摘要： Systems and methods sense out-of-plane linear accelerations. In an exemplary embodiment, the out-of plane linear accelerometer is accelerated in an out-of-plane direction, wherein the acceleration generates a rotational torque to an unbalanced proof mass. A rebalancing force is applied to at least one plurality of interleaved rotor comb tines and stator comb tines, wherein the rebalancing force opposes the rotational torque, wherein the rotor comb tines are disposed at an end of the unbalanced proof mass, and wherein the stator comb tines are disposed on a stator adjacent to the end of the unbalanced proof mass. An amount of acceleration is then determined based upon the applied rebalancing force.

摘要： A barrier forming apparatus is deployable through a conduit component in a well. The apparatus has a snap latch that removably couples to a work string. A mandrel element in the apparatus is selectively moveable with the coupling element. A plurality of locator dogs on the apparatus are spring biased and are activated when pressure is applied to a piston in the apparatus, which release the locator dogs. Once activated, the locator dogs engage a first grove the in the conduit component. When the work string is pulled up while the apparatus is held by the locator dogs, a plurality of locking dogs are activated by movement of a mandrel element caused by the work string. The locking dogs engage second grooves in the conduit component. Continued pulling of the work string moves a cone attached to a distal end of the mandrel element, and the moving cone deforms a barrier element positioned between an end of the apparatus' housing and the cone. The deformed barrier element forms a barrier in the conduit component between upper and lower completions. Removal of the barrier is achieved by reversing the steps. The apparatus can be used to isolate an expandable sand screen section below the conduit component.

摘要： The invention is a method and apparatus for controlling the vibration modes of a vibratory rotation sensor (VRS) comprising a resonator and a housing which together serve as the ground potential reference. The resonator has a surface with a conductive region and the housing has a plurality of attached electrodes positioned opposing the conductive region on the resonator. The parameters of the resonator standing-wave vibration pattern are determined by feeding an ac sensing signal to the conducting region on the resonator and obtaining one or more vibration signals while the electric potential of the conductive region on the resonator is maintained within 100 millivolts of ground. Each vibration signal is a replica of the ac sensing signal with amplitude modulation which is a periodic function of the distance from a point in the conducting region of the surface of the resonator to an opposing housing electrode. The frequency of the amplitude modulation is the vibration frequency of the resonator. The parameters of the standing wave are determined from the vibration signals, and these parameters are used in controlling the standing-wave parameters by generating appropriate ac forcing voltages which are applied to the housing electrodes.
摘要翻译：本发明是一种用于控制振动旋转传感器（VRS）的振动模式的方法和装置，该振动旋转传感器（VRS）包括共振器和外壳，它们共同作为地电位基准。谐振器具有带有导电区域的表面，并且壳体具有多个附着的电极，该电极与谐振器上的导电区域相对定位。谐振器驻波振动模式的参数通过将馈电感测信号馈送到谐振器上的导电区域并获得一个或多个振动信号来确定，同时谐振器上的导电区域的电位保持在100毫伏的地面。每个振动信号是具有幅度调制的交流感测信号的副本，其是从谐振器的表面的导电区域中的点到相对的壳体电极的距离的周期函数。振幅调制的频率是谐振器的振动频率。由振动信号确定驻波的参数，并通过产生施加到壳体电极的合适的交流强制电压来将这些参数用于控制驻波参数。

摘要： A locking system for selectively locking two frame members of a window or door to prevent sliding movement of one frame relative to the other. The locking system includes a sleeve and first and second pivotably connected bolt members. A spring urges the bolt members to a position where relative sliding movement between the two frame members is prevented. One of the bolt members can be pivoted and then moved along a line which is perpendicular to the other bolt member in a manner such that the bolt is retained in a retracted position.

摘要： A full bore set down tool assembly provides a housing attached to a packer in a wellbore and aligned with the production zone. A service tool of the tool assembly is attached to a tubing string extending to the surface and is adapted for selective, removable attachment to and positioning within the housing. The tool assembly defines a downstream flow path and a return flow path when the service tool is attached to the housing. A ball valve that is selectively shiftable from the surface opens and closes the return flow path to define a circulate position and a squeeze position. The housing, service tool, and ball valve also define a reverse position. The tool assembly facilitates gravel packing of the annulus between the wellbore casing and the service string including the tool assembly.
