Abstract: The present invention is a method for evaluating visual acuity of a user, performed on a computer connected to a server via an Internet. After the evaluation starts, the user is asked to provide information including a name, a brief medical history and the eye prescription information. The evaluation of the user is performed by providing the reading, color determination, distance, dyslexia, peripheral vision, and depth perception tests. A treatment suggestion is produced indicating that no further action is necessary, medical intervention is necessary, or that a vision problem is detected and may be corrected by eyeglasses. The selection allows the user to select eyeglasses frames, order eyeglasses, and repeat the evaluation after the eyeglasses are received.

Abstract: A method for interactively selecting and displaying a distribution of all data fields in a selected database. The primary function of the methodology is to allow a user to view the data contained within a selected database in a graphical format. Additionally, the user has the capability of selecting specific sets of data for more detailed display as well as determining the effect of the selection on all remaining data fields which comprise the selected database. The first step in the process is the accessing of the particular database from the host system. Once the selected database has been accessed, a distribution matrix for each field in the selected database is constructed from the data contained within the selected database. The distribution matrix is then graphically displayed on any type of graphical display unit. From this initial graphic display, the user can make various selections for detailed graphical display and study and analyze the data structure and data content of the database.

Abstract: Apparatus for testing the strengths of muscle and muscle groups of a person. In use, an inflated pressure pad is engaged with a body area, and a force from a muscle or muscle group is applied to the pad. This force is sensed and a signal representing that force is displayed. The pressure pad is connected to the guide so that the pad may be fixed in a multitude of different positions to engage many different body areas subjected to forces from a multitude of different muscles and muscle groups.

Abstract: A method for testing isolated muscles for comparative strength and endurance using an air bag to measure upon the application of force by the muscle the maximum pressure reached and maintained for a preselected period of time.
