Abstract: A computer-implemented method or protecting a machine-learning model against training data attacks is disclosed. The method comprises performing an initial training of a machine-learning system with controlled training data, thereby building a trained initial machine-learning model and identifying high-impact training data from a larger training data set than in the controlled training data, wherein the identified individual training data have an impact on a training cycle of the training of machine-learning model, wherein the impact is larger than a predefined impact threshold value. The method also comprises building an artificial pseudo-malicious training data set from the identified high-impact training data and retraining the machine-learning system comprising the trained initial machine-learning model using the artificial pseudo-malicious training data set.

Abstract: The invention relates to a wave generator for a strain wave gear, said wave generator in a main portion having a bearing seat for a radially flexible roller bearing. The wave generator is distinguished by having a cone portion that adjoins the main portion in the axial direction and tapers off in a direction away from the main portion.

Abstract: A microwave oven including an oven housing defining an oven chamber, a magnetron in the oven housing, and three alternative paths along which electrical power may be supplied to the magnetron, the three alternative power supply paths including an alternating current (AC) power supply path that enables the oven to be electrically connected directly to AC mains, a first direct current (DC) power supply path that enables the oven to be electrically connected directly to an electrical socket in a motor vehicle, and a second DC power supply path that enables the oven to be electrically connected directly to a battery.

Abstract: A technique for imaging relative elastic properties combines B-scan and power Doppler signals to produce images of relative vibration amplitude. A method for imaging relative elastic properties of tissue includes vibrating an area of tissue of interest and capturing a power Doppler image of at least part of the vibrating tissue.

Abstract: A handle for a medical instrument comprises a first connecting means for connecting a shaft of said instrument of said handle, said shaft defining a longitudinal axis of said instrument. The handle further comprises a second connecting means for connecting a force transmission element of said instrument to said handle, said second connecting means being movable relative to said first connecting means for moving said force transmission element relative to said shaft for moving at least one tool disposed at the distal end of said shaft. The handle further comprises a first grip element and a second grip element, said first grip element and said second grip element being movable relative to each other, at least one of said first grip element and said second grip element being operatively connected with said second connecting means.

Abstract: What is described here is an instrument having a shaft element carrying an engaging element disposed on the distal end thereof, which is operated via a proximally disposed actuator element which is integrated into a handle for being mobile in such a way that the angle enclosed by the axis of said handle and by the axis of said shaft element may be varied. The invention is characterized by the provision that the handle is connected to the shaft element via a universal joint.

Abstract: A medical handling device, in particular for endoscopic applications, has a distally arranged medical instrument, a proximally arranged handle which has a grip part that can be gripped with the hand, and further a shaft part arranged between instrument and handle. It is proposed that the grip part gripped by a human hand can pivot relative to the shaft part about both the volar flexion axis and the dorsal flexion axis of the wrist, with no change occurring thereby in the position of the shaft part.

Abstract: Disclosed is an endoscopic cutting device for severing tissue, such as organs, parts of organs or the like, havinga cutting tool, which is attached at the distal end of said cutting device and which is provided with a cutting blade, andan actuating unit which is used to operate said cutting tool and which is attached at the proximal end of said device.The invented device is distinguished by the cutting blade being disposed approximately parallel to a longitudinal unit which can be varied in length.
