TL;DR: In this article, a computer-implemented method provides location-sensitive and time-sensitive calendaring to a wireless device, such as a cell phone, pager, PDA, etc.
Abstract: A computer-implemented method provides location-sensitive and time-sensitive calendaring to a wireless device, such as a cell phone, 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 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.

TL;DR: In this paper, a vehicle information system may be used to generate route map information, schedule information, estimated time of arrival information, or the like based upon location information received from passengers' cellular phones.
Abstract: In some of the embodiments described herein, a vehicle information system may be used to generate route map information, schedule information, estimated time of arrival information, or the like based upon location information received from passenger-carried or cargo-carried wireless devices, such as passengers' cellular phones. In such circumstances, a remote device (e.g., a display device at a vehicle station, a network-connected personal computer, or a cellular phone of a person who might board a mass transit vehicle) may access the route map information, schedule information, and other information related to one or more mass transit vehicles.

TL;DR: In this article, a required time of arrival (RTA) control system (200, 220, 240) is disclosed for use with an aircraft on-board computer system (100), which is adapted to provide data for controlling aircraft flight in a manner so as to meet time-of arrival constraints at selected waypoints.
Abstract: A required time of arrival (RTA) control system (200, 220, 240) is disclosed for use with an aircraft on-board computer system (100). The control system (200, 220, 240) is adapted to provide data for controlling aircraft flight in a manner so as to meet time of arrival constraints at selected waypoints. The control system (200, 220, 240) includes means (212) for determining a time error between an estimated time of arrival and a designated RTA. A cost index predictor (216) is utilized to determine an estimated cost index parameter for meeting time of arrival constraints, while maintaining relative minimum fuel consumption. A flight profile predictor (202) is adapted to generate requisite target air speed data based on the estimated cost index parameter. In one embodiment, the system (240) includes determination of a time window based on maximum and minimum permissible cost index and speed limiting parameters. Dead-band control of the time error is also provided for maintaining stability and reducing throttle activity.

TL;DR: In this article, the authors describe an HVAC control system comprising of a server (32) having planned information, a man-machine interface (50) capable of communication with the server to provide dynamic information about building occupancy based on a change in cold water in a mains riser.
Abstract: An HVAC control system is described comprising: a server (32) having planned information, a man-machine interface (50) capable of communication with the server (32) to provide dynamic information about building occupancy based on a change in cold water in a mains riser. A central control unit (28) which can communicate with the server (32), and a room node (22, 24) for providing information about conditions within the room whereby, the information about room conditions is compared to planned information and/or dynamic information and adjustments made accordingly. The room node (22, 24) may comprise sensors (276, 278, 272, 274) which provide information about conditions in the room. Dynamic information can include changes to planned occupancy, the effect of solar heating and weather conditions. Changes to planned occupancy can be established through detecting location (internally or externally) or destination of a user; and calculating estimated time of arrival of a user.

TL;DR: An alternate destination planner for searching a navigation database in an aircraft and identifying a plurality of alternate destinations at which the aircraft can land in the event of an emergency is presented in this article.
Abstract: An alternate destination planner for searching a navigation database in an aircraft and identifying a plurality of alternate destinations at which the aircraft can land in the event of an emergency. For each identified alternate destination, the alternate destination planner calculates an estimated time of arrival (ETA) and an amount of fuel remaining upon arrival at the destination. The calculation of the ETA and the remaining fuel is based on user-modifiable parameters of aircraft speed, aircraft altitude, wind direction and speed, outside air temperature, and the type of routing the aircraft will follow from a diversion point to the alternate destination. The plurality of alternate destinations are displayed to a pilot of the aircraft according to the ETA to each alternate destination, with the closest alternate destination by time listed first. The plurality of alternate destinations are also displayed to the pilot on a map of the surrounding region that is provided to the pilot on a navigation display. A pilot may select and divert to one of the plurality of alternate destinations using a minimal number of keystrokes on a control display unit.
