Method to estimate battery health for mobile devices based on relaxing voltages
Mobile devices are only as useful as their battery lasts. Unfortunately, the operation and life of a mobile device's battery degrade over time and usage.

To remedy this lack of support, a low-cost user-level SoH estimation service is developed for mobile devices based only on their battery voltage, which is already available on all commodity mobile devices. The design of the estimation service is inspired by an empirical observation that the relaxing voltages of a device battery fingerprint its SoH, and is steered by extensive measurements with 13 batteries used for various devices, such as Nexus 6P, Nexus 5X, Xperia Z5, Galaxy S3, iPhone 6 Plus, etc. |

Dart with changeable exterior profile
A dart for effecting wellbore operations has an inactivated position and an activated position wherein the exterior profile of the dart is changed when the dart is activated. The change in profile may be achieved by moving (for example, rotating) a portion of the dart relative to the remaining portion.

Bistable polynucleotide devices for the sensing and quantification of molecular events
Bistable devices are constructed using a polynucleotide platform for the sensing of molecular events such as binding or conformational changes of target molecules. Uses include measurement of target concentration, measuring the effect of environmental condition (such as heat, light, or pH) on the target, or screening a library for molecules that bind the target or modulate its biological function. Devices comprise three regions: a top lid, bottom lid, and flexible linker or hinge between them. A device has an open configuration in which the top and bottom lid are separated, and a closed configuration they are bound close together. Binding domains or variations of the target molecule are fixed to a device so that when the molecular event occurs, the device switches from open to closed, or vice versa, which generates a signal. Devices carry DNA tags to enable separation of open and closed devices, as well as barcoding for multiplexed detection. |
