Abstract:
A device such as an electric motor, an electric generator, and a regenerative electric motor includes a plurality of independent energizable electromagnetic assemblies. Each independent electromagnetic assembly has an associated one-piece magnetic core formed from thin film soft magnetic material. Each independent electromagnetic assembly defines two stator poles located at opposite ends of the one-piece magnetic core. Each one-piece magnetic core provides the entire magnetic return path for the two opposite magnetic stator poles associated with each independent electromagnetic assembly.
Abstract:
A fluid system has a fluid control device that can receive a gas hose and fluid hose. The fluid control device can also have a gas source and can be configured to receive the liquid hose. The fluid control device is provided to output a fluid flow into an output hose. The fluid control device can be positioned near a liquid source or a nozzle of the output hose. In another arrangement, the fluid control device can receive low pressure fluid and deliver high pressure fluid to a high pressure device. The fluid system can have a hose reel apparatus for spooling a hose connected to the fluid control device and the high pressure device.
Abstract:
A generator is provided along a conduit that carries a man-made fluid flow. The generator generates electrical power that can be, e.g., used to charge a battery, rotate a reel, or to directly control a fluid flow control valve associated with the fluid flow. In the garden hose context, neither AC power nor frequent battery replacement is required because power from the generator can recharge the battery powering the valve and the reel.
Abstract:
A hand crank assembly system for spooling linear material onto a reel includes a reel drum onto which the linear material can be spooled and a lever pivotable about an axis. A torque transfer mechanism of the system has an engagement clutch that engages and transfers a torque when it is operated in a first rotational direction, but that does not operate nor transfer a torque when it is operated in a second rotational direction opposite the first rotational direction. The torque transfer mechanism converts the pivoting of the lever into the rotation of the reel drum in the first rotational direction regardless of the direction in which the lever is pivoted.

Abstract:
A reel includes a reel drum enclosed within a housing comprising a first housing portion, a second housing portion, and a middle housing portion positioned therebetween. A spindle member has a first end connected to the first housing portion and a second end connected to the second housing portion. The spindle member extends through an opening in the drum so that the drum is rotatable about a spindle axis defined by the spindle member. The middle housing portion encircles the drum and has an aperture through which linear material can extend, the linear material of a type that may be spooled on the drum. The middle housing portion is rotatable about the spindle axis independently of the drum. In preferred embodiments, the reel is a cord reel and the linear material is electrical cord. In preferred embodiments, the middle housing portion is rotatable at least 360° about the spindle axis. In preferred embodiments, the drum is powered by an electric motor. In preferred embodiments, the housing is substantially spherical and the reel further comprises one or more support structures that include handles and are configured to prevent the housing from contacting a flat surface such as a floor or wall. In preferred embodiments, one or more temperature-sensitive switches are configured to shut off power to a spooled electrical cord in the event that a temperature of the reel exceeds a given threshold. In preferred embodiments, a solenoid is provided for locking the middle housing portion with respect to the first and second housing portions while the motor is rotating in a direction to spool the linear material onto the drum.

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.
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.
