  • Publication number: 20240075921
    Abstract: A method and a system for the at least partially automated parking of a motor vehicle, wherein a trajectory is provided, the motor vehicle is driven in an at least partially automated manner along the trajectory, and the trajectory is displayed on a display device with an overview map of an environment. Furthermore, by at least one camera, environment regions of the environment are captured as respective image data, at least some of which are saved allocated to the related environment regions, wherein at the time of display of the overview map, all of the image data saved up until this point in time are displayed in corresponding display regions on the overview map.

  • Publication number: 20220144624
    Abstract: A MEMS sensor includes a proof mass that is suspended over a substrate. A sense electrode is located on a top surface of the substrate parallel to the proof mass, and forms a capacitor with the proof mass. The sense electrodes have a plurality of slots that provide improved performance for the MEMS sensor. A measured value sensed by the MEMS sensor is determined based on the movement of the proof mass relative to the slotted sense electrode.

  • Patent number: 10717641
    Abstract: In some embodiments, a sensor includes a microelectromechanical system (MEMS) structure, a cover, and a bump stop. The MEMS structure is configured to move responsive to electromechanical stimuli. The cover is positioned on the MEMS structure. The cover is configured to mechanically protect the MEMS structure. The bump stop is disposed on a substrate and the bump stop is configured to stop the MEMS structure from moving beyond a certain point. The bump stop is further configured to stop the MEMS structure from making physical contact with the substrate. Moreover, the cover is configured to apply a force to the MEMS structure responsive to a voltage being applied to the cover.

  • Patent number: 9766264
    Abstract: Described herein is an accelerometer that can be sensitive to acceleration, but not anchor motion due to sources other than acceleration. The accelerometer can employ a set of electrodes and/or transducers that can register motion of the proof mass and support structure and employ and output-cancelling mechanism so that the accelerometer can distinguish between acceleration and anchor motion due to sources other than acceleration. For example, the effects of anchor motion can be cancelled from an output signal of the accelerometer so that the accelerometer exhibits sensitivity to only acceleration.

  • Patent number: 8966389
    Abstract: Embodiments of the present invention provide intuitive, easily used, and efficient visual representation of positions of interest to a user within a sequentially ordered information encoding. In particular, various embodiments of the present invention provide a heat-map-like representation of the relatedness, at each location or position within a sequentially ordered information encoding, of the contents of the information encoding at or near the position to a specified search criterion. The heat-map visual representation allows a user to identify positions of particular interest, with respect to the specified search criterion, and to directly access the information at those positions, allowing the user to avoid time-consuming and inefficient hit-or-miss searching techniques.

  • Patent number: 8069726
    Abstract: An angular velocity sensor has two masses which are laterally disposed in an X-Y plane and indirectly connected to a frame. The two masses are linked together by a linkage such that they necessarily move in opposite directions along Z. Angular velocity of the sensor about the Y axis can be sensed by driving the two masses into Z-directed antiphase oscillation and measuring the angular oscillation amplitude thereby imparted to the frame. In a preferred embodiment, the angular velocity sensor is fabricated from a bulk MEMS gyroscope wafer, a cap wafer and a reference wafer. In a further preferred embodiment, this assembly of wafers provides a hermetic barrier between the masses and an ambient environment.

  • Patent number: 7707590
    Abstract: An embodiment of the invention is directed to providing robust file system information for non-native devices. In operation, a file system includes both a file storage area for providing access to the contents of files, and a metadata store. The metadata store stores metadata associated with each file or device. When a device is connected to the file system, metadata for that device, and its items, is generated and stored in the metadata store. The metadata persists within the metadata store when the device is disconnected from, or no longer available to, the file system.

  • Patent number: 7441182
    Abstract: Systems and methods for digital negatives are described. In one aspect, a digital negative is created on a computing device from a digital image. The digital image is linked to the digital negative. In response to a save operation associated with the digital image, a new digital image is generated and bi-directionally connected to the digital negative. In response to a revert operation associated with the new digital image, contents of the new digital image are replaced with contents of the digital negative.
