In order to design a contactless position sensor using coil impedance, the sensitivity and the linearity of impedance against the displacement are required. Therefore, it is very important to clarify the factors which affect the performance of position sensor. In this paper, the effects of winding density in coil on the sensitivity and impedance linearity are clarified by means of the experimental...
This paper is to measure and analyze a performance - TPS(Transaction Per Second) and TET(Total Execution Time, that is, data I/O processing total time during test) - variation of DRAM-SSD and HDD storage in server-storage N∶1 connection environment. We used to two test method - connection between single server and single storage(1∶1), and between multiple server and single storage(N∶1) - in the SAN...
Although power flow of current power utility network, smart grid system exchange digital information and power flow bidirectional interaction between provider and user. Thanks to communication networks, exchange of information between end user and power suppliers can estimate the power consumption more precisely and stable operation of power utility can be possible. To provide these advantages, importance...
A smart wearable robot glasses system is proposed to assist human visual augmentation in daily life, providing a refined visual recognition result to users from multiple input images of the proposed system. It consists of a glasses-type wearable device with a front-view camera, eye-view camera, mounted display, earphone, and computing unit for signal processing. The scene-understanding process on...
This article focuses on the design and implementation of smart wearable robot glasses for human visual augmentation, which take a role to provide the refined visual recognition result to users of wearing the proposed system. The proposed system consists of a glass-type wearable device with a front looking camera, an eye looking camera, and an earphone, and signal processing units. The scene-analyzing...
The scale of nano objects requires very precise position determination. The state-of-the-art manipulators involve accurate nanometer positioning. This paper presents the design of a capacitive displacement sensor for a nanopositioning application. The challenges of designing a capacitor sensitive to nanometer movements that fits in the area of a few hundred square micrometers are described. Analysis...
