    Abstract: The present disclosure provides identification techniques on platinum group metal (PGM) and zero platinum group metal (ZPGM) catalyst systems, in order to identify responsible materials for the formation of corrosion products, such as hexavalent chromium compounds. Identification analyses, such as X-ray diffraction analysis (XRD) and X-ray fluorescence (XRF) may be performed on various thermally treated PGM and ZPGM catalyst systems. Results of identification analyses may show that for both PGM and ZPGM catalysts, hexavalent chromium (Cr6+) may be formed during thermal aging at range of 600C to 900C. This may be due to the high concentration of chromium in substrate alloys. Therefore, occurrence of corrosion and production of hexavalent chromium may initiate from elements found in the substrate and not from elements within the PGM and ZPGM catalysts.

Nitric acid groups are bonded to hydrophilic groups (sulfonic acid groups) contained in a reaction layer for fuel cells, and metal ions capable of forming a nitrosyl complex with the nitric acid groups, e.g., ruthenium ions, are introduced into the reaction layer to dye the nitric acid groups bonded to the hydrophilic groups contained in the reaction layer. When the hydrophilic groups have agglomerated, the nitric acid groups bonded thereto also agglomerate. When said nitric acid groups are dyed with ruthenium, the ruthenium also agglomerates to make it possible to examine said nitric acid groups with an electron microscope.

    Abstract: Sensors for sensing/measuring one or more analytes in a chemical environment. Each sensor is based on a semiconductor structure having an interfacial region containing a two-dimensional electron gas (2DEG). A catalyst reactive to the analyte(s) is in contact with the semiconductor structure. Particles stripped from the analyte(s) by the catalyst passivate the surface of the semiconductor structure at the interface between the catalyst and the structure, thereby causing the charge density in the 2DEG proximate the catalyst to change. When this basic structure is incorporated into an electronic device, such as a high-electron-mobility transistor (HEMT) or a Schottky diode, the change in charge density manifests into a change in an electrical response of the device. For example, in an HEMT, the change in charge density manifests as a change in current through the transistor, and, in a Schottky diode, the change in charge density manifests as a change in capacitance.

  • Patent number: 8554960
    Abstract: In an input device, a controller for controlling an input portion and acquiring data is connected to a bus. The bus can be connected with an external expansion device via an expansion connector. The connection of the bus from the expansion connector to the controller is switched on and off by a switcher. Data acquired from a sensor having a function equivalent to that of the external expansion device is transmitted to the controller via the bus by a sensor controller which is connected to each of a side of the controller and a side of the expansion connector of the bus without interposing the switcher. The sensor controller switches the connection of the switcher off when an access to itself is made from the controller.

  • Patent number: 8506369
    Abstract: Various systems, game controllers, and methods for simulating various objects such as weapons are provided. For example, a game controller may include a trigger, a processor within the body that receives a trigger signal when the trigger is activated by the user. The processor may communicate with a computer running a software program such as a gaming application, and an actuator coupled to the trigger, the actuator configured to output a haptic effect to the trigger in response to receiving a control signal from the processor. The game controller may simulate a gun and generate a recoil effect. In some embodiments, the recoil effect may be generated by impacting a moving mass from a discharge end of the gun to a handle end of the gun. In some embodiments, the recoil effect may be generated by using a body part of a user as a tether.

  • Publication number: 20130059390
    Abstract: Aspects of the invention relates to a system and method for determining the efficacy of the catalyst comprising means to detect any temperature change in the catalyst when oxygen is present in the anaerobic workstation and determine the efficacy of the catalyst in accordance with the temperature change. A detectable rise in the temperature of the catalyst is indicative of a catalytic reaction to remove oxygen from the anaerobic work station. Thus, the system determines the catalyst is an active catalyst if the temperature of the catalyst rises when oxygen is present in the anaerobic workstation. The system determines the catalyst is an inactive catalyst if the temperature of the catalyst does not rise when oxygen is present in the anaerobic workstation. Further aspect of the invention relate to a system and method for determining the atmosphere of an anaerobic workstation in accordance with the efficacy of the catalyst of the anaerobic workstation.
