20130214780 | QUANTUM MECHANICAL MEASUREMENT DEVICE - A quantum mechanical measurement device is provided. A spin ensemble is provided. A first light source provides a first light at a first wavelength, wherein the first light source is positioned to provide light into the spin ensemble. A detector is positioned to detect light from the spin ensemble. A modulator modulates absorption of the first light from the first light source by the spin ensemble at a frequency greater than a Larmor frequency of the spin ensemble. | 08-22-2013 |
20130208571 | SOLID MARINE SEISMIC CABLE WITH AN ARRAY OF HYDROPHONES - In a first embodiment of the present invention, a hydrophone is provided comprising: a rigid tubular substrate; an annular cavity formed around the rigid tubular substrate by affixing a tubular diaphragm around the rigid tubular substrate; a flexible piezoelectric element wrapped around and bonded to the flexible tubular diaphragm; and a molded portion covering the piezoelectric element. | 08-15-2013 |
20080290867 | ALTERED SWEEP BELL-BLOOM MAGNETOMETER - A magnetometer is constructed wherein the sweeping is performed at one half the Larmor frequency and has as its center the absorption line. This allows the emitter to tune onto the absorption line twice per cycle as it passes through the line. This causes the increase in absorption as would the normal sweep of a Bell-Bloom magnetometer but avoids the drawbacks, such as drift and heading error. | 11-27-2008 |
