Abstract: A system and a method to wirelessly synchronize, monitor, or communicate, or a combination thereof, amongst sensors (e.g., sensors, hubs, sensor controllers, etc.) in a Bluetooth Low Energy-based microlocation system. The system or method, or both, may use the BLE hardware (e.g., transmitters, receivers, antennas, etc.) to interleave a communications protocol within the connection interval gaps of the BLE protocol used to communicate with devices.

Abstract: A coin acceptor for use in accepting coins, paper currency, tokens, or magnetic cards includes a multi-state visual display for indicating the condition of the coin acceptor or an attached device. The coin acceptor finds application in connection with gambling devices including video poker games and slot machines, as well as with vending machines, arcade games, automated teller machines, and other similarly actuated devices and machines. In a preferred embodiment, the coin acceptor finds application in connection with a progressive jackpot component for a live casino table game and includes a visual display having three different states. In a first state, corresponding to jackpot wager attract or invitation, a plurality of LEDs surrounding a token slot flash sequentially to form a traveling pattern around the slot. In a second state, corresponding to jackpot wager placement, the LEDs flash simultaneously. In a third state, corresponding to jackpot wager acceptance, the LEDs remain continuously illuminated.
