A combination of a bellows structure (12), volume restrictor, and pressure restrictor for use on a hand-operated resuscitator is provided to enable delivery of ventilation within specific volume and pressure limitations specified by the operator. The bellows structure (12) consistently provides predictable and uniform generation of gas flow for ventilation without regard to one or two-handed technique, hand placement, or hand size. The volume restrictor, primarily comprising of an inflow obturator (20), outflow obturator (22), and placement cam (34), enables the physician to specify a specific tidal volume to be delivered, which constitutes a volume-controlled cycling capability of the invention. The pressure restrictor, primarily comprising of an outer housing (40), stopper housings (41), and a stopper (50), enables the physician to specify a specific maximum airway pressure to be exposed to the patient, which constitutes a pressure-controlled cycling capability of the invention. Combined use of the volume and pressure restricting mechanisms can provide for various additional abilities, including limiting airway pressure during volume-controlled ventilation or providing a means to detect decreasing pulmonary compliance.

Logic of a handheld controller can implement sensor fusion algorithms based on force data provided by a force sensing resistor (FSR) in combination with touch data or proximity data provided by a touch sensor or an array of proximity sensors, respectively. An example sensor fusion algorithm can be used to re-calibrate the FSR when an object contacts an associated control, as detected by the touch sensor. Another example sensor fusion algorithm can be used to ignore spurious inputs detected by the FSR when an object is in contact with an adjacent control. Another example sensor fusion algorithm can be used to detect a hand size of a hand grasping a handle of the controller, as detected by the array of proximity sensors, and to adjust the threshold force to register a FSR input event at the FSR according to the hand size.

The present invention is a modified glove with control / grip-enhancing and perspiration retention properties, offering the bowler a range of functions and options specific to the individual bowler's abilities, equipment selection (i.e. bowling ball), and the lane conditions faced. An elastomeric, control / grip-enhancing material circumferences the fingertips of at least one finger, providing a similar shape and feel to the commonly used, cylindrical inserts / grips; the glove designed to be used in lieu of finger inserts. The present glove invention can be interchangeable between right and left-handed bowlers of approximately the same hand size. The perspiration retentive fabric combined with the elastomeric, control / grip-enhancing material eliminates or significantly reduces perspiration from an otherwise naked inserted finger, which normally has contact with the hole(s) of a bowling ball. Consequently, the present glove invention results in more consistent control and release of the ball off the hand, increased ball energy, increased ball motion and revolution potential, a higher impact between ball and pins, leading to more lively pin scattering, all of which ultimately results in higher scoring potential. Functionality and performance characteristics of various embodiments of the glove invention provide the bowler a range of control / grip-enhanced, textured and non-textured surface materials at the fingertip area of the glove. Likewise, the control / grip enhanced material of the palm area of the glove works to grip the surface of the bowling ball. The ball position in the cupped and gloved hand is maintained even though the bowler moves his / her hand slightly either away from towards or laterally with respect to the bowling ball. Embodiments of the glove invention offer the bowlers a variety of options for the fingers, as well as for support around the wrist area.

An adjustable pistol grip for improving the accuracy of detachable pistol grip firearms, including rifles, improves the ergonomics for the trigger and pistol grip. The pistol grip is user-adjustable and useable for a larger range of hand sizes. The improvement to provide adjustability allows for proper hand and finger positioning providing improved trigger control to the user.

A hand weight with a central grip area and contoured opposing weight portions at the ends so as to convey a “Z”-shaped profile. The asymmetry of the hand weight results in a shape that is more open to accommodate a larger range of hand sizes and to more comfortably fit into the hand for a variety of holds. The shape of the end portions also results in an overall shape that is less obstructive of movements since it has a narrower profile when rotated appropriately. One of the ends is configured with a flat section to enable the weight to be positively and stably set on a flat surface and prevent rolling.

A personal mask testing system (PMTS) is of a size of a human hand. The PMTS has several energy efficient features that permit running the PMTS from a battery source within the housing. The PMTS also includes a replaceable vapor source.
