    • For determining a signal response characteristic of a device, a first signal is varied with a first function of time and simultaneously a second signal is varied with a second function of time, wherein the first function is different from the second function. The first and second signals are coupled to the device, wherein the device is exposed to a time-dependent disturbance signal. A signal response is received from the device in response to the first and second signals and the time-dependent disturbance signal. The signal response characteristic is derived by analyzing the received signal response in conjunction with the first and second signals, or a signal derived therefrom, and at least partially removing the time-dependent disturbance signal using the received signal response and the first and second signals, or a signal derived therefrom.

    • The invention relates to a method for interferometric absolute distance measuring by a frequency modulation electromagnetic radiation on at least one measurable target and for subsequently receiving a retransmitted radiation with a heterodyne mixture, wherein the radiation is guided in a parallel direction via a reference interferometric length. In such a way, a first digitized interferogram of the radiation retransmitted by the target and a second digitised interferogram of the radiation guided on the reference length are obtainable at a reception. According to phase progression data of the second interferogram, a virtual interferogram or a phase progression thereof is synthesized and the distance determination is carried out by comparing the progression face data of the first interferogram with the progression face data of the virtual interferogram.

    • An electronic assembly may be contained in a label that performs time-temperature integration (TTI) and indicates that time and/or temperature levels have been reached that may compromise the quality, shelf life, or safety of the item to which the label is affixed. The label may be used on a wide variety of objects that require careful handling in terms of temperature and/or time elapsed before use. The labeling system includes circuitry that measures and calculates, and indictor(s) that signal that the time has come for discounted sale, and, later, that the time has come for disposal rather than sale. Optionally, the circuitry may act as an “over-temperature alarm” system, to measure, calculate, and indicate when a one-time temperature violation has occurred that is of such a magnitude that the item is immediately considered compromised or spoiled. The label may take the form of a flexible, disposable label that is typically powered by a small battery. Methods may include providing a temperature-variable oscillator or time-base, counting cycles of said oscillator within a logic circuit to determine when one or more preset total cycle counts is/are reached, and signaling when said total cycle count(s) is/are reached. Extra sensing, time-keeping, memory storage, and/or communication interface circuits may be incorporated to augment the electronic assembly's and method's capabilities.
