The pulldown panel net demarcates the middle bed from the right angle bed. The pulldown panel net further has an elastic cord attached to the right lower frame horizontal member.

Abstract: A swing attachment comprising a right suspension line and a left suspension line. A right swing seat connector and a left swing seat connector. The right swing seat connector is connected to the right suspension line, and the left swing seat connector is connected to the left suspension line. The right swing seat connector is connected to the swing seat. The left swing seat connector is connected to the swing seat. The right suspension line and the left suspension line suspend the swing seat. A left sleeve is mounted to the left suspension line, and the right sleeve is mounted to the right suspension line. The left sleeve is mounted above the left swing seat connector. The right sleeve is mounted above the right swing seat connector.

Abstract: A strap spring trampoline includes a trampoline frame having an upper horizontal trampoline frame and a lower horizontal trampoline frame. A trampoline bed is extended across the upper horizontal trampoline frame. A strap connection is formed on the trampoline bed that connects the trampoline bed to a tension strap. A spring is connected to the tension strap and the lower horizontal trampoline frame. The spring is preferably helical. The trampoline leg rigidly connects between the upper horizontal trampoline frame and the lower horizontal trampoline frame. The upper horizontal trampoline frame has a horizontal extension, and the horizontal extension further includes a flat section. A spool sleeve fits over the upper horizontal trampoline frame, and a tension strap rides over the spool sleeve when the tension strap moves over the upper horizontal trampoline frame. A right collar and a left collar fit together and retain the spool sleeve.

Abstract: An accessory structure trampoline has a main trampoline with a main trampoline bed, main trampoline springs, and a main trampoline spring cover. The main trampoline includes trampoline legs having a first vertical leg section and a second vertical leg section. An accessory structure is pivotally mounted to the first vertical leg section and the second vertical leg section. The accessory structure folds from a deployed position to a stowed position. The accessory structure can be a small trampoline that is smaller than the main trampoline. The small trampoline folds from a deployed position to a stowed position. The small trampoline has a fold-down handlebar and folding legs, and the fold-down handlebar folds from a deployed position to a stowed position. The accessory structure can also be a hammock swing. The hammock swing folds from a deployed position to a stowed position.

Abstract: A modular inflatable obstacle course includes a frame unit. The frame unit is configured to be placed adjacent to a second frame unit in a sequence with a first frame unit and a last frame unit. A constant air inflatable portion is configured to be placed adjacent to a second constant air inflatable portion with a first constant air inflatable portion and a last constant air inflatable portion. The constant air inflatable portion fits over the frame unit and is preferably strapped to the frame unit. The constant air inflatable portion is attached to the frame unit to support the constant air inflatable portion. The constant air inflatable portion covers a portion of the frame unit. An air connection such as a fabric tube is preferably formed between the frame unit and the constant air inflatable portion.

Abstract: A trampoline includes a trampoline frame with trampoline legs supporting the trampoline frame above a ground. Trampoline springs connect to the trampoline frame. A trampoline bed is connected to the trampoline springs. The trampoline bed is extended across the trampoline frame. A trampoline enclosure has at least one enclosure pole supporting an enclosure net. A pulley system is mounted to the enclosure pole and the pulley system includes a pulley mounted to a pulley line. The pulley line connects to an enclosure top support. The enclosure net is connected to the enclosure top support. Optionally, the trampoline also has a free end of the pulley line. The free end of the pulley line extends away from the pulley to be accessible to a user.

Abstract: A trampoline includes a trampoline frame including a trampoline frame ring supported by a trampoline frame. A trampoline bed is supported across the trampoline frame. The trampoline frame is foldable. Enclosure poles are oriented in a vertical orientation when the enclosure poles are in a deployed position. One or more hinge joints connect the enclosure poles to the trampoline frame. The enclosure poles are mounted to the trampoline frame ring at the hinge joints. The enclosure poles fold inward to a horizontal position when the enclosure poles fold to a folded position. The enclosure poles may overlap each other when folding to the folded position.

Abstract: A spring enclosure trampoline has a trampoline bed connected across a horizontal frame member. Trampoline legs supporting the horizontal frame member above a ground surface.

Abstract: The present invention comprises a method for generating a pseudo-CT image volume from multiple MRI scans through determining and then applying multi-variable polynomial mapping functions. An exemplary example extracts intensity values of voxels in images from acquired multiple MRI scans and CT scan from a plurality of training subjects to determine a multi-variable high-degree polynomial function for each of three regions, which is then applied to voxels in corresponding regions from images of multiple MRI scans of the target subject to generate the pseudo-CT image volume.
