Safety performance testing of climbing helmet-mounted cameras.

Background: No research establishing the effects of climbing helmet-mounted cameras on head injury biomechanics.

Objective: Establish the potential effects of climbing helmet-mounted cameras on the injury risks associated with falling object strikes and falls onto flat and angled surfaces.

Methods: Three experimental studies were developed via the adaptation of European helmet testing standards and regulations.

Evaluation of near-side oblique frontal impacts using THOR with SD3 shoulder.

Objective: Within the EC Seventh Framework project THORAX, the Mod-Kit THOR was upgraded with a new thorax and shoulder. The aim of this study was to investigate whether the THOR ATD met a set of prerequisites to a greater extent than Hybrid III and by that measure whether the dummy could serve as a potential tool for future evaluation of serious head and chest injuries in near-side oblique frontal impacts.

Method: A small-overlap/oblique sled system was used to reflect occupant forces observed in oblique frontal crashes.

The repeatability and reproducibility of the BioRID IIg in a repeatable laboratory seat based on a production car seat.

Objective: The United Nations Economic Commission for Europe Informal Group on GTR No. 7 Phase 2 are working to define a build level for the BioRID II rear impact (whiplash) crash test dummy that ensures repeatable and reproducible performance in a test procedure that has been proposed for future legislation. This includes the specification of dummy hardware, as well as the development of comprehensive certification procedures for the dummy.

Injury risk curves for the WorldSID 50th male dummy.

The development of the WorldSID 50th percentile male dummy was initiated in 1997 by the International Organisation for Standardisation (ISO/TC22/SC12/WG5) with the objective of developing a more biofidelic side impact dummy and supporting the adoption of a harmonised dummy into regulations. The dummy is currently under evaluation at the Working Party on Passive Safety (GRSP) in order to be included in the pole side impact global technical regulation (GTR). Injury risk curves dedicated to this dummy and built on behalf of ISO/TC22/SC12/WG6 were proposed in order to assess the occupant safety performance (Petitjean et al.

The effect of strain rate on the mechanical properties of human cortical bone.

Bone mechanical properties are typically evaluated at relatively low strain rates. However, the strain rate related to traumatic failure is likely to be orders of magnitude higher and this higher strain rate is likely to affect the mechanical properties. Previous work reporting on the effect of strain rate on the mechanical properties of bone predominantly used nonhuman bone.
