Abstract: In some embodiments of the present disclosure, augmented reality and/or virtual reality technologies are used to present information for a vehicle to a technician. A virtual object model file that includes a context model and at least one assembly detail model is created based on a vehicle design model. A VR/AR device uses its camera to generate video of a vehicle, and superimposes a depiction of a vehicle component or assembly from the virtual object model file over the video in the location in which the vehicle component or assembly is actually located, as if the vehicle were “see-through.” The VR/AR device may then also allow the technician to select specific components of the depicted assembly in order to retrieve and display detailed information about the component.

Abstract: A method of designing a freeform surface optical system with dispersion elements is provided. A nondispersive spherical optical system comprising a nondispersive sphere is constructed. A dispersion element is placed on the nondispersive sphere to construct a dispersive spherical optical system comprising a dispersive sphere. The dispersive spherical optical system is constructed into a dispersive freeform surface optical system comprising a freeform surface. The coordinates of the feature data points on the freeform surface are kept unchanged, and the normal vectors are recalculated. The coordinates and new normal vectors are fitted to obtain a new freeform surface. An iterative algorithm is performed until all freeform surfaces are recalculated to new freeform surfaces.

Abstract: Method and system for brace designing. The method comprises the following steps: S1) fixing a subject requiring a brace; S2) acquiring skeletal image information of the subject; S3) determining an adjustment solution for implementing an adjustment with respect to the subject and a target state that is to be achieved ultimately; S4) adjusting the subject to alter the skeletal structure of the subject; S5) acquiring adjusted skeletal image information of the subject; S6) determining whether the skeleton of the subject has been adjusted to the target state; if yes, then terminating adjustment and entering step S7; if not, then returning to step S4; S7) acquiring the body surface three-dimensional shape of the subject having achieved the target state and recording information of the force applied by an adjusting head to the subject for use in manufacturing a corresponding brace; thus allowing the highly efficient designing of a brace.

Abstract: In a method of deriving the buckling condition of a cylindrical fiber moving in a fluid, a method of calculating the breakage condition thereof, and a method of forecasting the fiber length distribution, the flow field around a cylindrical fiber in a contraction flow is determined by a stricter method.The method of deriving the buckling condition, which is a condition under which buckling occurs, of a cylindrical fiber moving in a fluid, includes the step of multiplying a dimensionless fluid stress distribution, uniquely determined with regard to the aspect ratio r0′ of the cylindrical fiber, by μk (where μ represents fluid viscosity and k represents the contraction rate (velocity gradient in the length direction at the location where the fiber is present)) at a location where the cylinder is present, to obtain the fluid stress distribution acting on the cylinder surface in a contraction flow, and the step of using a minimum eigenvalue λ0, which is the threshold for buckling derived from the fluid stress distribution on the cylinder surface, to derive the buckling condition, wherein the buckling condition is represented by μk≥−(λ0Er0′4 log r0″)/4 (where E is Young's modulus and r0′ is the aspect ratio of the cylinder).

Abstract: A fracture determination device is provided which can predict fracture in an ultra-hard steel material. This fracture determination device 1 is provided with: a reference forming limit value generation unit 22 which, on the basis of reference forming limit value information, generates a reference forming limit value for a reference element size, which is the element size used as a reference; a target forming limit value generation unit 23 which uses the tensile strength of the steel material to change the reference forming limit value, predict the forming limit value for the element size and generate a target forming limit value; an analysis running unit 24 which runs a deformation analysis using input information and which outputs deformation information including the strain of each of the elements; a principal strain determination unit 25 which determines the maximum principal strain and the minimum principal strain of each of the elements included in the deformation information; and a fracture determination unit 26 which, on the basis of the determined maximum principal strain and minimum principal strain of each of the elements and the target forming limit value, determines whether each element in the analysis model will fracture.

Abstract: Techniques which may allow computer-aided design (CAD) conversion are described. In one implementation, CAD conversion may convert all objects placed in a 3D CAD model via a customized symbol into an object independent of that symbol, or in the case of parametric symbols, the user-defined form utilized for its placement. CAD conversion may also remove all constructions associated with the utilization of that symbol from any databases or files associated with the 3D CAD model.

Abstract: A method of detecting whether a receiver coil is near a transmit coil in a wireless power transfer system (WPTS), the method involving: applying a pseudo-random signal to the transmit coil; while the pseudo-random signal is being applied to the transmit coil, recording one or more signals produced within the WPTS in response to the applied pseudo-random signal; by using the one or more recorded signals, generating a dynamic system model for some aspect of the WPTS; and using the generated dynamic system model in combination with stored training data to determine whether an object having characteristics distinguishing the object as a receiver coil is near the transmit coil.

Abstract: A computer-implemented method designs a tying bar enclosing a plurality of concrete-reinforcing bars in a 3D scene of a computer-aided design system. The method a) provides the three-dimensional models of the concrete-reinforcing bars to be enclosed by the tying bar; and b) computes a set of traces of each of the concrete-reinforcing bars. Each trace has a trace center. Next a set of connection lines is computed. Each connection line binds the trace centers. A set of circular arcs is computed. Each circular arc surrounds at least partially a respective trace, and a set of segments. Each segment is approximately parallel to a respective connection line and connects consecutive circular arcs. The segments and circular arcs form a center curve of the tying bar in the sketch plane. Lastly, the tying bar is designed based on the center curve and the bar radius of the tying bar.

Abstract: A computer-implemented method manipulates a 3D object in a 3D scene of a computer-aided design system, by: (i) displaying a 3D object having a center of rotation in the 3D scene on a screen; (ii) displaying in the 3D scene a rotation manipulator (RM) having three areas (RA1, RA2, RA3) perpendicular to each other, and each area (RA1, RA2, RA3) corresponding to a rotation plane, and (iii) activating the rotation manipulator. The rotation manipulator (RM) follows the cursor (C) on the screen. The rotation manipulator is activated by locking its location on the screen on an initial press point (PP). One rotation plane is selected by displacing the cursor (C) to the area (RA1, RA2, RA3) corresponding to said plane. A rotation manipulation is performed according to the displacement of the cursor (C) on the screen.
