Abstract: A method is provided for determining a location to place a mass on a wheel assembly. A first set of acceleration data is collected from a plurality of inertial measurement units (IMU's) that are mounted to a removably attachable object that is attached to a wheel of the vehicle in a manner that inhibits the object from coming off of the vehicle when the vehicle is in motion. The first set of acceleration data is collected while operating the vehicle at a first speed. The first set of acceleration data is used to determine an offset between a center of the object and a bearing center of the wheel assembly. A second set of acceleration data is collected from the plurality of inertial measurement units (IMU's). The second set of acceleration data is collected while operating the vehicle at second speed that is greater than the first speed.

Abstract: An orthopaedic surgical instrument includes a patella trial and drill guide that may be used to both perform a surgical trial of the patellofemoral joint and guide the surgeon in drilling a number of anchor holes in the patella of the patient.

Abstract: A coloring kit is disclosed which includes writing instruments for making marks in color, a storage container for the writing instruments, and a compact disc that has instructions for reproducing displays of interactive activities utilizing the writing instruments from a personal computer. The interactive activities may include a coloring book or similar such activities. The end user or customer may print physical copies of the displays from a personal computer coupled to a printer. In some embodiments, the storage container may also enclose and store the compact disc.

Abstract: The present invention provides a virtually spill-proof container for use with paint or liquids of comparable viscosity. In particular, the container of the present invention comprises a receptacle having a base portion and a top portion, an insert member with a generally central aperture attached to the top portion of the receptacle, and a barrier member having a hole formed therethrough operatively connected to the insert member. The hole in the barrier member permits a user to access the liquid within the container with a brush or like instrument, while the barrier member functions like an obstruction which prevents, or minimizes, spillage should the container be tipped over or inverted. The barrier member may alternatively be constructed of an absorbent sponge or solid plastic material. A lid is also provided so that the user may conveniently open and reseal the container.
