A method of manufacturing a patient interface for sealed delivery of a flow of air at a continuously positive pressure with respect to ambient air pressure to an entrance to the patient's airways includes collecting anthropometric data of a patient's face. Anticipated considerations are identified from the collected anthropometric data during use of the patient interface. The collected anthropometric data is processed to provide a transformed data set based on the anticipated considerations, the transformed data set corresponding to at least one customised patient interface component. At least one patient interface component is modelled based on the transformed data set.

The present invention solves the problem of implementation of the divider for determining the golden section of eyebrow in relation to face, which would have an improved construction compared to the dividers known in the art and would be easier to handle, and owing to the smaller number of visible structural elements would also have an innovative, improved design. Divider for determining the golden section of eyebrows according to the invention comprises two arms (1), which are pivotally connected to each other via a serrated gear, with each arm (1) having the longer part (b) and the shorter part (a) whose length ratios are equal to the golden ratio, i.e. 1.618, while the ratio of the distance (c) between the longer parts (b) of the arms and the distance (d) between the shorter parts (a) of the arms are also equal to the golden ratio, i.e. 1.618.

A scanner includes a camera, a light source for generating a probe light incorporating a spatial pattern, an optical system for transmitting the probe light towards the object and for transmitting at least a part of the light returned from the object to the camera, a focus element within the optical system for varying a position of a focus plane of the spatial pattern on the object, unit for obtaining at least one image from said array of sensor elements, unit for evaluating a correlation measure at each focus plane position between at least one image pixel and a weight function, a processor for determining the in-focus position(s) of each of a plurality of image pixels for a range of focus plane positions, or each of a plurality of groups of image pixels for a range of focus plane positions, and transforming in-focus data into 3D real world coordinates.

An orthopedic device comprises a body having a monolithic structure and arranged to form a closed circumference in a secured configuration, the body having a predetermined shape in an unsecured configuration. The body is formed continuously without interruption from at least one polymeric material. A method for making the orthopedic device includes providing a schematic including a model representing a body part for which the orthopedic device is intended, providing at least one array of coordinates and indicia corresponding to the coordinates proximate to the model at a plurality of locations along the model, and providing a scale set corresponding to the coordinates. The dimensions obtained from measuring the body part may be used to form a custom-shaped orthopedic device.
