    摘要： An instrument head for attachment to a plurality of instrument handles having different power sources is described. The instrument head includes at least one light-emitting diode, and a controller. When the controller detects an instability in a voltage input from a power source in an instrument handle attached to the instrument head, the controller transitions from a normal mode of operation to a mitigation mode of operation. The mitigation mode of operation prevents an increase in output of the at least one light-emitting diode for a predetermined period of time.

    摘要： An instrument head is provided for attachment to a plurality of instrument handles having different power profiles. The instrument head contains an illumination assembly including at least one LED as well as a drive circuit for detecting a power profile of an attached instrument handle and converting variable voltages received from the attached instrument handle to a constant current for powering the at least one LED based on the power profile. Accordingly, the instrument head enables use with a plurality of instrument handles, including those originally configured for use only with incandescent light sources.

    摘要： A physical assessment device includes an instrument head, an optical assembly and an adapter interface member. The instrument head includes an illumination assembly including at least one LED and a drive circuit for powering the at least one LED with a pulse width modulation (PWM) current to achieve a variable brightness of the at least one LED. The optical assembly includes a plurality of optical components disposed along an optical axis. The adapter interface member enables an image capture device to be attached to the instrument head and aligned with the optical axis. The image capture device is configured to capture images of medical targets when illuminated by the at least one LED. The drive circuit is coordinated with the image capture device to ensure that the medical targets are at least partially illuminated during the capturing of the images notwithstanding the variable brightness of the at least one LED.
