Examples relate to digital context aware (DCA) data collection. In some examples, a DCA start location component is positioned at a first location along a travel route, and a DCA end location component is positioned at a second location along the travel route. In response to using a wireless interface to detect the DCA start location component, data collection of measurements by a sensor are initiated. In response to using the wireless interface to detect the DCA end location component, the data collection by the sensor is halted.

Methods of, systems for, and articles of manufacture for wireless communication between a vehicle locating unit and peripheral devices that are disposed on or in the same object, the method including the steps of adapting the peripheral devices to generate transmission signals to be received by the vehicle locating unit; generating transmission signals by at least one of the peripheral devices; adapting the vehicle locating unit to listen for the transmission signals for a first period of time during a second period of time that is longer than the first period of time; acknowledging detected transmission signals from any of the peripheral devices; upon acknowledgement, establishing a communication link between the vehicle locating unit and a corresponding source of the detected transmission signals; and communicating data between the vehicle locating unit and the corresponding source of the detected transmission signals in accordance with discrete timing information.

A personal items network, comprising a plurality of items, each item having a wireless communications port for coupling in network with every other item, each item having a processor for determining if any other item in the network is no longer linked to the item, each item having an indicator for informing a user that an item has left the network, wherein a user may locate lost items. A method for locating lost personal items, comprising: linking at least two personal items together on a network; and depositing one or both of time and location information in an unlost item when one of the items is lost out of network.

A device moving in a space determines one or more zones around it, wherein the one or more zones are linked to the device and move together with the device through the space. The device detects if a border of a first of the one or more zones starts to intersect or stops to intersect with a border of an area inside the space. If the detecting is affirmative, the device transmits information related to the intersection. An apparatus receives this information from the device and adapts a status value of the area in dependence of the received information.

A system and device that will notify roadway maintenance workers of an approaching mass transit vehicle and, conversely, will notify the operators and administrators of mass transit vehicles of roadway maintenance workers within the vicinity of an approaching section of track.

A method for using barrier systems includes positioning a plurality of barrier systems at a location, each barrier system having: a barrier having an interior surface and an opposing exterior surface, the interior surface bounding a chamber that is adapted to receive a ballast; and a light assembly secured to the barrier, the light assembly comprising a housing having a lens that at least partially bounds a compartment, a light source at least partially disposed within the compartment, and programmable circuity in electrical communication with the light emitting device. A control device is used to communicate wirelessly with programmable circuity of each barrier system after the barrier systems are positioned at the location so that data is transferred between the control device and the programmable circuity of each barrier system.

A system includes an energy management system configured to be communicatively coupled with a communication system of a vehicle that travels on a trip along a route. The energy management system is configured to be removably coupled with the communication system such that the energy management system is mechanically disengageable from the communication system. The energy management system is further configured to receive data parameters from the communication system and to generate at least one of a trip plan or a control message for the vehicle based on the data parameters. The trip plan and/or the control message dictates tractive and braking efforts of the vehicle during the trip. The energy management system is configured to communicate the trip plan and/or the control message to the communication system for the communication system to implement for controlling movement of the vehicle during the trip.
