20100321185 | DEVICE, METHOD, COMPUTER PROGRAMME AND SYSTEM FOR DETECTING IF AN OBJECT OR A PERSON CROSSES A LIMIT MARKED BY A MAGNETIC FIELD - A device for recognizing when an object or a person crosses a threshold that is marked by a magnetic field comprises a first magnetic field sensor that is designed to detect a first magnetic field component of the magnetic alternating field and to deliver an associated magnetic field sensor signal. The device comprises a second magnetic field sensor that is designed to detect a second magnetic field component of the alternating magnetic field. The device also comprises an evaluator that is designed to deliver information in response to a change in a phase relationship between the magnetic field sensor signal delivered by the first magnetic field sensor and a reference signal based on the detection of the second magnetic field component by the second magnetic field sensor, said information indicating that the object or person has crossed the marked threshold. | 12-23-2010 |
20110025471 | RFID transponder, in particular for assembly on metal and manufacturing method therefor - The invention relates to an RFID transponder comprising: an antenna, a chip comprising at least one transmission and reception circuit as well as a memory, a dielectric carrier element which is covered on a first surface at least sectionally with a structured first metallization and which is covered on a second surface disposed opposite the first surface at least sectionally with a second metallization, wherein the first and second metallizations are mutually electrically conductively connected, thereby forming the antenna, wherein the first metallization is structured such that it forms two electric terminals of the antenna arranged on the first surface of the dielectric carrier element, and wherein the chip can be or is electrically contacted via these two terminals and is positionable or arranged on the first surface and/or is positionable or arranged at least sectionally integrated into this surface, and an adaptation network at least partly formed by the structuring of the first metallization and adapting the input impedance of the antenna in a conjugate complex manner to the impedance of the chip. | 02-03-2011 |
20110272884 | TRANSPORT OF AN OBJECT ACROSS A SURFACE - A basic idea of the present application is that in case of determining a position of the object on the surface, it is possible to also use transport mechanisms for the transport of the object on the surface which leads to less reproducible transport movements as the regulation may be executed directly on the basis of the observed movement as compared to the desired movement. Embodiments using compressed air, magnetism and/or bending waves are described. | 11-10-2011 |
20130128876 | CONCEPT FOR COMBINING CODED DATA PACKETS - Concept for transmitting payload data from a transmitter to a receiver via a communication channel within a time interval, wherein channel-coded data packets are generated from the payload data, wherein each of the channel-coded data packets has packet core data corresponding to a packet identification of the respective channel-coded data packet, and wherein the packet core data is coded with a channel code of higher redundancy than the payload data. The channel-coded data packets are sent without any return channel to the receiver, which decodes packet core data of a first received channel-coded data packet of the time interval. If error-free decoding of the first channel-coded data packet fails, packet core data of at least one second received channel-coded data packet of the time interval are decoded to determine a suitable further channel-coded data packet for combination with the first channel-coded data packet to acquire, on account of the combination, an increased code gain for decoding of the payload data. | 05-23-2013 |
20130136152 | PASSIVE TEMPERATURE SENSOR - A passive temperature sensor with cordless measurement signal transmission includes: a coupling element that is implemented to draw electric energy from a magnetic or electromagnetic alternating transmission field; an energy rendering element that is implemented to provide an energy supply signal based on the drawn electric energy; a temperature measurement circuit that is implemented to generate, when supplied with the energy supply signal, a sensor alternating signal whose frequency depends on an environmental temperature; and a switching element that is implemented to change, based on the sensor alternating signal, a physical characteristic allocated to the coupling element to obtain an impact on the alternating transmission field based on the sensor alternating signal. | 05-30-2013 |
20130230060 | DATA TRANSMITTER AND DATA RECEIVER - A data transmitter for transmitting a data packet to a data receiver via a communication channel includes a generator for generating the data packet and a transmitter for transmitting the data packet.
