Abstract: A ferrule mounted on one end of a billiard/pool cue shaft has greater compressibility than the compressibility of the shaft to compress on impact of a tip mounted on the ferrule with a ball to absorb a portion of impact forces and to provide easy outward flexure with minimal buckling of the end of the shaft during impact. A bore extends a predetermined distance from the one end of the shaft toward a butt end of the shaft. The bore in the shaft communicates with a bore in the ferrule when the ferrule is mounted on the shaft. The ferrule is mounted on the shaft by means of a tenon formed on one end of the shaft or on the ferrule, which tenon tightly engages the other of the ferrule or shaft. The tip has a smaller than conventional radius to centralize impact forces toward the line of stroke extending along the longitudinal axis of the shaft.

Abstract: A ski simulator apparatus is provided in which two rebounders or miniatures trampolines are maintained and secured in a common framework. The rotatable frame members supporting each trampoline are adjustable to vary the incline of one trampoline relative to the other so as to simulate different size and shapes of moguls. The framework includes receptacles for accepting and securing the legs of conventional rebounders or trampolines therein. The entire unit may be disassembled by removing trampolines and folding the framework upon itself to facilitate storage and transportation.

Abstract: A self contained sensor apparatus generates a signal that corresponds to at least two of the three orientational aspects of yaw, pitch and roll of a human-scale body, relative to an external reference frame. A sensor generates first sensor signals that correspond to rotational accelerations or rates of the body about certain body axes. The sensor may be mounted to the body. Coupled to the sensor is a signal processor for generating orientation signals relative to the external reference frame that correspond to the angular rate or acceleration signals. The first sensor signals are impervious to interference from electromagnetic, acoustic, optical and mechanical sources. The sensors may be rate sensors. An integrator may integrate the rate signal over time. A drift compensator is coupled to the rate sensors and the integrator. The drift compensator may include a gravitational tilt sensor or a magnetic field sensor or both.

Abstract: A reed type of game call for attracting waterfowl, other birds and animals, the preferred embodiment particularly adapted for use in calling ducks. Raised ridges or ribs along the tone board surface operatively support the reed and thereby reduce reed malfunction caused by accumulation of moisture from condensate, saliva and spittle. The operator of the game call thus also has better control over the tone produced during repeated operation on a given occasion. The raised ridges, combined with an O-ring-type seal between the mouthpiece and sound assembly and a reed which tapers in width toward its distal end, permit the game call to be operated with less blowing effort by the caller.

Abstract: A toy figure includes a body, a pair of wings, a pair of legs, a tail, and a head converted to generally resemble a bird or other flying creature. The legs and wings are pivotally mounted to the body using a mechanism by which the pivotal movement of the legs in response to the user squeezing and releasing them repeatedly produces a corresponding wing-flapping action. A spring urges the wings to a raised position and urges the legs to a spread position. The head is pivotally supported by the body and a cam follower and cam arrangement couples the head to the wing movement apparatus such that the head moves side-to-side simultaneous with the wing-flapping movement.
