Abstract: A hollow tubular foam spring having a plurality of radially extending holes extending from an outer surface towards a central hollow core. The tubular foam spring is arranged with wall thickness and diameter to height ratios such that center bulging is achieved under compressive loads. In an embodiment, such as in a mattress, seat, cushion or pillow, springs are arranged in an array whereby some impinge upon one another due to central bulging.

Abstract: The invention relates to a method for determining the position of at least one object (13, 22, 23), which is characterized in that images of at least one object (13, 22, 23) are captured by means of a single electronic camera (21). At least one optical auxiliary structure (1) is arranged on the object (13, 22, 23) to be measured or on other constructions that have a permanent spatial relationship to the object (13, 22, 23) to be measured. The measures/positions of the at least one object (13, 22, 23) in relation to the at least one reference position or a reference position which is simultaneously captured by the camera (21) are determined by evaluating the positions of the at least one auxiliary structure (1) in the captured images by means of a computer program.
