The present invention discloses a take-off and landing system for carrier aircraft, which comprises a takeoff device and a landing device; said takeoff device is a bow side launch deck which is located at the front part of the aircraft carrier and extends from a track groove provided with a track guider; said landing device is a stern side rear bridge which is located at the rear part of the aircraft carrier and extends from a treadmill belt-type runway. The invention also discloses a take-off and landing method corresponding to the take-off and landing system. The take-off and landing system and the method thereof enhances advantages and avoids weaknesses with regard to the existing take-off technologies, reduces the difficulty and risk in the existing landing technology. The present invention is suitable for the take-off and landing of all kinds of carrier aircrafts and also makes a design to build a “pocket-sized aircraft carrier” become possible.

Various fuel injection systems and fuel injectors are disclosed that provide varying cooling rates for fuel injectors connected in series to fuel supply and drain rail. The local cooling rate for each injector is manipulated to balance the heat flux or heat transfer across the injectors disposed along the rail. The cooling rates may be manipulated by varying sizes of openings or slots in the nozzle case, by varying annular spaces disposed between the nozzle case and the portion of the injector body that houses the actuator and solenoid assembly, and by varying the size of annular spaces disposed between the nozzle case and the cylinder head. Strategic placement of slots in the nozzle case that direct more flow at the portion of the injector body that houses the actuator and solenoid assembly may also be employed. As a result, the operating temperatures of fuel injectors connected in series to a fuel rail can be manipulated and moderated so the downstream injectors are not prone to overheating.

The utility model discloses a backlight module and a liquid crystal display (LCD) using the backlight module. The backlight module comprises a light guide plate and a clamp for fixing the light guide plate. The light guide plate is formed by splicing of more than two sub-light guide plates. The backlight module used for the LCD of the utility model is characterized in that sub-light guide plates of modular design are used, and the light guide plate applicable to any sizes of the LCD can be formed by splicing of the sub-light guide plates. The backlight module has advantages of convenient processing and assembly, productivity improvement, material waste reduction and backlight module cost decrease.

A mechanically actuated electronically controlled fuel injector (MEUI) includes a first electrical actuator that controls the position of a spill valve, and a second electrical actuator to control pressure on a closing hydraulic surface associated with a directly operated nozzle check valve. The fuel injector is actuated via rotation of a cam to move a plunger to displace fuel from a fuel pumping chamber either to a spill passage, or at high pressure out of a nozzle outlet of the fuel injector for an injection event. The minimum controllable fuel injection quantity, especially as it relates to small closely coupled post injections following a large main injection, is accomplished by the inclusion of a Z orifice passage that maintains a fluid connection between a needle control chamber and the nozzle supply passage. The inclusion of the Z orifice passage slows the rate at which pressure drops in the needle control chamber to commence an injection event, but also hastens the rate at which pressure builds in the needle control chamber to end an injection event. The result is a smaller post injection quantity and, if desired, a longer, shorter or same dwell time between injection events.

Surfaces can be decorated with texture tiling and/or texture painting using one or more sample textures, such as BTFs. In a described implementation of texture tiling, a patch-based BTF synthesis algorithm is utilized. In an example embodiment, a mesh of a target surface is re-sampled to produce a dense mesh such that there is a one-to-one correspondence between vertices of the dense mesh and pixels of an image. Patch matching is then employed with a working image that corresponds to a working patch. In an example embodiment, the patch matching is effectuated using translations and rotations of the sample texture. In a described implementation of texture painting, irregular feature(s) of a sample texture are synthesized onto a target surface. In an example embodiment, user-specified constraints as to a desired foreground feature of a sample texture and an intended foreground region of a targeted surface are factored into a graphcut operation.

Rendering of a partially translucent object is performed using a set of parameter maps derived from data measuring reflectance and transmittance of light received at the surface of the partially translucent object. Data is captured from an actual object being modeled, rather than estimated based on internal structure and composition. Parameter maps relating albedo, thickness variation, and specular intensity and roughness are stored as textures to facilitate rendering. In addition, realistic illumination from high energy sources such as sunlight is effected by separating light into low frequency and high frequency components. Low frequency components are rendered by precomputed radiance transfer. High frequency components, which are not modeled well by precomputed radiance transfer, are modeled using a light visibility convolution integral to generate light visibility maps for positions of the high frequency light source. Contributions from the different frequency components are combined to yield a realistic appearance.
摘要:
A computer implemented method for generating a representation of structure for use in rendering a synthesized image is provided. The representation is a view-dependent displacement mapping that represents displacements along a viewing direction. This view dependency allows the representation to be used to determine self shadows as well as shading, occlusion and silhouettes when used during rendering for synthesis.
