In preferred embodiments, the system described herein will accommodate light source tracking for multiple surgeon-worn devices worn by one or more wearers. The system is capable of toggling between modes of following the wearer's movement and focusing on a single point determined by the wearer, where mode swapping can be controlled by the surgeon from the device itself. The system preferably accommodates the adjustment of multiple characteristics of the light source, such as light intensity, from the hand or wrist device. A periphery ribbon may also be used to control the direction of light sources. Applications of the invention y stretch to other fields such as construction or theater lighting. ## Claims ### Claim 1 A system for providing light in an operating room, comprising: a plurality of pan/tilt articulating light sources; a pair of wireless receivers, each capable of receiving a wireless signal in the radio frequency spectrum; at least one wearable transmitting device capable of emitting said wireless signal from a target location; and at least one controller operatively coupled to said one or more pan/tilt articulating light sources for articulating said pan/tilt articulating light sources to provide a coordinated beam of light aimed at said target location, said controller being in communication with said wireless receiver and including software stored on non-transitory computer media and configured to triangulate said target location based on differential signal characteristics of the wireless signal received at said pair of wireless receivers. ### Claim 2 (depends on 1) The system of claim 1, wherein said at least one wearable transmitting device comprises two or more wearable devices each capable of, emitting a unique wireless signal. ### Claim 3 (depends on 2) The system of claim 2, wherein said controller is programmed to pair each of said plurality of pan/tilt articulating light sources with a single one of said two or more wearable devices based on the unique wireless signal emitted by each of said wearable devices. ### Claim 4 (depends on 2) The system of claim 2, wherein said software is configured to pair each of said plurality of pan/tilt articulating light sources with a nearest one of said two or more wearable devices based on the target location of each of said wearable devices as calculated by said software. ### Claim 5 (depends on 2) The system of claim 2 wherein said at least one controller further includes software configured to calculate a desired beam intensity of said plurality of pan/tilt articulating light sources to provide a desired illumination strength for said light sources, and to adjust said beam intensity of said plurality of pan/tilt articulating light sources. ### Claim 6 (depends on 5) The system of claim 5, wherein said at least one controller is configured to receive voice commands to adjust said beam intensity of said plurality of pan/tilt articulating light sources. ### Claim 7 (depends on 2) The system of claim 2, wherein said at least one controller is configured to operate said plurality of pan/tilt articulating light sources according to a “set” mode or a “follow” mode, wherein a position of said plurality of pan/tilt articulating light sources is fixed when placed in “set” mode. ### Claim 8 (depends on 7) The system of claim 7, wherein said at least one controller is configured to operate some of said plurality of pan/tilt articulating light sources in one of “set” or “follow” mode and others of said plurality of pan/tilt articulating light sources to be selectable between “set” mode and “follow” mode. ### Claim 9 (depends on 7) The system of claim 7, wherein each of said wearable transmitting devices includes a switch to toggle an operating mode of said controller between “set” mode and “follow” mode. ### Claim 10 (depends on 7) The system of claim 7, wherein said at least one controller is configured to receive voice commands to switch an operating mode of said at least one controller between “set” mode and “follow” mode. ### Claim 11 (depends on 2) The system of claim 2, wherein said at least one wearable transmitting device is are configured to be worn around a human wrist. ### Claim 12 (depends on 2) The system of claim 2, wherein said at least one wearable transmitting device is configured to be worn around a human finger. ### Claim 13 (depends on 2) The system of claim 2, further comprising a driver operatively connected between said controller and said plurality of pan/tilt articulating light sources. ### Claim 14 (depends on 2) The system of claim 2, wherein said plurality of pan/tilt articulating light sources are mounted in an enclosure in a ceiling of an operating room. ### Claim 15 (depends on 2) The system of claim 2, wherein said at least one transmitting device is a ribbon-type device, said target location is a location of said ribbon-type device, and wherein said controller includes means to triangulate said target location based on differential signal characteristics of the wireless signal received at said pair of wireless receivers. ### Claim 16 (depends on 15) The system of claim 15, wherein said at least one ribbon-type device is capable of being manipulated into a position surrounding a surgical area as an outside border.
