Abstract: A method of making a stator module for use in a stator assembly of an electric machine includes temporarily supporting a plurality of stator segments in a desired orientation using a temporary support. The desired orientation of the stator segments is a relative orientation of the stator segments within the stator module. A mold is placed around the plurality of stator segments and the mold is filled with a potting material to form a stator module such that the potting material supports the stator segments in their desired orientation. The temporary support is removed.

Abstract: An electrical energy storage system includes a plurality of electrical energy storage modules with each module having an associated operating voltage and each module being capable of outputting electrical power at a variable current at the associated operating voltage. The system further includes a plurality of electrical power modulation circuits electrically connected to an associated one of the modules thereby allowing the associated module to be electrically isolated from the other modules. Each power modulation circuit includes an arrangement for receiving the operating voltage and current of the associated module, transforming the operating voltage and current, and outputting electrical power at a voltage that is independent of the module operating voltage of the associated electrical energy storage module.

Abstract: Preferred embodiments of the invention comprise an automatic reel capable assisting a user when attempting to unspool a linear material, such as a water hose. The automatic reel includes a control system having a motor controller capable of sensing a pulling of, or increased tension of, the linear material and capable of causing a motor to rotate to unspool the linear material. In certain embodiments, the motor controller tracks the length of the unspooled portion of the linear material and/or reduces the spooling speed of the motor when retracting a terminal portion of the linear material.

Abstract: The present invention relates to a system and components thereof for intelligently watering an environment. The system comprises at least one sensor for monitoring particular environmental conditions, and at least one electrically powered valve that receives wireless information signals from the sensor and controls a watering device based on the signals. Power control units repeatedly toggle the sensor and valve between powered and unpowered states to conserve energy. The power control units are configured so that the powered states of the sensor and valve overlap in time to make it possible for the valve to receive the wireless information signals from the sensor.
