DESCRIPTION OF THE PREFERRED EMBODIMENTS

(14) A billiards game may typically start by lagging, which is a process to determine which player will go first to start the actual billiards game. The winner of the lag determines who goes first.

(15) Regardless of the type of billiards game, the lag process typically involves each player lining up their ball near the head rail of the billiards table, and trying to return the ball as close as possible to the head rail after bouncing off the foot rail. The player whose ball stops closest to the head rail wins the lag, and gets his/her choice of whether to shoot first or require his/her opponent to shoot first. For many games, the lag winning player will want to shoot first. However, for some games, such as straight pool, the lag winner may want to go second in order to force his/her opponent break up the rack.

(16) Referring now to FIG. 1, a top-down view of a billiards table 100 indicating a lag process is shown. Table 100 includes head rail 102, foot rail 104, side rail 106, and side rail 108. Table 100 includes six pockets, indicated generally as 110. As previously stated, some billiards tables do not have pockets. Embodiments of the present invention are well-suited for both pocket, and carom (no pockets) billiards.

(17) To begin the lag process, a first player may place a billiard ball at a location 112S, and then strike the ball with a cue, forcing the ball to travel along path P1, striking the foot rail 104, and bouncing back towards the head rail 102, coming to a rest at position 112F, which is a distance D1 from the head rail 102. Similarly, a second player may place a billiard ball at a location 114S, and then strike the ball with a cue, forcing the ball to travel along path P2, striking the foot rail 104, and bouncing back towards the head rail 102, coming to a rest at position 114F, which is a distance D2 from the head rail 102. In this example, since D2 is less than D1, the second player has won this lag, and thus gets to decide which player will start the game.

(18) FIG. 2 illustrates a top-down view of a billiards table 200 after both players have performed a lag process, and illustrates a close lag. In this example, a first player has performed a lag attempt and positioned his ball 212 at a distance D3 from head rail 202. Similarly, the second player has also performed a lag attempt and positioned his ball 214 at a distance D4 from head rail 202.

(19) Referring once again to the example illustrated in FIG. 1, player 2 was the clear winner, since D2 is considerably less than D1.

(20) However, in the example of FIG. 2, it is difficult to manually determine the winner, since the difference between D3 and D4 is quite small as compared with the difference between D1 and D2 of FIG. 1. With experienced players, who are skilled at positioning a ball near the head rail, it can therefore be challenging to manually determine which player won a lag. Thus, embodiments include determining the winner as a player that used the billiard ball that received the incident light from the illumination source.

(21) FIG. 3 illustrates a use of a lag winner determination device 300 in accordance with an embodiment of the present invention. The lag winner determination device 300 includes an illumination source 302 which outputs a narrow light beam 304. The lag winner determination device (LWDD) 300 is placed along the side rail 206, such that the light beam 304 is oriented parallel to a long dimension of head rail 202. The light beam starting orientation is closest to the head rail 202 as possible. Then the illumination source 302 is gradually moved away from the head rail 202. This can be accomplished by moving the entire device 300 along the side rail 206, or moving the illumination source 302 within the device 300. The light beam 304 illuminates the ball that is closest to the head rail first as it is moved away from head rail 202. In this example, it can be seen that the second player, using ball 214 is the lag winner, since ball 214 is illuminated by light beam 304 while ball 212 of player 1 is not illuminated by light beam 304. Hence, disclosed embodiments enable accurate determination of a lag winner.

(22) In some embodiments, the illumination source (light source) includes a laser. In embodiments, the laser comprises a helium-neon gas laser. In other embodiments, the laser comprises a diode laser. In still other embodiments, the laser includes a diode-pumped solid state laser. In some embodiments, the laser is configured to output light with a wavelength ranging from 400 nanometers to 750 nanometers. In some embodiments, the laser is configured to output light with a wavelength ranging from 495 nanometers to 570 nanometers, corresponding to green light. In some embodiments, the laser is configured to output light with a wavelength ranging from 620 nanometers to 750 nanometers, corresponding to red light. In some embodiments, the laser is configured to output light with a wavelength ranging from 450 nanometers to 494 nanometers, corresponding to blue light. These example wavelength ranges are non-limiting, and other colors of light may be used in some embodiments.

(23) FIG. 4 shows details of a top-down view of a lag winner determination device in accordance with an embodiment of the present invention. Device 300 includes an enclosure 307. Disposed within the enclosure 307 is a power switch 320, and a light source (illumination source) 322 disposed on the light side 324 of the enclosure 307.

(24) FIG. 5 shows details of the light side view of lag winner determination device 300 shown in FIG. 4. In this view, the power switch 320 is shown on the top surface of the enclosure 307. The power switch 320 may include, but is not limited to, a pushbutton switch, toggle switch, capacitive touch switch, or other suitable switch. The switch may be a momentary-on switch in some embodiments. Thus, in some embodiments using a pushbutton switch, the switch may only be on while a user is pressing the pushbutton switch. When the switch 320 is in the on position, the light source 322 is activated to emit light. In some embodiments, the light source 322 may be moveable along a rail 326. In some embodiments, a groove, or other guidance mechanism may be used instead of, or in addition to, the rail 326. The rail allows movement of the light source to determine the lag winner.

(25) FIG. 6 shows details of a side view of a lag winner determination device 340 in accordance with another embodiment of the present invention. Device 340 is mostly similar to device 300 shown in FIG. 5, with the key difference being the use of a first light source 344 and a second light source 346 affixed to a light source bracket 342. In embodiments, the first light source 344 and the second light source 346 each emit light of a different wavelength, thus offering the possibility of using two colors of light. While in some cases, a lag may be performed using two white cue balls, in some cases, colored balls may be used. In such cases, some colors of light may be more easily visible on a given billiard ball, depending on its color.

(26) For example, red light may be easier to see on a green billiard ball, while green light may be easier to visually identify on a red billiard ball. Thus, with the embodiment shown in FIG. 6, improved performance of the device may be realized by using various colors of billiard balls for the lag. Additional the embodiment of FIG. 6 can be beneficial when a user has any form of colorblindness where he/she is more sensitive to light of a particular color.

(27) In embodiments, the first light source is a laser and is configured to output light at a first wavelength, and the second light source is a second laser is configured to output light at a second wavelength. In embodiments the laser and the second laser are oriented such that a light beam from the laser is oriented parallel to a light beam from the second laser. Thus, both light sources are configured such that emitted light from both sources travels in approximately the same direction.

(28) FIG. 7 shows operation of light source positioning. This shows the embodiment of FIG. 6, with the light sources moved in the direction of arrow 348 along the rail 326. In this way, the light sources can be moved with fine adjustment to identify the billiard ball pertaining to the winning lag. Note that while FIG. 7 shows movement of light sources using the embodiment of FIG. 6 having two light sources, embodiments having one light source, or more than two light sources, can operate in a similar manner using rail 326. Thus, embodiments include a rail disposed along a longitudinal axis of the enclosure, where the laser is configured to move along the rail.

(29) FIG. 8 shows details of a side view of a lag winner determination device 360 in accordance with yet another embodiment of the present invention. Device 360 is mostly similar to device 300 shown in FIG. 5, with a difference being a plurality of elongated supports (shown as 362 and 364) disposed on a bottom surface 366 of the enclosure 307.

(30) FIG. 9 shows details of a bottom-up view of the embodiment of FIG. 8. The bottom-up view shows an embodiment with four elongated supports, indicated as 362, 364, 368, and 370.

(31) FIG. 10 shows usage of the embodiment of FIG. 8. As shown in FIG. 10, the device 360 is supported on elongated supports (364 and 370 are visible in this figure). In embodiments, the height H2 of the elongated supports is greater than the height H1 of a billiard ball. Billiard balls can vary in height, but most are less than three inches in diameter. Thus, in some embodiments, the elongated supports have a height H2 ranging from 3 to 3.5 inches. In this way, should a measurement need to be taken while other billiard balls are on the table, the height is such that in most cases, the device 360 can be used without disturbing any billiard balls that are on the table at the time of use. Further, such an implementation may be used for training purposes such as, but not limited to, lining up a proposed shot.

(32) In embodiments that utilize elongated supports (legs), the light source 322 may be configured such that the light emitted is angled downward at an angle A from horizontal reference 329. In embodiments, angle A ranges from about 10 degrees to about 30 degrees. Additionally, light source 322 may be configured to emit a planar output of light 327 having an angle B. In embodiments, angle B ranges from about 10 degrees to about 30 degrees. In embodiments, the planar fan of light may be implemented by using a laser line lens on the front of light source 322. In some embodiments, a rotating mirror may be used as a line generator. Other laser line generation techniques may be used in embodiments of the present invention.

(33) FIG. 11 shows a schematic diagram of an embodiment of the present invention. A power source 374 is coupled to power switch 320. When power switch 320 is in an ON configuration, the light source 322 is activated to produce a beam or line of light used for determining a lag winner. In embodiments, the power source 374 is a battery. In embodiments, the power source 374 comprises a rechargeable battery. In embodiments, the rechargeable battery includes a nickel cadmium battery. In embodiments, the rechargeable battery includes a lithium ion battery. Other battery types may be used in some embodiments. In some embodiments, a wired power source (not shown) from an alternating current source (e.g. wall outlet) may be used.

(34) FIG. 12 shows details of a bottom-up view of yet another embodiment of the present invention. Device 380 is mostly similar to device 360 shown in FIGS. 8-10, with a difference being the use of three elongated supports (382, 388, and 390). Since three points define a plane, the embodiment of FIG. 12 is stable, while having a reduced contact area of table surface with the elongated supports.

(35) As can now be appreciated, disclosed embodiments provide techniques for determining the lag winner in a billiards game. This can be difficult to perform by human eye when the two players have a close lag. Disclosed embodiments utilize a light source such as a laser light source to identify which ball is closer to the head rail after the lag, and thus accurately determine a winner. In addition to determining a winner of a lag, the apparatus disclosed herein can have other billiards applications, such as use as a training tool for difficult and/or trick shots. This can be accomplished by aiming the light source at the desired point on a ball to determine an appropriate path for the shot.

(36) In yet another embodiment of the present invention, there may be an electronic system that interfaces with or works in conjunction with the lag winner determination device 300. For example, a user may utilize an application running on an electronic device (i.e. smart phone, smart watch, tablet, or other computing device). This application may receive data from the lag winner determination device 300 to create representations of the lag determination on a display screen associated with the electronic device. Overlays may appear on the display screen illustrating various measurements, lines, calculations, lag winners, etc. This information may be communicated to other electronic devices or otherwise communicated to those partaking in the gameplay and officiating/spectating such that a winner of the lag is clearly announced and determined.

(37) Further, an optical device, such as a camera, coupled to the electronic device may be able to capture a representation of the playing area after each player has lagged, or before or after each individual player has completed their lag. The representation captured by the electronic device can then be analyzed by the application to determine a lag winner. In such a scenario, the representation, be it a static or time varying image, is analyzed by a processor to determine objects located in the representation such that identification of the necessary locations (e.g. player 1 ball, player two ball, table rails, etc.) are appropriately identified allowing for a distance measuring algorithm to calculate the winner of the lag.

(38) When introducing elements of the present disclosure or the embodiment(s) thereof, the articles a, an, and the are intended to mean that there are one or more of the elements. Similarly, the adjective another, when used to introduce an element, is intended to mean one or more elements. The terms including and having are intended to be inclusive such that there may be additional elements other than the listed elements.

(39) Although the embodiments have been described with a certain degree of particularity, it is to be understood that the present disclosure has been made only by way of illustration and that numerous changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention.
