Abstract: A method of operating an exoskeleton system that includes obtaining a first set of sensor data from one or more sensors associated with one or more leg actuator units of an exoskeleton system during a user activity, the first set of sensor data indicating a first configuration state of the one or more actuator units; determining, based at least in part on the first set of obtained sensor data, to change configuration of the one or more leg actuator units to a second configuration state to support a user during the user activity; and introducing fluid to one or more fluidic actuators of the one or more leg actuator units to generate the second configuration state by causing the one or more fluidic actuators to apply force at the one or more actuator units.

Abstract: A process for producing ethanol wherein stillage is recycled into the process as a source of heat and power. Specifically, stillage is spray dried and then combusted in a biomass boiler. Spray drier exhaust is exported to the main scrubber and employed to extract particulates. Flue gas from the boiler is used to produce high pressure steam and the cooled gas is recycled back to the spray dryer as a heat source. The high pressure steam is used by a turbine generator which in turn produces electric power and low pressure steam both of which are returned to the process. Ash remaining after combustion may be used as a fertilizer.

Abstract: A beverage can compactor including an elongate compaction chamber for receiving emptied beverage cans. A pair of crushing platens are positioned for reciprocating movement from the opposite respective ends of the compaction chamber toward each other and then return to their initial positions at the respective ends of the compaction chamber. The compactor provides increased mechanical advantage at the beginning and end of the crushing stroke when such increased force is needed. Faster movement of the crushing platens is provided at the midpoint of the crushing stroke.
