Abstract: A toy vehicle with an adjustable chassis is disclosed. The toy vehicle comprises a chassis having a left frame rail and a right frame rail. Each of the left and right frame rails is moveable between a first position and a second position. One or more wheels are attached to each of the left and right frame rails and a vehicle body is mounted onto the chassis. Moving the left and right frame rails to their first positions results in the left and right frame rails moving toward each other and toward the vehicle body. Moving the left and right frame rails to their second positions results in the left and right frame rails moving away from each other and away from the vehicle body.

Abstract: A tamper-resistant or tamper-evident keypad device for use in secure transactions. The keypad comprises multiple security mechanisms to prevent tampering to the device, and thus access to users' private information. The keypad is made of resilient materials and contains a tamper-resistant collar for housing the keypad's connector interface. The keypad comprises a multi-layered printed circuit board with at least two internal security-shield layers comprising switch trace protection, as well as additional security layers for tamper protection. The keypad comprises a silicon-rubber keypad actuator that engages tamper switches on the flexible security circuit. The keypad comprises metal discs mounted on the front or rear face of the flexible circuit and an optional dome layer.

Abstract: A reaction container has contains an amount of a water reactive material and a volume of water within the confined space of its interior. The water reactive material, which contains aluminum, is formed as two separate and spaced apart portions. The water is located between the two portions of the water reactive material. A detonation mechanism, which is configured to mix the amount of water reactive material and the volume of water, is provided in communication with each portion of the water reactive material. The volume of water and the aluminum in the water reactive material are stoichiometrically balanced.

Abstract: A toy vehicle. The toy vehicle includes a body with at least one rollable wheel operatively connected to the body, and a pneumatic system operatively connected to the body and configured to store a pressurized gas and release stored gas upon a triggering event. A lifter is operatively connected to the at least one wheel and is configured to use energy from the pressurized gas to cause the toy to jump responsive to the triggering event, at least in part, by extending the at least one wheel.

Abstract: A toy vehicle. The toy vehicle includes a base, a plurality of wheels spinably connected to the base, and a pneumatic piston operatively connected to at least one of the wheels. The toy also includes a plurality of body pieces at least partially covering the base, and a pneumatic disassembly mechanism operatively connected to at least some of the plurality of body pieces. A pneumatic system is configured to deliver pressurized gas to the pneumatic piston to cause at least the base to jump by extending the at least one wheel away from the base. The pneumatic system is also configured to deliver pressurized gas to the pneumatic disassembly mechanism to separate at least some of the plurality of body pieces from the base.

Abstract: Toy raceways and finish line apparatuses for toy raceways are disclosed. Toy raceways may include a plurality of hingedly coupled multi-lane track segments, a starting apparatus, and a finish line apparatus. The plurality of hingedly coupled multi-lane track segments may be configured to foldably transition between a first configuration and a second configuration. In the first configuration, the plurality of hingedly coupled multi-lane track segments may be aligned to provide a multilane toy raceway, which may have a first end and a second end. In the second configuration, the plurality of hingedly coupled multi-lane track segments may produce a stack of folded track segments. The starting apparatus may be disposed proximate the first end of the toy raceway, and the finish line apparatus may be disposed proximate the second end of the toy raceway.

Abstract: A toy vehicle. The toy vehicle includes a core and a plurality of wheels rotatably coupled to the core. A jumping assembly operatively connected to at least one of the wheels is configured to cause the toy to jump at least in part by extending that wheel away from the core. A jump selector has at least a first state, and a second state, and the toy does a rotating jump when the jumping assembly causes the toy to jump and the jump selector is in the first state, and wherein the toy does a less-rotating jump when the jumping assembly causes the toy to jump and the jump selector is in the second state.
