  • Patent number: 11590831
    Abstract: A device and a method for controlling a shading system of vehicle windows. A camera system detects image data of the head of a driver. The image data is evaluated to determine a gaze direction of the driver either as a function of a current pose of the head or body position of the driver ascertained based on the image data or as a function of eye positions of the driver determined based on image data. The shading system is controlled when the determined current gaze direction is looking in an interior rear view mirror, in the direction of the rear window, in the direction of one of the side windows, a reverse gear of the vehicle is set/activated, and the vehicle is in operation/activated. The control involves suspending or switching off a current shading/darkening of the rear window or of the side window in the gaze direction of the driver.

  • Patent number: 11108797
    Abstract: A non-transitory computer-readable medium having a program stored thereon that, when executed by one or more processors, directs a computing system to secure a communication network. The program comprises a traffic inspection engine, a domain generation algorithm (DGA) inspection engine, and a message bus communicationally coupling the traffic inspection engine and the DGA inspection engine. The traffic inspection engine is configured to identify if a traffic session containing a domain name system (DNS) request and/or response in a communication network includes a DGA generated domain and send information about the identified DGA generated domain to the DGA inspection engine via the message bus. The DGA inspection engine is configured to verify if the identified DGA generated domain is registered, and send information about the registered DGA domain to the traffic inspection engine via the message bus.

  • Patent number: 10601466
    Abstract: A sensor for sensing a usage status of an electrical device and its associated method are disclosed. The sensor is disposed at a near-end of a power line of the electrical device. The sensor provided with a magnetic detector, an analog-to-digital converter and a controller. The magnetic detector is close to the power line to detect a magnetic field change around the power line to correspondingly generate an analog signal. The analog-to-digital converter (ADC) is used to receive the analog signal and convert the analog signal to a digital signal. The controller is used to receive the digital signal and generate an indication signal to accordingly learn at least one of statuses of being turned on and turned off the electrical device.

  • Publication number: 20180167282
    Abstract: In a software-defined network (SDN) multiple servers and switches (the devices) connect into a (sub-)network under a (logically) centralized controller. As each device boots up it may have physically network connectivity but logically it is not connected to the SDN. In order to establish a logical connection the device must receive a network address assignment. There are legacy protocols for this purpose, e.g., DHCP that could be and have been adapted for use in software-defined networks. This invention specifies a different, enumeration-based method for address assignment in hierarchically-organized SDNs, which exploits the topological properties of the SDN for the purpose of device enumeration. This invention provides both Layer 2 and Layer 3 addresses for each device of the SDN.

  • Publication number: 20180147922
    Abstract: A method for controlling a sunroof of a motor vehicle that is able to be electrically adjusted by a touch-sensitive touchpad is disclosed. The sunroof is adjusted into a closed position by a first swiping movement across the touchpad. The sunroof is adjusted into an open position by a second swiping movement opposite to the first across the touchpad. The sunroof is specifically controlled depending on a position or movement of the sunroof which is caused by tapping the touchpad. The tapping the touchpad is only registered by a movement of the touchpad that is caused by tapping. A sunroof device and a motor vehicle for implementing such a method are also disclosed.

  • Publication number: 20170244733
    Abstract: Methods and systems for intrusion detection include determining a causality trace for a flagged event. Determining the causality trace includes identifying a hot process that generates bursts of events with interleaved dependencies, aggregating events related to the hot process according to a process-centric dependency approximation that ignores dependencies between the events related to the hot process, and tracking causality in a reduced event stream that comprises the aggregated events. It is determined whether an intrusion has occurred based on the causality trace. One or more mitigation actions is performed if it is determined that an intrusion has occurred.

  • Patent number: 9440537
    Abstract: A method to control functions displayed on a display unit of a vehicle uses gestures carried out in three-dimensional space. When a first gesture carried out in three-dimensional space is detected it is determined whether the detected first gesture is allocated to an activation of an operation of a function. If it is determined that the detected first gesture is the gesture allocated to the activation of the operation of the function, then the function is activated. Next a second gesture carried out in three-dimensional space is detected and it is determined whether the detected second gesture is a gesture allocated to the operation of the function. If it is determined that the detected second gesture is the gesture allocated to the operation of the function then the operation of the function is performed.

  • Publication number: 20140005895
    Abstract: A method for detecting motion for sensor-controlled activation of an operating device involves detecting a direction of the operating motion within the overlapping detection areas as a valid motion direction for actuating the vehicle equipment item. A motion through the detection areas of two sensors is detected and a total duration of the motion through the detection areas is determined. An overlap duration of the motion in an overlapping area of the overlapping detection areas is determined. A quotient from the overlap duration and the total duration is calculated and compared with a predetermined threshold separating a valid area from an invalid area. The motion is recognized as an operating motion having a valid motion direction if the quotient is in the valid area.
