Abstract: A collapsible, self-expanding polyhedron comprises a plurality of side members each connected with an elastic band that is sized to urge each side wall of adjacent side members together to form an expanded configuration. When the polyhedron is compressed on two opposing side members, which causes the other side members to separate into a collapsed configuration, the elastic band expands to a maximum length with maximum tension. Once the compression is released, the at least one elastic band retracts back to a minimum length and urges the side members back into the expanded configuration.

Abstract: A rope arrest-and-release device comprising a cam block assembly and a housing with front vertical rollers situated on either side of the housing, rear vertical rollers situated directly behind the front vertical rollers, and a pair of horizontal rollers situated to the interior of the front and rear vertical rollers on either side of the housing. The cam block assembly includes a cam block and a cam that rotates upward and downward via a spring. Each front vertical roller is configured to rotate forward to allow a rope to be inserted between the cam and the inside ceiling of the housing. The cam block assembly fits into an internal recess in the housing and is removable and reversible. The invention include a means for securing the device to a utility pole and for locking the cam in a downward (open) position.

Abstract: This container lid fits onto existing insulated cups. It has a refillable and sealable reservoir and in the preferred embodiment includes a top opening to receive substances and a bottom opening to release substances into a container. The release of substances into the beverage container is controlled and is measured before release. A preferred double piston and button combination interact with a narrow section of the reservoir to dispense only a portion of the contents from the reservoir into the container. The released portion is carefully metered within the narrow channel when the double piston alternately seals a first opening and a second opening of the narrow channel. The reservoir serves to store the unreleased substance until the next time the button is activated to release addition substance into the container.

Abstract: An assembly has a frame with two ends and two rails with a drop section generally centered, a base plate spanning the rails at the drop sections, a turn table upon the base plate, a pivot tray upon the turn table, linkages upon the pivot tray, sections operatively connected to the linkages, spring panels upon the sections, and a mattress upon the section. Senior citizens, patients, and disabled persons find difficulty to enter and to climb out of bed and may frequently require assistance. When this problem occurs, others must assist a person and the assistance varies depending on the person's size, weight and degree of mobility. The present invention adapts easily to most standard bed frames and allows a patient to rotate clockwise or counterclockwise and then to a sitting position.

Abstract: An outdoor amusement rocking device having a frame and a support member that together form a curvature saddle-shaped play structure.

Abstract: A system and method is provided for a toy race track. Preferred embodiments of the present invention operate in conjunction with a vehicle affixed to a track, wherein the track is supported in relation to at least one fixed surface via a plurality of support structures. In one embodiment, the track comprises a plurality of flexible sections, allowing a user to construct a track resembling a rollercoaster, having steep curves, upside-down portions, etc. In one embodiment, the vehicle includes a plurality rollers that can be used to both affix the vehicle to the track and propel the vehicle along the track. By affixing the vehicle to the track, the vehicle is prevented from leaving the track during extreme situations (e.g., steep curves, upside-down portions, etc.).

Abstract: This container lid fits onto existing insulated cups. It has a refillable and sealable reservoir with a top opening to receive substances and a bottom opening to release substances into a container. The release of substances is controlled and measured before release. A double piston and button combination interact with a narrow section of the reservoir to dispense only a portion of the contents from the reservoir into the container. The released portion is carefully metered within the narrow channel when the double piston alternately seals a first opening and a second opening of the narrow channel. The reservoir serves to store the unreleased substance until the next time the button is activated to release addition substance into the container.

Abstract: An apparatus for creating spin art comprised of a base assembly, spinning platform and upper assembly. The base assembly includes a central housing, and the upper assembly includes a circular paint wall surrounding a paint container column. The paint container column is positioned in the center of the spinning platform and made up of individual paint container modules that are configured to be stacked vertically on top of one another. The invention also includes a gear drive assembly that is driven by either a manually activated plunger or an electric motor.

Abstract: A device for stabilizing impaled objects in the human body, the device having a first and a second component each of which is comprised of a generally T-shaped support plate that is adhered to a generally T-shaped foam pad. Each component has a lower section and a base section. The support plate comprises a bend line between the tower section and the base section and a channel along each outside edge of that portion of the support, plate that comprises the tower section. The foam pad comprises a slit along each, outside edge of that portion of the foam pad that comprises the tower section. First and second fastening straps are bonded between the support plates and foam pads.
