The United States Of America As Represented By The Secretary Of The Air Force’s patent US 5198748 A deals with Frequency measurement receiver with bandwidth improvement through synchronized phase shifted sampling.
A technique covered by the patent applicaton SN 07 / 672,309 divided power of an input signal into two A / D converters. A processor receives the outputs of the two A / D converters. The input signal is subjected to a known delay for one of the converters, and both original and delayed signal examples together. The two sample signal is the Fourier transform, and the pieces, and the size is calculated, using the statement: (f) = tan-1 [(f) / R (f)] A (f) = [R2 (f) + I2 (f)] 1/2 where R (f) and (f) respectively the real and imaginary parts of the frequency change. The phase difference between the original and the delayed signal is calculated and an estimated true frequency for each peak observed in the amplitude spectrum estimated using the expression = 2f where the delay. This is where the input signal is converted into two parallel roads with frequencies different from the FS / 4 where FS is the sampling rate. The alias borders are in multiples of FS / 2 The output signal is divided again into two paths in the form of delayed and undelayed way. The digitized data is processed as part sampling moved way up. Since the four digitizers operated in a uniform speed, the process outputs a clock rate.

The Whalen Thomas E patent solves the following problem:

This invention relates to a Biomedical card containing personal data in medical emergency of a particular man and an inexpensive and simple process to create a Biomedical card completed by the individual described card for maximum ease.

Our analysis of this patent is as follows:

Whalen Thomas E’s patent US 5197763 A deals with Biomedical information card and method of making.
An emergency medical data card for private individual and convenient creation and the process of making it can also be provided in a kit form so that people can make their own emergency medical data card. The emergency medical data card did initially give a blank form that includes indicia individualized, personal information, such as name, address, and a series of medical information indicia includes lines from every word that a man may fill in certain information needed, with particular box to be checked. The letter size form then reduced predetermined amount such that its volume ultimatey is slightly smaller than a credit card opportunity to fit in a purse. The Sheet, once reduced, then attached to a blank rigid plastic card that works as "Emergency Medical Data" on it permanently, all to be laminated together.
