Abstract:
An optical component is disclosed, as well as articles of manufacture, methods for forming, and methods of operating thereof. The optical component may include a plurality of patterned two-way shape memory alloy portions. Each patterned two-way shape memory alloy portion may include a reflective surface and a temperature adjustment element. Each patterned two-way shape memory alloy portion may be individually configured to flex to a first bend angle at a first temperature and a second bend angle at a second temperature.
Abstract:
Sensors for detecting at least one electrolyte in a conductive solution are described. The sensors may include a dielectric substrate and a resonator having a resonance characteristic and configured to generate a signal in response to an interrogation signal. The resonator may include a conductive layer in contact with the dielectric substrate, at least one layer of nanotubes provided on the conductive layer, and a dielectric layer at least partially encapsulating the nanotubes.
Abstract:
A tunable spectrometer is described. A tunable spectrometer may include an optical filter, having a first reflector stack and a second reflector stack separated by a half-wave spacer, a heater, a heat-sink and a detector array. At least one of the first reflector stack, the second reflector stack, and the half-wave spacer is made from a thermo-optic material. The heater and the heat sink are separately in contact with at least one of the first reflector stack, the second reflector stack, and the half-wave spacer. The detector array is configured to collect an output from the optical filter. In various embodiments, the heat and the heat sink may be separated by an optically transparent thermal isolator.
Abstract:
A smartpen configured for hands free audio recording is disclosed. One example smartpen may be configured so that a microphone contained in the smartpen is automatically oriented for unobstructed reception of ambient sound when the smartpen is placed on a supporting surface. Another example smartpen may have a weight distribution that causes the smartpen to roll to a desired orientation of the microphone when the smartpen is placed on a supporting surface with the microphone in a different orientation. Still another example smartpen may have one or more surface features disposed on a surface of the body of the smartpen, where the surface features are configured to position the microphone in a desired orientation when the smartpen is placed on a supporting surface.
