A system and method for determining the measurements needed to correctly fabricate prescription eyewear for an individual (10) who is purchasing the eyewear. The individual (10) is provided with initial set of frames. The initial set of frames is fitted to the requirements of the individual to obtain fitted frames (45). An eye exam is also conducted to obtain a proper lens prescription for the fitted frames (45). The individual (10) is imaged while fitted frames (45) are being worn. This creates reference images (44). At some point, the individual (10) may select a subsequent set of frames (56). Once subsequent set of frames (56) is selected, a retailer recalls the reference images (44) and obtains fitting measurements from reference images (44). The online retailer can also recall lens prescription for initial fitted frames (45). Utilizing the fitting measurements, the retailer can custom fit subsequent set of frames (56).
A method of obtaining ophthalmic measurements. An individual wears frames (26). Control simulations are performed to determine average far gaze view line (64), average intermediate gaze view line (62), and average near gaze view line (60). The average far gaze view line (64) intersects the lens plane (27) at second intersection point. The average intermediate gaze view line (62) intersects lens plane (27) at third intersection point. The average near gaze view line (60) intersects lens plane (27) at fourth intersection point. The far region (68) extends from first position above first intersection point to second position (70) below second intersection point. The intermediate region (72) extends from second position (70) to third position below third intersection point. The near region (74) extends from third position to fourth position below third intersection point. The control simulation takes into account the height and stature to fit the natural viewing dynamic.

THROWN FLYING TOY THAT PRODUCES LIFT REGARDLESS OF DIRECTION OF ROTATION
A flying toy (10) that is thrown into flight. The flying toy (10) has a central hub (18) with a central axis (12). A central opening (20) is formed in the hub (18). Wings (22) radially extend from the central hub (18). Each of the wings (22) has a first section (34) that extends from the hub (18), a second section (36) that extends from the hub (18), and a curved section (38) that joins the first section (34) to the second section (36). A shaped opening (32) is defined in each of the wings (22). The curved section (38) in each of the wings (22) is shaped as an airfoil. The curved sections (38) produce lift as air flows over the curved sections (38) in flight.
A system and method for determining the measurements needed to fabricate prescription eyeglasses. A person (18) is imaged wearing the eyeglass frames (20), from a first camera position and a subsequent camera position. This produces images having differing perspectives from known distances. Common measurement points are identified within at least some of the images. The common measurement points undergo positional changes between the images having said differing perspectives. The positional changes of the common measurement points and the known distance to the imaging camera (14) are utilized to map three dimensional coordinates for the measurement points using an actual measurement scale. Fabrication measurements are calculated between the various three- dimensional coordinates in the same scale.
A tumbling toy system (10) where a tumble pin (12) tumbles in a guide track (24). The guide track (24) has two sides (32) and a bottom (33). Each tumble pin (12) rests in the guide track (24) and is free to tumble end-over-end. As the tumble pin (12) tumbles, the ends of the tumble pin (12) cyclically contact the bottom of the guide track (24). Each tumble pin (12) tapers from a maximum diameter at its midplane (27) to a minimum diameter at either end. The maximum diameter of the tumble pin (12) is larger than the distance between the two sides (32). This causes the tumble pin (12) to cyclically contact the two sides (32) of the guide track (24) and become temporarily suspended as it tumbles in place.

SYSTEM AND METHOD FOR OBTAINING LENS FABRICATION MEASUREMENTS THAT ACCURATELY ACCOUNT FOR NATURAL HEAD POSITION
A system and method for determining the measurements needed to fabricate prescription eyeglasses. The system and method take into account how the frames (12) fit naturally on the head and how the person' s posture orients the head alters the line of sight through the lens (14) of the eyeglasses. A sensor unit (16) is provided that is attached to the eyeglass frames (12). The individual then wears the eyeglass frames (12) and moves through at least one situational simulation. The sensor unit (16) generates data that corresponds to changes in orientation. The data is used to determine how person's line of sight is altered by the anatomy of the face and the posture of the head.
