Goniometer A goniometer is an instrument that either measures an angle or allows an object to be rotated to a precise angular position. The term goniometry is derived from two Greek words, gōnia, meaning angle, and metron, meaning measure.rior to the invention of the theodolite, the goniometer was used in surveying. The application of triangulation to geodesy was described in the second (1533) edition of Cosmograficus liber by Petri Appiani as a 16-page appendix by Frisius entitled Libellus de locorum describendorum ratione.

Human Chorionic Gonadotropin Pregnancy Test Last Update On: 2015-03-23. Human chorionic gonadotropin (hCG) is a glycoprotein secreted by the placenta during pregnancy that consists of an alpha and beta subunit. The alpha subunit is structurally similar to the alpha subunits of FSH, LH and TSH.The beta subunit is distinct for hCG.urrent pregnancy tests is available that can test either serum or urine. Once a specimen is applied to the device, results are available in 3 minutes for urine and 5 minutes for serum. Sensitivity is 10 IU/mL for serum and 20 mIU/mL for urine. hCG concentrations reach 10 to 25 mIU/mL by 7 to10 days after conception.

Gonioscopy How It Is Done. Gonioscopy is usually done by a doctor who treats eye problems (ophthalmologist). Eyedrops are used to numb your eye so that you will not feel the lens touching your eye during this painless examination.

What is Range of Motion? Range of motion is measured by your physical therapist using a device called a goniometer. A goniometer is a metal or plastic handheld device with two arms. Numbers representing angular distance are on the device, much like a protractor.

Accelerometer An accelerometer is a device that measures the vibration, or acceleration of motion of a structure. The force caused by vibration or a change in motion (acceleration) causes the mass to squeeze the piezoelectric material which produces an electrical charge that is proportional to the force exerted upon it.n accelerometer is a device that measures the vibration, or acceleration of motion of a structure.

Dynamometer A dynamometer or dyno for short, is a device for measuring force, torque, or power. For example, the power produced by an engine, motor or other rotating prime mover can be calculated by simultaneously measuring torque and rotational speed (RPM). A dynamometer can also be used to determine the torque and power required to operate a driven machine such as a pump.

What is Spirometry? Spirometry (measuring the lung capacity) is the most important test to diagnose and monitor COPD. COPD causes narrowing of the bronchial tubes (or airways), resulting in shortness of breath. The greater the narrowing, the more difficult breathing becomes. Spirometry is a test which measures exactly how much the bronchial tubes have narrowed. The spirometer measures the speed your lungs can be filled and emptied of air, giving an indication of how well your lungs are performing.

What is a Pupillometer? 10 hilariously insightful foreign words. A pupillometer is a device that measures the reactivity of the eyes' pupils. The pupillometer can be a large machine, connected to a wall, with a chair that allows one to sit and go through about 10 minutes of testing to evaluate the pupil’s reactivity to light.

Goniometry.ppt uche 1 Traditional goniometer. The traditional goniometer, which can be used for flexion and extension; abduction and adduction; and rotation in the shoulder, elbow, wrist, hip, knee, and ankle, consists of three parts:  A body. The body of the goniometer is designed like a protractor and may form a full or half circle.

- How to Make a Clinometer. A clinometer, also called a declinometer or an inclinometer, is an instrument that measures vertical slope, usually the angle between the ground or the observer and a tall object. A simple, or fixed angle, clinometer requires plenty of room to walk back and forth when measuring object.

Gonioscopy Guide. Gonioscopy is an eye examination to look at the front part of your eye (anterior chamber) between the cornea and the iris. Gonioscopy is a painless examination to see whether the area where fluid drains out of your eye (called the drainage angle) is open or closed.It is often done during a regular eye examination, depending on your age and whether you are at high risk for glaucoma.onioscopy is done to: 1  Look at the front of the eye to check for glaucoma. 2  See if the drainage angle of the eye is closed or nearly closed. 3  This helps your doctor see which type of glaucoma you have. 4  Gonioscopy can also find scarring or other damage to the drainage angle. 5  Treat glaucoma.

accelerometer An accelerometer is a device that measures changes in gravitational acceleration in a device it may be installed in. Accelerometers are used to measure acceleration, tilt and vibration in numerous devices. At rest, an accelerometer measures 1g: the earth’s gravitational pull, which registers 9.81 meters per second or 32.185 feet per second. Accelerometers that use the piezoelectric effect measure a small voltage change.

Accelerometers: What They Are & How They Work An accelerometer is an electromechanical device used to measure acceleration forces. Such forces may be static, like the continuous force of gravity or, as is the case with many mobile devices, dynamic to sense movement or vibrations. Acceleration is the measurement of the change in velocity, or speed divided by time.
