    • With regard to the exemplary method, a first communication is received from an IPTV subscriber at an IPTV application server via the subscriber's Web-accessible device. The server accesses level of service data for the subscriber and displays a new Web page based on the level of service data. The Web page includes a list of applicable channels. The server also determines whether the subscriber has a set-top box that is powered on. Where the subscriber does have a set-top box and the set-top box is powered off, data received from the subscriber is saved in the database. Where the subscriber does have a set-top box and the set-top box is powered on, the subscriber is allowed to perform a switching function for each applicable and currently viewable channel on a search result list. Finally, a signal to the set-top box to change the channel.
    • 关于该示例性方法,经由用户的可访问网络的设备从IPTV应用服务器从IPTV订户接收第一通信。 服务器访问用户的服务级别,并根据服务级别的数据显示新的网页。 该网页包括适用频道的列表。 服务器还确定订户是否具有通电的机顶盒。 在用户确实有机顶盒并且机顶盒关闭的情况下,从订户接收的数据被保存在数据库中。 在用户确实具有机顶盒并且机顶盒通电的情况下,允许用户对搜索结果列表上的每个可应用且当前可见的频道执行切换功能。 最后,一个信号到机顶盒来改变频道。

    • A method of providing real-time channel searching and switching for IPTV is provided. Initially, a first communication is received from an IPTV subscriber at an IPTV application server upon the subscriber logging in to the server via the subscriber's Web-accessible device. The server communicates with a subscriber database to access level of service data for the subscriber and displays a new Web page for the subscriber based on the level of service data. The Web page includes a list of applicable channels based on a keyword search typed by the subscriber via the subscriber's Web-accessible device. The server also determines whether the subscriber has a set-top box that is powered on. Where the subscriber does have a set-top box and the set-top box is powered off, data received from the subscriber is saved in the database. Where the subscriber does have a set-top box and the set-top box is powered on, the subscriber is allowed to perform a switching function for each applicable and currently viewable channel on a search result list. Finally, a signal to the set-top box to change the channel.
    • 提供了一种为IPTV提供实时信道搜索和切换的方法。 最初,当用户通过用户的Web可访问设备登录到服务器时,在IPTV应用服务器处从IPTV订户接收到第一通信。 服务器与用户数据库通信以访问用户的服务数据级别,并根据服务级别的数据显示用户的新网页。 该网页包括基于通过用户的可访问网络的设备由用户键入的关键字搜索的适用频道的列表。 服务器还确定订户是否具有通电的机顶盒。 在用户确实有机顶盒并且机顶盒关闭的情况下,从订户接收的数据被保存在数据库中。 在用户确实具有机顶盒并且机顶盒通电的情况下,允许用户对搜索结果列表上的每个可应用且当前可见的频道执行切换功能。 最后,一个信号到机顶盒来改变频道。

    • A device for use with a gyroscopic stabilizer for use in an assembly that is moveably connected to a vehicle. The gyroscopic stabilizer has a gyroscope, a skew motor, and a skew motor velocity servo-control system. The gyroscopic stabilizer can control a skew of the assembly based on a torque signal to maintain the assembly in an intended position. The skew motor velocity servo-control system can control the skew motor. The skew motor can move the gyroscope. The gyroscope can provide the torque signal. The device comprises an assembly position determining system, a detector, a state estimator and an output portion. The assembly position determining system can generate an assembly position signal based on one of a position of the assembly, a position of the gyroscopic stabilizer, a position of the gyroscope, a position of the skew motor and a position of the skew motor velocity servo-control system. The detector can detect a skew of one of the assembly, the gyroscopic stabilizer, the gyroscope, the skew motor and the skew motor velocity servo-control system and to generate a skew signal. The state estimator can provide an error signal based on the skew signal. The output portion can provide an output signal to the gyroscopic stabilizer. The output signal is based on the assembly position signal and the error signal.
    • 一种用于与可移动地连接到车辆的组件中的陀螺稳定器一起使用的装置。 陀螺稳定器具有陀螺仪,偏斜马达和偏斜马达速度伺服控制系统。 陀螺稳定器可以基于扭矩信号控制组件的偏斜,以将组件保持在预期位置。 偏斜电机速度伺服控制系统可以控制偏斜电机。 偏斜电机可以移动陀螺仪。 陀螺仪可以提供扭矩信号。 该装置包括装配位置确定系统,检测器,状态估计器和输出部分。 组装位置确定系统可以基于组件的位置,陀螺稳定器的位置,陀螺仪的位置,偏斜电动机的位置和偏斜电动机速度伺服驱动器的位置中的一个产生组装位置信号, 控制系统。 检测器可以检测组件,陀螺稳定器,陀螺仪,斜齿马达和斜马达速度伺服控制系统中的一个的偏斜,并产生偏斜信号。 状态估计器可以基于偏斜信号提供误差信号。 输出部分可以向陀螺稳定器提供输出信号。 输出信号基于装配位置信号和误差信号。
