A new and distinct cultivar of Mandevilla plant named \u2018Sunparapibra\u2019, characterized by its upright and vining plant habit; relatively small glossy foliage; freely flowering habit; light pink-colored flowers; and long flowering period. One embodiment includes a vehicle position determining device, a wireless communications device, and a controller spaced apart from the at least one operable vehicle device and connected to the vehicle data bus so that the vehicle data bus extends from said controller to the at least one operable vehicle device. Further, the apparatus includes a detector including a plurality of light-sensing devices each configured to detect a light beam and configured to generate an output signal indicative of an intensity of light detected and a processor for determining the blood characteristic as a function of each generated output signal. When real-time positions have low qualities, this method calibrates them at a later time by using real-time positions both before and after them. Provision is made for accommodating legacy nodes that may have constraints in symbol rate or the number of carriers they can support.
