摘要： A system and method for detecting the presence or absence of cars, locomotives, or obstructions which may occupy a particular section of track of a model railroad. Digital Command Control signals are used to provide the excitation voltage needed to perform a measurement of the capacitance of an unoccupied section of track. Deviations from this unoccupied capacitance are then measured to indicate occupancy.

摘要： The invention is an electric reusable paper sheet that uses a pattern of conductive charge-retaining islands on the outward-facing side of the first of two thin layers used to encapsulate a Electric reusable paper substrate which interact with conductive areas in the encapsulating sheet. The second encapsulating layer may also coated with a conductive material, or made of a conductive material, and may or may not be patterned. The Electric reusable paper substrate and two encapsulating layers comprise a sheet of Gyricon electric reusable paper on which images can be written and erased repeatedly. The patterned charge-retaining islands of the first encapsulating layer receive electric charges from an external charge-transfer device. After the charge-transfer device is removed, the conductive, charge-retaining islands hold electric charge, creating an electric field in the electric reusable paper sufficient to cause an image change.

摘要： A bichromal ball includes a first hemisphere. The first hemisphere includes a first pigment having a first color and a first polarity. The first pigment is added to a carrier fluid and polymer mixture during formation of the bichromal ball. A second hemisphere includes a second pigment having a second color and a second polarity. The second pigment is added to the carrier fluid and polymer mixture during formation of the bichromal ball. The carrier fluid and polymer mixture have a lower viscosity than the polymer alone. The carrier fluid is substantially removed after the first and second hemispheres are formed. The polymer is left along with the first and second pigments which form the bichromal ball. A diameter of the bichromal ball is reduced after the carrier fluid is substantially removed.

摘要： A receiver for a direct sequence spread-spectrum communication system of the type in which a transmitter mixes a clocked pseudo-random sequence with a modulated carrier for spreading the carrier energy across a wide band of frequencies, comprises a resident clock-driven pseudo-random code generator for locally generating an essentially identical, spectrum despreading code sequence; means for clocking the resident code generator at a nominal frequency which is offset in a predetermined sense from the clock frequency of the transmitted code sequence such that the phase of the locally generated code sequence tends to slide in one direction with respect to the phase of the transmitted code sequence; detection means for determining whether the locally generated and the transmitted code sequence are phase aligned or misaligned and for sensing their actual, incipient and/or predicted departures from a phase aligned state, and phase control means for adjusting the clock frequency for the resident code generator whenever such a departure is sensed, thereby shifting the phase of the locally generated code sequence in the opposite direction with respect to the transmitted code sequence by an amount which tends to restore the two code sequences to a phase aligned state.

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： Instead of normalizing time reference of independent spatially-located clocks using a reference tag transmission from known location, the present invention uses an interarrival time interval between a pulse pair of UWB pulses as a timing metric. Thus, a method of synchronizing spatially-located clocks or normalizing time indications thereof comprises transmitting a UWB pulse pair, determining at first and second monitoring stations a respective count value indicative of a locally measured time interval between received pulse pairs, determining a ratio between clock counts of first and second monitoring stations, and utilizing the ratio to determine clock skew, e.g., a timing correction to be applied to respective local clocks of the monitoring stations. A corresponding system comprises a reference tag transmitter that transmits a pulse pair of UWB pulses to define a time reference interval, a first independent receiver that receives, the pulse pair to generate a first count value indicative an interarrival interval between the pulse pair, a second independent receiver that receives the pulse pair to similarly generate a second count value, and a processor hub responsive to the count values to determine a ratio corresponding to the ratio of respective clock frequencies of the first and second receiver clocks. Once the correction is applied, time-of-arrival information from object tag transmissions may be used to determine object location with sub-foot position accuracies.
