Abstract: Systems and techniques for enhancing accuracy of traffic prediction include a system of one or more computers operable to receive a request relating to traffic prediction, compare a first prediction error for a first (moving average) traffic prediction model with a second prediction error for a second (historical average) traffic prediction model, calculated using a historical data set selected from previously recorded traffic data in accordance with a day and time associated with the request, select use of the first model or the second model based on the comparison of prediction errors, and provide an output for use in traffic prediction, wherein the output comes from applying the first traffic prediction model when the first prediction error is less than the second prediction error, and the output comes from applying the second traffic prediction model when the first prediction error is not less than the second prediction error.

Abstract: An image monitoring apparatus for an elevator includes an image recording section configured to record a sequence of images of an interior of a car photographed by a camera, with a delay between the recording of successive images in the sequence. The apparatus also includes a detecting section configured to detect, based on an image in the sequence of images of the interior of the car, a violent behavior of a passenger in the car, and a display unit arranged in the interior of the car and configured to display the sequence of images of the interior of the car when the violent behavior of the passenger in the car is detected. The image recording section is further configured to reduce the delay between the recording of the successive images in the sequence of images when the violent behavior of the passenger in the car is detected.

Abstract: In an image monitoring apparatus for an elevator, image recording means records an image in a car photographed by a camera, and monitors based on the image in the car whether or not there is a violent behavior of a passenger in the car. The image recording means makes a recording density of the image in the car higher than usual when the violent behavior of the passenger in the car is detected. The operation control means homes the car on a predetermined floor when the violent behavior of the passenger in the car is detected by the image recording means.

Abstract: A method for the allocation of passengers in an elevator group. The group has several elevator lobbies and multi-door elevators. Each passenger gives his/her destination floor by means of a call input device, so that the passenger's starting and destination floors are thereby defined.

Abstract: The invention relates to a method for allocating landing calls issued by passengers, in which method each passenger gives his/her destination floor via a call device. According to the invention, the call is allocated to an elevator car to serve the passenger via genetic allocation, wherein the floors of departure and destination of the passenger are recorded in alternative chromosomes, the required data regarding the passenger and elevator car being recorded in a gene in the chromosome, that, utilizing genetic methods, the best chromosome is selected, and that the passenger is directed into the elevator car selected, and that the selected elevator car is directed to serve the passenger in question.

Abstract: Method for telemonitoring the condition and state of an elevator and for determining its need for maintenance by performing an automatic test run of the elevator car (1) in the elevator shaft (2) to collect data for use in an elevator telemonitoring process. The method of the present invention is characterized in that the aforesaid test run comprises a number of automatic test run cycles synchronized with respect to each other.

Abstract: Genetic procedure for the allocation of calls issued via the landing call devices of elevators included in a multi-deck elevator group, in which procedure a multi-deck elevator model is formed in which the limitations of and rules of behaviour for each elevator in the multideck elevator group and each car of each elevator are defined; a plurality of allocation options, i.e. chromosomes are formed, each of which contains a car data item and an elevator direction data item for each active landing call, and these data, i.e.

Abstract: A method of and apparatus for providing self-learning correction to the error in positioning movement of a platform in a vehicular wheelchair lift or any moving member of machinery or an equipment. The method includes the steps of programming the platform or moving member to stop at a target position, calculating an error between the programmed target position and an actual stop position of the platform or moving member, and deriving a new target position to stop the platform or moving member based on the calculated error to compensate the overshoot or shortcoming of the actual stop position of the platform or moving member. The apparatus implementing this method may include a programmable control mechanism such as a microprocessor having means for performing the programmed sequential operations.

Abstract: The present invention relates to servicing a car to a hall call in a group management system which controls a plurality of elevators installed in a building. A group management control method for an elevator according to the present invention is capable of decreasing an average waiting time and a waiting generation probability by selecting more than two cars having high evaluation values after evaluating each car using a synthetic evaluation function, and allocating one car which is regarded as an optimum car for servicing by applying a genetic algorithm which is known to be highly efficient in a system with a large search space.

Abstract: A procedure for allocating the calls entered via landing call devices of the elevators in an elevator bank forms several allocation options. Each allocating option contains, for each active landing call, a call data item and an elevator data item which together are used to determine which elevator should service the call. The value of a cost function is calculated for each allocation option; one or more of the allocation options is repeatedly changed with respect to at least one data item, and the values of the cost functions of the new allocation options are calculated. Based on the values of the cost functions, the best allocation option is selected and the active elevator calls are allocated to the elevators in the elevator bank accordingly.
