A system for repositioning teeth a patient from an initial tooth arrangement to a final tooth arrangement includes a plurality of incremental position adjustment appliances, each having an arrangement of cavities shaped to receive and reposition teeth of the patient. The cavities in at least one appliance in the system have a different geometry than that of at least one other appliance in the system. At least some of the appliances in the system are successively worn by the patient to exert force on at least one tooth and move the teeth of the patient from a first arrangement to a successive arrangement different from the first arrangement. The system includes a first multilayer shell with a bending stiffness factor less than about 0.1 GPa*mmand an elastic modulus no greater than about 1.5 GPa; and a second shell with a bending stiffness factor greater than 0.1 GPa*mm.

This disclosure relates generally to methods and systems for determining whether at least a first component and a second component of a personal protection (PP) configuration are compatible so as to be assembled into an approved PP configuration, responsive to being compared against at least one predetermined criterion. Included is a smart tag for each of the first and second components. The first and second smart tags include respective first and second data. A data acquiring system is provided for acquiring the first and second data and a data processing system processes the acquired first and second data for determining if the first and second components are compatible to be assembled as an approved PP configuration.

A 3D imaging apparatus with enhanced depth of field to obtain electronic images of an object for use in generating a 3D digital model of the object. The apparatus includes a housing having mirrors positioned to receive an image from an object external to the housing and provide the image to an image sensor. The optical path between the object and the image sensor includes an aperture element having apertures for providing the image along multiple optical channels with a lens positioned within each of the optical channels. The depth of field of the apparatus includes the housing, allowing placement of the housing directly on the object when obtaining images of it.

The present invention relates to various methods of collecting and using data from RFID tags associated with items of interest. In one embodiment, the permissible error tolerance associated with the location of an RFID-tagged item may be altered, either manually or automatically. In another embodiment, RFID-tagged items may be associated with certain categories of items, based either on default or user-specified categories.
