2340's Combadge

In the late 2350’s the first communicator badge, or commbadge as the device has come to be called, was introduced into the fleets inventory. The outer casing of this commbadge was styled to resemble the fleet insignia badge that had been in use since the 2270’s. In the later part of the 2340’s the commbadge was redesigned to the simpler design of the Delta shield over an oval back ground. In the 2370’s, one hundred years after the first commbadge was put into use the commbadge was once more redesigned and the oval back ground was replaced with a trapezoid background.

It should be noted that the communicator badge is not the first compact communicator put into use by Star Fleet. In the 2250's a Wrist Communicator was introduced to the fleet but due to the limitations of the device it was not widely used and was eventually phased out.

After their introduction the Communicator badge not only replaced the Hand-Held Communicator during away team missions but also became the primary means of communications while on a ship or base facility.

Communicator Badge Operations:

When not in use the communicator badge is in a low powered standby mode. Upon receiving a communication from another user or the badge is activated by the officer it was assigned to the badge switches to the full power operation mode. When the communication is initiated by the badge user they tap the outer casing of the badge to open a subspace communication channel and bring the badge up to full power.

For outgoing communications, the user’s voice is picked up via monofilm pickup and routed to the digital voice encoder were the signal is converted from an analog signal to a digital one. The digital signal is then routed to the encryption circuit for encryption prior to being routed to the subspace field emitter for transmission. For incoming communications, the signal is received via the subspace antenna and then is routed to the encryption circuit before being sent to the voice modulator and then the monofilm pickup.

The communicator badge also serves as a personnel identification device allowing person to be granted access to or restricted from areas of a ship or star base or from accessing data or systems above their assigned access level. The badge also allows the user to be tracked while on any away team mission or while going about their normal duties. This identification function also aids in transporter lock on during transporter operations.

The communicator badge is designed to act as an emergency beacon during emergency situations. This emergency deacon function is automatically activated if the outer casing is damaged to the point of exposing the internal mechanisms.

Communicator Badge Components:

Outer Casing:

The outer casing of the Communicator Badge is fabricated from micromilled duranium overlayered with gold and silver alloys in a diffusion-bonding process.

There is a monoflim pickup mounted to the inner surface of the front section of the casing via diffusion-bonding. This pickup detects the user’s words along with emitting the decoded signal received by the badge.

The passive subspace antenna is mounted to the inner surface back section of the casing. The outer surface of the back section has a micro hook fastener consist of silicon-beryllium alloy hooks inset into it for the purposes of attaching the badge to the users uniform or other such clothing.


Communicator Control Assembly (CCA):

The CCA is composed of three subassemblies, the dermal sensor controller, the encryption circuit assembly, and the universal translator unit. The dermal sensor controller is a cluster of micro sensors that are mounted so they are in contact with the inner surface of the upper casing half. These sensors detect the touch of the user and handle the power level selection for the communicator badge extending the life of the power cell.

The encryption circuit assembly controls the encryption of the outgoing signal along with the decryption of the incoming signal. The encryption algorithms are periodically changed by Starfleet command to ensure ongoing signal security. These algorithms can also be changed at the direction of the commanding officer during away team missions as needed to ensure the security of the away team’s transmissions.

The Universal Translator Unit (UTU) is a simplified version of the standard universal translator. Due to memory storage limitations the UTU is equipped with the basic conversational libraries of 253 galactic civilizations and the linguistic analysis routines for basic translations. Even with these limitations the UTU can handle most of the translation needs of an away team.


Subspace Transceiver Assembly (STA):

The STA incorporates the analog to digital voice encoder along with a low power subspace field emitter. The digital voice encoder is responsible for converting any outgoing signal from an analog to digital signal prior to encryption and transmission. For incoming transmissions, the signal is converted from digital to analog prior to being passed to the monofilm for being emitted as a spoken message.

The subspace field emitter is a wafer of Vertium cortenide that emits a low-level subspace field when energized by power from the power cell. Field strength can be modulated by controlling the amount of power fed into the emitter. This is accomplished via a miniature flow regulator. The digital signal is carried via the emitted field up to distances of 1200 kilometers.


Power Supply:

The power supply for the Communicator Badge is a densified sarium-krellide power cell that is rated for three weeks of continuous use under normal operation conditions. The power cell can be recharged via the standard induction loop charging system or the power cell can be swapped out for a fully charged cell during field operations or other situation were recharging the power cell is not a viable option.
