1. A bowling pin configured for use in a bowling system comprising:
- a body having a base, a neck and a head portion; and
a radio-frequency identification (RFID) tag having a pin antenna, said pin antenna being associated with said body and configured to generate a power signal in response to a reader field, said RFID tag further including a processor responsive to said power signal for activation thereof wherein said RFID tag is configured to produce an identification signal for identifying said pin.

Abstract
An RFID pin detection system includes bowling pins incorporating RFID tags and a pin deck incorporating reader antennas located in positions corresponding to the placement of the bowling pins. A controller energizes the reader antennas to activate RFID tags in those bowling pins that are in the pin-up position. The pin-up information is used in automatic scoring.

34. A bowling pin fall detection system for use with bowling pins placed in a predetermined arrangement on a pin deck wherein each pin includes a respective radio-frequency identification (RFID) tag having a pin antenna and configured to identify said respective pin, said system comprising:
-
a pin detect controller responsive to a pin fall signal to generate a reader antenna activation signal;
a monitor block including an antenna drive circuit responsive to said activation signal configured to energize said reader antennas;
a plurality of reader antennas configured to radiate a respective reader field to a corresponding position in said predetermined arrangement, said reader antennas being further configured to sense modulations in respective reader fields when one of said bowling pins is within a respective range of said radiated positions;
said monitor block further including a filter and amplifier circuit configured to process said sensed modulations from each reader antenna for detecting said bowling pins in a pin-up position and for generating an output signal;
said pin detect controller being responsive to said output signal from said monitor block to generate a pin detection signal indicative of at least one of (i) a number of bowling pins in said pin-up position; and
(ii) a number of pins in a pin-down position. - View Dependent Claims (35, 36, 37)
