Assembly Instructions

Montageanleitungen sind unabdingbar, um ein Produkt erfolgreich zu verkaufen. Zugleich sind sie sehr zeitaufwendig in der Erstellung und oft nicht gut verständlich. „ARCaide“ ist eine neue Methode, die vorhandene CAD-Daten nutzt und daraus automatisch eine Montageanleitung erstellt. Ein weiterer Vorteil: Die ausgegebene Anleitung ist intuitiv und reduziert Montagefehler schon während des Prozesses, weil sie den Menschen mithilfe von Augmented Reality (AR) anleitet.   Assembly instructions are indispensable for successfully selling a product. However, their creation is very time-consuming and often they are hard to understand. ARCaide is a new method using existing CAD data to automatically create assembly instructions. Another advantage is that these instructions are intuitive, reducing assembly errors during the process as users are guided by means of Augmented Reality (AR).

Background: This report discusses the utility of a wearable augmented reality platform in neurosurgery for parasagittal and convexity en plaque meningiomas with bone flap removal and custom-made cranioplasty. Methods: A real patient with en plaque cranial vault meningioma with diffuse and extensive dural involvement, extracranial extension into the calvarium, and homogeneous contrast enhancement on gadolinium-enhanced T1-weighted MRI, was selected for this case study. A patient-specific manikin was designed starting with the segmentation of the patient’s preoperative MRI images to simulate a craniotomy procedure. Surgical planning was performed according to the segmented anatomy, and customized bone flaps were designed accordingly. During the surgical simulation stage, the VOSTARS head-mounted display was used to accurately display the planned craniotomy trajectory over the manikin skull. The precision of the craniotomy was assessed based on the evaluation of previously prepared custom-made bone flaps. Results: A bone flap with a radius 0.5 mm smaller than the radius of an ideal craniotomy fitted perfectly over the performed craniotomy, demonstrating an error of less than ±1 mm in the task execution. The results of this laboratory-based experiment suggest that the proposed augmented reality platform helps in simulating convexity en plaque meningioma resection and custom-made cranioplasty, as carefully planned in the preoperative phase. Conclusions: Augmented reality head-mounted displays have the potential to be a useful adjunct in tumor surgical resection, cranial vault lesion craniotomy and also skull base surgery, but more study with large series is needed.

Time And Energy

How to control the movement of the mechanical arm is a challenging topic recently. It requires much time and energy to program every joint. This paper proposes a new method based on 3D coordinates of the human arm joints, which helps the mechanical arm to imitate the movement of human arms and only needs to calculate angles of human arms’ joints according to the 3D coordinates. Here in this process the key is to get the information of 3D coordinates of human arms. This paper applies an AR (Augmented Reality) application of body detection with LiDAR on iPad Pro 2020 to get 3D coordinates. Then the calculated angle information is transferred from the host computer to the Arduino board controlling the movement of the mechanical arm. Eventually the same movements will be made by the mechanical arm and the human arm.

Investigations which require electron microscope examination of a few specific areas of non-homogeneous tissues make random sampling of small blocks an inefficient and unrewarding procedure. Therefore, several investigators have devised methods which allow obtaining sample blocks for electron microscopy from region of tissue previously identified by light microscopy of present here techniques which make possible: 1) sampling tissue for electron microscopy from selected areas previously identified by light microscopy of relatively large pieces of tissue; 2) dehydration and embedding large numbers of individually identified blocks while keeping each one separate; 3) a new method of maintaining specific orientation of blocks during embedding; 4) special light microscopic staining or fluorescent procedures and electron microscopy on immediately adjacent small areas of tissue.
