  • Publication number: 20170367418
    Abstract: A mold for casting a micro-scale structure includes an upper surface including a first cavity having a first depth. A negative pattern for an array of micro-scale structures is defined in a surface of the first cavity. The mold includes at least one second cavity having a second depth defined in the cavity outside of the negative pattern for the array of micro-scale structures. The at least one second cavity defines a negative pattern for a standoff of the micro-scale structure. A fabric retaining frame is disposed in the first cavity.

  • Publication number: 20170102263
    Abstract: An environmental physical sensor is provided that includes a power input terminal, a sensor output terminal, and a resonant switch. The resonant switch includes a mechanical element that is responsive to an environmental stimulus and is coupled to an electrical switch. The electrical switch is operable between an open position and a closed position and electrically connects the power input terminal to the sensor output terminal when in the closed position. The mechanical element is configured to intermittently actuate the electrical switch into the closed position responsive to the environmental stimulus.

  • Publication number: 20170097394
    Abstract: Aspects and embodiments are generally directed to magnetic field detector systems and methods. In one example, a magnetic field detector system includes a proof-mass including a magnetic dipole source, a plurality of supports, each individual support of the plurality supports being coupled to the proof-mass, a plurality of sensors, each individual sensor of the plurality of sensors positioned to measure a resonant frequency of a corresponding support of the plurality of supports, and a controller coupled to each individual sensor of the plurality of sensors, the controller configured to measure a characteristic of a magnetic field imparted on the proof-mass based on at least a first resonant frequency of the measured resonant frequencies.

  • Patent number: 9482553
    Abstract: Methods and apparatus for calibrating a gyroscope without rotating the instrument. In one example, a calibration method includes operating the gyroscope in a self-oscillation loop to generate x-axis and y-axis drive signals, adding forcing signals to the x-axis and y-axis drive signals to produce pick-off x-axis and y-axis signals, measuring the pick-off x-axis and y-axis signals to produce measurement data, determining a relative phase between the pick-off x-axis and y-axis signals, based on the measurement data and the relative phase, estimating parameters of the gyroscope, based on the measurement data and the estimated parameters, calculating estimated position signals to calibrate the gyroscope.

  • Patent number: 9150405
    Abstract: In one embodiment, a rotary device includes a multiwall nanotube that extends substantially perpendicularly from a substrate. A rotor may be coupled to an outer wall of the multiwall nanotube, be spaced apart from the substrate, and be free to rotate around an elongate axis of the multiwall nanotube.
