Manikins with human-like chest properties--a new tool for chest compression research.

Commercially available training manikins for cardiopulmonary resuscitation (CPR) do not accurately mimic the mechanical properties of human chests. This may limit the usefulness of CPR research performed on such manikins. This paper presents the construction of manikins with chest properties matching those measured in patients during an ongoing CPR.

Utilizing characteristic electrical properties of the epidermal skin layers to detect fake fingers in biometric fingerprint systems--a pilot study.

Electronic fingerprint systems are now gaining acceptance in mainstream consumer applications worldwide. It has been shown, however, that about 80% of these systems are easily fooled with different kinds of fake fingers with imprinted patterns. Hence, a live finger detection mechanism will be a crucial part of any fingerprint system used in security applications.

Anterior-posterior thoracic force-deflection characteristics measured during cardiopulmonary resuscitation: comparison to post-mortem human subject data.

Comparative data of thoracic compression response between live vs. post mortem human subjects (PMHS) has been reported, but the live subject tests are often at low deflections and include the effects of muscle tensing. Novel technology has been developed that overcomes several of these limitations.
