A motor assembly includes a motor, a controller controlling at least one aspect of operation of the motor, and a control housing defining a control chamber. The controller is in part received within the control chamber. The controller includes a main electronics board and a modular connector assembly. The modular connector assembly includes a secondary electronics board and a connector at least in part supporting the secondary electronics board. The connector includes an inner connector portion and an outer connector portion. The connector extends through the control housing such that the inner connector portion is disposed inside the control chamber and the outer connector portion is disposed outside the control chamber. The outer connector portion defines a first access portal facilitating access to a first component of the secondary electronics board.

An earplug dispenser for contactless operation by a user having a container portion for receiving a plurality of earplugs. A dispensing portion is coupled to the container portion. The dispensing portion has a motor and a rotor coupled to the motor. The rotor has a plurality of rotor openings to receive individual earplugs in each rotor opening. The dispensing portion also has a dispensing opening. The motor rotates the rotor to dispense earplugs through the dispensing opening.

Control of an energy storage and provisioning system is disclosed, including a method in which electrical power is received from a power generator in an energy storage system having energy storage cells. Each of the energy storage cells has switching elements selectively operable to connect with terminals of other energy storage cells. The method further includes determining a condition of a number of the energy storage cells via electrical measurement; and grouping, by controlling operation of the switching elements, a subset of the energy storage cells into a topology configuration based on a condition of individual cells of the subset of energy storage cells. The method further includes storing the received electrical power into the subset of energy storage cells arranged into the topology configuration to optimize storage of the electrical power received from the power generator.
