    摘要: A roof opening structure for a roof includes support members supported by the roof and a frame supported by the support members. An uplift kit secures the frame to the roof to prevent lifting of the frame with respect to the roof. While preventing lifting of the frame from the roof, the uplift kit permits horizontal movement of the frame on the roof. The horizontal movement could occur due to temperature expansion/contraction of the roof.

    摘要: The present invention is a method and apparatus for establishing a common datum georeferenced position of the phase centers of the antennas used by a system. The system includes a GPS receiver and an auxiliary transmitter. An auxiliary antenna of the auxiliary transmitter is co-located with a GPS antenna of the GPS receiver. The auxiliary antenna is at a known spatial relationship with the GPS antenna. An auxiliary position of the auxiliary antenna is determined based on the known spatial relationship.

    摘要: A DECORATIVE PUPPET HAVING A COLLAPSIBLE FRONT AND REAR PANEL. THE PANELS ARE CONNECTED TOGETHER SO THAT THE PUPPET HAS A PAIR OF STABLE POSITIONS. THE FRONT PANEL ALSO INCLUDES PORTIONS WHICH ARE COVERED IN A FIRST OF THE STABLE POSITIONS. THE PUPPET IS ELEVATED IN HEIGHT WHEN PLACED IN THE OTHER OF THE STABLE POSITIONS. THE COVERED PORTIONS ARE EXPOSED WHEN THE PUPPET IS IN THE ELEVATED POSITION.
