  • Patent number: 8127715
    Abstract: The present invention relates to a mobile pet bed wherein the top and bottom units of the mobile pet bed are reversibly attached to each other. When the top unit is removed from the bottom unit the mobile pet bed functions similarly to a traditional pet bed. When the top unit is attached to the bottom unit the mobile pet bed functions as a pet carrier. Additionally, the top unit of the mobile pet bed has a door portion that can be opened and closed to permit pet ingress and egress as well as permitting easy loading of the mobile pet bed with the animal without necessitating the removal of the top unit from the bottom unit.

  • Publication number: 20120037931
    Abstract: Methods of packaging a semiconductor light emitting device include dispensing a first quantity of encapsulant material into a cavity including the light emitting device. The first quantity of encapsulant material in the cavity is treated to form a hardened upper surface thereof having a shape. A luminescent conversion element is provided on the upper surface of the treated first quantity of encapsulant material. The luminescent conversion element includes a wavelength conversion material and has a thickness at a middle region of the cavity greater than proximate a sidewall of the cavity.
