Abstract: Aspects of the disclosure relate to a packaging system, method of packaging, apparatus, handle structure, an article carrier for packaging a plurality of articles, and to a blank for forming the handle structure or article carrier. The packaging system provides an apparatus for applying the handle structure or article carrier to one or more articles. The apparatus provides a component adapted to engage the blank and form the handle structure or article carrier so as to displace a first side of the handle structure or article carrier, disposed on a first side of an article retention structure to a greater extent than a second side of the handle structure or article carrier, disposed on a second, opposing, side of an article retention structure.

Abstract: The invention described herein is directed to a downhole fluid injection dispersion device. This invention may be employed to radially disperse fluid injected downhole in a well bore. This invention comprises a body comprising an inlet port and at least two radial outlet ports.

Abstract: A contention resolution method includes the steps of determining a contention has occurred and requesting contention resolution from radios in the system (604). Radios in the system receive the request and do not transmit in the next control frame (606). Group leader radios (202, 208 and 214) transmit the identification code they were able to demodulate in the previous frame to the master radio (608). The master radio (212) receives the information from the group leaders and transmits a control-channel access message to one of the contending radios (610).

Abstract: A medium access protocol which adjusts number of contention slots in a variable length frame and superimposes a variable window structure over the frame structure. The number of contention slots (24) in a frame (28, 30) is changed on a frame by frame basis by determining if a collision occurred in any contention slot (44). If not the contention slot is removed (48) and if so, the number of slots is increased (52). In high traffic situations, if the average load is greater than a threshold (107, 120) the number of frames in a window is increased (130). If the load drops below the threshold (120), the number of frames per window is decreased (124).
