Abstract: Disclosed herein are techniques and systems to guide a visually impaired user through an urban area, such as, across a crosswalk. A mobile device may receive messages broadcast by wireless beacons deployed in an area and determine a path, for example, across a crosswalk, based on the messages. The mobile device can then provide feedback to guide a visually impaired user across the crosswalk.

Abstract: Systems and methods are described herein for managing the group owner assignments for a peer-to-peer wireless network. The peer-to-peer wireless network may include a group owner that acts as access point for the remaining group members. The group owner generates a succession plan to transfer the group owner role to one of the group members if the group owner departs the peer-to-peer wireless network, either voluntarily or involuntarily.

Abstract: A Packet Processor for a communication apparatus, for processing received and transmitted data streams made of packets. Each packet includes a header and a payload section, which includes a receiving part, a transmitting part, a Backbone Bus for conveying management data, instructions and addresses between various components of the Packet Processor, and a timing and control unit for administering the operation of the Packet Processor, and for timing of using transmission slots for the transmit path. The receiving part includes a receiving PHY interface by which a flow of data stream is conveyed from a Modulator-Demodulator section of the modem to the Packet Processor. The receiving part further includes a receiving Tubular Bus which received the flow of data stream, conveyed from the modem to the Packet Processor, the receiving Tubular Bus conveys data, while processed, the direction from the receiving PHY interface to a host interface.
