摘要： This document describes techniques, apparatuses, and systems utilizing joint cost estimation for associating a detection-tracklet pair to an object. In aspects, a radar system generates a detection-tracklet pair that includes detection information about a detection for a radar reflection point in addition to tracklet information about a tracklet associated with the detection. Using the detection information and the tracklet information of the detection-tracklet pair, the radar system generates, for each potential data object of a plurality of potential data objects, a respective joint cost estimation and selects, based on the respective joint cost estimations, a data object from the plurality of potential data objects to associate with the detection-tracklet pair. The radar system then associates the detection-tracklet pair with the selected data object.

摘要： Systems and methods are provided for utilizing a connector to connect an external antenna to a mobile device. GNSS signals, associated with at least two different frequency bands, may be received at the external antenna and the GNSS signals may be transmitted to a connector module of the connector. The connector module may convert analog GNSS signals to generate digital radio frequency (RF) signals. The connector module may encrypt the digital RF signals to generate encrypted digital RF signals. The encrypted digital RF signals may be transmitted from the connector module to the mobile device. A multifrequency GNSS functionality module of the chipset may utilize decrypted digital RF signals to obtain GNSS raw measurements. The multifrequency GNSS functionality module and/or an application executing on the mobile device may utilize the GNSS raw measurements to compute position, velocity, and/or time (PVT).

摘要： Power can be preserved in a tracking device equipped with a GPS receiver and a transceiver by evaluating the proximity of the tracking device to a mobile device and enabling the GPS receiver and transceiver only in the event that the tracking device is out of the range of the mobile device. Once enabled, the location of the tracking device can be determined based on location information received from the GPS receiver. The determined location can be provided to a tracking system associated with the tracking device. The tracking system can then inform an owner of the tracking device of the determined location. Once the tracking device has been found, the GPS receiver and the transceiver can be disabled to save additional power.

摘要： Methods, systems, and apparatus, including computer programs encoded on computer storage media, for unmanned aerial vehicle authorization and geofence envelope determination. One of the methods includes determining, by an electronic system in an Unmanned Aerial Vehicle (UAV), an estimated fuel remaining in the UAV. An estimated fuel consumption of the UAV is determined. Estimated information associated with wind affecting the UAV is determined using information obtained from sensors included in the UAV. Estimated flights times remaining for a current path, and one or more alternative flight paths, are determined using the determined estimated fuel remaining, determined estimated fuel consumption, determined information associated wind, and information describing each flight path. In response to the electronic system determining that the estimated fuel remaining, after completion of the current flight path, would be below a first threshold, an alternative flight path is selected.

摘要： A system and method which enables a telematics server and its software to modify telematics device behavior based on the provisioned telecommunications plan depending on the context of the telematics device. The context may be the location, stage of manufacturing process for the device/equipment that the telematics device is fitted to (e.g. a vehicle), the speed, status of various sensors and others. This information is used to both modify device behavior in terms of how often and what is communicated to the telematics server but is also useful in modifying and provisioning new plans for the telematics device (with appropriate transmission configurations matched to the plan). The foregoing allows the telematics device to avoid operating in a way that exceeds telecom plan thresholds and limits.
