An alarming method for a ventilator and a ventilator alarm system are provided. The method includes the following. First, a plurality of ventilation parameters are received and detected. If a peak airway pressure of the ventilation parameters conforms to a first condition, whether a plateau pressure conforms to a second condition is determined, wherein the first condition is Y&#x3e;Y+3*Y, and the second condition is Y&#x3c;Y+3*Y. If the plateau pressure does not conform to the second condition, an airway static obstruction alarm is activated. If the plateau pressure conforms to the second condition and a third condition, an airway dynamic obstruction alarm is activated.

A visual drive control method with multi-phase encoding includes the following steps. A plurality of flickering sequences are generated by an encoding process according to a reference phase and a plurality of shifting phases divided in time division under at least one phase shift state, then a display unit is driven to display corresponding optical images. An optic nerve of an organism is evoked by the optical images, such that the organism generates a corresponding biological signal. Next, a computation process is performed to a digital biological signal converted from the biological signal to acquire an average captured reference phase and an average captured shifting phase of the digital biological signal. Then, the frequencies and the phase states of the digital biological signal and the flickering sequences are compared to output a corresponding control signal. A visual drive control apparatus with multi-phase encoding is disclosed herein.

A control method of a brain computer interface (BCI) with a stepping delay flickering sequence is provided. First, a plurality of different flickering sequence signals are generated by encoding a static flashing segment and a plurality of stepping delay flashing segments divided in different time sequences. Then, a plurality of target images corresponding to the flickering sequence signals are displayed. Thereafter, a response signal generated by an organism evoked by the target images is acquired. Then, signal processing is performed on the response signal by using a mathematic method to distinguish which one of the target images is gazed by the organism. Thereafter, a controlling command corresponding to one of the target images is generated. A control system of a BCI with a stepping delay flickering sequence is also provided herein.

A power-diode driver uses a single power source to supply power to the sub-drivers inside. The sub-drivers are well isolated so that they can be safely and easily expanded by connecting to other device or driver. Thus, the power-diode driver has a changeable turn-on time and a highly modulated assembly. And, hence, the present invention is suitable for mass producing reliable power-diode drivers.

A non-contact power system transfers power and signals simultaneously. The signals control the non-contact power system. And an operational frequency is operated on a resonant frequency so that there is no voltage alternating on power switch and power loss is reduced.
