Abstract: A system described herein includes a first lens, a first image stabilization unit and a first image plane. When seen from the first lens in the direction of the first image plane, the order in which the elements are arranged along a first optical axis is as follows: first lens, first image stabilization unit and first image plane. The first image stabilization unit has at least one first inlet surface and at least one first outlet surface. The first inlet surface is oriented towards the first lens. The first outlet surface is oriented towards the first image plane. Furthermore, the first outlet surface is spaced apart from the first image plane in a range of 1 mm to 20 mm.

Abstract: An optical system for imaging an object has at least a first objective, at least a first image stabilizing unit and at least a first eyepiece, wherein, as seen in the direction of the first eyepiece from the first objective, the first objective is arranged first along a first optical axis, then followed by the first image stabilizing unit and then followed by the first eyepiece. The first image stabilizing unit is rotatably mounted in cardan-joint fashion about a first hinge point, and the first hinge point is arranged between the first objective and the first eyepiece. The optical system is distinguished by virtue of the fact that the first image stabilizing unit comprises a first lens unit and at least a further optical element, wherein the first lens unit and the optical element are arranged such that the first lens unit is, together with the optical element, rotatably mounted in cardan-joint fashion about the first hinge point.

Abstract: A circuit arrangement is disclosed which detects a signal pauses in an audio signal, The audio signal is amplified, rectified, and then sent to a control unit. The control unit periodically sets the output of the rectifier to a predetermined level below a threshold level. The control unit then waits a predetermined period of time and determines whether the signal at the output of the rectifier has exceeded the threshold. If is does not, a signal pause has occurred.
