Abstract: An apparatus for uniquely identifying a golf ball at a target includes a simulated golfing green having one or multiple target area apertures therein. A ball collector is mounted under each aperture. A ball identification means cooperates with the ball collector for identifying uniquely identified game balls from non-uniquely identified golf balls and transmits identity information corresponding to each game ball of the game balls to a remote processing station for correlating the identity of a golfer with the identity information. A surveillance means cooperates with the first target area so as to provide for remote monitoring of the first target area. A first signal means is provided for signalling the golfer and a remote monitor when a uniquely identified game ball has entered the aperture. A first sensor means is provided for detecting when a uniquely identified game ball lands in the first target area and for signalling the golfer and a remote monitor upon such detection.

Abstract: Down-hole information from rotary well drilling operations is transmitted to a surface or remote location by the venting of drilling fluid from the interior of the drill stem into the bore hole annulus in a binary coded decimal format. A valve is caused to operate by the digital output of one or more down-hole transducers thus releasing and restoring the drilling fluid pressure in the desired sequence. A "sub" contains the necessary electronics, power supply and a motorized valve assembly. Commands from the surface to transmit information from any one of the transducers are transmitted by means of sequential pulses in a binary coded decimal format, in the drilling fluid pressure are provided by the operator by deliberately decreasing and then increasing the surface pump pressure in a sequence to which the applicable down-hole actuating means is responsive.
