Patent number: 4333007Abstract: A system for determining the range to an object utilizing a plurality of radiation responsive detectors arranged in groupings wherein a first grouping of detectors receives radiation from the object in a first pattern and the second grouping of detectors receives radiation from the object in a second pattern. The patterns move with respect to one another as the distance between the object and the system changes. The range is determined from a determination of the relative position of the patterns by computing where the patterns will coincide if the focusing lens of the system is moved. The output is a signal having a characteristic indicative of the desired direction of motion of the lens and a characteristic indicative of the amount of such motion necessary to produce a proper focus condition.Type: GrantFiled: July 10, 1980Date of Patent: June 1, 1982Assignee: Honeywell Inc.Inventors: Richard A. Langlais, Francis T. Ogawa, Dennis J. Wilwerding

Patent number: 4254330Abstract: Apparatus for determining the direction a lens should be moved in order to provide a proper focus of a remote object on a predetermine plane. A plurality of radiation detectors are positioned to receive radiation in first and second patterns from the object and to produce signals in accordance therewith. A first plurality of radiation detectors produces signals indicative of the radiation received in the first pattern while a second plurality of radiation detectors produces signals indicative of the radiation received in the second pattern. The two patterns coincide at the proper focus but at other than the proper focus the two patterns are spaced from one another in a direction which depends upon the direction the lens should be moved to achieve proper focus. The low frequency components in the patterns are determined by taking the sums of the outputs of groups of detectors in the first and second plurality of detectors so that individual fluctuations in individual detectors are smoothed.Type: GrantFiled: September 13, 1979Date of Patent: March 3, 1981Assignee: Honeywell Inc.Inventors: Norman L. Stauffer, Dennis J. Wilwerding

Patent number: 4250376Abstract: Apparatus for determining the direction a lens should be moved in order to provide a proper focus of a remote object on a predetermined plane. A plurality of radiation detectors are positioned to receive radiation in first and second patterns from the object and to produce signals in accordance therewith. A first group of radiation detectors, produces signals indicative of the radiation received on the first pattern while a second group of radiation detectors produces signals indicative of the radiation received, in the second pattern. The two patterns coincide at the proper focus but at other than the proper focus position, the two patterns are spaced from one another in a direction which depends upon the direction the lens should be moved to achieve proper focus.Type: GrantFiled: July 20, 1979Date of Patent: February 10, 1981Assignee: Honeywell Inc.Inventors: James D.

Patent number: 4249073Abstract: A method and apparatus for determining the direction the taking lens of a camera should be moved in order to provide a proper focus condition. A plurality of radiant energy detectors are positioned to receive energy from a scene being viewed and a first group of such detectors produces a first output signal pattern while a second group of such detectors produces a second output signal pattern. The two patterns coincide at the desired focus position but move with respect to one another in a first or opposite direction depending upon the focus condition. The slope of one or both of the patterns at predetermined positions is multiplied by the difference in value from the outputs of the detectors to create values which are summed. The sign of the summed values is representative of the direction the taking lens must be moved to bring the patterns into coincidence at the desired focus position.Type: GrantFiled: March 1, 1979Date of Patent: February 3, 1981Assignee: Honeywell Inc.Inventors: Norman L. Stauffer, Dennis J. Wilwerding
