  • Patent number: 12003869
    Abstract: Systems and methods to track an object within an operating room with a camera unit. The camera unit includes a first optical sensor with sensing elements to sense light in a near-infrared spectrum and a second optical sensor to sense light in a visible light spectrum. A controller is in communication with the first and second optical sensors. The controller obtains, from the second optical sensor, data related to the object within the operating room. The controller modifies control of the sensing elements of the first optical sensor based on the data of the object obtained by the second optical sensor.

  • Publication number: 20240174081
    Abstract: A pedal unit for a vehicle has a sensor surface which includes at least two functional regions and is designed to detect an actuation by the driver. The pedal unit also has at least one evaluation and control unit coupled to the sensor surface and designed to evaluate an actuation of one of the at least two functional regions detected by the sensor surface and, as a function of this evaluation, control a vehicle function associated with the corresponding functional region of the sensor surface. At least one region of the sensor surface is raised or lowered and enables a haptic differentiation between the at least two functional regions of the sensor surface.

  • Publication number: 20240008933
    Abstract: Systems and methods for defining a relationship between a surgical object and a tracker coupled to the surgical object. A first optical sensor senses light in an infrared spectrum or a near-infrared spectrum. A second optical sensor senses light in a visible light spectrum. Controller(s) acquire one or more first images of the tracker from the first optical sensor and acquire one or more second images of the surgical object from the second optical sensor. The controller(s) recognize a pose of the tracker based on the one or more first image and recognize a geometry of the surgical object based on the one or more second images. The controller(s) correlate the recognized pose of the tracker and the recognized geometry of the surgical object to define a relationship between the tracker and the surgical object.

  • Patent number: 11806090
    Abstract: Systems and methods for calibration of a surgical tool having a tracker. At least one camera captures images of the tracker at a first exposure and captures images of the surgical tool at a second exposure with a different exposure time and/or illumination than the first exposure. Controller(s) recognize a pose of the tracker based on the first exposure images and recognize a geometry of the surgical tool based on the second exposure images. The controller(s) correlate the recognized pose of the tracker and the recognized geometry of the surgical tool to define a relationship between the tracker and the surgical tool and calibrate the surgical tool based on the defined relationship.

  • Patent number: 11723726
    Abstract: Systems and methods to track objects within an operating room with a navigation system that includes an optical sensor including sensing elements and a controller in communication with the optical sensor. The controller controls the optical sensor to process a first quantity of the sensing elements to view a first region of interest. The object is tracked within the first region of interest with the optical sensor. The controller obtains data related to the object within the operating room. The data may include a type of the object and/or prior pose data of the object being tracked. Based on the data, the controller controls the optical sensor to process a second quantity of the sensing elements, different from the first quantity, to view a second region of interest different from the first region of interest. The object is tracked within the second region of interest with the optical sensor.

  • Patent number: 11553970
    Abstract: A method, a controller, and a surgical hybrid navigation system for transferring a registration of three dimensional image data of a surgical object from a first to a second surgical navigation system are described. A first tracker that is detectable by a first detector of the first surgical navigation system is arranged in a fixed spatial relationship with the surgical object and a second tracker that is detectable by a second detector of the second surgical navigation system is arranged in a fixed spatial relationship with the surgical object. The method includes registering the three dimensional image data of the surgical object in a first coordinate system of the first surgical navigation system and determining a first position and orientation of the first tracker in the first coordinate system and a second position and orientation of the second tracker in a second coordinate system of the second surgical navigation system.

    Abstract: In accordance with the present invention, a method and apparatus that provides software products for installation on a user terminal is provided. The method begins by receiving over a communications network a user selection that includes a choice of a plurality of user-selected software products to be downloaded. In response to receipt of the user selection, an installation guide is assembled that includes installation instructions associated with each of the user-selected software products. A single user command is received over the communications network that includes a request to begin downloading the user-selected software products. In response to the request, the user-selected software products and the installation instructions are sequentially downloaded over the communications network to the user terminal. One or more of the software products may be configured to be automatically installed after they are downloaded.
