20120081094 | REFERENCE VOLTAGE BASED EQUIVALENT SERIES RESISTANCE (ESR) EMULATION FOR CONSTANT ON-TIME (COT) CONTROL OF BUCK REGULATORS - The present invention uses a reference voltage that varies within a Pulse Width Modulation (PWM) cycle to generate the PWM signal. This allows for stability in the feedback of Constant On-Time (COT) control for buck controllers when low Equivalent Series Resistance (ESR) capacitors are used as the output capacitor. The reference voltage is adjusted using features of a PWM cycle in a voltage mode without using external inductor current information. | 04-05-2012 |

20160047458 | Method of Installing a Motor on a Gear Box - A method of mounting a motor to a gearbox includes positioning a coupling along an input shaft of the gearbox from a starting position to a first alignment position. In the starting position, the coupling drivingly engages a greater portion of the gearbox input shaft than in the first alignment position. In the first alignment position, the coupling operatively contacts the motor output shaft. Another step includes rotating the coupling so that the coupling aligns with the motor output shaft. Another step includes axially positioning the coupling at a second alignment position such that the coupling drivingly engages both the motor output and the gearbox input shafts. Another step includes positioning the motor to allow mounting of the motor on the gearbox with the coupling at a third alignment position drivingly engaging a greater portion of the motor output and the gearbox input shafts than in the second alignment position. | 02-18-2016 |
20160069446 | Lubrication System for a Gear Box and Associated Methods - A lubrication system for a gear box has a backing member. The backing member is configured to allow mounting of a plurality of lubrication components on the backing member. One of the lubrication components comprises a pump configured to pressurize lubricating oil for the lubrication system. The pump has a suction and discharge. The pump suction is removably connectable to the gear box and the pump discharge is removably connectable to piping that is configured to communicate with the gear box. The backing member has a lifting mount arranged along its length and width that corresponds to a center of gravity of the backing member with the lubrication components mounted thereto. The lubrication components are modular and may be replaced and installed as necessary on the backing member. Multiple like lubrication systems may be provided, and removed and installed on the gear box as needed for maintenance. | 03-10-2016 |

20120176666 | LASER APPARATUS AND METHOD TO GENERATE UV LASER LIGHT - This invention relates generally to laser systems that produce UV light and their methods of use. The phase matching of the conversion process has a broad temperature bandwidth so that precise temperature stabilization is not necessary to obtain a stable efficiency and a non-deformed laser beam with fast power modulation at high energies. | 07-12-2012 |

20090057971 | Universal holding fixture - A universal holding fixture assembly includes a plurality of linear actuators supported by the fixture and adapted to engage and support a workpiece relative to the fixture. A linear displacement member is supported by a housing and adapted to move between retracted and extended positions. An end effector assembly is operatively supported by the linear actuator and adapted to engage the workpiece when the linear displacement member is in its extended position. A sensor is operatively supported by the end effector assembly and is responsive to contact with the workpiece to establish a datum of the position of the linear actuator relative to the workpiece. | 03-05-2009 |
