Abstract: An environment-transforming system transforms a user's environmental information in ways that allow the user to better perceive her environment. For example, the system transforms some aspects of a visual scene into a sound space for a visually impaired user. Once the user learns to interpret the sound space, she avoids walking into an object because a sound cue tells her that the object is in her near environment and roughly where it is. Various types of transformations are possible depending upon the user's needs and preferences. As all people are different, each user has a personalized profile that directs the transformation process. More generally, the environment to be transformed may include aspects of artificial or enhanced reality. The transformed environmental information can be presented to the user in a number of ways, such as in haptic feedback, as directional audio, through oral stimulation, or through modified visual display.

Abstract: A trap for insects such as ants is described which fits over the insect hill or mound and traps both emerging and returning members of the insect community. The trap is provided with a unique cover which prevents winged members of the community from flying out of the trap to establish nests and reproduce elsewhere. Provision is also made in the trap for drainage so that water does not accumulate and destroy the effectiveness of the trap.

Abstract: A retractable goal post device is provided which comprises telescoping upright sections which are retracted when not in use into a casing disposed below ground level with a hinged top cover flush with the surface of the playing field. The top cover can be raised to permit raising and lowering of the goal post but is lowered at other times so as to not interfere with the play on the field. A hydraulic activating device is provided for raising and lowering the goal post and the top cover of the casing. Artificial turf is provided to cover the top cover portion of the casing.
