Dual input voltage constant power indicator

Apparatus and associated methods relate to a dual-input voltage range compatible light adapted to reconfigure two light elements in series or in parallel and make corresponding current limit adaptations, in response to the input voltage entering one of two predetermined ranges. In an illustrative example, the lighting elements may be strings of LEDs. The current limit may be regulated, for example, by two linear current regulators. In various examples, the current through each of the light elements may be maintained at a predetermined current level independent of the input voltage range.

Some apparatus and associated methods relate to conductivity modulation apparatus for active operations with an inductive element in a packaged circuit module formed with a bypass switch for configuration in parallel with an inductor. In

Apparatus and associated methods relate to a photoelectric sensor system with a primary photo-detector to receive an on-axis return reflected by a retro-reflective target, and a monitor photo-detector to detect off-axis light indicative of a

Apparatus and associated methods relate to dual safety touch button systems for generating machine operation commands, according to predetermined safety guidelines, from status information received via an intercommunications link (ICL) operably connecting the dual safety
