Abstract: A method for securely transmitting data from an IoT device to an application server via a telecommunication network, wherein a re-encryption server decrypts data encrypted by the IoT device and re-encrypts the decrypted data by an encryption key of the application server in such a way that the application server can obtain the data by decrypting the re-encrypted data. A re-encryption server is configured to enable secure transmission of data from an IoT device to an application server via a telecommunication network, and includes a cryptography means configured to decrypt data encrypted by the IoT device and to re-encrypt the decrypted data by an encryption key of the application server in such a way that the application server can obtain the data by decrypting the re-encrypted data. A system is configured for secure transmission of data from an IoT device to an application server via a telecommunication network.

Abstract: A transducer system with transducer and circuitry for applying a pulse train at a single frequency to excite the transducer. The transducer is operable to receive an echo waveform in response to the pulse train. The system also comprises circuitry for determining a time of flight as between a first reference time associated with the pulse train and a second reference time associated with the echo waveform.

Abstract: The invention relates to a control system and method for electric toy vehicles. The invention is suitable for vehicles which are controlled using a control element, which are actuated by an electric micromotor and which move on tracks comprising a guide groove which is flanked by electronductive tracks. Moreover, each vehicle is provided with a dynamic current collector and guide assembly comprising a guide flange which keeps the vehicle on the track. The inventive system comprises a transmitting control device which is associated with the above-mentioned control element in order to transmit signals in the form of digital waves which control the operation of the vehicle, a control device which receives the aforementioned signals and which is built into the vehicle, and actuation means which are connected to said receiving device. According to the invention, the signals are applied to at least one electronductive track which can be shared temporarily by at least two vehicles equipped with respective receivers.
