engineering component |
A fundamental concept that applies in many engineering domains. An EngineeringComponent is an element of a Device that is a physically whole object, such as one might see listed as standard parts in a catalog. The main difference betweeen EngineeringComponents and arbitrary globs of matter is that EngineeringComponents are object-like in a modeling sense. Thus, an EngineeringComponent is not an arbtrary subregion, but a part of a system with a stable identity.

antenna | A CommunicationDevice which enables or improves the reception of RadioEmissions by another CommunicationDevice (the radio or television receiver). |
| | broadcasting station | A BroadcastingStation is an engineeringSubcomponent of either a TelevisionSystem or a RadioStation. |
| | modem | A CommunicationDevice capable of bidirectional data transmission over a WireLine that was designed to be a TelephoneLine. |
| | communication appliance | A HouseholdAppliance that can be used for comumication (conjuction with CommunicationDevice). |
| | communication radio | Relatively low power broadcasting devices designed for voice communication among specialized groups in which each receiver also has the power to transmit, unlike broadcast radio where most components transmitting or receiving on a given frequency or set of frequencies are receivers only. This includes unlicensed walkie_talkies, public safety radios, military communication systems and CB radios. |
| | communication satellite | A CommunicationSatellite is an ArtificialSatellite that serves as one engineeringSubcomponent of a CommunicationSystem. |
| | data display device | An instance of DataDisplayDevice is a Device intended to be used to display data information in some visual form (e.g., Images or visible LinguisticExpressions). |
| | fax machine | A FaxMachine is a TelephonyDevice that scans a paper page and transmits a coded image of the page over a TelephoneSystem to a receiving FaxMachine, which decodes the coded and image and prints a replica of the original. A typical FaxMachine is made up of a scanner, a printer, a modem, and a control panel with some sort of status display. |
| | IM client | This represents an InstantMessaging client such as Trillian, Pidgin, or Google Talk. The client is a platform on which two or more computers can communicate. Note that an IM client is not necessary for InstantMessaging to occur, as many web sites can support instant messaging without the need to download a client. |
| | main telephone line | A MainTelephoneLine is one engineeringSubcomponent of a TelephoneSystem used for voice communication or computer data transfer. |
| | microphone | A CommunicationDevice that converts sound into electrical energy. |
| | network router | A CommunicationDevice that forwards data packets between Computers or computer networks. |
| | projection screen | A CommunicationDevice upon which images are projected so that they can be viewed. |
| | receiver device | An ElectricDevice that is capable of receiving and decoding RadioEmissions, e.g. Radios and Televisions. |
| | telegraph | A Device that permits LinguisticCommunication between remote points by means of a code of aural dots and dashes that can be converted into letters of an alphabet. |
| | telephone | A Telephone is a CommunicationDevice that enables LinguisticCommunication between nodes in a TelephoneSystem by converting sound into electrical signals that are then transmitted. When the signals are received, they are converted back into sound. |
| | telephony device | A TelephonyDevice is a CommunicationDevice that, when connected to a TelephoneSystem, functions as an access point allowing end users (Humans or other Agents, such as autonomous/scheduled ComputerPrograms) to send or receive signals via the system. Telephones and FaxMachines are TelephonyDevices. A given Computer may or may not function as a TelephonyDevice, depending on the ComputerPrograms it runs and the ComputerComponents that are part of it. |
| | telex | Telex is a Telegraph_like CommunicationDevice that is used to send messages over a TelephoneSystem. |
