A computer-implemented method provides location-sensitive and time-sensitive calendaring to a wireless device, such as a cellphone, pager, PDA, etc. A user's calendar is maintained with a number of appointments, start times and end times for the appointments, meeting place and a list of attendees for the appointments. When the present time reading is within a predetermined minimum of a meeting start time of an appointment of a calendar of a user, the location of the user is determined based on the location of the wireless device. The location of the meeting place is also determined. Using historical data (of the user or others), the estimated time of arrival of the user at the meeting place is determined. If the estimated time of arrival is after the meeting start time, then a late message may be sent to the user and/or to the other meeting attendees.

An autonomous apparatus for generating real-time estimates of the time of arrival of vehicles at user selected sites. The apparatus is comprised of two separate components, a vehicle unit which is carried by each vehicle and a user unit which is carried by each user. The vehicle unit determines time and geographical position at predetermined locations and broadcast these data to the user units through a wireless communications medium. The user unit receives the time and position information and adds it to computer memory records of similar data received over a prior period of time. The combined set of recorded data is used to estimate the time that the broadcasting vehicle will arrive at a specific location, that location having been specified by the user on a previous occasion by pressing a button on the user unit when the vehicle was stopped at the selected location. The estimated arrival time is presented on a display. The system operates without any assistance or information input from humans and its user require no special knowledge or skills. It is ideally suited for application to school bus transportation services.

An individualized baggage tracking and notification system provides airline baggage tracking information to individual customers for purposes of customer convenience and/or theft avoidance. The individualized baggage tracking information may indicate, for each of one or more baggage items affiliated with the customer, indicia of one or more baggage handling nodes visited by the baggage items, indicia of recorded arrival times of the baggage items at the visited nodes, indicia of one or more baggage handling nodes not yet visited by the baggage items and indicia of projected arrival times of the baggage items at those nodes. In an instance where a customer baggage item has reached a terminating node (e.g., a baggage carousel), the system may indicate the arrival time of the baggage item at the terminating node; or in the instance the baggage item has not yet reached the terminating node, the system may indicate a projected arrival time of the baggage item at the terminating node.

The disclosed embodiments relate to prediction of traffic dynamics. A descriptive model is provided that uses historical probe data to create “tidal-like” patterns for the usual dynamics on the road network and creates a framework for taking a future time, e.g. in terms of month, day, time, and suggesting a typical speed for the specified road network link at that specific time. With this model, better predictions for estimated time of arrival will be derived. As opposed to blindly extrapolating from a static model, the disclosed embodiments dynamically adapt to current conditions using real time data to adapt, based on current conditions, the model from which a predicted speed may be determined.

The customer is permitted to access the database showing location, the time and/or distance of T-P, the projected time of arrival, duration, and time of completion. The customer selects a communications channel for call ahead time and delay notice. Additionally, the system and method may be deployed over a distributed computed system which includes a supplemental computer and a supplemental database. The web based server forwards to the supplemental computer and supplemental database the customer selected communications channel, mode, call ahead and delay data.

A method and system for achieving highly available, fault-tolerant execution of components in a distributed computing system, without requiring the writer of these components to explicitly write code (such as entity beans or database transactions) to make component state persistent. It is achieved by converting the intrinsically non-deterministic behavior of the distributed system to a deterministic behavior, thus enabling state recovery to be achieved by advantageously efficient checkpoint-replay techniques. The method comprises: adapting the execution environment for enabling message communication amongst and between the components; automatically associating a deterministic timestamp in conjunction with a message to be communicated from a sender component to a receiver component during program execution, the timestamp representative of estimated time of arrival of the message at a receiver component. At a component, tracking state of that component during program execution, and periodically checkpointing the state in a local storage device. Upon failure of a component, the component state is restored by recovering a recent stored checkpoint and re-executing the events occurring since the last checkpoint. The system is deterministic by repeating the execution of the receiving component by processing the messages in the same order as their associated timestamp.

The present invention is a method of coordinating an activity at a destination includes receiving a first signal indicative of a first location of a first party (110). The first signal is received at a destination of the first party. A second signal indicative of a second location of a second party is received at a destination (112), which is also the destination of the second party. A schedule is created (150) to coordinate the activity automatically at the destination. The schedule is based on the first and second signals indicative of the first and second locations and may include additional functions such as the estimated times of arrival of the first and second parties (120, 122). Also, the present invention is a method of notification upon arrival at a predetermined location (200) that includes receiving a first signal indicative of the location of a first party (210). A second signal is transmitted to a second party (230) when the location of the first party is equal to a first predetermined location (220). The activity is coordinated at a second location based on the second signal.
