| 20100116502 | Tubing Pressure Insensitive Control System - A system isolates a control system for a downhole tool from the internal pressures in the tubing in which the tool is mounted. Opposed seals are used on a moving component in the tool so as to offset pressure induced forces regardless of the internal operating pressure of the tool. In a particular application to a subsurface safety valve the control system can be isolated from tubing pressure by offset seals between the passage and the flow tube or around exposed portions of the operating piston for the flow tube. | 05-13-2010 |
| 20110120727 | SUBSURFACE SAFETY VALVE AND METHOD OF ACTUATION - A downhole valve apparatus includes: a force transmitter configured to move in an axial direction; a valve actuator configured to move in an axial direction, the valve actuator independently movable relative to the force transmitter and physically isolated from the force transmitter; a first magnetic assembly disposed at the force transmitter; and a second magnetic assembly disposed at the valve actuator, the first and second magnetic assemblies configured to repel one another and cause the force transmitter to move the valve actuator when the force transmitter is moved toward the valve actuator. | 05-26-2011 |
| 20110120728 | SUBSURFACE SAFETY VALVE AND METHOD OF ACTUATION - An apparatus for operating a downhole valve includes: a force transmitter configured to move in an axial direction and including at least one first magnetic assembly; a housing including at least one axially elongated passageway formed therein, the at least one first magnetic assembly configured to be disposed within the at least one axially elongated passageway; and a valve actuator configured to move in an axial direction and including at least one second magnetic assembly disposed at the valve actuator, the first and second magnetic assemblies configured to interact so that movement of the force transmitter in the axial direction causes movement of the valve actuator in the axial direction. | 05-26-2011 |

Opposed seals are used on a moving component in the tool so as to offset pressure induced forces regardless of the internal operating pressure of the tool.

| 20100108249 | Method and Apparatus For Making Sealed Pouches - A method and apparatus for making pouches is disclosed. It includes using one or more of the following features: using two servo motors to drive a platen, providing a calibration routine is run at start-up and/or after the machine has been operating; controlling in response to feed back from the servo motor(s) such as feedback indicative of the distance the platen travels; the feedback is not of force exerted by the platen; and/or the platen is controlled to prevent unacceptable fracturing of the film laminate. | 05-06-2010 |

| 20100284633 | Discrete pouch having a closure system secured thereto - A discrete pouch is disclosed having a closure system transversely secured across an open end thereof. The discrete pouch includes first and second major surfaces joined together by a pair of sides. The discrete pouch also has a closed bottom, an open top, and a closure system secured to the second major surface adjacent to the open top. The discrete pouch is designed to have the open top sealed after it is filled with products and the closure system is capable of being opened and closed multiple times. | 11-11-2010 |
| 20100285942 | Machine for securing a closure system onto a discrete pouch - A machine is disclosed for securing a closure system onto a discrete pouch. The machine includes first, second and third stations. The first station is capable of advancing discrete pouches and lifting and folding a portion of a first major surface of each pouch upon itself to form a lip, and exposing an inner surface of a second major surface. The second station is capable of positioning and attaching a closure system transversely across the exposed inner surface. The closure system includes a track having first and second legs each having an outer surface. The first and second legs are joined together by an opening/closing mechanism which includes a movable member capable of being moved back and forth. The third station is located downstream from the second station and is capable of unfolding the lip and securing opposite ends of the lip to the outer surface of the second leg. | 11-11-2010 |
| 20100285943 | In-line method for securing a closure system onto a discrete pouch - An in-line method is disclosed for securing a closure system onto a discrete pouch. The method includes advancing a discrete pouch through a first station in a machine direction with the closed bottom of the pouch being the leading edge and a first major surface of the pouch faces upward. The first major surface is folded upon itself to form a lip having an exposed first surface while a second major surface of the pouch has an exposed inner surface. The method also includes routing the pouch to a second station where a closure system is transversely attached across the exposed inner surface. The closure system includes an opening/closing mechanism. The method further includes routing the pouch to a third station where the lip is unfolded and opposite ends of the lip are secured to the outer surface of the closure system. | 11-11-2010 |

| 20110221664 | VIEW NAVIGATION ON MOBILE DEVICE - Users may view web pages, play games, send emails, take photos, and perform other tasks using mobile devices. Unfortunately, the limited screen size and resolution of mobile devices may restrict users from adequately viewing virtual objects, such as maps, images, email, user interfaces, etc. Accordingly, one or more systems and/or techniques for displaying portions of virtual objects on a mobile device are disclosed herein. A mobile device may be configured with one or more sensors (e.g., a digital camera, an accelerometer, or a magnetometer) configured to detect motion of the mobile device (e.g., a pan, tilt, or forward/backward motion). A portion of a virtual object may be determined based upon the detected motion and displayed on the mobile device. For example, a view of a top portion of an email may be displayed on a cell phone based upon the user panning the cell phone in an upward direction. | 09-15-2011 |
