 | PADD (Acronym for Personal Access Display Device) |  |
|---|
|
|---|
 A hand-held access terminal to a computer system. PADDS are equipped with a display and touch sensitive areas and have limited built-in memory and computing capability. They are employed to establish uplinks and downlinks to computer systems and may serve as transporter locks-ons. Apart from Starfleet, PADDs are used by most other advanced civilizations.

| Pattern buffer | |
|---|
|
|---|
Part of the transporter system, usually located on the deck below the transporter platform. The pattern buffer is used for short-term storage of the matter stream, thereby providing a delay necessary to compensate for relative velocity (Doppler compensator), filter out hazardous organic materials (biofilter) or transfer the pattern to another pattern buffer in case of a transporter malfunction.

| Pattern enhancer | |
|---|
|
|---|
 Pattern enhancers are one of the main tools developed to safely increase the range and effectiveness of transporter systems. The devices are used to boost the molecular pattern of an object or lifeform so that the pattern lock for transportation is stronger and more defined. These instruments are usually only needed in order to overcome interference caused by electromagnetic shielding or naturally-occurring phenomena.
Pattern enhancers were introduced in Starfleet around 2369 and are portable cylinders about a metre tall, and are normally used in groups of three. They are chrome-colored, with a clear narrow dome on top that lights up when activated. A switch in the midsection releases three legs from the base, allowing the unit to stand alone and remain balanced on uneven ground.
The apparatus is activated by twisting the dome and the black casing just below it anti-clockwise. When deployed, typically seven metres apart in a triangle formation, the clear top acts both as an emitter and and as a conductor for the thin blue energy beam that connects all three units. For ease of portability, a hinged tri-fold case wraps around the midsection of a set of three cylinders. The squarish case includes a carrying handle and a recessed, moulded interior to cushion and protect the enhancers from knocks.
Once the last unit of three has been activated, a beam of blue energy joins all the units together and defines the space either in which the matter to be transported must be placed or the area where persons or objects are to be materialised.
Under normal conditions, the shipboard transporter does not require a receiver or transmitter at the other end. Sometimes, however, pattern enhancers have to be taken to the required destination on a small shuttlecraft where space is at a premium, and therefore the equipment is made light and easy to carry so that they are mobile devices that can be easily operated. This specialized apparatus is often used to compensate for interference caused by electromagnetic storms or other atmospheric disturbances, and make transporting safer by amplifying the transporter signal lock. They are often carried by rescue teams sent into hazardous environments.
Pattern enhancers are primarily safety equipment, ensuring a safe transporter signal in otherwise hazardous conditions. Before their invention, beaming up from certain planetary conditions could be dangerous and potentially fatal. |

| Phaser (Acronym for PHASed Energy Rectification) | |
|---|
|
|---|
Energy discharge weapon used by the Federation. Energy stored in the Phaser is released within a short time and directed towards the target, unlike the usually constant energy output of lasers. The phaser's function is based on the rapid nadion effect, where nadions are subatomic particles that allow to liberate strong nuclear forces.
Phaser beams travel at light speed, and the maximum efficient operation range is 300,000km. Hand-held phasers are available in different sizes, ranging from small pocket phasers (type 1) and pistols (type 2) to phaser rifles. Since phasers have to be recharged, it is obvious that continuous firing is not possible, neither with a hand-held device, nor with the shipboard phasers.

|

| Plasma | |
|---|
|
|---|
Ionized gas, often regarded as the forth state of matter besides the solid, fluid and gaseous state. Consisting of charged particles, plasma is electrically conductive. Due to this property and the fact that the excited electrons in a plasma are on higher energy level than bound electrons in other forms of matter, plasma is suited to transport energy. In particular, plasma is employed to provide the necessary energy for the warp drive and other systems of a starship. The EPS serves to distribute plasma throughout the ship. The continuously occuring relaxation of excited electrons from a higher to a lower energy level becomes obvious in a characteristic glow.

Highly energetic but unstable power source. Although early research showed polaric energy as a promising means of providing power on a planetary scale, its use ran serious risks of uncontrolled chain reactions through subspace.
