There are many kinds of ions in vacuum arc discharge plasma, which have different distributions space. In this paper, a compact magnetic analyzer is developed for studying the spatial distribution deuterium and metal with occluded electrode. When current about 100 A, device can effectively transfer ion beam good secondary electron suppression, accurately obtain intensity. The titanium TiD elect...

We present the results of calculation and experimental testing of the tunable wavelength terahertz polarization converter represented by a set of plane-parallel birefringent plates with an in-plane birefringence axis. An experimental device has been produced and tested. The calculations show that the effect of interference between the interfaces, including air gaps, may be neglected. The consid...

Aiming at the measurement of cement rotary kiln’s axis, the paper presents the design method of a wireless dynamic measurement system for rotary kiln’s axis. A wireless sensor network monitoring system that can collect multiple parameters was designed, which integrates the detection functions for kiln shell axis deviation, kiln tire axis deviation and drive gear synchronizing signal, and has th...

Most of existing biomedical signal measurement devices measure and evaluate biomedical signals only in a single device. Also, even if the device shows multi-functional characteristics, those biomedical signals can be measured by the selection of users. In this paper, a wristband-style biomedical signal measurement device for u-healthcare systems is implemented to solve the problem mentioned abo...

Suppression of turbulence has been observed in the Large Plasma Device in the presence of flow shear. Using an iris-like setup of biasable metal plates called limiters, azimuthal flow near the edge of the device was achieved. The limiters extend from the inner surface of the device inward, 28.5cm from the central axis, and are set from 0 V to 200 V above the anode. Multiple probing methods incl...

The Bluewand is a small, pen-like device that can be used to control Bluetooth enabled devices by hand-movements. A 6-axis accelerometer and gyroscope system detects the device’s full orientation and movement in space. A Bluetooth wireless link transmits this data to any cooperating device which then executes associated commands or further interprets the device’s movements. Possible application...

Polarization manipulation is essential in almost every photonic system ranging from telecommunications to bio-sensing to quantum information. This is traditionally achieved using bulk waveplates. With the developing trend of photonic systems towards integration and miniaturization, the need for an on-chip waveguide type waveplate becomes extremely urgent. However, this is very challenging using...

In this paper, a 2 DOF haptic yawing joystick for use as the navigation input device in virtual environments is introduced. The haptic yawing joystick can perform a 360°_range yawing motion and ±100°_range pitching motion. The device can support weights of up to 26N along the x axis and 10N along the y axis with 10kHz of sampling rate. For the haptic yawing joystick, an ellipse navigation algor...
