A sensor tag which in use will be affixed to a vehicle for obtaining vehicle telematics data includes a battery for powering the tag and a processor running executable code to process accelerometer data. An accelerometer measures the acceleration of the tag and thereby of the vehicle, and also controls the operation of the processor. A memory is used for storing a unique tag identifier of the tag and for storing trip data including information about trips and acceleration data. Finally, a communication module is used for short range wireless communication with a mobile communications device located in the vehicle via a short range wireless communications protocol, the communication module transmitting the tag's unique identifier and a sequence of time stamped acceleration data. The mobile communications device obtains GPS data, combines this with the acceleration date and transmits this to a server for analysis.

System and method for obtaining vehicle telematics data

Among other things, safety performance of vehicles is monitored or evaluated, or both. Sensor data is received from one or more sensors at a vehicle. One or more risk sources encountered by the vehicle during a period of operation of the vehicle are identified based on the sensor data. One or more safety events experienced by the vehicle during the period of operation are identified based on the sensor data. A risk of a safety event experienced by the vehicle during the period of operation is determined based on the one or more risk sources. A safety performance of the vehicle during the period of the vehicle during the period of operation of the vehicle is determined based on the one or more safety events and the risk.

Evaluating the safety performance of vehicles

Personal safety concerns for users of vehicles can be indicated, identified, communicated, analyzed, or acted on to make the users and other participants in the technology aware of the safety concerns and to reduce the risks to the users associated with the safety concerns. Personal safety concerns can be recognized based on safety concern triggers. Once recognized, the personal safety concerns can be reported to the users and other participants in the technology by safety alerts. The safety alert can prompt one or more telematics devices at the vehicle to capture, store, or transmit telematics data, including, for example, audio, image, or video data or combinations of them. The captured telematics data can be used to verify the safety alert and the safety concern and present the captured data to a third party participant to enable the third party participant to determine an appropriate response or action.

Safety for vehicle users

A method for providing proactive driving alerts includes determining a road segment of interest, receiving GPS data and contextual data, and identifying a triggering condition in a vicinity of the segment of interest. The method also includes determining an applicability of the triggering condition to the segment of interest, retrieving an alert threshold corresponding to the triggering condition, and obtaining an action factor correlating to a user's driving behavior. The method further includes determining whether the action factor exceeds the alert threshold and providing a proactive alert related to the triggering condition to the user.

Method and system for driver alerts based on sensor data and contextual information

Among other things, information generated by sensors of a mobile phone and indicative of motion of the mobile phone and state information indicative of a state of operation of the mobile phone are monitored. Based on the monitoring, distraction by a user of the mobile phone who is a driver of a vehicle is determined.

Determining, scoring, and reporting mobile phone distraction of a driver

A tracking device and method of determining a location of a tag connected to an object. The method comprises transmitting a first message from a server over a long range communication protocol to the tag so that the tag emits short and long range distress messages; receiving at a server the long range distress messages including location data using the long range communication protocol; using the location data to determine a geographical area in which the tag is located; transmitting a message from the server to one or more mobile devices in the geographic area to enable the mobile devices to receive the short range distress messages; receiving at the mobile devices the short range distress messages from the tag and using the received short range distress message to locate the tag; and transmitting a second message from the mobile devices to the server including the location of the tag.

Tracking and theft-recovery system for mobile assets

A configurable radio frequency device includes a surface and a plurality of configurable radio frequency elements disposed on the surface. The radio frequency elements can be configured to absorb, reflect, or pass a radio transmission. A controller is configured to control the configuration of the surface by setting the state of the radio frequency elements. The controller also determines a deployment configuration for the surface by applying a series of test configurations to the surface and receiving a measurement of signal quality as measured by a receiver. The controller can then use these measurements to determine how to set the states of the radio frequency elements for the deployment configuration.

Surface for controlled radio frequency signal propagation

Data processing techniques and systems for processing telematics data associated with a vehicle, such as an automobile, to classify how the vehicle is being operated by a driver. The telematics data can include the use of image data captured by a camera of the vehicle. The image data is processed in conjunction with vehicular telematics data such as position, speed, and acceleration data of the vehicle obtained from, for example, smartphone sensors. The image data is processed and used by a processing system to provide a context for the telematics data. The image data and the telematics data are classified by the processing system to identify driving behavior of the driver, determine driving maneuvers that have occurred, scoring driving quality of the driver, or a combination of them.

Systems and methods for classifying driver behavior

An approach to determining vehicle usage makes use of a sensor that provides a vibration signal associated with the vehicle, and that vibration signal is used to infer usage. Usage can include distance traveled, optionally associated with particular ranges of speed or road type. In a calibration phase, auxiliary measurements, for instance based on GPS signals, are used to determine a relationship between the vibration signal and usage. In a monitoring phase, the determined relationship is used to infer usage from the vibration signal.

Mileage and speed estimation

A system for tracking objects includes tracking devices each attached to an object to be tracked and including a short range communications module. A server includes a processor and a memory. A mobile communications device (typically a mobile telephone) includes memory for storing an identification of the mobile device, a long range communication module for communication over a cellular communication network and a short range communications module for receiving short range signals transmitted from tracking devices. The mobile telephone also includes a location determination module to determine the location of the mobile telephone. On receipt of a short range distress signal from a tracking device, a location is obtained from the location module and a signal transmitted to the server including at least the identification of the tracking device, a time of receipt of the short range signal from the tracking device and the determined location of the tracking device when the short range signal was received.
