Abstract: A motor vehicle has a display unit, which is arranged on an inside of a vehicle roof. The display unit has a permanently integrated imaging device, which in particular cannot be detached by a user, and a reflector device that can be swivelled relative to the imaging device. The reflector device is arranged in such a way that the image generated by the imaging device is visible via the reflector device to a vehicle occupant, in particular one who is located or seated in front of the reflector device. The display unit and the imaging device—apart from the swivelling reflector device—are arranged substantially parallel to the inside of the vehicle roof. When the reflector device is not in use, it is also arranged substantially parallel to the inside of the vehicle roof.

Abstract: A method for checking the equality of multiple intermediate results from multiple redundant calculations using multiple identical application software instances. The processing of the same input data is monitored by a program flow control. This program flow control is used to check the equality of the intermediate results. In this process, an intermediate key in the program flow control can be modified such that the program flow signature is correct only if the intermediate results to be checked are equal. A system for checking the equality of multiple intermediate results from multiple redundant calculations, a computer program, and a machine-readable storage medium, are also described.

Abstract: A method for forwarding data from a plurality of data sources to a data sink. The method includes forwarding data, which were received from a first data source and forwarded from a comparison device, to the data sink by a monitoring device before the monitoring device has received control information, which indicates a result of a comparison of the data received from the first data source with data received from one or more second of the data sources, from the comparison device; and signaling a fault state to the data sink if the monitoring device has not received the control information, which indicates a result of the comparison, from the comparison device within a fault detection time after forwarding the received data to the data sink, or if the control information indicates a negative result.

Abstract: A device and method for intravascular treatment of atherosclerotic plaque prior to balloon angioplasty which microperforates the plaque with small sharp spikes acting as serrations for forming cleavage lines or planes in the plaque. The spikes may also be used to transport medication into the plaque. The plaque preparation treatment enables subsequent angioplasty to be performed at low balloon pressures of about 4 atmospheres or less, reduces dissections, and avoids injury to the arterial wall. The subsequent angioplasty may be performed with a drug-eluting balloon (DEB) or drug-coated balloon (DCB). The pre-angioplasty perforation procedure enables more drug to be absorbed during DEB or DCB angioplasty, and makes the need for a stent less likely. Alternatively, any local incidence of plaque dissection after balloon angioplasty may be treated by applying a thin, ring-shaped tack at the dissection site only, rather than applying a stent over the overall plaque site.

Abstract: A cage can be positioned around a medical balloon, such as an angioplasty balloon, to assist in a medical procedure. The cage can include a plurality of strips, each extending between a set of rings including first and second rings. As the balloon expands, the first and second rings move closer together and allow the strips to expand outward. The cage may have wedge dissectors on the strips.

Abstract: A serration balloon can have a number of different components and can be made in a number of different manners. One or more longitudinally extending members with periodic raised wedges can be attached to a medical balloon. They can be attached with a fiber coating, a polymer coating, or other methods. A polymer matrix can be used to bond the longitudinally extending member to the surface of the balloon. The fiber coating can be, for example, a thread or mesh that secures the longitudinally extending member to the balloon. The medical balloon can be an angioplasty balloon, such as an off-the-shelf angioplasty balloon.

Abstract: A method for checking a processing of payload data. The method includes processing the payload data and metadata by a sequence of data processing blocks. An adjustment value is ascertained for each data processing block as a function of a thereto-supplied payload data version so that, if the thereto-supplied metadata version is correctly processed by the data processing block to form a respective processing result, the processing result, after having been adjusted according to the adjustment value according to a specified adjustment rule, is equal to a value assigned to the data processing block. Each data processing block processes the metadata version supplied to it, and the next metadata version is derived from the supplied metadata version as a function of the processing result adjusted according to the adjustment value according to the specified adjustment rule, and checking whether the payload data have been processed correctly.

Abstract: A barrel having a dispensing device for dispensing a fluid, having a fluid reservoir for receiving the fluid, a carrying device with a carrying handle for carrying the fluid reservoir, wherein the carrying handle is movable relative to the fluid reservoir, a valve which is configured to release the fluid from the fluid reservoir when in an actuated state, and a spout which can be connected to the valve for dispensing the fluid released out of the valve. In a connected state in which the spout is connected to the valve, a relative movement of the carrying handle relative to the fluid reservoir leads to an actuation of the valve, while in a non-connected state in which the spout is not connected to the valve, the relative movement of the carrying handle does not lead to actuation of the valve.
