Patent granted for a security device with controllable usb connection
A recently granted patent (Publication Number: US11763641B2) describes a security device that can be connected to an electronic device via a Universal-Serial-Bus (USB) connector. The security device includes a controllable terminal connection structure that can physically connect or disconnect the USB connector from the electronic device. The device also features a measurement circuit to measure electrical properties associated with the USB connector. One or more processors are configured to control the terminal connection structure based on the measured electrical properties. The terminal connection structure includes a switch that can be switched between a connected state and a disconnected state. The switch can only be controlled by the processors, except for switching from the disconnected state to the connected state, which requires a manual input at a user interface of an additional controller. The security device also includes a lockable mechanical protection structure to restrict physical access to the user interface.
The patent also describes an application of the security device in an automated teller machine (ATM). In this application, the security device is connected to the electronic device inside the ATM via the USB connector. The security device is placed inside the safe unit of the ATM, while the USB connector is connected outside the safe unit. The electronic device controls the operation of an electromechanical device inside the safe unit based on control data transmitted via the USB connector. The ATM may also include a computing system connected to the USB connector or integrated into it.
The patent further discloses a method for operating an electronic device arrangement. The method involves connecting a first electronic device to a second electronic device via a USB interface, which includes an electrical connection structure and a switch to disconnect the connection. The method includes measuring electrical properties associated with the connection structure and triggering the switch to disconnect the connection based on the measured properties. After triggering the switch, the switch can be manually reset. The manual reset is performed through a manual input at a user interface of an additional controller independent from the processors. Before manually resetting the switch, a mechanical protection structure is unlocked to gain physical access to the user interface. The manual reset can also be achieved through a mechanical mechanism to reconnect the first and second electronic devices.
Overall, this patent describes a security device with a controllable terminal connection structure that can be used in various applications, including ATM machines, to enhance security and control the physical connection of USB devices.
