Patent number: 11872088Abstract: 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.Type: GrantFiled: January 20, 2021Date of Patent: January 16, 2024Assignee: American Sterilizer CompanyInventors: David A. Westenfelder, II, Jill A. Sanders, Michael Hollopeter, Joseph James Groszek, David Jesurun, Ian Hugh Cook

Publication number: 20230248248Abstract: A surgical lighting system includes a surgical lighthead including a lighthead housing including one or more light emitting elements therein that are arranged to emit light toward a region of interest. In some embodiments a temperature sensor is mounted to the lighthead housing and arranged such that it measures the temperature of a location in the region of interest. In other embodiments, a temperature sensor is external to the lighthead and configured to measure the temperature of a location in the region of interest. A controller is operatively coupled to the temperature sensor and configured to control temperature at the region of interest based at least in part on the temperature measured by the temperature sensor.Type: ApplicationFiled: February 10, 2023Publication date: August 10, 2023Inventors: James A.

Patent number: 11457994Abstract: A light head for a medical device support system. The light head includes first and second zones of light sources, an optical system, and a control system. The first and second zones of light sources emit respective first and second beams of light that form an illumination pattern having a pattern size at a region of interest. The optical system adjusts a beam spread of the second beam of light to change the pattern size of the illumination pattern from a first pattern size to a second pattern size. The control system varies power to the first and second zones of light sources in response to adjustment of the beam spread of the second beam of light to maintain a substantially constant magnitude of illuminance at the region of interest as the pattern size is changed from the first pattern size to the second pattern size.Type: GrantFiled: January 21, 2021Date of Patent: October 4, 2022Assignee: American Sterilizer CompanyInventors: David Jesurun, Benjamin L. Yoder

Patent number: 10363114Abstract: An aiming and status indicator system for surgical lightheads, cameras, and other lighting system accessory devices. The system includes a plurality of marker lights mounted to a housing for the accessory device. Each marker light produces a respective marker light beam that is directed towards a work area (surgical site) to provide a marker indicator pattern. The marker indicator patterns can be used to indicate the boresight of a lighthead or camera, whether a lighthead is in a focused or unfocused condition, and status information associated with the lighting system.Type: GrantFiled: October 19, 2017Date of Patent: July 30, 2019Assignee: American Sterilizer CompanyInventors: Michael Hollopeter, Damon Jurkiewicz, David Jesurun, Lena Tana Fogle

Patent number: 7321385Abstract: A surgical light system (10) includes a lighthead (44) coupled to a suspension arm (41?) adapted for mounting to a surface (14) of a surgical room. A bulb (130) is disposed in the lighthead. A processor (120) in the lighthead is operatively coupled with the bulb for controlling an intensity of light of the bulb and is adapted to generate a lighthead status signal representative of a first status of the lighthead. A control apparatus (32, 34) is in operative communication with the processor (120) in the lighthead. The control apparatus receives the lighthead status signal and selects a set of control algorithms from among a group of algorithms based on the lighthead status signal for controlling the lighthead.Type: GrantFiled: January 15, 2003Date of Patent: January 22, 2008Assignee: Steris Inc.Inventors: Steven H.

Patent number: 7191992Abstract: A medical suspension system (10) includes a ceiling plate (30) configured for mounting to a support structure (16). The ceiling plate supports a device (12), such as a lighthead or video monitor, which is mounted to the ceiling plate via an articulated arm (50) and a spindle (40), which is centrally mounted to the ceiling plate. A second device (14) is mounted to the ceiling plate, not through the spindle (40), in the conventional manner, but via an adapter plate (62), which is mounted directly to the ceiling plate. This increases the number of devices which are readily carried by the support structure without extending the spindle length which conventionally occurs when additional hubs are added to the main spindle.Type: GrantFiled: July 27, 2004Date of Patent: March 20, 2007Assignee: Steris Inc.Inventors: Jorg Wagner, Klaus Steger, Yury Keselman, David Jesurun, Roland D.
