Abstract: A method for designing and manufacturing implant based restorations is disclosed. The method involves the use of Scannable Temporary Anatomic References to provide very reliable, fixed points of reference to enable a technician to relate and superimpose the dental implant position to a pre-planned restoration with a very high degree of accuracy throughout the entire workflow. The method can be carried out by placing Scannable Temporary Anatomic References in a jaw, on teeth, and/or in implants, collecting images by scanning a mouth, relating those images to images of a appearance of desired dental implant based restoration, placing an implant in the jaw, scanning the scannable temporary anatomic references to create a new set of images, relating the images, and producing a restoration based on the images.

Abstract: An entity is made the target of a communication—such as instant messaging, E-mail, or VoIP—based on a specification of context that the entity satisfies. A user (or other type of entity) who wishes to communication with one or more entities that satisfy a particular context specifies that context at the time the communication is to be sent. A system resolves the context by ascertaining which one or more entities satisfy the context, and the communication is sent to the ascertained entities. In one example, a user can specify that a message is to be sent to an entity at a particular geographic location, and the system chooses the one or more entities that are nearest to the specified location.

Abstract: A transient electromagnetic signal transceiver for use in geophysical prospecting includes cultural noise and random noise reduction features. AC mains interference signals are minimized by synchronizing the reception of TEM signals with the mains frequency so that the mains interference components of alternate TEM signal measurements cancel. Other cultural noise is minimized by using low pass filters tuned to reject VLF radio signals. Common mode signal rejection, sferics suppression and signal stacking and averaging techniques improve the signal-to-noise ratio of the received TEM signals, while the use of a programmed microprocessor enables overall control of the transceiver to include the calculation and presentation of ground conductivity and other data.
