    摘要： A semi-insulating silicon carbide monocrystal and a method of growing the same are disclosed. The semi-insulating silicon carbide monocrystal comprises intrinsic impurities, deep energy level dopants and intrinsic point defects. The intrinsic impurities are introduced unintentionally during manufacture of the silicon carbide monocrystal, and the deep energy level dopants and the intrinsic point defects are doped or introduced intentionally to compensate for the intrinsic impurities. The intrinsic impurities include shallow energy level donor impurities and shallow energy level acceptor impurities. A sum of a concentration of the deep energy level dopants and a concentration of the intrinsic point defects is greater than a difference between a concentration of the shallow energy level donor impurities and a concentration of the shallow energy level acceptor impurities, and the concentration of the intrinsic point defects is less than the concentration of the deep energy level dopants. The semi-insulating SiC monocrystal has resistivity greater than 1×105 Ω·cm at room temperature, and its electrical performances and crystal quality satisfy requirements for manufacture of microwave devices. The deep energy level dopants and the intrinsic point defects jointly serve to compensate the intrinsic impurities, so as to obtain a high quality semi-insulating single crystal.

    摘要： Embodiments of the invention provide a fiberoptic device that uses a gradient-index (GRIN) lens for focusing a light beam emitted by an optical fiber, but achieves a substantially longer focal length than that of a GRIN lens alone by placing a beam expander (e.g., no core fiber or step-index multimode fiber) between the terminal end of the optical fiber and the GRIN lens to simulate free space therebetween. In one embodiment, a fiberoptic device comprises an optical fiber having a fiber core and an end through which a light beam emits from the fiber core; a beam expander having a first end coupled to the end of the optical fiber and having a second end, the beam expander permitting the light beam emitting from the fiber core to pass from the first end to the second end and to expand from the first end to a larger size at the second end; and a gradient-index fiber lens coupled to the second end of the beam expander to receive the light beam from the beam expander and focus the light beam.

    摘要： A fault in a DC power source, such as a battery string or a string of photovoltaic cells, is identified by detecting a change in an AC component of a residual current of the DC power source. In some embodiments, the DC power source is coupled to at least one DC bus and he methods further include generating an AC voltage on the at least one DC bus. For example, the DC power source may be coupled to a modulated DC bus of an uninterruptible power supply (UPS) system comprising an inverter having an input coupled to the DC bus. The inverter may be configured to generate an AC output voltage and the AC component has a frequency that is a harmonic of a fundamental frequency of the AC output voltage, such as a third harmonic of the fundamental frequency of the AC output voltage.

    摘要： A dumbbell having adjustable inertial resistance load in the field of athletic sports devices is disclosed. The structure of the present invention is characterized in that the hand grip of the dumbbell is provided inside with a rotatable main shaft, the two swing hammer rods and the swing hammers at both ends of the main shaft constitute a normal pendulum, and the two pendulums at both ends of the main shaft are connected through the main shaft, so as to be functionally combined into the function of one eccentric pendulum. The main shaft, the two swing hammer shafts and the swing hammers constitute an eccentric pendulum. The two pendulums fixed at both ends of the main shaft may be adjusted at different angles. In case the angle between the two pendulums is zero degree, upon the rotation of the pendulums, the forces between the hand grip and the hand, besides the mutual force in the up-and-down direction, also include the periodic inertial force in the fore-and-aft direction. In case the angle between the two pendulums is non-zero degree, upon the rotation of the pendulums, the forces also include the periodic inertial force in the left-and-right direction. By adjusting the weight of the swing hammer, the distance from the swing hammer to the main shaft and the included angle of the two swing hammer rods, the amplitude of the inertial force may be adjusted. This inertial force is a resistance load, and functionally speaking, the dumbbell of the present invention has the characteristic of adjustable inertial resistance load.
