Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
183 words
An electronic device for recording and displaying information regarding the arrival and departure of personnel at a location, comprising: (a) a frame; (b) a series of manually operable personnel indicating switches exposed on the frame, each of such switches representing a particular person or persons on different shifts in respect of which information is to be recorded or displayed, each of these switches only being actuable exclusively of the others; (c) a further series of manually actuable time indicating switches exposed on the frame, each of such switches representing a particular time, and each of such switches only being actuable exclusively of the others; (d) memory means electrically associated with the personnel indicating and time indicating switches to receive and store information received from these switches; (e) means electrically associated with the memory means and personnel indicator switches, and actuable upon selection of a personnel indicating switch, to retrieve information stored in the memory means with respect to that person and display it at a time display means visibly located on the frame; and (f) switch means to actuate the information retrieval means.
Claim 2
Dependent Claim
183 words
An electronic device for recording and displaying information regarding the arrival and departure of personnel at a location, comprising: (a) a frame; (b) a series of manually operable personnel indicating switches exposed on the frame, each of such switches representing a particular person or persons on different shifts in respect of which information is to be recorded or displayed, each of these switches only being actuable exclusively of the others; (c) a further series of manually actuable time indicating switches exposed on the frame, each of such switches representing a particular time, and each of such switches only being actuable exclusively of the others; (d) memory means electrically associated with the personnel indicating and time indicating switches to receive and store information received from these switches; (e) means electrically associated with the memory means and personnel indicator switches, and actuable upon selection of a personnel indicating switch, to retrieve information stored in the memory means with respect to that person and display it at a time display means visibly located on the frame; and (f) switch means to actuate the information retrieval means.
Claim 3
Dependent Claim
92 words
An electronic device according to claim 1 further comprising in-out indicating switches electrically associated with the memory means to provide a signal thereto with respect to the presence or absence of a particular person, the memory means to additionally receive and store such signal received from such switches, the device further comprising in-out display means electrically associated with the memory means and information retrieval means, whereby such information stored in the memory means with respect to a particular person in-out status is visibly displayed upon actuation of the information retrieval means switch.
Claim 4
Dependent Claim
47 words
A device according to claim 2 wherein the memory means comprises a series of latching circuits, one for each person in respect of which information is to be recorded, each latching circuit to be output enabled and input gated by actuation of its corresponding personnel indicating switch.
Claim 5
Dependent Claim
14 words
A device according to claim 3 wherein each latch is a D-type flip flop.
Claim 6
Dependent Claim
50 words
A device according to claim 3 wherein the time indicating switches are momentary push-buttons which, when actuated, set the circuit of the latch for a particular selected person to the proper output so as to provide a corresponding time display at the time display means for that particular selected person.
Claim 7
Dependent Claim
36 words
A device according to claim 1 wherein the time display means consists of a series of LED's, one for each position in time sought to be displayed and corresponding to each of the time indicating switches.
Claim 8
Dependent Claim
33 words
A device according to claim 5 wherein the in-out display means comprises two LED's, one for "in" status and one for "out" status, and each corresponding to the respective in-out status selector switch.
