Patent number: 11925435Abstract: An intra-oral scanning device includes a light source and an optical system, and communicates with a display system. The device provides for more efficient transmission and capture of images. It integrates OCT scanning with RGB-based scanning. In operation, the device is used for recording topological characteristics of teeth, dental impressions, or stone models by digital methods and for use in CAD/CAM of dental restorative prosthetic devices. To that end, the RGB-based scan obtains surface data (e.g., a margin), while the OCT scan penetrates the surface. The two scanners operate from within the same physical housing and preferably at the same time such that only one scanning pass (to obtain all necessary data) is required. The 3D data obtained from the OCT scan is registered with the 3D data obtained from the RGB-based scan by virtue of being captured using a common return path.Type: GrantFiled: June 9, 2022Date of Patent: March 12, 2024Assignee: D4D Technologies, LLCInventors: Ye Li, Justin G. Graham, Rod A. Duncan, Greg R. Basile, Grant E. Kenworthy, Henley S. Quadling, Mark S. Quadling, Glen Freeman

Patent number: 11846517Abstract: A method and system for generating geographic routes using topographic data that has been transformed into vector tiles to enable large spatial networks to be reduced from large scale to small scale, wherein the networks are reduced based on the lowest cost path(s) across each vector tile (for example, shortest, fastest and/or safest route across the represented geographic area) whilst ensuring connectivity between adjacent vector tiles is maintained. Complex and vast networks can be simplified to the cost of moving across a single vector tile from edge to edge, with each zoom level comprising a plurality of vector tiles with varying levels of detail concerning the paths across each vector tile. Routes between two locations, particularly those covering large distances, can then be quickly and efficiently determined using the processed vector tiles.Type: GrantFiled: April 13, 2021Date of Patent: December 19, 2023Assignee: Ordnance Survey LimitedInventors: Oliver Snowden, Mark Freeman

Patent number: 10561262Abstract: A lid assembly configured to close an opening in a vessel holding a liquid. The lid assembly includes a drinking port, plunger member, and drive assembly. The plunger member is moveable between closed and open positions with respect to the drinking port. The plunger member prevents the liquid from flowing through the drinking port when the plunger member is in the closed position and allows the liquid to flow through the drinking port when the plunger member is in the open position. The drive assembly includes drive circuitry that automatically directs the drive assembly to move the plunger member to the open position when the drive circuitry detects the lid assembly is in a drinking position. The drive circuitry automatically directs the drive assembly to move the plunger member to the closed position when the drive circuitry detects the lid assembly is in other than the drinking position.Type: GrantFiled: March 8, 2018Date of Patent: February 18, 2020Assignee: Pacific Market International, LLCInventors: Ping Phan, Evan Michael Choltco-Devlin, Naiqiang Zhang, Mark Freeman, Scott Jarnagin

Patent number: 10318669Abstract: For a time-series, a baseline error value is reduced to compute a target forecast error value by maximizing a net benefit value of a forecasted value of the time-series. For each forecasting model in a set of models, a corresponding model error value related to the time-series is computed. From the set, a subset of models is selected where each model in the subset has a cost that will produce a positive value for the net benefit. A selected model from the subset is associated with the time-series such that a model error value of the selected model is at most equal to the target forecast error. The time-series is forecasted using the selected model such that the forecasted value has an error of less than the baseline error at a future time, and the forecasted value produces a positive net benefit at the future time.Type: GrantFiled: June 16, 2016Date of Patent: June 11, 2019Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Mark A.

Patent number: 9896303Abstract: A method for controlling elevator cars of an elevator system according to one example includes assigning free elevator cars of the elevator system to one of either general service or express priority service (EPS). A destination dispatch controller receives an express priority service (EPS) call. The EPS call can indicate a request for priority service from an EPS call originating location to an EPS call final destination. The controller can determine whether any active EPS assigned car can service the EPS call. A particular elevator car can be an active EPS car when the particular car is carrying out EPS service. When a specific active EPS car can service the EPS call, the controller assigns the specific EPS car to the EPS call. Upon completion of the EPS call, the controller unassigns the EPS car to a free car.Type: GrantFiled: December 10, 2014Date of Patent: February 20, 2018Assignee: ThyssenKrupp Elevator CorporationInventors: Mark Freeman, Jennifer L.
