Configurable neural network engine for convolutional filter sizes
Some embodiments include a special-purpose hardware accelerator that can perform specialized machine learning tasks during both training and inference stages. For example, this hardware accelerator uses a systolic array having a number of data processing units (“DPUs”) that are each connected to a small number of other DPUs in a local region. Data from the many nodes of a neural network is pulsed through these DPUs with associated tags that identify where such data was originated or processed, such that each DPU has knowledge of where incoming data originated and thus is able to compute the data as specified by the architecture of the neural network. These tags enable the systolic neural network engine to perform computations during backpropagation, such that the systolic neural network engine is able to support training. |

Data filtering utilizing constructed graph structure
A global filter allows data filtering using attributes across multiple Analysis Tools (ATs), by broadcasting semantic filter context objects. Upon selecting object attribute values, the filter context object is created with attribute names and values.

A lateral filter finds related entities in a relational database, without having to maintain and/or duplicate all of the data into a graph database. The processing engine resolves lateral filters using an entity graph path calculation conducted in conjunction with the generation of a bootstrapped graph structure. That graph structure is constructed (bootstrapped) utilizing available database schematic information—e.g., pre-calculated (key) relations and metadata read from the relational database. From that information, relationships in the bootstrapped graph structure are determined. Possible paths between entities are used to generate an optimized SQL query to reach target data. |

Software transport check integration in upgrade context
Embodiments offer early assessment of upgrade compliance checking upon software landscape production data, prior to actually executing a full impact analysis. In a pre-transport phase, discrete upgrade compliance checks are run and corresponding reports returned to individual developers. In a transport phase, batches of combined compliance checks (bundled into released transports) are run and corresponding reports returned to higher level users. According to certain embodiments, pre-transport and/or transport compliance checking is performed upon landscape production data condensed to a bi-value states. Such condensing can desirably reduce stored data volumes and impart security. According to some embodiments, pre-transport and/or transport compliance checking is performed upon production data merged across multiple landscapes. This avoids storing redundant upgrade check data. Early indication of compliance checking violations, can reduce the incidence of last-minute compliance problems arising during subsequent full impact analysis (which is fraught with potential consequences for system down-time). |

The blocking cam is arranged for positive engagement with a tooth gap of a parking lock gear and the actuating device is for transferring an actuating force to the blocking cam. The energy store is for transferring the actuating force from the actuating device to the blocking cam, the blocking drive is for displacing the actuating device, and the intermediate element is freely displaceable relative to the blocking drive over a predetermined intermediate path for displacing the actuating device. The blocking cam is arranged to positively engage the tooth gap to block rotational movement of the parking lock gear when the actuating device is in a blocked position, and the parking lock gear is rotatable when the actuating device is in an open position. |

Assembly of an axle or a shaft on a component, in particular for a vehicle, and vehicle comprising such an assembly
An assembly of a first component designed as an axle or a shaft on a second component, is provided, in particular for a vehicle. The first component is secured to the second component at least in the axial direction of the first component. At least one of the components has at least one first deformation on one side, the deformation being used to secure the first component on the second component in a first direction which coincides with the axial direction. At least one of the components has at least one second deformation on the same side, the second deformation being used to secure the first component on the second component in a second direction which coincides with the axial direction and is opposite the first direction. |

Complex planetary gear unit
A planetary gear unit includes a first gear, a second gear, and a third gear arranged coaxially while allowed to rotate relatively. A first planetary gear and a second planetary gear are integral, and a third planetary gear and a fourth planetary gear are integral. The planetary gears are rotatably supported by a carrier. The first planetary gear is meshed with the first gear, the second planetary gear is meshed with the second gear, the third planetary gear is meshed with the second gear, and the fourth planetary gear is meshed with the third gear. A gear ratio between the first planetary gear and the first gear is different from a gear ratio between the second planetary gear and the second gear, and a gear ratio between the third planetary gear and the second gear is different from a gear ratio between the fourth planetary gear and the third gear. |

Gear reducer and gearmotor
A gear reducer has a helical gear, an eccentric shaft that is joined to the helical gear and has a first supporting portion that is offset in a rotation radial direction with respect to a rotation shaft of the helical gear, and a slider plate that is disposed at a radial direction outer side of the eccentric shaft. Further, the gear reducer has a transmitting gear that is supported at a first supporting portion, and whose rotation around its own axis is restricted due to the transmitting gear being engaged with the slider plate, and that revolves due to the helical gear rotating together with the eccentric shaft, and has an output gear body that rotates due to the transmitting gear revolving. The transmitting gear has a pair of restricting projections that project-out toward the slider plate side, and the slider plate is disposed between the pair of restricting projections. |

Spacer and cycloidal reducer with the spacer
A spacer includes a first surface and a second surface. The first surface and the second surface respectively have two opposite first roller accommodating grooves and two opposite second roller accommodating grooves. The first and second roller accommodating grooves of the first surface correspond to the second and first roller accommodating grooves of the second surface. The spacer defines a reference plane, which is perpendicular to a horizontal direction and passes through a center point of the maximum thickness of the spacer. The horizontal distance from the reference plane to the center of each first roller accommodating groove is different from the horizontal distance from the reference plane to the center of each second roller accommodating groove. By flipping the spacer of the present invention, the spacing of two adjacent rollers can be adjusted. In addition, the present invention further provides a cycloidal reducer with the aforementioned spacer. |
