  • Non-welded horizontal cable tray redirector
    Patent number: 11936172
    Abstract: Improved design of cable tray redirector components speeds assembly and connection of cable trays. More efficiently manufactured, universal components needed throughout horizontal redirectors of a specific size and type cable tray run reduce the overall total items and cost of inventory. The improvement is in part the elimination of welding cable redirector components in favor of connecting the components with bolts and nuts in the field. The inventory and shipment of individual parts is substantially more efficient because the new components “nest” efficiently prior to assembly. Moreover, components are designed to minimize the number of bolts and nuts used without jeopardizing strength. The use of bolts and nuts to fasten the components also enables good electrical conductivity for effective electrical grounding of the assembled cable tray system.

  • METHOD OF DESIGNING AND FABRICATING PATIENT-SPECIFIC RESTORATIONS FROM INTRA-ORAL SCANNING OF A DIGITAL IMPRESSION COPING
    Publication number: 20240078674
    Abstract: Taking a digital implant or abutment level digital impression by means of intra-oral, computed tomography or other imaging method provides the restorative doctor and laboratory accurate and effective data for determining the implant position, angulation and locking feature orientation without a physical impression. Such data is correlated with a digital library to produce an output which enables design and fabrication of an accurate restorative device such as a prosthetic tooth or crown. In this way the time-consuming, costly and error prone mechanical replication of the relevant dental anatomy is obviated.

  • System and method for performing quality control of manufactured models
    Patent number: 11915403
    Abstract: Disclosed herein are example embodiments of methods and systems for identifying manufacturing defects of a manufactured dentition model. One of the methods for performing quality control comprises: determining whether the manufactured dentition model is a good or a defective product based on a statistical characteristic of a differences model. The differences model can be generated based on differences between a scanned 3D patient-dentition data and a scanned 3D manufactured-dentition data. The scanned 3D patient-dentition data can be generated using 3D data of a patient's dentition, and the scanned 3D manufactured-dentition data can be generated using 3D data of the manufactured dentition model. The manufactured dentition model can be a 3D printed model.
