In a mobile vehicle 1 having a vehicle body 2, a front wheel 3f, and a rear wheel 3r, the steering control wheel 3f can be steered by a steering actuator 8 about a steering axis Csf which is tilted backward. The porous core is preferably a sponge formed by freeze-drying a liquid suspension of the first bioabsorbable material. The substrate also interfaces with the conductors of two modular ports of the connector, and is removable from the housing such that an insert assembly of a different electronics or terminal configuration can be substituted therefor. A method inputs energy to andor outputs energy from the first coil and a power supply system utilizes the device and method. The light illuminates the patient’s tissues proximate the blades. The second hollow profile has at least two planar sides that press against the ends of the first hollow profile resulting from the cutting and bending.
