    摘要: Forward voltage drift in a probe system for the characterization of a light-emitting wafer is virtually eliminated by directing compressed air to the probe so as to ensure that the exact same temperature conditions exist during repeated measurements of the wafer. In one embodiment of the invention, an air flow at room temperature is used, either continuously or intermittently. In another embodiment, the temperature of the probe is controlled by flowing a liquid or a gas through micro-channels built into the probe. In yet another embodiment, the probe is connected to a solid-state Peltier cell that is computer-controlled to maintain the probe's temperature at a predetermined set-point. A temperature-controlled chamber or a thermal reservoir enclosing the probe could be used as well. The results obtained showed remarkable repeatability.

    摘要: A signal transmitter contains at least one first luminous element, at least one second luminous element and an interface for connecting the signal transmitter to a signal box. A drive device is connected between the interface and the at least two luminous elements and the drive device is configured in such a way that, in the case of a switch-on signal coming from the signal box for the second luminous element, the drive device controls the activation of the luminous element depending on the signaling state of the first luminous element.
