Abstract:
A display device detects a touched position by making use of a inducing element and a counter electrode. The voltage produced by the counter electrode is able to affect a conductivity of the channel of the inducing element corresponding to the touched position. The inducing element and a readout circuit are disposed on a substrate of the display device. The counter electrode and a shielding element are both corresponded to the inducing element. The channel of the inducing element corresponding to the touched position changes the conductivity due to the voltage produced by the corresponding counter electrode, and an inducing signal is then generated. The inducing signal is furnished to the readout circuit for signal processing, and a readout signal is generated for analyzing the touched position.
Abstract:
Auto focus methods for electronic cameras are disclosed. The method of the present invention obtains and compares evaluation values (high frequency component (HFC)) corresponding to desired image signals from left or right locations relative to a center of a zoom lens of an electronic camera, thereby locating the maximal evaluation value. The location corresponding to the located maximal evaluation value is an optimum focus location.
Abstract:
The invention relates to a method for reconstructing a fully sampled k-space data set. An undersampled GRAPPA scan of a subject is performed in a parallel MRI system using a set of receiver coil elements and corresponding receiver channels to obtain a reduced k-space data set. Autocalibration samples in k-space for each receiver channel are obtained and a GRAPPA reconstruction kernel β is calculated from the reduced k-space data set and autocalibration samples. Missing k-space lines are reconstructed to obtain a reconstructed k-space data set which together with the reduced k-space data set fully samples each channel of k-space. Each line is reconstructed using a regularized GRAPPA reconstruction if prior k-space information is available and using an unregularized GRAPPA reconstruction if no prior k-space information is available. The regularized GRAPPA reconstructions are performed preferably using a Tikhonov regularization framework.
Abstract:
A pixel region is surrounded in any adjacent scan lines and any adjacent data lines. Two thin film transistor (TFT) groups that are controlled by different scan lines are located in each pixel region. The two data lines respectively send different polarity data to the pixel region through the two TFT groups. At least one capacitor is used to couple with the two TFT groups for providing a coupling effect to make sure the voltage in the two connection points simultaneously goes up and down.

Abstract:
An optical storage device and a blank detection method thereof are disclosed. An RF signal is obtained from an optical disc. A various gain amplifier amplifies the RF signal based on a control signal. An analog to digital converter samples the amplified RF signal to obtain a data signal. An auto gain controller updates the control signal based on amplitude of the data signal. A blank detector detects blankness of the data signal based on a threshold. The threshold is provided by a threshold generator based on the control signal. If the amplitude of the data signal does not exceed the threshold, the blank detector sends a hold signal to suspend update of the control signal.
Abstract:
A code tree of two-dimensional orthogonal variable spreading factor (2D-OVSF) code matrices for a multicarrier direct-sequence code-division multiple-access (MC-DS/CDMA) communications system is generated by providing two sets of 2×2 orthogonal matrices {A(1)(2×2), A(2)(2×2)} and {B(1)(2×2), B(2)(2×2)}. The first set of 2×2 matrices is used to generate a pair of sibling nodes in the code tree that respectively represent matrices A(1)(2×2α) and A(2)(2×2α) by iterating the relationship: A(1)(2×21+β)=[A(1)(2×2β)A(2)(2×2β)], The matrices A(1)(2×2α) and A(2)(2×2α) are A(2)(2×21+β)=[A(1)(2×2β)−A(2)(2×2β)]. used to generate a child node of one of the sibling nodes. The child node contains an M×N matrix, which is found by iterating the relationship: A(i−1)(O×P)=[B(1)(2×2){circle around (×)}A(i/2)(0/2×P/2)] where {circle around (×)} indicates a Kronecker product. A(i)(O×P)=[B(2)(2×2){circle around (×)}A(i/2)(0/2×P/2)],

A circuit for reducing the risk of electrostatic damage to flat panel displays during manufacture and use. A plurality of common voltage coupling points is provided for each of the plurality of driver integrated circuit, arranged to minimize the maximum distance between a signal line and a common voltage coupling point. This significantly reduces the potential for damage to the display by electrostatic discharge due to excessive active area voltage.

This invention is a rewritable near-field optical medium using a zinc oxide nano-structured thin film as the localized near-field interaction layer. This rewritable near-field optical medium is a multilayered body at least comprising: (a) a substrate of transparent material; (b) a first protective and spacer layer formed on one surface of the substrate, which is made of transparent dielectric material; (c) a zinc oxide nano-structured thin film which is capable of causing localized near-field optical interactions; (d) a second protective and spacer layer formed on the localized near-field optical interaction layer, which is also made of transparent dielectric material; (e) a rewritable recording layer; (f) a third protective and spacer layer formed on the rewritable recording layer, which is also made of transparent dielectric material. Ultrahigh density near-field optical recording can be achieved by the localized near-field optical interactions of the zinc oxide nanostructured thin film that is in the near-field region of the rewritable recording layer.
