Apparatus and associated methods relate to an alignment system including an alignment source module (ASM) and an alignment indicator module (AIM) configured to be releasably coupled to a first unit and a second unit, respectively, of a pair of optoelectronic arrays. In an illustrative example, the ASM may be oriented, when coupled, to emit an optical beam in substantial alignment with a first optical axis of the first unit. The AIM may, for example, be configured, when coupled, to provide a visible indication when the optical beam is within a predetermined near-alignment orientation range relative to a second optical axis of the second unit. Each of the AIM and the ASM may, for example, be configured to axially couple along respective longitudinal axes of the first unit and the second. Various embodiments may advantageously facilitate manipulation of the pair of optoelectronic arrays into near alignment with each other.

The disclosure relates to rotary instrument indication systems. Also disclosed herein are rotary tools including indication systems. The indication systems can include a pressure sensor that can monitor force or pressured applied through a rotary instrument. A pressure indicator can also provide a feedback indication when the monitored force or pressure reaches or exceeds a predefined threshold. In some aspects, the rotary instrument is a dental drill.

There is disclosed a self-powered apparatus for measuring precipitation, comprising: a housing; a display unit including one or more display lights capable of displaying an amount of precipitation, wherein the display lights are formed on at least one of outer surfaces of the housing; a water collecting vessel, having a funnel-shaped space to which the precipitation is introduced and gathered at a vertex part of the funnel-shaped space; a cup module, having an accommodating space for accommodating the precipitation dropped from the vertex part of the funnel-shaped space of the water collecting vessel; an electric signaling unit; a guiding module; a self-powered generator; and a final drainage opening, formed at a lower part of the housing.

An example wear detection system receives first image data related to at least one ground engaging tool (GET) of a work machine from one or more sensors at a first time instance in a dig-dump cycle of the work machine. The wear detection system processes the first image data to determine a first wear measurement and first wear level for the at least one GET. The wear detection system determines whether the first wear level is indicative of a GET replacement condition. The wear detection system generates an alert when the first wear level is indicative of the GET replacement condition. The wear detection system receives second image data related to the at least one GET a second time instance different from the first time instance when the first wear level is not indicative of the GET replacement condition and determines a second wear measurement and second wear level for the at least one GET. The wear detection system generates an alert indicative of the first wear level and the second wear level based on determining that the first wear level and the second wear level are indicative of the GET replacement condition.

Apparatus comprises at least one visual indicator element; at least one detector to detect access to the apparatus consistent with a cleaning operation being applied to a surface of the apparatus; and processing circuitry to control a visual indication state of the at least one visual indicator element in response to a detection by the detector of access to the surface of the apparatus.
