    摘要： Systems, devices, media, and methods are presented for generating texture models for objects within a video stream. The systems and methods access a set of images as the set of images are being captured at a computing device. The systems and methods determine, within a portion of the set of images, an area of interest containing an eye and extract an iris area from the area of interest. The systems and methods segment a sclera area within the area of interest and generate a texture for the eye based on the iris area and the sclera area.

    摘要： An electrical impedance detecting device of a portable electrical impedance imaging system by utilizing a theory of sending excitation signal and detecting response signal and a method thereof, wherein the excitation signal is a constant square wave excitation current signal, the response voltage signal on a target is transformed to a square wave signal with appropriate amplitudes by buffering, amplifying, RC filtering and differential amplifying circuits, and then is transformed to a digital signal at a proper time by an analog-to-digital converter. The response voltage signal is sampled once when at high level and once when at low level for every circle of the square wave signal by the ADC, and a sample V1 and a sample V2 are obtained respectively, difference of the sample V1 and the sample V2 is taken as a detecting result for one circle. An average value of the detecting result from a plurality of circles may be taken as a final result. Information of electrical impedance is illustrated by the final result because the excitation current signal is constant.

    摘要： A USB converter circuit for converting electrical signals from a key scan circuit (in PS/2 or other formats) into USB signals for a computer while supporting N-key rollover (NKRO) functions. The converter circuit can be implemented as a stand-alone PS/2 to USB keyboard converter or as an integral component of a USB keyboard or KVM switch. The converter circuit includes a converter module that generates keyboard data packets in the USB format having a 16-byte, 64-byte, etc. format representing key press information for up to 8 modifier keys and 14, 62, etc. non-modifier keys, respectively. The converter circuit also includes a USB device controller module which transmits the 16-byte etc. USB keyboard data as one or multiple USB data packets to the host computer. When multiple USB data packets are needed to transmit each keyboard data packet (depending on the USB speed), they are transmitted in consecutive polling periods.
