Abstract
Abstract A data entry system suitable for entry/exit (attendance) recording includes a terminal unit having identity card reading means, adapted to be connected via an extension line to a central apparatus such as a computer controlled telephone line switching system having data handling capabilities. The terminal unit includes a buffer to store the data read from the identity card prior to requesting service from the line switching system and includes a locally generated signal to indicate that the card was correctly read and means responsive to a signal from the central system to indicate that the data was accepted. The card forms a component of the system and is encoded in such fashion that the manner of its use indicates whether entry or exit information is being recorded, and the terminal unit is responsive to the information entered by the card and the response of the central system to provide appropriate logical output at the terminal, such as the activation of an automatic door lock.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
208 words
In the data entry system, a central system and a terminal comprising means adapted to accept entry of data for transmission to said central system, the improvement wherein said terminal comprises: first indicator means comprising latch means and means responsive to the accepting means in the terminal to set said latch means by and upon the acceptance of data by said accepting means, said indicator means comprising first sensible means connected to said latch means to be operated upon and for the duration of the set condition of said latch means to indicate to a user of the terminal that the data has been accepted by the terminal, means in the terminal operative to activate a connection of the terminal to said central system for said transmission thereto and to receive a data response signal from the central system, and second indicator means in the terminal responsive to said connection and active by and upon receipt of said data response signal from said central system to reset said latch means, said second indicator means comprising a second sensible means operative to provide an indicator signal distinguishable from that of said first sensible means and operable by and upon said receipt of said response signal by the central system.
Claim 2
Dependent Claim
208 words
In the data entry system, a central system and a terminal comprising means adapted to accept entry of data for transmission to said central system, the improvement wherein said terminal comprises: first indicator means comprising latch means and means responsive to the accepting means in the terminal to set said latch means by and upon the acceptance of data by said accepting means, said indicator means comprising first sensible means connected to said latch means to be operated upon and for the duration of the set condition of said latch means to indicate to a user of the terminal that the data has been accepted by the terminal, means in the terminal operative to activate a connection of the terminal to said central system for said transmission thereto and to receive a data response signal from the central system, and second indicator means in the terminal responsive to said connection and active by and upon receipt of said data response signal from said central system to reset said latch means, said second indicator means comprising a second sensible means operative to provide an indicator signal distinguishable from that of said first sensible means and operable by and upon said receipt of said response signal by the central system.
Claim 3
Dependent Claim
16 words
Apparatus in accordance with claim 1 wherein said sensible indicator means comprise separate indicator light means.
Claim 4
Dependent Claim
53 words
Apparatus in accordance with claim 2 wherein said terminal includes a time-out means, and means responsive to said accepting means to initiate said time-out means, and means operative to reset said latch means upon the occurrence of either time-out of said time-out means or said receipt of said response from the central system.
Claim 5
Dependent Claim
42 words
Apparatus in accordance with claim 3, wherein said second indicator means includes driver means for said second sensible means responsive to and maintained in active state during said response signal from the connected central system indicating a predetermined response to said data.
Claim 6
Dependent Claim
43 words
Apparatus in accordance with claim 4, wherein said time-out means includes means coupled to said connection and operAtive to reinitiate the time-out period of said time-out means by and upon the occurrence of each said data response signal from the connected central system.
Claim 7
Dependent Claim
96 words
In a data entry system, a data entry terminal, a central data handling system, and a data transmission channel interconnecting said terminal with said central system, said channel comprising a normally inactive extension connected to said terminal, first means in said terminal responsive to data entry employment thereof to switch said extension to active state, said first means including a time-out means operative to maintain said active state for a predetermined time, and second means in said terminal responsive to a data response signal from the central system via said channel to reinitiate said time-out means.
Claim 8
Dependent Claim
96 words
In a data entry system, a data entry terminal, a central data handling system, and a data transmission channel interconnecting said terminal with said central system, said channel comprising a normally inactive extension connected to said terminal, first means in said terminal responsive to data entry employment thereof to switch said extension to active state, said first means including a time-out means operative to maintain said active state for a predetermined time, and second means in said terminal responsive to a data response signal from the central system via said channel to reinitiate said time-out means.
Claim 9
Dependent Claim
44 words
A system in accordance with claim 6, wherein said data entry terminal is an entry/exit reporter terminal adapted for employment by multiple users in succession, said second means including logical decoder means adapted to interpret said signal as a central system data response signal.
Claim 10
Dependent Claim
95 words
A system in accordance with claim 7, wherein said central system comprises a line switching system and activation of said extension constitutes an off-hook signal thereto, requesting service, said terminal further including buffer means adapted to store data entered into said terminal, and sequencer means responsive to said logical decoder means to gate said data from said buffer to said channel, said logical decoder being responsive to said time-out means to interpret each second and successive signal received from said central system during the active state of said time-out means as a data response signal.
Claim 11
Dependent Claim
169 words
A data entry terminal for use in a data entry system comprising at least one terminal for receiving data and a central controller for controlling said terminal, said terminal comprising: an information input for receiving and buffering data from a terminal user; an input indicator connected to said information input and having an active state to indicate to said user that said data has been received and buffered; said information input including settable means operative to maintain said operative state of said input indicator; connecting means connected to said information input and to an operating means to connect said terminal to said central controller for transmitting said data to said central controller and transmitting a response from said central controller to said operating means; and an operation indicator connected to said operating means to indicate to said user that said controller has responded to said input data, said settable means being connected to said operating means to thereupon be reset to terminate said operative state of said input indicator.
Claim 12
Dependent Claim
