Abstract: The present application relates to an apparatus for controllably rotating an object, such as a baseball or any sporting ball, and methods of using the apparatus for measurement of visual acuity and/or training. Specifically, in certain embodiments, an object is rotated at a selected revolutions per minute (RPM) and a subject's exposure to the rotating object is controlled by illumination and/or controlled exposure, and assessing a subject's ability to recognize the direction of rotation.

Abstract: The present invention relates to a means for creating a visual illusion of directional movement based on stationary motion elements referred to as “motion pixels.” In various embodiments, methods for using the directional illusion are provided, such as 1) the measurement and/or assessment of visual performance in active and virtual reality environments, 2) the measurement and/or assessment of acuity, in conjunction with eye trackers so as to measure visual performance in nonverbal or potentially malingering observers, 3) the enhancement of advertising and marketing by drawing attention to a desired symbol, and 4) the enhancement of images so as to produce the appearance of motion in otherwise stationary images.

In various embodiments, methods for using the directional illusion are provided, such as, for the measurement and/or assessment of visual performance and/or acuity, for evaluating visual performance in various settings, enhancing advertising and marketing by drawing attention to a desired symbol, or enhancing images.

Abstract: A cathodic protection monitoring system for buried metal objects comprising a transponder hard-wire connected to a sacrificial anode and a reference electrode, each of the transponder, the sacrificial anode and the reference electrode being buried underground in close proximity to the buried metal object to be protected, thereby forming a first principal circuit between the sacrificial anode and the buried metal object and forming a second principal circuit between the reference electrode and the buried metal object. The system further comprises a portable transceiver disposed above ground tuned to a frequency of the transponder. Power for operation of the transponder is drawn from the cathodic protection circuit, thereby obviating the need for connections to above ground power supplies.

Abstract: A remote teaching system 2 includes a teacher station 4 and a plurality of student stations 6 which may be located at sites remote from one another. Each station 4, 6 includes a speaker telephone 122, 122' or other voice telephone set which is connectable to a telephone system 124 for voice communication among the various stations. Each station 4, 6 includes a video display monitor 14, 14' such as a television set and a video media player 16, 16' such as a video-tape cassette player connected to the video display monitor 14, 14'. Each student station 6 also includes a video-media-player controller 8', 22' which is connected to the video media player 16' of the student station 6 for controlling the playing of the player. The teacher station 4 includes a video-media-player master controller 8, 22 connected to the video media player 16 of the teacher station 4 for controlling the playing of the player.
