Abstract: An apparatus provides signal links of M with N signal connections. A first stage has first switching matrices, wherein the first switching matrices are designed to establish at least one switchable signal link between each associated first signal connection and an associated second signal connection. A second stage has a second switching matrix with a size of N×M. In a sub-area of the second switching matrix the intersection points X2p,q that comprise switching elements are precise those that for N?M satisfy the conditions: p???=1i?1n??q (mod ni); 1?p???=1i?1n??ni and 1?q?M.

Abstract: An occupancy sensor has three layers. The bottom layer contains two electrodes, and a resistive element between the electrodes. The middle layer is a spacer. The top layer is a third electrode, divided into two parts. When a person sits on the sensor, both parts of the third layer contact the resistive element. This causes current to flow through all of the electrodes. Accordingly, occupancy can be detected by measuring current flow through the electrodes. The device additionally provides heating via the resistive element. The sensor can be arranged in a vehicle seat.
