  • Patent number: 11964171
    Abstract: A virtual beam's-eye view of a planning target volume is generated based on volumetric image data acquired immediately prior to radiation therapy by a radiation therapy system. The virtual beam's-eye view can then be displayed to confirm that, with the patient disposed in the current position, the planned beam-delivered treatment extends beyond the surface of the skin. In some embodiments, the virtual beam's-eye view can be displayed in conjunction with a beam's-eye view that is generated based on volumetric image data acquired during treatment planning, to create a blended beam's-eye view. In some embodiments, a field outline of a treatment beam can be superimposed on the blended beam's-eye view, thereby illustrating whether the planned beam-delivered treatment extends beyond the surface of the skin of the patient. The blended beam's-eye view can facilitate a manual confirmation process that verifies the planned beam-delivered treatment extends beyond the surface of the skin.

  • Patent number: 11104279
    Abstract: A vehicular vision system includes a camera disposed at a vehicle and having a field of view rearward of the vehicle, a light source disposed at the vehicle and operable to emit light, and a control including an image processor. The control, responsive to detection of the object present in the field of view of the camera, determines a region of the field of view of the camera at which a detected object is located. The control determines an illumination level at the detected object and, responsive to the determined illumination level at the detected object being greater than an upper threshold level or less than a lower threshold level, controls the respective individually controllable light segment of the light source for that region of the field of view of the camera at which the detected object is located to adjust intensity of light emitted by that light segment.

  • Patent number: 10481271
    Abstract: An automotive lighting system for a vehicle includes a taillight disposed at a vehicle equipped with an external object detection system. The taillight includes a housing that contains a light source that is operable to illuminate at least rearward of the equipped vehicle. The external object detection system includes a LIDAR sensor that is disposed in the housing of the taillight. The LIDAR sensor is operable to emit optical signals at least rearward of the equipped vehicle, where optical signals reflected back to the LIDAR sensor are processed by an electronic control unit of the external object detection system. Processing of reflected optical signals by the electronic control unit detects an object present exterior of the equipped vehicle. Also, processing by the electronic control unit may include use of 3D imaging techniques to generate a 3D image of the object present exterior of the equipped vehicle.

  • Publication number: 20140197782
    Abstract: A wireless charger with combined electric radiation shielding and capacitive sensing functions is provided. The wireless charger comprises a charging module, a capacitive sensor, and a control unit. The charging module comprises a first coil, a placing area, and a comb-shaped shielding located between the placing area and the first coil. The capacitive sensor is connected to the comb-shaped shielding to detect the capacitance varient between the comb-shaped shielding and the environment. When the wireless charger is in a standby mode, the comb-shaped shielding is for sensing capacitance. When the capacitance varient exceeds a predefined threshold and an electronic device for wireless charging is placed on the placing area, the control unit switches the wireless charger to a charging mode and the comb-shaped shielding is for electric radiation shielding.
