A lead assembly for placement in a coronary vessel of the heart, the coronary vessel having a pericardial wall portion and a myocardial wall portion. The first light-blocking pattern and the second light-blocking pattern are arranged alternately. The first pair of guide members is attached to the bottom side of the second module, and couples with the first pair of channel members. The conductive thermoset material is formable into one or more articles. In one embodiment, the methods further include encrypting the first key using a second key to create a second encrypted key, wherein the second key is available only to the storage system, and storing the second encrypted key and the first encrypted data as received, without having to decrypt and re-encrypt the first encrypted data. Hence, a liquid crystal display with no brightness or color non-uniformity can be manufactured.
