    • A switching apparatus, system, and method configured to operate at least a dual line downhole tool via a single pressure source are provided. The switching apparatus may comprise a housing configured to contain a switching piston actuated by a fluid pressure source. The apparatus may further contain a switching valve comprising a first and second coupling passageway coupled to a switching valve housing comprising four ports. The switching piston may actuate the switching valve, alternating the coupling between a first configuration in which the four ports are communicatively coupled into two sets of ports and a second configuration in which the four ports are communicatively coupled into an alternate two sets of ports. The first configuration may configure the fluid pressure source to actuate the downhole tool in a first manner and the second configuration may configure the fluid pressure source to actuate the downhole tool in a second manner.
    • 提供一种开关装置,系统和方法,其被配置为经由单个压力源至少操作双线井下工具。 开关装置可以包括构造成容纳由流体压力源致动的开关活塞的壳体。 该装置还可以包括切换阀,该切换阀包括联接到包括四个端口的切换阀壳体的第一和第二联接通道。 切换活塞可以致动切换阀,在第一配置之间交替耦合,其中四个端口可通信地耦合到两组端口中;以及第二配置,其中四个端口可通信地耦合到备用的两组端口中。 第一配置可以构造流体压力源以第一方式致动井下工具,并且第二配置可以构造流体压力源以第二方式致动井下工具。

    • The invention provides a method of allocating memory in a wireless communication system. The method includes the steps of loading an application into a wireless communication device, compiling at least a portion of the application into native instructions, determining a runtime sensitivity of the native instructions, determining availability of internal memory, and inserting at least a portion of the native instructions into the internal memory at runtime based on the determined availability of internal memory and the runtime sensitivity determination. An associated computer usable medium and a wireless communication device are disclosed.
    • 本发明提供了一种在无线通信系统中分配存储器的方法。 该方法包括以下步骤:将应用程序加载到无线通信设备中,将应用的至少一部分编译成本机指令,确定本地指令的运行时灵敏度,确定内部存储器的可用性,以及插入至少一部分 基于所确定的内部存储器的可用性和运行时灵敏度确定,在运行时将内部存储器的本地指令传送到内部存储器。 公开了一种相关的计算机可用介质和无线通信设备。
