摘要： An artificial system for vision and the like in which a camera views an object and creates signals corresponding thereto which are conveyed to the nervous system of the subject and produce corresponding sensations such as phosphenes in the subject's nervous system, in which the effectiveness of the system in conveying intelligence to the subject is enhanced by converting light-corresponding and dark-corresponding portions of the camera-produced signals into dark-corresponding and light-corresponding portions of the actual sensation-producing signals. Other enhancements include producing a comparatively bright signal of the edge of the object being viewed, the signals applied by a multiplexer which applies the plurality of pulses sequentially to particular locations. Other aspects include providing the subject with a rangefinder which causes sensations that periodically vary, as in brightness, at a rate corresponding to the distance to the object being viewed as well as providing an adjustable signal amplifier to produce a controllable “zoom” effect.
摘要翻译：一种用于视觉等的人造系统，其中照相机观察物体并产生与之对应的信号，其被传送到被摄体的神经系统，并产生相应的感觉，例如受检者的神经系统中的磷光，其中系统的有效性通过将照相机产生的信号的光对应和暗对应的部分转换成实际感觉产生信号的暗对应和光对应部分来增强向传送对象的智能。其他增强包括产生被观察物体的边缘的相对较亮的信号，由多路复用器施加的信号，其顺序地应用于特定位置。其他方面包括向受试者提供测距仪，该测距仪引起周围性变化的感觉，如亮度，以与被观察物体的距离相对应的速率，以及提供可调节信号放大器以产生可控制的“变焦”效果。

摘要： Hydrophilic polymeric chambers for encapsulating biologically active tissue and methods for their preparation. The tissue refers to those essential cellular components of a particular organ that is capable of receiving, modifying or secreting hormones. A device comprising such chamber and such tissue is fabricated and implanted in a living body so that said tissue is permitted normal function without being rejected by the host's immunological system. The viability of the tissue in the device is maintained by a correlation of factors including pore size and membrane thickness of the hydrophilic chamber. To maintain the viability of the tissue, the implanted device allows the inflow of essential nutrients and gases, and outflow of metabolites and products while simultaneously excluding the ingress of cellular components of the host's immunological system.
