Patent number: 4680626Abstract: A color image processing system is described which provides more realistic hard copy color images from composite video system input signals than previously available. The image processing system includes a synchronization separator 20 which operates to separate the synchronization pulses from the analog video information supplied to it. The analog video information is then converted to digital form by an analog-to-digital converter. The converter operates under control of a time base generator 100, including a programmable delay line 300, which receives synchronization pulses from the synchronization separator, and following a programmable time delay supplies a control pulse to the converter to cause it to sample the analog waveform and convert it to digital format. Once the signal is digitized, it is converted from an additive color system to a subtractive one end enhanced before being supplied to the color plotter 8.Type: GrantFiled: April 9, 1985Date of Patent: July 14, 1987Assignee: Benson, Inc.Inventors: Michael F.

Patent number: 4672450Abstract: An image processing system includes a synchronization separator 20 which operates to separate the synchronization pulses from the analog video information supplied. The separator includes an amplifier with a pair of input terminals. The video is coupled to one of the input terminals and a feedback loop coupled between an output terminal and the other input terminal. In this manner the negative synchronization pulses may be amplified while the positive video signals are limited. The extracted sync signal is used to control an analog-to-digital converter 70. The analog video information is then converted to digital form by an analog-to-digital converter. The converter operates under control of a time base generator 100, including a programmable delay line 300, which receives synchronization pulses from the synchronization separator, and following a programmable time delay supplies a control pulse to the converter to cause it to sample the analog waveform and convert it to digital format.Type: GrantFiled: April 9, 1985Date of Patent: June 9, 1987Assignee: Benson, Inc.Inventor: Galen Collins

Patent number: 4631740Abstract: A color image processing system is described which provides more realistic hard copy color images from composite video system input signals than previously available. The analog video information is converted to digital form by an analog-to-digital converter. The converter operates under control of a time base generator (100). The time base generator (100) provides more accurate control over the converter than the system clock signal. The generator (100) receives pulses from the synchronization separator, and following a programmable time delay supplies a control pulse to the converter to cause it to sample the analog waveform and convert it to digital format. The generator (100) employs a delay line (300) to detect the fraction of a system clock period between the sync pulse and the next clock pulse. The specified number of clock pulses are allowed to elapse. Then the delay line (300) is used to provide the necessary further delay.Type: GrantFiled: April 9, 1985Date of Patent: December 23, 1986Assignee: Benson, Inc.Inventor: Galen Collins

Patent number: 4498737Abstract: A structure for focusing, collimating or diverging the light beam from a solid state laser diode comprises means non-symmetrically mounted between the structure for holding the lens system and the means for holding the laser diode thereby to allow the laser diode to be adjusted in position relative to the lens system along the optical axis of the lens system. Surprisingly, the non-symmetrical mounting of the adjusting means relative to the optical axis of the lens system does not cause any substantial transverse movement of the laser diode relative to the optical axis of the lens system. In one embodiment, the adjusting means comprises a screw rotatably mounted such that one end of the screw is rotatably screwed into with the structure holding the lens system and the other end of the screw is in rotatable contact the structure holding the laser diode.Type: GrantFiled: February 26, 1982Date of Patent: February 12, 1985Assignee: Benson Inc.Inventor: David E.

Patent number: 4478480Abstract: An optical laser scanning system includes a hologram spinner disc (32) having diffraction grating facets (33) around its periphery. The spinner is susceptible to wobble and translational movement of the facets with respect to a plane perpendicular to the disc axis (35). Corrective means (37) in the form of a ray converging element (37) are provided to collect parallel diffracted rays from the facets in translated positions of wobble and converge such rays to a spacial spot scan (38) on an imaging surface (40). By orienting the spinner such that the diffracted light beam makes a 90.degree. angle with the incident light beam and then providing a parabolic cylinder to direct and focus the diffracted light beam on the imaging surface, the effects of both translational and angular wobble on the image formed are eliminated.Type: GrantFiled: December 27, 1982Date of Patent: October 23, 1984Assignee: Benson, Inc.Inventor: David E.

Patent number: 4417391Abstract: A recording head for use in an electrostatic printer comprises four staggered rows of styli formed by a novel method wherein the styli in the second row are formed between the styli in the first row and the styli in the third and fourth rows are formed by making use of the grooves formed between the styli in the first and second rows. By forming the rows of styli on a cylindrical drum, two recording heads are obtained from each fabrication run wherein the recording head in one set of styli is the mirror image of the recording head in the other set of styli. Should an error occur in the manufacture of the styli by placing the third row of styli in the grooves where the fourth row of styli normally belongs, the resulting recording heads are identical to those obtained with the proper placement of the third and fourth rows with the exception that the position on the drum of each type of recording head is reversed.Type: GrantFiled: June 8, 1982Date of Patent: November 29, 1983Assignee: Benson, Inc.Inventors: Sherman L.
