摘要： A system and method for calibrating the bias and scale factors of a heading rate sensor, such as a yaw-rate sensor, using GPS signals. The system receives wheel speed or rotation signals, a vehicle odometer reading, GPS signals and yaw-rate signals. The system includes a wheel-slip detection processor that determines whether there is wheel-slip based on the wheel speed signals and the GPS signals. The system also includes a wheel-based acceleration processor that estimates vehicle acceleration. The system also includes a differential odometry processor that determines vehicle heading based on wheel speed. The system also includes a GPS reference data validation processor that determines whether the GPS signals are valid using the estimated vehicle acceleration and wheel speeds. The valid GPS signals are then used to calibrate the yaw-rate sensor signals, which can be used for vehicle heading purposes.

摘要： A portable and adjustable child potty is invented and described. The invention provides the perfect combination of utility, efficiency, and hygiene. The device can be adjusted to suit users of different ages and body sizes in terms of its height, width, and length. The invented device can be packaged to a Travel Size such that it takes very little space for transportation. Size adjustment and Travel size to usage size changes can be done using a series of easily adjustable locks that can be operated by hand without the use of particular tools. The device is constructed using pipes such that a length of each arm can be adjusted by moving parts of the arms with respect to each other and locking them at a preferred setting. The potty seat can also be folded and contracted to a Travel Size. The device uses a biodegradable and disposable bag to collect the waste. A particular embodiment of the device may include height adjustable arm rests and a back rest. The device may also be used with an optional activity surface. While adult supervision of the use is always required, the anti-roll base and pelvic belt provide additional stability for the use with young children.
摘要翻译： 便携式和可调节的儿童便盆被发明和描述。 本发明提供了效用，效率和卫生的完美结合。 该装置可以根据其高度，宽度和长度进行调整，以适应不同年龄和身体尺寸的用户。 本发明的装置可以被包装到行驶尺寸，使得运输空间很小。 尺寸调整和使用尺寸变化的行驶尺寸可以使用一系列易于调节的锁，可以手工操作而不使用特定工具。 该装置使用管道构造，使得每个臂的长度可以通过相对于彼此移动臂的部分并将其锁定在优选的设置来调节。 便盆座也可以折叠并收缩到旅行尺寸。 该设备使用可生物降解和一次性袋收集废物。 设备的特定实施例可以包括高度可调扶手和靠背。 该设备也可以与可选的活动表面一起使用。 虽然始终需要成人监督使用，但抗卷底座和骨盆带为幼儿使用提供了额外的稳定性。

摘要： A method and system is provided for determining a relative position between a host vehicle and a remote vehicle using an indirect assisting entity technique. A GPS position of the host vehicle and a remote vehicle are obtained. A number of common satellites providing GPS data to the host vehicle and the remote vehicle are determined. An indirect-assisting entity is identified having a common number of satellites in communication between the host vehicle and remote vehicle, respectively, which is greater than the number of common satellites between host vehicle and the remote vehicle. A relative position is determined between the host vehicle and the indirect-assisting entity, and the remote vehicle and the indirect-assisting entity. A position of the host vehicle relative to the remote vehicle is determined as a function of the determined position of the host vehicle and remote vehicle relative to the indirect-assisting entity.

摘要： A traffic flow advisory system includes a locating device for identifying a position of a driven vehicle. A communication device exchanges vehicle position data, speed data, and heading data with remote vehicles. A processor constructs a traffic flow rate in a plurality of road lanes based on the position data and speed data. A human machine interface indicates to a driver of the driven vehicle the traffic flow rate of each of the road lanes.
