A circuit for correction of errors in a memory device comprises a data word byte counter 16, data encoders 18 and 20, a syndrome accumulator 22, a data word byte address generator 24, a comparator 26, a decoder 28 and an error correction enable buffer 30. The apparatus includes an adjustable stand device for mounting a notebook or tablet computer comprising at least a base 100, a first member 200 mounted on the base 100, a second member 300 slidably coupled to the first member 200, and a laptop backboard cradle 400 mounted on the second member 300. Finally without removing the intermediate product from the mold and immediately after the predetermined time has elapsed, performing a second pressing of the intermediate food product between the stamp and the mold cavity at a higher force than that used in the first pressing until a final food product with a contour corresponding to that of the mold cavity is achieved. The input terminals are configured to receive a first, second and third phases of input AC power and at least one selected input terminal of the first, second and third input terminals is adjustable to alter a number of turns of the respective winding of the corresponding first, second or third coil on either side of the selected input terminal.
