  • Patent number: 4926171
    Abstract: Apparatus for avoiding collision between a vehicle and an object that moves in a trajectory relative to the vehicle. The apparatus includes at least one microwave pulsed transmitter and receiver for transmitting a scanning beam of pulsed energy which scans a sector of space, at least forward of the vehicle, a check for producing timing pulses, a ranging device connected to the clock and the receiver for measuring the time difference between the transmitted pulses and any echoes received by the receiver. The antenna is pivotally coupled to the vehicle and a scanning motor serves to set the antenna in a scanning motion. A direction device is coupled to the scanning antenna for sensing the direction of the antenna. A computer is connected to ranging device, the clock, the direction device and computes continuously the last three coordinated for vector to the object, and is connected to an anunciator which can speak and/or display a message to the vehicle operator.

  • Patent number: 4878050
    Abstract: Motor vehicle control system for enabling persons in an authorized vehicle to control the movements of one or several general vehicles. The system includes a signal beam transmitter at the authorized vehicle, which can be directed in any direction by beam directing apparatus toward a general vehicle having a beam signal receiver attached thereto. Upon receiving the beam, the general vehicle may be stopped, slowed down or stopped after a certain delay. The beam energy may be laser light, microwave, sound energy or any other suitable energy. The beam transmitter may be combined with a video receiver and a video monitor so that the person in the authorized vehicle can view the general vehicle. The beam may be modulated and encoded with messages that can be decoded in the general vehicle.

  • Patent number: 4019027
    Abstract: For the scheduling of activities, particularly construction activities by the Critical Path Method, an apparatus is provided with a mechanical simulation of the network associated with the method, and is adapted to support a network chart of activities and events. It has a progress bar for monitoring such activities and events, which is power driven at a constant rate for indicating the scheduled progress of the entire project at any given time, whereby the scheduler can determine at a glance at the board what adjustments, if any, need be made in the timing and progress of the various activities of the project.
