Abstract: A wireless communications network generating device comprises an antenna for transmitting and receiving radio frequency signals, a communications bus for routing data signals; a radio frequency transceiver operable to receive incoming signals from said antenna and supply outgoing signals thereto. The signal processor includes a port electrically connected to the communications bus for receiving data signals. The device further comprises an Ethernet controller having a first port connected to said bus for transmitting and receiving data thereon and a second port for transmitting and receiving data to and from a peripheral device; and a microprocessor for processing said data.

Abstract: A wheel spacer having a boundary wall being substantially rectangular in shape. The boundary wall is defined by first and second longitudinal walls and first and second latitudinal walls. Extending between the longitudinal walls are a plurality of load bearing members having a chamfered top and bottom surface. The load bearing members are spaced in cooperating pairs each providing a space for a row of wheels. Extending between cooperating pairs of load bearing members are load bearing cross-members and extending between non-cooperating pairs of load bearing members are connecting support members.
