    • A reflective window for providing an indirect optical path to an object including an array having a plurality of reflective elements, each being disposed at an acute angle to the plane of the window and parallel to each of the other reflective elements; each of the reflective elements having a length, along its dimension which intersects with the plane of the window, capable of producing on the window a projection which is at least as great as the distance between each pair of the reflective elements, each of the reflective elements having first and second reflective surfaces for receiving radiation on its first reflective surface and reflecting it to the second reflective surface of one adjacent reflective element and for receiving on and reflecting from its second surface radiation from the first reflective surface of another adjacent reflective element.

    • A process of improving the sensing function of biocompatible electrodes and the product so made are disclosed. The process is designed to alter the surfaces of the electrodes at their tips to provide increased surface area and therefore decreased contact resistance at the electrode-tissue interface for increased sensitivity and essentially includes rendering the tips atomically clean by exposing them to bombardment by ions of an inert gas, depositing an adhesion layer on the cleaned tips, forming a hillocked layer on the adhesion layer by increasing the temperature of the tips, and applying a biocompatible coating on the hillocked layer. The resultant biocompatible electrode is characterized by improved sensitivity, minimum voltage requirement for organ stimulation and a longer battery life for the device in which it is employed.
    • 公开了改善生物相容性电极和如此制作的产品的感测功能的过程。 该工艺被设计成在其尖端处改变电极的表面以提供增加的表面积,并因此降低电极 - 组织界面处的接触电阻以提高灵敏度,并且基本上包括通过使尖端暴露于由 惰性气体,在清洁的尖端上沉积粘合层,通过增加尖端的温度在粘合层上形成一个小丘,并在生物相容的涂层上涂上小丘层。 所得到的生物相容性电极的特征在于其使用的装置的灵敏度提高,器官刺激的最低电压要求以及更长的电池寿命。
