Abstract: In one aspect, a scrubber brush assembly is provided. The scrubber brush assembly includes a scrubber brush having a body of open-cell foam including an interior surface, a sleeve received in contact with the scrubber brush, the sleeve including peripherally-spaced, longitudinal walls and reinforcing segments interconnecting adjacent ones of the longitudinal walls and forming elongated pockets along the length, the sleeve having raised ribs extending along the length, and a mandrel having recesses formed on an outer surface, the mandrel being coupled to the sleeve by receiving the raised ribs within the recesses. Scrubber brush subassemblies, high stiffness mandrels, and methods of assembly are provided, as are numerous other aspects.

Abstract: A method for reducing the peak-to-average power ratio (PAPR) in an OFDM based wireless system is disclosed herein. The reduced PAPR may be achieved by appropriately selecting subpackets for transmission. For example, a scheduler may elect to sequentially transmit the subpackets in an order related to the PAPR of each of the subpackets until at least one of the subpackets is properly received. In one embodiment of the instant invention the order of transmission is selected to be from lowest to highest PAPR.

Abstract: A method that employs aspects of CDMA and OFDM modulation for controlling transmissions between a mobile station and a base station is provided. The method comprises forming a frame having a plurality of slots therein and then using CDMA modulation in a first portion of the plurality of slots, and using OFDM modulation in a second portion of the plurality of slots.

Abstract: A wireless communication system and method provide air interface channels using diverse multiframe types on a single frequency carrier. Physical channels for a single frequency carrier are defined as time slots, a series of consecutive time slots define a frame, and a plurality of multiframe types are defined for the single frequency carrier as including different numbers of consecutive frames. By multiplexing a plurality of multiframe types onto a single frequency carrier, diverse channels types such as traffic channels, broadcast control channels, and common control channels can be accommodated on the same frequency carrier to enable efficient utilization of frequency resources. In one exemplary implementation, a first multiframe type is defined as having x consecutive frames, a second multiframe type is defined as having y consecutive frames, and a third multiframe type is defined as having z consecutive frames.
