A method is for dynamically adjusting a circadian rhythm of an observer via a user device that includes control circuitry and an associated memory. The method includes determining a preconditioning schedule for at least one future event. Determining the schedule includes determining a preconditioning schedule for the at least one future events, including identifying a circadian shift needed, to the circadian rhythm of the observer, for the at least one future event, determining a timeframe for preconditioning, determining a per-day shift needed based upon the identified circadian shift needed and the determined timeframe, and determining if the needed per-day shift exceeds a threshold. Upon a determination that the per-day shift exceeds the threshold, the method includes setting the preconditioning schedule responsive to the determination to operate a light source to emit light based upon the preconditioning schedule.

The grounding clamp system is for use with an electrically insulated pole and for attachment to an electrical conductor in angled configurations. The grounding clamp system includes a clamping mechanism having an actuatable clamp and an associated ground conductor connector. An attachment coupler is configured to attach to the electrically insulated pole, and an angular adjustment mechanism is coupled between the clamping mechanism and the attachment coupler. The adjustment mechanism is configured to provide angular adjustment between the clamping mechanism and the attachment coupler in at least one axis while also transferring force to actuate the actuatable clamp when attaching the clamping mechanism to the electrical conductor at a selected angular position. The clamping mechanism is configured to create a path to pass ground fault current from the electrical conductor to a ground conductor coupled to the ground conductor connector without including the angular adjustment mechanism in the path.
