摘要： An engine-sound accessory for an electric toy vehicle produces a sound output which varies its characteristics in proportion to an electric input to the toy vehicle. The apparatus measures the total electric current fed to the toy vehicle to produce a sound control signal proportional thereto. When two or more vehicles are fed from a common power source, the apparatus is responsive to the sum of the electric current fed to the two or more vehicles whereby variation in the electric current fed to one or both of the vehicles produces a corresponding variation in the sound characteristic.

摘要： A decorative light flashing apparatus employs a mass-damped dynamic microphone which preferentially responds to impulse-type sounds to trigger a timing circuit. The timing circuit produces pulses in response to the impulse-type sounds which drive a commutating circuit for sequentially illuminating a plurality of light sources in time to the impulse-type sounds.

摘要： A radio control system for a multi-controller, multi-vehicle, independently controlled toy vehicle system provides proportional steering and speed control without mutual interference. Each of a plurality of control sets repetitively transmits low-duty-cycle command bursts containing an identity code and steering and speed commands. The control sets transmit their command bursts asynchronously and, due to the low duty cycle of all transmissions, a high probability exists for non-inteference even when four or more control sets are simultaneously operated to control four or more toy vehicles. Each toy vehicle attempts to match any incoming command burst with a standard including an identity code unique to that vehicle. When a command burst is received which is correct in every respect, including the identity code, the steering and speed commands contained therein are stored and are executed until a new decodeable command burst is received. Command bursts which are not correct in every respect, due to noise or interference between control sets, are ignored and the previously stored commands continue to be executed.
摘要翻译：用于多控制器，多车辆，独立控制的玩具车系统的无线电控制系统提供比例转向和速度控制，而不会相互干扰。多个控制集合中的每一个重复地发送包含身份码和转向和速度命令的低占空比命令脉冲串。控制组异步发送其命令脉冲串，并且由于所有传输的低占空比，即使当四个或更多个控制组同时操作以控制四个或更多个玩具车辆时，也存在用于非干扰的高概率。每个玩具车试图将任何进入的命令突发与包括该车辆唯一的身份码的标准相匹配。当接收到包括身份码在内的各方面正确的命令脉冲串时，其中包含的转向和速度命令被存储并被执行，直到接收到新的可解码命令脉冲串。由于控制组之间的噪声或干扰，每个方面都不正确的命令脉冲串被忽略，并且继续执行先前存储的命令。

摘要： A toy vehicle game includes an endless track defining two generally parallel lanes along which toy vehicles including reversible rotary drive motors responsive to current polarity reversal are driven while being biased against one or the other of the side walls of the track depending upon the polarity of current supplied to the vehicle motor. Current is supplied to the track through contact strips and a control system which permits the operators to separately and independently control current to the contact strips. When the polarity of the current to one of the toy vehicles is reversed a boost in available average electrical power is made available to that toy vehicle for a first limited duration maximum period. After using the boosted average power the selected toy vehicle must return to its original lane to be operated there at a normal power level for a mimimum of a second limited fixed duration period before power boost is again available. A balancing control equalizes the maximum performance of the two vehicles.
摘要翻译：玩具车游戏包括限定两个大致平行车道的环形履带，沿着该循环履带，包括响应于当前极性反转的可逆旋转驱动马达的玩具车辆被驱动，同时根据电流的极性被偏压到轨道中的一个或另一个侧壁提供给车辆电动机。电流通过接触片和控制系统提供给轨道，该控制系统允许操作者分别地并独立地控制到接触片的电流。当向其中一个玩具车辆的电流的极性反转时，在第一有限持续时间最大周期内，该玩具车辆的可用平均电功率的提升是可用的。在使用升压的平均功率之后，所选择的玩具车辆必须返回到其原始车道，以在正常功率水平下操作在第二有限固定持续时间段的最小值，然后再次可用功率提升。平衡控制可以平衡两辆车的最大性能。
