Title: Pcc enhancements for ciphering support
Inventor: GIARETTA GERARDO
IPC: H04L47/20
Filed: 2009-06-02
Abstract: Systems and methodologies are described that facilitate tunneling within wireless communication systems. Flow identification information is dynamically generated for data flows within a communication system.  This flow identification information assists in determining appropriate flow specific policies to be applied with re-spective data flows. The flow identification information along with the flow specific policies can be communicat-ed to an access mechanism which transmits the data flows in accordance with the flow specific policies. Different aspects relate to using source addresses in combination with the flow identification information for identifying different IP flows originating at a plurality of sources.  The flow identification information also facilitates in ver-ifying if different flows are transmitted in accordance with appropriate rules. The generated data flows are transmitted with respective flow identification informa-tion in order to facilitate the verification process.

IPC: B66F3/46
Filed: 2011-01-14
Abstract: A system and method for leveling a vehicle when stationary. The system includes three zones with a first zone at the front end, and the second and third zones on opposite sides of the vehicle. All zones include leveling jacks, each having a blind side and a rod side. At least one leveling jack is located in the first zone, and at least two leveling jacks are located in each of the second and third zones, straddling the wheel on that side, and the blind sides of the jacks in each zone are connected together. The rod sides of all of the jacks are connected to a common fluid line, which typically is low fluid or pressure free. In operation, once the vehicle is stationary, all of the jacks are extended from a retracted position to an extended position meeting the surface upon which the vehicle is located. Fluid is then applied to the blind side of one of the second and third zone leveling jacks to raise the lower of the two sides, and, if the front end is higher than the rear, fluid to the blinds of the leveling jack in the first zone is reduced, while if the front end is lower than the rear, fluid to the blind side of the leveling jack in the first zone is increased, with the vehicle then being level.

Title: Microstrip antenna for electromagnetic radiation dissipation device
Inventor: TUCEK KEVIN B
IPC: H01Q13/08
Filed: 2009-06-26
Abstract: The present invention is a microstrip antenna design that can be used with an electromagnetic radiation dissipation device that reduces exposure to undesirable electromagnetic radiation. The dissipation device uses a microstrip antenna to capture radiation from an active emission source, such as a cellular telephone when it is transmitting. The device converts the captured radiation into an electric current and dissipates the collected current by spending it to operate a thermal, mechanical, or electrical device. The microstrip antenna comprises several serially connected meandering segments. One or more meandering segments include bends with angles which differ from 90° by less than 5°, and one or more meandering segments include bends with angles which differ from 90° by more than 5°. The overall shape or footprint of the antenna is a modified hourglass so that the microstrip segments near the center of the antenna are narrower than the microstrip segments near the ends of the antenna. In general, the meandering segments include varying angles, which maximizes the operation of the antenna for absorbing undesirable electromagnetic radiation from cellular telephones.

Abstract: A device and a method for controlling a clamping press is provided when clamping a tension member as a function of the clamping force of a reference clamping member. The device has a hollow, cylindrical housing, wherein a piston coupled to the reference tension member is supported longitudinally displaceably along an axis. The housing and the piston encompass a pressure chamber that can be acted upon by a pressure medium for performing an axial stroke motion of the piston against the clamping force of the reference tension member by an inlet, and that can be connected by an outlet to the clamping press. The device further comprises a valve unit for controlling the application of the pressure medium to the clamping press, wherein the valve unit can be directly controlled by the stroke motion of the piston. The method according to the invention provides for clamping the tension member as a function of the clamping force of the reference tension member by the cylinder piston unit, the piston thereof holding the reference tension member in a predetermined stress state. When a uniform stress state is achieved in all tension members in the course of clamping the tension member by a clamping press, the inflow of the pressure medium to the clamping press is directly interrupted by the stroke motion of the piston.

Abstract: A sliding sleeve has a sensor that detects plugs (darts, balls, etc.) passing through the sleeves. A first insert on the sleeve can be hydraulically activated by the fluid pressure in the surrounding annulus once a preset number of plugs have passed through the sleeve. Movement of this first insert activates a catch on a second insert. Once the next plug is deployed, the catch engages it so that fluid pressure applied against the seated plug through the tubing string can moves the second insert. Once moved, the insert reveals port in the housing communicating the sleeve's bore with the surrounding annulus so an adjacent wellbore interval can be stimulated. The first insert may also be hydraulically activated after a preset time after a plug has passed through the sleeve. Several sleeves can be used together in various arrangements to treat multiple intervals of a wellbore.
