Among other disclosure, a computer-implemented method for business process reporting includes receiving, at a server device, a first identifier of a business document, the business document being an instance of a business document type and having a first timestamp. The antireflection structure includes an area where a height of each of the raised portions is relatively low and a depth of each of the recessed portions is relatively shallow, and an area where a height of each of the raised portions is relatively high and a depth of each of the recessed portions is relatively deep. The connecting section is made of a ferromagnetic material, and electrically connecting between the first ferromagnetic layer and the second ferromagnetic layer. Pivoting the seatback forward about the rear bracket causes the connecting member to collapse the linkage rearward to a stowed position. The shielding arrangement, at least partly made of x-ray blocking material and provided for blocking, scattering andor reflecting x-rays is arranged, at least partly, in a space between the x-ray source and collimator. Heat generated by the separable contacts is transferred away from the separable contacts, through the housing and the thermally conductive mounting element, and into the thermally conductive panel member.
