Embodiments of the present invention relate to methods and systems suitable for de-convoluting a convoluted spectrum, such as by way of example, data obtained from a mass spectrometer. A surface of each wing tip device has a recess that reduces flow impact at a junction of the wing and the wing tip device. A normalized working range for an array of elastic contacts of the interposer can be about 0. Thereafter, a combination of the captured video and alphanumeric text contemporaneously with the video is recorded on a selected medium. An alternative embodiment of the invention is an underwater light in which a high intensity discharge light and ballast is completely installed into the above-described view port.
