摘要： An arbitrary number of signaling beacons are synchronized simultaneously and automatically by a received modulated control signal in accordance with an arbitrary communication protocol over a communication link which may be separate from or superimposed upon a perceptible signal periodically provided from signaling beacons. The periodic perceptible signal may be stabilized using a crystal oscillator or an external transmitted signal such as a global positioning system (GPS) signal and synchronization thus maintained for extended periods of time even when the synchronization communication link is not available. Interference is substantially prevented by the communication protocol while supporting the provision of any desired beacon control functions.

摘要： The present invention comprises a device which may be attached to a cable ground block (62) such that the level and type for signal emitted through the upstream flow of the signal, from a residence or business (59), may be determined along with the location of the source of ingress of any such signals. The invention, further includes a device (10) to transmit a signal of predetermined frequency towards a residence, such the source of errant signal ingress may be determined. Further, a method of causing the transmission of the signal at a predetermined time, measurement of the signal and determination of the source of the ingress of the signal is provided.

摘要： A status monitor for coaxial cable networks. The monitor is designed to be directly attached to an output port of an amplifier/repeater in the network and is used as an aid in trouble shooting faults in the network. The monitor comprises a detector (12 or 40) which generates a d.c. voltage indicative of the level of a pilot frequency signal on the network. This d.c. voltage is supplied to a plurality of voltage comparators (18, 20 and 22) which compare the d.c. voltage with different reference voltages in order to sense different fault conditions. If a fault condition is sensed, the outputs of the comparators are used by a tone selection logic (24) and an OR logic switch (26) to control a voltage controlled oscillator (30) to generate a modulating tone. A signal from a crystal controlled oscillator (32 or 48) or IF output of the detector (40) is modulated by the tone produced by the voltage controlled oscillator and radiated. This tone modulated radiated signal may then be used by a technician in field to detect both the location and the nature of the sensed fault in the network.
