Abstract: A wireless LAN environment includes at least one access point that supports a number of wireless communications devices which are configured to operate in the U-APSD mode. The transmission of packets by an access point to a wireless communications device operating in the U-APDS mode can be accomplished in an efficient manner by coordinating the unscheduled service periods of the wireless communication devices. The service periods are placed into a tightly packed list ordered according to a network address associated with each wireless communications device.

Abstract: A golf club shaft protector is disclosed as including an elongated hollow plastic tube having a polygonal cross-sectional configuration with an unequal number of sides interconnected to each other by corner sections. Each of the unequal number of sides have the same predetermined length and each of the corner sections have the same predetermined angular shape. One of each of the corner sections faces one of each of the sides. Preferably, the unequal number of sides is at least seven to provide the largest possible opening with the greatest amount of rigidity for receiving the golf club shaft, including a golf club handle. The golf club shaft protector also includes a tubular element mounted adjacent the open upper end of the hollow plastic tube and includes an outer wall section, an inner wall section and flexible lip sections.

Abstract: A one-piece tube multi-pack and its method of manufacture are disclosed. The one-piece tube multi-pack includes an elongated thin-walled tubular element made of transparent flexible plastic material with inner and outer peripherally extending walls. At least one thin-walled web section is integrally connected to the inner peripheral extending wall of the tubular element and has greater flexibility than the tubular element in order to adjustably accommodate a plurality of separate discrete products positioned on opposite sides of the at least one integral web section. The at least one integral thin-walled web section may be connected to the inner peripherally extending wall of the tubular element at different relative locations, for example, in a spiral or curvilinear or other shaped path throughout the tubular element.

Abstract: A user friendly dumbbell that is comfortable, safe and durable, and which also protects against damage to surfaces against which the dumbbell may come into contact is disclosed. The dumbbell is typically provided with an elongated shaft and enlarged members attached to opposite free ends of the elongated shaft. Surrounding protective and durable coverings are provided for the elongated shaft and enlarged members that is both user friendly during use, while also protecting supporting and other surfaces against damage when the dumbbell is not in use. The protective and durable covering along the elongated shaft includes a resilient and compressible element having at least one porous high density foam rubber covering.
