Scleral Contact Lenses for Other Eye Problems. In addition to keratoconus, scleral contact lenses can be used for eyes that have undergone a cornea transplant, and for people with severe dry eyes caused by conditions such as Sjogren's syndrome, graft-versus-host disease (GVHD) and Stevens-Johnson syndrome.
Aneroid sphygmomanometer with an adult cuff. A sphygmomanometer (pronounced /ËsfÉªÉ¡moÊmÉËnÉmÉ¨tÉr/. SFIG-moh-mÉ-NOM-i-tÉr) or blood pressure meter is a device used to. measure blood pressure, comprising an inflatable cuff to restrict blood. flow, and a mercury or mechanical manometer to measure the pressure. It is always used in conjunction with a means to determine at what. pressure blood flow is just starting, and at what pressure it is. unimpeded.
Magnetometers are devices that measure magnetic fields. A magnetometer is an instrument with a sensor that measures magnetic flux density B (in units of Tesla or As/ m2). Magnetometers refer to sensors used for sensing magnetic fields OR to systems which measure magnetic field using one or more sensors.Since magnetic flux density in air is directly proportional to magnetic field strength, a magnetometer is capable of detecting fluctuations in the Earth's field.n example is a fluxgate magnetometer that can measure the strength of any component of the Earthâs field by orienting the sensor in the direction of the desired component. â¢ Scalar magnetometers that measure only the magnitude of the vector passing through the sensor regardless of the direction.
