Abstract: Protective headgear that is wearable on a head of a user and may be configured to provide impact protection and contaminant protection. The protective headgear may comprise a helmet configured to protect the user's head against impacts and a contaminant blocker configured to protect against contaminants (e.g., infectants), such as pathogens (e.g., viruses, bacteria, or other microorganisms) or other biohazards, chemical hazards, or other hazardous substances, transmittable to or from the user (e.g. as part of spatter, an aerosol, or other droplets). The helmet and the contaminant blocker may be configured to connect or otherwise interact with one another to be usable together. This may facilitate their use to enhance protection of the user and/or an environment of the user, while maintaining performance of the user, including by providing breathability, being spatter proof, ensuring proper vision, being antifogging, being customizable, and/or having other desirable attributes.

Abstract: A swaddling device is described. The swaddling device includes a sack configured to substantially enclose a baby. The sack includes sleeves and an attached wrap configured to swaddle the baby. The swaddling device at least partially restricts movement of the baby and thereby suppresses the Moro Reflex, while also snugly enveloping the torso of the baby and thereby providing constant moderate pressure thereto. The wrap is sufficiently narrow so as not to restrict movement of the baby's hips and knees, while also providing access to the lower portion of the baby for diaper changes. Some versions of the device include sleeves having at their ends foldover mitten cuffs or other selectively openable mechanism. The cuffs allow a caregiver to expose the hand or hands of the baby so as to provide skin-to-skin contact. Alternatively, the caregiver can close the cuffs if scratching is a concern.

Abstract: A comfortable construction helmet easy to assembly and adjust is revealed.

Abstract: As described above, one or more aspects of the present disclosure provide articles having structural color, and methods of making articles having structural color. The present disclosure provides for articles that exhibit structural colors through the use of an optical element, where structural colors are visible colors produced, at least in part, through optical effects. The optical element (e.g., a single layer reflector, a single layer filter, a multilayer reflector or a multilayer filter) can include the reflective layer(s), constituent layers, and an optional textured surface. The optical element has a minimum percent reflectance in a wavelength range within the wavelength range of about 380 to 625 nanometers. The optical element imparts a structural color that corresponds substantially to the range of wavelength range.

Abstract: A shock absorbing system for force attenuation, impact modification or reduction, employs an envelope having a chamber containing a first working fluid, the envelope deformable in response to the impulse to attenuate impact force. A plurality of resilient supplemental absorber elements dispersed within the chamber. The plurality of resilient supplemental absorber elements are deformable in response to the force to assist in attenuating impact force and provide additional resilient restoring force to return the envelope to a pre-impact shape. In alternative implementations, a unitary cell for energy dissipation employs an envelope having a chamber containing a first working fluid and an inner element contained within the chamber and having an inner chamber containing a second working fluid.

Abstract: A securing device that allows adjustable securing of a face mask, face shield or goggles to a wearer's head is formed from a first portion having a strap, a first end with a securing button and a connecting element, and a second portion having a strap, a first end with a securing button and a connecting receptacle for interacting with the connecting element to connect the two straps together. The securing buttons are formed from a top plate connected to a bottom plate via a connecting leg having a cross section with an acute angle. The bottom plate has slits extending from an outer edge to the connecting leg on both sides of the acute angle, such that a cord is securable to the securing button by inserting the cord into one of the slits, wrapping the cord around the acute angle of the connecting leg and exiting from the other of the slits.

Abstract: The technology described herein relates to breathable, vented, and insulating garments. More particularly, the technology described herein relates to garments with chambers to retain an insulating fill material. Openings along seams between the insulating chambers may achieve evaporative moisture or air transfer from the inside (proximal to the body of a wearer) of the garment to the outside environment. In an aspect, the garments comprise one or more insulated zones provided with one or more vented-insulation sections provided at locations on the garment configured to align with one or more areas of a wearer's body that are more sensitive to environmental conditions (e.g. temperature) and/or are prone to faster heat loss.

Abstract: A ventilation apparatus for an article of footwear has a hollow air pump chamber, one or more one-way air valves positioned through the top wall of the air pump chamber, and an air intake channel with a one-way valve coupled through an opening into the air pump chamber. Action of stepping down on the air pump chamber deforms the walls and increases pressure in the air pump chamber, and forces air out of the air pump chamber through the one or more one-way air valves positioned through the top wall of the air pump chamber, and action of lifting weight off the air pump chamber causes the deformed walls to return toward original form, decreasing pressure in the air pump chamber and drawing air in through the air intake channel.

Abstract: Soles for articles of footwear including a mechanically anisotropic three-dimensional mesh. The mechanically anisotropic three-dimensional mesh can include one or more mechanically anisotropic regions with a first lattice shear modulus measured in a first direction and a second lattice shear modulus measured in a second direction opposite to or orthogonal to the first direction. The first and second lattice shear moduli are different to provide the three-dimensional mesh with mechanically anisotropic properties. The mechanically anisotropic three-dimensional mesh can be three-dimensionally printed.
