Patent number: 7280520Abstract: A method of operating multiple virtual wireless networks using a common distribution system. Multiple radio frequency side networks are attached to multiple wired networks through a single access point. In this way messages may be sent between a mobile unit and a local area network. The mobile units and the local area networks are associated with identifiers which are used to route a sent message. The messages are sent from a mobile unit to a corresponding access point, which compares the identifier of the mobile unit with stored identifiers in its memory and assigns tags to the messages according to the intended local area network. The tagged messages are then sent from the access point to the distribution system that routes the message to the corresponding portal and to the local area network.Type: GrantFiled: February 6, 2004Date of Patent: October 9, 2007Assignee: Symbol Technologies, Inc.Inventors: Graham David Melville, Richard Montgomery, Ray Martino

Patent number: 7280836Abstract: A computing arrangement may include a first radio transceiver operating in accordance with a first communication protocol using a frequency band and a second radio transceiver operating in accordance with a second communication protocol using the frequency band. An access point operates in accordance with the first communication protocol and transmits a communication signal that has a frame including a first time interval indicative of when communications using the first communication protocol via the frequency band are permitted to the computing arrangement. The computing arrangement determines if the frame includes a second time interval, which is indicative of and is reserved for exclusive communications in accordance with the second communication protocol. If the second time interval is absent from the frame, the computing arrangement inserts the second time interval into the frame. The computing arrangement communicates with a further device only during the second time interval.Type: GrantFiled: April 30, 2004Date of Patent: October 9, 2007Assignee: Symbol Technologies, Inc.Inventors: James R.

Patent number: 7274718Abstract: A method and apparatus are provided to modulate a beam of laser light. An acousto-optic modulator (AOM) is positioned to receive continuous-wave (CW) laser light at an angle approximating the Bragg angle. Fine tuning of the modulation is then used to compensate for any variations in the actual angle from the Bragg angle. A photodiode provides a feedback signal that may be used to tune or adjust the operation of the AOM. The photodiode is positioned to receive laser light at the first order diffraction and provide a signal indicative of the magnitude of the first order diffraction laser light produced by the AOM.
