Landing pads for a drone. One of the landing pads can include a landing station configured to mount onto a non-horizontal surface; a landing area i) connected to the landing station and ii) with a first surface configured to receive a second surface of a landing gear of a drone; a fixed member i) connected to the landing station and that ii) includes a third surface near an end of the landing area and iii) is configured to contact an end of the landing gear of the drone; a moveable member i) connected to the landing station and ii) that is configured to a) move the landing gear across the first surface of the landing area and b) secure the landing gear of the drone substantially in place between the first surface of the landing area and the third surface of the fixed member.

Headwear includes a crown of planar fabric panels sewn together in-plane and a brim. The headwear includes a size adjuster of a strip of fabric provided on the lower portion of the crown, around the entire circumference or part of the circumference of the crown.

The size adjuster includes, in a space defined by a casing formed by the strip of fabric, a shape-changing component that extends in the circumferential direction of the crown by a predetermined length by heat of a predetermined temperature or higher. Each of the fabric panels, the strip of fabric, or each of the fabric panels and the strip of fabric has a contour and a mesh formed by cutting fabric on the bias. At least one of the following are sewn together using elastic thread: (1) the fabric panels; (2) the crown and the brim; and (3) the crown and the size adjuster.

Embodiments are disclosed for headwear including a headwear body comprising one or more panels, where at least one panel of the one or more panels is comprised of a three-layer sandwich of material, the three-layer sandwich of material including a first layer, a second layer, and a third layer, the second layer positioned intermediate the first layer and the third layer and comprised of a semi-rigid mesh material.

A ball cap with a concealed opening that allows for a greater variety of hairstyles to be worn while simultaneously retaining the general shape, appearance, and functionality of a typical ball cap. The concealed opening is hidden in a default configuration of the hat, but it can be selectively opened to allow for hair such as a ponytail to pass through. The ball cap can include a protective coating on the sweatband to prevent makeup, sweat, and dirt from soiling the sweatband.

One variation of a method for fabricating a dermal heatsink includes: fabricating a substrate defining an interior surface, an exterior surface opposite the interior surface, and an open network of pores extending between the interior surface and the exterior surface; activating surfaces of the substrate and walls of the open network of pores; applying a coating over the substrate to form a heatsink, the coating comprising a porous, hydrophilic material and defining a void network; removing an excess of the coating from the substrate to clear blockages within the open network of pores by the coating; hydrating the heatsink during a curing period; heating the heatsink during the curing period to increase porosity of the coating applied over surfaces of the substrate; and rinsing the heatsink with an acid to decarbonate the coating along walls of the open network of pores in the substrate.

Hat with improved comfort. One example is a hat comprising: a crown; a brim coupled to the crown and extending away from the crown; a notch defined by the crown, the notch defining a first intersection and second intersection; an adjustable closure comprising a snap member and eyelet member, the snap member defining an inside surface and a proximal end coupled to the crown at the first intersection, and the eyelet member defining a proximal end coupled to the crown at the second intersection; and a comfort material coupled to the inside surface of the snap member, the comfort material extends from the first intersection of the snap member to a distal end of the snap member.

A removable cooling apparatus for a hat spaces a headband of the hat away from a wearer's head, creating an air gap that allows air flow over the wearer's head. A removable cooling apparatus uses coupling structures to hold the removable cooling apparatus in place against the headband. The removable cooling apparatus can be removed completely from the hat when not needed or for cleaning, leaving the hat in an unaltered state. A removable cooling apparatus may use a thin flexible strip to keep the headband of the hat from falling open into the air gap created by the removable cooling apparatus. The removable cooling apparatus use compressible pads to space the headband away from the wearer's head. The contact location of the compressible pads with the wearer's head can be easily adjusted by the wearer.
