    • In one embodiment, an efficient method is presented for aerial searching for a small thermal target in a search area, such as a single person in open water, using two thermal imagers or "cameras" coupled with a computer which presents data from the system to a human user for inspection. One of the two thermal imagers has a very wide field of view (WFOV) fixed forward of or below the aircraft. The other, narrow field-of-view (NFOV) imager has a high zoom capability but its field of view can be reoriented to geo-point to a location on command. The WFOV thermal imager collects images rapidly so that no individual image is blurred due to changes in the field of view (FOV) on the time-scale of the image capture. The images are geo-registered using information from a global positioning receiver as well as the current altitude, roll, pitch, yaw, and velocity of the aircraft. As the aircraft moves and the FOV in the WFOV thermal imager changes, the computer averages the amplitude of the thermal radiation detected from each geo- registered position on the water below using the captured images continuously and in real time. The signal from a thermal target in the water is integrated while the background is relatively suppressed, enhancing the signal-to-noise ratio for the target as the square root of the number of images collected in which the target appears. A target which is much smaller than the area covered by a single pixel or that even has a thermal contrast below the noise equivalent temperature difference of the WFOV thermal imager can be detected. Thermal anomalies which have a signal commensurate in amplitude and spatial extent to the object of the search are selected by the system and their coordinates are relayed to the NFOV thermal imager. The NFOV thermal imager zooms into these locations sequentially and presents the image information to the human user who can then either reject or verify that the subject being imaged is the object of the search.
    • 在一个实施例中,提出了一种有效的方法,用于使用两个热像仪或与计算机耦合的“摄像机”来搜索搜索区域中的小热目标,例如开放水域中的单个人,从而将来自系统的数据提供给 用户进行检查。 两个热像仪之一具有非常广泛的视野(WFOV),固定在飞机前方或下方。 另一个狭窄的视野(NFOV)成像器具有很高的变焦能力,但其视野可以重新定位到地理位置。 WFOV热像仪可快速收集图像,使图像捕获时间尺度上视场(FOV)的变化不会造成任何图像模糊。 使用来自全球定位接收机的信息以及飞行器的当前高度,滚动,俯仰,偏航和速度来对地图进行地理登记。 随着飞机移动,WFOV热像仪中的FOV发生变化,计算机将使用捕获的图像连续和实时地平均从下面的水下的每个地理注册位置检测的热辐射的幅度。 来自水中的热目标的信号被集成在背景被相对抑制的同时,将目标的信噪比提高为目标出现的图像数目的平方根。 可以检测到远小于由单个像素覆盖的区域或甚至具有低于WFOV热像仪的噪声等效温度差的热对比度的目标。 通过系统选择具有与搜索对象的振幅和空间范围相称的信号的热异常,并将它们的坐标中继到NFOV热像仪。 NFOV热像仪顺序放大到这些位置,并将图像信息呈现给人类用户,然后用户可以拒绝或验证正被成像的对象是搜索对象。

    • The present invention provides an ozone generating system that combines single-use elements or segments with an extended use fixture that is used to activate the single-use elements. One embodiment of the invention consists of a strip of proton exchange membrane (PEM) (501) having the ozone producing catalyst applied directly onto one side of membrane. Optionally, the application of this catalyst may be divided into segments or patches, wherein each segment represents the limited-use portion of the ozone generator. Each segment may be advanced into a fixture that provides the balance of the electrochemical system required for operation of the ozone generator. This balance of system may include additional subsystems, with a power supply, water source, electrical contacts (505, 506), electronic controllers, sensors and feedback components, being typical examples. After an individual segment is advanced into the operating fixture, the membrane may be dehydrated by a water source and electrical contact made to the positive (anode) face of the membrane having the ozone generating catalyst and to the negative (cathode) side of the membrane which may also include a catalyst layer.
