The systems and methods of the invention relate to providing a computer device, having a display unit, with an accelerometer (or other motion sensor) to detect movement of the computer device (and/or an associated display unit) and generate movement data. An accelerometer driver may receive the generated movement data. The generated movement data may be processed and/or interpreted in order to create one or more control signals. The control signals may be sent to a display driver to control movement of one or more selected display objects on one or more display units. The control signals may control movement of selected display objects on a screen display (or between multiple screen displays) associated with the computer device.

The invention discloses an inclined separated layer solid filling coal mining method for a super thick coal seam, which is suitable for the exploitation of an 'under three' super thick coal seam. The method comprises the following steps: determining the number of inclined separated layers according to the principle that thickness of each separated layer is 2.5-4.5 m; adopting a exploitation sequence that mining layer by layer, and filling at a next row; arranging tunnels and equipment according to the conventional solid filling coal mining method; carrying out a circulating sequence that coal mining firstly, metal nets and bamboo fences paving secondly, and filling finally to complete the filling exploitation of a first mining surface and a first separated layer; meanwhile, mining according to the same filling coal mining method under the shield of a manual false roof formed by the first separated layer at the corresponding position of a second separated layer 4 months after a working face of the first separated layer finishes mining; circulating in the way that the exploitation of one separated layer is performed under the shield of a manual false roof manufactured by an upper separated layer continuously until the whole super thick coal seam is mined out. Through the adoption of the method, resources of the 'under three' super thick coal seam can be utilized, the rock formation movement and earth surface sinking can be effectively controlled; and the recovery ratio is high, the production efficiency is high, the cost is low, and the method has wide practicability in the field of thick coal seam filling exploitation.

Devices and methods are provided for replacing a spinal disc, and in particular devices and methods are provided that rely on buckling to control movement of adjacent vertebrae. In one embodiment, an artificial disc replacement implant is provided and includes an implantable body having a superior surface adapted to be positioned adjacent to an endplate of a superior vertebra, and an opposite inferior surface adapted to be positioned adjacent to an endplate of an adjacent inferior vertebrae. The implantable body includes at least one wall formed therein and extending between the superior and inferior surfaces. The wall(s) can be adapted such that, when the implantable body is disposed between the endplates of adjacent superior and inferior vertebrae, the wall(s) will buckle by moving laterally and shorting in height under a load applied thereto by movement of the adjacent vertebrae. The implantable body can also include at least one opening formed adjacent to the wall(s) and extending between the superior and inferior surfaces of the implantable body.
