Abstract: The disclosure relates to medical devices and methods of manufacturing medical devices. An orthopedic screw includes an inner core member having a head having a first outer diameter, a tip having a second outer diameter, and a body extending between the head and the tip and having a third outer diameter that is less than the first outer diameter and the second outer diameter. An outer body member is disposed circumferentially around the body of the inner core member and defines an outer body member external thread. The tip of the inner core member can define an inner core member external thread that forms an interrupted thread with the outer body member external thread.

Abstract: A method and a device for starting a machine, in particular, a printing press, using a sensor or sensor field which emits a start signal during the approach of a part of the body of a machine operator. According to the method, the machine is automatically started if the start signal appears twice consecutively and if the following additional conditions, automatically checked by a machine controller, are met: No start signal is present within a first predefined time period following the instant of the first appearance of the start signal in a predefined time interval, and the start signal reappears within a second predefined time period following the first predefined time period. The device includes a proximity- or touch-sensitive operating surface, which has a first partial surface having the function of a machine starter and second partial surface, which blocks the function of the first partial surface for a predefined period of time in response to proximity or contact.
