Abstract:
An orthogonal frequency-division multiplexing (OFDM) receiver that has a capability for canceling impulse interference is introduced in the present invention. The OFDM receiver includes an impulse noise remover for receiving incoming signals and canceling the impulse interference and a demodulator to demodulate the incoming signals. The impulse noise remover includes an analog-to-digital converter (ADC) that converts the incoming signals into multiple signal points, a delay line for temporarily storing the signal points, a signal processor for calculating a summation of a number of the signals points, a thresholder for checking if an input level provided by the signal processor according to the summation is greater than a predetermined threshold and a switch for replacing values of the signal points influenced by the impulse interference by zeros if the input level is greater than the predetermined threshold.
Abstract:
This invention relates to a method for maximizing the stone chipping resistance and scratch resistance of a multi-layer finish on an automotive substrate. A colored basecoat is applied to the substrate and directly on top of the basecoat is applied a protective clearcoat having a fracture resistance about equal to or above 26 mN and a plastic deformation resistance about equal to or above 30 mN/μm. The resultant coating in addition to being durable to the elements and having excellent appearance produces a finish with an outstanding balance of scratch and stone chip resistance after application.
Abstract:
A data switching circuit is provided, which reduces power consumption of the source drivers when used together with a dot inversion driving method. The circuit comprises a control unit and a switching unit. Wherein, the control unit provides a switching signal. The switching unit has 2N input terminals and 2N output terminals and receives the switching signal. Assume that N is a positive integer and 1≦i≦N. When the switching signal is in a first state, the switching unit connects the (2i−1)th input terminal and the (2i−1)th output terminal, and connects the 2ith input terminal and the 2ith output terminal. When the switching signal is in a second state, the switching unit connects the 2ith input terminal and the (2i−1)th output terminal, and connects the (2i−1)th input terminal and the 2ith output terminal.
Abstract:
A display control method inputs a plurality of frames into a display, which records a sequential flashing threshold value. Each of the frames has a plurality of pixels. The display control method includes a frames-comparing procedure, a play-mode determining procedure, and a sequential flashing controlling procedure. The frames-comparing procedure generates a motion activity value by way of comparing pixels between two of the frames. The play-mode determining procedure determines whether the two frames are in a relationship of a motion mode or not according to the motion activity value and the flashing threshold value, and therefore generates a sequential flashing controlling signal. The sequential flashing controlling procedure performs a sequential flashing process according to the sequential flashing controlling signal.
Abstract:
The invention provides a method for updating check-node of low-density parity-check (LDPC) codes decoder. The method comprises the following steps: First of all, sort all data that are input into the check-node of LDPC codes decoder to find a minimum absolute value and a second minimum absolute value. Secondly, compare each of all the data to both of the minimum absolute value. If the compared data is equivalent to the current minimum absolute value, the compared data is updated by the secondary minimum absolute value. Otherwise, the compared data is updated by the minimum absolute value.
Abstract:
A multi-stage, variable gain amplifier whose linearity is relatively insensitive to variations in gain control is disclosed. The amplifier includes a primary cascoded pair of transistors for producing a primary output current from an input voltage as a function of a primary cascode control voltage. The amplifier further includes one or more secondary cascoded pairs of transistors coupled to the primary cascoded pair of transistors for producing one or more secondary output currents from the input voltage as a function of one or more secondary cascode control voltages. The output current of the RF circuit is a sum of the primary output current and the one or more secondary output currents.
Abstract:
A universal holding frame provides convenience and safety for certain drill accessories which all have an elongate drivable shaft and a mounted storage barrel. The universal holding frame maintains the mounted storage barrel against rotation with the shaft of the drill accessory. It can contract and extend and be able to fit almost all drills.
Abstract:
A gradient-gauge applicable on golf green comprises a main body and a bulb level. The main body made of a transparent material is provided thereon a pair of horizontal line and perpendicular line, and its one side is parallel with a straight edge of the horizontal line. A pointer is pivotally jointed at the intersection of the horizontal line and the perpendicular line. The bulb level, which is disposed on the main body, is curved and drawn with angle graduations, in which the bulb of the bulb level is in a position corresponding to the perpendicular line in case the main body is laid in a horizontal plane.

A method of coating a photo-catalysis on a surface of a coated substrate, the method comprising the steps of: cleaning the surface of the coated substrate; measuring a temperature near the surface of the coated substrate; mixing for a water content of the colloid solution with TiO2 by a water and the colloid solution with TiO2 to form a mixture and pouring uniformly the mixture into a can of an airbrush; and spraying the colloid solution with the TiO2on the surface of the coated substrate by a shape of micro-foam for decomposing the harmful substances in air as an anti-bacterial, a de-ordorization and an anti-mold function.
Abstract:
A serial-protocol type panel display system is suitable for use in a panel display apparatus. The panel display system includes a pixel-array display unit. Multiple divers are used to drive the pixel-array display unit to display an image. A VGA unit uses a serial protocol for encoding and exports a serial image display signal and a clock signal to the drivers. Wherein, the drivers decode the serial image display signal to obtain multiple desired displaying signals to drive the pixels of the pixel-array display unit.
