Abstract: Disclosed herein are systems and methods that include a keypad that detects button presses using deflection sensing. The keypad may be a keypad of a camera such as an endoscopic camera head. A button press may be detected based on an amount of deflection of a material. The deflection of the material may be caused by force from a user's finger on a button of the keypad. The material may be located proximate to a sensor, which outputs a sensor signal indicating the amount of deflection of the material. Aspects of the disclosure comprise a controller that identifies an amount of deflection, compares the amount of deflection to a signal threshold, and determines whether a button has been pressed based on the comparison.

Abstract: Described herein are light sources for illuminating a target for medical imaging, the light source comprising: a first light emitter package comprising a first light emitter that emits light having a first wavelength band and a second light emitter that emits light having a second wavelength band that is different than the first wavelength band; a second light emitter package comprising a third light emitter that emits light having a third wavelength band that is different than the first and second wavelength bands; and a controller for operating the light source in a first mode in which the first light emitter and the third light emitter are activated and the second light emitter is deactivated, and a second mode in which the first light emitter is deactivated and the second light emitter is activated.

Abstract: A method for defogging an optical component of an endoscope includes operating an illuminator in an imaging mode in which the illuminator generates illumination light for endoscopic imaging of a target, wherein at least a portion of the illumination light is generated by a light source that generates light having a first waveband at an imaging intensity level; and changing the operating mode of the illuminator from the imaging mode to a defogging mode in which an intensity level of the light having the first waveband is increased from the imaging intensity level to a defogging intensity level to warm and defog the optical component of the endoscope.

Abstract: A method for medical imaging, the method including receiving light from a scene at a camera assembly that comprises at least one reflecting optical element and an imaging sensor assembly; reflecting light received by the camera assembly from the scene toward the imaging sensor assembly via the at least one reflecting optical element, wherein reflecting the light causes the scene to be at least one of inverted and reverted at the imaging sensor assembly; focusing the reflected light onto the imaging sensor assembly with at least one focusing optical element; transmitting image data generated from the focused light from the imaging sensor assembly to a camera controller; and generating by the camera controller a non-inverted and non-reverted image of the scene from the data generated by the imaging sensor assembly.
