摘要： Various methods for determining a configuration of a communications system are provided, including methods for determining system node positions. One example method includes generating a node attribute information segment, and adding the node attribute information segment to an attribute information message at a position within the attribute information message indicative of a position of a node within a series string of communications connections. Some of the methods may be implemented within the context of an asset locating system that analyzes the timing of wireless signals to determine a location of the source of the signal. Related systems and apparatuses are also provided.

摘要： An ultra wideband (UWB) or short-pulse RF system is disclosed that can be used to precisely locate or track objects (such as personnel, equipment, assets, etc.) in real-time in an arbitrarily large, physically connected or disconnected, multipath and/or noisy environment. A system implementation includes multiple zones or groups of receivers that receives RF signals transmitted by one or more timing reference tags and one or more objects having associated object tags. Each zone or group may share a common receiver. By combining a multiple reference tag system with a virtual group of receivers, i.e., a zoning technique or system, a cost-effective system can be provided that offers scalability and flexibility to monitor a significantly expanded coverage area.

摘要： An RF object locating system and method that uses or includes a set of N (N>2) receivers (monitoring stations) located at fixed positions in and/or about a region to be monitored, one or more reference transmitters that transmit a timing reference, a location processor that determines object location based on time-of-arrival measurements, and at least one object having an untethered tag transmitter that transmits RF pulses, which may additionally include object ID or other information. Free-running counters in the monitoring stations, whose phase offsets are determined relative to a reference transmitter, are frequency-locked with a centralized reference clock. Time-of-arrival measurements made at the monitoring stations may be stored and held in a local memory until polled by the location processor. The invention permits rapid acquisition of tag transmissions thereby enabling the monitoring of large numbers of objects, and also provides a unique approach to data correlation in severe multipath environments.

摘要： A method and apparatus for determining the location of an object. An object to be located can be provided with an object locator that includes a display. When the object locator receives a signal indicating that the object associated with the object locator is to be located, the display changes display state to provide a visual indication that the signal has been received. The object locator can be ambient energy-powered, and the display can be a bistable display, such as a rotating element display device.

摘要： A twisting ball display sheet is disclosed which utilizes a mechanism other than Zeta potential to create dipole moment to rotate a plurality of bichromal balls. The twisting ball display sheet comprises a transparent sheet which contains a plurality of bichromal balls. Each bichromal ball comprises two hemisphere. Each hemisphere has a material which has a different work function than the work function of the other hemisphere. The two different work functions of each bichromal ball create a dipole moment which at the presence of a proper electric filed will cause the bichromal ball to rotate.

摘要： An apparatus for fabricating hemispherically bichromal balls, comprising a separator member having opposing first and second surfaces located and an edge region in contact with both surfaces, and delivery means for flowing first and second colored hardenable liquid material over the first and second surfaces, respectively, so that the liquid materials arrive at the edge at substantially the same flow rate and form a reservoir outboard of the edge region. The reservoir comprises side-by-side regions of different colors which do not intermix. Further means is provided for propelling the first and second liquid materials away from the separator member and out of the reservoir into a fluid medium as a plurality of side-by-side bichromal streams whose forward ends become unstable and break up into droplets which form into spherical balls, each of the balls comprising hemispheres of differently colored hardenable liquid, and means for collecting the bichromal balls.
