摘要： A method is provided for augmenting GPS data using an in-vehicle vision-based module. A vehicle position is determined utilizing position-related data obtained from a position module. A position error is estimated on a periodic basis. A determination is made whether the position error estimate exceeds a first predetermined error threshold. Tracking data is generated for the vehicle over a course of travel utilizing captured images from the in-vehicle vision based module. The tracking data is integrated with the position-related data to estimate the vehicle position in response to the position error estimate exceeding the first predetermined error threshold. A determination is made whether the position error estimate decreases below a second predetermined error threshold. The vehicle position is re-determined using only the position-related data when the position error estimate decreases below the second predetermined error threshold.

摘要： A system and method for calibrating a vehicle heading sensor, such as a yaw-rate sensor, when GPS signals are not available using a bias update model that employs a bias gain factor. In order for the bias update model to be accurate, the vehicle should be traveling relatively straight. One embodiment of the present invention uses three thresholds to determine if the vehicle is traveling straight. These thresholds include a yaw-rate threshold, a steering wheel angle threshold and a wheel speed threshold. If all three of the thresholds indicate that the vehicle is traveling straight, then the update bias model can be used to calibrate the yaw-rate sensor.

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： A system and method for authenticating a message transmitted in a vehicle-to-vehicle communications system. The sending vehicle will attach raw GPS data to a transmitted message it receives from GPS satellites that the sending vehicle uses to determine its own position. The transmitted message will also include the position of the sending vehicle that the sending vehicle has determined using the GPS data. The receiving vehicle will use the raw GPS data in the message and an RTK process to determine the position of the sending vehicle. The receiving vehicle will compare the position of the sending vehicle in the message with the position of the sending vehicle determined from the GPS data, and if they match, will authenticate the received message.

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.
