    • A technique for determining the charge air temperature within an intake manifold of an internal combustion engine of a vehicle without using a dedicated temperature sensor. The technique includes identifying a non-linear dynamic model based on the physical concepts of thermal transfer and system identification technique. The charge air temperature model uses several available physical measurements from the vehicle, including inlet air temperature, engine coolant temperature, vehicle speed, manifold pressure, engine speed, exhaust gas recirculation condition, and the engine fan on/off state. The model parameters are determined based on specific vehicle characteristics, and collected data from the vehicle. The charge air temperature is predicted by the model at regular predetermined intervals from the physical measurements, the vehicle parameters and the charge air temperature from the previous time. An estimation of an initial charge air temperature when the vehicle is turned on can be obtained based on the available temperature sensor readings when vehicle is turned on and stored data of the charge temperature, and all the measured temperature readings just before the engine was turned off.
    • 一种用于在不使用专用温度传感器的情况下确定车辆内燃机的进气歧管内的增压空气温度的技术。 该技术包括基于热传递和系统识别技术的物理概念识别非线性动态模型。 增压空气温度模型使用来自车辆的几种可用的物理测量,包括入口空气温度,发动机冷却剂温度,车辆速度,歧管压力,发动机速度,废气再循环状况和发动机风扇开/关状态。 模型参数根据特定车辆特性确定,并从车辆收集数据。 从物理测量,车辆参数和前一次的增压空气温度以规定的预定间隔,模型预测增压空气温度。 可以基于车辆开启时可用的温度传感器读数和存储充电温度的数据以及在发动机关闭之前的所有测量温度读数来获得车辆接通时的初始增压空气温度的估计 。

    • A reputation system aids in the prevention of unwanted spam or malicious communications from being sent to a mobile device, such as a cell phone. A collaborative process is used to determine ratings for a collection of source identifications of the communications. The source identifications are caller identifications (IDs) of a corresponding voice or SMS communication. A collection of opinions is maintained regarding the caller IDs. The reputation system then uses a method of making automatic predictions about the caller IDs by collecting caller ID information from many users to populate the database of maintained opinions. As such, caller IDs of users who have sent spam or malicious messages can be blocked by using collaborative information from many users, as opposed to relying on individual users to block unwanted communications.
    • 信誉系统有助于防止不想要的垃圾邮件或恶意通信被发送到诸如手机的移动设备。 协作过程用于确定通信的源标识集合的等级。 源标识是对应的语音或SMS通信的呼叫者标识(ID)。 维护有关呼叫者ID的意见集。 信誉系统然后使用通过从许多用户收集呼叫者ID信息来填充维护意见的数据库来对呼叫者ID进行自动预测的方法。 因此,通过使用来自许多用户的协作信息,可以阻止发送垃圾邮件或恶意邮件的用户的呼叫者ID,而不是依赖于个人用户来阻止不必要的通信。
