    • Disclosed is an apparatus for use in marksmanship training. The apparatus includes means for detecting and indicating a position in a measurement plane in the vicinity of a target through which a projectile passes. In addition, the apparatus includes means for measuring the velocity of the projectile in the vicinity of the target. The measured velocity is compared with a predetermined expected velocity to determine if the projectile passed through the measurement plane in free flight or if it had ricocheted prior to passing through the measurement plane. The apparatus will then afford the marksman both an indication of where the projectile passed relative to the target and an indication of whether the projectile has struck the target on a ricochet.
    • 公开了一种用于射击训练的装置。 该装置包括用于检测和指示在射弹通过的目标附近的测量平面中的位置的装置。 另外,该装置还包括用于测量射弹在目标附近的速度的装置。 将测量的速度与预定的预期速度进行比较,以确定射弹是否在自由飞行中通过测量平面,或者是否在通过测量平面之前进行了测速。 该装置然后将为射手提供关于射弹相对于目标通过的位置的指示,以及射弹是否在弹药上击中目标的指示。

    • A target apparatus, having a framework covered by sheets of material to form a chamber the sheets of material being penetrable by a projectile, such as a bullet, fired at the target. A plurality of transducers are positioned at respective spaced-apart locations within the chamber and lying on an arc of a circle, for detecting shock or pressure waves in the chamber caused upon penetration of the sheets of material by the projectile. Time differences between instants of detection of a shock or pressure wave by the transducers are measured, the location at which the projectile penetrated the sheet of material being determined from the time differences. Preferably, a bull's-eye or aiming mark is provided on the target, the center of which is aligned with the center of the circle on which the transducers lie. Apparatus is also disclosed for determining the speed of sound in air within the chamber, enabling the projectile penetration point to be determined with particular accuracy.
    • 一种目标装置,其具有由片材材料覆盖以形成室的框架,所述材料片可以被诸如子弹的射弹穿透,在目标处被击发。 多个换能器被定位在腔室内相应的间隔开的位置并且位于圆弧上,用于检测由弹丸穿过材料片时引起的室内的冲击波或压力波。 测量通过换能器检测冲击波或压力波的时刻之间的时间差,射弹穿透材料片的位置由时间差确定。 优选地,在目标上设置公牛眼或瞄准标记,其中心与换能器所在的圆的中心对准。 还公开了用于确定室内的空气中的声速的装置,使得能够以特别的精度来确定射弹穿透点。

    • Method and apparatus for the deposition of material onto a substrate, the method comprising evaporating material from a source, controlling the dosage of material at the substrate by moving a shutter between an open position and a closed position, with a closing step comprising beginning to decelerate said shutter before reaching the closed position, subsequently thereby bringing the shutter substantially to rest at the closed position. Preferably the motion of the shutter is substantially harmonic with the acceleration of the shutter being directed towards, and proportional to the distance of the shutter from, the point mid-way between the open and closed positions. Contamination is reduced from prior methods and the invention is especially advantageous in molecular beam epitaxy.

    • Transducer assembly having a head and a transducer element contacting the rear of the head.In order to provide an output signal from the transducer element which has a positive value over a wide range of angles of incidence of shock or pressure waves to be detected by said transducer assembly, the transducer element contacts with the rear of the head over a zone which is smaller in cross sectional area taken perpendicular to the direction of propagation of the shock or pressure wave through the assembly than that of the rear of the head. In order to provide electrical connection to the front face of the transducer element which can be a piezo-electric element, it can be mounted in a metal tube with a partly closed end which electrically contacts the front face of the element. In order to positively position the transducer assembly and to inhibit unwanted shock or pressure waves reaching the element, the assembly has a series path of four interfaces of acoustic mismatch of shock or pressure waves, between said head and a body.
