Abstract: Systems and methods for adjusting insurance premiums are provided. Embodiments provide systems and methods for providing a time-based adjustment to insurance premiums, as well as premium adjustment, and risk management. Some embodiments use collected data, such as telematics to take in data and determine, on a periodic basis, when a vehicle is actually moving and when it is not. In some embodiments, an insurance policy can be adjusted in real-time based on driving behaviors or restrictions.

Abstract: Disclosed are devices, materials, systems, and methods, including a device that includes one or more structural components, at least one of the one or more structural components comprising substantially HfO2—TiO2 material. Also disclosed is a hemispherical resonator that includes a hemisphere including one or more structural components with at least one of the one or more structural components comprising substantially HfO2—TiO2 material, a forcer electrode configured to apply an electrical force on the hemisphere to cause the hemisphere to oscillate, and one or more sensor electrodes disposed in proximity to the hemisphere and configured to sense an orientation of a vibration pattern of the hemispherical resonator gyroscope.

Abstract: A torsional gyroscope is provided that includes: a pickup tine and a drive tine of piezoelectric material, pickup electrodes disposed along the pickup tine, drive electrodes disposed along the drive tine, and a drive mass. The drive tine has a first end attached to the pickup tine and is transverse to the drive tine. The drive mass is attached to a second end of the drive tine opposite the first end of the drive tine. An electric field applied to the drive electrodes induces a rotational oscillation of the drive tine causing the drive tine to rotate about the first axis, inducing the drive mass to rotate about the first axis. Angular rotation of the drive mass along a third axis induces a torque in the pickup tine that induces an electric field in the pickup tine that induces an electrical charge to build up in the pickup electrodes.

Abstract: A micro-scale hemispherical resonator gyroscope includes a hemispherical resonator with a plurality of masses positioned around the periphery of the hemispherical resonator. At least some of the masses may be made of a heavy metal, such as tungsten, gold, platinum, or lead, and may be positioned at points of maximum deflection or velocity of the resonator. The hemispherical resonator may have a 2 mm diameter and a ring down time of at least 500 seconds.

Abstract: A sensor is fabricated with micron feature sizes capable of simultaneously measuring absolute angles of rotation and angular rotational rates. The measurements are made directly from the position and velocity of the device without the need for electronic integration or differentiation. The device measures angle directly, avoiding the integration of electronic errors and allowing for higher performance in attitude measurement. These performance improvements and flexibility in usage allow for long term attitude sensing applications such as implantable prosthetics, micro-vehicle navigation, structural health monitoring, and long range smart munitions. Through the fabrication of the device using lithographic methods, the device can be made small and in large qualities, resulting in low costs and low power consumption.
