  • Patent number: 5850789
    Abstract: An apparatus and method for mounting a plurality of plates onto a carrier sheet includes a table mounted on a stationary base, each plate having a first and a second registration mark thereon. A first camera assembly is moveably attached to a support adjacent the table and is connected to a first video monitor for viewing the first registration marks. A second video camera is moveably attached to the support adjacent the table and is connected to a second video monitor for viewing the second registration marks. Linear actuators are connected to the first and the second camera assemblies and to the table for independently moving each camera assembly relative to the table. A motion controller is connected to the linear actuators for sending moving signals thereto, and generates at least two moving signals corresponding to the two registration marks for each plate.

  • Patent number: 5709000
    Abstract: A common way for an adult to carry a baby is to cradle the baby in both arms, so that the baby's head is resting on one of the adult's shoulders. However, the baby may drool onto the adult. Also, thin adults with bony shoulders may cause discomfort to the baby's head. Such problems are solved by a combination baby pillow and drool guard that includes a shell stuffed with soft batting. A hole is arranged on the pad, so that it may be worn around the neck of the adult. The pad covers the shoulders and upper chest area of the adult to cushion the baby's head, and to protect the adult's clothing from the baby's drool. In a first embodiment, a pair of straps connect the opposite ends of the pad together when worn. In a second embodiment, a releasable joint extends between the hole and an edge of the pad for facilitating donning and removal. In a third embodiment, the pad includes a pair of wings extending from the sides for providing extra coverage on the adult's shoulders.
