Patent number: 6108031Abstract: A steerable motor vehicle is remotely controlled by a human operator at a remote control station with the operator being supplied with three-dimensional realistic visual representations of scenes in the vicinity of the vehicle to allow him to exercise more accurate control of the vehicle taking into account objects and other features occurring in the environment immediately encountered by the vehicle. The vehicle carries two vehicle cameras for binocularly viewing scenes, and the viewed scenes are transmitted by RF communication links to the remote control station where the scenes are recreated on two display screens, forming part of a virtual reality headset worn by the operator, viewed separately by separate eyes of the operator to create a three-dimensional and realistic impression of the scenes seen by the two cameras.Type: GrantFiled: May 8, 1997Date of Patent: August 22, 2000Assignee: Kaman Sciences CorporationInventors: Michael Arden King, Gary Lee Paderewski

Patent number: 5875264Abstract: A character recognition system employs a "hashing" technique of imaged pixels wherein a digital image constituting an array of pixels is divided into a series of sub-arrays. The sub-array digital signal patterns themselves correspond directly to addresses in associated system memories. Each memory address indicates a predetermined set of the possible characters. There is an apparatus for combining the list of possible characters so that signals corresponding to only one character are output.Type: GrantFiled: September 30, 1996Date of Patent: February 23, 1999Assignee: Kaman Sciences CorporationInventor: David L. Carlstrom

Patent number: 5864365Abstract: A camera housing assembly for protecting a camera from potentially-damaging environmental conditions, such as high temperatures, humidity and corrosive air-borne particulates, has a housing and an internal heat sink received within the housing. The internal heat sink defines a hollow body extending in the elongated direction of the housing and forming an internal chamber for receiving the camera and for transferring heat away from the chamber and camera. A polymeric insulating material is disposed within an annular space formed between the internal heat sink and housing in order to thermally insulate the internal heat sink from the housing. A thermoelectric cooling device extends through an aperture formed in a wall of the housing, and is thermally coupled between the internal heat sink and an external heat sink mounted to an external wall of the housing for transferring heat from the internal heat sink to the external heat sink.Type: GrantFiled: January 26, 1996Date of Patent: January 26, 1999Assignee: Kaman Sciences CorporationInventors: Kurt W. Sramek, John Tinsley

Patent number: 5428530Abstract: A novel airborne reactive threat simulator is presented. The simulator comprises an aircraft flight and carrier qualified podded external store and a cockpit mounted system control box. The pod is capable of supersonic flight envelopes and houses a sophisticated, state-of-the-art, microprocessor controlled, programmable tracking radar system and associated data collection peripherals. The control box provides the operator/machine interface during system operation. The system operates from a library of preprogrammed scenarios, which are selected by the pilot of the aircraft during routine training/testing exercises. A threat simulation scenario is selected by the pilot as the pilot flies a predetermined profile mission against a target ship. The software routine is executed by the microprocessing system which in turn controls all system hardware components and peripherals.Type: GrantFiled: May 5, 1992Date of Patent: June 27, 1995Assignee: Kaman Sciences CorporationInventors: Kevin D. Brown, David D. Hill, Albert C. McGuire

Patent number: 5013908Abstract: A fiber optic detection system comprising an array of fiber optic elements is presented. Each fiber optic element is uniquely encoded using a plurality of discrete ferquencies, digital codes or other encoding techniques. When a break occurs in one or more fiber optic elements, the missing light frequencies or digital codes are sensed, thereby indicating the break. Preferably, the fiber optic elements are arranged in a grid pattern so that precise location of the break can be made.Type: GrantFiled: November 28, 1988Date of Patent: May 7, 1991Assignee: Kaman Sciences CorporationInventor: James Chang

Patent number: 4160204Abstract: This distance measurement system employs the principle of electromagnetic induction to sense distances between an inductive transducer and an object. The inductive transducer forms a part of a signal phase network, and a means for comparing the signal of the inductive transducer to a reference signal provides linear output of the dimension between the transducer and an object. A circuit element such as a capacitor is connected in parallel with the inductive transducer to enhance the sensitivity and resolution of the measurement, to significantly reduce or eliminate error due to temperature, and to provide a high degree of output linearity relative to the distance measured.Type: GrantFiled: November 11, 1974Date of Patent: July 3, 1979Assignee: Kaman Sciences CorporationInventors: William A.
