Infrared hockey puck and goal detection system

Abstract

The two-part system includes a modified hockey puck and a set of goal units that can be mounted on a hockey goal. Within the puck are light sources, motion sensors, infrared transmitters, and a power source. Within the goal units are light sources, infrared sensors, and a microcontroller. When the goal units are mounted on the hockey goal, the infrared sensors form a detection area through which the puck must pass in order to count as a goal. The infrared transmitter of the puck and the infrared sensors of the goal units communicate with one another, and when an infrared signal is received the microcontroller triggers the light sources mounted to the goal to illuminate and indicate that a goal has been scored. Additionally, both the puck and the goal units are designed to reduce power consumption by switching between a low-energy mode or an active mode of operation.

DETAILED DESCRIPTION OF THE INVENTION

(12) Reference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the infrared hockey puck and goal detection system. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.

(13) Referring now to FIG. 1, there is shown a perspective view of a goal detection system. The goal detection system 1000 comprises a top a top assembly 100, a left assembly 200, and a right assembly 300. In the illustrated embodiment the top assembly 100 is configured to be mounted on the crossbar of a hockey goal, the left assembly 200 is configured to be mounted to the left goal post of a hockey goal, and the right assembly 300 is configured to be mounted to a right goal post of a hockey goal. Once mounted on a hockey goal, these three assembly elements combine with the surface on which the goal rests to define a sensing zone 400 that a hockey puck must pass through in order to be counted as a goal. In other embodiments the top assembly 100, left assembly 200, and right assembly 300 are attached to the hockey goal by means other than mounting, or perhaps could be built directly into the of the hockey goal and circumvent the need to mount entirely.

(14) Referring now to FIG. 2A there is shown a perspective view of a modified hockey puck. In the illustrated embodiment, the modified hockey puck 600 comprises an ingress proof housing 630 having an interior volume 631. Encased within the housing 630 is a first light source 610, a second light source 620, a motion sensor 640, a battery 650, and an infrared transmitter 660. In the illustrated embodiment, the modified hockey puck 600 is composed of vulcanized rubber and includes a sidewall 632 having transparent windows 633 to enhance visibility of the light sources 610 and 620 contained within. In other embodiments, the modified hockey puck 600 may be composed of other materials, and the transparent windows 633 in sidewall 632 may be configured differently. For example, instead of having multiple transparent windows 633 interlaced with frames carved out from sidewall 632, the window 633 is entirely comprised of a monolith transparent material that completely wraps around the circumference of the modified hockey puck 600. In other embodiments, instead of having the light sources 610 and 620 encased within the housing 630, the light sources are embedded directly into sidewall 632, such that irrespective of sidewall's 632 configuration light sources 610 and 620 would remain visible to players and a viewing audience.

(15) In the illustrated embodiment, the modified hockey puck 600 further includes two modes of operation to reduce power consumption and improve overall performance of the hockey system: (i) a passive mode and (ii) an active mode. In the passive mode the modified hockey puck 600 rests in an ultra-low energy consumption state such that only the motion sensor 640 remains active while the first light source 610, second light source 620, and infrared transmitter 660 are all inactive. The modified hockey puck 600 transitions from the passive mode to the active mode upon detection of motion by the motion sensor 640. Once in the active mode the first light source 610 is illuminated, and the infrared transmitter 660 begins transmission of an infrared signal.

(16) In the illustrated embodiment, the motion sensor 640 comprises a shock sensor that is configured to detect a shock signal value change in response to motion of the modified hockey puck 600. More specifically, the active mode is triggered upon detection of a shock signal value above a predefined threshold. Also, the modified hockey puck 600 is configured to transition from the active mode to the passive mode when the shock sensor has not detected a shock signal value over the threshold value for a predetermined amount of time. In other embodiments the motion sensor may be configured to detect motion of the modified puck 600 by other means.

(17) Referring now to FIG. 2B there is shown a cross-section of the modified hockey puck along line 2B. The second light source 620 is activated when a voltage of the battery 650 drops below a predetermined uncharged threshold value in order to indicate that the battery 650 requires charging. More specifically, upon activation the second light source 620 is configured to flash intermitently such that the flashing will increase in frequency as the voltage of the battery 650 continues to decrease below the predetermined uncharged threshold value.

(18) In the illustrated embodiment, the battery 650 powering the modified hockey puck 600 includes an inductive receiver coil (not shown) that is configured to receive radiofrequency energy and to produce a charging voltage for charging the battery inductively or wirelessly. The battery 650 further includes a voltage regulator (not shown) for preventing overvoltage charging of the battery, such that the voltage regulator is activated when the voltage of the battery acquires a predetermined charged threshold value. Once the battery 650 has stored charge equivalent to the predetermined charge threshold value the second light source 620 is deactivated and the first light source 610 is activated to indicate that the battery 650 has finished charging. In other embodiments the modified hockey puck 600 may include other means of accumulating charge in a rechargeable battery or alternately the modified hockey puck 600 may include a different means supplying power such as disposable batteries.

(19) Referring now to FIG. 3 there is shown an exploded view of a goal detection system. In the illustrated embodiment, the top assembly 100 of the goal detection system 1000 comprises a microcontroller 531 and a third light source 110, the left assembly 200 comprises a fourth light source 210 and a first infrared sensor 220, and the right assembly 300 comprises a fifth light source 310 and a second infrared sensor 320.

(20) In the illustrated embodiment of the goal detection system 1000 the top assembly 100 is operably connected to the left assembly 200 and the right assembly 300, such that the first and second infrared sensors 220, 320 face the interior of the goal forming a sensing zone 400 (not shown) across a goal line of the hockey goal when mounted. Furthermore, the first infrared sensor 220 and the second infrared sensor 320 are configured to detect the infrared signal emitted by the infrared transmitter 660 (not shown) when modified hockey puck 600 (not shown) crosses the sensing zone 400. The microcontroller 530 is activated upon detection of the infrared signal crossing the sensing zone 400 by infrared sensors 220 and 320. Consequentially, activation of microcontroller unit 530 then triggers activation of the third light source 110, the fourth light source 210, and the fifth light source 310 in order to indicate that a goal has been scored. More specifically, the goal detection system 1000 further comprises a comparator, such that any crossing of the infrared signal transmitter 660 across the sensing zone 400 will cause a voltage drop across the infrared sensors 220 & 320, which will in turn cause the comparator to drop below a predetermined sensing voltage threshold and activate the microcontroller unit 530.

(21) Other embodiments of goal detection system 1000 and modified hockey puck 600 employ radio frequency transmitters and receivers outside of the range infrared frequencies, or alternatively rely on a form of signal transmission and detection other than radio frequency technology.

(22) Referring now to FIG. 4A there is shown an exploded view of a top assembly for the goal detection system. The top assembly 100 comprises a first unit 130 and a second unit 140 interconnected at a control box 500 (as seen in FIGS. 4B and 4C).

Furthermore, the first light board 132 and the second light board 142 each include a plurality of LEDs 160 conjunctively defining the third light source 110. The first light board cover 133 and second light board cover 143 each include a plurality of transparent windows 170 corresponding to the plurality of LEDs 160, such that when the third light source 110 is activated the light emanated can more easily pass through the top assembly 100 and be visible to onlookers from a distance. Lastly, the control box 500 comprises a mounting plate 501, a battery cover 502, and a lower housing 505, such that the lower housing 505 houses a microcontroller 530, a power supply 510, and a power switch 520 operably coupled to the power supply 510. Other embodiments may be configured differently. For example, each unit 130 and 140 of top assembly 100 are configured to comprise more or less mounting elements, LEDs, electronic components to add functionality, optimize performance, or reduce production costs.

(25) Referring now to FIGS. 4B and 4C, there are shown a plan view of a top assembly for the goal detection system and a front view of a top assembly for the goal detection system, respectively. In the illustrated embodiment of the goal detecting system 1000, the first unit 130 is connected to a first side 503 of the control box 500 and the second unit 140 is connected to a second side 504 of the control box 500 altogether forming the top assembly 100, such that the control box 500 is positioned centrally therealong. Other embodiments may be configured differently. For example, the top assembly 100 is not subdivided into two units 130 and 140 separated by the control box 500. Instead the top assembly could be a single unit to which the control box 500 is affixed by some other means.

(26) Referring now to FIG. 4D there is shown a cross-section of a control box along line 4D. In the illustrated embodiment, the control box 500 comprises a power supply 510, a power switch 520, a microcontroller unit 530, and a power indicator 540.

(29) Referring now to FIG. 6 there is shown an exploded view of a left assembly for the goal detection system. In the illustrated embodiment the left assembly 200 comprises a third mounting bracket 201, a third light board 202, a third light board cover 203, and a third mounting cover 204, such that the third light board 202 and the third light board cover 203 are further sub-divided into three sections: a, b, and c. Furthermore, the sub-divisions 202a, 202b, and 202c of the third light board 202 are mountably affixed to the corresponding sub-divisions 203a, 203b, and 203c of the third light board cover 203.

(31) Referring again to FIG. 3 there is shown an exploded view of a goal detection system 1000. The goal detection system 1000, similar to the modified hockey puck 600, further includes two modes of operation to reduce power consumption and improve overall performance of the hockey system: (i) a passive mode and (ii) an active mode. In the passive mode the goal detection system 1000 rests in an ultra-low energy consumption state such that only the power indicator 540 of control box 500, and infrared sensors 220 and 320 of left assembly 200 and right assembly 300 remain active while the microcontroller unit 530 of control box 500, third light source 110 of top assembly 100, fourth light source 210 of left assembly 200, and fifth light source 310 of right assembly 300 are inactive.

In this embodiment, the light sources 110, 210, and 310 comprise addressable, multi-color LEDs 170, 270, and 370, such that when a goal is scored and the infrared signal from the infrared transmitter 660 is detected by the infrared sensors 220, 320, the microcontroller unit 530 will send a signal to light all of the LEDs to a solid red color enveloping the mouth of the hockey goal on all three sides for all players and spectators to recognize. Furthermore, the light sources 110, 210, and 310 employ a pulse width modulation (PWM) method that allows the LEDs 170, 270, and 370 to oscillate between on and off states at a frequency that is imperceptible to the human eye. Utilization of the PWM method will reduce power consumption and improve the overall performance of the hockey system. In other embodiments the light sources 110, 210, and 310 may employ a lighting technology other multicolor LEDs and may utilize a methodology other than PWM.

(33) It is therefore submitted that the instant invention has been shown and described in various embodiments. It is recognized, however, that departures may be made within the scope of the invention and that obvious modifications will occur to a person skilled in the art. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

(34) Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
