Abstract: Control of an energy storage and provisioning system is disclosed, including a method in which electrical power is received from a power generator in an energy storage system having energy storage cells. Each of the energy storage cells has switching elements selectively operable to connect with terminals of other energy storage cells.

The method further includes storing the received electrical power into the subset of energy storage cells arranged into the topology configuration to optimize storage of the electrical power received from the power generator.

Abstract: The present invention provides an anti-entrapment device for an aerial lift having a basket or cage. The anti-entrapment device comprises an elongate housing; two or more sensors housed within said elongate housing and a switch activation device coupled to the elongate housing. At least one of said two or more sensors is positioned proximate an end of said elongate housing. Said switch activation device is arranged at an angle to the orientation of said sensor(s) positioned proximate the end of said elongate housing. The sensors are arranged to provide a detection zone and to detect obstacles within the detection zone. The sensors are configured to facilitate the alerting of an operator standing in a basket or cage to the presence of an obstacle that may potentially strike the operator before the strike occurs, and the switch activation device is configured to prevent further movement of the basket or cage once the switch activation device is activated.

Abstract: A reconfigurable rotating electric machine having a rotor to rotate in association with a stator. Coils are arranged to form the windings of one or more phases. Each coil or group of coils has a pair of terminals to receive an electrical input. Switches are arranged to connect each coil or group of coils in series or parallel with another coil or group of coils to form defined coil topology configurations. A processor has memory storing settings to determine a state of each of the switches for each of the defined coil topology configurations. The switches are controllable to connect the coils into a force expansion topology configuration to form an electrical machine having two, four, or more virtual poles.

Abstract: This application generally relates to electric machines with coils or windings (e.g., generators and motors), and more particularly to systems, apparatus, and methods that configure coils or windings of electric machines, for instance dynamically in response to operational condition and under load.

Abstract: A furniture clip to attach to the ends of a webbing strap in a system of webbing for an article of furniture. The clip is provided with prongs to be inserted into a groove provided on the framework of the article of furniture. The clip is further provided with teeth to retain the strap, wherein the strap is inserted into the clip and a user clamps the clip onto the strap using a pair of pliers or a vice. When clamped onto a strap, the prongs of the clip protrude at a 45-degree or 90-degree angle. The angle may be modified to accommodate furniture which requires the prongs to protrude at angles other than 45 or 90 degrees.

Abstract: Real-time topic analysis for social listening is performed to help users and organizations in discovering and understanding trending topics in varying degrees of granularity. A density-based sampling method is employed to reduce data input. A lightweight NLP method is utilized for topic extraction which provides an efficient mechanism for handling dynamically-changing content. In embodiments, the social analytics system further helps users understand the topics by ranking topics by relevance, labeling topic categories, and grouping semantically-similar topics.

Abstract: One or more variable configuration controller (VCC) systems may produce various combinations of series or parallel couplings of coils, winding or inductive elements of an electric machine such as a generator and/or electric motor. The VCC systems include a plurality of bridge rectifiers, and a first number of switches operated to selectively couple respective pairs of coils in series from parallel on an AC side of the bridge rectifiers. The bridge rectifiers provide for automatic electrical isolation of coils on occurrence of open circuit, low voltage or short circuit conditions. A second number of switches with different performance characteristics (e.g., speed, loss) than the first number of switches may be coupled in parallel with respective ones of the first number of switches. Power factor correction may be used.

Abstract: A polyphasic multi-coil generator includes a drive shaft, at least first and second rotors rigidly mounted on the drive shaft so as to simultaneously synchronously rotate with rotation of the drive shaft, and at least one stator sandwiched between the first and second rotors. A stator array on the stator has an array of electrically conductive coils mounted to the stator in a first angular orientation about the drive shaft. The rotors each have an array of magnets which are circumferentially equally spaced around the rotor and located at the same radially spacing with respect to the centre of the rotor and the drive shaft at a first angular orientation relative to the drive shaft. The arrays of magnets on adjacent rotors are off-set by an angular offset relative to one another.

Abstract: An electric machine may employ a distributed bearing, for example spaced radially outwardly of a longitudinal center of a rotor and stator assembly. The distributed bearing may take the form of a wire race bearing, which positions a rotor assembly relative to a stator assembly to maintain an air gap therebetween. The rotor assembly may be concentrically located within the stator assembly. Electrically insulative fasteners may couple a race assembly to the stator or rotor assembly. Compensation fastener assemblies may couple the wire race assembly to the rotor or stator assembly, to compensate for differential expansion for instance thermal differential expansion along a longitudinal axis of the electric machine. The electric machines may be arranged in series, for example with drive shafts arranged along a common axis, and may be coupled to the same source of motion (e.g., propeller of wind turbine, without or with a gear box).
