Abstract: A computer-implemented method for securely transferring a secret from a source computing component to a target computing component, wherein the source computing component and the target computing component are part of a secure computing environment is disclosed. The method comprises upon the source computing component receiving from the target computing component a signed attestation document, verifying, by the source computing component, an authenticity and content of the attestation document, and upon a successful verification of the authenticity and the content, transferring, by the source computing component the secret to the target computing system. Thereby, the attestation document is attesting that the target computing component is compliant to an update governance rule.

Abstract: A cassette filter including a plurality of filter media packs, a frame for receiving the filter media packs, and protective grids. Two filter media packs in each case are arranged in a v-shape, and a gas flows through the filter media packs from a dirty gas side of the filter to a clean gas side of the filter in order to clean the gas. A respective protective grid of the protective grids is arranged on each filter media pack on the clean gas side. The protective grids have a grid structure with substantially closed curves of different sizes arranged centrically around at least one centre of the protective grid and with a plurality of connectors, which are oriented radially with respect to the centre of the protective grid and connect the closed curves to one another.

Abstract: A computer-implemented method for building trusted executable software using trusted building units, wherein a path between the building units is untrusted, is disclosed. The method comprises generating, by each of the trusted building units, an identifier for identifying an output of the respective trusted building unit, wherein the respective trusted building unit also generates a signed confirmative certificate comprising the identifier. The method comprise as well utilizing, by each of the distributed trusted building units, output results of at least one of a predecessor build unit of the trusted building unit as input, validating that each of the signed confirmative certificates conforms to a predefined set of policy rules, and upon a failed validating of the signed confirmative certificate of one of the trusted building units, terminating the building of the trusted executable software.

Abstract: A method provides anti-trap protection for a motor vehicle, in which a miniature safety edge is arranged on a first interior component which is movable in automated fashion relative to a second interior component by way of a control device. An automated movement of the interior components relative to one another via the control device is prevented when the miniature safety edge is actuated.

The method comprises generating, by each of the trusted building units, an identifier for identifying an output of the respective trusted building unit, wherein the respective trusted building unit also generates a signed confirmative certificate comprising the identifier. The method comprise as well utilizing, by each of the distributed trusted building units, output results of at least one of a predecessor build unit of the trusted building unit as input, validating that each of the signed confirmative certificates conforms to a predefined set of policy rules, and upon a failed validating of the signed confirmative certificate of one of the trusted building units, terminating the building of the trusted executable software.

Abstract: A vibration absorber which, in addition to a main mass which is fixed thereto and moved along a curved trajectory by a driving mechanism, comprises a substantially smaller variably adjustable rotating flywheel mass which is moved together with the main mass along the trajectory thereof, enabling the adjustment of the frequency of the absorber. The rotating flywheel mass is driven by a novel belt device independently of the driving mechanism. A rotating vibration absorber which, along with the main mass and the rotating flywheel mass, comprises its own damping unit, such as an eddy-current damping unit.

Abstract: The invention relates to a roller tappet (1) for a piston pump, in particular for a high-pressure fuel pump, for supporting a pump piston (2) which can move in a reciprocating motion on a cam (3) or eccentric of a drive shaft (4), comprising a tappet body (5) with an end-side recess (6) and two radial bores (7) which lie diametrically opposite one another at the recess (6) and receive a pin (8), on which a roller (10) is rotatably mounted directly or indirectly via a bearing bush (9), wherein at least one radially or obliquely running feed bore (12) is configured in the tappet body (5) in order to supply a lubricating medium to a radial bearing gap (11) which is configured between the roller (10) and the pin (8) or between the roller (10) and the bearing bush (9), which feed bore (12) opens into the recess (6) in the region of an axial bearing gap (13) between the roller (10) and the tappet body (5).
