An approach is provided for providing a collaborative reply to a flooding message over an ad-hoc mesh network. A reply message to a flooding message is received by a wireless node within the ad-hoc network. The wireless node monitors for an acknowledgement of receipt of the reply message according to a routing table and initiates a scheduled transmission of the reply message based on the monitoring.

An approach is provided for locating communities over an ad-hoc mesh network. Community identifiers are used to locate communities and community members over an ad-hoc mesh network. The community identifiers are also associated with keys to authenticate members of the community and to protect the privacy and anonymity of information exchanged between the members.

A Nuclear Magnetic Resonance (NMR) apparatus and method for measuring the water content of samples has a device to produce a main magnetic field; a sample receiving space within a main magnetic field; a device to excite a measurable RF magnetization to a sample placed into the sample receiving space at an operating frequency defined by the main magnetic field; a device to measure the RF signal produced by the excited sample; and a device to determine the water content in the sample based on the RF signal. The sample receiving space is capable of accommodating a sample having a volume of at least 0.5 dm, and the device to produce a main magnetic field has a resistive electromagnet which is adapted to produce a main magnetic field corresponding to an operating frequency of 400-2000 kHz.

Apparatuses may stay synchronized with a network via a beacon signal that is transmitted at a set interval. Various communication-related activities may be planned around an instance when a beacon signal is expected, or a target beacon transmission time (TBTT). While some networked apparatuses are active during every TBTT, other apparatuses may operate using a diluted beacon period that is an integer multiple of the network beacon signal interval. Diluted beacon intervals may initiate periods of time during which apparatuses may become 'aware' of other apparatuses. Awareness may comprise information related to communication configuration, apparatus status, and services offered by the various apparatuses in the network. Awareness information obtained during an awake window may also comprise information on data-related tasks that are pending in one or more apparatuses which may allow for the control of further data conveyance activities.

Data-related task support in wireless communication systems

Embodiments of the present invention are directed to facilitating apparatus interaction. In at least one example embodiment of the present invention, apparatuses may comprise both triggered communication activities and automated communication activities. Triggered communication activities may correspond to, for example, user and/or application instigated actions in a wireless apparatus. Automated activities may occur without any requirement for user intervention, and further, without any notification to the user that an action has occurred.

Beaconing mode for wireless communication

An approach is provided for discovering a location-based service over an ad-hoc mesh network. A location-based service is discovered sending an anonymous flooding message including a query over the ad-hoc mesh network. A wireless node replies to the flooding message over the ad-hoc mesh network with a pointer to the discovered location-based service.

Method, apparatus, and computer program product example embodiments enable contention for access to a wireless communications medium. In example embodiments, a method comprises initiating a channel access procedure by an apparatus; performing, by the apparatus, in response to the channel access procedure initiation, a random draw for permission to start contention with other member apparatuses of a group in which the apparatus belongs, the random draw being based on how many member apparatuses of the group are expected to compete for the wireless communications medium; and starting, by the apparatus, contention for access to the wireless communications medium, if the apparatus wins the random draw.

Method, apparatus, and computer program product for contention access in wireless communication

Apparatuses may stay synchronized with a network via a beacon signal transmitted at a set interval. Communication-related activities may be planned around instances when beacon signals are expected, which may also be known as a target beacon transmission time (TBTT). Scanning opportunities, which are periods of time during which apparatuses may perform passive scanning, may be planned based on an interfere multiple of a network beacon signal interval. Apparatuses may, upon realizing a scanning opportunity, opt either to utilize the scanning opportunity or to participate in network beaconing. In example scenarios where apparatuses opt to utilize scanning opportunities, apparatuses may prepare a network information message and then enter a passive scanning mode. Apparatuses may remain in the passive scanning mode for the duration of the scanning opportunity, reacting when messages are received from devices outside of the network by transmitting the network information message.

Network discovery in wireless communication systems

The invention relates to a NMR method for determining moisture content of a sample, in which method a sample is subjected to a magnetic DC-field, the sample under magnetic DC-field is subjected to a sequence of excitation pulses in RF-frequency with pulse interval for exciting hydrogen nuclei, and NMR signal of the excited hydrogen nuclei is measured. In accordance with the invention spin-lattice relaxation time is estimated for the sample, and pulse interval is adjusted longer than the estimated spin-lattice relaxation time.

The invention relates to an electromagnet and a method manufacturing the same. The electromagnet includes a frame having a volume within, and a conductive wiring wound around the frame. In accordance with the invention the magnet includes at least two circular grooves having two walls parallel to the each other and perpendicular to the longitudinal axis of the frame, at least two wire stacks each including at least one substack, wherein the wire has a cross section, at least one of the walls separating the two circular grooves, and jump wiring interconnecting the stacks so that contributions from jump wires of the adjacent stacks to total axial directional current are cancelled in average by the current of the return current wire, such that their contribution to the resulting magnetic field at the sample volume is minimized.
