    摘要： A brevity signaling module for a digital television (DTV) receiver enables the reception of emergency broadcast messages. The overlay signal received at the receiver front end is squared in a squaring loop, producing spectral lines at DC and twice the overlay signal frequency, or 2&ohgr;, where &ohgr;=2&pgr;f and f is the center frequency of the overlay signal. The squared signal is passed through a narrow band filter having a bandwidth sufficient to pass a spectrum containing a plurality of tones 2&ohgr;, 2&ohgr;1, 2&ohgr;2, . . . , 2&ohgr;n, where 2&ohgr;1, 22, . . . , 2&ohgr;n are different frequency tones assigned to different auxiliary functions. The detected tone is used by a control module to determine whether normal multipath processing should be performed or whether this processing should be suppressed and auxiliary functions performed, including turning on the DTV receiver power in order that an emergency broadcast message might be conveyed to persons in the vicinity of the DTV receiver.

    摘要： A digital television (DTV) receiver is provided with a sounder comprising a wideband transmitter and a plurality of wideband receivers having separately located receiving antennas, so that the sounder is, in effect, a bistatic radar system for any given channel, in order to characterize a significant nearby, indoor reflector. A microprocessor receives the timing information generated by the wideband transmitter impulses and the reflected impulse returns to each of the receiving antennas, and calculates a multipath model representing the three-dimensional location of a significant, nearby scatterer.

    摘要： A communication method reduces both the asset energy requirements and communication channel occupancy in a reduced order GPS asset tracking system. The asset is provided with an indication of its position so as to allow detection of substantial movement of the asset at the asset. Reduced order GPS data derived at the asset, such as a railcar, is compressed to allow for shorter railcar data transmission times. This, in turn, reduces both the transmitter energy requirements and communication-channel occupancy, while allowing substantial railcar position changes to be conveniently detected at the railcar. This capability can be used to save further substantial railcar energy by, for example, reporting to the central station less frequently when the railcar position is unchanging.

    摘要： A redundant sensor system for predicting railway hazards including breaks in each rail, the location of the breaks, and determining when a railway vehicle has a flat wheel. Vibration sensors are distributed along both rails of a railway. Each sensor has a detection band at least within the sensing range of adjacent sensors and it is positioned such that the sensor detects vibration in both the horizontal and vertical axis of the rail. A central processor evaluates the data from these sensors and identifies the rail break, the location of the break, and the flat wheel.
