In a diagnostic ultrasound apparatus, an ultrasound pulse signal is transmitted two times in each of the rasters on a region to be scanned. Wires electrically couple the battery charging apparatuses to a charger unit. The amount of protein displaced from a specific resin by a defined concentration of displacer is determined by monitoring the supermatant for the protein. The preservative transfer device is in communication with both the storage container and the applicator device to transfer a preservative stored in the storage container to the applicator device. The connection system has at least one movable locking element which locks in the locking position the hydraulic connection associated with it, and releases the connection after displacement in the open position. The operating system translates typed data objects from a first format to a second format if the application sending the object and the application receiving the object utilize different formats.
