Estimating Lower Limb Kinematics Using a Reduced Wearable Sensor Count.

Goal: This paper presents an algorithm for accurately estimating pelvis, thigh, and shank kinematics during walking using only three wearable inertial sensors.

Methods: The algorithm makes novel use of a constrained Kalman filter (CKF). The algorithm iterates through the prediction (kinematic equation), measurement (pelvis position pseudo-measurements, zero velocity update, flat-floor assumption, and covariance limiter), and constraint update (formulation of hinged knee joints and ball-and-socket hip joints).

Economic impact of Wicks v State Rail Authority (NSW) (2010) 84 ALJR 497.

In Wicks v State Rail Authority (NSW) (2010) 84 ALJR 497 the High Court of Australia held that, among other things, plaintiffs (who establish that they suffer a recognised psychiatric illness as a result of the breach of duty of care owed to them by the defendant under s 32 of the Civil Liability Act 2002 (NSW)) are entitled to recover damages for pure mental harm under s 30 if their psychiatric injury arose "wholly or partly from" a "series of shocking experiences" in the form of "a sudden and disturbing impression on the mind and feelings" in connection with witnessing at the scene "another person ('the victim') being killed, injured or put in peril by the act or omission of the defendant". The High Court construed the phrase "being ..
