| 20120058675 | CONTROLLED DISCHARGE CONNECTOR LEAD - When a hobby enthusiast has recharged the battery for a remote controlled vehicle, such as a scale facsimile automobile, boat, helicopter or airplane, the battery must be connected again to the vehicle drive system, to provide power. This operation is typically performed by connecting each lead of an electronic speed controller to each corresponding lead of the battery, through a removable barrel receptacle lead and a mating barrel plug lead respectively, attached to each corresponding lead. An improved connector lead is described herein that protects components that may be attached to either lead in a connection. The charge dissipates in a resistive member that is physically coupled to a conductive member to form at least in part a first lead. When an improved lead is connected to a mating lead, the connection initially provides a charge dissipation path through the resistive member, but subsequently provides a bypass, current carrying conductive path around the resistive member from one component to another. By making use of an improved connector, electrical components are protected, not only from hot-swap current, but also from electrostatic discharge in general. | 03-08-2012 |
| 20080258658 | CONTROLLER FOR A MULTI-PHASE BRUSHLESS DC MOTOR - Control of rotational speed of a direct current multi-phase brushless motor is provided using an apparatus and method that works at low speed but does not depend upon Hall effect sensors. An apparatus for accelerating rotation of the motor shaft has a power stage circuit coupled to a back Electromotive Force (EMF) sensor circuit and a microprocessor. The power stage pulses at a duty cycle less than 100% under control of the microprocessor. The back EMF sensor circuit measures an order with respect to voltage of at least one phase relative to one or more other phases during off-time. The microprocessor determines one or more phases to be pulsed, and the polarity of the pulses based on the measured order. A method for sustaining rotation pulses the phases, measures order with respect to voltage of at least one phase relative to one or more other phases, and updates commutation state based on the measured order. A method of accelerating rotation generates one or more power pulses, determines an order with respect to voltage of one phase relative to one or more other phases, and generates subsequent pulses on phases and with polarity determined by the measured order. | 10-23-2008 |
