  • Publication number: 20230004223
    Abstract: An eye tracking system comprising a controller configured to receive a reference image of an eye of a user and a current image of the eye of the user. The controller is also configured to determine a difference between the reference image and the current image to define a differential image. The differential image has a two dimensional pixel array of pixel locations that are arranged in a plurality of rows and columns. Each pixel location has a differential intensity value. The controller is further configured to calculate a plurality of row values by combining the differential intensity values in corresponding rows of the differential image and to determine eyelid data based on the plurality of row values.

  • Patent number: 11486595
    Abstract: An Air Handling Unit for a ventilation system in a building has supply and extract air channels, each with an inlet and an outlet for guiding air to and from a building. Each air channel includes a damper controlling air flow. The air channels are in a heat exchanging relation to each other. The AHU also includes a fan and an Electronic Control Unit. The ECU outputs a defrost cycle initiation signal to defrost the heat recovery arrangement. The ECU outputs a defrost cycle termination signal to end the defrost cycle upon indication of the defrosting being completed. To optimize the defrost cycle time the ECU changes the first or second criterion for defrost cycle termination signal depending on the time for performing the defrost cycle such that the time period of the defrost cycle is prolonged/shortened when the defrost cycle time period is shorter/longer than preferred.

  • Publication number: 20220261079
    Abstract: Techniques for controlling light sources used in eye tracking are described. In an example, an eye tracking system generates a first image and a second image showing at least a portion of the user eye illuminated by a predetermined set of illuminators of the eye tracking system. The eye tracking system determines a first position of a glint in the first image and a second position of the glint in the second image. Each of the first position and the second position is relative to a pupil edge. The eye tracking system predicts a third position of the glint relative to the pupil edge based on the first position and the second position. Further, the eye tracking system determines, from the predetermined set, an illuminator that corresponds to the glint and determines, based on the third position, whether to power off the illuminator to generate a third image of at least the portion of the user eye.

  • Patent number: 11418655
    Abstract: A method (400) includes receiving a microphone audio signal (132) and a playout audio signal (112), and determining a frequency representation (324) of the microphone audio signal and a frequency representation of the playout audio signal. For each frequency representation, the method also includes determining features (302) based on the frequency representation. Each feature corresponds to a pair of frequencies (342) of the frequency representation and a period of time between the pair of frequencies. The method also includes determining that a match (212) occurs between a first feature based on the frequency representation of the microphone audio signal and a second feature based on the frequency representation of the playout audio signal, and determining that a delay value (222) between the first feature and the second feature corresponds to an echo within the microphone audio signal.

  • Publication number: 20220228878
    Abstract: A reversing assistant system for a vehicle comprising a first path memory for storing a continuously recorded current forward segment, and a second path memory for storing a recorded preceding forward segment. The system is configured to transfer the content of the first path memory to the second path memory when the vehicle resumes forward motion after reversing, and it further comprises a path merger observer configured to repeatedly assess whether the current forward segment is mergeable with the preceding forward segment and, if so, to trigger a path merging operation. The system further comprises a path merger configured to execute a path merging operation and to substitute its output into the first path memory and a drive assistance unit configured to determine drive actions causing the vehicle to reverse along a recorded forward segment or a merged segment.
