Abstract: An adjustable helmet includes a first shell, a second shell, and a size adjustment mechanism. The first shell includes a first side portion and a second side portion. The second shell is positioned between the first side portion and the second side portion. The first side portion and the second side portion of the first shell (a) at least partially overlap the second shell and (b) are laterally flexible with respect to one another to facilitate adjusting a size of the first shell between a minimum size and a maximum size. The size adjustment mechanism includes a tensioner extending between the first side portion and the second side portion. The size adjustment mechanism facilitates ratchet-less and infinite adjustment of the size of the first shell between the minimum size and the maximum size without requiring user manipulation of the size adjustment mechanism.

Abstract: An impact absorbing pad includes a first layer and a second layer. The first layer has a first body-facing surface configured to be positioned adjacent a garment and a first outer surface opposite the first body-facing surface. The first layer comprises a first foam having a first density. The first layer defines a first plurality of voids that extend through the first layer at a first plurality of positions. The second layer has a second body-facing surface positioned adjacent the first outer surface of the first layer and a second outer surface opposite the second body-facing surface. The second layer comprises a second foam having a second density that is different than the first density. The second layer defines a second plurality of voids that extend through the second layer at a second plurality of positions. Portions of the first outer surface of the first layer are visible through the second plurality of voids of the second layer.

Abstract: An adjustable helmet includes a main shell having a first side portion, and a second side portion. The first side portion and the second side portion are laterally flexible with respect to one another. The adjustable helmet includes a secondary shell coupled to the main shell at a location between the first side portion and the second side portion. At least a portion of the first side portion and at least a portion of the second side portion each extends over at least a portion of a top surface of the secondary shell. The adjustable helmet includes a tensioning device. A first end of the tensioning device is coupled to the first side portion and a second end of the tensioning device is coupled to the second side portion so as to provide a tension force between the first side portion and the second side portion.

Abstract: A base assembly for a batting tee includes a base having a base guide path formed in an upper surface of the base, and a track plate positioned such that the track plate covers at least a portion of the upper surface of the base. The track plate includes a first segment and a second segment that surrounds at least a portion of the first segment. A position of the first segment relative to a position of the second segment defines a track plate guide path that extends between the first segment and the second segment such that the track plate guide path has a same shape as the base guide path and is positioned above the base guide path. Alignment of the track plate guide path and the base guide path form a non-linear track, such that the track is configured to slidably receive a portion of a tee.

Abstract: An ambidextrous face guard includes an attachment portion having at least two attachment points. The attachment portion extends from a first end of the ambidextrous face guard toward a second end of the ambidextrous face guard along a slope. The ambidextrous face guard includes a protective portion extending from the attachment portion toward the second end of the ambidextrous face guard along the slope. A line of symmetry extends along at least the attachment portion from the first end of the ambidextrous face guard toward the second end of the ambidextrous face guard such that the line of symmetry defines two symmetric portions of the ambidextrous face guard that each extend along at least a portion of a length of the ambidextrous face guard. The ambidextrous face guard is configured to attach to a right side and a left side of a headgear via the attachment points.

Abstract: An electronic athletic training system includes a first detection device and a second detection device, each of which includes a transmitter, a receiver, one or more visual indicators, a processor, and a computer-readable storage medium. A transmitter of one detection device emits a light beam to the receiver of the other detection device when the transmitter is in proximity to the receiver. A detection device performs one or more actions in response to detecting that the light beam has been broken.

Abstract: A garment includes an impact absorbing pad having a layer of foam material with a body-facing surface, an outer surface that is opposite the body-facing surface, and a set of voids that extend through the layer in a multiple locations. The voids have a repeating pattern of shapes. Each shape includes three void arms having equal lengths that extend from a central vertex point. The impact absorbing pad may also include a second layer overlapping the first layer. The density of the first and second layer may be the same or may be different. The second layer may also have a set of voids overlapping the first set of voids. A covering covers the outer surface of the impact absorbing pad. The impact absorbing pad has a Shore durometer value of about 25 to about 50.

Abstract: An ophthalmic spectacle lens having transmittance properties that block UV and violet light and partially block certain cyan wavelengths to enhance contrast between blue versus green and partially block certain yellow wavelengths to enhance contrast between green versus red, and keep in accordance with the tristimulus values. Adding wavelength-selective organic dyes provides the entire functional attributes of the current invention or improves the contrast-enhancing attributes provided by a glass wafer having functional rare-earth oxides, either of which improve multi-band spectrum that is balanced in blocking UV light, and adding contrast between the primary colors to optimize color-enhancing functions. When using organic dyes for all functional attributes it is possible to integrate these dyes into plastic ophthalmic materials. Some lenses are polarized.

Abstract: A system and process for making an eyeglass temple co-injection molded with a wire core are disclosed. An eyeglass temple is produced by injecting a first shot of temple substrate material into a mold followed by the shot injection of a portion of wire core into the substrate material while it is still molten or semi-molten followed by a second shot injection of additional molten or semi-molten material to completely fill the mold. The first shot of template substrate is provided in a viscosity and amount sufficient to support the wire core without contact by the mold or external support, and the second shot is provided in an amount sufficient to completely fill and pack the mold and lessen shrinkage problems during substrate cooling and hardening. This produces an eyeglass temple in a desired configuration having an entirely encased wire core. Optionally, a second material can then be overmolded onto portions of the temple.
