### device | mechanism | mechanical device | pump:

Vacuum pump
* are electrically powered apparatus
  - oil filled vane type pumps for strong, quick vacuum
  - used to pump air out of the chamber
+ Vacuum, Industrial Vacuum: Matter
  * Vacuum is needed for industrial production. Vacuum pumps are used to pump air out of the chamber. Lower vacuum is mainly used for laboratory purposes.

### device | mechanism | mechanical device | pump | vacuum pump:

Ion pump
* are air pumps
  - clean operating devices
  - important in maintaining cellular integrity
  - membrane proteins that serve both as an enzyme and a channel
* vacuum pump

Water pump
* Many water pumps have a spring-loaded seal to avoid leakage of water around the pump shaft.
* are auto parts
  - bronze or stainless steel
  - used mainly for dewatering purpose to reduce downtime from large rain events
* come in many formats and can be powered from a number of sources of energy.

### device | mechanism | mechanical device:

Simple machine
* Most simple machines are very efficient, but they always lose some efficiency due to friction.
* Some simple machines are a wheel, a pulley, a lever, a screw, and an inclined plane
  - consist of wheels
  - help hold things together
  - use wheels
* are a part of learning about forces and motion
  - designed to make work easier using few parts
  - devices that use energy to make work easier, but have no moving parts
* are simple machines
  - tools used to make work easier
  - the most basic ways of making work easier or more efficient
  - tools that make work easier
  - types of machines that do work with one movement
* are used in everyday life
  - to create a mechanical advantage
* change the effect of the applied force, often reducing work.
* help people do work.
+ Machine: Engineering
  * Often a machine will change one form of energy to another form of energy. Simple machines increase or change the direction of a force.

Splint
* also can help minimize joint destruction
  - prevent any further wearing of the teeth
  - restrict blood flow
* are mechanical devices
  - medical devices
  - more of a condition in young, growing horses
* can help stabilize joints
  - improve functioning for a child
  - stabilize a joint to allow it to rest
* protect during lifting and working.

Vibrator
* are a woman's best friend
  - electrical machines powered by batteries or plugged into electrical outlets
  - located in stores
* can create genital armoring.
* come in three distinct 'types'.

### device | mechanism | mechanical device | vibrator:

Dildo
* Some dildos have macrophallic dimensions including over a dozen inches long
  - vibrate and pivot for extra pleasure
+ Dildo: Sexuality
  * A 'dildo' is a sex toy. It is most often used in place of an actual penis for sexual reasons. Some dildos vibrate and pivot for extra pleasure.

Voting machine
* are complex mechanisms that automatically record and count the votes
* make it difficult for dishonest politicians to influence the count of votes.

Weather vane
* Some weather vanes have directional strips underneath the arrow to make it easier to read.
* are common tools used for measuring the direction of the wind
  - instruments that show the direction of the wind
  - located in roofs
  - mechanical devices
  - used to measure wind's direction
* come in many styles and body shapes.

Wind vane
* determine wind direction.
* point toward the origin of the wind instead of in the direction of the flow.

### device | mechanism | mechanical device | winder:

Bobbin
* are winders.
* come in a variety of sizes and shapes, but they all perform the same duty
  - different lengths and widths

Spool
* are common in drag racing
* studies how people find information on the Web.

Windshield wiper
* Ensure that windshield wipers function efficiently.
* are automotive products
* are part of automobiles
  - cars
  - motor vehicles
