A “peer-to-peer” hierarchical routing protocol—also referred to as Zone-based Hierarchical Link State Routing protocol (or “ZHLS”)—which incorporates location information into a novel “peer-to-peer” hierarchical routing approach. The network may be divided into non-overlapping zones. Aggregating nodes into zones conceals the detail of the network topology. Initially, each node knows its own position and therefore zone ID through a position determination unit, such as a Global Positioning System (GPS). After the network is established, each node knows the low level (node level) topology about node connectivity within its zone and the high level (zone level) topology about zone connectivity of the whole network. A packet may be forwarded by specifying the hierarchical address—zone ID and node ID—of a destination node in the packet header.

A stage apparatus has a stage movable in a first direction and first and second measurement systems measuring a position of the stage in a predetermined direction. The first and second measurement systems each has a laser interferometer and a mirror system including a first reflecting mirror elongated in the first direction. A measurement value is transferred from one measurement system in use to the other measurement system and the measurement system in use is switched between the first and second measurement systems within a overlapping zone where said first and second measurement system can simultaneously measure the position of the stage. In the switch, the measurement value to be transferred is corrected based on a difference in the lengths of the light paths due to a shape of a surface of the first reflecting mirror of the first and second measurement systems.

The lighting device for lighting a lighted field comprises a light source having first and second lighting modules. The lighting modules are adapted to light lighted domains of the lighted field. The lighted domains form an overlap zone, and each lighting module defines an overlap volume. The device includes detector means adapted to detect a zone of reduced lighting in the overlap zone, and control means adapted to increase the light flux from said second lighting module when the detector means detect a zone of reduced lighting. The invention is applicable to lighting devices used in operating theaters.

A telecommunications system and method is disclosed for deliberately producing synchronous timing jitters in order to dynamically shift the delay spread within the overlap zone in a simulcast system. At a synchronous periodic rate, the timing differential between transmission of the signal from the control point to each of the transmitters can be continuously adjusted to continuously change the relative timing between multiple received signals in the overlap zone. Alternatively, the timing adjustments can be performed only upon reception of a retransmission request. In either case, the timing adjustments are performed so as to not be noticed by the mobile subscriber.

The invention discloses a threshold value-based optimized weighted centroid positioning method in a WSN. The method is characterized by comprising two parts, namely beacon node combination optimization and weighted centroid positioning computation; in the first part, unknown nodes select n nearest beacon nodes, each three beacon nodes form a combination, whether a combination meets conditions or not is judged, and beacon nodes meeting conditions are used for weighted centroid computation; in the second part, an overlapping zone is divided into four parts, the ratio of the area of each part to the total area serves as a weight number, and the centroid of each part is subjected to weighted computation so as to obtain coordinates of the unknown nodes. The optimized algorithm reduces positioning error and improves the node positioning accuracy.
