Abstract: This invention relates to an integrated drive generator of the type employed onboard aircraft for power generation and prime mover starting. Prior art integrated drive generators which provided for a prime mover starting mode drove a prime mover through a constant speed transmission in order to provide motive power to the engine. The present invention provides a power path for prime mover starting which couples the motor/generator directly to the prime mover and decouples the motor/generator from the transmission by means of properly oriented one-way clutches.

Abstract: A procedure for damping the vibrations of an elevator car or part supported by elastic suspension elements comprises the steps of measuring the acceleration of the elevator car or part by means of at least one acceleration transducer, using the output signal from that transducer to control at least one vibration damper, which, in order to damp a vibration, imparts to the elevator car or part a force acting in a direction opposite to the direction of the vibration and substantially simultaneous with it. An apparatus to carry out the procedure is also disclosed.

Abstract: An elevator car and a counterweight is suspended on a sheave by means of a rope in a well-rope faashion. In dependence on the number of passengers on the car, the sheave is applied with an unbalance torque making appearance between the car and counterweight. Upon starting of the elevator operation by releasing a brake, upward or backward bouncing of the car takes place due to the unbalance torque. For preventing such bouncing of the car, a start compensation is performed by generating a motor torque which can cancel out the unbalance torque in precedence to the releasing of the brake. The brake is installed swingably on a winding equipment. Displacement of the brake during actuation thereof indicates the presence of the unbalance torque.

Abstract: An elevator system employing a micro-processor-based group controller (FIG. 2) communicating with the cars (3, 4) to assign cars to hall calls based on a Relative System Response (RSR) approach. However, rather than using unvarying bonuses and penalties, the assigned bonuses and penalties are varied using "artificial intellience" techniques based on combined historic and real time traffic predictions to predict the number of people behind a hall call, and, calculating and using the average boarding and de-boarding rates at "en route" stops, and the expected car load at the hall call floor. Prediction of the number of people waiting behind hall calls for a few minute intervals are made using traffic levels measured during the past few time intervals on that day as real time predictors, using a linear exponential smoothing model, and traffic levels measured during similar time intervals on previous similar days as historic traffic predictors, using a single exponential smoothing model.

Abstract: An elevator control system employing a micro-processor-based group controller (FIG. 2), which communicates with the cars (3, 4) of the system to determine the conditions of the cars, and responds to hall calls registered at a plurality of landings in the building serviced by the cars under control of the group controller, assigning hall calls to cars based on the summation for each car, relative to each call, a weighted summation of a plurality of system response factors, some indicative, and some not, of conditions of the car irrespective of the call being assigned, assigning varying "bonuses" and "penalties" to them in the weighted summation. "Artificial intelligence" techniques are used to predict traffic levels and any crowd build up at various floors to better assign one or more cars to the "crowd" predicted floors, either parking them there, if they were empty, or more appropriately assigning car(s) to the hall calls.

Abstract: In a group of elevators with double cars, the assignment of such double cars to floor calls takes place at scanner positions .alpha. in two procedural steps, according to two parameters: primarily by assignment of the individual cars of all double cars by logical decision, according to a criteria chain (KK), and subsidiarily by assignment of the double cars according to the minimal loss time of all involved passengers. The individual elevators each have a microcomputer system with a calculating device and are connected with each other by way of a comparator circuit to form a group control. The optimal individual cars are assigned for each elevator by floor in the associated individual car/call assignment memories. The optimal double car is selected by comparison of the loss times of all elevators calculated as the total operating costs K.sub.g (.alpha.) and is assigned to the respective floor in the associated double car/call assignment memory. For the total servicing costs K.sub.g (.alpha.

Abstract: An elevator group control assigns a floor call, which is to be assigned to a car for the first time, immediately and finally after its input. The operating costs corresponding to the waiting times of passengers are computed merely for the input floor and the destination floor of the new call from data specific to each of the elevators and these costs are transferred into a cost register for all the elevators immediately after the input of the call. Thereafter, the comparison of these operating costs takes place at once, wherein the call is finally assigned to the elevator with the smallest operating costs. The operating costs computation extends over all traffic participants situated in the cars and at the floors, wherein the computer utilizes a traveling time table, in which the traveling times between each floor and every other floor are stored.

Abstract: The invention relates to call registration wherein of a plurality of elevators an elevator which a user (passenger) wants to ride is called to the elevator hall of the user. A display is provided at an elevator hall for users. When a user depresses a hall calling button, a group supervisory controller determines and selects a suitable elevator, and causes the condition of the elevator to be displayed on the display in the form of sentences or the like. If the user is satisfied with the selected elevator, the hall calling button is not actuated again. If the user is dissatisfied with the selected elevator, the hall calling button is depressed again so that the controller selects another elevator for service to the user.
