Abstract: The present invention relates to an apparatus and a method for stimulating a person, wherein said apparatus comprises: at least one stimulation signal generator which generates a stimulation signal which is applied to said person; at least one detector for detecting a physiological signal derived from said person in response to said stimulation signal; and a monitoring unit which controls a safety switch to terminate automatically the application of said stimulation signal to said person, if a critical state of said person is recognized in response to the detected physiological signal.

Abstract: The invention relates to a device for localizing tracking bodies (10), comprising at least one tracking body which is placed inside a physiological structure, and a means which is situated outside of the structure and which consists of sensor clusters (20) in a sensor cluster arrangement (55) as well as a method for localizing and influencing the tracking body. The tracking body is provided in the form of a body which is characterized by a finite remanent magnetization with a variable magnetic dipole moment and an anisotropic magnetic dipole field resulting therefrom. The sensor clusters (20) are provided in the form of a plurality of gradiometer sensors (30) with a specific measuring geometry. Optionally, physical/chemical properties and/or a trajectory of the tracking body may be altered in a specific manner by an externally acting magnetic field (H) and/or physiological processes in the environment of the at least one tracking body.

Abstract: The invention relates to a device for the adaptation of in particular surgical instruments, such as pointing devices. Said adaptation device comprises a magnetic field sensor or the like, a receiver device for a surgical instrument and a locking option for said surgical instrument. Said receiver device, which is associated with the respective surgical instrument and exclusively adapted thereto, permits a precise positioning of said instrument in relation to the sensor by means of a locking device. Said locking device as well as the receiver device design prevent an unintentional loosening or a displacement of the surgical instrument in the receiver device. A time consuming recalibration of said magnetic field senor on assembling and disassembling the surgical instrument is thus avoided.

Abstract: The invention relates to a sensor device for detecting changes in location and position of a proband in a neuronavigation system which is used to carry out and support surgical interventions. Said device can be fixed to the head of the proband and the output signals are supplied to a system computer as correction data. According to the invention, a shaped tooth rack for receiving a fixing agent and a sensor capsule with means for detachably fixing to the tooth rack are provided. The shaped tooth rack is fixed in the oral cavity of the proband with the fixing agent, the sensor capsule being oriented towards the outside in the direction of the cheek so that the oral cavity remains essentially free.
