Abstract: The present invention relates to a device for cutting and aspirating tissue from the human or animal body, in particular for use in vitrectomy, epiretinal membrane peeling, etc., with an outer tube (1), and with an inner tube (2) which is movable to and fro and concentrically in the outer tube (1) with slight play, wherein the outer tube (1) is closed at the free end and has, near the free end, at least one lateral opening (3) with at least one inner cutting edge (5), wherein the inner tube (2) is open at the free end and there has an outer cutting edge (4), and wherein the cutting edges cooperate in a cutting action during the movement of the inner tube (2) relative to the outer tube (1), advantageously characterized by a shaping measure in or on the outer tube (1) and/or in or on the inner tube (2), whereby the inner tube (2), at least in the area of the lateral opening (3), runs in the outer tube (1) with at least slight pretensioning.

Abstract: The invention relates to a method for anonymizing the communication of mobile terminals which permit speech communication, using an anonymizing network which comprises a series of routers and which has at least one access node, wherein each mobile terminal establishes a connection with at least one access node, comprising the following steps: signing the mobile terminal onto the network via an access node; preparation of an identity in the network; communication via the anonymized network, wherein the network selects different random routes through the network for communication, so that back-tracing is prevented and wherein communication is encrypted.

Abstract: A method and device to analyze the security of a mobile terminal having application and baseband processors are described. Various information may be acquired by baseband and application monitor applications running on the mobile device including, for example, information about transmission channels, protocol transmissions, and/or data transmission volumes. Information about power consumption may also be acquired. The monitor applications may also measure response times to service requests as well as monitor various aspects of running applications including status, time/duration, inputs or outputs, and/or inputs from a user via a User-Interface. Information may also be acquired about the configuration of the audio path to determine which component or application is using the microphone.

Abstract: The invention relates to a method for operating a heated liquid bath heated by a heating device, particularly an electric resistance heater, particularly for monitoring overheating and/or a decrease in the liquid level, wherein by means of a temperature sensor an actual temperature is determined and, as a function of the actual temperature measured with the temperature sensor, an alarm and/or control signal is emitted, wherein by means of the temperature sensor the actual temperature of the heating device or in the region of the heating device is determined. The invention further relates to a device for carrying out said method.
