Abstract: An interrupt system may include a medical bed having an upper frame and a lower frame, the upper frame movable relative to the lower frame. An interrupt system may include a sensor configured to detect a predetermined force between the upper frame and the lower frame, wherein the sensor is configured to stop movement of the upper frame relative to the lower frame when the predetermined force is detected by the sensor. In some embodiments, movement of the upper frame is reversed after stopping movement the upper frame. The sensor may include a membrane strip connected to the medical bed. A compressible layer may be positioned between the membrane strip and the cover. The sensor may include a hall effect sensor configured to monitor a rotation of one of a shaft and a gear of an actuator connected between the upper frame and lower frame.

Abstract: An x-ray tube includes a cathode adapted to emit electrons, a bearing assembly comprising a bearing hub, a target assembly positioned to receive the emitted electrons, the assembly having a target hub coupled to the bearing hub at an attachment face, wherein the attachment face comprises a first material compressed against a second material, and a first anti-wear coating attached to one of the first material and the second material and positioned between the first material and the second material.
