Abstract:
A toy vehicle comprises a chassis having a front end, a rear end and first and second lateral sides extending between the ends. Two wheel trains are disposed on separate lateral sides of the chassis. Each train includes first, second, third and fourth wheels, a first pair of the wheels being mounted on separate axles fixed with respect to the chassis and a second pair of the wheels being mounted on separate axles movable along the first lateral side of the chassis. A separate continuous track extends about each wheel train so that the track engages over at least the first wheel and another other wheel. A separate linkage connects each second pair of wheels with the chassis and is configured to displace the second pair of wheels between a first wheel arrangement in which the wheels of the train are generally disposed in a single row, and a second wheel arrangement in which the wheels of the train are generally disposed in two rows and all the wheels engage the track. A separate ratchet and pawl mechanism connects each linkage to each first wheel so that the wheels drive the linkages. Two motors are mounted to the chassis and engaged with separate first wheels, the motors driving the wheel trains independently of each other to move the vehicle. A simulated blade and two body panels are rotatably attached to the chassis and connected with the linkages and are moveable between first and second positions.
Abstract:
A system and method for deterring catalytic converter theft are described. A variety of devices are described which can be installed as needed on the underside of a vehicle as part of a system to prevent easy access to the points where a catalytic converter is connected to the vehicle, thus deterring theft, or to prevent a catalytic converter from being removed from the vehicle after being disconnected from the exhaust system. The method comprises installing said devices to prevent this access. The devices may be installed separately or combined to protect multiple catalytic converters as needed and as dictated by the particular design of the exhaust system of a particular vehicle.
Abstract:
Multicast call blocking is reduced in TST switch fabrics with the aid of an m-entry data structure. Each entry corresponds to one of m timeslots, and has 2n sub-entries corresponding to n input ports and n output ports. An N-cast call X:(y→z1, z2 . . . zN) is representable by associating a selected entry's yth input sub-entry with z1, z2, . . . zN of the selected entry's output sub-entries. Upon receipt of a call, the data structure entries are sequentially examined to detect the first entry for which a yth input sub-entry is unused and z1, z2, . . . zN output sub-entries are unused. If such an entry is detected, the call is scheduled for transmission in the corresponding timeslot. If there is no such entry and if N=1 the call cannot be scheduled; but, if N>1 the call is divided into two or more calls and an attempt is made to schedule them as above.

Abstract:
This lighting fixture enclosure comprises a back housing and an adjacent front housing separable from the back housing. The back housing includes a base; and the front housing includes a cavity in front of the base and a wall partially surrounding the cavity and terminating in a free end adjacent the base. The back housing includes a cradle on said base for receiving a peripheral portion of one end of a wire feed-through conduit. The front housing includes a notch in the free end of said wall for receiving another peripheral portion of the conduit. A projecting leg on said front-housing wall receives clamping means which, upon operation, forces the front housing toward the back-housing base, loading the leg in a bending mode, and also clamping the conduit end between said cradle and the wall portion bordering the notch.
