    • A system for selecting a user speech profile for a device in a vehicle includes a control module having a speech recognition system and a memory. The speech recognition system is configured to process audio signals and includes a speaker enrollment function configured to create a user speech profile for at least one user. The memory is configured to store a plurality of user speech profiles created by the speaker enrollment function. The system may include an external device configured to transmit a control signal to the vehicle including an identifier. Alternatively, the system may include a user input device configured to receive an input command from a user that includes an identifier. The control module uses the identifier to select a user speech profile from the plurality of user speech profiles and the speech recognition system uses the selected user speech profile to process audio signals from the user.
    • 用于为车辆中的设备选择用户语音简档的系统包括具有语音识别系统和存储器的控制模块。 语音识别系统被配置为处理音频信号并且包括配置成为至少一个用户创建用户语音简档的扬声器登记功能。 存储器被配置为存储由说话者登记功能创建的多个用户语音简档。 该系统可以包括被配置为向车辆发送包括标识符的控制信号的外部设备。 或者,系统可以包括被配置为从包括标识符的用户接收输入命令的用户输入设备。 控制模块使用标识符从多个用户语音简档中选择用户语音简档,并且语音识别系统使用所选择的用户语音简档来处理来自用户的音频信号。

    • One or more vehicle suspension signals, preferably already generated within a controllable suspension system, is utilized to perform switches of the damping state of variable damping shock absorbers in the suspension system while the velocity of the shock absorbers is close to zero velocity. In particular, signals generated by height sensors within a controllable suspension system are utilized as vehicle suspension signals which are filtered to generate signals to enable switching of the shock absorbers while the shock absorbers are close to zero velocity. In addition, performance of the suspension system is improved by utilizing the vehicle suspension signals as one criterion to determine when switching from soft damping to firm damping or from firm damping to soft damping is desirable. Switch enable signals are determined from vehicle suspension signals by filtering at a resonant body frequency and comparison to an appropriate threshold. Soft-to-firm/firm-to-soft switch request signals are determined from vehicle suspension signals by filtering at a resonant wheel frequency and comparison to appropriate thresholds. Preferably, firm-to-soft switches are made after expiration of predefined time periods.
    • 优选地已经在可控悬架系统内产生的一个或多个车辆悬架信号用于执行悬架系统中可变阻尼减震器的阻尼状态的开关,同时减震器的速度接近零速度。 特别地,由可控悬挂系统内的高度传感器产生的信号被用作车辆悬架信号,其被过滤以产生信号,以便在减震器接近零速度时能够切换减震器。 此外,通过利用车辆悬架信号作为一个标准来确定何时从软阻尼切换到固定阻尼或从固定阻尼切换到软阻尼来改善悬架系统的性能。 开关使能信号通过以谐振体频率滤波并与适当阈值进行比较从车辆悬架信号确定。 通过以谐振轮频率滤波并与适当阈值进行比较,从车辆悬架信号确定软到固定/公钥到软切换请求信号。 优选地,在预定义时间段期满之后制作公钥对软交换机。

    • The pipeline packer described herein typically includes a main body adapted for propulsion through the pipeline in an axial direction. A brake shoe support assembly is located on the main body and a plurality of circumferentially spaced brake shoes capable of gripping the interior wall of the pipeline are mounted to the support assembly. Fluid pressure activated means are associated with the brake shoe support assembly for urging the brake shoes radially outwardly into gripping engagement with the pipeline to secure the main body in a desired location in the pipeline against the pipeline pressure forces acting thereon. A pair of annular wedging means are also mounted to the main body for axial movement toward each other as the fluid pressure activated means acts on the brake shoe support assembly to urge the brake shoes into gripping engagement. An annular sealing member of elastomeric material is located between the annular wedging means and is adapted to co-operate with same so as to expand radially outwardly as the annular wedging members move toward each other. The packer also includes fluid pressure supply and control means connected to the fluid pressure activated means so that on demand the brake shoes urged into gripping relationship with the pipeline while at the same time the annular sealing member is expanded into sealing engagement with the pipeline wall.
    • 本文描述的管道封隔器典型地包括适于在轴向方向上推动通过管道的主体。 制动蹄支撑组件位于主体上,并且能够夹持管道内壁的多个周向间隔开的制动蹄安装在支撑组件上。 流体压力激活装置与制动蹄支撑组件相关联,用于将制动蹄径向向外推压成与管道夹紧接合,以将主体固定在管道中的期望位置,抵抗作用于其上的管道压力。 当流体压力致动装置作用在制动蹄支撑组件上以推动制动蹄夹紧接合时,一对环形楔形装置也安装到主体上用于彼此轴向移动。 弹性体材料的环形密封构件位于环形楔形装置之间,并且适于与其相配合,以便随着环形楔形件朝向彼此移动而径向向外扩张。 封隔器还包括连接到流体压力启动装置的流体压力供应和控制装置,使得随着制动蹄被迫与管道成夹紧关系,同时环形密封构件膨胀成与管道壁密封接合。
