Inventor: O'MALLEY EDWARD J
IPC: E21B47/12
Filed: 2007-11-06
Abstract: Devices and methods for setting a packer inside a wellbore with little appreciable reduction of the useable area of the wellbore. The outer casing or liner of the wellbore contains one or more integrated casing coupler joints having an increased diameter chamber portion. A large bore packing element is carried within the increased diameter chamber portion. The packing element may be selectively actuated to form a seal against an interior tubular member. Because the packing element is located within the chamber portion of the casing coupler, the packer may be set while saving useable cross-sectional area within the casing.

Abstract: This invention provides a Cu-Ni-Si-Co-base alloy possessing excellent strength, electroconductivity and press punchability. The Cu-Ni-Si-Co-base alloy is a copper alloy for an electronic material and comprises Ni: 1.0 to 2.5% by mass, Co: 0.5 to 2.5% by mass, and Si: 0.30 to 1.2% by mass with the balance consisting of Cu and unavoidable impurities. The observation of a cross section parallel to the rolling direction of the copper alloy, for a variation in composition and the area ratio of second phase particles having a diameter of not less than 0.1 µm and not more than 1 µm, shows that the middle value .rho. (% by mass) of the amount of [Ni + Co + Si] is 20 (% by mass) <= .rho. <= 60 (% by mass), the standard deviation .sigma.(Ni + Co + Si) is .sigma.(Ni + Co + Si) <= 30 (% by mass), and the area ratio S (%) is 1% <= S <= 10%.

Title: Scheduling request transmission supporting high doppler
Inventor: HOOLI KARI
IPC: H04L5/02
Filed: 2008-08-12
Abstract: Block spreading generating partial orthogality is applied for the uplink control channel for E-UTRA. For instance, a problem of maximizing the multiplexing capacity leads to numerology causing odd-length sequences which do not have the favorable property of even-length sequences (partial orthogonality). The consequence of this is poor performance in cases of high Doppler effects. Maximal multiplexing capacity is taught without loss of performance at high Doppler by modifying an earlier scheduling request (SR) scheme. The earlier SR multiplexing scheme has a number of parallel SR resources per slot equal to 12*7=84. In one example, the spreading factor of block spreading is changed to an even number, e.g., from 7 to 6. This enables usage of the partial orthogonality properties of CAZAC sequences and as a result inter-code interference in the case of high Doppler is reduced. Other ways to generate partial orthogonality are shown with similar results.
