A dispensing cover for use with a fiberboard drum having a rolled-in lip which defines a cover-receiving opening includes a main body having a first portion and a second portion which is pivotal with respect to the first portion and which is joined thereto using a living hinge. An inner and outer skirt extends about the periphery of the main body, which skirts are spaced apart from each other to define therebetween a cavity for receiving the rolled-in lip of the fiberboard drum. Molded into the outer skirt at the living hinge is a tear strip. Unless removed, the tear strip prevents the second portion from pivoting with respect to the first portion. Barbs formed on the inner or outer skirts and extending into the cavity defined between them engage the rolled-in lip of the fiberboard drum to secure the dispensing cover to the fiberboard drum at least over the non-pivoting first portion.

A cap dispenses material from a container having a mouth. The cap has a main body mountable on the mouth. The main body includes a protruding portion having an opening for receiving material moving through the mouth. A combination seal and dispensing spout is pivotally mounted to the main body and has a top wall with an extended portion. The spout may be pivoted on the main body between a sealing position and a dispensing position. In the sealing position, the spout blocks flow of material through the opening. In the dispensing position, the spout is aligned with the opening in the protruding portion to allow material to flow through the protruding portion and onto the spout so that the material may be dispensed.

A method for generating a preamble of a frame for a multiple input multiple output (MIMO) wireless communication begins by, for each transmit antenna, generating a carrier detect field. The method continues by, for a first grouping of the transmit antennas, generating a first guard interval, and at least one channel sounding field. Continuing, the method applies cyclical shift prior to transmission via the first grouping of the transmit antennas. When the MIMO wireless communication includes more than the first grouping of the transmit antennas, for another grouping of the transmit antennas. For the another grouping of the transmit antennas, generating at least one other channel sounding field. The method proceeds by generating the first guard interval prior to the at least one other channel sounding field, and applying another cyclical shift prior to transmission via the another grouping of the transmit antennas.

A mobile network comprises remote base transceiver station (BTS) nodes (3, 4) linked with a central base station controller (BSC) node (9). The latter is in turn linked with a mobile switching center (MSC, 10), a visitor location register (VLR, 11), and a home location register (HLR, 8). Mobile stations (2, MS-A, MS-B, and MS-C) are located in the cells of the BTSs (3, 4). The remote nodes (3, 4, 3(a), 4(a)) are connected to the central node BSC (9) over a remote backhaul satellite connection. Calls are routed locally while the central nodes continue to manage calls and services from central feature-rich and typically more reliable switches of a core network. This means that calls set up between subscribers on the same remote node get connected within the remote node but call supervision is still carried out by the central nodes. The features and services of the existing core network are preserved. For example, if the calling subscriber is a pre-paid GSM subscriber and their account runs out during the call a release signal will still be sent from the central node to the remote even though the voice traffic is being handled by the remote node.

A method for multiple input multiple output wireless communication begins by determining protocols of wireless communication devices within a proximal region. The method continues by determining whether the protocols of the wireless communication devices within the proximal region are of a like protocol. The method continues by determining the number of transmit antennas. The method continues, when the protocols of the wireless communication devices within the proximal region are of the like protocol, formatting a preamble of a frame of the wireless communication utilizing at least one of cyclic shifting of symbols, cyclic shifting of tones, sparse tone allocation, and sparse symbol allocation based on the number of transmit antennas.
摘要:
The present invention is directed to systems and methods for reducing the distortion of power amplifiers. In particular, methods and systems are described that enable a determination of a pre-distortion correction signal to be determined, which when added to the nominal signal, a reduction in the distortion of the power amplifier results. In addition, methods and systems are described that enable calibration of individual power amplifiers to be accomplished for use with the above described approach. More specifically, the methods and systems are described for use in a MIMO application. These approaches may be applied to on-chip power amplifiers, off-chip power amplifiers, or any combination thereof.
