Abstract: A surgical light head and proximity detection method includes a housing, a plurality of light emitting elements arranged in the housing and configured to direct light at a target region of interest, and a plurality of distance sensors arranged in the housing. At least two of the distance sensors have field of views that overlap to define a common detection region of interest and the common detection region of interest at least partially overlaps with the target region of interest. The light head may have a plurality of integrally formed tilted seats that position the distance sensors relative to a center line of focus of the surgical light head. The distance sensors may be integrated in the housing via an optical component that is sealed relative to the housing and covers the distance sensor while enabling transmission and receipt of distance sensing signals therethrough.

Abstract: A system for identification of abnormalities related to illumination of a target and automatic compensation therefor includes a lighthead and a controller. The lighthead is configured to illuminate the target. The lighthead includes a plurality of lighting modules configured to emit light therefrom. Each of the lighting modules includes a distance sensor configured to measure a distance from the lighting module to a surface toward which the lighting module is pointed. The controller is configured to identify one or more abnormalities of the measured distances, determine a true distance from the lighthead to the target based on the measured distances, predict an amount of illumination based on the true distance that would be supplied to the target without the identified abnormalities, and compensate for the identified abnormalities by respectively adjusting an amount of light emitted from the lighting modules to illuminate the target according to the predicted amount of illumination.

Abstract: A surgical lighting system includes a central shaft, a surgical light head, an extension arm, a load balancing arm, and a yoke assembly. The extension arm is pivotably mounted to the central shaft. The load balancing arm is pivotably mounted to the extension arm. The yoke assembly supports the light head for multi-axis movement relative to the load balancing arm. The surgical light head includes a plurality of light emitting elements that are arranged to emit light downward to a region of interest and an optical signal generating component configured to capture data associated with the region of interest and generate an optical signal based on the captured data. Optical fiber cables and rotatable joints transmit the optical signal associated with the captured data from the surgical light head to one or more of the yoke assembly, the load balancing arm, the extension arm, and the central shaft.

Abstract: A method and apparatus for assigning addresses to components sharing a common bus. In one embodiment, an iterative elimination process is used to assign the addresses to each component. In another embodiment, each component includes a distance sensor that detects a distance to a front face of a calibration plank. Addresses are assigned to the components based upon the distance readings of the sensors.
