    摘要: The present invention provides an improved device for minimizing the time delays associated with turning on and off the power switches or power transistors in a standard totem pole configuration. An improved saturation detector monitors each transistor to determine when it is in saturation and generates a feedback signal which is combined with the input signal to generate the appropriate time delay needed to improve the switching time of the transistor.

    摘要: This invention relates to a bi-polar power supply regulator. A regulator is shown and described which prevents undesirable and potentially dangerous power supply build-up in a power amplifier of the standard totem pole configuration. The regulator also enables one to construct a multi-amplifier system in a cost effective manner since the regulator controls the build-up in the bi-polar power supply which is used to drive several power amplifiers in the totem pole configuration.

    摘要: A vapor mitigation system includes at least one vacuum pipe constructed and arranged to collect vapors beneath the floor of a building and to vent the vapors and a blower coupled to the at least one vacuum pipe. The blower is constructed and arranged to create a vacuum under the floor of the building. The vapor mitigation system further includes a controller configured to dynamically control a level of power supplied to the blower. The controller adjusts the level of power supplied to the blower in response to one or more environmental measurements.

    摘要: A portable power supplying system includes an enclosure including at least one wheel mounted to a bottom portion of the enclosure, a battery secured within the enclosure, and a battery charger secured within the enclosure. The battery charger is electrically connected to the battery for charging the battery. The system further includes a DC/AC inverter secured within the enclosure. The DC/AC inverter is electrically connected to the battery, and is configured to convert a direct current supplied by the battery to an alternating current. The system further includes a power outlet including at least one female household electrical connection, and a transfer switch secured within the enclosure. The transfer switch is electrically connected to the DC/AC inverter, the battery charger, the power outlet and a power source input.
