A method for optimizing track performance comprising: is provided. The method involves measuring one or more track status data at one or more measurement sites of the track during a train pass though the one or more measurement sites. Followed by analyzing the one or more track status data against one or more baseline reference values to obtain a track status profile, and adjusting an operating parameter, a track parameter, or both the operating and track parameters, based on the track status profile, to optimize the track's performance.

A driven accessory comprising a first rotary clutch portion, a second rotary clutch portion, a wrap spring and an actuator. The actuator is selectively operable for generating a force that is applied to a second end of the wrap spring. The actuator includes an actuator input member that is rotatable about a rotary axis relative to the first rotary clutch portion. The actuator input member is axially movable along the rotary axis between a first position, in which the actuator input member is drivingly engaged to the first rotary clutch portion to cause the wrap spring to uncoil against a clutch surface on the first rotary clutch portion such that rotary power is transmitted between the first rotary clutch portion and the second rotary clutch portion, and a second position in which the actuator input member is disengaged from first rotary clutch portion.

A method and system for manufacturing complex, three-dimensional textile structures is disclosed. These textile structures may be large and heavy and difficult to maneuver without damaging them. The method enables various types of joints to be constructed between textile panels plus the application of patches and details onto the surface of these panels. The method minimizes handling and damage to the textile material. The method also reduces the manpower required during the manufacturing process, thus minimizing manufacturing time and cost.

The present invention provides a light weight, modular and rigid structure for supporting the transmitter loop of an airborne electromagnetic system. The airborne electromagnetic surveying system comprises a tow assembly connected to an aircraft, the tow assembly including a transmitter section comprising a transmitter coil for generating a primary electromagnetic field that induces a secondary electromagnetic field. The transmitter coil is supported by a generally rigid transmitter frame. The transmitter frame comprises a plurality of frame sections assembled in a way such that the generally rigid transmitter frame substantially retains a rigid shape during operation. The system may also include a receiver section located above the generally rigid transmitter frame in between the aircraft and the generally rigid transmitter frame for detecting the secondary electromagnetic field.

A cooling assembly for the stator of an electric machine provided with coils including heads is described herein. The cooling assembly includes a generally cylindrical cooling body provided with opposite longitudinal ends and at least one head-cooling element mounted to one of the longitudinal end of the body; the head-cooling element being so configured as to enclose heads of the coils and to receive heat conducting material therein.

A cooling arrangement for the stator of an electric machine provided with coils including heads is described herein. The cooling arrangement includes a generally cylindrical cooling body provided with opposite longitudinal ends. Heat transfer material embeds the heads of the coils and contact the cooling body. A coil head embedding assembly and method are also described herein.

The present invention relates to a novel building system, which provides structural building panels, headers, connectors, insulating foam, sealants and membranes, which collectively are used to erect a building structure for cost-effective, energy efficient, low carbon footprint, weatherproof and easy-to-assemble structures for use in warm or cold climates even in locations of the world where specialized labor is scant. The walls, floors, ceilings and roofs have both vertical compression-resistance strength and horizontal bending-resistance strength sufficient that the structural building panels can be used in both above-ground and below- ground building wall structural applications, including applications where buildings are exposed to severe wind and other weather, such as hurricanes, tornadoes and the like. Said panels can replace concrete, wood or steel and can be adequate to meet corresponding required strength specifications for typical residential, commercial, agricultural and manufacturing buildings. The invention further permits to clad the inside and outside of the resulting building with such materials which permit to create an aesthetically pleasing structure if desirable to the end user.

The present invention seeks to provide methods and systems for the online exchange of business services between merchants, wherein credit is approved and used to establish virtual value recognition documents such as gift cards or coupons and acquire gift cards or coupons of other merchants. The website owner can generate revenue by retaining a percentage of the gift cards or coupons and reselling them to non-merchant users at a discount to the gift card face value.

Systems and methods are provided for forming an optical element within a transparent material using an irradiating optical beam, where the irradiating optical beam is employed to induce internal refractive index changes in the transparent substrate. Optical elements such as bulk and gradient index lenses may be formed in the transparent structure according various embodiments of the disclosure. An optical element may be formed by selecting a refractive index profile for the optical element, determining a corresponding suitable spatially dependent irradiation intensity profile for producing the selected refractive index profile, focusing an irradiating optical beam within the transparent structure, and controlling an intensity and position of the focused irradiating optical beam within the transparent structure according to the spatially dependent irradiation intensity profile.

The method for CO2 capture includes operating a CO2 capture system with a large temperature swing in between the absorption stage and the desorption stage; utilizing a hybrid solvent comprising water, carbonic anhydrase and an absorption compound in the absorption stage; membrane filtering the carbonic anhydrase out of the hybrid solvent in between the absorption stage and the desorption stage and prior to the large temperature swing; and recycling the filtered carbonic anhydrase back into the absorption stage to maintain high enzyme concentration in the absorption stage.
