Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 115 words
An apparatus for locating a file folder comprising, a portable electromagnetic transmitter having a varied output for providing various selected coded output signals, a shelf for holding a plurality of folders, a plurality of folders positioned on said shelf, each folder having an electrically powered electromagnetic receiver for receiving signals from the transmitter, each receiver providing an output in response to a different coded output signal from the transmitter, signaling means connected to each receiver output for indicating the receipt of signal by a receiver from the transmitter thereby identifying the folder, and said folder includes electrical contacts connected to the receiver, and said contacts adapted to engage and receive power from the power conductors.
Claim 2
Independent Claim 115 words
An apparatus for locating a file folder comprising, a portable electromagnetic transmitter having a varied output for providing various selected coded output signals, a shelf for holding a plurality of folders, a plurality of folders positioned on said shelf, each folder having an electrically powered electromagnetic receiver for receiving signals from the transmitter, each receiver providing an output in response to a different coded output signal from the transmitter, signaling means connected to each receiver output for indicating the receipt of signal by a receiver from the transmitter thereby identifying the folder, and said folder includes electrical contacts connected to the receiver, and said contacts adapted to engage and receive power from the power conductors.
Claim 3
Dependent Claim 13 words
The apparatus of claim 1 wherein the signaling means is a visual signal.
Claim 4
Dependent Claim 14 words
The apparatus of claim 1 wherein the output signal of the transmitter is infrared.
Claim 5
Dependent Claim 35 words
The apparatus of claim 1 wherein said shelf includes electrical power conductors, and said folder includes electrical contacts connected to the receiver, and said contacts adapted to engage and receive power from the power conductors.
Claim 6
Dependent Claim 28 words
The apparatus of claim 1 wherein said transmitter transmits in addition to the coded output a synchronizing pulse signal during each transmitted signal for actuating a said-signaling means.
Claim 7
Dependent Claim 28 words
The apparatus of claim 5 wherein the synchronizing pulse creates a visual blinking signal which is transformed into a steady light when a matching code signal is received.
Claim 8
Dependent Claim 22 words
The apparatus of claim 1 wherein the electrical power conductors on the shelf extend parallel to the longitudinal axis of the shelf.
