Abstract:
A system for simultaneously measuring the indentation hardness properties, span properties, and resilience properties of a mattress, comprising a first indentation means and a second indentation means, and means for urging the first indentation means and the second indentation means, into the mattress with a predetermined force, and also comprising laser means for projecting a while a projected laser line configured to map, preferably, by photographic triangulation, the amplitude, shape, and time-dependency of the resultant deflection of the mattress surface between the first indentation means and the second indentation means. The present invention also provides a method for simultaneously measuring the indentation hardness properties, span properties, and resilience properties of a mattress.
Abstract:
The invention provides a system for using optical mapping for producing a 3 dimensional mapping of the characteristics of a body; the system comprising measuring the movement of at least one registration mark on a capture sheet along a predetermined axis and means for using this measurement of the movement of the at least one registration mark to provide an indicator of the characteristics of the body. The invention also provides an apparatus for measuring body characteristics and a method of measuring body characteristics.
