1. Sclerosis (hardening and thickening of body tissue) occurring in patches in the brain or spinal cord or both, and characterized by tremors, failure of coordination, and various nervous and mental symptoms.
2. A chronic illness caused by lesions in the white matter of the central nervous system that degenerate the myelin sheath (insulating layer surrounding vertebrate peripheral neurons), marked by lack of muscle coordination, muscle weakness, speech problems, paresthesia, and visual impairments.

Paresthesia refers to the abnormal neurological sensations which include: numbness, tingling, burning, prickling, and hyperesthesia (increased sensitivity).

The cause of multiple sclerosis is unknown, but it is believed to be an autoimmune disorder, in which the body's immune system mistakenly attacks its own tissues.

Its symptoms vary, depending on which nerves lose their protective cover.

The connecting of two or more series of circuits in parallel.

A gravitationally bound group of two or more stars that orbit a common center of mass.

In radar countermeasures, a device that produces multiple false targets on enemy radar.

An effect in which the boundary of the troposphere and stratosphere appears as several overlapping discontinuities instead of as a single one.

1. A large movie theater complex that has several separate units with screens.
2. The simultaneous transmission of two or more signals along one communications channel.
3. A description of a communications system that can send several messages (signals) over one transmission path at the same time.

In cartography, it refers to a device that projects aerial photographs onto a surface in three dimensions; used to produce topographic maps.

An electronic device that allows a reader to have more than one antenna.

Each antenna scans the field in a preset order. This reduces the number of readers needed to cover a given area; such as, a dock door, and prevents the antennas from interfering with one another.

A device that supports multiple readers by checking each one in accordance with a scheduling scheme.

A number that is multiplied by another number (the multiplier).

1. A mathematical operation, symbolized by "x", that for integers is equivalent to adding a number to itself a particular number of times: "Three times (x) three equals nine (3 x 3= 9)."

3. A marked increase in number or amount: "There was a multiplication of claims made by people who lost their homes as a result of the hurricane."

2. The multiplying number or the number by which another number multiplicand is multiplied; for example, the number 5 is the multiplier in the numerical composition 5 x 6 = 30; in 8 × 32, the multiplier is 8.
3. A device, such as a phototube, used to enhance or increase an effect.
