Hand grip strength assessment. In the medical terminology, hand-held dynamometers are used for routine screening of grip and hand strength, and the initial and ongoing evaluation of patients with hand trauma or dysfunction. They are also used to measure grip strength in patients where compromise of the cervical nerve roots or peripheral nerves ...
The first electric-powered torque amplifier was invented in 1925 by Henry W. Nieman of the Bethlehem Steel Company of Bethlehem, Pennsylvania. [1] It was intended to allow manual control of heavy equipment; e.g., industrial cranes, artillery, etc. Vannevar Bush used Nieman's torque amplifier as part of his differential analyzer project at M.I.T in the early 1930s.

A host of functions required for ECU software calibration, such as interface-dependent calibration methods, calibration data management, measurement data visualization and analysis, ECU programming, vehicle bus monitoring, as well as remote control through standard interfaces, are part of the product's functional complement.
It is a measure of the efficiency of the gasoline engine by measuring the percentage of oxygen in the exhaust. When gasoline engines operate with a stoichiometric mixture of 14.7: 1 the value of lambda (λ) is "1". Mixing ratio = weight of fuel / weight of air - Expressed as mass ratio: 14.7 kg of air per 1 kg. of fuel.
Hand-held meters use batteries, while bench meters usually use mains power; either arrangement allows the meter to test devices. Testing often requires that the component under test be isolated from the circuit in which they are mounted, as otherwise stray or leakage current paths may distort measurements.
