Abstract: An electric reciprocating motion device includes a motor having a rotary shaft for outputting a reciprocating rotational power and a motion head coupling with the rotary shaft and being driven to move in a reciprocating motion along an axis of the rotary shaft and in a predetermined swing angle range. The motor is a spring motor including a motor unit and a torsion spring having two ends affixing at a motor housing and to the rotary shaft respectively. After the rotary shaft outputs a mechanical torque at one rotational direction, the torsion spring applies a spring force against the rotary shaft to drive the rotary shaft to rotate backward for generating the reciprocating rotational power. Using the spring motor in the electric reciprocating motion device, the device achieves the goals of simple mechanical structure, small volume, easy to install, and low in cost.

Abstract: Time synchronization among nodes in a wireless mobile ad hoc network (MANET) is obtained using a cross layer approach. Each node maintains a routing table that contains entries corresponding to other nodes of the network that are one or more hops away from the node, and topology messages are exchanged periodically among the nodes in order to update their routing tables. A network master node is selected, and remaining nodes that are one or more hops away from the master node are defined as slave nodes. The master node includes master timing information the topology messages that it transmits. The timing information is concatenated to include a first time (T1) at which a topology message was received by the master from each of the slave nodes, and a second time (td) at which the master node transmits a topology message after receiving all the topology messages from the slave nodes.

The fan control module coupled to the board management controller of each of the motherboards receives the motherboard working state signals and generates a plurality of fan control signals accordingly. The fans coupled to the fan control module determine operation according the fan control signals.

Abstract: Communications in a mobile network are scheduled by defining reservation frames having time slots during which network nodes can transmit certain traffic loads while avoiding interference. The nodes maintain maps that identify the slots as either free or reserved based on each node's existing reservations, and reservation information the node receives from neighboring nodes. A node wishing to transmit traffic determines the number of slots required to carry the traffic, selects a first set of slots from among those identified in its maps as free, and transmits a reservation initiation message (RIM) that identifies the first set of slots. Nodes receiving the RIM determine which, if any, of the first set of slots are already reserved based on their own maps, and transmit counter reservation initiation messages (CRIMs) if any slots are reserved. The CRIMs also identify those slots that the CRIM transmitting nodes determine to be currently free.

Abstract: Message or traffic data is transmitted from a given radio or node for reception by one or more other nodes in a communications network, by arranging the node for transmitting the data according to a selected one of a number of different medium access protocols. The medium access protocol selected for a given message or traffic is determined according to one or more of (a) the size of the traffic, (b) the priority of the traffic, (c) the periodicity of the traffic, and (d) whether the traffic is broadcast or unicast to the other nodes in the network. Each radio includes one or more processor and memory modules configured to output messages or traffic for transmission from the radio according to the selected medium access protocol. By using distributed scheduling and traffic control to protect against hidden nodes, the radios can maintain agile portability in tactical urban environments.

Abstract: A method, combination or apparatus for compensating for or predicting the shift in the human perception of colour which occurs when the colour is seen on a small surface area as compared with when it is seen extending over of large surface area. The compensation or prediction is performed by increasing (compensation) or decreasing (prediction) the lightness and chroma of the colour in a specified way. The invention allows choosers of colour to take account of the shifts when making their choice of colours and is useful in choosing colours for paints, plastics, textiles or illuminated surfaces.
