    摘要： A scanning device processes a multi-point simultaneous acquisition. The acquisition is processed for an infra-red diffuse optical tomography. An intensity modulated light is used with a frequency domain analysis theorem to obtain a reconstructed scanning image. The fibers are capable of a vertical movement and a radial movement. Thus, a precise image showing optical-information data is obtained with a low cost, even through scanning at a minimal angle.

    摘要： Structures and methods for providing a temperature independent constant current reference are provided. A constant Gm circuit is disclosed with embodiments including a voltage controlled resistor providing a current into a current mirror, the current mirror sinking a reference current at its output. By providing a feedback loop that controls the voltage controlled resistor, a temperature compensated circuit may be obtained. The temperature dependence of the voltage controlled resistor is positive and the feedback circuitry maintains this resistor at a value that compensates for the negative temperature dependence of the current mirror circuit. The reference current is thus obtained at a predetermined level independent of temperature. A method for providing a reference current is disclosed wherein a voltage dependent resistor is provided supply current to a current mirror, the voltage dependent resistor receiving a feedback voltage from the current mirror and the feedback controlling the resistor so that a temperature independent reference current is obtained.

    摘要： An image processing method is provided. The image processing method includes obtaining a least significant bit (LSB) associated with a pixel block. Further, two bits are reduced from a bit number of each of the pixels of the pixel block. Thereafter whether to carry the pixel or not is determined according to the LSB. When the LSB is 01 or 11, the carry manners of each pixel of the pixel block in two consecutive frames are asymmetric one to another. Further, under the conditions of when the LSB is 01 and 11, respectively, the carry manners of the pixels of the pixel block mutually compensate. Therefore, the display performance of a display is improved.

    摘要： A Phase Lock Loop (PLL) with gain control is provided. The PLL has a dual-path configuration, where a first and a second VCO control voltage are generated in response to a phase or frequency difference between a PLL input signal and an output signal. The PLL comprises a dynamic voltage gain control (DVGC) unit and a voltage-to-current (V2I) unit, where the DVGC creates a baseline reference current in response to the first VCO control voltage and the V2I provides a substantially linear current in response to the second VCO control voltage. The currents from the DVGC and V2I are combined and fed into a current-controlled oscillator, which generates a PLL output frequency signal. Frequency gain of the VCO is substantially reduced, thus providing a PLL with improved tuning precision.

    摘要： An electric device includes a main body, a supporting crutch and a pivot mechanism connecting the body to the crutch. The body is rotated around the crutch through the pivot mechanism. The pivot mechanism includes first and second bearing shims. The first bearing shim has a limiting salient, which has a first sidewall, a second sidewall and an inclined surface. The inclined surface is tilted from the second sidewall to the first sidewall. The second bearing shim has a sliding salient. When the sliding salient is disposed on the first/second sidewall, the main body is positioned at a first/second position. The sliding salient crosses the first sidewall and slides on the inclined surface to the second sidewall by a first force. The sliding salient crosses the second sidewall and slides on the inclined surface to the first sidewall by a second force larger than the first force.
