  • Patent number: 9539472
    Abstract: Balls for team and individual sports include a motion graphic that provides enhanced perception of ball rotation. The motion graphic is typically defined with a visual characteristic that contrast with a ball casing. The motion graphic includes first and second termination portions that are coupled by a connection region. The first and second termination portions are symmetrically situated with respect to a longitudinal axis and are asymmetric with respect to axes perpendicular to the longitudinal axis. The motion graphic and the ball casing can be provided with substantially opposite colors selected to exhibit similar or substantially the same reflectivities.

  • Publication number: 20160320302
    Abstract: An index value is calculated for rating an eyeglass with respect to protection against UV hazard. The index value is based on an integrated UV transmission value through the eyeglass and an integrated UV reflection value related to a back face of the eyeglass. Thus, the index value takes into account actual wearing conditions where UV eye exposure is due either to transmission through the eyeglass or reflection on the eyeglass back face. Respective index values obtained for a set of eyeglasses allow easy sorting of the eyeglasses with respect to UV protection efficiency.

  • Patent number: 8678582
    Abstract: A method of making a protective shield is provided. The method comprises molding an arcuate lens blank having an optical center displaced from an apex of the lens to a position near or beyond the edge of the protective shield. This reduces the object shift as wearer of the lens shifts gaze from a normal straight ahead line of sight to an activity specific line of sight that is vertically displaced from the normal straight ahead line of sight.

  • Patent number: 8491119
    Abstract: An anaglyphic image presentation system is provided to evaluate and train a user's depth perception abilities. In embodiments, anaglyphic image target components are presented to a user on a display device. The image target components are then viewed by the user through a set of transmission filter lenses. The transmission filter lenses present and block one or more target components based on the peak wavelength transmission associated with each lens. As a result, a user perceives an anaglyphic target image that is resultant from the perceived image target components when viewed through the transmission filter lenses.

  • Patent number: 8360905
    Abstract: Sporting items such as soccer balls include a casing region and a graphic region that are defined by enhanced-visibility colors (EVCs) that are substantially complementary. Such EVCs can be selected to avoid colors associated with color confusion in color deficient individuals. In addition, such colors can be selected based on total reflectances to obtain a predetermined luminance contrast. EVCs can be selected based on separations of color coordinate locations using CIE chromaticity coordinates or CIE L-a-b coordinates or otherwise selected. Color selection can include consideration of anticipated viewing backgrounds in a general setting, or colors can be customized for a particular location and particular illumination conditions.

  • Patent number: 8303442
    Abstract: Sporting balls with enhanced visual acuity, casings for sporting balls with enhanced visual acuity, and methods for enhancing visual acuity of a soccer ball are described. In embodiments, the sporting ball has an exterior with a substantially spherical surface including a first pole opposing a second pole and an equator circumferentially intermediate the first pole and the second pole. Additionally, in embodiments a first exterior region of a first color may include a first hub section oriented at the first pole generally opposite a second hub section oriented at the second pole on the substantially spherical surface. The first hub section may have one or more first hub spokes extending spherically outwardly therefrom toward the equator, and the second hub section may have one or more second hub spokes extending spherically outwardly therefrom toward the equator. Further, in embodiments, the sporting ball may have a second exterior region of a second color.

  • Patent number: 8272070
    Abstract: Conical face shields, sports helmets, and methods for orienting a conical face shield in a sports helmet are described. In embodiments, the conical face shield has at least two opposing arcuate edges, at least two opposing side edges, and a shield. The arcuate edges each have a first end, a second end, and an edge surface extending between the first end and the second end. Further, the edge surface of the first arcuate edge and the edge surface of the second arcuate edge include an arc segment and the arc segment of the edge surface of the first arcuate edge is part of an ellipse with a greater semi-minor axis than the semi-minor axis of the ellipse forming the arc segment of the edge surface of the second arcuate edge. In various other embodiments, the conical face shield may be horizontally and/or vertically tapered.

  • Patent number: 8104891
    Abstract: A face protector includes a one piece shield in which an optical center is displaced away from the normal straight ahead line of sight toward an activity specific line of sight to minimize image shift that occurs when a direction of gaze passes across the edge of the shield. An apex of the shield is formed at a forwardmost point of the shield, or a virtual extension of the shield, when the shield is in an as worn position on a wearer. In particular examples, an optical axis extends through the optical center, at a non-zero angle to the normal straight ahead line of sight and substantially parallel to the activity specific line of sight, with the optical center being placed away from the apex. In particular examples, the optical axis is closer to (or coincident with) an activity specific line of sight of one of the right or left eye. The face protector is particularly useful in activities such as sports, for example hockey, football, or baseball which involve activity specific lines of sight.
