摘要:
A toy vehicle has a chassis, at least a first drive wheel rotatably attached to the chassis and at least a first link having a first end pivotally coupled with the chassis. At least a first non-powered wheel is operably coupled with the second opposing end of the first link. The first link has two operative positions: a first, fully-retracted operating configuration in which the first link is wrapped at least partially around the chassis crossing the drive wheel axis of rotation and a second, extended operating configuration in which the first link is pivoted away and extended from the chassis. A second link can be pivotally coupled between and with the chassis and first link. Forces acting on the toy vehicle resulting from driving the first drive wheel can cause each link to pivot with respect to the chassis.

In one embodiment, a system includes logic adapted for receiving a first request to change a state of a first group of catalogs, determining which of a plurality of catalogs belong in the first group, adding a change request for each of the first group of catalogs to a queue for processing, causing processing of each change request in the queue to change the state of each of the first group of catalogs according to the first request, creating a first group result indicating successful or failed state change upon a catalog in the first group of catalogs finishing processing, passing the first group result to an adjacent catalog in the first group of catalogs, removing each catalog that has finished processing from the first group of catalogs, and outputting the group result when there are no adjacent catalogs available to pass the group result.

A radio controlled toy vehicle that has the ability to transform from a compact (narrow wheel track) configuration to an expanded (wide wheel track) configuration. The toy vehicle includes at least one driving wheel. Left and right main transformation arms are attached to left and right chassis bodies. A transformation drive is adapted to cause the main transformation arms to move towards or away from each other when the transformation drive is actuated, thereby causing the left and right chassis bodies to move towards or away from each other.

A radio controlled toy vehicle having a single driving wheel. First and second chassis bodies are located on opposite sides of the driving wheel, and the driving wheel and chassis bodies rotatably attached to a primary axle. Support wheels are rotatably attached to the chassis bodies at a location distal to the point of attachment of the chassis bodies to the primary axle. First and second reversible electric motors are drivingly connected to the driving wheel by drive train means. A radio control receiver is attached to one of the chassis bodies, and is adapted to independently actuate the electric motors in a forward or reverse direction in response to control signals sent by a radio control transmitter. When both of the electric motors are operating in the forward or reverse direction, the driving wheel propels the vehicle in that direction. When one electric motor is operating in the forward direction and the other electric motor is operating in the reverse direction, the vehicle will cease being propelled by the driving wheel, and the first and second chassis bodies are forced to rotate in opposite directions about the primary axle, causing the vehicle to be lifted and turned.

In one embodiment, a storage system includes a server system having a processor and a local buffer pool for storing instances for use in catalog requests, and a Direct Access Storage Device (DASD) subsystem electrically coupled to the server system and to at least one DASD, wherein the at least one DASD is adapted for providing at least one catalog configured according to a Basic Catalog Structure (BCS), wherein the at least one catalog includes at least one of: a user catalog including information related to locations of user data sets and system data sets stored to the at least one DASD, and a tape volume catalog including information related to locations of user data sets and system data sets stored to at least one tape medium, and wherein the data storage system is adapted for providing Record Level Sharing (RLS) for the at least one catalog stored to the at least one DASD.

A toy helicopter assembly having a guard that prevents the vertical lift rotors of the toy helicopter from inadvertently contacting any object while spinning. The toy helicopter has a body that includes a fuselage and landing gear. A drive shaft extends upwardly from the fuselage. A least one rotor is connected to the driveshaft. Each rotor is rotated by the driveshaft in a circular path through a predetermined plane of rotation. A plurality of loop structures are attached to the toy helicopter. The loop structures extend along curved paths, therein creating a guarded area within the curved paths. The loop structures are oriented so that at least part of the circular path that is traversed by the rotors extends through the guarded area.
