Patent number: 11988199Abstract: The invention discloses a power generating device and an operation method thereof based on ocean temperature difference, which belong to the field of ocean energy utilization, and include a negative thermal expansion body, a rope and a generator. The negative thermal expansion body is connected to the rope, and the rope is connected to the generator simultaneously. The negative thermal expansion body is in a contracted state when in the hotter upper seawater close to the sea surface, and the difference obtained by deducting buoyancy from gravity is relatively large. The negative thermal expansion body is in an expanded state when in colder deep seawater, and the difference obtained by deducting buoyancy from gravity is relatively small. The unbalanced force on the rope will drive the rope to move, and the generator will be driven to generate power through the rope.Type: GrantFiled: August 11, 2022Date of Patent: May 21, 2024Assignee: HUAZHONG UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Yue Shen, Jiangjiang Duan, Jintao Meng, Zhe Deng, Xueting Liu

Patent number: 7693211Abstract: Fast Fourier Transform (FFT) based Phase Lock Loops (PLLs) are provided for use in navigational signal receivers. In an embodiment, a navigation receiver correlates a received navigational signal with a locally generated signal into correlation samples, e.g., one-millisecond correlation samples. The navigation receiver includes a FFT based PLL that corrects phase shifts in the correlation samples due to the Doppler frequency by considering both the Doppler frequency and its rate of change, which are obtained from a FFT computation with interpolation. The phase corrected correlation samples are then integrated over a length of a navigation data bit, e.g., 20 milliseconds, to determine the sign of the data bit of the received signal. In another embodiment, a soft decision feedback technique involving integration extending over the present data bit and several prior data bits is used to determine the sign of a present data bit of the received signal.Type: GrantFiled: April 20, 2006Date of Patent: April 6, 2010Assignee: SIRF Technology Holdings, Inc.Inventors: Chi-Shin Wang, Yue Meng Chen, Zhike Jia

Patent number: 7477189Abstract: Provided herein are systems and methods for achieving long coherent integration in a navigational receiver to improve the sensitivity of the receiver and enable the receiver to acquire, reacquire and track signals under very weak signal conditions. In an embodiment, phase compensation is computed based on estimated Doppler frequency, rate of change of the Doppler frequency with time, and second order rate of change of the Doppler frequency. The Doppler frequency may be computed from an orbital model or ephemeris. This phase compensation is used to compensate samples of the input signal for changes in the phase due to the Doppler frequency. Frequency components of the phase-compensated samples are then computed using a frequency analysis such as a Fast Fourier Transform (FFT). The maximum frequency component is taken as an error frequency and used to compensate the samples of the input signal for residual frequency error.Type: GrantFiled: March 30, 2007Date of Patent: January 13, 2009Assignee: SiRF Technology Holdings, Inc.Inventors: Chi-Shin Wang, Zhike Jia, Yue-Meng Chen, Jian Cheng, EnYuan Tu

Patent number: 6887144Abstract: An element-doped diamond crystal is disclosed herein. The crystal includes at least one dopant element which has a greater concentration toward or near an outermost surface of the crystal than in the center of the crystal. The concentration of the dopant element is at a local minimum at least about 5 micrometers below the surface. The concentration-profile of the dopant element for these diamond crystals causes an expansion of the diamond lattice, thereby generating tangential compressive stresses at the surface of the diamond crystal. These stresses beneficially increase the compressive fracture strength of the diamond.Type: GrantFiled: February 14, 2001Date of Patent: May 3, 2005Assignee: Diamond Innovations, Inc.Inventors: Mark Philip D'Evelyn, Dong-Sil Park, Thomas Richard Anthony, Clifford Lawrence Spiro, Yue Meng, Christopher Allen Long
