Omni-directional wind turbine

An omni directional, vertical discharge wind turbine, consisting of a shroud that captures wind from any direction and directs it to flow vertically through a throat section where an aerofoil multi-bladed rotor is mounted. The rotor shaft is connected to an electrical power generator. The intake of the shroud incorporates multiple horizontally curved blades of toroidal form varying up to nearly twice the size of the rotor diameter, stacked, staggered and secured in place by multiple aerodynamic vertical walls in the radial direction, to form a central collection chamber for wind. The blade curving angles and the stacking arrangement are such that while accelerating and focusing the wind, across the full swept area of the rotor blades, the loss of air from the central collection chamber is significantly reduced by air flow forming a fluid dynamic gate across inactive faces. Utilizing a wedge and collar near the open top discharge the free wind stream flowing across the open top assists in increasing the flow of air through the rotor. With the increased extraction and wider operational envelop, the energy produced per annum of this omni-directional shrouded vertical wind turbine is anticipated to be much higher than that of a standard free wind turbine of same rotor diameter.

Shielding method of application push message and intelligent terminal

The invention provides a shielding method of an application push message, which comprises the steps that an intelligent terminal receives application information with a message push function by a network, and a list is built according to the received application information; the intelligent terminal detects a message shielding operation which is carried out on an application in the list by a terminal user, and a shielding list is built according to a detection result; when receiving a push message request which is sent by a certain application or message contents which are directly pushed by the certain application, if the intelligent terminal judges that the application belongs to the list and the shielding list at the same time, the intelligent terminal does not respond to the message push service of the application. According to the shielding method of the application push message and the intelligent terminal, the message push service of the applications is subjected to unified management, messages which are pushed by the applications are screened, the user is prevented from being disturbed by too many application notifications, or the user is prevented from being perplexed by the push messages of the applications, which are not needed by the user, and therefore, the information using efficiency is increased, and the communication efficiency is improved.
