摘要： A positioning method and a positioning apparatus are provided. In this positioning method, a differential global positioning system is used to calculate a double difference of satellite distance in connection with a reference station and a receiver station. A baseline vector pointing from the reference station to the receiver station is calculated according to the double difference of satellite distance and the cosine law. The baseline vector and the position of the reference station are used to calculate the position of the receiver station. Correction coefficients are obtained according to the position of the reference station, the position of the receiver station, and the current time. The position of the receiver station is corrected according to the correction coefficients and the length of the baseline vector.

摘要： A signal modulation device and a signal amplifier cooperative therewith. The signal modulation device includes a local oscillation signal source, a baseband signal source, a first NMOS transistor, and a second NMOS transistor, wherein the first and second NMOS transistors are coupled with the baseband signal source and form a circuit architecture of a Gilbert-cell based differential pair to be directly switched by a differential baseband signal, and a high-frequency signal from the local oscillation signal source is controlled by the baseband signal so as to generate an amplitude-modulation high-frequency signal at an output end. The single-stage signal power amplifier amplifies the amplitude-modulation signal from the preceding circuit so as to increase the magnitude of signals transmitted and simplify the preceding digital/analog signal conversion circuit in a conventional amplitude-modulation circuit.

摘要： Disclosed is a designed and implemented 12-bit 70 Msps pipeline analog-to-digital converter. Two adjacent blocks operate at opposite clock phases to reduce the chip size and power consumption. Since the opposite clock phases are designed to be provided by external devices, the timing between these two clock phases must be accurate. Note that the architecture of pipeline ADC consists of four stages, divided into two groups, wherein two adjacent stages in each group share one 3-bit flash ADC, hence only two 3-bit flash ADCs are required in this scheme. Therefore, there are 6-bit signal produced from each 3-bit flash ADC within one clock phase which consists of two opposite clock phases. And within the same period, the total output of the pipeline analog-to-digital converter would be 12-bit. From the simulation results, when the sampling rate is 70 Msps, this converter consumes 155 mW (TBV) at a ±1.8 V supply.

摘要： A dot-matrix display data refresh voltage charging control method and system is proposed, which is designed for integration to a dot-matrix display device, such as TFT-LCD (Thin Film Transistor Liquid Crystal Display), for controlling a data-refresh process on the dot-matrix display device. The proposed method and system is characterized by the capability of performing data refresh by comparing for the differences between the currently-displayed pixel values and the new pixel values to be used for data refresh to thereby obtain a set of differential voltages for use to be applied to the pixels for data refresh. This feature allows the data-refresh process to use only a low level of differential voltage rather than the full-level of pixel data voltage for data refresh, thus allowing the data-refresh process to be completed in a reduced shorter time period to provide a fast scan speed.

摘要： A detection method for preventing an automobile from colliding is applied to an automobile. The detection method includes the following steps: step (a): providing at least two detection devices, each detection device is used to measure a predetermined information of the automobile. A one-stage linear Kalman filter in each device is used to enhance the signal-to-noise ratio of the predetermined information. In step (b): utilizing the one-stage linear filter to receive the predetermined information and obtain a corrected information from the predetermined information after the signal-to-noise ratio is enhanced. In step (c): calculating the corrected information to obtain a component information having vector components of a first direction and a second direction. In step (d): enhancing the signal-to-noise ratio to enable the component information to be a contrast information. Accordingly, the convergence time of calculating the contrast information can be substantially reduced. The position variation of the surrounding moving objects can be accurately estimated to prevent the sudden collision in a short time.

摘要： A direct injection-locked frequency divider circuit with inductive-coupling feedback architecture is proposed, which is designed for integration to a high-frequency circuit system with a high operating frequency such as 24 GHz (gigahertz), for providing a frequency-dividing function. The proposed frequency divider circuit comprises an injection-locked oscillator (ILO) circuit module and a pair of buffer-stage circuits, wherein the ILO circuit module further includes a signal-injection circuit, a cross-coupled switching circuit, and a variable-capacitance tuning circuit. The proposed circuit architecture is characterized by the circuit arrangement of a direct-injection architecture and an inductive-coupling feedback architecture by coupling the inductive elements of the buffer-stage circuits to the inductive elements of the variable-capacitance tuning circuit in the ILO circuit module. These features allow the proposed frequency divider circuit to have higher operating frequency with wider frequency locking range, low power consumption, and small integrated circuit layout area.
