摘要:
An image capture system for recording X-ray images in real time is disclosed. The image capture system includes an image pickup device, a sensing module and a surgical navigation device. The sensing module is used to detect the on/off status of the image pickup device. While the image pickup device is turned on to capture an X-ray image, the sensing module transmits a notification signal to the surgical navigation device. After receiving the notification signal, the surgical navigation device records the X-ray image captured by the image pickup device and the relative position between the image pickup device and the patient in real time. Thus, the real-time recording of the relative position between the image pickup device and the patient will prevent inaccurate image reading that occurs when the patient's position and image pickup device shift after the X-ray image has been captured.

A backup power system with a fuel cell and a control method thereof are provided. The control method includes the steps of: setting a default variation value; determining whether power interruption has happened to a grid power module; determining whether a load is functioning; performing a limiting step; and controlling the output of a fuel cell system. With the control method, the fuel cell system functions as a backup power system configured for grid power, and the fuel cell system generates power in response to variation of the load.

A system of a plurality of series-connected fuel cell converter devices and a method for controlling the system are provided. The system includes a plurality of fuel cell converter devices, a series connection unit, a power control unit, a Mux control unit, and a master controller. The output ends of a plurality of fuel cell converter devices are connected in series by the series connection unit. The master controller reads signals from the power control unit and the Mux control unit and determines accordingly which fuel cell converter devices need to be turned on to meet the requirement of a load. The method includes the steps of estimating a load, determining the number of the fuel cell converter devices to be turned on, calculating an output power, discharging, and charging. Thus, a plurality of fuel cell converter devices is controlled to output the required power of the load.

A system of a plurality of parallel-connected fuel cell converter devices and a method for controlling the system are provided. The system includes a plurality of fuel cell converter devices, a parallel connection unit, a power control unit, a Mux control unit, and a master controller. The output ends of the plurality of fuel cell converter devices are connected in parallel by the parallel connection unit. The master controller reads signals from the power control unit and the Mux control unit and determines accordingly which fuel cell converter devices need to be turned on to meet the requirement of a load. The method includes the steps of estimating a load, determining the number of the fuel cell converter devices to be turned on, calculating an output power, discharging, and charging. Thus, the plurality of fuel cell converter devices is controlled to output the required power of the load.

The present invention discloses a system for recycling thermal energy generated from a fuel cell module. The system includes the fuel cell module, a thermal module, a heat-recycle module, and a control module. The thermal module includes a heat transfer apparatus. In addition, the thermal module connects with the fuel cell module, and the heat-recycle module connects with the heat transfer apparatus. The control module detects a starting signal of the fuel cell module and controls the thermal module and the heat-recycle module. Thereby, the thermal energy generated from the fuel cell module is transferred to the heat-recycle module.

A spine fixation device is provided. The spine fixation device includes a bone screw, a fixation carrier, and a first locking member. The fixation carrier is rotatably coupled to a fixation unit of the bone screw. The first locking member conjugates the fixation carrier and the bone screw together. A screw unit of the bone screw is implanted into a vertebra. As the fixation carrier is rotatably coupled to the bone screw, the bone screw remains fastened to the vertebra while the fixation carrier is rotated. Through rotational adjustment of the fixation carrier, U-shaped openings of the fixation carrier are adjustable in direction. Thus, the disposition angle of a rod disposed in the U-shaped openings is easily adjustable by rotating the fixation carrier. As a result, the rod can fit an angle of the spine while surgical complexity is reduced.

The present invention discloses a random controlled fuel cell power module. The random controlled fuel cell power module includes a power module system, a current detection unit, and a random control unit. The power module system is composed of at least two parallel-connected DC/DC converters, for providing the power for a load. The current detection unit detects a load current value of the load. The random control unit reads the load current value and randomly assigns a control mode to activate the DC/DC converters according to the load current value, so that the DC/DC converters can be equally used. Therefore, the failure rate of the DC/DC converters is reduced, the life of the power module system is relatively prolonged, and the stability of the power module system is simultaneously increased.

The present invention discloses an image calibration device integrated with an optical locater. The image calibration device includes an image calibrator and the optical locater. The image calibrator can be arranged on an image capturing device to act as a reference to calibrate the image taken by the image capturing device. The optical locater has at least one pointing light source, which is located on a surface of the image calibrator, so that the pointing light source is used to assist in marking the location aimed by the image calibrator, thereby realizing the area captured by the image capturing device.

A surgical guide instrument capable of omni-directional positioning and an omni-directional positioning unit thereof are provided. The surgical guide instrument includes the omni-directional positioning unit, which is coupled with the surgical instrument. The omni-directional positioning unit is configured as a pyramid, and a plurality of reflectors is deposited on vertices of the pyramid, respectively. As the reflectors of the omni-directional positioning unit are arranged as a three-dimensional pyramid, the omni-directional positioning unit can be connected in any position to the surgical instrument and be detected correctly by a surgical guide system, thereby reducing surgical complexity.
