Disclosed is a safety device for ensuring safety of occupants in a vehicle. The varying amounts of energy may be applied via one or more conducting elements, which include an outer conductor and an inner conductor disposed within the outer conductor, a distal end of the outer conductor and the inner conductor defining the varying patterns. The embodiment is configured to facilitate social sharing functions including: inviting users to download the payment application, sharing a contact list among a plurality of payment application users, inviting users to chat from the payment application, and updating a user profile in the client messaging application by the payment application. The roof’s ribbed, single-ply construction provides for a stronger roof with a plurality of storage compartments for a plurality of accessories within the ribs. To provide a stable mode locking and improve power stability and beam stability in an ultrafast laser such as a femtosecond laser, optical mounts which have mounted thereon optical parts of a diode pumping unit are mechanically engaged using bars of low thermal expansion coefficients and form a pumping module, and the pumping module is maximally separated from a laser platform or case.
