• Analogy is a similarity between two or more things.

• Analogy is an extension of the metaphorical parable thinking

founded on the existence of parallel cases.

• The analogy is typically used in the world of science, electrical

and fluid mechanics, the word analog etc ... etc ...?

Example:

The behavior of the electrical circuitry is the same as that of

the hydraulic circuitry in fact the electric vocabulary mimics the

hydraulic one

THE BIONIC ANALOGY-The bionic analogies use as reference elements of nature.

- Nature has perfected and selected mechanisms and procedures for millennia, if

these mechanisms were not effective and efficient species that should not have

lasted.VEGETABLES

- Plants resistant composite

materials that support high

tensions.

- Chemical factories without

moving parts.

- Adaptative and self learning

organisms

- Good ways and means of seed

dispersal.

- Gluing forms (Velcro)

ANIMALS

-Insects intriguing mechanisms,

- Mechanisms for drilling, insects,

birds

- Skins slide in one direction only

- How the mind works ?, neural

machines likely to learn

We have already taken the first step in the self-reproduction of artificial

elements, computer viruses are a good example.

PAVE PAWS is a United States Air Force Space Command radar system operated by three 21st Space

Wing squadrons for missile warning and space surveillance.

PAVE, an acronym which stands for "Precision Avionics Vectoring Equipment", is an Air Force program

name relating to electronic systems, while PAWS stands for "Phased Array Warning System". The

radar, developed by Raytheon, is used primarily to detect and track sea-launched (SLBM) and

intercontinental ballistic missiles (ICBMs). source Wikipedia

An aspect of this radar is phased array

antenna technology. This system differs from

a mechanical radar, which must be physically

aimed at an object in space to detect and/or

track it. The phased array antenna is in a fixed

position and can be part of the building wall.

Phased array antenna aiming, or beam

steering, is done rapidly by electronically

controlling the phase (or timing) of the

incoming and outgoing signals. Controlling the

phase through the many segments of the

antenna system allows the beam to be quickly

projected in different directions.

This greatly reduces the time necessary to change the beam direction from one point to another, allowing almost

simultaneous tracking of multiple targets while maintaining the surveillance responsibility. This ability is known as "track

while scan". The large fixed antenna array through its better beam focusing, improves system sensitivity and tracking

accuracy.

A phased array antenna, as with any other directional antenna, will receive signals from space only in the direction in

which the beam is aimed. The maximum practical deflection on either side of antenna center of the phased array beam

is 60 degrees. This limits the coverage from a single antenna face to 120 degrees. To provide surveillance across the

horizon, the building housing the entire system and supporting the antenna arrays is constructed in the shape of a

triangle. The two building faces supporting the arrays, each covering 120 degrees, will monitor 240 degrees of azimuth.

The array faces are also tilted back 20 degrees to allow for an elevations deflection from three to 85 degrees above

horizontal. The radar system is capable of detecting and monitoring a great number of targets that would be consistent

with a massive missile attack. The system must rapidly discriminate between vehicle types, calculating their launch and

impact points in addition to the scheduling, data processing and communications requirements.

Arthropod eyes are called compound eyes because they are made up of

repeating units, the ommatidia, each of which functions as a separate visual

receptor.

Each ommatidium consists of a lens (the front surface of which makes up a

single facet) a transparent crystalline cone light-sensitive visual cells

arranged in a radial pattern like the sections of an orange pigment cells which

separate the ommatidium from its neighbors.

The pigment cells ensure that only light entering the ommatidium parallel (or

almost so) to its long axis reaches the visual cells and triggers nerve impulses.

Thus each ommatidium is pointed at just a single area in space and contributes

information about only one small area in the field of view.

Bistatic radar is the name given to a radar system which comprises a

transmitter and receiver which are separated by a distance that is comparable

to the expected target distance. Conversely, a radar in which the transmitter

and receiver are collocated is called a monostatic radar. A system containing

multiple spatially diverse monostatic radar or bistatic radar components with a

shared area of coverage is called multistatic radar. Many long-range air-to-

air and surface-to-air missile systems use semi-active radar homing which is a

form of bistatic radar.
