Abstract: A simulation platform module. The simulation platform module determines that an external simulation object exists. The simulation platform module initiates the external simulation object into an executing state, and receives from the external simulation object an event mapping. The event mapping maps an input to an event implemented by the external simulation object in response to notification of the occurrence of the input, and an object attribute identifier that identifies an object attribute controlled by the external simulation object. The simulation platform module receives a user input from a user, and determines that the user input matches the input. The external simulation object is notified of the occurrence of the input, an input identifier that identifies the input is stored in a data structure.

Abstract: Described herein are methods for determining a target musculoskeletal activity cycle (MSKC) to cardiac cycle (CC) timing relationship. The method may include detecting a signal responsive to a cyclically-varying arterial blood flow at a location on a head of a user; providing a recurrent prompt at a frequency of the heart pump cycle using the signal, such that the signal correlates with a magnitude of blood flow adjacent to the location, and the recurrent prompt is provided to guide the user to time performance of a component of a rhythmic musculoskeletal activity with the recurrent prompt; and guiding the user to adjust a timing of the component of the rhythmic musculoskeletal activity to substantially maximize a magnitude of the signal. In some embodiments, the method further includes generating the recurrent prompt by amplifying the sound generated by the blood flow in or in proximity to an ear of the user.

Abstract: A method for providing an operator of a vehicle with operating information includes providing at least one predetermined demonstration of the operating information, deciding if one of the at least one predetermined demonstration is desired to be presented to the operator and, if desired, automatically presenting the demonstration to the operator in an operator compartment of the vehicle when the operator is in an operational position.

Abstract: A CPR patient training mannequin. The CPR patient training mannequin provides for training and teaching individuals in proper CPR technique. The mannequin includes a simulated torso section and simulated head section that enables a user to administer CPR and visually inspect the mannequin's response to the administration. The torso section utilizes a sensor configured to detect pressure exerted by a user performing chest compressions and includes one or more lights positioned in a simulated carotid artery and brain that are operably connected to the sensor. The lights are configured to illuminate to indicate the pressure exerted by a user. In an alternative embodiment, the torso section includes simulated lungs having lights that illuminate if a user properly performs a jaw-thrust maneuver and nose pinch on the mannequin.

Abstract: A method of supervising the safe carrying of firearms establishing rules for the situations where live ammunition is allowed to be in the chamber of the firearm. A supervisor checks that a dummy round is in the chamber of the firearm before the supervised person goes on duty outside of direct supervision. The dummy round is designed so that it records occasions when it is removed from the chamber. The recording is designed to last until checked by the supervisor. In some cases the dummy round undergoes changes that make the recording. In other cases the dummy round keeps count of the number of times it is removed from the chamber. In still other cases the dummy round communicates with a device which makes the recording. In each of these cases the system of supervision insures that live ammunition is only chambered when appropriate.
