An object of the present invention is to reduce the workload at the installation site even when the sealing material is in the form of a band. The margin requirement may be calculated while trading because the preferred system takes into account working orders to generate the margin requirement. The second chamber is provided with a second deformable membrane and with third and fourth gauges. The position of the golfer’s feet with regard to the golf ball can be reproducibly predetermined or adapted, respectively, using the positioning device. One implementation involves detecting road surface reflections, by receiving an image of a road in front of a vehicle from an image capturing device, determining a region of interest in an identified road in the image, and detecting road surface reflections in the region of interest. In one embodiment, the device includes an emulator to facilitate direct communication between an advanced host controller interface software driver and NAND host controller interface hardware.
