Methods and devices employing zero-bias display turn-off circuitry, including turn-off logic and switching devices, are provided. A bridge between the device controller and the mesh is described which buffers the data from the memory in cache lines from which the data is delivered finally to the IO device. Thus, the resulting image is re-oriented with respect to the first coordinate system. The first and second opposing part hemispherical socket portions are securable in a relationship which forms the part spherical cavity therebetween.
