Abstract: An electric vehicle solar charging system is disclosed, comprising a photovoltaic system or a DC source to transmit DC electricity to an electric vehicle via DC/DC conversion system. The DC/DC conversion is configured to directly transmit power to a battery pack configured to power the electric vehicle through the electric vehicle's DC charging inputs. This electricity can be supplemented by building battery or energy storage systems with DC output, or by DC electricity converted from AC which was supplied by AC sources. The combined circuit can be further modified by an in-line DC/DC converter at output if necessary, which also may be a bidirectional converter to supply energy from the EV back to the house load through a connected AC/DC inverter. When no DC is available, an AC power source can optionally provide supplemental power to the electric vehicle directly through the AC charging inputs.

An axially adjustable connection is used between the second receiving chamber and the proximal portion of the second shaft.

Abstract: Bidirectional or multidirectional cascading goals allow goal progress to roll up or downstream multiple levels in an organization. This means that goals from be assigned by higher-level employees to lower-level employees and lower-level employees to higher-level employees. The progress of contributing goals directly modifies the progress of all upward goals to reflect accurate progress of the overarching goal. Goals can be standalone goals, or contribute to other goals. A connection between goals may be made during the goal creation process or after both goals have been created.
