Abstract: In some implementations, a device may receive, from one or more programmable components disposed in a changeable tip of an imaging device, a signal indicating tip configuration information associated with the removable tip. The device may activate software that causes one or more processors to configure, based on the tip configuration information, at least one testing parameter associated with a test to inspect an image of an end face of an optical fiber for compliance with a set of criteria related to a condition of the end face of the optical fiber. The device may output a result of the test that indicates a compliance status associated with the set of criteria.

Abstract: Some implementations include a changeable tip of a microscope system for testing an end face of an optical fiber. The changeable tip may include a tip housing having an optical fiber interface at a first end of the housing and configured to be coupled with the end face of the optical fiber and a device interface configured to be coupled with a tip connection interface of an opto-mechanical assembly of the microscope system. The changeable tip also may include at least one tip orientation indicator associated with the tip housing and configured to interact with a tip connection interface of the opto-mechanical assembly to cause a signal indicating tip orientation information associated with the changeable tip to be provided to the imaging device.

Abstract: An electrostatic fluid accelerator includes an electrode array including an array of corona discharge electrodes and an array of accelerating electrodes. A detector is configured to sense a constituent component of the fluid as present in an output from the electrode array. A control circuit supplies power to the electrode array, the control circuit being responsive to an output from the detector for operating the electrode array responsive a level of the constituent component.
