Abstract: The present invention relates to an oscillator arrangement, arranged for providing an oscillator output and phase noise detection and/or control of said oscillator output, the arrangement comprising a mixer (1) connected to a low-pass filter (2). The oscillator arrangement comprises a first oscillator (7) and a second oscillator (8), where the oscillators (7, 8) are inter-injection locked to each other by means of at least one coupling element (Q) in such a way that the oscillator output is acquired in quadrature automatically. The present invention also relates to a corresponding method.

Abstract: A lawn edge trimmer having a supporting structure (21) and an edge trimming assembly (10; 10'). The trimming assembly includes a frame (12) supporting a rotatable cutting knife (18), and a rotatable supporting wheel (30; 30') connected to the frame (12). An axis of rotation of the knife is parallel to an axis of rotation of the wheel. The wheel is supported by a lever (32; 32') rotatably attached to the frame, and may be latched relative to the frame (12). The lever (32; 32') is provided with a mudguard (41).
