摘要： A single use camera is preloaded with a roll of magnetically coated film with defined image frames. The camera has an exposure system for selectively exposing an image frame of the film in one of a plurality of image formats. The camera also includes a manually actuated mechanism coupled to a mounted permanent magnet. The magnet is movable to record a magnetic mark on the magnetically coated film at a predetermined location relative to an exposed image frame. The location of the mark is indicative of the image format of the exposed image frame.

摘要： A camera includes an enclosure having a front surface for supporting an optical section relative to an optical axis intersecting an image receiver supported relative to a back surface, and a lens positioned in the optical axis on the front surface of the camera and projecting a field of view forwardly of the camera. A plurality of thin elements are arrayed on the front surface of the camera around the lens in general correspondence with the field of view. Framing accuracy is improved for self portraits and the like by canting each element outwardly from the optical axis at such an angle that an inside surface of every element is visible to a subject positioned within the field of view of the lens.

摘要： A pair of Hall sensors are symmetrically positioned between the poles of a horseshoe magnet. The Hall sensors are mounted in a plane flush with the ends of the magnet faces, and are located equidistant from the centerline of the magnet. A small magnetic object in the field of the magnet, preferably located on the magnet axis, has an induced dipole moment which is detected by the Hall sensors. The small magnetic object dipole field is such that the flux at each Hall sensor is in opposite directions, and by differentially sensing the outputs of the Hall sensors, a signal proportional to the magnetic object is derived. Leakage flux from the magnet as well as the flux of the earth's magnetic field, are in the same direction at both Hall sensors, and their effects are zeroed out by the differential sensing of the Hall sensors' outputs. When the poles of the magnet are drawn across the surface of a non magnetic sheet of conductive material, eddy currents are induced in the sheet by the moving magnetic field. Due to the symmetry of the magnet/sensor arrangement, in a uniform sheet these currents generate identical magnetic fields which result in sensor outputs that cancel. However, a crack or other anomaly in the sheet results in unequal signals at the two sensors, and an output signal proportional to the anomaly occurs.
摘要翻译：一对霍尔传感器对称地位于马蹄铁磁极之间。霍尔传感器安装在与磁体面的端部齐平的平面中，并且与磁体的中心线等距。在磁体领域中，优选位于磁体轴线上的小磁体具有由霍尔传感器检测到的感应偶极矩。小的磁性物体偶极场使得每个霍尔传感器的磁通量处于相反的方向，并且通过差分地感测霍尔传感器的输出，导出与磁性物体成比例的信号。霍尔传感器在两个霍尔传感器处，来自磁体的漏磁通量以及地球磁场的磁通量都是相同的方向，它们的效应被霍尔传感器输出的差分感测清零。当磁体的极被拉过导电材料的非磁性片的表面时，通过移动磁场在片材中引起涡流。由于磁体/传感器布置的对称性，在均匀的片材中，这些电流产生相同的磁场，导致传感器输出取消。然而，片材中的裂纹或其他异常会导致两个传感器发出不相等的信号，产生与异常成正比的输出信号。
