Cargo inspection, monitoring and securement in self-driving trucks
The technology relates to cargo vehicles. National, regional and/or local regulations set requirements for operating cargo vehicles, including how to distribute and secure cargo, and how often the cargo should be inspected during a trip. However, such regulations have been focused on traditional human-driven vehicles. Aspects of the technology address various issues involved with securement and inspection of cargo before a trip, as well as monitoring during the trip so that corrective action may be taken as warranted. For instance, imagery and other sensor information may be used to enable proper securement of cargo before starting a trip. Onboard sensors along the vehicle monitor the cargo and securement devices/systems during the trip to identify issues as they arise. Such information is used by the onboard autonomous driving system (or a human driver) to take corrective action depending on the nature of the issue. |

LIDAR systems are less accurate in the presence of background light which can saturate the sensors in the LIDAR system. The embodiments herein describe a LIDAR system with a shutter synchronized to a laser source.

To mitigate the effects of background light, during a second time period, the laser source is synched with the shutter so that the background light is measured (in the absence of the reflections) which can be used to remove the effects of the background light from a range measurement. |

Use of VNN1 as a biomarker and a therapeutic target in sarcomas
Sarcomas are rare malignant tumors arising from the mesenchymal tissues at all body sites. The inventors show that in a mouse model of p16/p19 deficiency prone to tumor development, the absence of the mouse pantetheinase Vnn1 enhances the frequency of aggressive fibrosarcomas. They also show that reintroduction of a catalytically active form of the Vnn1 pantetheinase limits tumor growth in vivo. Interestingly, VNN1 expression in human sarcomas is associated with reduced aggressiveness and lower risk of metastatic relapse in patients. In conclusion, Vnn1 represents a novel marker of sarcoma and may modulate tumor aggressiveness by sustaining myofibroblast cell differentiation, thereby limiting evolution towards undifferentiated tumors. The present invention relates to the use of Vnn1 as a biomarker and a therapeutic target in sarcomas. |

Determining a relative movement direction
An apparatus, for determining a relative direction of a movement of an encoder object depending on a magnetic field which is generated or influenced by the encoder object. A magnetic field sensor generates two sensor signals based on the magnetic field, that indicate a profile of the magnetic field in the event of a relative movement between the encoder object and the magnetic field sensor, that fluctuate around a mean value and are phase-shifted 90° to one another. The processing circuit calculates an angle based on the two sensor signals, and determines the relative direction of the movement of the encoder object based on a gradient of the angle between a switch-on time of the apparatus and a threshold value angle which is reached thereafter or based on a gradient of the angle between the situation of two successive threshold value angles being reached. |

Method for updating strapdown inertial navigation solutions based on launch-centered earth-fixed frame
The present invention relates to a method for updating strapdown inertial navigation solutions based on a launch-centered earth-fixed (LCEF) frame (g frame). The present invention uses the g frame as a navigation reference frame of a medium-to-short-range surface-to-surface missile. This is beneficial to establish a relative relationship between the missile and the ground so as to keep the same missile parameters required by a missile control and guidance system. The calculation of a navigation algorithm in the g frame is moderate, which is suitable for an embedded system. |

Encoding parking search cruise routes using bloom filters
A parking cruise request is received. A network version starting segment is identified and a route determination algorithm is expended starting at the network version starting segment. When the route determination algorithm is expanded to a new segment, a cost value is determined for the new segment based at least on the likelihood of finding parking on the new segment. Responsive to determining that the likelihood of finding parking along the cruise route does satisfy the threshold probability requirement, map version agnostic identifiers for each segment of the cruise route are generated. Each of the map version agnostic identifiers are coded using at least one coding function to generate coded map version agnostic identifiers. A bloom filter having the coded map version agnostic identifiers as members is generated. A parking cruise route response comprising the bloom filter is provided such that a mobile apparatus receives the parking cruise route response. |

Method and apparatus for map matching trace points to a digital map
An approach is provided for pattern-based map matching of a probe trace to a digital map. The approach involves querying the digital map for a set of road links within a threshold distance of a probe point. The approach also involves determining a match starting point for each road link of a set of road links. The approach further involves selecting a sampled probe point from the probe trace. The approach also involves generating one or more patterns for said each road link based on the match starting point, the sampled probe point, the topology polyline, or a combination thereof. The approach further involves selecting a matched road link from among the set of road links based on the one or more patterns. The probe point is then snapped to the matched road link. |

Fully automatic survey technology (FAST)
FAST provides a method of “bootstrapping” a pseudo-range (PR) stage and one or more carrier-phase (CP) stages to quickly produce a highly accurate, high integrity receiver-to-receiver lever arm survey based on differential GNSS processing. The lever arm estimates of a previous stage are used to resolve the carrier phase ambiguities of the next stage. The method can be integrated with the warm-up of the integrity monitors to reduce the entire survey and warm-up startup time to 90 minutes or less, which is critical for mobile and make shift and precision approach and (automated) landing operations. |
