Panorama image capturing device having at least two camera lenses and panorama image capturing module thereof

The present invention provides a panorama image capturing device and a panorama image capturing module thereof. The panorama image capturing module includes a lens structure, an optical structure, a single image sensing chip, and a single image signal processor. ... Prolific Technology Inc

Non-contact intelligent battery sensing system and method

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. ... Prolific Technology Inc

Image processing method for immediately producing panoramic images

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. ... Prolific Technology Inc

Method and device capable of automatically identifying host operating systems

The present invention provides a method and a device capable of automatically identifying host operating system. For the conventionally-used usb devices or usb bridge interfaces cannot effectively identify all kinds of operation systems (os) from an electronic device, the present invention proposes a novel usb device consisting of: a usb physical interface, a central processing unit, and at least one peripheral interface controller; wherein the central processing unit is particularly embedded with an os identifying library. ... Prolific Technology Inc
