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.

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.

摘要:
The invention relates to (among other things) oligomer-PTK inhibitor conjugates and related compounds. A compound of the invention, when administered by any of a number of administration routes, exhibits advantages over PTK inhibitor compounds lacking a water soluble, non peptidic oligomer.
摘要:
The invention provides methods for the preparation of small molecule drugs that are chemically modified by covalent attachment of a water-soluble oligomer obtained from a water-soluble oligomer composition. Such drugs are produced through modification of a synthetic pathway to attach the oligomer to an intermediate compound followed by completion of the synthetic path.
摘要:
A keyboard-video-mouse (KVM) switch system capable of invoking an on-screen display menu or a hotkey menu with one keystroke rather than a sequence of keystrokes. The KVM switch system includes a KVM processor and at least one menu key. The menu key generates at least one trigger signal based on the keystroke and at least one command is issued to the KVM processor. The KVM processor controls an OSD module and an OSD output control circuit according to the received command to invoke the menu. The OSD module generates the video signals constituting the menu (either OSD menu or hotkey menu). The OSD output control circuit enables the video signals of the menu to be displayed on the monitor of the console.
