Abstract: An apparatus includes one or more LEDs (304) configured to be coupled to a power supply (302) and to generate illumination, such as to generate a reticle (200) in an optical scope (104). The apparatus also includes a first switch (316) coupled in series with the one or more LEDs. The first switch is configured to selectively activate and deactivate the one or more LEDs based on whether the first switch is turned on or off. The apparatus further includes a low power detector (308) configured to sense a low power condition of the power supply and to repeatedly turn the first switch on and off in response to the low power condition to cause the one or more LEDs to blink. The low power detector is configured to turn the first switch on and off at a given rate, and the given rate increases as the power supply is depleted.

Abstract: An apparatus (100) for rotary encoding includes a knob (102) configured to be rotated. The apparatus also includes multiple switches (304, 402) each configured to selectively form or not form a connection based on a current rotational position of the knob. The apparatus further includes a controller (312) configured to generate or use a digital value associated with the current rotational position of the knob. The digital value is defined by which switches have or have not formed connections. Locations where the switches form the connections are selected such that the digital values uniquely identify different rotational positions of the knob and are non-sequential as the knob is rotated.
