A method for monitoring vehicle motion using a mobile device associated with a user including collecting activity data at a mobile device associated with the user; determining a user activity state based on the activity data; determining motion data collection parameters associated with an operating state of the mobile device, based on the user activity state; and collecting motion data at the mobile device based on the motion data collection parameters.

Systems and methods include a method for detecting and identifying access points. Signals transmitted by access points in one or more mobile telecommunications networks within range of a mobile wireless scanning system are received by the mobile wireless scanning system. A presence of the access points is detected by the mobile wireless scanning system. Locations of the access points are determined by the mobile wireless scanning system using the signals transmitted by the access points. The locations of the access points are logged by the mobile wireless scanning system. Location and identifying information for the access points are provided by the mobile wireless scanning system to a receiving client.

Locating systems and methods for wireless seat belt monitoring in vehicles with removable or reconfigurable seats are provided herein. An example remote transceiver can be centrally located on a seat that is configured to be rearranged within a vehicle. The remote transceiver can include a processor and memory for storing instructions that include a unique code identifying the remote transceiver. The processor executes the instructions to receive low power signals from transmitters within an interior of the vehicle, determine received signal strength values of the low power signals. The received signal strength values are used by the vehicle receiver to determine a location of the remote transceiver within the vehicle.

A method for communication includes detecting, at a first station in a wireless network, a beacon transmitted over the wireless network by a second station having multiple antennas. In response to the beacon, a request-to-send (RTS) frame is transmitted over the wireless network using a multi-carrier modulation scheme from the first station to the second station. The first station receives a clear-to-send (CTS) frame transmitted over the wireless network, in response to the RTS frame, by the second station via the multiple antennas using the multi-carrier modulation scheme, and estimates an angle of transmission from the second station to the first station based on the received CTS frame.

Systems and methods for facilitating the sorting of assets to sort locations. In various embodiments, a sort employee scans an asset indicia using a user device, which stores asset data corresponding to the stored asset. As the sort employee nears a sort location (e.g., a delivery vehicle) with the asset and the user device, the user device automatically communicates wirelessly with a sort location receiver to associate the asset data with data indicative of the sort location where the user deposits the asset. In various embodiments, a device may determine whether the user device is proximate the appropriate sort location for the item, and may generate an alert upon a determination that the user device is proximate an incorrect sort location.

A drone-based monitored storage system includes a shipment storage with an interior storage area and a drone storage area, an internal docking station, and an internal monitor drone disposed within the shipment storage that aerially monitors the items being shipped within the interior storage area. The monitor drone includes an airframe, battery, onboard controller, lifting engines and lifting rotors responsive to flight control input, communication interface, sensor array that gathers sensory information as the drone moves within the interior shipment storage area of the shipment storage, and a drone capture interface that can selectively mate to the internal docking station to hold the monitor drone in a secure position. The monitor drone can gather the sensory information (such as environment information, image information, multidimensional mapping information, and scanned symbol information) and autonomously detect conditions of items being shipped based upon the sensory information from the sensor array.

A method, computer program, and computer system of a base station is provided for determining a location of a mobile device by receiving data from a mobile device associated with a location of the mobile device and generating a world model database corresponding to a physical location of the base station. The received data is constrained based on the generated world model database, and an updated location of the mobile device is determined based on the constrained data.

Drone-based systems and methods for conducting a modified inspection of a delivery vehicle are described. A system has a delivery vehicle transceiver and an inspection drone paired to the vehicle that aerially inspects the vehicle. The delivery vehicle transceiver has a user interface and a wireless radio, while the paired inspection drone has a housing, onboard controller, memory storage, lifting engines, and a communication interface. The drone's onboard controller is operative to identify different existing delivery vehicle inspection points from an inspection profile record; receive an inspection update message from the communication interface; update the existing delivery vehicle inspection points with additional inspection points to yield a targeted inspection points corresponding to respective parts of the delivery vehicle; and conduct the modified inspection of the delivery vehicle by gathering the detected sensor-based inspection information related to each of the targeted inspection points.

The present description relates to a frequency-based wake-up device and a sensor communication device using such the same. The present invention comprises: a RF signal to voltage converter for receiving a wireless signal including a first signal and a second signal and converting the frequency of the preamble to voltage to generate a driving voltage and provide the same; a decoder activated by the driving voltage and extracts ID information of the sensor communication device by decoding the second signal; and a signal processor that is activated by the driving voltage and compares the extracted ID information of the sensor communication device by the decoder with pre-stored ID information of a pre-determined sensor communication device and notifies of reception of a wake-up signal when the extracted ID information and the pre-stored ID information are the same.

Methods, devices and computer readable storage medium for ranging between a tag device (410) and plurality of anchor devices (405). The tag device (410) broadcasts a first poll message (605) to a plurality of anchor devices (405). The tag device (410) receives a plurality of response messages (620) for the first poll message (605) from the plurality of anchor devices (405). The plurality of response messages (620) are transmitted by the plurality of anchor devices (405) at a plurality of response time points. The plurality of response time points are associated with ranks of respective distances among a plurality of distances between the tag device (410) and the plurality of anchor devices (405). After receiving the plurality of response messages, the tag device (410) broadcasts a second poll message to the plurality of anchor devices (405). The ranging efficiency may be improved.
