This method for carrying out the flexible demodulation of data modulated following an amplitude modulation in quadrature is used in a communications system employing a code division multiple access technique and an optical frequency division multiplexing using non-binary spread codes. The method utilizes a pattern of color patches, a color space and color difference metrics to analyze color changes which correlate to the amount of halo. The infusion device preferably comprises one or more infusion needles disposed within and implanted along with one or more housings adjacent the patient’s left and right corpora cavernosa. The first magnetic domains correspond to first data and the second magnetic domains correspond to second data. A message to the request message is transmitted based on the determinations and the decision. The electronic device may also include a latching mechanism including a slider configured to slide along at least one of the lid and the first side for latching the lid at the interior side.
