Abstract: A motorcycle with a swing arm element pivotably coupled to a holding element of the motorcycle via a rotary bearing is provided with a tensioning element. The motorcycle also includes a pulling member which engages two gear elements which are each spaced from the rotary bearing in a torque-transmitting manner. The first gear element is rotatably mounted separately from the swing arm element, and the second gear element is rotatably mounted on the swing arm element. The tensioning device for tensioning the pulling member is mounted rotatably and/or in an axially displaceable manner relative to the two gear elements on the swing arm element or on a frame of the motorcycle. The tensioning device includes at least two levers pivotable relative to one another, and a tensioning element which biases the levers against the pulling member to maintain consistent tension in the pulling member.

Abstract: A collision protection device on a motorized bicycle includes a catching element which is securely mounted on a frame of the motorized bicycle. The catching element includes a receptacle which is delimited by two guide sections and is open in the direction towards a front wheel of the motorized bicycle. The free ends of the guide sections pointing in the direction of travel are arranged such that they are always at a distance from the front wheel during normal riding but, in the event of a front-end collision in which the front wheel impacts on an obstacle, the front wheel is pushed into the receptacle between the free ends of the guide portions towards the frame of the motorized bicycle.

Abstract: A motor vehicle stores a first one-way hash of a password and an encrypted value from a second one-way hash of the password. A method for authenticating a device with respect to the vehicle includes the following: a PACE procedure is carried out so that the device and the motor vehicle determine the same session key; the motor vehicle generates a communication key on the basis of the session key and the encrypted one-way hash; and the device generates the communication key based on the session key and the second one-way hash.

Abstract: A driver assistance system has an emergency stopping function for a motor vehicle. The driver assistance system is designed to perform an automated lane change from a first lane to a second lane when the emergency stopping function is triggered. The driver assistance system is further designed to determine at least one road characteristic and/or at least one vehicle interior characteristic and, based on the determined at least one road characteristic and/or the vehicle interior characteristic, to decide whether to execute the lane change.

Abstract: A test device for testing a detection device includes a reflection element with reflective surface where the reflective surface is a radar reflective surface and/or an ultrasound reflective surface. The reflection element is movable by a drive device periodically back and forth in a translational movement along a movement axis with respect to a housing of the test device. A movement of the reflection element produces a relative speed unequal to zero of the test device with respect to the detection device.

Abstract: A method configures a workpiece-related workpiece holding device for press automation. At least one workpiece-specific holding element of the workpiece holding device is configurably secured to a support of the workpiece holding device in at least one degree of configuration freedom. The method has the steps of (a) imaging a real image of the at least one workpiece-specific holding element on a display device and (b) outputting configuration information relating to the at least one workpiece-specific holding element on the display device, the configuration information including at least one piece of reference information relating to a relative reference orientation and/or a relative reference position of at least one region of a workpiece-specific holding element relative to the support.

Abstract: A three-plate pressure die casting mold for producing at least one metallic die casting part by die casting a metal melt, includes first, second and third mold parts and at least one mold cavity as well as a sprue system. In the third mold part there is at least one spring-loaded pressure element which, when opening the die casting mold, presses the sprue produced in the sprue system against the first mold part, whereby the sprue is retained and tears off from the die casting part in a defined manner. A method for pressure die casting using the three-plate pressure die casting mold is disclosed.

Abstract: A method for determining a correctness of an actually received timestamp is provided. A communication network includes a master clock, a first ECU having a first slave clock, a validator having a second slave clock, and a first communication bus. The first ECU uses a first communication standard having a deterministic scheme. The method includes synchronizing, at the first ECU, a time of the first slave clock to a global time of the master clock, synchronizing, at the validator, a time of the second slave clock to the global time of the master clock, predicting, at the validator, a timestamp to be received in an actual communication cycle from the first ECU based on the deterministic scheme of the communication standard used by the first ECU, and comparing, at the validator, the predicted timestamp with the actually received timestamp from the first ECU.

Abstract: A device operates an electrical energy store for supplying components of an electrically operable motor vehicle, wherein operating limits are defined in each case for one or more characteristic variables of the energy store. A control unit prevents the operating limits from being exceeded during normal operation of the energy store. The device has an interface for receiving a user-side request message from an apparatus, the request message including change information about an intended shift in the operating limit of at least one of the characteristic variables.
