PADD
The Personal
Access Display Device has been, and still is, the
best method of transferring and executing data between various
personnel. It is a small handheld control and display terminal,
typically not much larger than a human hand, though larger ones have
been used, and is linked directly to the vessel's main computer. The
device is sufficiently isolated from the ship's computer though, so
that high level computer systems can not be accessed from the PADD.
Virtually all known space faring races have some form of PADD, each
with their own distinctive design attributed to that particular
culture.
It has been theorised, though never attempted, that a properly configured
PADD could allow the user to fly a Starship from anywhere on board the
ship. Though this is obviously impractical, it demonstrates the
versatility of the PADDs.
In its primary role
aboard a Starship, the personal access display device (padd) is a
handheld control and display terminal. Small, easily managed terminals
and computers are in daily use throughout Starfleet, as a natural
response to crew members' needs to (1) execute hardware functions in a
variety of locations, and (2) manipulate visual information and
communicate that information to others aboard ship. Access to
Starfleet computers and other pieces of equipment can be accomplished
through the usual control displays and larger terminal screens, of
course, but the PADD has become a convenient adjunct to those panels
The standard small padd is 10 x 15 x 1 cm and is constructed from
three basic layers of imbedded circuit-composite material. All primary
electronics, including multi-layer display screen, are bonded to the
casing. If dropped accidentally, even from a height of 35 m, a padd
will remain undamaged. Replaceable components are limited to three,
the sarium power loop, isolinear memory chip, and subspace transceiver
assembly (STA) .
In normal daily use, the power supply remains installed and is
induction recharged. A full charge will last sixteen hours; if a padd
is about to exhaust its battery, it can set a memory flag in the main
computer to transfer tasks to a working unit, or suspend them until a
later time. The total memory capacity of the isolinear chips is 4.3
kiloquads. Like the tricorder, the padd can transfer its total memory
to the main computers in less than one second if the need arises. The
STA is used to maintain data channels between the padd and the
Starships computer. If taken on an away mission, the padd can also
perform uplink / downlink operations and function as a transporter
lock-on node. Data transmissions and computing functions can be shared
with any other Starfleet device supporting the STA com protocols. As
with the personal communicator, transmissions are encrypted for
security purposes.
The display screen, 4.25 times larger than that of a tricorder, allows
for the manipulation of control graphics, numerical data, and images
by touch. Electro-sensitive areas of the casing (coloured brown on the
standard engineering padd) are designed for specific data movement and
storage functions. They can also be used to personalize the default
setup and single-crew member security restriction. An audio pickup
sensor permits voice input.
The padd's control functions mimic those of any multi-layer panel,
insofar as the security restrictions for individual crew members are
concerned. Properly configured with the Conn position bridge controls,
a crew member can theoretically fly a starship from a padd while
walking down a corridor.
Custom padd configurations can be fabricated in any starship hardware
replication facility equipped with custom isolinear circuit
programming capabilities.
