Abstract: A calibration device for a computer-assisted surgical instrument includes a rigid body, stabilization members, and references structurally or mechanically complementary to the stabilization members and disposed on opposite sides of a manipulator of the instrument. Kinematic state of the manipulator is defaulted when the calibration device is connected to the instrument by the stabilization members passing through the rigid body and removably attaching to the references. A calibration method for a computer-assisted surgical instrument implemented by a computer system includes the steps of: prompting a user to connect the calibration device to the instrument; determining if the calibration device is properly connected to the instrument; and generating default kinematic information of the manipulator of the instrument if the calibration device is properly connected to the instrument. The calibration device and method effectively improve accuracy and precision of computer-assisted surgeries.

Abstract: A mapping table management method for a solid state storage device is provided. The solid state storage device includes a control circuit, a dynamic random access memory and a non-volatile memory. The mapping table management method includes the following steps. When the control circuit receives a write command, the control circuit stores a write data into the non-volatile memory and updates a mapping table in the dynamic random access memory. If the control circuit receives a power-off command, the control circuit stores an entire of the mapping table from the dynamic random access memory to the non-volatile memory. If the control circuit judges that an update condition is satisfied, the control circuit stores a portion of the mapping table from the dynamic random access memory to the non-volatile memory.
