The invention relates to a double-layer component (1) having a first layer (2) and a second layer (3), wherein the layers (2, 3) are connected to one another, wherein the two layers (2, 3) have different coefficients of thermal expansion, wherein the first layer (2) comprises a first plastic and the second layer (3) comprises a second plastic or carbon fibres, wherein the double-layer component (1) is reversibly deformable under the influence of heat. The double-layer component (1) is improved in that the double-layer component (1) can be inserted into a heat engine (4), wherein the thickness of the double-layer component (1) is at least 0.1 mm, wherein the thickness of the double-layer component (1) is 5 cm or less than 5 cm.
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.
摘要:
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.

According to the invention, balancing weights (18) can be fastened to the radial ends of the fan blades (12).
摘要:
A method and system for the diagnosis of 3D images are disclosed, which significantly cuts the time required for the diagnosis. The 3D images are for example an image volume dataset of a magnetic resonance tomography system which is saved in an RIS or PACS system. In at least one embodiment, the diagnostic finding are partially automatically generated, and details of the position, size and change in pathological structures are compared to previous diagnostic findings are generated automatically. As a result of this automation the diagnostic work of radiologists is significantly reduced.
