A gripper for a contact lens comprises a gripper head having a bearing surface for the contact lens to adhere thereto. Signals sent from a receive node to a transmit node may acknowledge satisfactory signal receipt, or may requesting retransmission of data packets received in a corrupted state. In the electrical connecting position the mutually facing contact ends of the outer conductors are in touching contact. By exciting a specific mixture of gases, radiation is emitted at a combination of energies and intensities calculated to disrupt populations of unstable bonds in the carbon-doped silicon oxide film while leaving desirable bonds in the film unaffected. The latch includes a kick plate which is interlocked with a foot pedal whereby displacement of the kick plate permits release of the foot pedal to move from a latched position to an unlatched position, which pedal movement engages a linkage which opens a user access door in the container. When the data storage device is mounted to the support member, the fixing pole resists against the date storage device, and the hook is latched with the support member.
