In this paper, we present a method for estimating road shape using on-vehicle millimeter-wave radar. The radar detects not only the backscatter from vehicles but also from stationary objects such as crash barriers and sound barrier walls that are generally installed along roads. This indicates that we can estimate road shape by collecting information on the… (More)
The authors propose a system for searching the shape of human hands and fingers in real time and with high accuracy, without using any special peripheral equipment such as range sensor, PC cluster, etc., by a method of retrieving similar image quickly with high accuracy from a large volume of image database containing the complicated shapes and… (More)
In this study, we propose a control algorithm that can estimate gains by a simple method with a double-acting air cylinder and can realize accurate speed control and position control. Specifically, we aimed at quick response and less overshoot by providing PD controller of common bias pressure that can generate passive drag, in addition to the DIP… (More)
When a humanoid robot hand generates a dexterous motion or adaptive behavior, a three-dimensional tactile sensor is indispensable which is as thin and soft as human skin. This study proposed a three-dimensional tactile sensor which enables to use a thin and soft elastic body without requiring any such processing as drawing of pattern on the surface or… (More)
A new type of fluorescence cytophotometer has been developed for multi-parameter cell analysis (Olympus BH2-QRFL). For multi-color fluorescence cytophotometry, this instrument is equipped with four sets of interchangeable filters, each consisting of an excitation filter, a dichroic mirror with a barrier filter, and a measuring filter. For permitting… (More)
In the gesture interface, the technology for detecting positions and the number of nails from the hand image will become an important factor. The intention of this research by our research group is to distinguish between nails and regions that have similar colors to nails, by extracting regions with a color hue similar to nails first and then identifying… (More)
We have investigated the reliability of a fluoride fiber module with a hermetically sealed package for practical optical fiber amplifier use. We confirm that our module has long-term stability under practical environmental conditions and sufficient mechanical strength.
