A packet alignment system for pre-processingaligning incoming packets may comprise one or more registers for receiving control signals and data signals. A method on a wireless communication device may include tuning to a first subchannel based on a schedule received from an access point the schedule to indicate that the HEW device is assigned to the first subchannel. Transistors that are not part of the signal path through the multiplexer are deactivated, wherein a series of two or more deactivated transistors have significantly less sub-threshold leakage current than a single deactivated transistor. Alternatively, the door may be located on top of the arm and a periscope configuration is used to project the image upwardly and then horizontally from the arm to be displayed on a surface. The alignment feature can be a post with corresponding recess.
