  • Patent number: 12011239
    Abstract: An image-guided robotic intervention system (“IGRIS”) may be used to perform medical procedures on patients. IGRIS provides a real-time view of patient anatomy, as well as an intended target or targets for the procedures, software that allows a user to plan an approach or trajectory path using either the image or the robotic device, software that allows a user to convert a series of 2D images into a 3D volume, and localizes the 3D volume with respect to real-time images during the procedure. IGRIS may include sensors to estimate pose of the imaging device relative to the patient to improve the performance of that software with respect to runtime, robustness, and accuracy.

  • Patent number: 11501754
    Abstract: Desired vehicle destinations may be determined from spoken dialogs. A speech input may be received from a user through a voice user interface. Current utterance variables may be obtained by tokenizing the user speech input. One or more of a plurality of utterance templates for a reply to the user speech input may be determined by a trained automatic agent based on the plurality of current utterance variables. One of a plurality of Application Programming Interfaces (API) to call and one or more parameters for the API to call with may be determine by the trained automatic agent based on the plurality of current utterance variables. A response may be obtained from the API call. A context string for the reply to the user speech input by the trained automatic agent may be constructed based on the utterance templates and the response of the API call.

  • Publication number: 20190038387
    Abstract: An integrated dental porcelain system for making dental prostheses and restorations is provided. The system includes three universal major components: a) opaque porcelain composition; b) pressable dentin ingot; and c) veneering porcelain composition that can be used interchangeably for making restorations. Techniques for making the prostheses and restorations include porcelain fused-to-metal (PFM), press-to-metal (PTM), and either pressed and/or machined all-ceramic methods. The system uses both a hand-layering of veneering porcelain (PFM technique) and a hot-pressing process (PTM and all-ceramic technique) to fabricate the prostheses and restorations.

  • Patent number: 8775602
    Abstract: An alarm access controller is operative to control access to an enterprise network of a communication system responsive to alarms generated by products that are part of a set of internal resources of the enterprise network. In one aspect, the alarm access controller is implemented by a server or other processing element comprising a processor coupled to a memory. The alarm access controller is configured to receive an alarm from one of the products, to identify an external service provider for handling the alarm, and to provide temporary authenticated access of the service provider to the product. By limiting service provider access to an alarm-generating product in accordance with specified time periods or other conditions determined based at least in part on the alarm itself, system security is considerably improved and access control is made more flexible and efficient.
