Abstract: A portable, handheld, automatic protection level interpreting cathodic protection meter for testing the level of protection being afforded to metallic structures protected by either sacrificial anode or impressed current cathodic protection systems, or both. The meter is suitable over a variety of environments including salt water, freshwater, and soil. The operator can select both the type of metal to be tested as well as the type of reference electrode that is being used. The meter automatically calibrates data interpretation of the level of protection based on the operator's selections and eliminates any voltage drop error existing between a reference electrode and the structure being protected.

Abstract: A sacrificial marine anode with a water proof encased current tester to alert an operator of proper connectivity, current status of the cathodic protection system for an associated marine structure, and status of current tester power supply is disclosed.

Abstract: The present invention relates to a robotic microscopy apparatus that is able to screen, detect, count and image in an automated and high throughput fashion whole multicellular organisms, tissues, individual cells and groups of cells on or embedded within agar, collagen or other defined matrix. To achieve this, the robotic apparatus of the invention images the samples from the top using a microscope with a long working distance. The invention provides robotic systems for plate handling, biological sample immobilization and microscopic examination. The invention also provides for automatic image acquisition, image storage and display, and image analysis.

Abstract: A system for enhancing images from an electro-optic imaging sensor and for reducing the necessary focal length of a sensor while preserving system acuity. This system uniquely reduces the necessary focal length and enhances images by collecting a video sequence, estimating motion associate with this sequence, assembling video frames into composite images, and applying image restoration to restore the composite image from pixel, lens blur, and alias distortion. The invention synthetically increases the pixel density of the focal plane array. Thus it reduces the necessary size of the projected blur circle or equivalently it reduces the minimum focal length requirements.
