Abstract: A helical auger turbine and hydrokinetic device for use with electrical generators for producing electricity. A helical turbine blade may be mounted on a central shaft, and a flange extending perpendicularly to an edge of the turbine blade. The helical auger may be a multi-section auger having radial sections covering a radial arc of between 45 degrees and 180 degrees, and that are rotational molded with identical center sections. The auger may have tapered end sections. The radial and end sections may be interlockingly mounted onto the central shaft to enable the complete transfer of torque captured by the helical auger by a moving fluid media, such as a tidal water flow, to the central shaft. The adjacent surfaces of the radial and end sections may be flush with one another to reduce disruptions of the moving fluid flowing over the completed helical auger and rotating the assembled helical auger.
Abstract: Methods and systems for providing rapid call-forwarding are described.

The method further comprises receiving call-forwarding logistics and generating a call-forwarding record. The system for providing rapid call-forwarding includes a switch operable for receiving a selection by a subscriber of a feature code and a forward code, wherein the feature code is used to activate a call-forwarding service and the forward code is used in the place of a target address, a call-forward control computer operable for storing and recognizing the feature code and the forward code, and a call connector operable for executing the rapid call-forward service.
Abstract: A method for obtaining, in a quick way, a strong, compact and waterproof permanent-magnet rotor (3), intended for a synchronous motor (1), particularly for pumps of washing machines for industrial and domestic use and the like, of the external stator (2) type, comprising a cylindrical hollow core (6) surrounded by a plurality of permanent magnets (10) comprising the steps of arranging a cup-like body (7) with a base end (8a), a free end (8b) and a side wall (9) exhibiting a plurality of passing longitudinal recesses (12) which define, between the same, a plurality of positioning seats (13) for the magnets (10), providing to insert the core (6) into the cup-like body (7) and arrange the magnets (10) in said seats (13) and injecting a plastic material with obtainment of a cage-like structure (50) having opposite bottoms (27, 28) abutting at the ends (8a, 8b) of the cup-like body (7) as well as columns (29) extended between the opposite bottoms (27, 28) housed in the recesses (12).
Abstract: The present invention is a method and system for transferring calls among communicating devices connected through a public network. The service is offered by a public network to permit a party in a ongoing conversation to transfer a call to another communicating device that may be more convenient to use, such as from a mobile telephone experiencing static to a land-based telephone, or from a home telephone to a mobile phone as a party leaves the home. In a method according to the invention, the network first establishes a connection between two communicating parties. The network then receives from one of the parties a request to transfer the call to another communications device. The network then transfers the call. The invention may be entirely network-based, in which case there may be a database of transferee devices stored on the network.
Abstract: A clamp adapter for a catheter that has a clamp body that receives an elastomeric clamp bushing. In order to fix a catheter inserted into the clamp bushing, the clamp bushing is axially compressed by a clamp lid. For this purpose, the clamp lid is moved axially on the clamp body with a clamp lever by means of a slotted guide.
Abstract: Certain exemplary embodiments comprise a method, comprising storing, within a telecommunications network, contact information for each of a plurality of contacts, the contact information for at least one of the plurality of contacts comprising a telephone availability status; and updating the telephone availability status for said at least one of the plurality of contacts.

Abstract: Certain exemplary embodiments can provide a method, which can comprise automatically storing a sketch of a dataset that supports automatic determination of an estimator of properties of a dataset. The automatic determination can be based upon computed adjusted weights to the items included in a sketch of the dataset. The adjusted weights can be used to compute estimates on the weight of any subpopulation of the items in the dataset that is specified using a selection predicate. We propose the rank conditioning, the subset conditioning, and/or a Markov-chain based method to compute these adjusted weights. We also provide a method that provides upper and lower confidence bounds on the size of a subpopulation.
Abstract: Methods, systems, and computer-readable media are provided for dynamically recognizing and processing service order types in a network management system. Service type data for a new service order type is registered in a database table while the network management system is operating. Then, a service order is received in the network management system and the service order is parsed to determine if the received service order corresponds with the new service order type based on the service type data registered in the database table. If the service order corresponds with the new service order type, then the service order is processed by the network management system. If the service order does not correspond with the new service order type, then updated service type data may be registered in the database table.

Abstract: A process for manufacturing an outer stator for an electric motor whereby the stator comprises stator poles surrounded by coils. A laminar body of ferromagnetic material is prepared, with elongated form and provided with laminar protrusions. A coil of conductive material is then inserted around each of the laminar protrusions. The terminal zones of the laminar protrusions are then cut or separated and deformed in order to assume an outwardly curved form. Then, the laminar body is closed such that the laminar protrusions are in an internal position and adapted to serve as stator poles.
