Abstract: ABSTRACT OF THE DISCLOSURE          An electrical modular roadway system adapted for transmitting power to and controlling inductively coupled vehicles  traveling  thereon.  The  system  comprises  a plurality of elongated, electrically connected   inductor modules arranged in an aligned end to end spaced apart order to form a continuous vehicle path. Each module has a magnetic core and power windings which generate a magnetic field  extending  above  the  road  surface.  Controllable relays  are  connected  between  modules  for  allowing operating electric current to either activate or bypass selected  modules.  Sensing  windings  in  modules  are activated by the presence of  a  vehicle  on one module to provide control signals to  relays for other modules.

Title: Phase locked frequency synthesizer with single input gain compensated wideband modulation system
Inventor: VANDEGRAAF JOHANNES J
IPC: H03C3/00
Filed: 1989-06-01
Granted: 1992-11-17
Abstract: PHASE LOCKED FREQUENCY SYNTHESIZER WITH SINGLE INPUT GAIN COMPENSATED WIDEBAND MODULATION                     SYSTEM    ABSTRACT    Several embodiments are disclosed of a modulation equalization network associated with a phase locked loop to achieve frequency independent modulation of the VCO.  The equalization network is disposed to introduce the modulation signal into the control loop ahead of the loop filter but after the phase detector output.  The interposed equalization network requires only a single input port to achieve a flat modulation response thereby lending itself to a modular implementation.  The modulation processing is performed totally outside the phase locked loop.          The network serves to provide a boost to low frequency signals from the modulation source using an integrator network while providing a high frequency response that is essentially the inverse of the phase locked loop filter response.

Title: Near obstacle detection system
Inventor: MAY PHILLIP A
IPC: G01S13/931
Filed: 1989-06-16
Granted: 1996-07-23
Abstract: In a radar system for alerting the vehicle operator of obstacles behind the vehicle when backing up or in front of the vehicle below the operator's line of sight an RF signal is transmitted at a frequency modulated by a sawtooth signal.  The transmitted RF signal is mixed with the transmitted signal reflected from an object.  The resulting IF signal is analyzed into a Fourier series having a DC coefficient and harmonic frequency coefficients.  The range to the object is determined from the harmonic frequency coefficients in multiples of the range resolution determined by the RF bandwidth of the system when the DC coefficient is less than each of the harmonic frequency coefficients.  The range to the object is determined to be within 1/2 the range resolution determined by the RF bandwidth when the DC coefficient is greater than each of the harmonic frequency coefficients.

Abstract: ABSTRACT OF THE INVENTION    An A/D converter circuit generates a precise digital signal which accurately corresponds to an analog input signal.  The A/D converter comprises a converter element, having a first and second, input terminal for receiving control signals, and having an output terminal, and further having at least one analog input terminal.  The analog input signal is coupled to the analog input terminal, for converting the analog input signal to an uncorrected digital signal.  The uncorrected digital signal includes inaccuracies of the parameter differentials of the converter element.  A memory unit, stores information defining the actual parameter values of the converter element.  A processor, controls the conversion of the analog input signal to the precise digital signal, wherein the actual parameter values are applied to the uncorrected digital signal thereby removing the inaccuracies of the converter element to obtain the precise digital signal.
