Publication number: 20240087222Abstract: An artificial intelligence framework is described that incorporates a number of neural networks and a number of transformers for converting a two-dimensional image into three-dimensional semantic information. Neural networks convert one or more images into a set of image feature maps, depth information associated with the one or more images, and query proposals based on the depth information. A first transformer implements a cross-attention mechanism to process the set of image feature maps in accordance with the query proposals. The output of the first transformer is combined with a mask token to generate initial voxel features of the scene. A second transformer implements a self-attention mechanism to convert the initial voxel features into refined voxel features, which are up-sampled and processed by a lightweight neural network to generate the three-dimensional semantic information, which may be used by, e.g., an autonomous vehicle for various advanced driver assistance system (ADAS) functions.Type: ApplicationFiled: November 20, 2023Publication date: March 14, 2024Inventors: Yiming Li, Zhiding Yu, Christopher B.

Patent number: 10017436Abstract: The present invention provides a method of making 1,1,1,2,3-pentachloropropane comprising: (1) utilizing 1,1,1,3-tetrachloropropane as a raw material and 1,1,1,2,3-pentachloropropane as a solvent to carry out a dehydrochlorination reaction to obtain 1,1,3-trichloropropene, and after the reaction, (2) introducing chlorine gas into the reaction system to carry out a chlorination reaction to obtain 1,1,1,2,3-pentachloropropane. In the present invention, 1,1,1,2,3-pentachloropropane acts as a solvent or a diluent, and may act as an inhibitor to prevent the production of high-boiling residues such as dimers, oligomers or polymers during the dehydrochlorination process. Then, the conversion rate of 1,1,1,3-tetrachloropropane is increased, and consequently, the yield of final product 1,1,1,2,3-pentachloropropane is also increased.Type: GrantFiled: March 26, 2018Date of Patent: July 10, 2018Assignee: Jiangxi Tianyu Chemical Co., Ltd.Inventors: Zhong Zhou, Haipeng Xu, Yiming Yu, Peng Peng, Yaling Zhao, Xichao Wang, Xiaori Yue

Patent number: 7791534Abstract: A generic navigation satellite system (GNSS) signal receiver having a fast time to first fix by calibrating a low power always-on real time clock (RTC). The receiver includes an RTC calibrator having a fraction calculator. The RTC calibrator may also include a time expander. Before the receiver is powered off, the fraction calculator uses the fine resolution of GNSS time for determining a time fraction for RTC time. When the receiver is powered back on, the time expander uses an estimate of RTC time drift during the time that GNSS receiver had power off and the time fraction for calibrating and increasing the resolution of the RTC time for an RTC time tick. A signal navigation processor uses the calibrated RTC time for assisting a first fix with code phase search, integration time periods, resolution of epoch integer and/or location-in-space of GPS satellites.Type: GrantFiled: March 13, 2009Date of Patent: September 7, 2010Assignee: Trimble Navigation LimitedInventors: Xiaorong Zhi, Yiming Yu, Joseph W.

Patent number: 7555032Abstract: A GPS receiver and method using alternating “A” and “B” integration time segments. The polarities of certain GPS data bits are known beforehand and their expected reception times are known. The GPS signal in 10 millisecond “A” time segments and “B” time segments is depolarized according to the known polarities. The depolarized GPS signal during an “A” time period made up of all the “A” time segments is integrated for providing an “A” time period magnitude for each code phase. Likewise, the depolarized GPS signal during a “B” time period made up of all the “B” time segments is integrated for providing a “B” time period magnitude for each potential GPS code phase. The strongest of the time period magnitudes is compared to a correlation threshold for selecting a code phase for signal acquisition.Type: GrantFiled: February 26, 2007Date of Patent: June 30, 2009Assignee: Trimble Navigation LimitedInventors: Peter Van Wyck Loomis, Yiming Yu

Patent number: 7480325Abstract: A GPS receiver for integrating a GPS signal separately in a series of “A” type and “B” type time segments, the “A” segments alternating with the “B” time segments; combining the squares of the magnitudes of “A” time segment integrations corresponding to code phases for forming “A” type combined magnitudes; combining the squares of the magnitudes of the “B” time segment integrations corresponding to code phases for forming “B” type combined magnitudes; and determining an acquisition code phase of the signal from the strongest of the “A” or “B” combined magnitudes. The “A” time segments and the “B” time segments are one-half the period of the data bits of the signal, thereby ensuring that either the “A” time segments or the “B” time segments avoid the nullifying effect of data bit inversions.Type: GrantFiled: February 16, 2005Date of Patent: January 20, 2009Assignee: Trimble Navigation LimitedInventors: Yiming Yu, Peter Van Wyck Loomis
