摘要： Disclosures of the present invention describe a switch device has a controlling and processing unit comprising a first zero point detector, a second zero point detector, an arc detector, and a microcontroller. According to zero crossing point of input voltage signal, zero crossing point of output voltage signal, relay's delay time, and arc-spark-induced signal, the microcontroller is capable of adaptively generating a relay controlling signal to control the relay, such that the relay achieves a short-circuit switching at the zero cross point of output voltage signal for making the output voltage signal be transmitted to at least one load device. Moreover, the microcontroller is also able to control the relay to finish a short-circuit switching at the zero cross point of input voltage signal, so as to stop the output voltage signal from being transmitted to the load device.

摘要： In view of drivers cannot equip their vehicles with conventional intelligent battery monitoring system by themselves because the wire connections of the intelligent battery monitoring system are complex, the present invention particularly discloses a non-contact intelligent battery sensing system showing the advantages of simple circuit framework and low manufacturing cost. Since the non-contact intelligent battery sensing system only comprises a magnetic field sensor and a sensor controlling module, it is very easy for the drivers to equip their vehicles with this non-contact intelligent battery sensing system by themselves. To apply the non-contact intelligent battery sensing system, the driver just needs to firstly dispose the magnetic field sensor at one position near to a power line of a battery to be sensed, and then install a sensor controlling application program in his smart phones. Apparently, the non-contact intelligent battery sensing system further shows the advantage of easy to be installed.

摘要： A storage device with automatic-switching function is disclosed. When the storage device is coupled to a USB interface, the power provided by the USB interface turns the USB/SATA converter on to convert data from the USB interface into SATA format and transmit to a hard disk. When the storage device is coupled to a SATA interface instead of the USB interface, the power provided by the USB interface does not turn the USB/SATA converter on to convert data. In this way, the data from the SATA interface directly transmit to the hard disk.
