摘要： A transportation vehicle alert monitor incorporating a speech synthesizer for voice announcement of vehicle location by stop number. The monitor includes a radio receiver responsive to coded RF signals containing either current vehicle location data or data for programming the monitor. Current location data includes school system number, bus number, route number, and stop number. Programming data includes school system number, monitor serial number, student number, two route numbers for one bus number, and initial and final alert stops for each route. Programability of initial alert stops allows each alert monitor to be remotely adjusted to allow varying conditions including the discharge between adjacent stops, traffic conditions, and distance from a passenger's house to the stop.

摘要： Self-programming scanning receiver having superheterodyne circuitry, microprocessor controlled synthesized frequency tuning circuitry, frequency validation means, a learn mode to invoke the frequency validation means for all frequencies tunable by the tuning circuitry, listen mode for scanning of frequencies learned in the learn mode, and an ignore mode for erasing frequencies from permanent memory. The frequency validation means comprises a detector output connected to a high pass filter input, high pass filter output connected to a noise detector, noise detector output connected to a first A/D converter input, algorithms stored in microprocessor program memory for analyzing A/D samples obtained via first A/D for squelch condition, detector output also supplying the input of a low pass filter, output of low pass filter connected to a second A/D converter input, algorithms for analysis of A/D samples obtained from second A/D to determine sufficiency of modulation level and lack of digital waveforms, electrically alterable permanent memory for storing information identifying voice channels.
