摘要： Embodiments of the invention include an accelerometer system. The system includes an accelerometer sensor comprising first and second electrode configurations and an inertial mass between the first and second electrode configurations. In one example, the accelerometer sensor being fabricated as symmetrically arranged about each of three orthogonal mid-planes. The system also includes an accelerometer controller configured to apply control signals to each of the first and second electrode configurations to provide respective forces to maintain the inertial mass at a null position between the first and second electrode configurations. The accelerometer controller can measure a first pickoff signal and a second pickoff signal associated with the respective first and second electrode configurations. The first and second pickoff signals can be indicative of a displacement of the inertial mass relative to the null position. The accelerometer controller can calculate an acceleration based on the first and second pickoff signals.

摘要： A cell in one example comprises an alkali metal and a coating of parylene on an interior surface of the cell. In one implementation, the alkali metal may be an optically pumped gaseous phase of an alkali metal. The parylene coating minimizes interaction of the excited state of the alkali metal, increases lifetime of the excited state, and minimizes interaction of nuclear spin states with the cell walls.

摘要： A rotation sensor is formed of three semiconductor wafers. A first wafer comprises a frame that surrounds a paddle. The rotation-sensitive paddle is surrounded on either of the opposed sides of the first wafer by rings of driven elements formed of radially-directed plateaus in the semiconductor material. Second and third wafers sandwich the first wafer. Each of the second and third wafers includes a first surface in which are formed concentric rings of driver and pickoff electrodes. In a preferred embodiment, the rings of pickoff electrodes are split into two semicircular arcs.

摘要： An integrated optics chip with improved performance when exposed to changing temperature is disclosed. The optic chip or integrated optics chip or MIOC has a top surface, a +Z face and -Z face. The integrated optics chip is formed from a crystal substrate having a high electro-optic coefficient such as Lithium Niobate. For the purpose of orienting the components to the optic chip to be described, the +Z crystal axis extends outward from the +Z face, the Z axis being the axis across which a pyroelectric effect is exhibited. The top surface is orthogonal to the Z axis. An input waveguide on the top surface receives an optical signal from an input port, passes the signal via a waveguide network, to an output waveguide coupling the waveguide network to an output port. A portion of the +Z and -Z faces are coated at least partially with a conductive coating. A conductive path couples the +Z and -Z faces to prevent a charge differential from developing between the +Z and -Z faces due to a change in temperature of the optic chip and the pyroelectric effect.

摘要： An input optical fiber (22), an output optical fiber (24, 26) and a waveguide (14) in an integrated optic chip (IOC) (12) intermediate the fibers are coupled together using service and alignment robots (42; 48, 50, 52). The service robot (42) establishes the three dimensional position of the waveguide. The alignment robots (48, 50, 52) three dimensionally and angularly align the input and output fibers respectively to the input and output legs (16; 18, 20) of the waveguide.

Included are specifics for an optical fiber clamp (110) capable of maintaining the orientation of a fiber while it is moved to another location, a vacuum holder (210) for holding and rotating an optical fiber for polarization purposes, goniometer mapping and positioning of an optical fiber with respect to the pivotal axis of the goniometer (324), initial light launching of an optical fiber to a waveguide using the fiber (422) in its cladding mode, planar and angular position alignment of optical fibers to optical waveguides, an alignment procedure for establishing a gap between waveguides, and attaching optical waveguides together.

摘要： An integrated accelerometer includes features for minimizing the effects of foreseeable operational stresses. The accelerometer is of a type that includes a planar support base having an internal aperture for accommodating a hinged strut and limit stops for minimizing the travel of the shadow paddle portion of the strut. The limit stops are fabricated of material of suitable spring constant to provide an appropriate degree of "give" without degrading instrument performance or accuracy. Two-piece arrangements sandwich the hinges, thereby limiting flexure to an acceptable range. The predictable mechanical stresses resulting, for example, from thermal coefficient mismatches between the materials of the torquer coil and the strut are minimized by the use of a spacer intermediate the base and the coil. The spacer, fabricated of material whose thermal coefficient closely matches that of the pendulous mass is generally circular, and includes diametrically-opposed prongs on the upper and lower edges thereof, such arrangements of prongs being staggered by ninety degrees.
