DETAILED DESCRIPTION OF THE INVENTION

[0014] Referring now to the drawings and in particular FIGS. 1 and 2, an embodiment of a sound emitting trackable arrow 10 is shown having a shaft 11 defined by an elongated cylindrical member having a proximal end and a distal end. In one embodiment, the shaft 11 is sized and shaped to receive an insert member 12 as a distal member into the distal end and a nock member 13 as a proximal member into the proximal end such that each of the insert member 12 and the nock member 13 may be frictionally secured in place and/or otherwise fixed in place. In this regard, the shaft 11, insert member 12 and nock member 13 may form the principle elements of an assembled arrow (not shown) suitable for shooting from a bow (not shown). As with many modern assembled arrows, an arrowhead may be mountable to the insert member 12.

[0015] In the front wireless tracking embodiment, the insert member 12 additionally includes a wireless tracking component 14 coupled therewith, positioned relative to the insert member 12 such that the wireless tracking component 14 will be fully enclosed inside the shaft 11 when the insert member 12 is inserted into the shaft 11. The wireless tracking component 14 includes an onboard power source 15, a controller 16, a wireless beacon 17, an antenna 18, and a speaker 19, each of which are electrically interconnected to allow the power source 15 to supply electricity to the other components and the controller 16 to control the operation of the other components. In one embodiment, a Bluetooth low energy beacon defines the wireless beacon 17. In this regard, the wireless tracking component 14 is configured to broadcast an identifier and a Measured Power value to a nearby portable electronic device through the wireless beacon 17, receive wireless electrical signals through the antenna 18, and send an electrical signal from the controller 16 to the speaker 19 which causes the speaker 19 to emit an audible sound. It is contemplated that the Measured Power value provides a signal strength value which in one embodiment, represents the expected Received Signal Strength Indicator at a distance of one (1) meter to the beacon.

[0016] In one embodiment, the remote tracking device 20 is defined by a conventional mobile computer device, such as a smart phone or tablet, that includes a Bluetooth interface that allows it to receive wireless transmissions from the wireless beacon 17 and read a Received Signal Strength Indicator (RSSI) for incoming transmissions, a wireless transmitter that allows it to send electrical signals wirelessly to the antenna 18, and a user interface that allows it to receive an input from a user that commands the sending of the electrical signal to the antenna 18 and generate an output related to the approximate distance of the wireless beacon 17 from the remote tracking device 20. In one embodiment, the remote tracking device 20 includes a software application that provides the instructions to its electronic components for the performance of such operations, as well as for the calculation of approximate distance between the wireless beacon and the remote tracking device based on a Measured Power value received and an RSSI reading.

[0017] In the operation of embodiments in which the wireless beacon 17 and the antenna are always powered, as long as the power source 15 is energized, the wireless beacon 17 periodically emits a wireless signal that contains its identifier and Received Measured Power value so as to allow a remote tracking device 20 to receive and monitor signals from the wireless beacon 17 and enable the identification of the wireless beacon 17 and a real time approximation of the distance between the wireless beacon 17 and the remote tracking device 20. As such, once a user shoots an assembled sound emitting trackable arrow 10 built in accordance with the present invention (i.e., an arrow having a wireless tracking component 14 with a monitored wireless beacon 17), the remote tracking device 20 continually maintains a determination of the approximate distance of the arrow 10 based on a comparison of the Measured Power value of the wireless beacon 17 and the RSSI reading observed by the remote tracking device 20. This real time approximate distance determination allows a user holding the remote tracking device 20 to know whether they are walking towards the arrow 10 or away from the arrow 10 (and thus ensure they are moving closer to the arrow).

[0018] As a user seeking to recover the arrow 10 moves closer to the arrow 10, as evidenced by the approximate distance output of the remote tracking device 20, the user may actuate the interface of the remote tracking device 20 to cause it to send a wireless electrical signal to the antenna 18 inside the arrow 10. In one embodiment, this wireless electrical signal includes a command that causes the controller 16 to send a signal to the speaker 19 that causes the speaker 10 emit an audible sound. As such, if this signal from the remote tracking device 20 is received, the arrow 10 will begin to emit an audible sound that, in addition to following the distance readout on the remote tracking device 20, makes it even easier to move towards the arrow 10 and locate and recover the arrow 10.

[0019] In one embodiment, the antenna 18 defines an RF antenna and the remote tracking device 20 transmits an RF signal as the wireless electrical signal to the antenna 18 inside the arrow 10.

[0020] In one embodiment, the power source 15 is defined by a battery. In other embodiments, the power source 15 includes a rechargeable battery and an induction coil operative to take power from an electromagnetic field generated from electricity by an external induction coil in close proximity and covert the field back into electric current to recharge the rechargeable battery.

[0021] Referring now to FIG. 3, in the rear wireless tracking embodiment, a sound emitting trackable arrow 30 also includes a shaft 31, insert member 32 and nock member 33 that form the principle elements of an assembled arrow (not shown) suitable for shooting from a bow (not shown). In the rear wireless tracking embodiment however, the nock member 33 includes a wireless tracking component 34 coupled therewith, positioned relative to the nock member 33 such that the wireless tracking component 34 is enclosed inside the shaft 31 when the nock member 33 is inserted into the shaft 31. As with the front wireless tracking embodiment, the wireless tracking component 34 in the rear wireless tracking embodiment includes an onboard power source 35, a controller 36, a wireless beacon 37, an antenna 38, and a speaker 39. Each of the electrical components of the wireless tracking component 34 are interconnected in the same manner as in the front wireless tracking embodiment, and when operating with a remote tracking device configured in accordance with the present invention, operate in the same manner as in the front wireless tracking embodiment.

[0022] In one embodiment, the wireless tracking component may additionally include an accelerometer which is electrically interconnected with the power source and the controller and operates to transmit an electrical signal to the controller in response to a sudden increase or decrease in acceleration of the wireless tracking component (and thus the arrow in which the wireless tracking component is housed). In such an embodiment, the controller responds to the receipt of the acceleration driven electrical signal by supplying power to the wireless beacon and/or the antenna of the wireless tracking component, which in such an embodiment would not be supplied power when manufactured and/or sold. Accordingly, stored electrical power in the power source would be conserved because the wireless beacon and the antenna would only begin to draw substantial electrical power from the power source when the arrow housing such a wireless tracking component was shot from a bow (as a sudden increase in acceleration) or came to rest after being shot (as a sudden decrease in acceleration).

[0023] It is appreciated that the threshold value of acceleration required to cause the controller to activate the wireless beacon and the antenna would be stored in firmware or other software stored on or accessible to the controller.

[0024] In one embodiment, the wireless tracking component may additionally include a shock detector which operates to generate an electrical signal in response to a physical shock or impact being sustained. In such an embodiment, the controller responds to the receipt of the shock driven electrical signal by supplying power to the wireless beacon and/or the antenna of the wireless tracking component, which in such an embodiment would not be supplied power when manufactured and/or sold. Accordingly, stored electrical power in the power source would be conserved because the wireless beacon and the antenna would only begin to draw substantial electrical power from the power source when the arrow housing such a wireless tracking component impacted an object after being shot.

[0025] The instant invention has been shown and described herein in what is considered to be the most practical and preferred embodiment. It is recognized, however, that departures may be made therefrom within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
