filtering, the goal is to filter out paths that cannot be functionally sensitized. To explore the space of unexpected timing effects,...
This paper examines the feasibility of employing the new generation fibre optic and piezoelectric sensor systems for comprehensive monitoring of rocks, covering load history monitoring/retrieval as well as damage assessment. A detailed experimental study was conducted on the Bukit Timah granite rock samples obtained from a cavern site in Singapore. The rock specimens were subjected to cyclic loading...
