摘要： A hand held steam vacuum is provided that is operated by way of a single switch device. The vacuum is generally comprised of a vacuum fan, a water pump, a heating element, and a fluid supply tank in fluid communication with a fluid discharge outlet. In operation, the vacuum fan is operable to suck debris into a collection bowl residing in the vacuum. In addition, the water pump is operable to drive fluid from the fluid supply tank via fluid transport tubes to the fluid discharge outlet, and the heating element is operable to heat the fluid prior to it being discharged from the fluid discharge outlet. A single switch device is configured to control operation of the vacuum fan, water pump and heating element.

摘要： A sense amplifier having three transistor stages. A balanced differential input stage with high noise immunity to capacitively coupled noise. A second threshold stage is provided with protection against an output being caused by a permanent potential on the input, false trigger protection circuitry, and protection against supply voltage and other minor variations. A differential output stage increases noise immunity of the amplifier output and protects against a short circuit in the output.

摘要： A battery boost apparatus is described. The battery boost apparatus monitors that amount of voltage in the vehicle battery and the current flowing to the vehicle battery to determine an existence of a fault condition. If a fault condition exists, a vehicle battery is cutoff from the boost battery and the charge of the boost battery is maintained until the fault condition is remedied.

摘要： A battery charging system enables rapid recharging of a working battery without immediate access to ac power and without the need for current limit and/or overvoltage protection. The battery charging system makes use of a charging battery having a number of cells that is greater than the number of cells in the working battery. The charging battery produces a charging current that is proportional to the difference in the number of cells in each battery. In this manner, the battery recharging system is capable of rapidly recharging the working battery. The number of cells in the charging battery is selected, however, such that the series voltage of the charging battery cells is less than or equal to the maximum rated voltage of the working battery. Thus, the voltage of the charging battery is greater than the operating voltage of the working battery but less than or equal to the maximum voltage rating of the working battery. As a result, the charging battery is generally incapable of overcharging the working battery, and therefore does not require current limit and/or overvoltage protection circuitry.

摘要翻译： 电池充电系统能够快速地对工作电池进行充电，而不需要立即访问交流电，并且不需要电流限制和/或过电压保护。 电池充电系统利用具有大于工作电池中的电池数量的多个电池的充电电池。 充电电池产生与每个电池中的电池数量差异成比例的充电电流。 以这种方式，电池充电系统能够对工作电池进行快速充电。 然而，选择充电电池中的电池数量，使得充电电池单元的串联电压小于或等于工作电池的最大额定电压。 因此，充电电池的电压大于工作电池的工作电压，但小于或等于工作电池的最大额定电压。 结果，充电电池通常不能对工作电池过度充电，因此不需要限流和/或过电压保护电路。

摘要： A battery-powered lawn mower includes a deck supported by wheels on a first side and a cutting mechanism having a first motor, including a first output member. A first cutting blade is driven by the first output member. A self-drive transmission has a second motor that selectively communicates an output to a drive axle. A force feedback controller measures a load on the first motor and changes an output voltage to the second motor based on the measured load.
