Abstract
Abstract A modular terminal comprising a frame, a data distribution chamber, a power distribution apparatus and plural functional units. The functional units are supported and oriented by the frame in such a way that each interconnects with the power distribution components. Functional units communicate via optical transmissions through the data distribution chamber. This allows a functional unit to be inserted, removed or moved from one frame location to another without special equipment or tools by unskilled personnel.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
223 words
An interactive modular terminal including: a. a frame having a plurality of openings therein, said openings being operable for orienting and retaining one or more self-contained functional units with some of the units being operable for interfacing with a human operator to provide communication of information between the functional units and the operator, b. one or more self-contained functional units, operable to perform an included function, being fitted in the openings and being supported in said frame with each of said self-contained functional units having: (1) a signal transceiver for receiving and transmitting data signals, (2) a logic unit for processing received signals to cause the included function to be performed, (3) a power tap for transferring power to said signal transceiver and said logic unit, c. a data distribution chamber in communication with the signal transceivers of each self-contained functional unit for providing a communications medium linking each functional unit with at least one other functional unit, and d. a power distribution means for distributing power among one or more of said self-contained functional units and including: (1) a pattern of current conductors and adapted to be conductively connected to said power taps, (2) one or more openings being positioned in the power distribution means and operable to form a signal communicating path between the data distribution chamber and the signal transceivers.
Claim 2
Dependent Claim
223 words
An interactive modular terminal including: a. a frame having a plurality of openings therein, said openings being operable for orienting and retaining one or more self-contained functional units with some of the units being operable for interfacing with a human operator to provide communication of information between the functional units and the operator, b. one or more self-contained functional units, operable to perform an included function, being fitted in the openings and being supported in said frame with each of said self-contained functional units having: (1) a signal transceiver for receiving and transmitting data signals, (2) a logic unit for processing received signals to cause the included function to be performed, (3) a power tap for transferring power to said signal transceiver and said logic unit, c. a data distribution chamber in communication with the signal transceivers of each self-contained functional unit for providing a communications medium linking each functional unit with at least one other functional unit, and d. a power distribution means for distributing power among one or more of said self-contained functional units and including: (1) a pattern of current conductors and adapted to be conductively connected to said power taps, (2) one or more openings being positioned in the power distribution means and operable to form a signal communicating path between the data distribution chamber and the signal transceivers.
Claim 3
Dependent Claim
53 words
The apparatus of claim 1 wherein: said pattern of current conductors includes plural conductive rails supported by said frame and said power tap includes a contact for electrically contacting at least one of said rails when an associated functional unit is supported in one of a selected plurality of openings in said frame.
Claim 4
Dependent Claim
52 words
The apparatus of claim 1 wherein said functional units include one or more of: a. an input functional unit including a keyboard, b. an output functional unit including a visual display, c. an output functional unit including a hard copy printer, d. a controller functional unit, e. a power supply functional unit.
Claim 5
Dependent Claim
25 words
The apparatus of claim 1 wherein at least some of said functional units include a digital microprocessor connected to a transceiver of said functional unit.
Claim 6
Dependent Claim
19 words
The apparatus of claim 1 wherein each said transceiver includes: an optical energy transmitter, and an optical energy detector.
Claim 7
Dependent Claim
18 words
The apparatus of claim 5 in which said transceiver transmits and receives infrared or other wavelengths optical energy.
Claim 8
Independent Claim
25 words
The apparatus of any of claims 1-6 in which said data distribution chamber includes diffusing means for diffusing energy from any transceiver throughout the chamber.
Claim 9
Dependent Claim
17 words
The apparatus of claim 5 wherein said optical energy transmitter has a relatively wide field of view.
Claim 10
Dependent Claim
25 words

Claim 11
Dependent Claim
25 words
The apparatus of claim 2 wherein said rails are supported by said frame in a horizontal plane defined by the uppermost extremities of said frame.
Claim 12
Dependent Claim
84 words
The apparatus of claim 1 further including a first set of openings positioned in the frame and operable to enable the power tap on each functional unit to coact with the power distribution means; and a second set of openings positioned in the frame and in alignment with the openings in said power distribution means whereby the second set of openings and the openings in said distribution means coact to form a signal communicating path between the data distribution chamber and the signal transceivers.
Claim 13
Dependent Claim
161 words
A modular terminal including: a. a frame having a plurality of openings therein for orienting and retaining one or more self-contained functional units; b. one or more self-contained functional units operable to perform an included function, each of said functional units supported in said frame and having: (1) a signal transceiver for receiving and transmitting data signals, (2) a logic unit for processing received signals to cause the included function to be performed, (3) a power tap for transferring power to said signal transceiver and said logic unit, c. a distribution means being placed in spaced relationship with the frame and operable for distributing power and informational signals among one or more of said functional units; and d. a data distribution chamber abutting on the frame and in communication with the signal transceivers of each functional unit via openings being provided in the distribution means for providing a communications medium linking each functional unit with at least one other functional unit.
