Method and arrangement for generating an output clock signal with an adjustable phase relation from a plurality of input clock signals. A method and an arrangement are provided for generating an output clock signal (o), in which a plurality of input clock signals (s, c) that have a predetermined phase relationship to one another, are weighted with respective weighting factors (A, 1-A), and in which the weighted input clock signals (s′, c′) are added in order to generate a summated clock signal (i). The summated clock signal (i) is integrated in an integrator (8) and optionally amplified in order to generate the output clock signal (o). An output clock signal (o) with an adjustable phase relation can be generated with such a method and such an arrangement, in which the requirements placed on the input clock signals are less stringent.

A surgical resection guide enables a surgeon to resect a femoral neck, during a hip arthroplasty procedure, such that a femoral prosthesis can be implanted within a patient to preserve or closely approximate the anatomic center of rotation of the hip. The guide is able to be used for left or right hip arthroplasty procedures, with either anterior or posterior surgical approaches.

An apparatus interfaces a first circuit using a first supply voltage and a second circuit using a second supply voltage different from the first supply voltage. The apparatus includes a driver circuit having a driver network comprising driver supply voltage terminals connected to controllable switches. The controllable switches include resistive elements or are separated from resistive elements. A receiver circuit has a receiving network comprising a resistive element and receiver supply voltage terminals and a connection line connecting the driver circuit and the receiving circuit. The controllable switches have two switch configurations, a first switch configuration resulting in a high voltage on the connection line and a second switch configuration resulting in a low voltage on the connection line.
