摘要:
A method and apparatus for hierarchical parsing and semantic navigation of a full or partial body computed tomography CT scan is disclosed. In particular, organs are segmented and anatomic landmarks are detected in a full or partial body CT volume. One or more predetermined slices of the CT volume are detected. A plurality of anatomic landmarks and organ centers are then detected in the CT volume using a discriminative anatomical network, each detected in a portion of the CT volume constrained by at least one of the detected slices. A plurality of organs, such as heart, liver, kidneys, spleen, bladder, and prostate, are detected in a sense of a bounding box and segmented in the CT volume, detection of each organ bounding box constrained by the detected organ centers and anatomic landmarks. Organ segmentation is via a database-guided segmentation method.

A vehicle electrical system component for a data transmission system in a motor vehicle, in particular for an Ethernet transmission system, having a cable with wires and a plug having wire connection contacts for contacting the wires, wherein the wires have an electrical insulation, wherein a common shielding is arranged around the wires which is enclosed by a common cable sheath, wherein the cable has at least three wires and an electrically conductive drain wire, wherein the drain wire contacts the shielding at least in sections and is contacted to a wire connection contact of the plug.
摘要:
An adapter element for serial data transfer in a vehicle, the adapter element including a first housing part, which is designed electrically conductively and is connectable to a shield and a second housing part, which is designed electrically conductively and includes a contact element. The first housing part and the second housing part are disposed such that the second housing part is enclosed by the first housing part in a first region that extends along a longitudinal axis of the adapter element. The contact element is in electrical contact in the first region with the first housing part, and the contact element produces the electrical contact at least in part by the adapter element being configured such that accessibility to the contact element from a position exterior to the adapter element in a direction that is orthogonal to the longitudinal axis is ensured. In addition, the second housing part is surrounded on both sides of the first housing part by the first housing part inside a second region, which extends along the longitudinal axis.

The present invention relates to a process for manufacturing N-Formyl-1-amino-3,5-dimethyladamantane, an intermediate product in the overall process of producing 1-Amino-3,5-dimethyladamantane hydrochloride (Memantine). Therein, the process comprises the following steps: (a) reacting 1,3-dimethyladamantane with an acid mixture comprising concentrated sulfuric acid and concentrated nitric acid, wherein 1 to 6 volume parts of sulfuric acid (measured in ml) are used per weight part of 1,3-dimethyladamantane (measured in g); (b) reacting the solution from step (a) with an amount of formamide varying from 1 to 5 molar equivalents per mole of deprotonated 1,3-dimethyladamantane from step (a) to obtain N-Formyl-1-amino-3,5-dimethyladamantane. In step (b), the molar ratio of total acid, i.e. the molar amount of sulfuric acid and the molar amount of nitric acid taken together versus the molar amount of formamide is at least 1.5 and that the temperature is at least 50° C. The present invention also relates to the overall process of manufacturing Memantine from 1,3-dimethyladamantane by means of hydrolyzing the intermediate NFORM.
