A motor vehicle chassis for a motor vehicle has an adapter element to join an aluminum crashbox to a longitudinal supporting beam. According to one embodiment of the present invention there may be provided, in an in-vivo device, at least an imager, an illumination source to provide illumination for the imager, an irradiation source to emit for example a light beam or a laser beam in a body lumen and a processor to calculate, based on image illumination parameter values, an estimate of the size of objects in a body lumen. A panel-receiving U-shaped channel is located on the opposite side of the leg, away from the rails. However, if the opacity bit is set to a transparency-indicating state, then a transparency level value is stored in at least one bit of each set of bits and the respective color level value is stored in other bits of each set of bits.
