A computer-implemented system and method for the processing and presentation of aviation information is disclosed. The image capturing device includes: an image capturing section for capturing an image of a work range of the worker; and a communication section for transmitting, to the server device, at least one of the image captured by the image capturing section and generated information generated in accordance with the image. A generally sinuous shaped spacer rod sub assembly having spacer portions connected at junctures is provided. This ECL level pre-driver is used to build enough current and voltage drive capability to drive the high-current H-switch driver. A consumption device receiving such a data structure may verify the authenticity of the electronic signature and, if verification succeeds, decrypt the encrypted diverse content in the data structure. The top and bottom pieces can be fastened to one another, for example, using an adhesive or one or more mechanical fasteners.
