The present invention relates to a method and arrangement in an ad-hoc network for synchronizing a multiple of radio transceiver arrangements with different characteristics that make use of a common air interface. Each transceiver arrangement comprises at least two transceivers which mutually communicate via a radio transmission link. All transceivers synchronize to a common synchronization signal comprising two staggered beacon pulse series signals (TX1, TX2) which have the same repetition rate. The transceivers synchronize their internal timers which control the signal transmission from the transceivers, to the strongest one of the two beacon pulse series signals (TX1, TX2) by listening during one of the corresponding sets of time windows (RX1, RX2). Between the reception of two beacon pulses, each transceiver transmits beacon pulses itself, thus contributing to the generation of the other beacon pulse series signal, on which other transceivers can lock.

The invention discloses a parking system path planning method based on dynamic time windows, and belongs to the technical field of path planning. The method is characterized by comprising the following steps: S1, building a work environment model of AGVs in an intelligent garage in a topological method; S2, setting priority for each AGV and each car parking/picking task according to different evaluation criteria; S3, using a Dijkstra algorithm to plan a shortest possible path for an AGV accepting a task; S4, arranging feasible path time windows; S5, designing conflict resolution strategies according to different types of conflicts; and S6, planning a conflict-free optimal path for the AGV using a parking system path planning algorithm based on dynamic time windows. A time-sharing use strategy is used, and the Dijkstra algorithm and a time window method are combined effectively, so that the problem that the existing multi-AGV path planning is of poor flexibility and is prone to deadlock or collision conflict is solved effectively, and a shortest conflict-free optimal path can be planned for an AGV accepting a task. In addition, the overall operation efficiency of an intelligent three-dimensional parking system can be improved effectively, and the car parking/picking waiting time can be reduced for social members.

Computer-based methods and systems for dynamically scheduling the distribution of products and services among a system of routes and timeslots are provided. Exemplary embodiments provide a Route and Timeslot Scheduler (the “RTS”), which controls the creation, quantity, and allocation of schedule stops (or events) for each timeslot of each route based upon a calendar and template system. Each route typically represents a geographic area to which products can be delivered. Each timeslot typically represents a window of time, during which delivery stops (or events) can be scheduled. Scheduled stops/events are created based upon defaults which are specified in the template system. A calendar system is provided to specify which routes and timeslots, which would otherwise be available based upon the template system, are actually applicable to be scheduled on a given calendar day. The RTS creates scheduled stops for a designated point.

A system and method for learning models from scarce and/or skewed training data includes partitioning a data stream into a sequence of time windows. A most likely current class distribution to classify portions of the data stream is determined based on observing training data in a current time window and based on concept drift probability patterns using historical information.

Methods and systems are described for reducing the number of false alarms in fault correlation software used to detect and diagnose faults in computer networks and similar systems. The fault correlation software includes rules that monitor a number of indicators that, if occurring together over a window of time, are known to cause or reflect the occurrence of a fault. The method involves monitoring the transition of these indicators from one state to another over the time window and determining the extent of the correlation of the transitions of the indicators. The determination that indicators monitored by a rule do not correlate closely in their transitions is used to reduce the likelihood of the rule finding correlation of the indicators as a whole. This in turn reduces the number of false alarms which the rule-based system might otherwise have transmitted.

An apparatus for computed tomography (CT) imaging of a cyclically moving organ includes a positional state monitor (24, 40) that monitors a positional state of the cyclically moving organ such as the heart. A cone-beam CT scanner (10) acquires image data at least within a plurality of time windows. Each time window is centered about an occurrence of a selected positional state of the organ. A window analyzer (38) selects a data segment within each time window such that the data segments combine to form a complete data set covering a selected angular range. A reconstruction processor (44) reconstructs the selected data segments into an image representation.

Embodiments of this invention provide methods for detecting a denial of service attack (DoS) and isolating traffic that relates to the attack. The method may begin by collecting network traffic data by observing individual packets carried over the network. The data may then be compiled into a time series comprising network traffic data relating successive time-intervals. A difference value based upon the entry in the time series for a large time-window and for a small time-window. A deviation score may then be determined by calculating the ratio of the difference values. The deviation score may indicate whether an attack occurred. In an embodiment of the invention, an attack is deemed to occur if the deviation score is between 0.6 and 1.4.

An electronic lock box contains a secure compartment for storing keys to a structure. A linear actuator moves in one direction opening the door to the secure compartment, and moves in the opposite direction releasing a shackle that holds the lock box to the structure. A lock box system uses an encryption algorithm to diversify user PIN data at a central computer, and stores that diversified information on a memory card for later use when the user attempts to access a lock box. The central computer and electronic lock box both keep track of system “epoch time,” and the memory card must be presented to the electronic lock box within a correct epoch time window for the diversified PIN data to be successfully decrypted and compared to the user's PIN data that is entered on a keypad of the electronic lock box.
