Abstract: An input/output (“I/O”) system includes a plurality of input/output (“I/O”) ports, measurement circuitry, and an I/O multiplexer bus. The measurement circuitry is coupled to measure one or more electrical properties of one or more devices to be externally coupled to one or more of the I/O ports. The I/O multiplexer bus is coupled between the I/O ports and the measurement circuitry. The I/O multiplexer bus is programmable to selectively couple the measurement circuitry to any of the I/O ports.

Abstract: Apparatuses and methods for determining a deflection of a moveable conductive plate that is moved over a capacitive sensing device. The method may include moving the moveable conductive plate over sensor elements of the capacitive sensing device, and determining the deflection of the moveable conductive plate. In determining the deflection, a deflection magnitude and a deflection direction may be determined by calculating a vector of x- and y-directions or a vector of a radius and an angle.

Abstract: An electrotherapy delivery device includes an upper member having a handle portion and a pediatric electrode mounted to the bottom surface of the upper member. A base member having an adult electrode is selectively attached to the upper member with a coupling mechanism to conceal the pediatric electrode. The upper member attaches to the base member across diametrically opposed corners of the base member to provide the user with a more ergonomic hand position when accessing the paddles from the defibrillator. The device further include a plurality of switches operable to deliver a charge and to select the level of charge to be delivered to the patient. The paddle is provided with a processing circuit that receives an output from separate energy level increase and decrease switches, processes the output from the switches, and outputs a signal to the defibrillator corresponding to the level of energy selected by the switches.
