    • A synchronization mechanism and method for synchronizing remote audio devices that are coupled together with a bus is provided. The synchronization mechanism compares a signal on the bus with a clock signal on the audio device and adjusts the clock in response to the comparison. This allows the synchronization mechanism to accurately synchronize remote audio devices without requiring high precision clocks or other complicated solutions. The synchronization mechanism and method are particularly applicable to synchronizing remote audio devices in a distributed audio system that digitally sample and broadcast for communication purposes. In this application, the synchronization mechanism improves audio quality by synchronizing the sampling and outputting of each audio device on the bus. This improves audio quality by reducing the distortion that occurs as a result of varying sample times.
    • 提供了一种用于使与总线耦合在一起的远程音频设备同步的同步机制和方法。 同步机制将总线上的信号与音频设备上的时钟信号进行比较,并根据比较调整时钟。 这允许同步机制精确地同步远程音频设备,而不需要高精度时钟或其他复杂的解决方案。 同步机制和方法特别适用于在通信数字采样和广播的分布式音频系统中同步远程音频设备。 在该应用中,同步机制通过同步总线上每个音频设备的采样和输出来提高音频质量。 这可以通过减少由于不同的采样时间而导致的失真而提高音频质量。

    • An interaction design system (12) may be used by a designer to design a user interface. The designer supplies the interaction design system with a domain model (22) that contains information characterizing an application in a domain, a user model (24) that contains information characterizing the users of the user interface, a task model (26) that contains task primitives to be performed between the user and the user interface and the type of information required by the task primitives, and a device model (28) that contains information characterizing the interaction delivery devices that are available to deliver the user interface. The interaction design system (10) then matches the interaction delivery devices in the device model (28) to the type of information required by the task primitives and to the information characterizing the users, matches presentation objects (30) to the task primitives and to the information of the domain model (22), and generates the user interface based on the matches (32).

    • For accuracy and reliability reasons, GPS systems have traditionally not been used for critical phases of aircraft navigation and guidance, such as aircraft landings. Accordingly, the inventor devised a ground-augmented GPS system that incorporates a better method for determining the accuracy of its position solution. One exemplary embodiment determines a main position solution and one or more position subsolutions, with the main solution using all broadcast correction data and each subsolution using a respective subset of the correction data. Differences or separations between the main position solution and the subsolution are then used to determine accuracy, or protection, limits for the main position solution. Another embodiment uses Kalman filters to incorporate vehicle motion data into the calculation of the main solution and the subsolutions, enabling the determination of protection limits during periods lost GPS or correction data.
    • 出于准确性和可靠性的原因,GPS系统传统上不用于航空器导航和指导的关键阶段,例如飞机着陆。 因此,发明人设计了一种地面增强的GPS系统,其包括用于确定其位置解决方案的准确性的更好的方法。 一个示例性实施例确定主要位置解决方案和一个或多个位置子解决方案,其中主要解决方案使用所有广播校正数据,并且每个子处理使用校正数据的相应子集。 然后使用主位置溶液和下沉之间的差异或分离来确定主要位置解决方案的精度或保护限值。 另一实施例使用卡尔曼滤波器将车辆运动数据并入到主解决方案和子解决方案的计算中,使得能够在丢失GPS或校正数据期间确定保护限制。

    • A fast pseudo-random number generator, which can be employed in a variety of systems, such as a stream cipher cryptosystem or a Monte Carlo simulation system, includes a linear feedback shift register (LFSR) having a state contained in N storage elements storing N bits of binary data which are separated into w words having word length M. At least two tap sources provide binary data, each tap source has a number of bits which is a multiple of M. The LFSR also includes a linear feedback function coupled to tap sources and providing a temporary value which is a linear function, such as bit-wise exclusive-or, of the binary data provided from the tap sources. The LFSR state is advanced by shifting the binary data in the storage elements by a multiple of M bits and provide the temporary value to fill in storage elements that would otherwise be empty from the shifting.
