Abstract: The present invention relates to a device and a method for conversion from optical double-sideband modulation signals to optical single-sideband modulation signals. Period-one nonlinear dynamics of semiconductor lasers is utilized to achieve such optical signal conversion. Only a typical semiconductor laser is required as the key conversion unit. The microwave and data quality are maintained or even improved after conversion, increasing detection sensitivity, transmission distance, and link gain of the communication networks. The device is relatively less sensitive to ambient variations, can be self-adapted to changes in operating conditions, and can be applied for a broad range of operating microwave frequency up to at least 80 GHz and a high data rate up to at least 2.5 Gbits/s. The device can therefore be dynamically reconfigured for different communication networks adopting different operating microwave frequencies and different data rates.

The optical fiber includes a plurality of sensing regions which are unclad regions of the optical fiber so that the fiber core is exposed, wherein the noble metal nanoparticle layers are set in each sensing regions.

Abstract: A ball screw capable of sensing a preload is formed of a nut having an internal thread surrounding an imaginary central axis, a screw inserted into the nut and having an external thread surrounding the imaginary central axis, and a plurality of balls are mounted between the internal and external threads in a way that the balls roll therebetween. A mounting hole having a mounting surface therein is formed in the nut. The mounting surface corresponds to the internal thread in a way that it is substantially perpendicular to the imaginary central axis. A force sensor is mounted to the mounting surface. The force sensor can directly sense the preload in real time, so it is uneasily adversely affected by any environmental factor to have more accurate sensing result relatively.

Abstract: A plug connector includes an insulating housing, a terminal module, a middle shielding piece, and a shielding shell surrounding the insulating housing and the terminal module. The terminal module includes a first terminal module and a second terminal module. The middle shielding piece is mounted between the first terminal module and the second terminal module. The terminal module together with the middle shielding piece is assembled to the insulating housing. The middle shielding piece has a base plate. Two portions of two opposite sides of the base plate extend outward and then extend frontward to form two lateral arms. An upper end of a rear surface of each of the lateral arms meanders rearward to form a soldering portion projecting out of the insulating housing. A thickness of the soldering portion is thinner than thicknesses of the base plate and the lateral arms.

Abstract: An all-digital spread spectrum clock generating circuit with EMI reduction effect and a method for controlling the same utilize a digital spread-spectrum clock controlling unit to control a digital controlled oscillator, so that it can directly modulates an output clock frequency. Accordingly, the spectrum of the output clock frequency is spread, and the EMI effect due to the output clock signal is reduced. A spread-spectrum clock controller receives a reference clock counting signal and a dividing clock counting signal generated by a frequency detecting unit. After detecting and judging, the spread-spectrum clock controlling unit modulates and maintains a central frequency of the spread-spectrum clock periodically according to the two counting signals, thereby keeping a stability of the central frequency of the spread-spectrum clock signal and decreasing the complexity of the circuit design.

Abstract: A multi-point temperature sensing method for integrated circuit chips and a system of the same are revealed. The system includes at least one slave temperature sensor embedded at preset positions for measuring temperature of a block and a master temperature sensor embedded in an integrated circuit chip and electrically connected to each slave temperature sensor. Variations of the slave temperature sensor induced by variations of process, voltage and temperature are corrected by the master temperature sensor. Thus the area the temperature sensors required on the integrated circuit chip is dramatically reduced and the stability of the temperature control system is improved. The problem of conventional System-on-a-Chip that only a limited number of temperature sensors could be used due to the area they occupied can be solved.

Abstract: A color degradation compensation method includes the steps as follows. Two images are captured by an image capturing device, wherein the two images have an overlapped area. A semi-Gaussian model is constructed. At least one position in the overlapped area is selected and color values of a plurality of points in the position on each of the two images are read, wherein the points of each image are corresponded to the same position in the overlapped area. A degradation standard deviation of the two color values is calculated by the semi-Gaussian model. The color values of the two images are calibrated to compensated color values through the semi-Gaussian model again in accordance with the degradation standard deviation.
