Abstract: Various embodiments of the invention are detection systems and methods for detecting call provenance based on call audio. An exemplary embodiment of the detection system can comprise a characterization unit, a labeling unit, and an identification unit. The characterization unit can extract various characteristics of networks through which a call traversed, based on call audio. The labeling unit can be trained on prior call data and can identify one or more codecs used to encode the call, based on the call audio. The identification unit can utilize the characteristics of traversed networks and the identified codecs, and based on this information, the identification unit can provide a provenance fingerprint for the call. Based on the call provenance fingerprint, the detection system can identify, verify, or provide forensic information about a call audio source.

Abstract: A method and system for effectively identifying an incoming peak traffic situation in an elevator system is provided. To allow faster detection of a peak traffic condition, use is made of both information obtained from traditional peak hour identification and history data obtained from statistics regarding the numbers of passengers. Traditional peak hour identification monitors the car weight and the number of calls in real time. Statistics provide information regarding typical rush hours in the building. In the method of the present invention, the number of passengers gathering on the lobby floor is forecast on the basis of statistics at the moment when the next elevator is at the lobby floor, ready to take in passengers. When the forecast number of passengers exceeds the car load threshold value for traditional peak hour identification, an incoming peak traffic mode can be activated reliably already on the basis of a single peak elevator.

Abstract: The method serves for automatic checking of the availability of technical equipment which is arranged in or at a building and executes at least one repeatable procedure, and comprises the following steps. There is determined at least one estimated value (NS(i,t)) for the frequency of the performance of the procedure for a first time period and/or second estimated value (NS(i,t+?t)) for the frequency of the performance of the procedure for a second time period. A measured value Nm(i,t)) for the frequency of the performance of the procedure for the first time period is determined and the measured value is compared with at least one of the estimated values (NS(i,t), NS(i,t+?t)).

Abstract: A method for automatic checking of the availability of an elevator installation having at least one elevator ascertains at least one first estimated value for a use frequency of the elevator for a first time period and/or a second estimated value for the use frequency for a second time period that begins later than the first time period. A measurement value for the use frequency for the first time period is determined and the measurement value compared with at least one of the estimated values. If the measurement value is smaller by a predetermined amount, at least one predetermined command for carrying out at least one test of the elevator installation is given, wherein in the case of availability of the elevator installation the test leads to a desired reaction. Subsequently, at least one reaction of the elevator installation is registered and compared with the desired reaction.

Abstract: The position and direction (0-27, FIG. 2) of each elevator car (A-D) in a group of cars is recorded along with time and traffic rate of the elevator group to provide a data stream. The canonic representation of the position and direction data is reduced, to eliminate symmetry (FIGS. 1, 3 and 4) resulting from the relative positions and directions of the cars being the same except for the identification of which car is at which position and direction. An entropy estimation algorithm is used to provide a plot of entropy as a function of time, which is then translated from the other data in the stream to entropy as a function of traffic rate (FIG. 5).

Abstract: An elevator control manages and controls elevators. The control efficiently minimizes the elevator service time to each floor by minimizing a standard deviation of the expected service time to various floors. The control continually monitors current elevator operation and adjusts the position of unused elevators to maintain quality and efficient elevator service by reducing user wait time.

Abstract: A power control system includes a sensing device, a switch, a controller, a first circuit, and a second circuit. The sensing device determines whether a first predetermined condition or a second predetermined condition has occurred. The controller closes the switch responsive to a signal received from the sensing device indicating the occurrence of the first predetermined condition and opens the switch responsive to a signal received from the sensing device indicating the occurrence of the second predetermined condition. When the switch is open, the first circuit is enabled to apply power to the controller and prevent the application of power to a device. When the switch is closed, the second circuit is enabled to apply power to the controller and permit the application of power to the device.

Abstract: A system for controlling elevator cars in a building having a plurality of floors includes a group controller for controlling operation of the elevator cars. The group controller predicts lobby single source traffic for determined periods. When the predicted traffic is below certain limit, cars are assigned to a lobby hall call on demand after hall call registration. When the predicted traffic is above certain limit, cars are assigned to the lobby hall call at intervals. Accordingly, car assignment is scheduled at those intervals. The schedule interval is varied based on predicted traffic and predicted round trip time of the cars. The cars are assigned to hall calls if they arrive within a schedule window. The schedule window comprises a lower and an upper tolerance that are selected around a scheduled time.

Abstract: A elevator system including a group controller for controlling the dispatching of elevator cars to the lobby. The group controller predicts lobby single source traffic for short periods. When the predicted traffic is below certain limit, cars are assigned to a lobby hall call on demand after hall call registration. When the predicted traffic is above certain limit, cars are assigned to the lobby hall call at intervals. Accordingly, car assignment is scheduled at those intervals. The traffic threshold at which the scheduled mode is activated and the traffic threshold at which it is deactivated is learned by the system. The schedule interval is varied based on predicted traffic and predicted round trip time of the cars. The number of cars assigned and sent to the lobby is varied based on predicted traffic. In order to avoid oscillations in selecting the service mode, proper delays are used to activate and deactivate the scheduled service.

Abstract: A group controller for controlling elevator cars in a building having a plurality of floors includes a traffic and traffic rate estimator for providing fuzzy estimates of traffic and traffic rate; a closed loop fuzzy logic controller for providing a control parameter in response to the fuzzy estimates of traffic and traffic rate and in response to an elevator control system output variable; and an elevator dispatcher for controlling the operation of the elevator cars during single source traffic conditions in response to the control parameter.

Abstract: A system including a group controller for controlling the dispatching of elevator cars in a building. The group controller operates by using control parameters stored in its memory. The system records car loads of cars leaving the lobby and the time intervals between their departures and uses fuzzy logic to categorize the car loads and intervals into fuzzy sets. The system determines the lobby traffic and traffic rate using fuzzy relations among car loads, departure intervals, lobby traffic and traffic rate and the fuzzy logic rules. The group controller collects traffic data during operation. The system runs simulations off-line, after single source traffic periods, using the specified control parameter values. The system collects and analyzes performance data to identify significant deviations from acceptable performances. New sets of control parameters are selected using appropriate specified rules.

Abstract: An elevator system for a multistory structure having a plurality of elevator shafts is shown which includes at least one independently movable elevator car in each elevator shaft. A digital computer with memory is used to control elevator cars including the dispatch of cars from terminal floors. A daily control parameter table in memory identifies a plurality of different methods of scheduling dispatch of elevator cars from terminal floors, groups of floors to be serviced by each elevator car, and cars in a shaft to be coupled for tandem operation. The memory is periodically read for selecting for each elevator car one of said methods of scheduling dispatch and for identifying the group of floors to be serviced by the cars. The selected method of scheduling the dispatch of cars is implemented and cars are limited to servicing the selected group of floors.

Abstract: An apparatus for detecting excess speed of an elevator car travelling in an elevator shaft includes a vertically extending measuring strip is mounted at one side of the shaft and a multichannel forked light barrier assembly mounted on the car with a pair of legs extending on opposite sides of the strip. The measuring strip has a vertically extending markings track in the form of flags side-by-side with a check track, each of which is scanned by a separate light barrier transmitting a light beam between the legs of the forked light barrier assembly. At the position of each flag there is formed a window in the check track. The speed of the elevator car is measured by detecting the time required to pass each flag and the elevator car is stopped in the case of excess speed. By reason of the arrangement of the flag track and the check track, possible faults can be detected since one light barrier must always be interrupted by reason the flags and the windows.
