In some examples, a system includes a head-mounted device, a visor that includes a reflective object that is substantially transparent in a visible light spectrum and embodied at a physical surface of the visor, at least one visor attachment assembly that couples the visor to the head-mounted device; at least one optical sensor; and at least one computing device communicatively coupled to the at least one optical sensor, the at least one computing device comprising a memory and one or more computer processors that: receive, from the optical sensor, an indication of light outside of a visible light spectrum that is reflected from the reflective object; determine, based at least in part on the light outside of a visible light spectrum that is reflected from the reflective object, a position of the visor; and perform, based at least in part on the position of the visor, at least one operation.

A method for use of a convertible band for a cap that includes the steps of: stretching the convertible band around the perimeter of the cap; adjusting the position of the band to fit at the edge of the cap; and positioning an decorative attachment at the front of the cap. The convertible band may be used to cover a user's ears. The band may also be removed and extended to camouflage a user's face. The decorative attachment may also be interchangeable.

A hearing protection apparatus has a pair of assemblies, each assembly including a body, an attachment facility connected to the body and configured to removably receive a lower edge of a hat, a retractable tether extending from the body and having a free end, and an earplug attached to the free end of the retractable tether. The attachment facility may be a clip defining an upwardly open channel. There may be a hat having opposed right and left edge locations each proximate to a wearer's ear, and the attachment facilities may be connected respectively to the right and left edge locations. A retraction actuator may be connected to the body and operable to retract the tethers to a retracted condition in response to actuation of the retraction actuator. There may be separate retraction actuators for each assembly, the retraction actuators being operable independently of each other.

An earmuff for hats, including a holder assembly and a cover assembly. The holder assembly includes a first ring and a second ring coupled together from a bottom portion thereof defining a separated top portion. The cover assembly encloses the holder assembly. The cover assembly is attached to a hat through the holder assembly. The holder assembly is operated to open and close to be clipped to the hat. The cover assembly, when attached to the hat, is an earmuff.

A heat protection garment configured to protect the skin of a wearer may include an ear cover and a forehead cover. The ear cover may include a first surface and a second surface. The first surface may be configured to overlie the skin of the wearer. The second surface may be opposite the first surface. The second surface may include one or more first attachment features. The forehead cover may include a first surface configured to overlie the skin of the wearer and a second surface opposite the first surface. The forehead cover may include one or more second attachment features configured to releasably engage the one or more first attachment features.

The present invention is an earmuff including first and second muff portions with a clip disposed between them. The clip is manipulatable into closed and open positions. When the clip is open, the upper sections of the first and second muff portions are separated. When the clip is closed, the upper sections are together. The earmuffs are designed to cover a human ear and are to be clipped to the headband of a cap by putting the earmuff into the open position, positioning the earmuff around the headband, and positioning the earmuff into the closed position.

A headband, cap, hat, or the like worn by a child, particularly an infant, includes an embedded sound-attenuation system to protect hearing against loud sounds that might startle, awaken, or injure a wearer. Shells formed of a comparatively soft and flexible elastomeric material are secured against the head of a user, each enclosing an ear in an air tight chamber, to close down the transmission paths available to sound waves. The shells are impervious to air, and flexible to conform to the head when secured by the headgear in which the shells are embedded. Each shell is provided with a rim, sufficiently flexible to deform and deflect into complete, sealed contact with the head.

Protective headwear comprising an elliptical crown with an upper end and a lower end, a top with an energy absorbing core layer adjacent thereto and wherein the top is attached to the upper end of the elliptical crown, a brim attached to the lower end of the elliptical crown and wherein a protective cage is coincident with the elliptical crown, and protective structural ribs coplanar with the brim. The protective headwear may comprise a fitting insert. The protective headwear may comprise an engagement strap, and when the engagement strap is pulled, it bends the brim towards a user's head. The protective headwear may comprise a belt with a holder for one or more golf tees and/or pencils.
