Abstract: An adaptor for securing a second object includes an anchoring part and an adjustment part, wherein the anchoring part includes a distally facing anchoring surface and a proximally facing first control surface. The adjustment part has a distally facing second control surface positioned to abut against the first control surface. The anchoring part and the adjustment part define a common axis that is not perpendicular to the z direction, wherein the first control surface and possibly also the second control surface is/are helical with respect to the axis. Thereby a relative z position of the adjustment part with respect to the anchoring part is defined by the relative orientation of the adjustment part with respect to the common axis while the second control surface abuts against the first control surface.

Abstract: An adaptor is secured to a first object. The adaptor includes an anchoring part and an adjustment part. The anchoring part includes a distally facing anchoring surface and a proximally facing first control surface. The adjustment part has a distally facing second control surface positioned to abut against the first control surface. The first control surface or the second control surface or both is/are helical. Thereby a relative z position of the adjustment part with respect to the anchoring part is defined by the relative orientation of the adjustment part with respect to the common axis while the second control surface abuts against the first control surface.

Abstract: A system for establishing an anchorage in an operation site of a human or animal patient with the aid of a material having thermoplastic properties and vibration energy. The system includes a transmitting piece connected or connectable to an energy source for generating vibration energy, and a housing with an opening. The transmitting piece is arranged moveably within the housing, the opening being adapted to the transmitting piece for a distal portion of the transmitting piece to be able to protrude from the opening. The system also includes a driver being activatable for exerting a compression force on the transmitting piece, and a thermoplastic element arranged to be compressible between the transmitting piece and a counter element by the compression force. Furthermore, the system is equipped for shock-free initial positioning and pre-pressing of the transmitting piece against the thermoplastic element.

Abstract: An EEG headpiece includes an array of electrode pins, each electrode pin extending between a proximal end, formed by a proximal end face, and a distal end and including a conducting electrode and a thermoplastic material. The thermoplastic material is arranged at least around a periphery of the electrode pin or is pressable from a hollow space to the periphery. Each electrode pin is equipped for the transmission of energy, especially mechanical vibration energy, from the proximal end face to the thermoplastic material to liquefy at least portions of the thermoplastic material from a solid state to a flowable state, whereby the thermoplastic material is capable of flowing into structures of a tissue portion surrounding the periphery and of forming, after re-solidification of the thermoplastic material, an anchoring of the electrode pin in the tissue portion.

Abstract: A device for measuring the oil level in the sump of an internal combustion engine. A resistive wire probe extends into the oil contained in the sump. The voltage across the terminals of the probe will vary according to the immersion of the probe in the oil and such voltage is transmitted to a galvanometer in the form of an oil level gauge for indicating the level of the oil to the driver. In order to prevent termination of the signal to the oil level gauge when the engine is started and pumps the oil out of the sump, a timer circuit is provided to continue the signal to the oil level gauge for a predetermined period of time after the ignition switch is closed.
