A sterilizable cover for a handle of an accessory of a medical suspended ceiling assembly includes a generally tubular stem portion and an annular flange portion. The generally tubular stem portion has a sufficient size to be gripped by the human hand, and has a proximal end that is open and a distal end that is closed, and defines a cavity along a longitudinal axis for receipt therein of a handle grip portion. The generally tubular stem portion includes a friction fit portion that is configured to flex radially outwardly to create a friction fit with a portion of the handle grip portion upon receipt of the handle grip portion in the cavity of the generally tubular stem portion. The annular flange portion extends radially outwardly from a proximal end of the generally tubular stem portion. The generally tubular stem portion and the annular flange portion are a single continuous piece of flexible silicone rubber.

A load balancing arm for a medical device support system includes a proximal hub, a support arm, a link, and a distal end vertical block. The components together may form a four bar linkage. The proximal hub is configured for pivotable movement about an axis P-P. The distal hub is configured to support a medical device load for pivotable movement about an axis D-D. The distal hub is mounted to the distal end vertical block for pivotable movement between a first position in which the axis D-D is at a first angle relative to the axis P-P and a second position in which the axis D-D is at a second angle relative to the axis P-P, wherein the first angle is different than the second angle. A parallelism adjustment mechanism enables the axis D-D to be adjusted so as to be substantially parallel to the axis P-P.

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.

A device and method for operating a lighting system varies a characteristic of visible light emitted by a first lighthead according to a predefined profile, and fixes a characteristic of visible light emitted by a second lighthead. A light sensor configured to view a focal area of the second lighthead detects a characteristic of visible light on a target surface over a period of time, and the characteristic of the light detected by the light sensor over the period of time is compared to the characteristic of light defined in the predetermined profile. A mode of operation of the first and second lighthead is determined based on the comparison.

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.
