摘要： A method and system of inertia friction welding of work parts welded with a specified angular orientation with respect to each other. The method and apparatus comprises loading a sample work part into a rotating chuck attached to a spindle and loading another sample work part into a non-rotating chuck and then applying torque to the spindle to accelerate the spindle to achieve a predetermined first rotational speed. Next, the sample work parts are inertia friction welded together to form a sample weld. Then, the system measures and stores data related to the deceleration of the spindle during the sample inertia friction weld. The welded sample work parts are removed from the rotating and the non-rotating chucks. The system then calculates a sample deceleration profile of the spindle from the data acquired during the formation of the sample weld. Next, a production work part is loaded into the rotating chuck and another production work part is loaded into the non-rotating chuck. The system applies torque to the spindle to accelerate the spindle to the predetermined first rotational speed which is maintained a rotary position of the spindle matches a calculated value. The system then inertia friction welds together the production work parts to form a production weld. During the formation of the production weld, the system controls torque applied to the spindle during the inertia friction welding of the production work parts so that the spindle deceleration during the formation of the production weld matches the sample deceleration profile of the spindle during the formation of the sample weld and so that the production weld ends in the specified angular orientation of the work parts with respect to each other.

摘要： A method and system of inertia friction welding that enables the production of inertia friction welds in which the final upset can be controlled to an operator specified target. The method utilizes any profile-based upset control technique, including but not limited to torque modulation and pressure (load) modulation. The method dynamically modifies the profile upset setpoints to systematically drive the upset formation to produce a weld with the targeted upset. The method and system also enables the production of inertia friction welds in which the final welded part length can be controlled to an operator specified target. The system and associated method comprises inertia friction welding a pair of sample parts to form a sample weld while acquiring data relating to the formation of the sample weld. The system and associated method also comprises inertia friction welding a pair of production parts to form a production weld using the profile data acquired during the friction welding of the pair of sample parts to achieve the predetermined upset formation.

摘要： A method and system of direct drive friction welding to reduce upset variation or reduce welded part length variation and a method and system of inertia friction welding to reduce upset variation. The system comprises a spindle which is configured to engage a part and a drive which is operatively connected to the spindle to rotate the spindle, and associated microprocessor based devices to store data and command the drive. The method comprises a sample friction weld of parts, and storing data in connection therewith, in order to generate a profile of upset versus speed. The method then, through the modulation of spindle drive torque, uses this profile for additional production friction welds having upset versus speed characteristics consistent with the profile of the sample weld during a deceleration phase of the friction weld.

摘要： A method and system for blending biogas with conventional fuel in which the fuel blend is automatically adjusted for lower biogas flows and methane concentrations by introducing higher concentrations of conventional fuels. The system is able to automatically adjust the fuel blend, thereby eliminating the requirement for manual intervention, and producing a variable blended biogas that can be utilized within existing natural-gas fired combustion units such as boilers, furnaces, heaters, etc., as well as enabling automatic adjustment and operation, maximum usage of biogas, and integration with combustion unit controls. Using all available biogas to provide energy also minimizes the need for flaring unused biogas.

摘要： A method and circuit to perform noise shaped splitting of a digital input signal may include using multiple layers to process the input signal. In the first layer, the most significant bits of the input signal may be distributed to a plurality of branches. Dynamic element matching may be performed using the least significant bits of the input signal. Based on the results of the dynamic element matching, values may be added to the plurality of branches. If there is insufficient data activity, dynamics enhancement may be performed to increase the data activity. The output signals of each of the plurality of branches in the first layer may be provided to a second layer, in which these steps can be repeated on each of the output signals. The outputs of the second layer may be provided to a plurality of three level unit elements.

摘要： A microphone system has an output and at least a first transducer with a first dynamic range, a second transducer with a second dynamic range different than the first dynamic range, and coupling system to selectively couple the output of one of the first transducer or the second transducer to the system output, depending on the magnitude of the input sound signal, to produce a system with a dynamic range greater than the dynamic range of either individual transducer. A method of operating a microphone system includes detecting whether a transducer output crosses a threshold, and if so then selectively coupling another transducer's output to the system output. Some embodiments combine the outputs of more than one transducer in a weighted sum during transition from one transducer output to another, as a function of time or as a function of the amplitude of the incident audio signal.
