Abstract: A system is provided that uses small carrier vehicles that operate along electrified guideways and use standardized connections to automatically carry load-carriers to desired destinations. The load-carriers may be passenger cabins, freight loads or automobile platforms and in each case are loaded and unloaded at separate loading and loading regions. Loading regions are preceded by queue portions of branch paths and may include a group of regions which may be a series of cabin loading regions along a branch path or may be automobile loading regions in side-by-side lanes. Passenger station arrangements are provided for rapid and efficient movement of passengers and for transfer operations when desired. Platform constructions and loading arrangements are provided for rapid loading and unloading and safe transport of automobiles.

Abstract: A system is provided that uses small carrier vehicles that operate along electrified guideways and use standardized connections to automatically carry passenger cabins, freight loads and automobile platforms to desired destinations. Front and rear bogies of the vehicles pivot about front and rear vertical turn axes and carry direction control wheels that cooperate with guide ribs along tracks for selective control of movement to either of two exits from a Y junction. Electric power which can be three phase AC power can be supplied through upper and lower track structures. The upper track structures can define the guide ribs.

Front and rear bogies of the vehicles pivot about front and rear vertical turn axes and carry direction control wheels that cooperate with guide ribs along tracks for selective control of movement to either of two exits from a Y junction. Electric power can be supplied through upper and lower track structures which can be of laminated construction. The guideway provides a protected environment for error-free data transmissions made through closely spaced inductive couplings between monitoring and control circuits along the guideway and control circuits of the carrier vehicles. Control circuitry is provided to obtain highly reliable control of vehicle speed and of starting, stopping and merge operations.

Abstract: A system is provided that uses small carrier vehicles that operate along electrified guideways and use standardized connections to automatically carry passenger cabins, freight loads and automobile platforms to desired destinations. The connections may include electrical connections for power and communication and they are made to upper ends of posts that extend from front and rear portions of each carrier vehicle and up through a narrow centrally located slot in the guideway. Transfer vehicles operate to transfer loads between the carrier vehicles and storage positions and may be controlled to move in either of two transverse directions or to rotate in a turntable operation. Control circuitry is provided to obtain highly reliable control of vehicle speed and of starting, stopping and merge operations.

Abstract: In a one embodiment of a spread spectrum communication system, an unmodulated synchronization wavetrain and one or more modulated intelligence wavetrains are generated in timed relation and are concurrently propagated but separately detected in a receiver. In another embodiment, wavetrains are modulated by opposite phases of an intelligence signal and so detected in a receiver as to produce a synchronization control signal and an intelligence signal by summing and comparing two received signals. Under microprocessor control, the phase of operation of the sequence generators of the receiver is adjusted to obtain phase and frequency information for effecting phase control for synchronization and also to controllably swallow cycles and accurately adjust the effective frequency of the clock signal.
