    摘要： An audio/video surveillance recording system comprising both units having a video camera and units having a dummy lens is disclosed. The use of a dummy lens rather than tinted or mirrored glass on the camera housing provides a greater amount of light to the camera. A unique mounting assembly which lets the dummy units be substituted for the live units without removing the mounting brackets is also disclosed. Both the dummy and live units have illuminated indicators. The system uses weatherproof microphones manufactured using a novel plastic dipping and coating method.

    摘要： A method and system are provided for detecting and monitoring the treatment of eye disease by determining the presence of visual field defects. The method utilizes eyeglasses having a pair of cross-polarizing lenses selectively adjustable for varying the amount of luminance of an Amsler grid as observed by the patient through the eyeglasses. By adjusting the relative polarization of the lenses separately for each eye until the patient is barely able to see the Amsler grid, the sensitivity of the patient's eyes to the presence of scotomas is greatly increased. By having patients record the presence of scotomas while observing the Amsler grid through the eyeglasses, it is possible to screen patients for visual loss associated with various eye diseases, such as atrophic SMD. Recording the existence of scotomas on a periodic basis enables an ophthalmologist to determine whether atrophic SMD may be advancing to hemorrhagic SMD requiring treatment to prevent permanent loss of central vision.

    摘要翻译： 提供了一种方法和系统，用于通过确定视野缺陷的存在来检测和监测眼部疾病的治疗。 该方法使用具有一对交叉偏振透镜的眼镜，其可选择性地可调节以改变由患者通过眼镜观察到的Amsler网格的亮度的量。 通过分别调整眼睛的相对极化，直到患者几乎看不到Amsler网格，患者眼睛对暗点​​存在的敏感度大大增加。 通过让患者在眼睛观察Amsler网格时记录暗点的存在，可以筛选患者与各种眼睛疾病（如萎缩性SMD）相关的视力丧失。 定期记录暗点的存在使得眼科医生能够确定萎缩性SMD是否可能进行到需要治疗的出血性SMD以防止中心视力的永久性损失。
