1. In naval mine warfare, a magnetic cable sweep in which the water forms part of the electric circuit.
2. A sweep fitted with cutters or other devices to increase its ability to cut mine moorings.

A sweep refers to the employment of technical means to uncover planted microphones or other surveillance devices and explosive mines in the water.

1. Determination of the nature of a disease through observation of changes in electrical irritability.
2. The diagnosis of a disease or a dysfunction of the central and peripheral nervous systems and voluntary muscles by any method utilizing electrical stimulation or recording electrical activity.
3. Diagnosis of a disease or injury based on electrodiagnostic tests or procedures with electric stimulation of various nerves and muscles.

This technique is helpful in almost all branches of medicine; especially, when investigating the functions of the heart, the nerves, and the muscles.

A reference to electrodiagnosis or involving or obtained by the recording of responses to electrical stimulation or of spontaneous electrical activity (as in electromyography) for purposes of diagnosing a pathological condition.

The use of electrical and electronic devices administered for diagnostic purposes.

This technique is helpful in almost all branches of medicine, but particularly when investigating the functions of the heart, nerves, and muscles.

1. A method of rapidly separating electrolytes from colloids by dialysis or by passing a current through a solution containing both elements.
2. A process in which an electric field transports ionized material through a membrane to separate it from other liquids or ions of opposite charge.
3. A system that uses electrical current applied to permeable membranes to remove minerals from water; for example, to desalinate salt water or brackish water.

A dialyzer (semipermeable membrane used for separation of smaller molecules in a solution from larger molecules in a liquid) that rapidly removes electrolytes from colloids by applying an electric field across the semipermeable membrane.

An appliance for cataract extraction (opacity of the lens of the eye which impairs vision) by means of a diathermy adhesion.

An instrument which introduces light into a body cavity to illuminate its internal contours and transilluminate its walls or to shine light through an organ of the body.

A system for carrying high-voltage electricity.

1. An acoustical device; such as, a loudspeaker or microphone, that derives electroacoustic energy from the action of a current or the motion of a conductor in a magnetic field.
2. A process that functions with the force of electricity in motion.
3. Relating to electrodynamics or the science that studies electrical forces (electrical current and magnetism) in interaction.

An instrument which depends for its operation on the reaction between the current in one or more movable coils and the current in one or more fixed coils.

1. The study of the relationships between electromagnetic and mechanical phenomena.
2. A branch of physics that studies how electric currents interact with magnetic and mechanical force including the the mutual influence of electric currents, the interaction of currents and magnets, and the influence of an electric current on itself.
3. The study of electrostatic charges in motion; such as, the flow of electrons in an electric current.
4. The science of energy transformations as related to electric currents and their magnetic fields.

1. A appliance used to measure electric power or for measuring the strength of an electric current by the magnetic force it induces in a coil.
2. An instrument that measures electric current by indicating the level of magnetic attraction or repulsion between a fixed and a movable coil, one of which carries the current to be measured.
3. A two-coil measuring instrument which measures the torque resulting from the reaction between the two series-connected current-carrying coils balanced by a spiral spring.
4. A tool for measuring electric current, activated by the torque resulting from the reaction of two current-carrying coils in a series.
5.An instrument for measuring the magnitude of electric currents.

An electronic device used to measure pressures exerted in biologic activity; such as, those exerted by the human foot in walking, running, jogging, or climbing stairs.

1. The induction of ejaculation by the application of a gradually increasing electrical current delivered through a probe inserted into the rectum.

It is used in animal husbandry and for the collection of sperm for insemination from men with spinal cord injuries and other medical conditions which prevent ejaculation.

2. An electrical stimulation applied to the rectum in order to produce an ejaculation of semen.

This is commonly used for spinal cord injury or testicular cancer patients who cannot ejaculate and are attempting artificial insemination.

It may also be used for those with abdominal injuries, multiple sclerosis, diabetic neuropathy, and anejaculation from other causes, both physical and psychogenic.
