20100134104 | NUCLEAR MAGNETIC RESONANCE MEASUREMENT TECHNIQUES IN NON-UNIFORM FIELDS - Methods and pulse sequences for facilitating nuclear magnetic resonance (NMR) measurements in grossly inhomogeneous fields. Methods and pulse sequences according to the invention may be used to accurately measure variables such as transverse relaxation time, longitudinal relaxation time, and diffusion, without the need for data at long recovery time, thereby allowing for faster measurements. In addition, methods and pulse sequences according to embodiment of the invention may allow simultaneous encoding of information in both the amplitude and the shape of echoes, so as to allow a single-shot measurement of multiple variables, e.g., both transverse relaxation time (from the decay of echo amplitudes) and longitudinal relaxation time (from the echo shape). CPMG detection may be used to overcome the often limited signal-to-noise ratio in grossly inhomogeneous fields. | 06-03-2010 |

20130124121 | BATTERY PACK MANAGEMENT - A battery pack management system provides information such as remaining capacity and/or run time to empty for a battery. A time taken for a battery voltage to drop a threshold amount is measured and used to determine a remaining capacity of the battery. The time may be associated with a temperature and current of the battery. The remaining capacity of a battery is calculated by monitoring a discharge of the battery. For example, current drawn from the battery is monitored over a period of time and an initial amount by which the battery has been discharged is calculated. Compensation of this initial amount is carried out in order to take into account factors such as temperature, self-discharge rate and age of the battery. | 05-16-2013 |
