    Abstract: Apparatus in accordance with embodiments of the present invention provide torque realization via electrical measurements traceable to the revised International Standard of Units (SI). Torque can be realized via a conversion of linear mechanism of a Kibble balance to a rotational mechanism. Embodiments of the present invention relates to an electronic torque realization apparatus including a rotor for holding permanent magnets and an encoder scale ring and for coupling to a torque device, a stator for characterizing physical aspects of a torque tool and for generating the torque on rotor in conjunction with the permanent magnets, a base plate for mounting a first end of rotor and stator, a cantilever for supporting a second end of rotor and for maintaining axial alignment, a bearing assembly for supporting the motion of rotor, and encoder for recording the angular position of rotor.

    Abstract: A lung fluid monitor monitors a fluid level in a lung and includes: a radiation source disposable on a first body surface and that produces nascent radiation, the nascent radiation: being received by the first body surface, communicated from the first body surface to a lung, attenuated proportionately to an amount of fluid in the lung, and communicated from the lung to a second body surface as attenuated radiation; a radiation detector disposable on the second body surface opposing the first body surface and in electromagnetic communication with the radiation source via the lung and that: receives the attenuated radiation from the lung and produces a detector signal from the attenuated radiation in response to receiving the attenuated radiation.

    IPC: G01P15/093

    CPC classification number: G01P15/093

    Abstract: An optomechanical accelerometer includes: a fiducial mass for a microscale Fabry-Perot optical cavity; a proof mass for the microscale Fabry-Perot optical cavity, such that the proof mass oscillates in a displacement motion toward and away from the fiducial mass in response to acceleration of the optomechanical accelerometer; a basal member; microscale beams that mechanically suspend the proof mass from the basal member; and the microscale Fabry-Perot optical cavity that has a cavity resonance at a cavity resonance wavelength provided by the cavity length, receives excitation radiation at an excitation wavelength that is reflected in the cavity as dynamic cavity light when the excitation wavelength is resonant with the cavity resonance wavelength, and transmits the dynamic cavity light as cavity output light when the dynamic cavity light is produced from the excitation radiation.
