International Classification:

G06F 3/00

US Classification:

715752, 715758, 715855

Abstract:

The present invention provides a user interface that includes a first column for chronologically displaying a set of messages (objects) in a conversation, and a second column for displaying a branch of messages (objects) corresponding to a message (object) selected in the first column. The user interface further includes, among other things, a list of participants to the conversation, a vertical index (time line), a list of related conversations and a conversation map that illustrates a hierarchy of the conversation. Each message (object) in the first column can have an associated indicator for indicating a quantity of predecessors and successors to the set of messages (objects), as well as an in-line reply button for replying to the set of messages. Each of the messages displayed of the second column can have one or more associated navigation buttons for navigating adjacent hierarchical levels.

Abstract:

Disclosed herein are systems and methods for providing personalized oral irrigation. One variation of a method of generating a model of an oral insert including a fluid inlet port, fluid nozzles, manifolds, and a tray configured to retain teeth may comprise the steps of displaying a graphical representation of the oral insert model, generating a geometry of the fluid nozzles based on oral scan data of a jaw, defining a tray surface that encloses the fluid nozzles based on the oral scan data, generating a geometry of the manifolds that connect the fluid inlet port to the fluid nozzles on the graphical representation of the oral insert model. The manifolds are configured to provide a predetermined range of hydraulic pressures to each of the fluid nozzles.

Abstract:

A computer process for fitting construction materials to an architectural surface modeled in CAD divides the surface into domains, and defines sample points on each domain surface. Low accuracy then high accuracy iterations match a domain to a surface portion of a regular curved solid. The low accuracy match limits the type and orientation of the curved solid. The high accuracy match derives a central reference for the curved solid by defining vector pairs from among the sample points and calculating multiple resultants as cross products of vector pairs that share a common origin. Reference points are located wherever the distance between any two resultants is minimum, and the central reference, e.g. an axis, is derived from the reference points using regression analysis. The match to the domain may be iteratively improved by adjusting a parameter such as a radius until a desired accuracy is achieved. The result is compared to stored specifications to identify construction materials capable of forming the domain. Parallel processing may be employed to reduce time for solving fitting problems for large architectural projects having multiple surfaces with complex curvatures.
