Abstract: A safety system is disclosed to provide safety to a user while traversing an amusement attraction. The safety system may include one or more safety mechanisms for attachment to a user and a track system. The one or more safety mechanisms may removably couple together. The one or more safety mechanisms may include additional features such as speed controllers, track engagement systems, among others to assist in the traversal of the safety mechanism through and across the track system.

Abstract: A bifurcation method and system for a passive continuous belay system that allows for a user to select multiple pathways using intermediate tracks. A main track and the intermediate tracks provide a linear passive continuous belay using an anchor mechanism that is configured to grasp the outside of the structural member track, using rolling elements and/or low-friction sliding. The user may select multiple pathways using intermediate lateral tracks to provide Cartesian movement at designated (e.g., perpendicular) transition or junction points. Desired tracks may be selected by a user via sliding along a support plate or track in a junction box and/or by rotating a portion of the junction box. Amusement attraction activities that include non-harnessed play may be intertwined or located adjacent to activities utilizing harnessed play.

Abstract: The present invention provides methods for predicting a patient's risk of an adverse drug reaction to a thiopurine drug such as AZA or 6-MP by genotyping the patient for a polymorphism in the gene encoding ITPase (ITPA). The present invention also provides methods for predicting a patient's risk of an adverse drug reaction to a thiopurine drug by determining a level of ITPase activity or ITP in a sample from the patient. The present invention further provides methods for optimizing therapeutic efficacy in a patient receiving a thiopurine drug by determining whether the patient should be given an alternative drug based on the presence or absence of a polymorphism in the ITPA gene.
