2. Something, such as a message, that is transmitted.
3. An automotive assembly of gears and associated parts by which power is transmitted from the engine to a driving axle. Also called gearbox.
4. The sending of a signal, picture, or other information from a transmitter.

[Latin trānsmissiō, trānsmissiōn-, a sending across, from trānsmissus, past participle of trānsmittere, to transmit. See transmit.]

An LCD screen that uses a backlight. Transmissive LCDs are widely used in portable computers and provide excellent viewing indoors. They must be used outdoors in the shade because direct sunlight overwhelms the backlight, making viewing difficult, if not impossible.

Reflective LCD

A reflective LCD uses the ambient light in the vicinity. The light passes through the LCD layer to a mirror, which reflects it back to the viewer. Reflective LCDs are the least costly, but require bright light. Viewing is difficult in dark rooms or outside at night. Reflective LCDs can also be built with frontlights, which significantly improve the viewing in dimly lit environments.

Transflective LCD

A transflective LCD uses both transmissive and reflective methods. It uses a backlight as does transmissive, but also adds a reflective mirror that lets light pass through from the back.

Transflective LCDs are a compromise that allows users to obtain better viewing under both lighting conditions. However, because the mirror is built to let through backlight as well as reflect frontlight, it cannot do both equally as well as mirrors dedicated to one purpose. As a result, transflective LCDs are typically not quite as bright indoors as transmissive units and not as bright outdoors as reflective ones.

The transfer or conveyance of a thing or condition, such as an infectious or genetic disease or hereditary trait, from one person to another.

A four-speed manual transmission. Power from the rotating input shaft turns the countershaft (or … (credit: © Merriam-Webster Inc.)

System in an engine that transmits power generated by the engine to the point where it is to be used. Most mechanical transmissions function as rotary speed changers; the ratio of the output speed to the input speed may be either constant (as in a gearbox) or variable. On variable-speed transmissions, the speeds may be variable in individual steps (as on an automobile or some machine-tool drives) or continuously variable within a range. Step-variable transmissions, with some slip, usually use either gears or chains and provide fixed speed ratios with no slip; stepless transmissions use belts, chains, or rolling-contact bodies.

1. transfer, as of an infection from one patient to another.
2. of nervous impulses. See neuromuscular transmission.
3. heredity.

• airborne t. — spread of infection by droplet nuclei or dust through the air. Without the intervention of winds or drafts the distance over which airborne infection takes place is short, say 10 to 20 feet.
• arthropod t. — by insect, either mechanically via a contaminated proboscis or feet, or biologically when there is growth or replication of the organism in the arthropod. See also trans-stadial.
• biological t. — involving a biological process, e.g. passing a stage of development of the infecting agent in an intermediate host. Opposite to mechanical transmission.
• colostral t. — a form of vertical transmission via successive generations.
• contact t. — the disease agent is transferred directly by biting, sucking, chewing or indirectly by inhalation of droplets, drinking of contaminated water, traveling in contaminated vehicles.
• cyclopropagative t. — the agent undergoes both development and multiplication in the transmitting vehicle.
• developmental t. — the agent undergoes some development in the transmission vehicle.
• fecal-oral t. — the infectious agent is shed by the infected host in feces and acquired by the susceptible host through ingestion of contamined material.
• horizontal t. — lateral spread to others in the same group and at the same time; spread to contemporaries.
• mechanical t. — the transmitter is not infected in that tissues are not invaded and the agent does not multiply.
• propagative t. — the agent multiplies in the transmission vehicle.
• vector t. — see vector.
• vertical t. — from one generation to the next, perhaps transovarially or by intrauterine infection of the fetus. Some retroviruses are transmitted in the germ line, i.e. their genetic material is integrated into the DNA of either the ovum or sperm.
