Abstract: A trail camera that provides improved image capture performance in no-light or low-light conditions by using an image sensor that is sensitive to low-light conditions and has a sensitivity range encompassing visible and near infrared wavelengths. The image sensor may produce monochromatic image signals to be more sensitive and provide higher contrast imagery in both day and night conditions. The trail camera may use multiple communications channels to wirelessly communicate both locally and via a wide-area communications network. The trail camera may have a wide field-of-view, and further incorporate a motion sensor that has a like, aligned field-of-view. The trail camera may communicate image data, both still images and video images, to a remote user over the wide-area communication network. The trail camera further may transmit captured video images to a remote user without material time-shift, allowing the user to monitor a targeted area, day or night, in real-time.

Abstract: An automated ophthalmic system is disclosed that is utilized to examine the eyes of a subject. A refraction system measures a refractive error of each eye and identifies a lens to correct the refractive error detected. A display presents one or more of an optotype, a chart, a test and a function to the subject to ascertain the refractive error. An interface device receives a voltage signal from the refraction system, converts the voltage signal into one or more ASCII characters, and communicates the one or more ASCII characters to the display to present the one or more of an optotype, a chart, a test and a function.
