    Abstract: A pipeline A/D converter and its single redundancy bit digital correction are provided. The single redundancy bit digital correction includes the following steps: substages except for the last one quantizes input voltage, calculates the residual voltage, which is amplified and shifted to the middle part of the reference voltage range, and outputs to the following substage until the last one, which only quantizes the input voltage; the code and offset code of each substage corresponding to the quantized thermometer code are calculated; the offset codes of all stages are added by weight to get total offset code; and codes of all substages are added by weight, to which the total offset code is added. The comparator offset error is corrected to obtain an output code which identifies the negative or positive overflow of input signals. The A/D converter adopting the above digital correction is provided.

    Abstract: The surface morphology of an LED light emitting surface is changed by applying a reactive ion etch (RIE) process to the light emitting surface. High aspect ratio, submicron roughness is formed on the light emitting surface by transferring a thin film metal hard-mask having submicron patterns to the surface prior to applying a reactive ion etch process. The submicron patterns in the metal hard-mask can be formed using a low cost, commercially available nano-patterned template which is transferred to the surface with the mask. After subsequently binding the mask to the surface, the template is removed and the RIE process is applied for time duration sufficient to change the morphology of the surface. The modified surface contains non-symmetric, submicron structures having high aspect ratio which increase the efficiency of the device.

    Abstract: An eddy-current actuated balancer includes a barrel having a locating wall at one end thereof; two balancing wheels mounted around the barrel and carrying a respective counterweight at the border, a washer set between the balancing wheels, an elastic ring and a lock ring and a pulsed magnetic field generator mounted on each balancing wheel. The balancing wheels, the washer and the elastic ring are clamped between the locating wall of the barrel and the lock ring. Each pulsed magnetic field generator is controlled to generate a pulsed magnetic field acting upon the associating balancing wheel during its rotation for inducing an eddy current that causes the associating balancing wheel to make an angular displacement relative to the barrel for balance adjustment.
