Patent number: 7733229Abstract: Ultra wideband (UWB) techniques are applied to radio frequency identification (RFID). For instance, a reader generates a UWB IR interrogation signal, and receives a UWB IR reply signal from an RFID tag in response to the interrogation signal. In addition, the reader may generate from the UWB IR reply signal a baseband response sequence. This sequence includes at least a tag identifier. A reader may store at least a tag identifier. Upon receipt of a UWB IR interrogation signal, the tag obtains a plurality of clock pulses from the UWB IR interrogation signal.

Patent number: 7463886Abstract: A wireless communications device detects a change in its residual energy status, and transmits the residual energy status across a wireless communications network to a remote device that coordinates communications in the wireless communications network. For example, the remote device may be a piconet coordinator (PNC) in an IEEE 802.15.3 network, or a master device in a Bluetooth network. A wireless communications device that coordinates communications in a wireless communications network (the coordinator) transmits one or more first handover commands to one or more remote devices upon the occurrence of a triggering event. Based on responses to these first commands, the coordinator selects a remote device for coordinating future communications in the wireless communications network.Type: GrantFiled: November 12, 2003Date of Patent: December 9, 2008Assignee: Spyder Navigations L.L.C.Inventors: Juha Salokannel, Jukka Reunamäki, Arto Palin, Harald Kaaja, Ulrico Celentano

Patent number: 7454171Abstract: The invention solves the problem of reducing interference in simultaneous wireless LAN (WLAN) and Bluetooth signal handling, especially in voice over IP communications via a WLAN telephone to a Bluetooth headset. The invention sets up a voice link between the terminal and the headset by establishing sniff anchor points in the ACL link for assigning relative priorities to the WLAN and Bluetooth ACL packet traffic. A higher priority is assigned to WLAN packet traffic when it collides with original Bluetooth ACL packet traffic during a sniff anchor point. Thereafter, a higher priority is assigned to the terminal's retransmission of aborted Bluetooth ACL packets and the headset's response ACL packets in available Bluetooth slots following the anchor point.Type: GrantFiled: February 25, 2005Date of Patent: November 18, 2008Assignee: Nokia CorporationInventors: Arto Palin, Mauri Honkanen, Jukka Reunamäki
