Abstract:
An apparatus for analyzing free flight of a body including an inertial measurement unit having at least one accelerometer continuously measuring three orthogonal axes of acceleration and outputting data representative thereof and a processing unit operably receiving the data and determining three components of an angular velocity of the body during free flight.
Abstract:
An apparatus for analyzing movement of equipment. The apparatus includes an inertial measurement unit continuously measuring six rigid body degrees of freedom of the equipment and outputting data representative thereof, wherein the inertial measurement unit defines a planar substrate having a single common plane. The inertial measurement unit further includes at least one angular rate gyro and at least one accelerometer sufficient to measure the six rigid body degrees of freedom and each being mounted on the single common plane. The apparatus further includes a processing unit determining the acceleration of the mass center of the equipment, the angular velocity and the angular acceleration of the equipment through a single derivative operation.

Abstract:
An application of rate gyros and accelerometers allows electronic measurement of the motion of a rigid or semi-rigid body, such as a body associated with sporting equipment including a fly rod during casting, a baseball bat, a tennis racquet or a golf club during swinging. For instance, data can be collected by one gyro according to the present invention is extremely useful in analyzing the motion of a fly rod during fly casting instruction, and can also be used during the research, development and design phases of fly casting equipment including fly rods and fly lines. Similarly, data collected by three gyros and three accelerometers is extremely useful in analyzing the three dimensional motion of other sporting equipment such as baseball bats, tennis racquets and golf clubs. This data can be used to support instruction as well as design of the sporting equipment.

Abstract:
A bird feeding device is disclosed which can be accessed by birds and not by squirrels. The device comprises a container for holding feed and a wire mesh enclosing the container. An o-ring supports the container within the wire mesh and spaces the mesh away from the container such that the mesh is not directly in contact with the container whereby squirrels are prevented from accessing the container.
