    • A piezoelectric pump includes a casing formed of a plurality of metallic members welded and thus joined together, a piezoelectric element dividing an internal space of the casing into a working space and a back pressure space, and internal components formed of resin, and provided between the casing and the piezoelectric element and holding the piezoelectric element. The internal components are formed of workable and moldable resin. The internal component defines a perimeter of the working space and the internal component defines a perimeter of the back pressure space. The internal components are arranged opposite each other to form a recess therebetween to receive and thus hold the piezoelectric element therein.

    • Implementations are disclosed for using magnetometer measurements to estimate bias for angular rate measurements provided by an angular rate sensor (e.g., a gyro sensor). In some implementations, a bias estimator running on a device is configured to determine if the device is rotating based on the magnetometer measurements. If the device is not rotating, a dynamic bias is calculated and added to a temperature compensated static bias to provide a total angular rate measurement bias. The total angular rate measurement bias can be provided to an attitude estimation system where it is used to update an attitude (orientation) of the device. In some implementations, the angular rate measurements are used to determine if the device is oscillating according to a threshold value. If the device is not rotating and the device is oscillating according to a threshold value, the static bias is updated in a calibration table.
    • 公开了使用磁力计测量来估计由角速率传感器(例如,陀螺仪传感器)提供的角速率测量的偏差的实现。 在一些实现中,在设备上运行的偏置估计器被配置为基于磁力计测量来确定设备是否正在旋转。 如果器件不旋转,则计算动态偏置,并将其加到温度补偿静态偏置上,以提供总角速度测量偏置。 总角度测量偏差可以提供给姿态估计系统,其中它用于更新装置的姿态(取向)。 在一些实施方案中,使用角速率测量来确定装置是否根据阈值振荡。 如果设备不旋转并且设备根据阈值振荡,则静态偏差在校准表中更新。

    • A method for session adding during interworking between a CSI terminal and an IMS terminal in a packet network is disclosed, which includes the following steps: a calling terminal initiating a session request to a called terminal, and a home domain S-CSCF of the called terminal forwarding the session request to a interworking control function entity in the local domain which controls the interworking; the interworking control function entity correlating and matching the existing sessions after receiving the session request; and performing session adding operation according to a result of the correlating and matching. Further disclosed are an apparatus for session adding, and a packet network system for the session adding. In the embodiments of the invention, a second session initiated by the calling terminal may be terminated on the same terminal as the first session; or, the first session initiated by the calling terminal and the existing original first session may be merged into an IMS session on the Called Network side, and the IMS session may be terminated to a called terminal. By using the invention, a CSI terminal may initiate a multimedia session to an opposite IMS terminal.
