Abstract: The invention relates to a process to check the pairing of a Bluetooth Low Energy (BLE) transmitter with a BLE receiver, comprising the following steps: Transmitting to the BLE transmitter of a function for generating a sequence of data packets, each data packet generated in accordance with the function having at least one identification value, one major value, and/or one minor value, and at least two data packets of the sequence having different identification values, major values, and/or minor values; Sending, at intervals, by the BLE transmitter of the data packets of at least one sequence generated by the BLE transmitter in accordance with the function; Receiving, by the BLE receiver, of at least part of the sequence of data packets transmitted by the BLE transmitter; Checking, by the BLE receiver, of at least part of the received sequence for whether it correlates and/or agrees with the function; and, if it does correlate and/or agree; Generating by the BLE receiver of a pairing signal for the BLE tra

Abstract: Aspects of the innovations herein relates to a housing having a housing wall comprising a polymer including electrically conductive particles, wherein an inner chamber is provided in the housing, and is formed and enclosed by the housing wall and into which a mobile telephone may be inserted. In some implementations, the housing wall may be designed to attenuate a mobile radio signal of the mobile telephone, such as by ?3 dB, as compared to unobstructed propagation, on the side of the housing wall facing away from the inner chamber.
