A system assesses activity and displays a unitless activity value. A detector senses activity of a user. A processor reads sensed activity data from the detector. A display displays the unitless activity value. An enclosure houses the detector and the processor. The processor periodically reads the sensed activity data from the detector and processes the data to generate an activity number, the number being used to generate the unitless activity value based upon a maximum number and a display range.

A test device for determining the prickle property of the fabrics objectively includes nails on a measuring head fixed in an upper region of the test device, wherein the nails come in the contact with stiff fibers. The test device also includes an operation panel, a light source, a camera, a sample holder. The measurement uses a circular movement of the fabric instead of a linear movement unlike the previous studies. The measuring head does not apply any pressure on the fabric, only by lowering the measurement head, the nails squeezed in the head penetrate in the hairs of the fabric. In this situation, during the movement of the head, prickle force caused by the fiber ends can be detected. With the test device, it is possible to test both woven and knitted fabrics.

A helmet testing apparatus includes a sensor configured to be selectively positionable within an interior head cavity of a helmet to acquire compliance data regarding a liner of the helmet and a processing circuit configured to determine a rating for the helmet based on the compliance data and predetermined compliance parameters for the helmet.

A helmet testing apparatus including a movable member, a sensor coupled to the movable member and configured to acquire compliance data regarding a liner disposed within a shell of a helmet through engagement of the sensor with the liner, and a processing circuit configured to determine a rating for the helmet based on the compliance data and predetermined compliance parameters for the helmet.
