In a method of driving a lamp using a lamp control circuit, the lamp control circuit comprises a communication circuit and a lamp driving circuit. The tool caddy includes a main tool storage unit having an upper opening into an interior and comprising a core section having a pair of side walls and a bottom wall extending between the side walls. The integrated circuit may further include an interconnect extending entirely through the semiconductor substrate and the dielectric layer, thereby electrically contacting the wafer substrate. The cardholder purchase information indicates that the cardholder purchased the offer. The measured eye diagram properties are then compared against the parameters. In order to enable such a device to change the orientation of slice images during the treatment in a simple and interactive manner, according to the invention adjusting means are provided on the part of the medical instrument which projects from the object to be examined in order to change the orientation of the slice images reproduced.
