Abstract: A USB hub includes an upstream port; a first USB device control unit for performing packet format conversion; an FIFO circuit for storing data outputted from the first host; a second USB device control unit for performing packet format conversion; and a plurality of downstream ports. When any one of the downstream ports is coupled to the mobile device, if the first host commands the mobile device to switch to a host role from a device role, the mobile device temporarily disconnects from the USB hub, and the first host commands the USB hub to change an internal routing path. After the mobile device switches to the host role, the first host still performs the host role, and the first USB device control unit performs the device role; the mobile device performs the host role, and the second USB device control unit performs the device role.

Abstract: An electromagnetic impedance sensing device includes a first substrate, a first patterned conductive layer, a second substrate, a second patterned conductive layer, a magneto-conductive wire and an encapsulation layer. The first substrate has a first surface, and the first patterned conductive layer is formed on the first surface. The second substrate has a second surface facing to the first surface, and the second patterned conductive layer is formed on the second surface and electrically contacted to the first patterned conductive layer. The first and second patterned conductive layers are physically integrated to define an accommodation space allowing the magneto-conductive wire passing there through. The magneto-conductive wire is encapsulated by the encapsulation layer to make the magneto-conductive wire electrically isolated from the first and second patterned conductive layers, respectively. At least one coil circuit surrounding the magneto-conductive wire is formed by the first and second patterned conductive layers.

Abstract: 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.

Abstract: The present invention provides an image processing method for immediately producing panoramic images. In this method, two fish-eye cameras are used for capturing video information, and then, a streaming video is transmitted to an electronic device by wired or wireless technology after the video information is treated with a video encoding process and a streaming process. Therefore, an image processing application program installed in the electronic device is able to subsequently treat the streaming video with a video encoding process, a panoramic coordinates converting process, an image stitching process, and an edge-preserving smoothing process in turns, so as to eventually show a sphere panorama on the display of the electronic device. Moreover, by the utilization of a digital signal processor, the image processing application program is able to further process the sphere panorama to a plain panorama, a fisheye panorama, or a human-eye panorama.

Abstract: An impedance sensor and an electronic apparatus using the same are provided. The impedance sensor includes an impedance-bridge circuit, a compensation circuit, and a signal processing circuit. The impedance-bridge circuit has an input side and an output side, and configured to generate a first impedance variation in response to a physical pressure. The compensation circuit is coupled to the input side of the impedance-bridge circuit in parallel, and configured to generate a second impedance variation in response to an environment temperature. The signal processing circuit respectively detects the first and the second impedance variations, and accordingly generates a first sensing signal indicating the first impedance variation and a second sensing signal indicating the second impedance variation, so as to compensate a temperature shift part of the first sensing signal by the second sensing signal and accordingly generate a pressure detection signal.

Abstract: A negative voltage protection system includes a negative voltage comparison circuit, a signal processing circuit, a driving circuit, a driving output circuit, a power device, and a coil module. When the coil module generates a back electromotive force, the coil module outputs a negative voltage. When an intensity of the negative voltage detected by the negative voltage comparison circuit is greater than a predetermined value, the signal processing circuit generates a control signal to the driving circuit. The driving circuit controls the driving output circuit and the power device to reduce the intensity of the negative voltage according to the control signal.
