accelerometer Definition

ac·cel·er·om·eter (ak sel′ər ämət ər, -ə räm-; -ək-)

noun

a mechanical or electromechanical instrument for measuring acceleration, as of an aircraft, or for detecting vibrations, as in machinery

Etymology: acceler(ate) + -o- + -meter

accelerometer Usage Examples

Converse of object

  • use: The movement of the structure was recorded using accelerometers.
  • attach: These signals are obtained from an accelerometer attached to the cardiac walls of patients who are recovering from by-pass surgery.
  • mount: Your speed is monitored using a trainer mounted accelerometer ( Foot Pod ) that wirelessly transmits your speed.
  • call: Children in the Sports Pro-Active program will have their activity levels monitored using a device called an accelerometer.
  • wear: The Trost bands are taken from large-scale research into young people's exercise ( whilst wearing accelerometers ).
  • fit: Knowing how stiffness influences the speed, field tests were conducted with seven accelerometers fitted on skis to identify the most important vibrations.

Converse of subject

  • detect: These changes are detected by an accelerometer and interpreted as a command.

Adjective modifier

  • 3d: The 3D accelerometer that changed the pitch has been replaced with a 1D one that is easier to control.
  • micromachined: This is certainly the case with experimental micromachined diamond accelerometers analogous to those made in silicon.
  • triaxial: Quiet stance was assessed using a triaxial accelerometer and balance performance monitor simultaneously.

Modifies a noun

  • device: The project involves a simulation of specks with accelerometer devices attached, scattered randomly over the surface of a spinning disk.
  • signal: Deflexion of the material is measured by a potentiometer or double integration of the accelerometer array signals.
  • datum: The physical characteristics of the car are reverse engineered from the accelerometer data collected through the pedestrian impactor testing in EuroNCAP.

Noun used with modifier

  • two-axis: The HMR3300 is a three-axis, tilt compensated compass that uses a two-axis accelerometer for enhanced performance up to a 60° tilt range.
  • axis: See also the HMC1055 which includes a HMC1051, HMC1052 and a two axis accelerometer for this application.
  • piezoelectric: It is a surface micromachined piezoelectric accelerometer employing a zinc oxide ( ZnO ) active piezoelectric film.
  • three-axis: To measure pitch and roll information, a two-axis tilt sensor, or a two or three-axis accelerometer is commonly used.

Preposition: for
