Abstract: The present invention provides of a three-dimensional bicontinuous heterostructure, a method of producing same, and the application of this structure towards the realization of photodetecting and photovoltaic devices working in the visible and the near-infrared. The three-dimensional bicontinuous heterostructure includes two interpenetrating layers which are spatially continuous, they are include only protrusions or peninsulas, and no islands. The method of producing the three-dimensional biontinuous heterostructure relies on forming an essentially planar continuous bottom layer of a first material; forming a layer of this first material on top of the bottom layer which is textured to produce protrusions for subsequent interpenetration with a second material, coating this second material onto this structure; and forming a final coating with the second material that ensures that only the second material is contacted by subsequent layer.

Abstract: A system and method for remotely controlling an increased number of subsystems having an onboard locomotive control unit (LCU) and two associated operator control units (OCUs) on a single wireless channel. A time slot is assigned to each subsystem for making two-way transmissions to control the locomotive. A signal from an external timing source synchronizes each subsystem to minimize interference between transmissions from different subsystems. Time slots are assigned manually or automatically over a wireless network or by the LCU after monitoring the channel. The LCU automatically selects the direct or repeater transmission path depending upon whether or not it receives polling message responses from its associated OCUs. A GPS receiver in each subsystem receives the synchronization signal and provides geographic positioning data so the LCU can determine when to execute predefined, position-based commands. The secondary OCU may be turned off and rejoined to the subsystem without ceasing operation.

Abstract: An athletic water sports shoe. The water sports athletic shoe features a rubber outsole for a strong grip on wet surfaces. In addition to the rubber outsole, a rubber rand extends the rubber surface to the sides of the shoes such that sides of the wearers foot can be used as gripping surfaces. The sides of the shoes are constructed of a waterproof mesh that allows water to flow in and out of the shoe. The inside of the shoe features a neoprene gasket that forms a water-tight seal around the ankle of the wearer. The water-tight seal around the ankle of the wearer prevents sand from entering the shoe. Furthermore, the neoprene gasket protects the foot from bumps and scrapes.
