Abstract: An electric motor includes a motor main body and an inverter. The inverter is axially stacked on one end of the motor main body, and the inverter includes a gate driver, a control circuit, a capacitor module, a DC bus bar, a plurality of power modules and a plurality of AC bus bars. The power module includes a plurality of AC output terminals, a plurality of DC input terminals and a plurality of signal terminals, and the AC bus bars are respectively connected to corresponding AC output terminals and extend downward to a motor coil of the motor main body. The power modules and the corresponding DC input terminals are annularly arranged around the capacitor module, the DC bus bar is extended and electrically connected to the corresponding DC input terminals and the capacitor module.

Abstract: A method for controlling the IoT devices and an IoT system using the same are provided. The IoT devices includes a trigger device and a functional device. A managing software is executable on a client device. First, a credential is sent to the client from the functional device. Second, a script is received at the trigger device. The script includes the credential, at least one supported command, and at least one supported event. The script is generated at the managing software. The supported command is recognizable to the functional device. When the supported event is triggered at the trigger device, the supported command from the trigger device is received at the functional device. Then, a function of the functional device is performed based on the command, which increases the convenience of operating the system. The trigger device need not recognize the command, which increases the flexibility of the system.

Abstract: The present invention provides a tissue treatment tool and signal processing method of the same. The present invention is capable of processing a vibrating signal generated according to a feedback from the soft/hard tissue contacted by the tissue treatment tool during the treatment process so as to obtain an electrical processing signal with respect to a feedback vibration status with respect to soft/hard tissue. According to the electrical processing signal, it is capable of determining the location of the tissue treatment tool or the tissue thickness while treating the target tissue, thereby generating a display signal for displaying the location on a display unit or issuing a stopping signal for stopping providing power to the tissue treatment tool automatically in response to thickness status so as to prevent the soft tissue around the treated tissue from being damaged.

Abstract: An FIR-based apparatus performs fast convolution in the frequency domain for generating room reverberation. The impulse response of a room is segmented and transformed by FFT to form a plurality of segmented room frequency spectra. The input signal to the room is also segmented and transformed to form segmented input frequency spectra. Either overlap-and-add method or overlap-and-save method is applied in the apparatus to accomplish the fast convolution based on the multiplication of segmented input frequency spectrum and segmented room frequency spectrum. To further reduce the complexity of the convolution, a segmented room frequency spectrum is processed to remove high frequency components before being used in the fast convolution according to a perceptual criterion.
