Abstract: The present invention is a hood or cover for golf bags, which features pneumatic, air-filled tubes and/or stiffeners, used as a frame or skeleton, to produce a finite, yet compliant physical shape. The inventive rain hood utilizes a hinged top to accommodate the full range of club sizes and yet make removal and replacement quick, easy and positive. The hood or cover also shields the remaining clubs while removing or replacing any one club. A universal attachment system accommodates almost all golf bags commonly used today. The attachment mechanism is a one-step cinch system which is infinitely adjustable from the smallest to the largest of currently-used golf bags. Once attached, the rain hood inflates quickly to its rigid state with either a built-in hand pump or an auxiliary pressurized hand-held inflator.

Abstract: Plant germplasm is transformed with foreign DNA by introducing the DNA into pollen grains by a technique such as electroporation, mating ova of the desired plant line with the transformed pollen, and selecting for the transformed germplasm. The germinating pollen, resultant seed, and the progeny can each be screened for expression of the foreign gene. The transformed pollen can be used as a vector for introducing the foreign DNA into plant lines of similar or dissimilar origin, including both monocots and dicots.

The acquisition phases include a period during which the beacon scans an uncertainty cone associated with the node spacecraft. This scanning period is reduced for second and subseqeunt acquisitions by using the first and subsequently acquired communication links to provide a more accurate estimate of the angular attitude of the node spacecraft, thus reducing the extent of the uncertainty cone.
