  • Patent number: 11717618
    Abstract: Medicinal fluid delivery devices and methods for advancing and retracting needles are disclosed. According to an aspect, a medicinal fluid delivery device includes a tube that defines an interior space that extends between a first and second openings. The device includes a needle including a proximal end and a distal end that substantially align in a first direction. A portion of the distal end is biased to extend in a second direction different than the first direction. A mechanism is attached to the proximal end and configured to position the distal end between a first position and a second position. In the first position, the portion of the distal end is constrained by the interior wall such that is does not extend in the second direction. In the second position, the distal end is not constrained by the interior wall such that it extends in the second direction.

  • Patent number: 7300103
    Abstract: An apparatus for use in conjunction with feeding infants and toddlers. The apparatus is a two-part tool that combines a booster seat along with a spill-proof food tray that is removed and placed onto an adjacent table surface. The booster seat includes a small storage compartment that is located within the booster seat. The spill-proof food tray includes a separate cup holder area along with a catch-all tray that allows food to fall into it rather than onto a floor surface or onto an infant or toddler using the present invention.

  • Patent number: 4317700
    Abstract: A method of fabricating a bubble domain device composite structure on a substrate of depositing a barrier layer of a suitable polymeric dielectric material on the substrate; subsequently depositing a layer of electrically conductive material thereover; subsequently depositing a spacer layer of a liquid polymeric dielectric material over the conductive layer; processing the spacer layer so that the surface of the spacer layer is substantially planar; and subsequently depositing a layer of a magnetically operative material over the spacer layer.
