Abstract: A connector for use in a negative pressure coolant system is disclosed. The connector connects coolant system circulating to an electrical component thereby allowing the coolant to circulate through the electrical component. The connector is made up of two components, a component side connector and a pump side connector, and can be in three positions: disengaged, semi-engaged and fully-engaged. An electrical component can be drained of its coolant while the connector is shifted from the fully-engaged position, to the semi-engaged position and to the disengaged position. This can be accomplished without shutting down the negative pressure coolant system, thus allowing a particular electrical component to be disconnected without affecting the cooling efficiency of other electrical components connected to the system. Because the coolant is drained, it will not spill on the electrical component and cause damage.

Abstract: A system and method for controlling toy vehicles has a plurality of pads coupled to a central station. Switches in the pads may be closed to select toy vehicles and the operation of motors for moving the vehicles forwardly, rearwardly, to the left and to the right and moving upwardly and downwardly a receptacle or bin for holding transportable elements (e.g. marbles). The pads may be set in a mode to allow sharing of a vehicle by more than one pad. The pads are connected by wires to the central station, and may be interrogated selectively, sequentially or simultaneously by the central station. The central station forms packets of signals representative of the switch closures of the interrogated pads, and transmits the packets over a modulated carrier frequency to receivers in the vehicles. Each of the packets includes a binary signal addressing the vehicle selected by the pad whose switch closures are represented by the packet of data.

Abstract: Each of first vehicles has an individual address dependent upon an insertion of a selective one of different keys into a socket in the vehicle. Each of the first vehicles is movable in any desired direction on a first support structure formed by intercoupling male detents on first beams and female detents on other beams, all of them having the same construction, and by intercoupling the male detents on the beams to female detents on blocks, all having an identical construction. The first support structure may be, but does not have to be, intercoupled with a second support structure formed by intercoupling beams and blocks of the same type as the b3eams and blocks in the first structure. The second structure defines a track on which an additional vehicle (e.g., monorail) addressable in the same manner as the first vehicles is movable in first and second opposite directions.

Each of a plurality of manually operated pads generates signals for addressing any unaddressed vehicle and for providing movements of, and the performance of functions in, the vehicle when addressed. Each pad communicates the pad-generated signals to a connected central station. The central station communicates these signals by wireless to the vehicles.

Abstract: Switches in pads may be closed to select toy vehicles and operate motors in the vehicles for moving (a) the vehicles in any direction and (b) a bin holding transportable elements (e.g. marbles). A central station interrogates the pads, forms packets of signals representative of the switch closures in the interrogated pads and transmits the signal packets to the vehicles. Each packet includes binary signals for addressing the vehicle selected by the pad providing the packet. When the pads are interrogated by the central station, the signals from the pads are routed to an accessory coupled to a smart port in the central station. When the accessory is smart, the accessory recodes the signals and sends the recoded signals to the central station for transmission to the vehicles. When the accessory is dumb, it passes the signals from the central station to the vehicle without recoding the signals.

Abstract: Each of first vehicles has an individual address dependent upon an insertion of a selective one of different keys into a socket in the vehicle. Each of these vehicles is movable in any desired direction on a first structure formed by intercoupling beams of identical construction and blocks of identical construction. The first structure may be intercoupled with a second structure formed from the beams and the blocks. The second structure defines a track on which a monorail addressable in the same manner as the first vehicles is movable in first and second opposite directions. The monorail has rollers for driving it on the track and positioning rollers contiguous to the side surfaces of the track for retaining the monorail on the track during its movement. Each of a plurality of manually operated pads generates signals for addressing any unaddressed vehicle and for operating the vehicle.

Abstract: When manually closed, switches in pads select toy vehicles and the operation of motors for moving the vehicles forwardly, rearwardly, leftwardly and rightwardly and moving upwardly and downwardly (and rightwardly and leftwardly) a receptacle for holding transportable elements (e.g. marbles). When sequentially and cyclically interrogated by a central station, each pad sends through wires to the station signals indicating the switch closures in such pad. Such station produces first binary signals addressing the vehicle selected by such pad and second binary signals identifying the motor control operations in such vehicle. Thereafter the switches identifying in such pad the motor control operations in such selected vehicle can be closed without closing the switches addressing such vehicle. The signals for each vehicle are transmitted by wireless to all of the vehicles at a common carrier frequency modulated by the binary signals.

Abstract: A vehicle may have a chassis, wheels rotatably mounted on the chassis and motors disposed on the vehicle for selectively rotating the wheels to (a) accelerate the vehicle forwardly and rearwardly, (b) spin-turn the vehicle (turn the vehicle on a substantially stationary position), (c) turn the vehicle to the right or left during the vehicle movement forwardly or rearwardly, and (d) move the vehicle forwardly or rearwardly at a substantially constant speed. Energy is introduced from a battery in the vehicle to an energy storage member (e.g. capacitor) in the vehicle and from the capacitor to a microprocessor in the vehicle. The microprocessor controls the operation of the vehicle motor(s) in performing individual ones of the movements specified in (a) to (d) above.

Abstract: A member (e.g. toy vehicle) is powered at first times and depowered at second times. The member includes a plurality of switches having first and second terminals defining open and closed states, the switches being normally open and actuatable to the closed state in a pattern defining the member's address. A vehicle battery provides an energizing voltage to the first terminals of the address switches. A vehicle microprocessor is operative in the vehicle depowered state with at least one of the address switches closed to open an additional switch, thereby preventing the battery voltage from being applied to the address switches in the vehicle. The microprocessor is operative, with the vehicle powered and with at least one of the address switches closed, to close the additional switch thereby providing for the introduction of the battery voltage to the addressing circuit for the vehicle and for the vehicle operation. Each address switch may form a circuit branch with an impedance (e.g.

Abstract: When manually closed, switches in pads select toy vehicles and the operation of motors for moving the vehicles in different directions and moving upwardly and downwardly (and rightwardly and leftwardly) a receptacle for holding transportable elements (e.g. marbles). When interrogated by a central station, each pad sends through wires to the station signals indicating the switch closures in such pad. Such station produces first binary signals addressing the vehicle selected by such pad and second binary signals identifying the motor control operations in such vehicle. Thereafter the switches identifying in such pad the motor control operations in such selected vehicle can be closed without closing the switches identifying such vehicle. The first and second signals for each vehicle are transmitted by wireless to all of the vehicles at a common carrier frequency modulated by the first and second binary signals.

Abstract: A key in a vehicle socket closes contacts to reset a vehicle microcontroller to a neutral state. Ribs disposed in a particular pattern in the key operate switches in a particular pattern in the vehicle to provide an address for the vehicle with the vehicle inactive but powered. When the vehicle receives such individual address from a pad within a first particular time period thereafter, the vehicle is operated by commands from the pad. The pad operates the vehicle as long as the vehicle receives commands from the pad within the first particular period after the previous command from the pad. During this period, the vehicle has a first illumination to indicate that it is being operated. When the pad fails to provide commands to the vehicle within such first particular time period, the vehicle becomes inactive but powered and provides a second illumination. While inactive but powered, the vehicle can be addressed and subsequently commanded by any of the pads including the pad previously addressing the vehicle.

Abstract: Pads remotely control the operation of vehicles. In each pad, (a) at least a first control provides for the addressing of one of the vehicles, (b) second controls provide for the movement of the addressed vehicle and (c) third controls provide for the operation of members (e.g. pivotable bins) in the selected vehicle. Each pad provides a carrier signal, preferably common with the carrier signals from the other pads. Each pad modulates the carrier signal in accordance with the operation of the pad controls. The first control in each pad provides an address distinctive to the addressed vehicle and modulates the carrier signal in accordance with such address. Each pad sends the modulated carrier signals to the vehicles in a pseudo random pattern, different for each pad, with respect to time. Each vehicle demodulates the carrier signals to recover the address such vehicle.
