An organic electroluminescent device comprising a pair of electrodes and at least one organic layer between the pair of electrodes, wherein the organic layer contains at least one compound represented by the formula, preferably by the formula and more preferably by the formula as defined herein. The natural vibration frequencies of the vehicle’s systems are determined and correlated with a range of possible braking regimes implemented by an on-board automatic brake control, such as an anti-lock braking system. State dependent content in the electronic document is identified. Thus, the pre-buffer level shifter can correctly drive the output buffer made of thin oxide MOS transistor devices, increase the operating speed and ensure the reliability thereof. The organ-stabilizing element is supported on a stacked structure of successive ball elements and rings that can be selectively flexible or rigid in response to tensioning of a flexible cable within a central bore of the structure. A simulated crab body and legs are attached to the lure through perforations and are removable.
