Abstract: According to the present invention, an image coding apparatus provides a run-length encoding unit (RLE1) that subjects quantized coefficients which are obtained by quantizing frequency components of an image signal to a variable length coding process by using a run value (Run) that indicates the number of successive zero coefficients and a level value (Lev) that indicates a value of a non-zero coefficient following the zero coefficients. The run-length encoding unit (RLE1) includes a reordering unit (Lreodr) for reordering level values (Lev); a variable length coder (LVLC) for coding reordered level values (ROLev) by using a code table that is selected according to the value of a quantization parameter (QP); a reordering unit (Rreodr) for reordering run values (Run) from high frequency component of the quantized coefficients to low frequency component; and a variable length coder (RVLC) for coding reordered run values (RORun) by using a code table that is selected according to the number of already-processed run values. Accordingly, a variable length coding process for quantized coefficients is carried out at a higher coding efficiency, with redundant information included in the coefficients being effectively reduced.

Abstract: Floating electrically isolated active impedance modules are formed to attach to power transmission lines without breaking the lines such that the power line forms a secondary of the main transformer of the module. Each module includes an electrical energy storage device and a switching circuit, such as a single phase inverter, connected to the storage device and to the main transformer primary winding. The inverter can be controlled to couple a selected voltage to the transmission line through the main transformer primary winding which can provide effective positive impedance, negative impedance, or a voltage at or near phase quadrature with the line current. Many active impedance modules may be distributed over a power system grid to allow control of the impedance of the power lines in the grid and to steer power through the grid, with each module electrically isolated from ground and from other phase lines of the transmission system.
