Abstract: A hand-held flinging device includes a launcher that engages the projectile and improves control of the launcher and projectile, during a throwing/flinging motion, until centrifugal force causes disengagement of the projectile from the launcher. The engagement system involves the rearward portions of a launcher shaft and the projectile bore, so that, upon disengagement, frictional engagement and interference of the engagement system with the projectile is prevented or limited as the projectile moves forward to fly off the launcher. The engagement system may include a member that snaps into engagement with a hole or recess to hold the projectile on the launcher even through the wind-up portion of the throw that may include the launcher distal end being pointed downward. The preferred projectile covers the entire or nearly the entire launcher shaft distal of the hand grip and is heavier toward its front end.

Abstract: A system and method for selectively controlling an electrical component is claimed. The system contains an audio detector, such as a microphone, that receives sound energy and converts the sound energy into a corresponding electrical signal. The content of the sound energy is irrelevant. Rather, it is the volume of the sound energy that is to be represented by the electrical signal. To produce an electrical signal that corresponds to noise volume, the amplitude of the electrical signal is amplified. The amplified signal is then rectified and filtered, thereby producing a D/C electrical signal that is representative of the volume of the sound energy detected. The D/C electrical signal is used to selectively regulate a current flow controller. The current flow controller controls the flow of current to the electronic component.

A timing cord extending between the vane and the ring enables the vane, once removed, to be spun in the air by a hunter to produce the "Pulmonic Puff" sound of the wild turkey gobble.

Abstract: A method and device are disclosed for expanding the field of application of florescent correlation spectroscopy. The device has a confocal optical structure, a pulsed laser for excitation and components for detection and evaluation of measuring signals for time-correlated single photon counting. The data is registered in such a way that for each detected photon, detection time is recorded in microseconds while fluorescence delay time is recorded in nanoseconds.

Correlation functions of parameters or selective correlation functions, e.g. for fluorescence burning life, are thus obtained.
