摘要： A MEMS scanning device includes more than one type of actuation. In one approach capacitive and magnetic drives combine to move a portion of the device along a common path. In one such structure, the capacitive drive comes from interleaved combs. In another approach, a comb drive combines with a pair of planar electrodes to produce rotation of a central body relative to a substrate. In an optical scanning application, the central body is a mirror. In a biaxial structure, a gimbal ring carries the central body. The gimbal ring may be driven by more than one type of actuation to produce motion about an axis orthogonal to that of the central body. In another aspect, a MEMS scanning device is constructed with a reduced footprint.

摘要： The invention concerns a castable rig and a method for catching crustaceans using a standard rod and reel. The disclosed rig includes an annular ring attached to a harness by means of a plurality of elongate suspension members. The periphery of a generally conical net is attached to the annular ring. A weight is attached to the net and a bait sack is positioned within the conical structure of the net. The bait sack may be integrally formed with the net.

摘要： The instant invention teaches a compact collection lens with finite conjugates for use in coupling the collected energy from a broadband source into a multi-mode fiber. The lens is reflective in nature and provides finite conjugate imaging in one piece. The entrance and exit surfaces are made concentric with the object and image so that on-axis imaging is completely free of chromatic aberrations. The primary is nominally elliptical and is the only surface with optical power in the lens. The secondary is planar and serves to fold the progressing rays back in the original direction. In summary, the invention comprises a monolithic lens composed of four optical surfaces (two reflective and two transmissive) such that the primary and secondary mirrors are annular and the entrance and exit surfaces are predominantly spherical with their centers located at the front and back focal points.
摘要翻译：本发明教导了一种具有有限共轭的紧凑收集透镜，用于将收集的能量从宽带源耦合到多模光纤中。透镜本质上是反射性的，并且在一个部分中提供有限的共轭成像。入射和出射表面与物体和图像同心，使得轴上成像完全没有色差。主要名义上是椭圆形，是透镜中唯一具有光学功率的表面。次级是平面的，用于将进行的光线沿原始方向折回。总之，本发明包括由四个光学表面（两个反射和两个透射的）组成的单片透镜，使得主反射镜和次反射镜是环形的，并且入射和出射表面主要是球形的，其中心位于前焦点和后焦点。

摘要： The instant invention senses shutter blade position indirectly by sensing the position of rotor(s) driving the shutter blade in an electromagnetically driven actuator system. It generally comprehends systems where a plurality of rotors each drive respective blades of a shutter such that the position of each of the rotors is indicative of the position of their respective shutter blades, and combines such systems with non-optical sensors responsive to the rotors which signal the position of the shutter blades based on the position of the rotors. The non-optical sensors used are preferably responsive to the magnetic fields produced by the rotors, and can be advantageously positioned adjacent stator poles associated with the rotors, which stator poles are associated with the open or closed positions of the shutter blades. The sensors are preferably Hall Effect (Hall IC) sensors producing voltages proportionate to and greatest when the pole of a magnet is proximate the Hall Effect sensor. Thus, the system can be arranged with sensors adjacent stator poles associated with a closed blade/shutter configuration, or arranged with sensors adjacent stator poles associated with an open blade/shutter configuration, so that the voltage signal produced is highest/lowest for either a closed/open shutter condition or the opposite.
摘要翻译：本发明通过感测在电磁驱动的致动器系统中驱动快门叶片的转子的位置间接地感测快门叶片位置。它通常理解多个转子各自驱动快门的相应刀片的系统，使得每个转子的位置指示其各自的快门叶片的位置，并且将这样的系统与响应于转子的非光学传感器相结合，基于转子的位置来表示快门叶片的位置。所使用的非光学传感器优选地响应于由转子产生的磁场，并且可以有利地定位在与转子相关联的定子极附近，该定子极与快门叶片的打开或关闭位置相关联。这些传感器最好是霍尔效应（霍尔IC）传感器，当磁体的磁极接近霍尔效应传感器时，产生与电流成比例且最大的电压。因此，系统可以布置有与关闭的叶片/快门配置相关联的定子极的传感器，或者布置有与与开放叶片/快门配置相关联的定子极的传感器，使得产生的电压信号对于关闭/打开快门条件或相反。

摘要： A reflaxicon system comprising two or more reflaxicons, either, neither, or both of which can be formed of solid light transmitting material, is provided and described for use and implementation as objectives, relays, and beam expanders. Each reflaxicon features a central substantially cone shaped surface and a distal surface shaped like a truncated cone with both of said surfaces aligned with and symmetrically arranged around a central axis. In the system provided said central axes are aligned and form the optical axis of the system and further curvatures can be provided to any of said surfaces as well as to incident and exiting system surfaces to provide additional optical effects as required for different applications. Further, the conical surfaces forming the central reflectors can each or both be convex or concave, with ease of construction mitigating in favor of dual concave central reflectors as the preferred embodiment.
