  • Patent number: 11955439
    Abstract: A semiconductor package includes a semiconductor die, a redistribution structure and connective terminals. The redistribution structure is disposed on the semiconductor die and includes a first metallization tier disposed in between a pair of dielectric layers. The first metallization tier includes routing conductive traces electrically connected to the semiconductor die and a shielding plate electrically insulated from the semiconductor die. The connective terminals include dummy connective terminals and active connective terminals. The dummy connective terminals are disposed on the redistribution structure and are electrically connected to the shielding plate. The active connective terminals are disposed on the redistribution structure and are electrically connected to the routing conductive traces. Vertical projections of the dummy connective terminals fall on the shielding plate.

  • Patent number: 11956994
    Abstract: The present disclosure is generally related to 3D imaging capable OLED displays. A light field display comprises an array of 3D light field pixels, each of which comprises an array of corrugated OLED pixels, a metasurface layer disposed adjacent to the array of 3D light field pixels, and a plurality of median layers disposed between the metasurface layer and the corrugated OLED pixels. Each of the corrugated OLED pixels comprises primary or non-primary color subpixels, and produces a different view of an image through the median layers to the metasurface to form a 3D image. The corrugated OLED pixels combined with a cavity effect reduce a divergence of emitted light to enable effective beam direction manipulation by the metasurface. The metasurface having a higher refractive index and a smaller filling factor enables the deflection and direction of the emitted light from the corrugated OLED pixels to be well controlled.

  • Patent number: 9310484
    Abstract: A device having at least one ultrasonic sensor for detecting a moving object, in particular, an approaching vehicle. To this end, the device is equipped with a control unit for determining the distance and/or the relative speed of the object. To prevent misinterpretations in the acquisition of measured values, relevant environmental conditions are simultaneously detected by an additional ultrasonic sensor and, as a correction value, provide the basis for the signal generation.

  • Patent number: 8511164
    Abstract: A detection device of a motor vehicle having a functional unit for transmitting and receiving signals. The functional unit has at least one first and one additional functional element, the signal inputs of which are subject to a comparison to determine an associative signal occurrence, and if the signals are absent in one of the functional elements, a configuration of its transmission/reception range to a road surface to be detected is performed in such a way that the corresponding functional element is forced to received signal reflections if it is functioning. A corresponding method is also provided.

  • Patent number: 8493195
    Abstract: A method is used for detecting the environment of a vehicle and utilizes a number of sensors, the sensors having different detection ranges, and a transition of an object between two detection ranges is bridged by prediction by using a handover algorithm.

  • Patent number: 8279087
    Abstract: A method for determining a parking spot including at least the following steps: measuring a parking spot and outputting a measured length of the parking spot; comparing the determined length to at least one limiting value and determining an indicator signal; outputting the indicator signal to the driver; recording vehicle dynamics signals, during a parking operation; evaluating the parking operation on the basis of the recorded vehicle dynamics signals and outputting an evaluation signal, and changing the at least one limiting value as a function of the evaluation signal and the indicator signal. An adaptive parking spot measurement is created in which an evaluation of the parking spot length is automatically adapted to the driving behavior and the driving skills of the respective driver, resulting in a particularly high degree of acceptance of the PSM system by the driver.

  • Patent number: 7786896
    Abstract: A parking assistance system for outputting parking instructions to the driver of a vehicle has a sensor device which is designed for performing a parking space measurement on the basis of parking space limits and generating parking space information on the basis of the parking space measurement; a program-controlled device which calculates the driving trajectory to be traveled on the basis of the parking space information generated and calculates a time to collision and/or a distance to collision, within which the vehicle will presumably collide with one of the parking space limits, from the parking space information generated and the calculated driving trajectory; and a warning signal transducer which generates a warning signal if the calculated period of time is less than a first limit value and/or the calculated distance to collision is less than a second limit value.
