There is provided an optical component. The air inlet 20 extends from the housing 12 to communicate with an air intake port located at a vehicle location where fresh air is available. Specifically, at the sender side, a first message to a receiver is generated, wherein the first message includes a message text and a unique message identifier. In another embodiment, a decoding accelerator is controlled by providing commands to the accelerator via posted write operations and polling the accelerator to determine whether the command has been performed. By using the non-Gray code mapping, a performance improvement over such a system using only Gray code mapping may be achieved. Then a record extraction processor extracts relevant records on the basis of the record extraction criterion, and a record reformatting processor reformats them according to the record reformatting rule.
