摘要:
A method and structure negating thermal inertia of a solid portion, such as shielding, which influences mechanical behavior of parts of an engine structure, by reducing forces transmitted to the engine structure during an event in which a turbine blade ruptures, while preserving mechanical strength and vibratory positioning. The structure includes a flexible fastener for a shield, enabling producing a fusible section. An assembly for mounting a shielding onto a casing of the engine structure of a turbine includes connection lugs and points for attachment to the casing and shielding. The attachment points are sufficiently spaced apart in accordance with curvature of the shielding and casing so connection between the lugs and the shielding or casing, and connection of the attachment points, are substantially tangential. The lugs are sized so the connection has sufficient flexibility to control vibratory positioning thereof and ensure sufficient mechanical strength under thermo-mechanical loads.

A mechanical protection device including: a transmission shaft having a main axis of rotation and an element that is frangible under a torsional overload; a movable member secured to the transmission shaft to rotate about the main axis and configured to move radially outwards relative to the main axis from a first position to a second position; a spring urging the movable member towards the first position; and a tangential abutment configured to stop rotation of the movable member about the main axis when the movable member is in the second position. The movable member and the spring are calibrated so that from a predetermined trigger angular speed the movable member moves from the first position to the second position under effect of centrifugal force greater than prestress of the spring.

Technologies are generally described for data filtering for communication devices. In one example, a method of receiving data from a data source on a communication device is disclosed. The method includes determining, at the communication device, a domain name of the data source. The method also includes determining, at the communication device, one or more communication networks the communication device is connected to. The method further includes processing, at the communication device, the domain name for acceptance based on the one or more connected communication networks. The method also includes receiving the data from the data source, at the communication device, if the domain name is accepted.
摘要:
A device for filtering intake air of an internal combustion engine, including at least one filtering element including an inlet for air being treated, a first clean air outlet toward the engine, and a second air outlet toward the outside, and a ventilation mechanism driving the air from the second air outlet. The ventilation mechanism includes a fan wheel driven by a turbine set into motion by a gas flow taken from the engine.
摘要:
An apparatus for interaction of a plurality of users with an application, comprising: a plurality of pointing devices (10) capable of emitting a signal (80; 110) (such as visible or infrared light, a laser or omnidirectional flashes), each pointing device comprising one or more triggers; a presentation device (20) (such as display, a wall, or any objects); and detection means (30) (camera, stereo camera, other) capable of detecting said signal (80; 110). The apparatus also comprises means (30, 40) for detecting trigger actions by said users, and recording the identity and time of said trigger actions (30, 40), means (40, 13) for enabling said pointing devices (10) to emit said signal (80; 110) and means (40) for enabling said detection means (30) to detect said signal (80, 110), and for linking said signal detection to a specific pointing device (10) trigger action.
摘要:
A fan unit (10) for purifying air comprises a fan housing (20), a rotatable fan body (30)disposed within the housing (20), the fan body having a flow inlet cavity (36) and an air purifying lamp (40) disposed at least partially within the flow inlet cavity (36), whereby, in use, air drawn into the housing (20) through the flow inlet cavity (36) is purified by radiation emitted from the lamp (40).
摘要:
In an airport baggage handling system bag information, flight information and airport topology information are provided to a central processor which determines a path for the bag through the handling system. The bag is scanned at various points along the path and the scan time is compared with a predetermined arrival time for the bag at the scan point. A bag is marked at risk if it arrives at a scan point after the predetermined time and the system may suggest an alternative handling path for the bag if it is determined that the risk of the bag not making an outbound flight is too high.

摘要:
A lubrication device including a bypass valve with an inlet connected to a feed circuit, a first outlet to be connected to elements to be lubricated, and a second outlet connected to a bypass circuit. The valve includes a valve member slidable between first and second positions, and separating a cavity into first and second chambers. The first chamber is connected to the inlet. In the first position, a fluid flow passage from the first chamber to the second chamber is open, and from the first chamber to the first outlet is closed. In the second position, a fluid flow passage from the first chamber to the first outlet is open, and from the first chamber to the second outlet is closed. At least in the second position, the valve member separates the chambers in substantially leaktight manner, while the second chamber remains in fluid flow communication with the second outlet.
