20090199669 | EXTERNAL GEAR SHIFT FOR A MANUAL TRANSMISSION - An external gear shift for the gear selection in a manual transmission is provided that includes, but is not limited to a gearshift/selector lever, which is guided in a link plate and which is movable along a selector track and a plurality of shifting tracks, and a measuring sensor to detect an instantaneous position (s, w) of the gearshift/selector lever. Guide fingers of the link plate disposed between shifting and selector tracks each have flanks oriented obliquely to the shifting and selector tracks. | 08-13-2009 |
20090204300 | SHIFTING DEVICE FOR A MANUAL TRANSMISSION - A shifting device is provided for the gear selection in a manual transmission that includes, but is not limited to a shift/selector lever that can be moved in a shifting degree of freedom and a selection degree of freedom, a measuring sensor for measuring a current position (s, w) of the shift/selector lever in the two degrees of freedom, a two-dimensionally controllable actuator device and a control circuit for the controlling of the actuator device in a position (S, W) which is associated with the sensed position (s, w) of the shift/selector lever, which depicts the movement region of the shift/selector lever on a region of possible positions of the actuator device. The movement region of the shift/selector lever included, but is not limited to a two-dimensional prohibited part region, in which the shift/selector lever is simultaneously moveable in both degrees of freedom. The control circuit depicts this prohibited part region on positions on an edge of the region of the possible positions of the actuator device. | 08-13-2009 |

20090078568 | ON-DEMAND HYDROGEN GAS GENERATION DEVICE HAVING GAS MANAGEMENT SYSTEM - The present disclosure generally relates to an on-demand hydrogen gas generation device, suitable for use in a fuel cell, which utilizes water electrolysis, and more particularly galvanic cell corrosion, and/or a chemical hydride reaction, to produce hydrogen gas. The present disclosure additionally relates to such a device that comprises a switching mechanism that has an electrical current passing therethrough and that repeatedly and reversibly moves between a first position and a second position when exposed to pressure differential resulting from hydrogen gas generation, in order to (1) alter the rate at which hydrogen gas is generated, such that hydrogen gas is generated on an as-needed basis for a fuel cell connected thereto, and/or (2) ensure a substantially constant flow of hydrogen gas is released therefrom. The present disclosure additionally or alternatively relates to such an on-demand hydrogen gas generation device that comprises a gas management system designed to maximize the release or evolution of hydrogen gas, and in particular dry hydrogen gas, therefrom once it has been formed, thus maximizing hydrogen gas output. The present disclosure is still further directed to a fuel cell comprising such an on-demand hydrogen gas generation device, and in particular a fuel cell designed for small-scale applications. | 03-26-2009 |
20090081497 | ON-DEMAND HIGH ENERGY DENSITY HYDROGEN GAS GENERATION DEVICE - The present disclosure generally relates to an on-demand hydrogen gas generation device, suitable for use in a fuel cell, which utilizes water electrolysis, and more particularly galvanic cell corrosion, and/or a chemical hydride reaction, to produce hydrogen gas.
