Abstract: An improved article of footwear includes a midsole, an upper, and a support member. The midsole of the footwear contains a forefoot region, a heel region, a middle region. The midsole contains a medial recess and a lateral recess in the sidewall, and a central opening in the bottom surface, where the recesses and the central opening are in fluid communication with one another. The upper of the footwear is disposed on the midsole, but the bottom surface of the upper that is proximate to the central opening, the medial recess, and the lateral recess of the midsole is exposed. A support member is disposed on the bottom surface of the upper proximate to the central opening of the midsole. The support member is configured to extend from the bottom surface of the upper through the central opening of the midsole.

Abstract: A remote lock-out/tag-out system and method allow a remote service technician to remotely lock-out a machine via a remote wireless control device. In one aspect, the lock-out initiation request is sent from the remote wireless control device to the machine. The remote wireless control device then receives from the machine an indication that the machine location and state are suitable for lock-out. In response, the remote wireless control device sends a lock-out command to the machine.

Abstract: Provided herein are embodiments of a three-dimensional bicontinuous heterostructure, a method of producing same, and the application of this structure. The three-dimensional bicontinuous heterostructure includes two interpenetrating layers which are spatially continuous, include only protrusions or peninsulas, and have no islands. The method of producing the three-dimensional bicontinuous heterostructure includes forming an essentially planar continuous bottom layer of a first material; forming a layer of this first material on top of the bottom layer that is textured to produce protrusions for subsequent interpenetration with a second material, coating this second material onto this structure, and forming a coating with the second material that ensures that only the second material is contacted by subsequent layer. One of the materials includes visible and/or infrared-absorbing semiconducting quantum dot nanoparticles, and one of materials is a hole conductor and the other is an electron conductor.

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 bicontinuous 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: A method for removing impurities (e.g., atomic sulfur) from a reticle for use in photolithography is provided. In one embodiment, a reticle (or photomask) comprising a plate, a first layer over the plate, and a photoresist layer over the first layer is provided. The photoresist layer is removed with a first chemistry comprising a sulfur-containing compound. At least a portion of the first layer is removed with a second chemistry comprising a sulfur-containing etchant, thereby exposing portions of the plate. Removing the photoresist layer and/or at least a portion of the first layer leaves sulfur on at least portions of the reticle. In a cleaning step, the reticle is contacted with one or more excited species of oxygen to remove residual sulfur and other contaminants, such as carbon, sulfur and oxygen-containing species. Methods of embodiments can be used to clean, e.g., binary photomasks, attenuated phase shift masks (APSMs) and high transmission attenuated photomasks.

Abstract: An article of footwear is disclosed that includes an upper and a sole structure secured to the upper. The sole structure includes a connecting portion positioned adjacent the upper and extending along a longitudinal length of the upper. A plurality of discrete sole elements extend downward from the connecting portion. The sole elements define a lower surface, and the sole elements are separated by a plurality of sipes that extend upward from the lower surface and into the sole structure. An outsole may be located within the sipes or grooves and extend between the sole elements, with a lower portion of the outsole extending beyond the lower surface of the sole elements.
