Resistance Compensator to Reduce Uncertainty in Determination of Movement of a Structural Member

NIST Inventors

Matthew Hoehler and Christopher Smith

The invention is a method of estimating thermal expansion in a "wire" (a long, thin, flexible element that may be metallic or nonmetallic) by measuring changes in its electrical resistance. In some materials, the electrical resistance and thermal expansion are both almost linearly dependent on the

Differential compensator to reduce uncertainty in determination of movement of a structural member

NIST Inventors

Matthew Hoehler and Christopher Smith

A new method has been developed for estimating the thermal expansion of a measurement cable (metallic wire or ceramic fiber thread) that is placed in a high temperature environment with an unknown temperature profile and connected to a moving target. This method is to deploy a second measurement

Icemaker, Process for Controlling Same and Making Ice

NIST Inventors

David A. Yashar

A system to make ice includes a refrigeration unit and an icemaker disposed in the refrigeration unit. The refrigeration unit is configured to be subjected to a refrigeration cycle; the icemaker is configured to be subjected to a freeze cycle; and the system is configured such that the freeze cycle

Optical Temperature Sensor

NIST Inventors

Zeeshan Ahmed , Steve Semancik , Jacob Taylor and Gregory F. Strouse

A thermometer includes a substrate; an optical resonator disposed on the substrate and including an optical resonance, the optical resonator being configured to receive a resonant frequency corresponding to the optical resonance; and a waveguide disposed on the substrate proximate to the optical
