| 20090235627 | ELECTRONIC ENGINE SPEED CONTROL SYSTEM FOR GRASS MOWING MACHINE - An electronic engine speed control system for a grass mowing machine powered by an internal combustion engine includes a microcontroller providing an output signal to an engine speed actuator for the engine, a pedal position sensor connected to a foot pedal and providing a voltage input signal to the microcontroller based on the position of the foot pedal, a PTO clutch switch providing a signal input to the microcontroller indicating if a PTO clutch is engaged, and a lever position sensor connected to a hand lever and having a range of positions including an Automatic mode position and a plurality of Manual mode positions. The hand lever position sensor provides a voltage input signal to the microcontroller in the Automatic mode position such that the microcontroller output to the engine speed actuator is related to the voltage inputs from the pedal position sensor and PTO clutch switch, and provides a voltage input signal to the microcontroller in a range of Manual mode positions such that the microcontroller output to the engine speed actuator is related to the voltage input from the lever position sensor. | 09-24-2009 |

| 20090230107 | POSITIONING ATTACHMENT FOR A WELDING TORCH - A positioning attachment for definition of torch angle and torch to workpiece distance during welding and/or training is provided. The positioning attachment includes one or more legs of equal or varied lengths capped with a tip, which contacts the workpiece, and a body, which may be permanently attached or removably secured to the welding torch nozzle. Certain embodiments may be made of heat resistant metals or ceramic to withstand high temperatures during welding. The positioning attachment may be mounted on the welding torch nozzle or provided as an extension of the contact tip. | 09-17-2009 |

| 20110247246 | ATTACHMENT CUTTING SYSTEM HAVING CUTTING HEADS AND A CUTTER CHAIN - The invention relates to an attachment cutting system having an attachment bracket for attaching to a moving carrier arm of a carrier device. The attachment cutting system comprises at least one motor and two cutting heads which are rotationally driven by said motor, are attached at both sides of the longitudinal axis of the attachment bracket, and carry numerous cutting teeth. Furthermore, a rotating cutter chain having numerous cutting teeth is provided, the direction of travel of which runs parallel to the longitudinal axis of the attachment bracket and which extends between the two cutting heads, wherein the front reversing line of the cutter chain lies substantially in a plane tangent to the outside cutting surfaces of the two cutting heads, and wherein the motor driving the cutting heads, and wherein the motor driving the cutting heads also drives the cutter chain. | 10-13-2011 |

| 20100198317 | COCHLEA STIMULATOR - The invention provides a cochlea stimulator for implantation comprising optical fibres of which are coupled to an irradiation source that is controlled by a modulator to generate irradiation specific for a pre-determined range of sound-frequencies. The cochlea stimulator effects a frequency-specific activation of the organ of Corti needed for speech perception especially in noisy environment and more complex sounds. For imparting excitation signals which are generated by modulated pulsed laser irradiation conducted within an optical fibre in order to elicit nervous signals in residual functional organ of Corti sections, the auditory prosthesis preferably contains optical fibres which are dimensioned to terminate in end sections within the cochlea at different sites or sections of the organ of Corti. e.g. having different lengths for locating their end sections at different internal parts of the cochlea. | 08-05-2010 |
