Abstract: Embodiments of the present disclosure generally relate to a pivoting assembly, to tools including the pivoting assembly, and to their methods of use in, e.g., collecting lunar samples. One embodiment comprises a shaft coupled to a handle at one end and coupled to a pivoting assembly at the opposite end. The pivoting assembly may comprise a slotted axle, a locking rod having a head engageable with a slot of the slotted axle, and a release handle coupled to the locking rod. The release handle is movable to move the head of the locking rod into a locked position and an unlocked position. A rotatable arm is coupled to the pivoting assembly and is rotatable relative to the handle when the head of the locking rod is in the unlocked position.

Abstract: Methods and systems that provide personal, educational, and career analytics for students to navigate the ever increasing educational and career landscape. Instant simulated journeys of success may be created by translating personal, educational, and career data into visual and navigational choices for every student and parent. Users may be allowed instant access to all K1-to-K20 personalized education records in order to continually analyze that data against the labor market, labor data, personal interests, and educational choices and job forecasts in order to produce continual options and validation. Results may be produced that help students and parents more accurately prepare and plan by visually seeing progress, strengths, weaknesses, funding needs, options and statistics on a regular basis.
