A device to allow a two-way switch to be used in an electrical circuit comprising multiple switches. Using the invention device, the two-way switch can operate as either a three-way switch or a four-way switch in a multiple-switch electrical circuit using AC mains voltage.

Device to allow a two-way switch to operate in a multiple-switch electrical circuit

A system, device and method to allow communications between switches in an electrical circuit containing three-way and four-way switches. The system, device and method allow any switch in an electrical circuit using conventional wiring for three-way and four-way switches to indicate when voltage is being supplied to the electrical load device in the electrical circuit; if a dimmer is present in the electrical circuit, to indicate the dim level of the load device in the electrical circuit and to command to dim level from any switch; and if a timer is present, to allow any switch to provide a warning indication prior to the timer shutting off the load device, and to allow any switch to reset the timer, preventing the shutoff.

Communications in multiple-switch electrical circuits

A document production system is provided for preparing documents and managing a database of information pertaining to investigational studies of medical products. The document production system includes a data management user interface for providing user access to the database and for retrieving information from the database as specified by selected document templates for placement into word processor-compatible documents. Additionally, the data management user interface is capable of updating information stored within the database in accordance with information specified within a previously-prepared document.

Drug document production system

An apparatus for merging real and virtual images in which points in three dimensions of an actual scene are obtained and selected in a random fashion and in a number sufficient to track the movement of the three dimensional scene relative to an observer wearing the apparatus. Updating of selected points occurs responsive to movement of a video camera pair observing the actual scene. The position and orientation of the unit housing the video camera pair is utilized to properly merge a generated virtual image with the real image. Selection of points and orientation of the unit relative to a three dimensional real image are obtained in real time. Microprocessor-based apparatus is utilized to perform the method of the invention.
