Abstract: A smart control module for a coin-operated device includes a control board disposed with a processing unit, a back-end port, and a communication unit that are electrically connected to the processing unit. A front-end port is disposed on the control board and is adapted to receive a coin insertion signal outputted by a coin acceptor. The back-end port outputs the coin insertion signal in a bypassing way. When the communication unit receives a control signal from a service platform, the processing unit outputs a simulated coin insertion signal through the back-end port. Upon using the present invention, the front-end port and the back-end port are connected between the coin acceptor and a controller of the coin-operated device. The service platform could remotely control the back-end port to output the simulated coin insertion signal to the controller after receiving a malfunction reported by a user.

Abstract: A warehouse system includes N carriers, N gravity sensor sets, a scale device, and a computer device. Each carrier is used for disposing at least one load. Each gravity sensor set is disposed below each carrier for detecting a loading weight of each carrier. The scale device is disposed below the N carriers and the N gravity sensor sets for detecting a total weight of the N carriers, the N gravity sensor sets, and all loads. The computer device is coupled to the N gravity sensor sets and the scale device for generating load quantity variations by using the N gravity sensor sets and the scale device.
