Abstract:
Methods are provided for treating a subject for a fertility condition. In accordance with the subject methods, at least a portion of a subject's autonomic nervous system is modulated to increase the sympathetic activity/parasympathetic activity ratio in a manner that is effective to treat the subject for the condition. Embodiments of the subject invention include modulating a subject's autonomic nervous system using electrical energy and/or one or more pharmacological agents. The subject methods find use in the treatment of a variety of different fertility conditions. Also provided are kits for use in practicing the subject methods.
Abstract:
A method for interfacing products with a web browser comprises retrieving a product profile, the product profile associated with one product. An agent type is determined based, at least in part, on the product profile. Data is retrieved from the product based on the agent type and processed such that the data is accessible by the web browser.
Abstract:
A watercraft incorporating electrical power generation from human kinetic power, and electrical energy storage to enable amplification of human-power to propulsion power to achieve increased watercraft speeds. Control electronics enable operator-adjustable variable electronic gearing, and an assortment of torque vs. speed loading characteristics of the generator, thereby providing optimal pedal cadences and enjoyment for a wide variety of operators. An optional photovoltaic solar panel augments the power generation to extend travel time with power amplification, and recharges the energy storage system. This invention provides a pleasure watercraft that is simultaneously lightweight, low cost, low maintenance, environmentally friendly with zero pollution, ultra-low noise, and thrilling to operate, while simultaneously providing a means of enjoyable exercise for operators of nearly all abilities.
Abstract:
A KVM extension configuration that includes a host connected to a transmitter for transmitting communication signals across a KVM extension to a receiver where user interface devices are located. The host has a motherboard that supports USB communications. The KVM extension configuration includes a USB host controller at the receiver that initiates data reads and writes to the host as delayed transactions and supports USB protocol communication with a plurality of the user interface devices. The configuration also includes a transmitter core in the transmitter having shadow registers that include content that is copied from the configuration registers of the USB host controller at the receiver. The host successfully carries out USB communications with the transmitter through the use of the content of the shadow registers. In addition, the receiver periodically synchronizes the content of the shadow registers with content from the configuration registers of the USB host controller.
Abstract:
Methods and systems consistent with the present invention perform enhanced services for wireline and wireless subscribers in an integrated wireline and wireless switching system. The enhanced services may include, for example, group dialing plans, message waiting indicator activation, call forwarding, simultaneous ringing, call conferencing, calling line identification, automatic call back, automatic recall, speed dialing services, and/or any other services that may be provided by a switching system to wireless and/or wireline subscribers. When a calling wireline and/or wireless subscriber requests one or more of the enhanced services, the integrated wireline and wireless switching system determines the line types associated with the wireline and/or wireless devices of a called subscriber, and identifies references to one or more shared procedures for performing the enhanced services according to the determined line types without creating direct dependencies between wireline and wireless modules in the integrated wireline and wireless switching system. Finally, the integrated wireline and wireless switching system executes the identified procedures to perform the shared services.
Abstract:
A method for fabricating an induction motor rotor lamination includes using an indexed notching die to punch a plurality of closed rotor slots at -different distances from a center point of rotation by punching a first rotor slot, changing the position of a center point of the rotor lamination with respect to the notching die, and punching a second rotor slot. In another embodiment, a plurality of rotor slit patterns are punched using a variable depth indexed notching die including at least two rotor slit punching portions, one being deeper than another, by punching a first rotor slit pattern, changing the depth of closure of the notching die, and punching a second rotor slit pattern with the second rotor slit pattern having a different number of rotor slits than the first. In another embodiment, each rotor slit is open to and off center with respect to its respective rotor slot, and rotor laminations are stacked by positioning some of the rotor laminations in an orientation with is turned over and rotated with respect to others of the rotor laminations; filling the rotor slots and the rotor slits with cage material; and machining outer surfaces of the rotor laminations. In another embodiment, uniformly spaced identical rotor slots are punched and modulation is created by punching a contoured outside diameter or by inserting slot wedges of molded magnetic material.
Abstract:
A drive system comprises a rotor position and velocity tracker adapted to decouple fundamental frequency effects of a zero sequence signal of an induction machine from the zero sequence signal and to use a resulting error signal to estimate a position and a velocity of a rotor of the induction machine.
Abstract:
A system for speed-sensorless control of an induction machine includes a flux regulator & torque current calculator for operating the machine in a heavily saturated state to produce a saturation induced saliency; a saliency tracker for tracking an angle of the saturation-induced saliency; a signal injector for injecting an AC signal aligned with a saliency axis; voltage and current determiners for determining stator voltages and currents; and a rotor flux calculator for using the saturation-induced saliency angle, the determined stator voltages, and the determined stator currents to determine a magnitude and a location of a rotor flux vector. The flux regulator & torque current calculator is adapted to use the rotor flux vector to control the induction machine.
