Publication number: 20240067182Abstract: This disclosure provides systems, methods, and devices for vehicle driving assistance systems that support image processing for vehicular monitoring operations. In a first aspect, a method of monitoring includes receiving first image data from a first camera oriented in a first direction with a first field of view facing a user; receiving second image data from a second camera oriented in a second direction different from the first direction, the second camera having a second field of view corresponding to a field of view of the user; determining a set of regions of interest based on the second image data; determining a gaze direction of the user based on the first image data; and determining an attentiveness score based on correspondence between the set of regions of interest and the gaze direction. Other aspects and features are also claimed and described.Type: ApplicationFiled: August 25, 2022Publication date: February 29, 2024Inventors: Gustav Nils Ture Persson, Per Cronvall

Patent number: 9582412Abstract: The present invention relates to the field of digital media recording such as video or audio, where compression is used to reduce the amount of data to save onto a data storage. In particular the invention relates to recording media, wherein the memory area required to store the media is unknown. The invention discloses a method for recording digital streamed media with a number of media frames in a memory by encoding each media frame into an encoded frame comprising a first number of sets of data, representing different characteristics of the media stream. The invention further relates to detecting if the data storage is full and if the data storage is full, storing new frames in the data storage previously occupied by the data sets representing the least prioritized characteristics of the previously stored encoded frames. The invention also relates to a corresponding media recorder and computer program.Type: GrantFiled: June 21, 2010Date of Patent: February 28, 2017Assignee: SAAB ABInventors: Henrik Dikvall, Per Cronvall

Patent number: 9308918Abstract: An object collision warning system for a motor vehicle comprises a sensing means (11) adapted to sense a surrounding of the motor vehicle and a processing means (14) adapted to detect objects in a surrounding of the motor vehicle by processing a signal provided by the sensing means (11), to perform an estimation of a collision probability between the vehicle and the detected object, and to output a corresponding signal in case the collision probability is non-negligible. The processing means (14) is adapted to determine, after having passed a curve, information describing the passed curve, to store the curve describing information, and to use the curve describing information of at least one previously passed curve for determining the vehicle path in a current curve in the estimation of the collision probability.Type: GrantFiled: December 22, 2010Date of Patent: April 12, 2016Assignee: AUTOLIV DEVELOPMENT ABInventors: Jonas Elbornsson Skogsstjarna, Per Cronvall

In particular the invention relates to recording media, wherein the memory area required to store the media is unknown. The invention discloses a method for recording digital streamed media with a number of media frames in a memory by encoding each media frame into an encoded frame comprising a first number of quality layers, such as the quality layers in JPEG2000. The invention further relates to detecting if the data storage is full and if the data storage is full, storing new frames in the data storage previously occupied by the quality layer representing the highest resolution of the previously stored encoded frames. The invention also relates to a corresponding media recorder and computer program.Type: GrantFiled: June 21, 2010Date of Patent: December 9, 2014Assignee: Saab ABInventors: Henrik Dikvall, Per Cronvall
