摘要： The present invention provides a low-voltage organic thin film transistor having a gate dielectric layer of ultra-thin metal oxide self-grown on a metal gate electrode by O2 plasma process. The metal gate electrode is deposited on a plastic or glass substrate. By directly oxidizing the gate electrode by using O2 plasma process, the gate dielectric layer of metal oxide is formed with a thickness of several nanometers on the gate electrode. The organic semiconductor layer is deposited on the gate dielectric layer, and source/drain electrodes are formed on the organic semiconductor layer. Before the organic semiconductor layer is formed, an organic molecular monolayer may be formed on the gate dielectric layer by using molecular self-assembly technique. The gate dielectric layer may be formed at room temperature to about 100° C.

摘要： Methods and systems for measuring mechanical property of a vascular wall and a method and system for determining health of a vascular structure are provided wherein local deformation of a vessel wall resulting from physiologic pressures with altered transmural forces is measured. A non-invasive free-hand ultrasound scanning-procedure was performed to apply external force, comparable to the force generated in measuring a subject's blood pressure, to achieve higher strains by equalizing the internal arterial baseline pressure. When the applied pressure matched the internal baseline diastolic pressure, strain and strain rate increased by a factor of 10 over a cardiac cycle. Radial arterial strain was assessed in the vessel wall over the entire deformation procedure using a phase-sensitive, two-dimensional speckle-tracking algorithm. An elastic modulus reconstruction procedure was developed to estimate the non-linear elastic properties of the vascular wall.

摘要： A system and method are disclosed to generate and terminate clock shift modes during initialization of a synchronous circuit (e.g., a delay-locked loop or DLL). Upon initialization, the DLL is entered into a ForceSL (Force Shift Left) mode and an On1x mode (i.e., left shifting on each clock cycle). The feedback clock that tracks the phase of the reference clock (which, in turn, is derived from the system clock) is initially delayed in a coarse phase detector prior to applying it to the coarse phase detection window. Two delayed versions of the feedback clock are sampled by the reference clock to generate a pair of phase information signals, which are then used to establish an advanced phase equal (APHEQ) signal. The APHEQ signal advances onset of the PHEQ (phase equalization) phase and is used to terminate the ForceSL and On1x modes, thereby preventing wrong ForceSL exit due to clock jitter or feedback path overshooting during On1x exit. The avoidance of wrong ForceSL exit and On1x overshooting problems further results in faster DLL locking time.

摘要： A method is disclosed for controlling an output impedance of an electronic device of the type having an impedance control terminal to which an external load is to be connected such that a predetermined value of the voltage at the impedance control terminal controls the output impedance of the device. The method is comprised of comparing a reference voltage to a voltage at the impedance control terminal. A variable count signal representing a count value is produced in response to the comparing. The impedance of a variable impedance circuit is varied in response to the count signal, wherein the impedance of the variable impedance circuit controls the voltage at the impedance control terminal. A device connected in parallel with the variable impedance circuit is periodically operated to change (increase/decrease) the impedance of the variable impedance circuit. An apparatus for performing the method is also disclosed. Because of the rules governing abstracts, this abstract should not be used to construe the claims.

摘要： Provided is a wavelength tunable light source including a semiconductor optical amplifier, a beam steering unit or a beam deflector, and a concave diffraction grating integrated therein. The wavelength tunable light source can be easily implemented since locations to which a beam is diffracted by the concave diffraction grating and at which portions of the beam with different wavelengths have constructive interference form a straight line, not a Rowland circle. Furthermore, wavelength tuning and optical coupling characteristics of the wavelength tunable light source are excellent. Since both single integration and hybrid integration are possible for the wavelength tunable light source, the wavelength tunable light source exhibits superior operating characteristics and high reliability.

摘要： An improved comparator circuit and associated methods are disclosed. In one embodiment, the comparator circuit comprises two voltage-to-time converter circuits, one for each input voltage to be compared, and an arbiter circuit for receiving the time-converted output of each converter. Each converter assesses the magnitude of its input voltage, and outputs a signal that is asserted at a time in inverse proportion to the magnitude of the input voltage. In one embodiment, producing the output signal at the asserted time comprises using the input voltage to gate a transistor whose discharge rate dictates the timing of the output signal. The two output signals arrive at an arbiter circuit whose function is to determine which output arrived at the arbiter first, as is indicative of the higher magnitude input voltage, and to set the output of the comparator accordingly.

摘要： The present invention relates to a backlight unit having a polarization film for performing the function of a reflective polarization film. The backlight unit includes a light source, an optical film and a polarization film. The light source emits a light having a certain wavelength.

Accordingly, the polarization film may be manufactured in great quantities.
