Abstract: A fuel cell system includes a fuel cell generator, a rechargeable energy storage circuit, an auxiliary load, a converter circuit, and a switch circuit. The fuel cell generator is operable to generate electrical power in a stack output signal. The auxiliary load is powered by the rechargeable energy storage circuit while in a first mode, and powered by a local signal while in a second mode. The converter circuit is operable to convert the stack output signal into a plurality of recharge signals while in the first mode and in the second mode, and convert the stack output signal into the local signal while in the second mode. The switch circuit is operable switch the plurality of recharge signals to one or more electric vehicles, and switch the local signal to the auxiliary load while in the second mode.

Abstract: Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient's body while maintaining insufflation.

Abstract: An agricultural device associated with reduced tillage techniques in a field includes a frame and a separator supported by the frame. The separator is configured to form a strip of exposed soil in residual plant matter in the field. A crimping device associated with the separator is configured to at least partially crush stems of residual plant matter while maintaining the strip.

Abstract: An agricultural device including a first frame portion rotatably carrying a second frame portion for carrying at least one agricultural module, the second frame portion being rotatable relative to the first frame portion between a first position generally perpendicular to a direction of travel of the device and a second position generally parallel to the direction of travel of the device, the first frame portion having a pair of rolling elements for supporting the first frame along a support surface. The pair of rolling elements is laterally movable relative to the first frame portion in a direction perpendicular to the direction of travel of the device. The pair of rolling elements continuously laterally surrounds the second frame when viewed from behind a forward direction of travel of the device.

Abstract: An agricultural device associated with reduced tillage techniques in a field includes a frame and at least one mower module supported by the frame, the at least one mower module positionable to cut plant matter between adjacent crop rows in the field. The plant matter has penetrated a previously formed mat of at least partially crushed residual plant matter.
