Abstract: A device for measuring the movement of a ball is a flat pad or a frame defining an opening with one or more magnetic field inducing elements mounted thereon. One or more sensor elements are mounted in the flat pad or the frame, and connected to instrumentation so as to record induced, time-varying current signals from disturbances in a magnetic field by the ball penetrating the field. The device may also be arranged so as to measure the spin characteristics and other vectors of a conductive, charged and/or magnetized golf ball penetrating field. Or, the device may be arranged so as to have no magnetic field inducing elements, whereby the magnetic field of a modified, magnetized golf ball, when passing through an opening, or over a flat pad, induces time varying current signals in at least one sensor element, which can be processed to predict the complete ball flight parameters, i.e., velocity, trajectory and spin.

The system utilizes a radio frequency device having receiving and transmitting means connected between the serial port of the personal computer and various sensors to input signals to the non-data pins of the serial port whereby software in the personal computer interprets the signals received at the non-data pins to place a call to a pager or cellular phone, or communicate with another computer, produce sound effects, and/or operate video equipment.

Abstract: This invention relates to a device for forming a mist or fog having a convex surface which receives and expands a fluid delivered thereto. The convex surface of the device has a number of circular protrusions spaced peripherally thereon, separated by a number of slots having holes therein. The holes communicate with an inner cylindrical chamber. Suction is produced through the holes when the fluid stream passes over them, to automatically add a further fluid to the fluid being expanded by the device. A cylindrical sleeve surrounds and protects the device. The device is supported in the cylindrical sleeve, either in front of a nozzle by an annular structure, or by a bent tube held in the cylindrical sleeve in front of the device, or in a venturi.
