An optical code scanner is presented that includes image capture technology to read optical codes. A plurality of processors are used to implement a virtual queue, for controlling a rate of flow of data on the network. In at least one wait state, the positioning device is moved such that the examination segment is situated in the optimal measurement volume of the MR spectrometer. At least one processor compares the outside temperature at at least one location and at least one point in time to information reported to the remote processor from the thermostat. The mirror assembly may comprise an actuator configured to change an orientation of a mirror with respect to another mirror.
