Publication number: 20160282464Abstract: The present method and system relates to the determination of elevation angles for the case in which more than one target object is situated within a radar cell. Through the estimation according to the present invention of the elevation angles in multi-target scenarios, even in such cases both azimuth angles and elevation angles can be determined, and a reliable classification of the respective target objects can then take place. The present system also relates to a motor vehicle having a radar system that includes an azimuth and elevation angle estimation method and system.Type: ApplicationFiled: September 25, 2013Publication date: September 29, 2016Inventors: Michael SCHOOR, Volker GROSS

Publication number: 20160282466Abstract: A trailer of a semi-trailer truck includes a cargo container having affixed at a height of approximately forty-six inches from a base of the cargo container a hole that is approximately two and one half inches in diameter. A fleet pan enclosure in a form of a housing encompassing a communications circuitry, a global positioning device and an ultrasound sensor projects into an interior cavity of the cargo container through the hole. The global positioning device provides an accurate reporting of a location of the semi-trailer truck to a central server. An antenna of a communication circuitry is fully encompassed within the housing. The location at which the housing is affixed provides for an effective measuring and reliable locating of a stored transport item inside the interior cavity of the cargo container through the hole.Type: ApplicationFiled: March 24, 2015Publication date: September 29, 2016Inventor: Jim Epler

Publication number: 20160282467Abstract: An ultrasonic diagnostic imaging system produces spatially compounded trapezoidal sector images by combining component frames acquired from different look directions. A virtual apex scan format is used such that each scanline of a component frame emanates from a different point (El, En) on the face of an array transducer (12) and is steered at a different scanning angle. For different component frames the scanlines are steered at respectively different angles. In the illustrated example, the scanlines of each component frame are incremented by five degrees relative to the corresponding scanlines in a reference component frame. When the component frames are combined for spatial compounding, the maximum number of component frames are combined over virtually the entire image field.Type: ApplicationFiled: April 24, 2014Publication date: September 29, 2016Inventor: LARS JONAS OLSSON

Publication number: 20160282469Abstract: Aspects of the disclosure include a method for sharing satellite navigation messages. The method includes receiving a download report from a receiver. The download report indicates what portions of a satellite navigation message are currently stored by the receiver. The method also includes determining whether to update a satellite navigation message database associated with a server based on the portions of the satellite navigation message stored by the receiver. In response to determining that the satellite navigation message database should be updated, the method further includes requesting the receiver to transmit a subset of the satellite navigation message currently stored by the receiver to the server; receiving the subset of the satellite navigation message; and updating the satellite navigation message database associated with the server based on the received subset of the satellite navigation message.Type: ApplicationFiled: March 17, 2016Publication date: September 29, 2016Applicant: Marvell World Trade Ltd.Inventors: BoChih LIU, Zhike Jia, Jian Chen, Zhicui Lu, Juhong Xing, Feng Xu
