A method for fabricating a custom anatomical cushion and a device to capture pressure controlled shape is provided. The device comprises, generally, a flexible membrane enclosing floating beads adapted to be completely immersed and freely moving inside a fluid. The device further comprises a mesh adapted to stop the floating beads from going outside of the flexible membrane as a result of a pressure increase or decrease inside the flexible membrane. The device is being fluidly connected to a pressure control system adapted to increase and/or decrease the internal pressure of the flexible membrane and comprises a vibration/leveling system adapted to adjust the fluid level inside the flexible membrane.

Method for fabricating anatomical cushion and device to capture pressure controlled shape

The invention discloses a body cushioning pad, a body contact mat and a multi-layered cushioning structure composed of the body cushioning pad and the body contact mat. The cushioning pad consists of a plurality of foam blocks, each provided with an internal cavity having a predetermined size and shape to control the firmness of the block and means for maintaining the foam blocks as a unit. The body contact mat is a bi-dimensional latticed structure of spaced-apart studs made of a compressible material linked together by flexible linking elements. The multi-layered cushioning structure comprises both the cushioning pad and the body contact mat, and a wrapper to wrap the cushioning pad and the contact mat together.

A camera calibrating apparatus uses a calibration target in combination with a laser source generating a laser beam defining a calibration plane and intersecting the camera field of view to define an object imaging area. The calibration target includes a frame defining a coplanar arrangement of more than five reference points having known position coordinates within an object reference system. The frame is disposed in a camera calibration position wherein the coplanar arrangement of reference points is substantially parallel to the calibration plane. The target includes an arrangement of light reflecting members protruding from the arrangement of reference points in a direction substantially perpendicular thereto so as to extend within the object imaging area, to allow the camera to capture an image formed by illuminated portions of the light reflecting members. The apparatus further includes image processor means programmed on the basis a calibrated camera model to associate any position coordinates in the object reference system with corresponding position coordinates in an image reference system.

Camera calibrating apparatus and method

A method and system for monitoring the quality of log cutting either off-line or in real-time is based on optical measurement of half-squared or full-squared cants characteristics as produced at primary or secondary cutting stage, so as to increase the proportion of high-value wood pieces that can be recovered from full squared-cants produced at the sawing stage. The log is fed lengthwise to a primary cutting station (canter) capable of producing the first pair of opposing cut faces, while guiding the log substantially in a direction of the machine axis. The profile of the peripheral log surface at a plurality of cross-sections along the machine axis is measured to generate corresponding post-cut profile data, from which an estimation of log raw profile characteristics is made, to generate corresponding raw profile data. Then, from post-cut and raw profile data, resulting data on at least one parameter related to the cutting quality of the log. The proposed monitoring system and method provide accurate control of target dimensions, while optimizing the adjustment of other quality related parameters such as faces parallelism and cant centering, as well as to measure the level of some surface defects generated at cutting such as knife marks, stripping and roughness, in order to obtain a more complete performance diagnostic.
