A system for providing a user interface includes a first element tag and a second element tag. The signal processing circuit makes signal processing on the camera data read from a camera data area of an SDRAM to produce YUV data for record. Some embodiments include simultaneous bidirectional communications between memory devices and a controller by assigning multiple frequency pass-bands to each memory device or bank of memory devices. The base flange is rigidly attachable to a concrete form. The viscosity is such that an amount of levelling will occur will be equal to the distance between any cells, but that cell to cell levelling will not, in general, occur.
