A system includes at least one sensor and at least one controller. The at least one sensor is configured to generate a first weight signal corresponding to a first weight of a first lot of substrates, and a second weight signal corresponding to a second weight of a second lot of substrates. The at least one controller is coupled to the at least one sensor to receive the first weight signal and the second weight signal. The at least one controller is configured to convert a weight difference between the first weight and the second weight into a number of substrates each having a predetermined weight. The at least one controller is further configured to, based on the converted number of substrates, control a processing apparatus to rotate the first lot of substrates and the second lot of substrates simultaneously.

An inspection system of a chip includes a reading device and a determining unit. The reading device is configured to count a number of chips stored in a storage case, the chips associated with a table game and including a chip having a radio tag, read the radio tag while the chips are stored in the storage case, and acquire chip information. The determining unit is configured to compare the chip information of the chips in the storage case with a physical number of the chips in the storage case, determine that there is an abnormal chips among the chips stored in the storage case based on a determination that the counted number of the chips does not match a physical number of the chips in the storage case, and output a result associated with an indication of the abnormal chip.

A system for signaling an overload of a foam mattress, including a foam mattress having a plurality of conductive inserts located near a bottom surface and a contact pad positioned below the bottom surface of the mattress. The system may generate an overload alarm signal as a function of receiving one or more signal outputs from the sensor over a period of time. The system may also generate an overload alarm signal as a function of receiving a plurality of individual signal outputs from a plurality of one or more conductive inserts located within a predetermined area of the sensor.

A tower stores unmanned aircraft and shipping containers inside. The unmanned aircraft are controlled by the tower's integrated computer to enable immediate distribution of the shipping containers upon a customer request. Upon a customer request, the tower autonomously dispatches the unmanned aircraft stored inside to rapidly fly out of the tower to deliver a shipping container directly to a specified location outside. Once dispatched by the tower's computer system, the unmanned aircraft autonomously fly from storage in the tower through the tower's interior space and exit the tower through internal shafts that lead to an opening in its exterior walls to deliver a shipping container cheaper and faster than traditional means.

A game token management system includes; a game token tray (17) for storing game tokens of a dealer; a card distribution device (3) that determines a result of a game; a management control device (50) that determines a target and an amount bet by a player and an amount of the game tokens held in the game token tray (17) and determines whether a change of the game tokens in the game token tray (17) after an end of the game is accurate or inaccurate; and an indicator lamp (173) that is turned on or off according to determination of the management control device (50).
