The compatibility module generates a compatibility signal indicating the input device is compatible with the input module or indicating that the input device is incompatible with the input module based on electronic information stored on the input device. The magnetic force module that generates a magnetic force between a connector of the input device and a receptacle of the input module based on the compatibility signal. ## Claims ### Claim 1 A control system for a coupling an input device and an input module of an imaging system for a medical procedure; comprising: a compatibility module that generates a compatibility signal indicating the input device is compatible with the input module or indicating that the input device is incompatible with the input module based on electronic information stored on the input device; a magnetic force module that generates an electromagnetic force between a connector of the input device and a receptacle of the input module based on the compatibility signal, wherein the magnetic force module applies a first attractive level of the electromagnetic force when the compatibility signal indicates compatible and a first repelling level of the electromagnetic force when the compatibility signal indicates incompatible; and an active procedure module that generates an active procedure signal indicating the medical procedure is active or indicating the medical procedure is no longer active based on at least one of a user input and image data generated by the input device, wherein the magnetic force module applies a second attractive level that is greater than the first attractive level when the active procedure signal indicates active. ### Claim 2 (depends on 1) The control system of claim 1, further comprising: a connection monitor that generates a connection signal indicating the connector and the receptacle are in a connected state or the connector and the receptacle are in a disconnected state, wherein the magnetic force module applies the first attractive level when the connection signal indicates the disconnected state and the active procedure module indicates active, and wherein the magnetic force module continues to apply the second attractive level when the connection signal indicates the connected state and the active procedure module indicates active. ### Claim 3 (depends on 2) The control system of claim 2, further comprising: a timing module that increments a timer when the connection signal indicates the disconnected state and the active procedure module indicates active, wherein the magnetic force module continues to apply the first attractive level while the timer is less than a predetermined threshold and the connection signal indicates the disconnected state, wherein the magnetic force module increases from the first attractive level to the second attractive level while the timer is less than the predetermined threshold and the connection signal indicates the connected state. ### Claim 4 (depends on 1) The control system of claim 1, wherein the compatibility module includes an RFID reader chip and the electronic information is stored on an RFID tag chip of the connector such that the RFID reader chip powers the RFID tag chip using radio wave energy to transmit electronic information. ### Claim 5 (depends on 1) The control system of claim 1, wherein the input device is one of a video camera for an endoscope and a video endoscope. ### Claim 6 A coupling system for coupling an input device and an input module of a medical imaging system, comprising: a connector at a terminal end of a cable of the input device that includes one or more connector magnets and an RFID tag chip, the connector terminating in a planar surface without exposed terminals; a receptacle within the input module that includes one or more receptacle magnets and an RFID reader chip, the receptacle terminating in a planar surface without exposed terminals; and a control system including a compatibility module that generates a compatibility signal indicating the input device is compatible with the input module or indicating that the input device is incompatible with the input module based on electronic information stored on the RFID tag chip; and a magnetic force module that generates an electromagnetic force in the one or more receptacle magnets based on the compatibility signal, wherein the magnetic force module applies a first attractive level of the electromagnetic force when the compatibility signal indicates compatible and a first repelling level of the electromagnetic force when the compatibility signal indicates incompatible; and an active procedure module that generates an active procedure signal indicating the medical procedure is active or indicating the medical procedure is no longer active based at least one of a user input and on image data generated by the input device, wherein the magnetic force module applies a second attractive level that is greater than the first attractive level when the active procedure signal indicates active. ### Claim 7 (depends on 6) The coupling system of claim 6, further comprising: a connection monitor that generates a connection signal indicating the connector and the receptacle are in a connected state or the connector and the receptacle are in a disconnected state, wherein the magnetic force module applies the first attractive level when the connection signal indicates the disconnected state and the active procedure module indicates active, and wherein the magnetic force module continues to apply the second attractive level when the connection signal indicates the connected state and the active procedure module indicates active. ### Claim 8 (depends on 7) The coupling system of claim 7, further comprising: a timing module that increments a timer when the connection signal indicates the disconnected state and the active procedure module indicates active, wherein the magnetic force module continues to apply the first attractive level while the timer is less than a predetermined threshold and the connection signal indicates the disconnected state, wherein the magnetic force module increases from the first attractive level to the second attractive level while the timer is less than the predetermined threshold and the connection signal indicates the connected state. ### Claim 9 (depends on 6) The coupling system of claim 6, wherein the input device is one of a video camera for an endoscope and a video endoscope.
