Did You Know...
...that when IBM conducted a market study of Chester Carlson's invention in 1959, the company concluded that it would take only 5000 units of his new product to saturate the market? IBM therefore declined to be part of the new product introduction. Too bad for IBM. Carlson's invention was the xerography process, and his new product was the beginning of the Xerox Corporation. It is estimated that every day, worldwide, 3,000,000,000 copies are made!!

| Number | Title | Issue Date |
| 4068234 | Frequency scanned illumination imaging array Disclosed herein is an imaging system comprising a linear array of receivers and a single transmitter deployed and operated in such a manner as to produce the equivalent of a completely filled, two-dimensional array.... | 01/10/1978 |
| 4040056 | Method for aberration-free optical recording of highly resolved sonar or radar maps A method for aberration free optical recording of highly resolved sonar or radar maps wherein a series of one-dimensional holograms is recorded as a function of the receiving time with the help of pulsed sonar or radar and is coherently optically reconstr... | 08/02/1977 |
| 4024539 | Method and apparatus for flight path control Signals from a source of flight path data, normally a memory device which stores forward-looking radar data, for example, are sampled in "reverse-time". That is, the data points along the flight path are taken in reverse order relative to the direction of... | 05/17/1977 |
| 4023173 | Object discerning method and apparatus using a spatial wave propagation Disclosed is a method and apparatus for holographically discerning an object, using any kind of coherent wave such as microwave, millimeter wave, or sound wave. An asymmetric, dispersive medium is so positioned that some of the coherent wave scattered by ... | 05/10/1977 |
| 4023175 | Imaging systems Echo data relating to the distance away of reflective elements of an object surface is received by an array of receivers. A signal processing device receives the data and together with information as to the range of the object surface defines equitime loc... | 05/10/1977 |
| 4011445 | Optical array active radar imaging technique An optical target imaging system having a laser transmitter that provides a dual pulse sequence target illuminating field. One pulse of the dual pulse field is predominantly polarized in one direction and the other pulse is predominantly orthogonally pola... | 03/08/1977 |
| 4005258 | Ultrasonic examination A device for examination by ultrasonic pulses to produce better image resolution, of the type including the formation of a B-type intermediate image of the object examined on the target of a recording tube, the reading of this image by television type sca... | 01/25/1977 |
| 3988731 | Augmented perspective radar display Control circuits are provided in a perspective radar display to modify the vertical sweep wave form voltage function on the display cathode ray tube to correspond to the sweep function which would be provided if the observer and radar antenna were at a di... | 10/26/1976 |
| 3986160 | Visualization by ultrasonic detection A system for sensing by ultrasonic vibrational energy the shape and character of objects immersed in a visually opaque transmission medium is disclosed. Frequency modulated ultrasonic waves are projected to irradiate an object, with reflected energy from ... | 10/12/1976 |
| 3953822 | Wave-energy imaging technique A circumferential array of n transducers is used to image an object with resolution equal to that of an array over the entire bounded aperture. This is done by illuminating the object with m components of coherent wave energy, and coherently detecting the... | 04/27/1976 |
| 3942150 | Correction of spatial non-uniformities in sonar, radar, and holographic acoustic imaging systems An improved method and apparatus for processing electronic signals for use n establishing an improved image display includes storing the electronic and acoustic response of all the detectors in response to impingement thereon by a plane wave-front as store... | 03/02/1976 |
