Processes for optimizing the geometry of a blade for use in a propeller are disclosed. In one exemplary process, an optimization routine that generates new blade geometries based on structural parameters and calculates performance parameters of each blade geometry, including aerodynamic performance parameters, farfield acoustic parameters, and/or electrical power requirements to operate a propeller having the blade geometry, is performed. The optimization routine receives design parameters and weightings from a user and can use one or more surrogate algorithms to map a design space of the weighted values of the design parameters to find their local minima. The optimization routine then determines an optimized blade geometry using a gradient-based algorithm to generate new blade geometries to explore the minima until the weighted values of the design parameters converge at an optimized blade geometry representing the global minima of the design space.

A method of planning a platform lift. The platform lift includes a rail, platform, chair, and a drive unit attached to the platform to drive the platform along the rail. The method includes acquiring 3D-data of a stair on which the platform lift is to be installed utilizing an augmented reality device. Calculating a travel path of the rail is based on acquired 3D-data and predetermined clearance information. Visualizing part or all of the platform lift is based on the calculated path of travel via the augmented reality device. Acquiring the 3D-data includes observing the stair with the augmented reality device; marking several locations and confirming the locations via a user input; extracting surface information via a computer based analysis of the markings and optical information taken by the augmented reality device. Based on the optical information and predetermined clearance information the path of travel is calculated.

A method for designing a planetary gearset meeting one or more design targets is described. Initially, a size and ratio of the planetary gear set, and the number of planet gears for the planetary gearset is specified. All valid combinations of tooth numbers and planet numbers that satisfy one or more constraints are then calculated. From these, a starting combination is selected and a value for a design target for the gear set is calculated. One or more of the macro-geometry parameters are modified, and the macrogeometry parameters are chosen such that the positive effects of one macrogeometry parameter on the design target counteract any negative effects of another macrogeometry parameter. In this way, a design for planetary gearset meeting the one or more design targets is produced. Also disclosed is a method additionally calculating a sideband distribution resulting from the selected combination. The side band distribution is compared with a design target for sideband distribution and parameters are varied as necessary to achieve the required design.

A system allows a user to create new designs for apparel and preview these designs before manufacture. Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. The system swaps garments in a digital asset to garments that are designed using the system. The wear pattern is created by a laser using a laser input file. Generating the preview image comprises combining first and second contributions to obtain a combined value for a pixel at the pixel location of the preview image.
