DETAILED DESCRIPTION
(8) With reference initially to
(9) The apparatus 10 includes a housing assembly 20, which holds or otherwise supports other parts or components of the apparatus 10. The housing assembly 20 includes a card receiver subassembly 24, which includes a card receiver body 28 having an upper surface 32. The upper surface 32 can be even with, or at least substantially aligned with, a casino game layout or table covering felt material 36, as depicted in
(10) The card receiver subassembly 24 also includes a transparent lens protector 60 that can be located within the card receiver body 28 and held thereby by any suitable means, such as by a snap in or friction fit. The lens protector 60 can be made of glass or acrylic and can prevent unwanted dust or other particles from passing through the opening 48 and possibly contacting and/or obstructing a lens 64 of a camera assembly 68, with the camera assembly 68 including lens 64 being seen in
(11) Continuing to refer to
(12) The housing assembly 20 can include a foam member 88 that can surround the card receiver body 28. The foam member 88 has an opening 92 having portions that can be aligned in a vertical direction with the card receiving body opening 48 and with the lens protector 60. The foam member 88 can be useful in locating the apparatus 10 relative to a cut-out 96 formed in the wood structure 100 of a casino table during installation when the apparatus 10 is joined to a casino table. The foam member 88 can be made of a material similar to, or having physical characteristics like, the foam layer 104 of

The mount plate 112 can be joined to the card receiver body 28 of the card receiver subassembly 24 using the fasteners 72a, 72b. The mount plate 112 can be connected to the casino table wood structure 100 of the conventional casino table using a number of connectors 124, such as wood screws.
(14) The housing assembly 20 can possibly include, as also illustrated in
(15) The housing assembly 20 can also possibly include, as further illustrated in
(16) From such descriptions regarding possible use of one or more reader shims 136 or one or more foam shims 140, it should be understood that, if a reader shim 136 is used, a foam shim 140 would be unnecessary and not be used. Similarly, if a foam shim 140 is used, a reader shim 136 would not be necessary and would not be used.
(17) With reference primarily to
(18) An illuminator device 182 is positioned within the space 162, preferably fixed in position near the top of the wall 166 and above the lens 64 of the camera assembly 68. The illuminator device 182 is powered to output light of a desired intensity to ensure proper operation of the camera assembly 68 by providing adequate lighting. The camera assembly 68 also includes a camera body 186 and a camera board 190 with electronic hardware or components useful in outputting the image data that is obtained by the camera assembly 68. The image data can include such data associated with the symbol or card rank provided on a particular down card currently being read. The camera assembly, in one embodiment, can be Model ELP-USB130W01MT-B/W-L21 available from Ailipu Technology Co., Ltd.
(19) The apparatus 10 also includes a computer board 196 that includes a computer 200. As shown by
(20) With further reference to
(21) Referring also to
(22) This advantageous configuration for supporting or holding in place key or substantial portions of the apparatus 10, as well as possible removal thereof from a casino table, is further enhanced by use of the hooks 174 formed in the walls 166, 170 of the housing sections 146, 150 and the notches 178 formed in the mount plate 112. After the mount plate 112 is attached to the wood structure 100, and with the elongated fasteners 72a, 72b extending therefrom, the first and second housing sections 146, 150, which are joined together using the bracket subassembly 244, can be moved upwardly from below the casino table wood structure 100. During such movement, the fasteners 72a, 72b are inserted in the ears 256 of the ring member 248. Such movement or placement continues with the hooks 174 ultimately being in a position to be received by the notches 178. Movement completion and desired positioning are achieved by the mating engagement between such hooks 174 and notches 178. With such engagement in place, the finger-tightened nuts 84a, 84b can be joined to their respective fasteners 72a, 72b beneath the ears 256 to secure the already joined first and second housing sections 146, 150, together with the parts or components held therein, to the casino table.
(23) As illustrated in
(24) With reference to
(25) As indicated by block 310 of
(26) After the boundaries of the card-identifying portions are found, wherein it is known that the card rank or symbol can be identified using the pixel-based information within such boundaries, the computer 200 generates an array that has such pixel-based information, as indicated in block 334. The array can include substantially equal area squares obtainable using the defined rectangle. In one embodiment, the equal area squares can be twelve in a first (vertical) direction and seven in a second (lateral) direction so that there are a total of eighty-four equal squares. The computer 200 processes each of these elements of the array by finding the proportion of black pixels to white pixels in each array element. The results of the processing has each array element associated with a value in the range between zero (full white/blank) and one (full black/sufficiently dark), inclusively.
(27) Referring next to block 338, the array including array elements can then be used by or input to a neural network executed by the computer 200, with the array elements essentially being the inputs to the neural network. In one embodiment, the neural network can be a multilayer perceptron, a commonly used neural network, which can have a hidden layer associated with a suitable or desirable number of neurons. The number of neurons can be selected based on training the neural network (e.g. sixty neurons). Such training can utilize a standard backpropagation technique or method. According to one embodiment, based on the processing done by the neural network, thirteen numbers or values can result, with each of these numbers/values being associated with one of the thirteen playing card ranks or values, as indicated by block 342. These thirteen numbers can be in the range of +1 to 1, inclusively. A match to one of the thirteen card ranks can be indicated by a number close to +1. A non-match can be indicated by a number close to 1. In another embodiment, instead of thirteen numbers, only three numbers are utilized based on the three categories/groups (small, medium and large) required to play the Down Under Blackjack game. In yet another embodiment, fifteen numbers are utilized to take into account differences/additions to playing cards that may be used in certain jurisdictions. That is, the letter B may be found on cards instead of the ten through king symbols and no peek indicia may be found on cards having an ace rank.
(28) In conjunction with the outputs from the neural network and referring to block 346, the computer 200 and the thirteen numbers associated with card ranks are used to identify the actual or specific rank of the down card whose card portions are currently in the slot 44. In that regard, first computer software can be executed by the computer 200 that processes at least two of the thirteen numbers in order to achieve substantial certainty related to the identity of the down card rank. Such software can obtain the difference between a match value (close to +1) and the closest non-match value (1). For a perfect match, the difference would be +2. In one embodiment, a difference of less than 1.99 can be rejected as having inadequate confidence of a match and so no rank would be identified. Based on such a difference, the down card can be identified. However, the Down Under Blackjack game requires that the down card be grouped or classified into one of three groups or sets, and not that the specific down card rank be provided to any player or dealer.
(29) Consequently, according to block 350, information or data related to the identity of the down card rank is further processed by inputting or using such identity related information to group or classify the down card into the small, medium and large card sets previously described. To do that, an algorithm, implemented using second or classifying associated software executed by the computer 200, can be utilized. Generally, this algorithm determines the one of the three predetermined card sets associated with the currently read or used down card. Such determination can be done by matching the identified down card rank with a card rank that is a member of, or included with, one of the three predetermined sets. Matching could be accomplished by comparing the down card rank with each card rank of each predetermined set until a match is found, while tracking which predetermined set is being used during the compare. Regardless of the particular process employed, once a match is found, an output indicative of the determined one of the three sets can be output by the computer 200, as conveyed by block 354.
(30) Next at block 358, the computer output associated with the classified down card rank (small, medium or large) is utilized to activate the corresponding color indicator 56. Such activation can be done by using this computer output to ultimately control power applied to the color indicator 56 corresponding to the classified down card rank.
(31) Referring to
(32) In addition to the activation of the indicator 56 corresponding to the set of the down card rank, the dealer moves the down card with the dealer's up card on top thereof from the apparatus 10 to a corresponding classifying area on the game layout 36, as indicated by block 362. The game layout 36 includes three classifying areas 366a, 366b, 366c. Each one of the three areas 366 is identified to show the correspondence. One of the three classifying areas 366 can be labeled/identified as small (366a). Another one of these three areas can be labeled as medium (366b). The remaining area can be labeled as large (366c). Additionally or alternatively, the identifying information on the layout related to card rank sets can include the individual and specific ranks associated with each of the three classifying areas. That is, the small set can also have the ranks 2, 3, 4, 5 printed on or associated with that classifying area. Likewise, the card ranks for cards in the medium and large sets can be provided with their respective classifying areas. In continuing with the example of the current down card being identified as 8 and being classified in the medium set, after seeing the color indicator 56b being on or lit, the dealer recognizes that this indicator 56b, with a particular color different than the colors of the other two indicators 56a, 56c, is associated with the medium set and positions the down card with aligned up card in the layout classifying area 366b associated with the medium set.
