A push-in earplug is provided. The push-in earplug comprises an elongate core comprising a core material. The push-in earplug also comprises an outer layer comprising a foam material, the outer layer covering at least a portion of an outer surface of the elongate core. The push-in earplug also comprises a channel extending through the elongate core from a first end of the elongate core to the second end of the elongate core.

An over-the-ear hearing assessment device and a method for evaluating the performance of over-the-ear hearing devices are described. An exemplary over-the-ear hearing assessment device includes an ear cup defining an interior volume and positionable at least partially over the ear of a user. The ear cup includes a shell, a cushion, and an acoustic port extending from an exterior to the interior volume of the ear cup. The acoustic port is sealably engagable with a microphone.

An earplug assembly and method of forming the same is described. The method includes uniaxially stretching a cord formed of copolymer including ethylene segments and vinyl acetate segments to form a cold-drawn cord. The cold drawn cord has an elongation to break of 250% or less. The method then includes fixing the cold drawn cord to an earplug.

A cooking grid assembly includes a frame having first and second frame portions. The first and second frame portions each have one of a plurality of notches and a plurality of holes formed therein. A plurality of rods have first and second ends, such that the first end of each rod is disposed in one of the notches and holes of the first frame portion. The second end of each rod is disposed in one of the notches and holes of the second frame portion. A locking bar is removably attached to one of the first and second frame portions. The locking bar is movable between a closed position wherein the rods are retained in the one of the notches and holes, and an open position wherein the rods may be inserted and removed from the one of the notches and holes. An extension member is provided that is fixed to and outwardly movable relative to the frame to provide support to the frame. The extension member is movable between a storage position, an extended position, and a plurality of positions intermediate of the storage position and the extended position.

A golf club reminder method includes providing a golf bag that has an upper edge. A plurality of golf clubs is positioned in the golf bag. A post has a bottom end and a top end. A flag is attached to the post adjacent to the top end of the post. The flag has indicia thereon indicating a reminder to verify all golf clubs are accounted for. A coupler is attached to the bottom end of the post. The post is attached to the golf bag adjacent to the upper edge with the coupler and the post extended upwardly from the golf bag. The post is thereby attached to the golf bag during a round of golf.

A buoy drilling anchoring system including a retrievable buoy anchoring drilling device and at least one anchorable marker buoy assembly anchorable into the earth's surface underwater. The retrievable buoy anchoring drilling device is adapted to anchor in the earth's surface underwater at least one anchorable marker buoy assembly having an earth penetratable anchor and is retrievable from underwater after the anchorable marker buoy assembly is anchored for subsequent use thereof. Thereby, a single retrievable buoy anchoring drilling device can be used to anchor a plurality of anchorable marker buoy assemblies such as used to mark the underwater locations for placement of cables or pipelines such as without limitation, a gas pipeline and an oil pipeline.

The present invention relates to a breeding box that temporizes aggression of strong beaked exotic birds. In one aspect, the assembled box comprises (i) a central section having a pair of arms defining non-parallel axes of symmetry and a nesting arm extending from the pair of arms. The pair of arms in association with the nesting arm define a junction point between them. Each of the pair of arms also includes a normally open external passageway to permit external entry and egress of birds relative to the central section. The assembled box also includes (ii) a baffle positioned adjacent to the junction point of the arms. The baffle is in attaching contact with the central section whereby direct passage between the pair of arms bypassing the nesting arm is prevented, and wherein a sitting female within the nesting arm is provided with an escape option whereby male aggression can be temporized without disruption of the breeding cycle. Note that the passageway defined within the pair of arms is adjacent to anteroom regions connected to a flight cage; that the nesting arm provides the nest for the female; and that the purpose of the baffle is to limit direct passage of the male from one of the pair of arms to the other (bypassing the nesting arm), as when the female is escaping from the nest. A method of assembly is also described.

Breeding box construction and method for temporizing male aggression

The present invention relates to a breeding box that temporizes aggression of strong beaked exotic birds. In one aspect, the assembled box comprises a Tee-shaped central section having a pair of parallel arms defining a pair of spaced apart anteroom regions each connected by an opening to flight cage. Connected to the pair of parallel arms is a nesting arm for the female normal to the pair of arms and positioned below the latter. At the junction of three arms is a Tee-shaped baffle having a planar and a vertical element that limits direct passage of the male from parallel arm to parallel arm (bypassing the nesting arm), as when the female is escaping from the nest. That is, the vertical element forms a solid wall defining a vertical plane intersecting the nesting arm, while the parallel element limits passage height for the male that only permits him to crawl down into the nesting arm with his head exposed via a ladder. In addition, the planar element is long enough of overhang the anteroom regions to provide reduced crawl space that also limits the speed that the male can tranverse the same. Thus when the male first enters the breeding box via one of the openings to the anteroom region, the female has ample time to escape via the unoccupied anteroom region and then through the opening to the flight cage. A method of use is also described.
