  • Publication number: 20240101155
    Abstract: A route planner detects a pedestrian from surrounding data representing a situation of surroundings of a vehicle, identifies a position of a pause-by object in the surroundings of the vehicle prompting the pedestrian to pause, creating a travel route over which the vehicle will travel when the pedestrian is detected, assuming the pedestrian will enter a road on which the vehicle will travel when the identified position of the pause-by object is not in the vicinity of the pedestrian, and assuming the pedestrian will not enter the road when the identified position of the pause-by object is in the vicinity of the pedestrian.

  • Patent number: 11919541
    Abstract: Automated drive system comprises a control device. The control device executes run control processing of the automated drive vehicle provided to a driverless transportation service. The run control processing includes carriage porch control processing. The carriage porch control processing is performed when a PUDO position of a user corresponds to a carriage porch of a facility including a zone for run and a zone for PUDO. In the carriage porch control processing, it is judged whether or not there is an empty space in the zone for PUDO. If it is judged that there is no empty space, it is judged whether or not a quick PUDO of the user in the carriage porch is expected. If it is judged that the quick PUDO is expected, a target PUDO position to perform a PUDO action of the automated drive vehicle is set to any position in the zone for run.

  • Patent number: 4658292
    Abstract: An enciphering key distribution system comprises a transmitter having an address generator for generating the addresses of those subscribers to which a first enciphered TV signal is to be distributed. An enciphering generator generates a second enciphering, in response to the individual addresses, on a one-to-one correspondence with the individual subscribers. A multiplier produces a product which is associated with all the subscribers. An adder adds the first enciphered signal to the product. The system also comprises a receiver having a divider for dividing the signal transmitted from the transmitter by one of the second encipherings on a basis which is assigned to the particular subscriber or receiver.

  • Patent number: 4578800
    Abstract: A Viterbi decoder synchronization circuit comprises a phase shifter for introducing a variable amount of delay time to a received bit stream of convolutional codes in response to a control signal applied thereto with respect to a word synchronization signal which is derived from the bit stream. A first detector detects maximum and minimum metric values of the Viterbi decoder. A second detector detects the difference between the detected maximum and minimum metric values for coupling to an integrator. The output of the integrator is applied to a third detector which detects when the integrator output reaches a value indicative of a word-in-sync or word-out-of-sync condition. A phase shift signal is generated in response to an output signal from the third detector and applied to the phase shifter as the control signal.
