Abstract: PROBLEM TO BE SOLVED: To provide an interface between a radio LAN and a gateway by detecting a message to be transmitted by a first mobile unit, discriminating, determining whether a route for other mobile unit is determined in the message or it is transferred to other channel and a route for other type of communication station is determined in the message and connecting the gateway with an access point. SOLUTION: A function to transmit and receive a data frame by a proper format, to transmit the data frame from a transmitter/receive 52 at proper time or to make the transmitter/receiver 52 receive the data frame is executed by a medium access control MAC processor 54. The processor 54 is connected with a memory 58 to buffer a data packet. The memory 58 is connected with a switch to perform a processing and switching to determine the route of the data packet, namely, a processor and a multiplexer/demultiplexer 60. A signal received from a cable is received by a cable modem receiver 90 to transfer information to the multiplexer/demultiplexer 92.

Abstract: A portable scanning head emits and receives light from a light-emitting diode (10) to read symbols, such as bar-code symbols. The optics (12,18) within the scanner are operative for focusing a light beam (11) and the view of a light sensor (17) in different planes (13,22) exteriorly of a scanner housing. Imaging means are provided in the unit for imaging a viewing window. The viewing window has an area smaller than that of the scan spot. The system can employ an LED (10) as a light source and tolerate the relatively large-sized (on the order of millimeters) scan spot without sacrificing reading performance since the photodiode (17) "sees" only that portion of the scan spot visible through the viewing window.
