Abstract: Disclosed are embodiments for providing temperature control for to a temperature-controlled storage compartment in a tunnel of a vehicle. The tunnel extends from a first side of the vehicle, such as the passenger side, to a second side of the vehicle, such as the driver side. The vehicle also includes a refrigeration module that is moveable on a shuttle of the tunnel. The refrigeration module includes a temperature-controlled storage unit configured to open and close in accordance with a path defined by an accessibility assembly. The shuttle transfers power from a power source, such as a battery, to the temperature-controlled storage unit, for example, to provide temperature control even when the vehicle is powered off. Accordingly, the refrigeration module provides a space-efficient system for ensuring prolonged temperature control of items stored in the temperature-controlled storage unit.

Abstract: An apparatus can include a door. The door can be configured to couple with a side of a vehicle. The door can include a step. The door can move the step.

Abstract: An electrical stimulation system includes a lead having electrodes disposed along a distal portion of the lead; and an implantable control module coupled, or coupleable, to the lead and configured for implantation in a patient. The implantable control module includes a power source, and a processor coupled to the power source and configured for directing electrical stimulation through the electrodes of the lead using the power source and for calculating an estimate of a capacity or energy of the power source that has been used based, at least in part, on the directed electrical stimulation.
