Patent number: 6484221Abstract: A network bus for interconnecting a plurality of medical devices is described in which the devices are provided with modules adapted to communicate along the bus. Some of the devices are capable of assuming control over the bus with network master modules. A self-configuring capability is provided with which several network master capable medical devices automatically determine which network master is to take over control over the network bus and each individually is capable of controlling and operating the network. Each network master capable device has an extended network management module with which automatic master selection is achieved. This is done by monitoring or observing network communications for particular objects. Once such an object has been detected, a network master capable device is automatically selected to take over control on the basis of its priority.Type: GrantFiled: October 1, 1999Date of Patent: November 19, 2002Assignee: Storz Endoskop GmbHInventors: Andreas Lorinser, Andre Wetzel, Andreas Bayer, Pavel Novak, Klaus M.

Patent number: 6275786Abstract: The invention refers to a device for monitoring the application of a neutral electrode in unipolar HF surgery, having an impedance sensor with a resonant circuit comprising a secondary coil of a transformer and HF input capacitors of preferably two partial electrode surfaces. The impedance sensor detects the transient impedances of two partial electrode surfaces connected in series with the patient's tissues by application of a patient auxiliary current and is moderated by the transition impedances. The invention is characterized in that the resonant circuit is excited by alternating voltages of variable frequencies in the range of a resonant frequency, and in that a peak value detector is provided which detects an alternating voltage peak value at the resonant frequency. The disclosed device excites the resonant circuit in such a manner that a faultless measurement of the transition impedance at the level of the patient's tissues is made possible.Type: GrantFiled: December 22, 1999Date of Patent: August 14, 2001Assignee: Storz Endoskop GmbHInventor: Felix Daners
