Abstract: A toy is disclosed. The toy includes a toy building block, a snap-together electronic toy, and an adapter. The toy building block includes a first building block mating member. The snap-together electronic toy includes a first snap-fitting member. The adapter is configured to connect the toy building block to the snap-together electronic toy. The adapter includes a second building block mating member which is configured to mate with the first building block mating member of the toy building block, and a second snap-fitting member which is configured to mate with the first snap-fitting member of the snap-together electronic toy.

Abstract: A housing used to combine a standard electronic prototype system and a modular block system with stackable connectors to achieve a design system that allows for safe assembly of circuits of a more complex nature than can be achieved by either system alone.

Abstract: A battery holder containing positive temperature coefficient (PTC) resetable fuse to electronically limit the maximum current that can be drawn from circuits built using reusable electronic component housings. A power supply with similar housing to reusable battery holders, also designed to limit maximum current and perform electrically equivalent to two or more battery holders. A reusable electronic housing with means for attaching any two leaded electronic component for insertion into quick connect assembly system. This housing also contains a positive temperature coefficient (PTC) resetable fuse to electroniclly limit the maximum current that can be sent through the attached two leaded component.

Abstract: The integrity, connection and location of cable wire termination extending between two different points is checked for shorts between wires and open wires. The actual remote termination plug configuration can be mapped from testing end to determine remote plug wiring. The actual location of the remote terminated end is identified either by a visual indicator, a electronically recorded message made by operator at time of cable termination, or both.

Abstract: Enjoyable propulsion toys can be readily propelled by special magnetic impulse reaction systems. The toys include attractive resilient projectiles which are constructed of foam rubber in order to be safe for children. The projectiles are propelled from base units which contain circuitry for the magnetic impulse reaction systems. Preferably, the circuitry includes a flash tube for emitting a flash of light when the projectile is propelled. Desirably, the circuitry also includes an acoustical generator to generate propulsion sounds when the projectile is propelled. The projectile can be in the form of a: toy rocket, toy airplane, toy glider, toy wheeled vehicle, or toy bullet.

Abstract: An attractive magnetic dart system provides exciting games which are fun, educational and entertaining. Advantageously, the user-friendly system utilizes safe magnetic darts which will not harm people or damage walls, furniture, etc. surrounding the target. The safe magnetic darts each have a magnetic head with a flat front face, which is preferably much larger than the body of the dart. In the preferred form, the magnetic darts have long fins fabricated of a sponge-like material, such as urethane, to. enhance and better stabilize the flight of the darts. Desirably, the magnetic heads of the darts are heavier than the combined weight of the bodies and fins of the darts to further enhance magnetic contact of the magnetic head of the dart to the target. The magnetic dart preferably has optical viewing portions to view the target when aiming the dart and to view the portion of the target that the dart has struck.

Abstract: A user-friendly process and fail safe system instantaneously identifies, locates, and help retrieve products and their contents in drawers, shelves, rooms, offices, stores, warehouses, etc. The efficient process and economical system is particularly useful to quickly and accurately identify, locate and help retrieve: computer discs, compact discs, software diskettes, video tapes, audio tapes, and their cases; books; files; boxes, cartons, storage bins, and other containers. In the reliable process and low power system, an electrically conductive label is placed on each product. Each label is easily coded to uniquely specify the product or its contents and storage location. Light emitting diodes (LEDs) or other visual, audible or mechanical signaling devices are positioned in proximity to the stored products and are in electrical contact with the labels on the products, as well as with a central processing unit (CPU) or other equipment used to specify and select the product.
