Abstract: A method of integrating a cryptographic digital asset into a digital software application, includes receiving a digital asset identification (ID) code, the digital asset ID code existing together with a unique owner ID code on a distributed blockchain ledger. The digital asset ID code represents the cryptographic digital asset, and the cryptographic digital asset comprises a plurality of attributes. A virtual object is then represented on the display via the digital software application. The virtual object has an appearance that is based on the plurality of attributes of the cryptographic digital asset, and the virtual object includes a plurality of object attributes. The method further includes modifying at least one of the object attributes according to an aspect of the digital software application or interaction between the character avatar and the virtual object and representing a modified virtual object on the display via the digital software application.

Abstract: A stroller seat has a seat bottom with a calf support pivotally connected thereto and pivotable between a lowered position and a raised position. A positioning mechanism is coupled to the calf support and movable between an engaged arrangement and a released arrangement. The positioning mechanism, when in the engaged arrangement, retains the calf support in a position selectable from among at least the lowered position and raised position. A release actuator on the calf support is coupled to the positioning mechanism. The release actuator moves the positioning mechanism to the released arrangement. The positioning mechanism, whether in the engaged or released arrangement, allows the calf support to move in the direction of the raised position. The positioning mechanism, when in the engaged arrangement, prevents the calf support being moved in the direction of the lowered position. The positioning mechanism, when in the released arrangement, permits the calf support to move toward the lowered position.

Abstract: A fold joint for a stroller has a first latch part fixed to a first frame element and a second latch part fixed to a second frame element. The latch parts are pivotable relative to one another about a pivot axis between an in-use orientation and a folded orientation. A latch shuttle is movable between a latched position locking the latch parts in the in-use orientation and an unlatched position unlocking the latch parts. A latch pin is carried by the latch shuttle. A track on the first latch part has a fold portion and a latch portion. A slot on the second latch part aligns with the latch portion in the in-use orientation. The latch pin is captured within the track and slot. When the latch shuttle is moved to the unlatched position, the latch pin is moved along the latch portion to the fold portion of the track. When the latch parts are pivoted toward the folded orientation, the latch pin moves along the fold portion of the track.

Abstract: A stroller fold joint has first and second joint parts. The first part has a hosel coupled to a hub body with a circumferential surface and a pivot axis. The second part has a connector coupled to two plates. The hub body is between the plates and the two joint parts pivot about the pivot axis between a folded and an unfolded orientation. A tunnel through the hub body is perpendicular to the pivot axis. A shuttle slides within the tunnel and has latch end and an actuator end. The latch end is adjacent the hub body's circumferential surface at one tunnel end and the actuator end extends into the hosel. The shuttle is not exposed and is covered when the fold joint is in the folded or unfolded orientations and when moving therebetween.

Abstract: A stroller wheel assembly has a wheel mount with an interior cavity and defining a generally vertical housing axis. An axle is carried by the wheel mount and a wheel is carried on the axle and rotatable about a rolling axis oriented perpendicular to the housing axis. A leg of a stroller frame has an end section coupled to the wheel mount. A suspension spring has one end borne against a spring stop on the wheel mount within the interior cavity and an opposite end borne against a fixed stop. The spring resiliently supports the wheel mount for movement against a bias force and by the bias force of the spring relative to the leg along the housing axis. The wheel assembly can also be capable of swiveling about the housing axis relative to the leg.
