The system and device includes a sterilizing lid that can be positioned over a complementary tray having modular roller inserts inserted, the modular roller inserts operating in concert with the sterilizing lid to rotate the gaming tokens while the sterilizing lid emits a sterilizing light. ## Claims ### Claim 1 A system for sterilizing a plurality of cylindrical gaming tokens positioned in parallel rows within one or more corresponding apertures within a gaming token tray, the system comprising: a gaming token tray lid housing including a sterilizing light emitter, which when activated, causes a sterilizing light to be emitted within the housing, the gaming token tray lid housing including an electrical contact that completes an electrical circuit when the gaming token tray lid housing is positioned on a corresponding gaming token tray; the gaming token tray having the one or more corresponding apertures, each aperture configured to receive a row of cylindrical gaming tokens of the plurality of cylindrical gaming tokens, the gaming token tray comprising: a plurality of modular roller devices, each modular roller device of the plurality of modular roller devices configured to be positioned between two adjacent parallel rows of cylindrical gaming tokens or an adjacent parallel row of cylindrical gaming tokens and a sidewall of the gaming token tray, each modular roller device comprising: one or more rollers adapted to be in physical contact with adjacent cylindrical gaming tokens in the adjacent parallel row or rows such that the one or more rollers, when rotated, cause the adjacent cylindrical gaming tokens to rotate through frictional engagement; one or more actuators coupled to a corresponding roller or corresponding rollers of the one or more rollers, which when electrically activated, cause the corresponding roller or corresponding rollers to rotate; and a controller circuit having at least one computer processor and coupled to the one or more actuators that cause rotation of the one or more rollers of the modular roller device for a duration of time such that the cylindrical gaming tokens are also rotated for the duration of time wherein the controller circuit includes one or more load sensor circuits configured to generate load data based at least on a corresponding rotation speed of each of the one or more rollers and a corresponding amount of power or energy provided to the one or more actuators, the load data provided to a central computer server coupled to each of the plurality of modular roller devices. ### Claim 2 (depends on 1) The system of claim 1, wherein the central computer server is configured to monitor the load data and to generate an alert when the load data corresponding to a modular roller device of the plurality of modular roller devices indicates an abnormal operating condition. ### Claim 3 (depends on 2) The system of claim 2, wherein the each of the one or more corresponding apertures within the gaming token tray includes one or more object detection sensors configured for tracking a load level corresponding to the corresponding aperture, and the abnormal operating condition is determined based on the load level of the adjacent row or the adjacent rows of the modular roller device corresponding to the load sensor. ### Claim 4 (depends on 1) The system of claim 1, wherein the controller circuit is configured to, upon detecting completion of the electrical circuit when the gaming token tray lid is positioned on the gaming token tray, control the one or more actuators to actuate for the duration of time. ### Claim 5 (depends on 4) The system of claim 4, wherein the electrical circuit is completed through electrical coupling of two sets of corresponding two or more power pins residing on the gaming token tray lid or the gaming token tray, respectively. ### Claim 6 (depends on 1) The system of claim 1, wherein the gaming token tray lid housing includes a timing circuit configured to control the duration of time in which the sterilizing light emitter is activated. ### Claim 7 (depends on 6) The system of claim 6, wherein the timing circuit is coupled to at least one controller circuit of at least one modular roller device and configured to modify the duration of time based on the load data received from the at least one modular roller device. ### Claim 8 (depends on 1) The system of claim 1, wherein the one or more corresponding apertures have an elliptical profile such that the cylindrical gaming tokens positioned within the one or more corresponding apertures are biased towards a bottom of the one or more corresponding apertures to increase a frictional engagement between the one or more rollers and the cylindrical gaming tokens. ### Claim 9 (depends on 1) The system of claim 1, wherein the plurality of modular roller devices are configured as removable modular inserts that are inserted into corresponding channels in the gaming token tray and electrically coupled to a power source residing within or proximate to the gaming token tray. ### Claim 10 (depends on 1) The system of claim 1, wherein the controller circuit is further configured to receive token presence data from a plurality token detection modules, each token detection module comprising a plurality of photoemitter/photoreceptors pairs configured for determining a presence of a corresponding cylindrical gaming token disposed within a corresponding location in the aperture. ### Claim 11 (depends on 10) The system of claim 10, wherein the token presence data is utilized by the controller circuit to determine an expected load value associated with operation of the one or more rollers. ### Claim 12 (depends on 10) The system of claim 10, wherein the token presence data is utilized by the controller circuit to maintain, in a data structure, one or more data objects representing whether tokens residing in one or more physical zones within the one or more apertures have been interacted with since a last sterilization cycle. ### Claim 13 (depends on 12) The system of claim 12, wherein each of the one or more physical zones is associated with a minimum sterilization duration based at least on a distance from the sterilizing light emitter during operation of a sterilization cycle, and the controller circuit sets the duration of time for operating the one or more rollers based on a maximum of the minimum sterilization durations for all zones of the one or more physical zones that have been interacted with since the last sterilization cycle. ### Claim 14 (depends on 13) The system of claim 13, wherein the distance from the sterilizing light emitter is based at least on a vertical distance arising from a slope in positioning of the one or more apertures. ### Claim 15 (depends on 10) The system of claim 10, wherein each modular roller device further comprises the plurality of photoemitter/photoreceptors pairs configured operating in conjunction with the one or more rollers. ### Claim 16 (depends on 10) The system of claim 10, wherein each modular roller device is disposed to alternate with a plurality of token detection modules.
