| 20100238588 | FEED-FORWARD METHOD FOR REPEATABLE RUNOUT CANCELLATION - A magnetic hard disk drive includes a method for eliminating that portion of track following error by a read/write transducer that is caused by repeatable runout of the disk tracks. The repeatable runout is eliminated by application of an iterative algorithm that calculates feed-forward correction terms based on gain coefficients iteratively calculated from the amplitude and phase portions of a Bode plot characterizing the system. The corrective coefficients can be inserted into the hard disk drive at a summing junction that redefines the centerline of the track, or at a summing junction that causes the actuator to follow the repeatable runout and make non-repeatable runout corrections relative thereto. | 09-23-2010 |
| 20110320046 | Drive method for starting and operating a resonant scanning MEMS device at its resonant frequency - The resonance frequency of a forced torsionally oscillating mirror MEMS device can be controlled in the presence of perturbations by means of a closed loop feedback device and method of using it. The method is implemented through a simple algorithm, implemented in either software or hardware, that maintains the condition of resonance, or another selected frequency, by recursively determining that the center of the driving voltage pulse is positioned at a point on the measured positional waveform of the oscillating system. | 12-29-2011 |

| 20120085587 | Wind Power for Electric Cars - A modular wind turbine device mountable in a plurality of locations along the exterior of a vehicle. The device comprises a low profile air inlet, a rotatable turbine that utilizes incoming air flow for motive power, and an alternator device for transforming the rotation of the turbine into usable electric power. The air inlet is a raised air scoop that protrudes from the external surface of the vehicle, similar to forced air induction inlets or brake cooling inlets on current vehicles. The inlet is shrouded with a mesh screen to prevent discrete objects from entering or interfering with the turbine device. The turbine is an elongated cylinder with protruding fins that utilize the pressure of the incoming air flow to spin about its central axis. A side-mounted alternator provides a core that spins within a stator to produce an electric current. The electric current is fed to a power management system for controlling and powering a battery pack. The device is ideal for offsetting electric power usage in electric cars by utilizing the overflowing air pressure to induce mechanical motion and create an onboard power generation source. | 04-12-2012 |

| 20090132411 | Methods and systems for providing a constant maturity commodity index - Methods and systems provide a commodity index for investing. In one implementation, a method selects a commodity component for inclusion in the commodity index and calculates a target weight of the commodity component. The method further selects a time interval for maturity of the commodity component to be fixed at from a current date. Financial instruments may be purchased corresponding to the commodity component. | 05-21-2009 |
| 20090132434 | Methods and Systems for Determining Composition of a Commodity Index - Methods and systems provide a commodity index for investing. In one implementation, a method selects a commodity component for inclusion in the commodity index and calculates a target weight of the commodity component. The method further selects a time interval for maturity of the commodity component to be fixed at from a current date. Financial instruments may be purchased corresponding to the commodity component. | 05-21-2009 |

| 20090001972 | CALIBRATION CIRCUITS AND METHODS FOR PROXIMITY DETECTOR - A proximity detector employs a first peak detector circuit and a second peak detector circuit, both responsive to a magnetic field signal. The second peak detector circuit includes a positive peak detector circuit and a negative peak detector circuit, each of which have a predetermined excursion limit in an outward direction away from a center voltage of the magnetic field signal so as to be less affected by a large signature region in the magnetic field signal. The proximity detector also includes an output control circuit. The output control circuit is configured to provide an output signal, which, during a determined time period, changes state in response to the first peak detector circuit, and which, after the determined time period, changes state in response to the second peak detector circuit. | 01-01-2009 |
