摘要： An adaptive seat is run in with an isolating object to beyond a landing location for the adaptive seat. The adaptive seat is released to expand and engage the surrounding tubular. Pressure from below acts on the object and propels the object against the adaptive seat. The object and the adaptive seat move in the tubular to a nearby landing location such as a groove or recess in a sub that is part of the string or another location such as a tubular joint where the adaptive seat finds support. An upper portion of the borehole is isolated for a time from formation pressure to allow running in an ESP from the surface. The object is removed by degradation or from being structurally undermined and the ESP is operated to produce the formation. One or more removable barriers are contemplated.

摘要： Described herein is a method including measuring a current in a wire, normalizing the measured current, and comparing the normalized measured current to a control curve. The control curve is a function of a series of normalized current magnitudes and reaction times for corresponding ones of that series of normalized current magnitudes. The method further includes limiting the current in the wire based upon the comparison. The reaction times for ones of the series of normalized current magnitudes are times at which current limitation would occur if the normalized current remained at an associated normalized current magnitude.

摘要： A plastic material substrate has a die mounting location for a semiconductor die. Metallic traces are formed on selected areas of the plastic material substrate, wherein the metallic traces provide electrically-conductive paths for coupling to the semiconductor die. The semiconductor die is attached onto the die mounting location. The semiconductor die attached onto the die mounting location is electrically bonded to selected ones of the metallic traces formed on the plastic material substrate. A package material is molded onto the semiconductor die attached onto the die mounting location.

摘要： Disclosed herein is a control system for a projection system, including a first subtractor receiving an input drive signal and a feedback signal and generating a first difference signal therefrom, the feedback signal being indicative of position of a quasi static micromirror of the projection system. A type-2 compensator receives the first difference signal and generates therefrom a first output signal. A derivative based controller receives the feedback signal and generates therefrom a second output signal. A second subtractor receives the first and second output signals and generates a second difference signal therefrom. The second difference signal serves to control a mirror driver of the projection system. A higher order resonance equalization circuit receives a pre-output signal from an analog front end of the projection system that is indicative of position of the quasi static micromirror, and generates the feedback signal therefrom.

摘要： A method of operating a MEMS device includes generating a MEMS drive signal, and generating and modifying the MEMS drive signal based upon a control signal to produce a modified drive signal. The method further includes generating the control signal by determining when a feedback signal from the MEMS device is at its peak value, comparing the peak value to a desired value when the feedback signal is as its peak, and generating the control signal depending upon whether the peak value is at least equal to a desired value. The modification of the MEMS drive signal based upon the control signal to produce the modified drive signal includes skipping generation of a next pulse of the modified drive signal when the control signal indicates the peak value is at least equal to the desired value.
