  • Patent number: 8256041
    Abstract: An infant or baby crib is provided that eliminates the vertical slotted members normally present on the sidewalls and end-walls, and replaces these with a planar fabric, leather or canvas member that spans each sidewall or end wall, respectively. The planar member is generally flexible to prevent fixed pinch points between rigid beams or slats that have now been identified as creating a strangulation hazard. Canvas or leather side panels form a large central orifice in which a clear plastic panel forms a viewing window, thereby allowing the infant to see through the sidewall.

  • Patent number: 6012746
    Abstract: An apparatus to improve traction conditions for motor vehicles under winter time driving conditions is disclosed. The invention comprises a sand storage reservoir and delivery system that supplies sand to each tire of a motor vehicle to aid in traction when driving in icy or snowy conditions found in wintertime driving. The sand reservoir provides sand to a plenum through four distinct sand compartments which dispense individual slugs of sand to a series of discs, connected via a cable, which move the sand through a delivery pipe to any of the four motor vehicle tires, as selected by application levers on the sand reservoir. The reservoir and associated controls are located inside the passenger compartment of the motor vehicle with the delivery tubes located on the undercarriage of the motor vehicle.
