    摘要： The disclosure is directed to matching a time delay and a bandwidth of a plurality of sensors. An aspect receives first sensor data having a first timestamp from a first sensor having a first bandwidth, receives second sensor data having a second timestamp from a second sensor having a second bandwidth, and synchronizes the first sensor data and the second sensor data by performing one or more of compensating for a first time delay of the first sensor data, compensating for a second time delay of the second sensor data, compensating for a relative time delay between the first sensor data and the second sensor data, or matching the first bandwidth and the second bandwidth to a common bandwidth.

    摘要： Techniques are described herein that perform pressure sensing using pressure sensor(s) that include deformable pressure vessel(s). A pressure vessel is an object that has a cross section that defines a void. A deformable pressure vessel is a pressure vessel that has at least one curved portion that is configured to structurally deform (e.g., bend, shear, elongate, etc.) based on a pressure difference between a cavity pressure in a cavity in which at least a portion of the pressure vessel is suspended and a vessel pressure in the pressure vessel.

    摘要： Systems and methods for an optically dithered atomic gyro-compass are provided. In one embodiment, an inertial sensor comprises: a vacuum chamber containing a cloud of laser cooled alkali atoms, wherein the atoms are free to fall under the influence of gravity;a first set of laser sources applying a first set of laser beams into the cloud along a first axis;a second set of laser sources applying a second set of laser beams into the cloud along a second axis;wherein the first set and second sets of laser beams apply coherent laser pulses that separate a wave function of the atoms along trajectories defining a plane sensitive to rotation about an axis orthogonal to the plane; and wherein the first and second set of laser sources apply dithering to the axis by modulating a relative magnitude of the first laser beams with respect to the second laser beams.
