Abstract: A medical head holder includes at least two opposing engagement members configured to engage the head of a patient, a frame, connector and coupling members, and a force applicator. The frame includes first and second frame sections which are displaceably coupled with each other, wherein each frame section supports at least one of the engagement members. The connecting member guides the first and second frame sections for displacement relative to each other, and selectively detachably fixes the frame sections with each other. The coupling member is selectively fixed to the second frame section and displaceably couples the second engagement member with the second frame section. The force applicator is detachably coupled to the second frame section and acts on the coupling member so as to cause the second engagement member to be displaced and/or fixed relative to the second frame section.

Abstract: A method of manufacturing a transfer assembly for transferring articles from a first moving carrier to a second moving carrier is provided. The method comprises providing a programmable motor and a motor control system. The motor control system and the programmable motor define an excitation frequency. The method comprises providing a carrier member comprising a housing comprising a wall and shifting a natural frequency of the carrier member by forming the wall with a first carbon fiber layer having a first fiber orientation extending in a first direction and with a second carbon fiber layer having a second fiber orientation extending in a second direction that is different than the first direction. The shifting the natural frequency establishes the natural frequency of the carrier member to be at least 1.1 times greater than or at least 1.1 times less than the excitation frequency.

Abstract: An apparatus for transferring one or more articles from a first carrier moving at a first speed to a second carrier moving at a second speed that is different than the first speed is provided. The apparatus comprises a programmable motor and a carrier member operably engaged with the programmable motor. The carrier member comprises a housing comprising a wall and an outer surface configured to receive the one or more articles from the first moving carrier in a receiving zone and configured to deposit the one or more articles onto the second moving carrier in an application zone. The wall comprises carbon fiber. The programmable motor is configured to move the outer surface of the housing at a third speed through the receiving zone and at a fourth speed through the application zone.
