Abstract: A self-powered motor braking mechanism includes a dedicated power source sized for braking the respective motor and a dedicated braking circuitry configured to provide hybrid braking of the motor to a targeted stop. The motor braking circuitry is configured, in the event of a loss of primary power driving the motor, to provide a combination of two or more of dynamic braking, active braking and active position control to achieve zero speed of the motor by a target stopping time.

Abstract: The disclosed technology relates to a method and system for localizing and confining an autonomous mobile work system or systems for performing work in a user defined space. The system can include two or more variable reflective base stations at first and second locations that can modify their optical or electromagnetic reflectivity based upon either an external command via wired or wireless communications interface, or automatically on a regular or asynchronous time schedule under programmed or user settable control. The system also can include one or more autonomous mobile work systems capable of sensing the state of the variable reflectance base stations via sensors such as electromagnetic or optical sensors capable of measuring distance to the reflective base stations.

Abstract: Disclosed is an alternator overvoltage protection circuit having a TRIAC and a MOSFET. The TRIAC is electrically connected to the MOSFET and the TRIAC is electrically connected to a magneto. The TRIAC is configured to ground the magneto when triggered by the MOSFET. The MOSFET is electrically connected to an alternator and configured to conduct when the alternator operates in an overvoltage condition. Also disclosed is a method of alternator overvoltage protection for a piece of outdoor power equipment, the method including providing a TRIAC and an alternator rotated by an engine having a magneto, wherein the alternator outputs a voltage when rotated by the engine. The method further includes configuring the TRIAC to ground the magneto when the alternator operates in an overvoltage condition, thereby disabling the magneto, which stops the rotation of the engine and stops the alternator from outputting voltage.
