Abstract
Abstract A device assists in target acquisition by an operator in a weapon system comprising a target detection and locating system that delivers target-locating data, said device comprising means to synthesize stereophonic signals intended for the operator and means to convert target-locating data into data controlling the synthesis of stereophonic signals so that the operator is given a subjective sensation of a direction of attack corresponding to the actual direction of the target with respect to this operator.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
114 words
A device to provide an operator with target acquisition assistance in a weapon system comprising a target detection and locating system that delivers target-locating data, said device comprising means to synthesize stereophonic sound signals intended for the operator, and means to convert said target-locating data into control data for a synthesis of stereophonic signals so that the operator gets a subjective sensation of a direction of attack corresponding to an actual direction of a target with respect to said operator, wherein the target-locating data comprise direction data indicating the actual direction of said target and wherein said direction data is combined, after conversion, with data indicating a direction in which the operator is looking.
Claim 2
Independent Claim
114 words
A device to provide an operator with target acquisition assistance in a weapon system comprising a target detection and locating system that delivers target-locating data, said device comprising means to synthesize stereophonic sound signals intended for the operator, and means to convert said target-locating data into control data for a synthesis of stereophonic signals so that the operator gets a subjective sensation of a direction of attack corresponding to an actual direction of a target with respect to said operator, wherein the target-locating data comprise direction data indicating the actual direction of said target and wherein said direction data is combined, after conversion, with data indicating a direction in which the operator is looking.
Claim 3
Independent Claim
124 words
A device to provide an operator with target acquisition assistance in a weapon system comprising a target detection and locating system that delivers target-locating data, said device comprising means to synthesize stereophonic sound signals intended for the operator, and means to convert said target locating data into control data for a synthesis of stereophonic signals so that the operator gets a subjective sensation of a direction of attack corresponding to an actual direction of a target with respect to said operator, wherein said means for synthesizing stereophonic sound signals comprises a read only memory containing binary signals that correspond to a given target, an output of said memory being applied to a digital/analog converter which has its own output applied to two stereophonic amplifiers.
Claim 4
Independent Claim
124 words
A device to provide an operator with target acquisition assistance in a weapon system comprising a target detection and locating system that delivers target-locating data, said device comprising means to synthesize stereophonic sound signals intended for the operator, and means to convert said target locating data into control data for a synthesis of stereophonic signals so that the operator gets a subjective sensation of a direction of attack corresponding to an actual direction of a target with respect to said operator, wherein said means for synthesizing stereophonic sound signals comprises a read only memory containing binary signals that correspond to a given target, an output of said memory being applied to a digital/analog converter which has its own output applied to two stereophonic amplifiers.
Claim 5
Dependent Claim
28 words
A device according to claim 2 wherein different types of binary signals are stored in said read only memory, said binary signals corresponding to different types of targets.
Claim 6
Dependent Claim
107 words
A weapon system comprising a target detection and locating system for delivering target locating data including at least an actual direction, a distance and an approach speed for a target, synthesizing means for synthesizing sound signals intended for an operator of the weapon system; and converting means for receiving said target locating data from said target detection and locating system and for converting said target locating data into control data for said synthesizing means so that said synthesizing means synthesizes sound such that said operator gets a subjective sensation of a direction of attack corresponding to said actual direction of said target with respect to said operator.
Claim 7
Dependent Claim
107 words
A weapon system comprising a target detection and locating system for delivering target locating data including at least an actual direction, a distance and an approach speed for a target, synthesizing means for synthesizing sound signals intended for an operator of the weapon system; and converting means for receiving said target locating data from said target detection and locating system and for converting said target locating data into control data for said synthesizing means so that said synthesizing means synthesizes sound such that said operator gets a subjective sensation of a direction of attack corresponding to said actual direction of said target with respect to said operator.
Claim 8
Dependent Claim
29 words
A system according to claim 4 wherein said direction data is combined, after conversion by said converting means, with data indicating a direction in which the operator is looking.
Claim 9
Dependent Claim
31 words
A system according to claim 4 wherein said converting means comprises a computer that converts said target-locating data on direction, distance and approaching speed into phase, intensity and frequency data, respectively.
Claim 10
Dependent Claim
62 words
A system according to claim 4 wherein said means for synthesizing stereophonic sound signals comprises a read-only memory having an output and addressing inputs and containing binary signals that correspond to a given target, a digital to analog converter having an input receiving said output of said memory and an output and two stereophonic amplifiers connected to said output of said converter.
Claim 11
Dependent Claim
60 words
A system according to claim 7, wherein said target-locating data comprise in addition data concerning characteristics of said target, wherein said read-only memory contains binary signals corresponding to different types of targets and wherein said data concerning the characteristics of said target are applied to said addressing inputs of said memory for selecting said binary signals corresponding to said target.
Claim 12
Dependent Claim
106 words
A weapon system comprising a target detection and locating system for delivering target locating data including at least an actual direction, a distance and an approach speed for a target, converting means for receiving said target locating data and for converting the target locating data into control data, and sound synthesizing means for receiving said control data and for synthesizing stereophonic sound signals intended for an operator of said weapon system in response to said control data, said stereophonic sound signals providing the operator with a subjective sensation of a direction of attack corresponding to said actual direction of said target with respect to said operator.
Claim 13
Dependent Claim
106 words
A weapon system comprising a target detection and locating system for delivering target locating data including at least an actual direction, a distance and an approach speed for a target, converting means for receiving said target locating data and for converting the target locating data into control data, and sound synthesizing means for receiving said control data and for synthesizing stereophonic sound signals intended for an operator of said weapon system in response to said control data, said stereophonic sound signals providing the operator with a subjective sensation of a direction of attack corresponding to said actual direction of said target with respect to said operator.
