Abstract: Disclosed are methodologies, a system and components thereof and associated computer programs for providing training/testing of one or more users performing treatment of Sudden Cardiac Arrest (SCA) victims. The system provides computer controlled interactive instruction and testing methodologies that enable one or more users to be trained and/or tested using a plurality of mannequins including circuitry and hardware that enable each users compressions to analyzed for rate, depth and recoil to ensure that each user is performing the chest compressions properly. The data collected for determining rate, depth and recoil are collected via mannequin-specific hardware and electronics that utilize a plurality of magnets provided in proximity to a Hall Effect sensor. Data is collected at each mannequin and transmitted to at least one computer processing unit operating to receive, collect, analyze and display the data as well as store data for subsequent use in individualized training and certification of users.

Abstract: The present disclosure generally relates to systems and devices for spraying fluid materials such as paints, stains, and the like, and more specifically, but not by limitation, to a fluid level indicator for an airless fluid sprayer. In one example, an airless fluid sprayer is provided and includes a fluid container, a controller, and a fluid level indication module implemented by the controller to generate an indication of a level of fluid material in the fluid container.

Abstract: A fluid delivery system includes a pump operably coupleable to a source of fluid. A reciprocating electromagnetic actuator is coupled to the pump and has a coil that when energized causes the actuator to drive the pump. Coil current sensing circuitry is configured to provide an indication of current flowing in the coil. A controller is coupled to the coil current sensing circuitry and is configured to calculate a coil drive parameter based upon a plurality of coil current indications from the coil current sensing circuitry. Coil drive circuitry is coupled to the controller and is configured to supply current to the coil based on the coil drive parameter.
