    • A hydrostatically set packer is disclosed. The actuating piston is locked for run in by a lock sleeve and lock dog arrangement. When the desired depth is reached well pressure is built up to break a rupture disc to allow hydrostatic pressure to act on one side of a lock sleeve. The other side of the lock sleeve is exposed to a chamber under atmospheric or low pressure. Movement of the lock sleeve releases the lock dog allowing piston movement to set the packer. The lock sleeve has a labyrinth seal so that seal leakage below a predetermined level will not prematurely activate the piston lock and prematurely set the packer. A variety of designs for the labyrinth are described.
    • 公开了一种静压式封隔器。 致动活塞被锁定以通过锁定套筒和锁定装置进入。 当达到所需的深度时,建立了压力以打破破裂盘,以允许静水压力作用在锁定套筒的一侧上。 锁定套筒的另一侧在大气压或低压下暴露于室内。 锁定套的移动释放锁定爪,允许活塞移动来设置封隔器。 锁定套筒具有迷宫式密封,使得低于预定水平的密封泄漏不会过早地激活活塞锁并且过早地设置封隔器。 描述了迷宫的各种设计。

    • A mobile phone that uses OS virtualization for minimizing power consumption in mobile phones is provided. Apparatus and methods may involve conserving processor power in a mobile phone according to the invention may include the following steps. A first step may be awakening a first processing core from a low power state in response to a first operating system (OS) thread. A following step may include processing the first OS thread using the first processing core. A next step may include determining whether utilization of the first processing core over a first time period has exceeded a predetermined threshold. The method may also include awakening a second processing core from a low power consumption state if utilization of the first processing core over a first time period has exceeded a predetermined threshold.
    • 提供了一种使用操作系统虚拟化以最小化手机功耗的手机。 根据本发明的装置和方法可能包括节省移动电话中的处理器功率可以包括以下步骤。 响应于第一操作系统(OS)线程,第一步骤可以从低功率状态唤醒第一处理核心。 接下来的步骤可以包括使用第一处理核来处理第一OS线程。 下一步骤可以包括确定在第一时间段内第一处理核心的利用率是否超过预定阈值。 该方法还可以包括如果在第一时间段内的第一处理核心的利用已经超过预定阈值,则从低功耗状态唤醒第二处理核心。

    • A method and apparatus are provided for passing configuration information over a network. In one embodiment, the configuration information is passed between a DHCP server and a DHCP client and includes parameters not formally defined within DHCP. The parameters are therefore encoded into a vendor-specific portion of a DHCP message using at least one triplet comprising a code field, a length field, and a value field. The value field comprises a set of one or more name-value pairs. The code field includes an indication of encryption of the value field. In another embodiment, a fixed-function appliance device is attached to a network, and is booted using boot code and a configuration stored locally to the device. The device then downloads a network configuration, which is compared to the locally stored configuration. If the network configuration is different from the locally stored configuration, the network configuration is stored locally to the device. The device is then rebooted using the stored network configuration.
    • 提供了一种通过网络传递配置信息的方法和装置。 在一个实施例中,配置信息在DHCP服务器和DHCP客户端之间传递,并且包括在DHCP中没有正式定义的参数。 因此,使用至少一个包括代码字段,长度字段和值字段的三元组将参数编码到DHCP消息的供应商特定部分。 值字段包括一组一个或多个名称 - 值对。 代码字段包括值字段的加密指示。 在另一个实施例中,固定功能设备设备附接到网络,并且使用引导代码和本地存储在该设备上的配置来引导。 该设备然后下载一个网络配置,与本地存储的配置进行比较。 如果网络配置与本地存储的配置不同,则网络配置本地存储在设备上。 然后使用存储的网络配置重新启动设备。
