Abstract: An inclination sensor is provided having a level that has a liquid and a gas bubble under a covering glass in a housing. A light source is arranged above the covering glass. The inclination sensor can be used to determine a direction and degree of an inclination with high accuracy and which is suitable for automatically aligning an apparatus provided with the inclination sensor. An arrangement is provided that has at least two light receivers arranged above the covering glass such that the light that is emitted from the light source and, in the case of a centered gas bubble, is scattered on the surface of the covering glass coming in contact with the gas bubble can be detected by the at least two light receivers. Different quantities of light can be detected by the light receivers when the gas bubble is not centered, and the light source and the light receivers are arranged on a chip substrate.

Abstract: A process is disclosed for transmitting serial data structures for information carrier identification systems (RF-ID systems), a transmission system working according to this process and an information carrier for contactless, electromagnetic transmission of serial data structures. The identification system has an interface (antenna) and an information carrier (transponder). The transmission process is essentially characterized in that a time-parallel data transmission and comparison between the data emitted by the interface and the data immediately sent back by the information carrier is carried out. The information data carrier has as essential components two appropriately sizeable receiving and emitting inductances and a multiplexer that is connected with a demodulator, a control logic and a non-volatile memory.
