摘要： A spatially distributed MEMS inertial sensor array is designed to reduce or cancel measurement errors and to increase the signal detection accuracy. By combining the measurements from a pair of sensors having sensing axes in two different, non-orthogonal directions, the correlated error due to the environmental changes are cancelled or reduced and the uncorrelated random noise is also reduced by the square root of two. By sequentially sampling the sensor array in the time domain, the number of the ADC circuits can be largely reduced. A two dimensional signal processing method is used to process the sensor array output data, in order to further reduce the remaining errors. Namely, one dimension uses the outputs from multiple spatially distributed sensor sets and the other dimension is the time domain. The signal to noise ratio is increased by using the signal correlation in both the spatial domain and the time domain.
摘要翻译：空间分布式MEMS惯性传感器阵列设计用于减少或消除测量误差并提高信号检测精度。通过将来自具有感测轴的一对传感器的测量结合在两个不同的非正交方向上，由环境变化引起的相关误差被消除或减少，并且不相关的随机噪声也被二的平方根减小。通过在时域中顺序采样传感器阵列，可以大大减少ADC电路的数量。使用二维信号处理方法来处理传感器阵列输出数据，以进一步减少剩余误差。也就是说，一维使用来自多个空间分布的传感器组的输出，另一个维度是时域。通过在空间域和时域中使用信号相关来增加信噪比。

摘要： A system, a method and a computer readable storage medium for pre-processing data collected from one or more data sources more accurately summarize data. During the pre-processing, multiple raw data are summarized into a pre-processed datum. By using the pre-processed data entries, more accurate trend data may be generated. Alternatively, data entries are indexed and selectively retrieved based on indices. Decimation of data points are performed based on the indices without retrieving all the data sets from the database, reducing the data access time for returning a query result. Additional data sets may also be retrieved efficiently from the database using the indices.

摘要： An antenna assembly for receiving the GPS signals in a global positioning system (GPS) receiver module automatically orients the antenna to better receive the GPS signals. The antenna is oriented by a positioner (e.g., a counterweight) that automatically rotates a frame on which the antenna is mounted. The GPS receiver module may also include multiple antennas oriented in different directions to maintain good reception of the GPS signals in any position. The multiple antennas are oriented in a manner so that the poor reception range an antenna is covered by other antennas. Signals from multiple antennas may be combined or chosen for processing by a GPS processor. Also, multiple GPS receiver modules may be deployed in close proximity so that wireless communication between the GPS receiver modules may be established.

摘要： A plurality of interactive modules are disposed at spaced locations to form an adaptive wireless network. Each module is capable of receiving transmissions of messages or data packets from other modules, and of transmitting messages or data packets to other modules for forming selected transmission paths via one or more modules toward a base station. Upon failure of a transmission path, a module not capable of transmitting a message along a transmission path toward the base station, transmits a message to other of the plurality of modules to form a new transmission path via such other module.

摘要： A method and system updates a network of sensors remotely through the use of a communication link. The sensors to be updated as well as data files to perform the updating are selected at a base station. The selected sensors are notified of the upcoming update by the base station and may accept or reject the update. The sensors that approve the update then receive data files through the communication link. The sensors notify the base station of any missing data files, which are then retransmitted to all sensors that may be missing data files from the first transmission. After the sensors receive all data files, the update is initiated.

摘要： A three-dimensional position and orientation tracking system uses accelerometers to measure acceleration of a moveable object (e.g., a head-mounted display unit or a data glove). A tracking processor generates both position and orientation information on the object relative to a simulation environment as a function of the acceleration data. In one embodiment, a simplified radar-based tracking system is disposed relative to the object and periodically provides additional tracking data on the object to the tracking processor. The tracking processor uses the additional data to correct the position and orientation information using a feedback filter process. The position and orientation information signals generated can be used, for example, in a simulation or virtual reality application. Position and orientation information is received by a simulation processor relative to the object. The simulation processor modifies a simulation environment as a function of the position and orientation information received. Modified simulation environment information (e.g., video and/or audio information) is then presented to a user.
