A preferred embodiment of the invention will now be described by way of example only and with reference to the Figures in which:
Referring to the Figures, a golf ball locator apparatus 1 comprises an RFID reader 2. The RFID reader 2 comprises a housing 4 comprising a lower face 6, and opposed upper face 8, and side portions 10 extending therebetween. A cavity 12 is defined between the inner surfaces of the upper face 8, lower face 10 and side portions 10. The housing 4 is composed of plastic, for example ABS plastic thereby providing a light weight housing. The housing 4 is shaped and profiled to largely correspond to a head of a golf club.
The RFID reader 2 further comprises an antenna 14 configured to generate a high frequency electromagnetic field.
The antenna 14 is located within the cavity 12 and positioned adjacent the lower face 6 of the housing 4. The antenna 14 is held in positioned by a pair of antenna braces 16, in the form of bent sheet metal, against the lower face 6 of the housing 4.
The RFID reader 2 further comprises three signal devices 18, 20, 22 operable to provide a signal to a user when the antenna 14 has detected the golf ball. The three signal devices 18. 20 and 22 are provided in the form of LEDs located on the upper face 8 of the housing 4. It is however to be understood that other signal devices may be used, for example audio signal devices or a combination of audio and light signal devices.
The first signal device 18 is a red coloured LED and operable to be illuminated when the power level of the power source 24 is below a predetermined level thereby providing a visual indication to the user that the RFID reader requires charging.
The second signal device 20 is a green coloured LED and operable to be illuminated when the RFID reader has detected a RFID tag in the nearby vicinity.
The third signal device 22 is a white coloured LED and operable to be illuminated when the RFID reader is in use to provide an indication to the user that the antenna is in operation.
The RFID reader 2 further comprises a power source 24 in the form of a battery operable to provide power to the antenna and signal device.
The power source 24 is located within the cavity 12 housing 4. The housing 4 further provides a charging port 26 in the form of a USB charging port in communication with the power source 24. The charging port may comprise a rubber plug 25 to prevent water and dirt ingress.
The housing 4 seals the antenna 14 and power source 24 from an external environment thereby protecting these components against water ingress into the cavity 12.
The RFID reader 2 further comprises a magnet 28 located on a side portion 10 of the housing 4. The magnet 28 being sized and shaped for attachment to a head of a golf club. Although the illustrated embodiment has a single magnet it is to be understood that the RFID reader may comprise any suitable number of magnets. It is also to be understood that the RFID reader may comprise any suitable number and types of attachment features and is not limited to the use of magnets.
The apparatus 1 further comprises a passive RFID tag 30 in the form of a planar circular tag having an upper surface 32 and an opposed lower surface 34. An adhesive layer is provided on the lower surface 34 of the tag for engaging the tag 30 to a golf ball 36.
In use, the user locates a passive RFID tag 30 and adheres the lower surface 34 to a golf ball.
Once the ball is lost within for example long grass, the user attaches the RFID reader 2 to the head of a golf club by securing the magnet 28 to the head.
The user then walks around the area that the golf ball is lost in and moves the golf club in a sweeping action similar to a metal detector. As the RFID reader 2 sweeps through the area, the antenna is sending out a high frequency electromagnetic field. Once the RFID reader 2 detects the presence of the tag 30 within an area, the second signal device 20 provides a clear visual indication that the tag 30 has been found.
The present invention therefore provides an efficient and easy apparatus for locating lost golf balls.
The passive RFID tag may have any size and shape suitable for being placed onto a golf ball. For example the RFID tag may be selected from, but not to be limited to, square, rectangular, oval, polygonal, triangular, circular or semi-circular in shape.
The passive RFID tag is preferably planar in shape to ensure that on application to a golf ball that the RFID tag cause minimal aerodynamic impact. The passive RFID tag preferably comprises an upper surface and an opposed lower surface.
Preferably, the thickness of the locator (as measured between the upper and lower surface) is kept to a minimum in order to minimise any resultant aerodynamic impact.
The upper surface may comprise any suitable surface decoration for example logos, names, designs etc such that a user can recognise their golf ball on sight.
The lower surface preferably comprises an adhesive layer for adhesion to a surface of a golf ball. The adhesive layer may be continuous or may be discontinuous across the lower surface.
The passive RFID tag may be provided on a sheet containing a plurality of passive RFID tags, for example a sheet comprising a plurality of adhesive RFID tags.
In use, when a user has misplaced a golf ball, for example in the rough, the user can secure the RFID reader to the head of the golf club. The user can then move the club in sweeping movements across the grass, in a similar manner to a metal detector, until the RFID reader provides a signal from the signal device providing an indication that the golf ball has been located.
Preferably, the range of the RFID reader (as measured between the distance of the antenna and the RFID locator) is up to 5 m. The apparatus can therefore be used to find a lost golf ball within a reasonable range with confidence. In another embodiment the apparatus can be modified to a live tracking device. This enables an imager or other tracking means to follow a golf ball, after having been struck by the golf club, to its end location.
The invention has been described by way of examples only and it will be appreciated that variation may be made to the above-mentioned embodiments without departing from the scope of protection as defined by the claims.
