Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
134 words
A fuze system for bomblets dropped in a cluster to detonate a majority of the bomblets above the ground for greater effectiveness, comprising: a. a greater majority of the bomblets in said cluster, each containing an RF receiver means; b. a transmitter means in at least one bomblet of said cluster; c. said RF receiver means comprising an antenna connected to an RF receiver, which in turn is connected to a detonator; d. said transmitter means comprising a high explosive electric pulse generating means connected to an RF transmission circuit which in turn is connected to a transmitting antenna; e. said high explosive electric pulse generating means being detonated by a contact fuze connected thereto; f. said high explosive electric pulse generating means comprising an explosive magnetic flux compressor which produces high current pulses.
Claim 2
Dependent Claim
134 words
A fuze system for bomblets dropped in a cluster to detonate a majority of the bomblets above the ground for greater effectiveness, comprising: a. a greater majority of the bomblets in said cluster, each containing an RF receiver means; b. a transmitter means in at least one bomblet of said cluster; c. said RF receiver means comprising an antenna connected to an RF receiver, which in turn is connected to a detonator; d. said transmitter means comprising a high explosive electric pulse generating means connected to an RF transmission circuit which in turn is connected to a transmitting antenna; e. said high explosive electric pulse generating means being detonated by a contact fuze connected thereto; f. said high explosive electric pulse generating means comprising an explosive magnetic flux compressor which produces high current pulses.
Claim 3
Dependent Claim
41 words
A fuze system as in claim 1 wherein an over-ride contact fuze is provided in each receiving bomblet connected to said detonator for initiating the bomblet if it hits the ground prior to receiving an RF signal from a transmitting bomblet.
Claim 4
Dependent Claim
20 words
A system as in claim 1 wherein each bomblet of said cluster contains both RF receiving means and transmitting means.
Claim 5
Dependent Claim
117 words
A fuze system for bomblets dropped in a cluster to detonate a majority of the bomblets abovE the ground for greater effectiveness, comprising: a. a greater majority of the bomblets in said cluster, each containing an RF receiver means; b. a transmitter means in at least one bomblet of said cluster; c. said RF receiver means comprising an antenna connected to an RF receiver, which in turn is connected to a detonator; d. said transmitter means comprising a high explosive electric pulse generating means connected to a transmitting antenna; e. said high explosive electric pulse generating means being detonated by a contact fuze connected thereto; f. said high explosive pulse generating means comprising a ferroelectric explosively-driven transducer.
Claim 6
Dependent Claim
117 words
A fuze system for bomblets dropped in a cluster to detonate a majority of the bomblets abovE the ground for greater effectiveness, comprising: a. a greater majority of the bomblets in said cluster, each containing an RF receiver means; b. a transmitter means in at least one bomblet of said cluster; c. said RF receiver means comprising an antenna connected to an RF receiver, which in turn is connected to a detonator; d. said transmitter means comprising a high explosive electric pulse generating means connected to a transmitting antenna; e. said high explosive electric pulse generating means being detonated by a contact fuze connected thereto; f. said high explosive pulse generating means comprising a ferroelectric explosively-driven transducer.
Claim 7
Dependent Claim
41 words
A fuze system as in claim 4 wherein an override contact fuze is provided in each receiving bomblet connected to said detonator for initiating the bomblet if it hits the ground prior to receiving an RF signal from a transmitting bomblet.
Claim 8
Dependent Claim
20 words
A system as in claim 4 wherein each bomblet of said cluster contains both RF receiving means and transmitting means.
