Abstract: A squirrel-proof post is composed of a post, supporting a bird feeder or bird house, an annular sleeve, a set of springs, and a means of securing the springs to both the platform supporting the bird feeder or house and to the sleeve. The set of springs will be naturally somewhat elongated due to the weight of the sleeve. When the squirrel climbs up the post and onto the sleeve or else jumps from the ground onto the sleeve, the additional weight will cause the sleeve to begin to slide down the post at a rate approximating free fall. This sudden and rapid acceleration induces the squirrel to immediately jump off the sleeve, returning to the ground unharmed. The reduction in weight acting in opposition to the restoring force of the springs will rapidly result in the return of the sleeve toward its equilibrium position.

Abstract: A packaging system including both methods and specific types of packaging addresses the need for a fully recoverable, reduced-volume packaging of compressible items. The system may involve initially compressing the item through folding and the like and wrapping the item for insertion into a bag or other flexible impermeable encasing. This bag may then be compressed externally or through evacuation and sealed so that the flexible impermeable encasing acts in conjunction the ambient pressure environment to hold the item in a fully compressed state. For ease of sealing the bag the entire package may be subjected to lower pressures and then sealed. In this manner the item is sealed prior to compression. In order to achieve full recovery of the item the compressible item may be constructed of an open-cell foam having a density at least greater than 1.2 pounds per cubic foot.
