Abstract
Abstract An electronic device for determining the relative speed between two units-vehicles or the like-by utilizing the Doppler effect. A transmitter would be located in one vehicle to transmit on a given frequency but also to transmit an encoded number corresponding to the transmitting frequency. The receiver, by detection of the shift between the coded number and the received frequency would determine the relative speed between the transmitter and the receiver.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
A device for measuring relative speed between two units comprising: a. Oscillator means to generate a carrier wave, b. Means connected to said oscillator means to receive impulses of said wave and measure and encode the frequency thereof and to impose such encoded frequency on said wave and to transmit it, and c. Receiver means to receive said wave including means to distinguish said encoded frequency, means to measure the received frequency, both of said last-named means being connected to computer means, said computer means being adapted to compare the encoded frequency with the received frequency to compute the relative velocity therefrom.
Claim 2
Independent Claim
102 words
A device for measuring relative speed between two units comprising: a. Oscillator means to generate a carrier wave, b. Means connected to said oscillator means to receive impulses of said wave and measure and encode the frequency thereof and to impose such encoded frequency on said wave and to transmit it, and c. Receiver means to receive said wave including means to distinguish said encoded frequency, means to measure the received frequency, both of said last-named means being connected to computer means, said computer means being adapted to compare the encoded frequency with the received frequency to compute the relative velocity therefrom.
Claim 3
Dependent Claim
42 words
The device of claim 1 in which said means connected to said oscillator means includes dual branches, one branch including frequency measuring and encoding means and the other branch including delay means whereby the encoded frequency is imposed on waves generated simultaneously.
Claim 4
Dependent Claim
25 words
The device of claim 2 in which identification means is also connected to the encoding means whereby coded identification is also imposed on said wave.
Claim 5
Dependent Claim
20 words
The device of claim 1 in which said receiver includes display means whereby said velocity is displayed to an operator.
Claim 6
Dependent Claim
24 words
The device of claim 3 in which said receiver includes a display means whereby said velocity and identification is made evident to an operator.
Claim 7
Independent Claim
49 words
The method of measuring relative velocity between a wave source and a receiver which comprises generating a carrier wave, imposing the counted frequency of said wave as encoded intelligence on said wave and comparing the encoded intelligence with the counted frequency of the wave as received by said receiver.
Claim 8
Independent Claim
49 words
The method of measuring relative velocity between a wave source and a receiver which comprises generating a carrier wave, imposing the counted frequency of said wave as encoded intelligence on said wave and comparing the encoded intelligence with the counted frequency of the wave as received by said receiver.
Claim 9
Dependent Claim
25 words
The method claimed in claim 6 in which said counted frequency is imposed on the wave generated simultaneously with the wave whose frequency is counted.
Claim 10
Dependent Claim
20 words
The method of claim 6 in which identification information is also imposed on said wave and discriminated by said receiver.
