摘要: Approaches for multicast routing a group packet that includes a payload and routing information (e.g., a target identifier vector and a target multicast group ID) in a network having multiple cells each comprising a parent node and one or more child nodes include establishing and storing one or more child-node multicast group map tables associated with the child node(s) for each cell; receiving a multicast group packet; determining whether to forward the multicast group packet to the child node(s) based at least in part on the child-node multicast group map table(s) associated therewith and the received target identifier vector; and if so, causing the parent node to forward the multicast group packet to the child node(s).

摘要: To promote efficient and reliable communication of beacons among neighboring nodes in a wireless network, instead of having each node transmit beacons over its operational channel and switch to a different channel to receive its one-hop neighbors' beacons, nodes may transmit beacons over a different channel (i.e., different from the operational channel) and receive beacons over their operational channels. These outgoing “visitor beacons” may contain the usual beacon information but most importantly specify the operating channel of the transmitting node over which conventional beacons may be transmitted and received.

摘要: An electromagnetic heater for heating an irregularly shaped object, including: a cavity within which an object is to be placed; at least one feed which feeds UHF or microwave energy into the cavity; and a controller that controls one or more characteristics of the cavity or energy to assure that the UHF or microwave energy is deposited uniformly in the object within ±30% over at least 80% of the volume of the object.

摘要: A method of delivering energy to an object in a cavity may include transmitting electromagnetic energy to the cavity at a plurality of frequencies. At each of the plurality of frequencies, the method may also include determining an efficiency of energy transfer into the object and adjusting power transmitted at each of the plurality of frequencies such that a multiplicative product of the efficiency and the power transmitted is substantially constant across each of the plurality of frequencies.

摘要: A method of heating and/or thawing using an RF heater is described. In some cases the heating differentially heats portions according to their dissipation ratios. Optionally, this avoids dissipating large amounts of energy into thawed portions while frozen portions are still extant and heat slowly. Optionally, this prevents overheating of thawed portions.

摘要: An apparatus for applying electromagnetic energy to an object in an energy application zone via at least one radiating element is disclosed. The apparatus may include at least one processor. The at least one processor may be configured to determine a value indicative of energy absorbable by the object at each of a plurality of frequencies and to cause the at least one radiating element to apply energy to the zone in at least a subset of the plurality of frequencies. Energy applied to the zone at each of the subset of frequencies may be a function of the absorbable energy value at each frequency.
