    摘要: Visual-inertial tracking of an eyewear device using a rolling shutter camera(s). The eyewear device includes a position determining system. Visual-inertial tracking is implemented by sensing motion of the eyewear device. An initial pose is obtained for a rolling shutter camera and an image of an environment is captured. The image includes feature points captured at a particular capture time. A number of poses for the rolling shutter camera is computed based on the initial pose and sensed movement of the device. The number of computed poses is responsive to the sensed movement of the mobile device. A computed pose is selected for each feature point in the image by matching the particular capture time for the feature point to the particular computed time for the computed pose. The position of the mobile device is determined within the environment using the feature points and the selected computed poses for the feature points.

    摘要: A reading device, system, storage medium and method for capturing computer-readable codes of a medical product or packaging. The method includes: capturing an image of the product or packaging, extracting first and second computer-readable code, interpreting code data, retrieving a product-ID and further product information from the code data, determining if relevant information is included in the information of the captured code and/or a linked database, selecting the second code as a relevant code if retrieved information of the first code is fully included in the retrieved information of the second code, or selecting the first and second codes as the relevant code if each code includes relevant information, transmitting a code marker for each code to a displaying device, and displaying an overlay image with the captured image and a marking of the code to provide an improved overview of the computer-readable codes to the user.

    摘要: A transport container for receiving and transporting goods within a transport or distribution system by conveyor belts and/or roller conveyors. The transport container includes a base from which four sidewalls extend. At least two opposing sidewalls each have a predefined code section to apply a machine-readable code, in particular a barcode or a QR code, and at least one opening, in particular a plurality of slots extending from the base to the upper edge of the sidewall. The openings in the two opposing sidewalls, in particular those openings which are located directly adjacent to and/or at the same height as the predefined code sections, are arranged offset from one another. A system can include the transport container, a conveyor system, and a scanning device.

    摘要: An endoscope with a folding mechanism for foldably or bendably holding an endoscopy head at the distal end of the endoscope, preferably an endoscope shaft, having a number of axially successive segments that are adjustable via an actuating element. The segments define at least one channel for the passage of minimally invasive surgical instruments, flushing media, supply lines and the like. The segments are in the form of wedge-shaped cylinder sections having end faces oriented relative to each other in a wedge-shaped manner. Each cylinder section receives a cylinder jacket portion having a minimum axial length and an opposite cylinder jacket portion having a maximum axial length. Two directly adjacent segments are mutually oriented such that they are axially supported on or axially abut the relevant cylinder jacket portions of maximum axial length, which results in hinge- or joint-contact occurring on the support or placement point.
