This paper presents a mid-air tactile display based on indirect laser radiation designed to provide continuous moving tactile sensations along a contour on the skin. The display uses a small laser device with 1064 nm wavelength mounted on a motorized gimbal for the control of laser radiation direction. A laser is irradiated on an elastic medium attached to the user's body, and the medium is made of...
Recently, there has been a growing demand for large-scale computing in various fields. A binary hypercube has been used as an interconnection network topology in parallel computers for large-scale computing. However, the hypercube has a limitation that the degree, that is, the number of links for each node augments rapidly according to the increase in the number of total nodes. This limitation has...
A higher performance DRAM is required by the market due to the increasing of bandwidth of networks and the rise of high-capacity multimedia content. DDR4 SDRAM is the next-generation memory that meets these demands in computing and server systems. In comparison with current DDR3 memory, the major changes are supply voltage reduction to 1.2V, pseudo open drain I/O interface, and data rate increase...
