Abstract: Systems and methods combine a test signal with a wanted (downlink or uplink) signal at an input of a duplexer of a communication device, and receive the test signal at an output of the duplexer. The test signal may include a radio frequency signal having less power than the wanted signal to avoid interference, or a digital signal that is added to or extracted from the wanted signal when the wanted signal does not have a radio frequency. A processor of the communication device causes the duplexer to operate in a tuning state (e.g., to transmit signals having a transmission frequency and receive signals having a receive frequency). The measurement system determines a difference or ratio in power between the test signal at the duplexer output and the duplexer input, and adjusts the tuning state based on the difference or ratio (e.g., to decrease or minimize the difference or ratio).

Abstract: The invention relates to a method for producing a bodywork component of a motor vehicle that has first been shaped and is then thermally surface-treated, said method comprising iterative simulated steps with variable geometric data of tools that are used in the shaping process. According to the invention, a continuous check verifies whether the expected geometric data of the component lies within the permitted tolerance range of the nominal geometric data of the component. If this is not the case, the geometric data and the generation of corrected tool geometric data is modified. This takes place in two stages, the first stage for the shaping steps and the subsequent stage for the process steps of the thermal surface treatment.
