The invention relates to a data processing method for identifying a medical instrument (5) which is configured to be tracked by means of a medical tracking system (4), wherein the method is designed to be executed by a computer and comprises the following steps:acquiring relative position and/or movement data which comprise relative position and/or movement information describing a relative position and/or movement between a calibration tool (1), which comprises at least one supporting surface (2), and the medical instrument (5) which is in contact with the side or edge of the at least one supporting surface (2), respectively;acquiring geometry data which comprise geometry information describing at least one geometrical feature for a plurality of candidate instruments;determining, on the basis of the relative position and/or movement data and the geometry data, candidate data which comprise candidate information describing at least one candidate instrument from the plurality of candidate instruments, the at least one geometrical feature of which would allow the relative position and/or movement between the medical instrument (5) and the calibration tool (1).

An anti-piracy device for ships comprises a blocking device, such as a metal plate, to block an opening from the exterior to the interior of a ship, such as a window or porthole. The anti-piracy device also includes mounts, which are mounted permanently to the interior wall of the ship, to which the blocking device can be removably fastened, by nuts or the like. This allows the device to be installed when entering dangerous waters, but removed and stored when traversing safe waters.

An wind deflection apparatus (240), including: a fairing (242, 250) shaped to have a leading edge profile (606) that is configured to cooperate with a side profile of a console (206) to redirect an oncoming airflow laterally away from an occupant positioned behind the console; and a mounting apparatus (350) configured to secure the fairing relative to the console. A console (206) having the wind deflection apparatus. And a boat (202) having the wind deflection apparatus.

The instant invention describes an anti-biofouling structure for placement onto structures or surfaces that are exposed to aquatic environments. Embedded within the anti-biofouling structure are agents that can diffuse out of the structure and prevent the formation and/or accumulation of plant and animal species build-up that creates biofouling. The instant invention also describes a system for preventing biofouling of an object stored in an aquatic environment which includes the anti-biofouling structure, and a protective cover element constructed and arranged to fit various structures, such as boat propellers.

Disclosed is a lining for drives, such as sterndrives, of vessels has a housing that consists of two housing halves. The housing is secured on an adapter plate fastened to the vessel. A seal is provided between the housing halves. A seal that can be expanded by compressed air is arranged between the housing and the adapter plate. The housing halves are connected to one another by use of tension locks. The housing is secured on the adapter plate by use of tension locks. In the housing, a float-controlled bilge pump, from which a line leads to an opening provided in the upper area of the housing, is provided below.

A boat cover system includes a receptacle and a telescoping tent pole secured in the receptacle. The tent pole may include an outer tube selectively securable in the receptacle, an inner tube slidably mounted within the outer tube, and a linear actuator coupled with the inner tube and configured to displace the inner tube relative to the outer tube. With a boat cover positioned over the telescoping tent pole, the telescoping tent pole is displaceable between a retracted position and an extended position by the linear actuator such that the telescoping tent pole is configured to tension the boat cover in the extended position and to ease the tension in the retracted position.

A garboard drain plug system comprising an ergonomic grip which may aid in tightening and loosening the drain plug by hand without special tools. The garboard drain plug system may comprise a light ring which may surround a garboard, and thereby illuminate an area adjacent to, or surrounding, the garboard. Together, the ergonomic drain plug, garboard, and lighted garboard ring may act alone or in cooperation to provide a method of controlling communication of a fluid through a drain of a hull or transom of a boat or vessel.
