Abstract: A motion sensing device with both inertial sensors and optical elements that integrates into a piece of sports equipment. Equipment with the device installed may look and feel like the original equipment. For example, for a baseball bat, a sensor package with a housing containing inertial sensors, cameras, and lights may be integrated into a knob that can be swapped with a standard bat knob; an additional sensor package may be integrated into a replacement bat cap. Sensor data and images from cameras in the device may be transmitted to a processor that calculates the equipment trajectory. External cameras may also capture images of lights in the device, which may flash or change in a pattern that is synchronized with the sensor data, and these images may also be used in trajectory calculations. Equipment with the motion sensing device may be used for virtual reality or for real sport activities.

Abstract: A film transfer and edit adaptor for facilitating the moving, reviewing and editing on spindle capable systems of a film set up for platter system projecting equipment, the adaptor including a support plate for the film, a cover plate for protecting the film, at least one fastening means for removably securing the cover plate to the support plate, a stem having sidewalls and a central bore, the central bore slidably engageable with the spindle system, and a locking means for lockingly engaging the stem with the spindle system.

Abstract: A container for shipping and handling a motion picture film of feature length ready for projection using turntable-type projection equipment without the need for splicing or cutting the film. The device has spaced upper and lower main walls with central openings, an inner ring between the main walls removably secured to the lower wall and providing for film attachment, an outer annular wall extending between the main walls near the peripheral edges and preferably an inner annular wall near the central openings, and devices drawing the main walls together to close the container. Preferred embodiments have the outer and inner annular walls affixed to the upper wall such that the lower main wall forms a substantially flat disk without substantial projections, to facilitate film removal and rewinding during first and last showings of the film at a theater. Other features relate to inner ring characteristics aiding attachment and removal.
