  • Patent number: 10023059
    Abstract: The present disclosure relates to automobiles and, more specifically, teaches methods and systems that may be used for wirelessly charging batteries used in vehicles. In one embodiment, a method for detecting a relative position between a vehicle-side receiving charging coil and a fixed transmission charging coil, may include: generating an alternating magnetic orientation field using one of the coils; detecting the orientation field using at least one coil provided for inductive excitation, wherein the orientation field is detected in a frequency-selective manner by the at least one coil; and ascertaining the relative position using an orientation receiving signal induced by the orientation field in the at least one coil.

  • Publication number: 20170136261
    Abstract: At least one laser line is projected onto a surface of a patient located on a patient table, and is detected. An evaluation and control apparatus determines initial coordinate points along a laser line projected onto the surface of the patient during an initial radiation procedure based on measurement values associated with the at least one laser line detected through an initial real-time triangulation process. The initial coordinate points are compared with target coordinate points for patient positioning. Whether or not an impermissible deviation exists between the initial coordinate points and the target coordinate points is determined, and a corrective action is executed based on the determination that an impermissible deviation exists. Determining updated coordinate points occurs while corrective action is being executed, and a warning signal is emitted based on the updated coordinate points.

  • Patent number: 9557158
    Abstract: A system and method for determining the position of objects in a radiation room for radiation therapy comprises several room lasers arranged in the radiation room, each of which is designed for patient positioning to project at least one laser line onto the surface of a patient located on a patient table in the radiation room. At least one camera detects at least one laser line projected onto the surface of the patient by at least one of the room lasers, and an evaluation and control apparatus determines the coordinate points along the laser line projected onto the surface of patient during a radiation procedure based on measurement values detected by the camera through a real-time triangulation process and compares them with target coordinate points. The coordinate points determined during the radiation procedure may be saved for documentation of the radiation procedure.
