Abstract: Methods and systems for treatment of organic waste by means of hydrothermal carbonization include a mixing tank for receiving organic waste. A first batch of mixed wet waste is fed from the mixing tank to a first thermal reactor to undergo thermal hydrolysis. A second batch of mixed wet waste is fed from the mixing tank to a second thermal reactor to undergo thermal hydrolysis. Bio-char sludge is fed in an alternating manner from the first and second thermal reactors to a bio-char cooler. To save energy, hot and pressurized water from the first thermal reactor is subsequently supplied to the second thermal reactor or from the second thermal reactor to the first thermal reactor in an alternating manner for the respective hydrolysis processes.

Abstract: The present invention provides a new and unique method and apparatus for communicating information between two nodes, points or terminals in a wireless local area network (WLAN), where a variable multicast and/or broadcast listening interval and associated signalling is allowed between the two nodes, points or terminals in the wireless LAN network. The two nodes, points or terminals include an access point (AP) or other suitable network node or terminal and a station (STA) or other suitable network node or terminal in the WLAN. The AP and the STA can indicate its capability to support a flexible multicast and broadcast listening interval by using new fields in Beacon and Probe Response frames and in (Re)Association Request Frames. The multicast and broadcast service is setup by using Multicast and Broadcast Service Setup signalling.

Abstract: The invention relates to a mechanism for using services provided by a network in an environment including user-operated short-range wireless terminals and short-range wireless peripheral devices, such as wireless storage units, controllable by the user-operated terminals. A wireless peripheral device is informed that a network providing services is to be accessed, as a result of which the wireless peripheral device accesses the said network. A service is then selected from the infrastructure network by the user-operated terminal, while also indicating that the party requesting the selected service is the peripheral device. The selected service is delivered to the wireless peripheral device through the infrastructure network.

Abstract: Various embodiments are described relating to determining delivery intervals in a wireless network, such as an 802.11 infrastructure network. In an example embodiment, a first negotiated delivery interval for a first wireless node may be negotiated by a transmitting wireless node in a wireless network based on a multicast service setup operation and a Delivery Traffic Indication Map (DTIM) interval. Information may be sent from the transmitting wireless node to the first wireless node based on the first negotiated delivery interval. According to an example embodiment, the first negotiated delivery interval may include an integer multiple number of DTIM intervals.

Abstract: A wireless device transmits beacon packets at periodically occurring time intervals across a wireless channel. When the wireless communications device has not formed a piconet with one or more remote devices, the device scans the wireless channel for a predetermined amount of time immediately following each of the periodically occurring time intervals. During this time a remote device may respond to the beacon packet.

Abstract: The present invention concerns a method of configuring quality parameters in a packet-based transmission flow for packets within the flow, and still further a method of transmitting packet-based transmission flows comprising packets of configured quality classes within a session capable of handling at least two distinguishable flows, the method comprising the steps of: receiving packets of a first flow as a first flow of the session, analyzing the received packets in terms of the configured quality classes, separating those segments of the packets of a configured quality class, which configured quality class differs from a quality class of said first flow of the session. Also, a corresponding reception method is disclosed, and respective transmitter and receiver devices are disclosed.

Abstract: The invention relates to a method for broadcasting beacon frames in a short-range wireless ad-hoc network including a plurality of wireless terminals. In order to improve the efficiency of the ad-hoc network in terms of power consumption, the terminal that defines the beacon interval for the network starts as a beacon broadcaster and introduces an identifier list in at least some of the beacon frames broadcast in the network. The identifier list, which includes identifiers of the wireless terminals belonging to the network, is utilized if another wireless terminal is to be selected as the beacon broadcaster.

The wireless short-range communication network may take the form of a wireless local area network (WLAN), wireless fidelity network (Wi-Fi), an ultra wideband network (UWB) or other suitable network using beacon-based communications protocols either now known or later developed in the future.

Abstract: Various embodiments are disclosed relating to techniques for protecting transmissions in a wireless network. According to an example embodiment, it may be determined at a wireless node whether the wireless node is exchanging transmissions with a plurality of wireless devices associated with a plurality of different signal types in a wireless network. An extended protection request may be sent from the wireless node to a first transmitting device to defer transmission of information for the wireless node for a requested deferral duration. The first transmitting device may defer transmission of information for the wireless node during a deferral period corresponding to the requested deferral duration in response to the extended protection request.
