  • Patent number: 11534007
    Abstract: Crib liners configured to reduce entanglement of an infant's appendages between vertical slats of a crib, and methods for fabricating such crib liners are described. The crib liner includes a bottom layer dimensioned to cover a lower surface of a crib and a side panel formed of a breathable material extending generally perpendicular from the bottom layer. The side panel is continuous in construction such that if forms a closed circuit around the bottom layer and is configured to form a closed circuit around the perimeter of the crib and extend beyond the top surface of the crib railing. Stays are attached at intervals along an edge of the side panel. The stays are configured to hold the crib liner in place relative to the crib.

  • Patent number: 11528965
    Abstract: A buckle assembly with a disengagement prevention device and a method for using the same is disclosed. The buckle assembly has a first buckle member having a first strap holding structure configured to adjustably affix the first buckle member to a first strap segment. A second buckle member is configured to couple with the first buckle member, the second buckle member having a second strap holding structure configured to affix the second buckle member to a second strap segment. A disengagement prevention device is configured for engagement with the first and second buckle members to maintain the first and second buckle members in a coupled state under conditions where the first and second buckle members are not properly engaged or the engagement between the first and second buckle members is accidentally released.

  • Publication number: 20220361687
    Abstract: An infant support device for holding an infant. A fabric panel is taut between two or more anchor points. The anchor points may be disposed on a support frame or another structure capable of supporting the fabric panel and a weight of an infant. The fabric panel contains an aperture. A mesh insert is affixed to the fabric panel at the contour of the aperture. The mesh insert has a lower stiffness than the fabric panel. The mesh insert contains a plurality of holes sized to permit air to flow therethrough while preventing an infant's limbs and appendages from entering therein. Responsive to an infant being placed onto the mesh insert, the mesh insert elastically deforms thereby transitioning into a stretched configuration, in which the mesh insert urges the infant's spine into a convex curve.

  • Patent number: 6545445
    Abstract: A multiple battery system and method for starting internal combustion engines, such as on a boat or vehicle, and for powering auxiliary functions that operate primarily when the engine is not running is disclosed. A first battery is used for starting the engine. A second battery is used to power the auxiliary features associated with the boat or vehicle primarily when the engine is not running. The first battery, referred to as the starter battery, is a high output battery that produces high bursts of energy for limited amounts of time. The second battery, referred to as the auxiliary battery, has a low power output over a fairly long period of time, is capable of being completely drained without harming the battery, and is capable of being fully recharged. The starter battery and the auxiliary battery are connected by a circuit that has an on/off switch controlled by an electronics control module. The auxiliary battery is always on line in the circuit.
