Abstract: In one aspect, there is provided a toy vehicle that includes a vehicle body, at least one motor and a plurality of wheels. The at least one motor is mounted to the vehicle body, and is sized to have a selected amount of torque. The plurality of wheels includes at least one driven wheel which includes at least one flip-over wheel which has an axis closer to one end of the vehicle than the other end. In an upright orientation the vehicle body extends above the plurality of wheels. The toy vehicle has a centre of gravity that is positioned, such that, application of torque from the at least one motor causes the vehicle body to drive rotation of the vehicle body about the axis of rotation from an inverted orientation over to the upright orientation.

Abstract: 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.

Abstract: In one embodiment, a data storage system includes a server system that includes a processor and a local buffer pool configured to store 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, where the at least one DASD includes an integrated catalog facility (ICF) configured to provide at least one catalog, and where the data storage system is configured to provide record level sharing (RLS) for the at least one catalog stored to the at least one DASD.

Abstract: Systems, methods, and computer program products are described for providing record-level sharing (RLS) for data sets to local users of a system. In one embodiment, a process includes requesting access to a data set from a record-oriented file system in which the file system manages records on behalf of one or more users, and the access is requested for a first local user. The process proceeds by locking the data set in the file system such that no direct access of the data set is allowed. Read and/or write requests for the data set are processed using the representation of the data set in the designated server address space. The data set in the file system is updated with any changes made to the representation of the data set in the designated server address space.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
