Filed:

Apr 13, 2011

Appl. No.:

13/085900

International Classification:

G01P 15/00

US Classification:

702141

Abstract:

An accelerometer system can include a sensor element comprising first and second proofmasses, the first proofmass accelerating in a first direction and the second proofmass accelerating in a second direction opposite the first direction in response to an external acceleration. A force rebalance controller applies control signals to at least one control element to provide a first force to accelerate the first proofmass toward a first null position and to at least one control element to provide a second force to accelerate the second proofmass toward a second null position. The force rebalance controller can also generate opposite polarity first and second output signals associated with respective displacements of the first and second proofmasses relative to the respective first and second null positions. An acceleration component calculates the external acceleration based on the first and second output signals.

California Institute of Technology - Pasadena CA

International Classification:

A61K 3722
A61K 4700

US Classification:

424450

Abstract:

Closed, unilamellar vesicles are spontaneously formed by adding a cholesteryl compound substituted with a hydroxyl terminated polyethylene oxide containing 1 to 4 ethylene oxide groups to a polar liquid. Multilamellar vesicles are formed by sonicating a cholesteryl compound containing polyethylene oxide or polyamine side-chains. The vesicles can be utilized to dispense polar, non-polar or ampholphilic compounds.

International Classification:

H02J 7/00
H02M 3/335

Abstract:

Various disclosed embodiments include illustrative controller modules, direct current (DC) fast charging devices, and methods. In an illustrative embodiment, a controller module for a DC-DC converter includes a controller and computer-readable media configured to store computer-executable instructions configured to cause the controller to receive an input voltage Vto the DC-DC converter, receive an output DC voltage Vfrom the DC-DC converter, generate control signals configured to control a charging output of the DC-DC converter responsive to the received input voltage Vand output voltage V, and output the generated control signals to the DC-DC converter.

International Classification:

B60L 53/10
H02J 7/00

Abstract:

Various disclosed embodiments include illustrative controller units, direct current fast charging (DCFC) units, and methods. In an illustrative embodiment, a controller unit includes a controller and a memory configured to store computer-executable instructions. The computer-executable instructions are configured to cause the controller to determine status of a power electronics module (PEM) of a direct current fast charging (DCFC) unit, and instruct the PEM to control power quality of a three-phase alternating current (AC) grid power signal in response to the determined status being available.

International Classification:

H01M 8/10

Abstract:

A membrane electrode assembly includes an anode catalyst layer, a cathode catalyst layer, and a polymeric blend proton exchange membrane interposed between the anode catalyst layer and the cathode catalyst layer. The polymeric blend proton exchange membrane includes a scaffold polymer and a polyacid polymer. The polyacid polymer being formed from a polyacid polymer precursor. Characteristically, the scaffold polymer and the polyacid polymer precursor have matching solubility parameters.
