Abstract:

A system for the enhancement of a televised golf broadcast, which requires: obtaining detailed topographic measurements of golf greens; inputting these data into a Geographic Information System (GIS) program, smoothing the data, and generating contours on a selected interval; storing and processing the contour data such that it may be viewed from various other perspectives; selecting a real-time televised image of a golf green from a plurality of camera positions; synchronizing and superimposing the contour database image over the televised feed; computing and processing equations of motion which take into account the location of the golf ball relative to the golf cup, the weight of the golf ball, the effect of the wind, the Stimpmeter speed of the green, and the gravitational influence of the slope of the green, to determine a path the putt can take to roll into the cup or to come to rest within 18 inches of the cup; and displaying the combined images along with the projection of the calculated ball path on a real-time televised broadcasts. Before the golfer strikes the golf ball toward the cup, this system provides the viewer with a visual image of an optimal path the golf ball can traverse to result in a successful putt. With the addition of the contours and the calculated trace of the putt trajectory, the viewer has a visual assessment of the break of the putt, without depending upon the announcers comments.

Abstract:

A hoisting system is disclosed which includes a hoisting drum around which two hoisting ropes are wound in respective hoist rope grooves. The hoisting ropes are secured to the hoisting drum at one end, and extend down to a suspended device, such as an elevator, or a crane hook. The hoisting drum also includes a cable groove, which is located between the two hoist rope grooves. An electrical cable is secured at one end to the hoist drum, is wound around the hoist drum in the cable groove, and extends down to the suspended device. A slip-ring assembly establishes an electrical connection to the cable, so as to permit power to be supplied to the suspended device.
